1. Business

Cara Therapeutics, Inc., or the Company, is a commercial-stage biopharmaceutical corporation formed on July 2, 2004. The Company is leading a new treatment paradigm to improve the lives of patients suffering from pruritus. The Company’s primary activities to date have been organizing and staffing the Company, developing its lead product and product candidates, including conducting preclinical studies and clinical trials of difelikefalin-based product candidates, and raising capital.

In August 2021, the Company received U.S. Food and Drug Administration, or FDA, approval for KORSUVA® (difelikefalin) injection, or KORSUVA injection, for the treatment of moderate-to-severe pruritus associated with chronic kidney disease in adults undergoing hemodialysis. Commercial launch of KORSUVA injection began in the United States in April 2022 and the Company began recording the associated profit-sharing revenues in the second quarter of 2022.

In April 2022, the European Commission granted marketing authorization to difelikefalin injection under the brand name Kapruvia® (difelikefalin), or Kapruvia, for the treatment of moderate-to-severe pruritus associated with chronic kidney disease in adult hemodialysis patients. The marketing authorization approved Kapruvia for use in all member states of the European Union, or EU, as well as Iceland, Liechtenstein, and Norway. Kapruvia was also approved in the United Kingdom in April 2022. Commercial launches in Austria, Germany, Sweden, France, the Netherlands, and Finland have commenced. In August 2022, as part of the Access Consortium, difelikefalin injection was approved in Switzerland under the brand name Kapruvia, as well as Singapore and Canada under the brand name KORSUVA. Commercial launch in Switzerland has also commenced. In November 2022, difelikefalin injection was approved in the last Access Consortium country, Australia, under the brand name KORSUVA. Difelikefalin injection was also approved in the United Arab Emirates, Kuwait, and Israel under the brand name KORSUVA in January 2023, May 2023, and June 2023, respectively. The Company hasexpects additional commercial launches to commence over the next 12-18 months.

In 2018, the Company entered into a license and collaboration agreement with a joint venture between Vifor Pharma Group and Fresenius Medical Care Renal Pharmaceutical Ltd., or Vifor Fresenius Medical Care Renal Pharma Ltd., that provides full commercialization rights of Kapruvia, and where applicable KORSUVA, to Vifor Fresenius Medical Care Renal Pharma Ltd. worldwide (excluding the United States, Japan and South Korea). In markets outside of the United States, the Company is eligible to receive tiered double-digit royalty payments based on annual net sales, as defined in the agreement with Vifor Fresenius Medical Care Renal Pharma Ltd., of difelikefalin injection in the licensed territories. In the U.S. market, the agreement with Vifor Fresenius Medical Care Renal Pharma Ltd. provides that Vifor Fresenius Medical Care Renal Pharma Ltd. will promote difelikefalin injection in the dialysis clinics of Fresenius Medical Care North America, or FMCNA, under a profit-sharing arrangement, whereby the Company is generally entitled to 50% of the annual net profits (as defined in the agreement with Vifor Fresenius Medical Care Renal Pharma Ltd.) based on net FMCNA clinic sales (as defined in the agreement with Vifor Fresenius Medical Care Renal Pharma Ltd.) and Vifor Fresenius Medical Care Renal Pharma Ltd. is entitled to 50% of such net profits, subject to potential adjustments in a calendar year based on certain conditions (see Note 11, Collaboration and Licensing Agreements).

In 2020, the Company entered into a second licensing and collaboration agreement, along with stock purchase agreements, with Vifor (International) Ltd., or Vifor International, that provides full commercialization rights of KORSUVA injection to Vifor International in dialysis clinics in the U.S.United States under a profit-sharing arrangement, whereby total net sales of KORSUVA injection in the U.S.,United States, as recorded by Vifor International, are reduced by Vifor International’s cost of goods sold, or COGS, as well as a marketing and distribution fee owed by the Company based on the level of annual net sales, and the resulting amount is shared according to a 60% (Company)/40% (Vifor International) profit split (excluding sales to Fresenius Medical Center dialysis clinics, compensation for which is governed by the agreement with Vifor Fresenius Medical Care Renal Pharma Ltd., or Vifor), subject to potential temporary adjustment in future years based on certain conditions (see Note 11, Collaboration and Licensing Agreements). Commercial launch of KORSUVA injection began in the U.S. in April 2022 and the Company began recording the associated profit-sharing revenues in the second quarter of 2022. In May 2022, as permitted by the agreements with Vifor International, Vifor International assigned its rights and obligations under the license agreement and a related supply agreement to Vifor. The Company’s rights and obligations under these agreements were unaffected by this assignment and the assignment does not affect the Company’s economic rights under the agreements. Throughout the Notes to Condensed Financial Statements, unless the context requires otherwise, references to Vifor’s commercialization of KORSUVA injection pursuant to this license agreement, and the Company’s provision of KORSUVA injection under this supply agreement, should be understood to refer to Vifor International prior to the assignment and to Vifor following the assignment, as applicable. Vifor International was acquired by CSL Limited in August 2022. The acquisition of Vifor International by CSL did not affect any of the Company’s rights or obligations pursuant to its agreements with Vifor.

In April 2022, the European Commission granted marketing authorization to difelikefalin injection under the brand name Kapruvia® (difelikefalin), or Kapruvia, for the treatment of moderate-to-severe pruritus associated with chronic kidney disease in adult hemodialysis patients. The marketing authorization approves Kapruvia for use in all member states of the European Union, or EU, as well as Iceland, Liechtenstein, and Norway. Kapruvia was also approved in the UK in April 2022. In addition, as part of the Access Consortium, the product was approved in August 2022 in Switzerland as Kapruvia, as well as Singapore and Canada as KORSUVA. In 2018, the Company entered into a license agreement with Vifor that provides full commercialization rights of Kapruvia, and where applicable KORSUVA, to Vifor worldwide (excluding the U.S., Japan and South Korea). In markets outside of the U.S., the Company is eligible to receive tiered double-digit royalty payments based on annual net sales, as defined in the agreement with Vifor, of difelikefalin injection in the licensed territories. In the U.S. market, the agreement with Vifor provides that Vifor will promote difelikefalin injection in the dialysis clinics of Fresenius Medical Care North America, or FMCNA, under a profit-sharing arrangement, whereby the Company is generally entitled to 50% of the annual net profits (as defined in the agreement with Vifor) based on net FMCNA clinic sales (as defined in the agreement with Vifor) and Vifor is entitled to 50% of such net profits, subject to potential adjustments in a calendar year based on certain conditions (see Note 11,

The Company also has a license agreement with Maruishi Pharmaceutical Co. Ltd., or Maruishi, under which the Company granted Maruishi an exclusive license to develop, manufacture, and commercialize drug products containing difelikefalin for acute pain and/or uremic pruritus in Japan. In September 2022, Maruishi submitted a New Drug Application in Japan for approval of difelikefalin injection for the treatment of pruritus in hemodialysis patients (see Note 11, Collaboration and Licensing Agreements).

As of SeptemberJune 30, 2022,2023, the Company had raised aggregate net proceeds of approximately $519,600 from several rounds of equity financing, including its initial public offering, or IPO, which closed in February 2014 and four follow-on public offerings of common stock, which closed in July 2019, July 2018, April 2017 and August 2015, respectively, and the issuance of convertible preferred stock and debt prior to the IPO. Including profit share revenue and royalties, the Company hadhas also earned approximately $263,500$279,900 under its license and supply agreements for difelikefalin, primarily with Vifor International,CSL Vifor, Maruishi, and Chong Kun Dang Pharmaceutical Corp., or CKDP, and an earlier product candidate for which development efforts ceased in 2007. In October 2021, theThe Company has also received aggregate net proceeds of $44,969approximately $98,000 from the issuance and sale of 3,282,391 shares of the Company’s common stock to Vifor International in connection with U.S. regulatory approval for KORSUVA injection in August 2021. Additionally, in October 2020, the Company received net proceeds of $38,449 from the issuance and sale of 2,939,552 shares of the Company’s common stock to Vifor International in connection with the Company’s licenselicensing agreement with Vifor International. Furthermore, in May 2018, the Company received net proceeds of $14,556 from the issuance and sale of 1,174,827 shares of the Company’s common stock to Vifor International in connection with the Company’s license agreement withCSL Vifor (see Note 11, Collaboration and Licensing Agreements).

The Company has incurred substantial net losses and negative cash flows from operating activities in nearly every fiscal period since inception and expects this trend to continue for the foreseeable future. The Company recognized net losses of $23,180$31,479 and $1,013$4,206 for the three months ended SeptemberJune 30, 20222023 and 2021,2022, respectively, and $55,135$58,144 and $55,059$31,955 for the ninesix months ended SeptemberJune 30, 20222023 and 2021,2022, respectively, and had net cash used in operating activities of $55,220$55,063 and $58,842$30,028 for the ninesix months ended SeptemberJune 30, 20222023 and 2021,2022, respectively.

The Company is subject to risks common to other life science companies including, but not limited to, uncertainty of product development and commercialization, lack of marketing and sales history, development by its competitors of new technological innovations, dependence on key personnel, market acceptance of products, product liability, protection of proprietary technology, ability to raise additional financing, and compliance with FDA and other government regulations. If the Company does not successfully commercialize KORSUVA injection, Kapruvia or any of its other product candidates, it will be unable to generate additional recurring product revenue or achieve profitability.

management, these unaudited interim financial statements reflect all adjustments, consisting primarily of normal recurring accruals, necessary for a fair presentation of results for the periods presented. The results of operations for interim periods are not necessarily indicative of the results for the full year. Certain information and footnote disclosures

(unaudited)

normally included in financial statements prepared in accordance with GAAP have been condensed or omitted from this report, as is permitted by SEC rules and regulations; however, the Company believes that the disclosures are adequate to make the information presented not misleading. The condensed balance sheet data as of December 31, 20212022 were derived from audited financial statements, but do not include all disclosures required by GAAP. These unaudited interim condensed financial statements should be read in conjunction with the audited financial statements and accompanying notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.2022.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, as of the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. The more significant estimates include the fair value of marketable securities that are classified as level 2 of the fair value hierarchy, revenue recognition associated with profit-sharing arrangements, the amount and periods over which certain revenues will be recognized, including licensing and collaborative revenue recognized from non-refundable up-front and milestone payments, related party accounts receivable net – related party,reserve, as applicable, inventory valuation and related reserves, the determination of prepaid research and development, or R&D, clinical costs and accrued research projects included in prepaid expenses and accounts payable and accrued expenses, the amount of non-cash compensation costs related to share-based payments to employees and non-employees, the incremental borrowing rate used in lease calculations and the likelihood of realization of deferred tax assets.

The impact from global economic conditions and potential and continuing disruptions to and volatility in the credit and equity markets in the United States and worldwide are highly uncertain and cannot be predicted, including impacts from the COVID-19 pandemic andor future public health crises, geopolitical tensions, such as Russia’s incursion intothe ongoing military conflict between Russia and Ukraine resulted in a global slowdown of economic activity,and related sanctions against Russia, decades-high inflation, rising interest rates, uncertainty and liquidity concerns in the broader financial services industry, such as those caused by certain recent banking failures, and a potential recession in the U.S.United States. Estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require the exercise of judgment. As of the date of issuance of these condensed financial statements, the Company is not aware of any specific event or circumstance that would require the Company to update its estimates, assumptions and judgments or revise the reported amounts of assets and liabilities or the disclosure of contingent assets and liabilities. These estimates, however, may change as new events occur and additional information is obtained, and are recognized in the condensed financial statements as soon as they become known.

Actual results could differ materially from the Company’s estimates and assumptions.

Significant Accounting Policies

There have been no material changes to the significant accounting policies previously disclosed in Note 2 to the Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, except as disclosed below.

Accounts Receivable, Net – Related Party

Accounts receivable, net – related party consists of amounts due from sales of KORSUVA injection under the Company’s supply agreements with Vifor, as well as revenues earned from its profit-sharing agreement from sales of KORSUVA injection in the U.S. under the licensing agreements with Vifor. The Company does not obtain collateral for its accounts receivable.

The Company makes judgments as to its ability to collect outstanding receivables and provides an allowance for credit losses when collection becomes doubtful. Provisions are made based upon a specific review of all significant outstanding invoices and the overall quality and age of those invoices not specifically reviewed. The Company believes that credit risk associated with its licensing partner, Vifor, is not significant. The Company reviews the need for an

8

NOTES TO CONDENSED FINANCIAL STATEMENTS

(amounts in thousands, except share and per share data)

(unaudited)

allowance for credit losses for any receivable based on various factors including payment history and historical bad debt experience. The Company had an insignificant allowance for credit losses as of September 30, 2022.

Revenue Recognition – Profit-Sharing Arrangement

The Company receives its share of the net profits from Vifor’s sale of KORSUVA injection to third parties in the U.S. under its existing license agreements. The Company has adopted a policy to recognize revenue net of tax withholdings, as applicable.

The Company determined that Vifor is a customer under Accounting Standards Update, or ASU, 2014-09, Revenue from Contracts with Customers (Topic 606), as amended by ASU 2016-08, 2016-10, 2016-12 and 2016-20, or ASC 606, in relation to its profit share arrangement with Vifor. The Company sells commercial product to Vifor, who ultimately sells the commercial product to third parties. The Company’s profit share arrangement revenues generated from sales of KORSUVA injection in the U.S. are considered akin to sales-based royalties. In accordance with the sales-based royalty exception, the Company recognizes its share of the pre-tax commercial net profit generated from the sales of KORSUVA injection in the U.S. in the period the product sales are earned, as reported by Vifor. The related COGS for Vifor associated with the net profit share arrangement as well as the marketing and distribution fee for the applicable period reduces the Company’s profit share revenue for the period. The net sales amounts are determined based on amounts provided by Vifor and involve the use of estimates and judgments, such as product sales allowances and accruals related to prompt payment discounts, chargebacks, governmental and contractual rebates, wholesaler fees, product returns, and co-payment assistance costs, which could be adjusted based on actual results in the future. The Company is dependent on Vifor for timely and accurate information regarding the net revenues from sales of KORSUVA injection in the U.S. in accordance with ASC 606 to accurately report its results of operations. If the Company does not receive timely and accurate information or incorrectly estimates activity levels associated with the profit share arrangement at a given point in time, the Company could be required to record adjustments in future periods.

In accordance with ASC 606-10-55, Principal Agent Considerations, the Company records revenue transactions as net product revenue if it is deemed the principal in the transaction, which includes being the primary obligor, retaining inventory risk, and control over pricing. Given that the Company is not the primary obligor and does not have the inventory risks in the license agreement with Vifor, it records its share of the net profits from the sales of KORSUVA injection in the U.S. on a net basis and presents the settlement payments from Vifor as Collaborative revenue. The Company and Vifor settle the profit sharing quarterly (see Note 11, Collaboration and Licensing Agreements).

3. Available-for-Sale Marketable Securities

As of September 30, 2022 and December 31, 2021, the Company’s available-for-sale marketable securities consisted of debt securities issued by the U.S. Treasury, U.S. government-sponsored entities and investment grade institutions as well as municipal bonds.

As of September 30, 2022 and December 31, 2021, the Company held a total of 57 out of 57 positions and 58 out of 76 positions, respectively, that were in an unrealized loss position, 18 of which had been in an unrealized loss position for 12 months or greater as of September 30, 2022. Unrealized losses individually and in aggregate were not considered to be material for each respective period. Based on the Company’s review of these securities, the Company believes that the cost basis of its available-for-sale marketable securities is recoverable.

U.S. Treasury and U.S. government agency obligations. The unrealized losses on the Company’s investments in direct obligations of U.S. Treasury and government agencies were due to changes in interest rates and non-credit related factors. The credit ratings of these investments in the Company’s portfolio have not been downgraded below investment grade status. The contractual terms of these investments do not permit the issuer to repay principal at a price less than the amortized cost bases of the investments, which is equivalent to the par value on the maturity date. The Company expects to recover the entire amortized cost bases of these securities on the maturity date. The Company does not intend to sell these investments, and it is not “more likely than not” that the Company will be required to sell these investments before recovery of their amortized cost bases. The Company held two out of two positions for its U.S. Treasury securities, and

three out of three positions for its U.S. government agency obligations, that were in unrealized loss positions as of September 30, 2022.

Corporate bonds, commercial paper, and municipal bonds. The unrealized losses on the Company’s investments in corporate bonds, commercial paper and municipal bonds were due to changes in interest rates and non-credit related factors. The credit ratings of these investments in the Company’s portfolio have not been downgraded below investment grade status. The contractual terms of these investments do not permit the issuer to repay principal at a price less than the amortized cost bases of the investments, which is equivalent to the par value on the maturity date. The Company expects to recover the entire amortized cost bases of these securities on the maturity date. The Company does not intend to sell these investments, and it is not “more likely than not” that the Company will be required to sell these investments before recovery of their amortized cost bases. The Company held 15 out of 15 positions for its corporate bonds, 22 out of 22 positions for its commercial paper, and 15 out of 15 positions for its municipal bonds, that were in unrealized loss positions as of September 30, 2022.

The information that the Company considered in reaching the conclusion that an allowance for credit losses was not necessary is as follows:

As of June 30, 2023 and December 31, 2022, the Company held a total of 17 out of 22 positions and 35 out of 39 positions, respectively, that were in an unrealized loss position, all of which had been in an unrealized loss position for 12 months or greater as of June 30, 2023.

Based on the Company’s review of these securities, the Company believes that the cost basis of its available-for-sale marketable securities is recoverable.

U.S. government agency obligations.

The Company expects to recover the entire amortized cost bases of these securities on the maturity date. The Company does not intend to sell these investments, and it is not “more likely than not” that the Company will be required to sell these investments before recovery of their amortized cost bases. The Company held 3 out of 3 positions for its U.S. government agency obligations, that were in unrealized loss positions as of June 30, 2023.

The Company is required to maintain a stand-by letter of credit as a security deposit under the New Lease and its existing leases for its office spacespaces in Stamford, Connecticut (refer to Note 16, Commitments and Contingencies: Leases).

As of SeptemberJune 30, 2022,2023, the restricted cash balancebalances for the StamfordNew Lease wasand the existing leases were invested in a commercial money market account.

Under Vifor Agreement No. 1, in consideration of CSL Vifor’s conduct of the marketing, promotion, selling and distribution of difelikefalin injection in the U.S.,United States, the Company pays a marketing and distribution fee to CSL Vifor based on the level of annual net sales.

The Company retains the rights to make and have made difelikefalin injection, or the Licensed Product, on a non-exclusive basis, in the U.S.United States for commercial sale of the Licensed Product for use in all therapeutic usesareas to prevent, inhibit or treat itch associated with pruritus in hemodialysis and peritoneal-dialysis patients, or the Field, anywhere in the world and for supply of Licensed Product to CSL Vifor International under the terms of a supply agreement, or the Vifor International Supply Agreement, which was executed in September 2021. The supply price is the Company’s COGS, as calculated under GAAP, plus an agreed upon margin. The Vifor International Supply Agreement will co-terminate with Vifor Agreement No. 1. The Company also retains the rights to import, distribute, promote, sell and otherwise commercialize the Licensed Product on an exclusive basis outside of the Field either in or outside of the United States.

The Vifor International Supply Agreement is accounted for as a customer option that is not a material right because the selling price of the Licensed Product under the Vifor International Supply Agreement is the Company’s COGS plus an agreed upon margin, which is commensurate with the “COGS plus” model that the Company would charge other parties under similar agreements (the standalone selling price) and not at a discount. Therefore, the sale of commercial supply to CSL Vifor International is not a performance obligation under Vifor Agreement No. 1 but rather the Vifor International Supply Agreement is a separate agreement from Vifor Agreement No. 1. The only performance obligation under the Vifor International Supply Agreement is the delivery of the Licensed Product to CSL Vifor International for commercialization.

In May 2022, as permitted by Vifor Agreement No. 1 and the Vifor International Supply Agreement, Vifor International assigned its rights and obligations under these agreements to Vifor. The Company’s rights and obligations under these agreements were unaffected by this assignment, and the assignment does not affect the Company’s economic rights under the agreements. Throughout the Notes to Condensed Financial Statements, unless the context requires otherwise, references to Vifor’s commercialization of KORSUVA injection pursuant to the license agreement, and the Company’s provision of KORSUVA injection under this supply agreement, should be understood to refer to Vifor International prior to the assignment and to Vifor following the assignment, as applicable.

The supply price is the Company’s COGS, as calculated under GAAP, plus an agreed upon margin. The Vifor Supply Agreement will co-terminate with Vifor Agreement No. 2.

Therefore, the sale of compound to Vifor Fresenius Medical Care Renal Pharma Ltd. is not a performance obligation under Vifor Agreement No. 2 but rather the Vifor Supply Agreement is a separate agreement from Vifor Agreement No. 2.

The Company has recognized a full tax valuation allowance against its deferred tax assets as of SeptemberJune 30, 20222023 and December 31, 2021.2022. The tax benefit related to the exercise of stock options is recognized as a deferred tax asset that is offset by a corresponding valuation allowance. As such, the Company’s effective tax rate is zero for each of the three and ninesix months ended SeptemberJune 30, 20222023 and 2021.2022.

Historically, the Company’s benefit from income taxes relatesrelated to state R&D tax credits exchanged for cash pursuant to the Connecticut R&D Tax Credit Exchange Program, which permits qualified small businesses engaged in R&D activities within Connecticut to exchange their unused R&D tax credits for a cash amount equal to 65% of the value of the exchanged credits. Because the Company’s revenue in 2020 exceeded $70,000, itIt was not eligible to exchange its 2021 R&D tax credit for cash during the three and six months ended June 30, 2023 and 2022, therefore there was no benefit from income taxes for the three and ninesix months ended SeptemberJune 30, 2021.2023 and 2022.

Overview

We are a commercial-stage biopharmaceutical company leading a new treatment paradigm to improve the lives of patients suffering from pruritus. Our novel KORSUVA injection is the first and only U.S. Food and Drug Administration, or FDA, approved treatment for moderate-to-severe pruritus associated with chronic kidney disease, or CKD, in adults undergoing hemodialysis. We are developing an oral formulation of difelikefalin and have initiated Phase 3 programs for the treatment of pruritus in patients with advanced NDD chronic kidney diseaseCKD and atopic dermatitis, or AD. We have completedalso initiated a Phase 2 proof-of-concept trial2/3 program of oral difelikefalin for the treatment of moderate-to-severe pruritus in patients with NP.

On August 23, 2021, our lead product, KORSUVA injection, was approved by the FDA for the treatment of moderate-to-severe pruritus associated with CKD in adults undergoing hemodialysis in the U.S.United States. In December 2021, CMS granted Transition Drug Add-on Payment Adjustment, or TDAPA, to KORSUVA injection in the anti-pruritic functional category. TDAPA went into effect on April 1, 2022, for a minimum of two years. CommercialOn June 26, 2023, CMS issued the Calendar Year, or CY, 2024 ESRD PPS proposed rule to update Medicare payment policies and rates for renal dialysis services including a proposed methodology for post-TDAPA reimbursement for TDAPA designated products in existing functional categories. CMS is expected to issue a final CY 2024 rule in the fourth quarter of 2023. The commercial launch of KORSUVA injection begancommenced in April 2022 and we began recording the associated profit-sharing revenues in the second quarter of 2022. We are partnering with CSL Vifor to commercialize KORSUVA injection in dialysis patients with CKD-aP worldwide, excluding Japan (Maruishi/sub-licensee Kissei), and South Korea (CKDP).

In April 2022, the European Commission granted marketing authorization to difelikefalin injection under the brand name Kapruvia for the treatment of moderate-to-severe pruritus associated with chronic kidney disease in adult hemodialysis patients. The marketing authorization approves Kapruvia for use in all member states of the European Union, or EU, as well as Iceland, Liechtenstein, and Norway. Kapruvia was also approved in the UK in April 2022. Commercial launches in Austria, Germany, Sweden, France, the Netherlands, and Finland have commenced. In August 2022, as part of the Access Consortium, difelikefalin injection was approved in Switzerland under the brand name Kapruvia, as well as in Singapore and Canada under the brand name KORSUVA. Commercial launcheslaunch in AustriaSwitzerland has also commenced. In November 2022, difelikefalin injection was approved in the last Access Consortium country, Australia, under the brand name KORSUVA. Difelikefalin injection was also approved in the UAE, Kuwait, and Germany have commencedIsrael under the brand name KORSUVA in January 2023, May 2023, and weJune 2023, respectively.

In August 2022, Vifor Pharma Group (which includes Vifor International) was acquired by CSL Limited and Fresenius Medical Care,subsequently renamed CSL Vifor as part of the acquisition. The acquisition of Vifor Pharma Group did not affect any of the Company’s rights and obligations pursuant to these agreements.

We are partnering with CSL Vifor International to commercialize KORSUVA injection in dialysis patients with CKD-aP worldwide, excluding Japan (Maruishi/sub-licensee Kissei), and South Korea (CKDP). CSL Vifor Pharma Group is a leading nephrology commercial organization with a significant presence in nephrology offices and dialysis centers. In the U.S.,United States, we are launchinglaunched KORSUVA injection into a highly concentrated market. The dialysis market is dominated by two keylarge dialysis organizations, or LDOs, Fresenius Medical Care, or FMC, and DaVita, which combined control about 75% of the market. In addition, reimbursement is dominated by Medicare which covers about 80% of the CKD hemodialysis patients are insured by Medicare.patients. Outside of the U.S.,United States, the dialysis market is not dominated by largeany corporate dialysis companies and is a much more fragmented market than in the U.S. EachUnited States. Furthermore, each country will havehas its own unique reimbursement system for hemodialysis patients.

We have built a pipeline around an oral formulation of difelikefalin, the active compound in KORSUVA injection and Kapruvia. We are developing oral difelikefalin in multiple therapeutic areas to createOur strategy is focused on maximizing the potential opportunities across three disease categories (systemic, dermatologic, and neurologic) with chronic pruritus. This platformutility of oral difelikefalin across our two core franchises: nephrology and medical dermatology. We have an active late-stage pipeline of oral difelikefalin that addresses broad, underserved, significant markets in nephrology and dermatology. We have three potentially pivotal programs is designed to significantly expand the addressable marketunderway for chronic pruritus in: a) CKD; b) AD; and patient populations that might benefit from our compound. We currently have four clinical programs in therapeutic areas totaling about 16 million potential patients with chronic pruritus: advanced NDD-CKD, AD, NP and PBC.c) NP.

Based on our completed Phase 2 trials and successful End of Phase 2 meetings with the FDA, we initiated two Phase 3 clinical programs of oral difelikefalin for the treatment of chronic pruritus, one in NDD-CKDadvanced CKD and the other in AD, in the first quarter of 2022.

In June 2022, we announced positive topline results from the proof-of-conceptas well as a Phase 2 KOMFORT trial2/3 program of oral difelikefalin for the treatment of moderate-to-severe pruritus in patients with NP (a neurologic condition in which chronic pruritus is the key manifestation). In September 2022, we announced positive results from the extension phasefirst quarter of the Phase 2 KOMFORT trial. This condition currently has no FDA-approved treatments nor robust data to support the use of any single therapy.2023.

We were incorporated and commenced operations in 2004, and our primary activities to date have been organizing and staffing our company, developing our lead product and product candidates, including conducting preclinical studies and clinical studiestrials of difelikefalin-based product candidates and raising capital. To date, we have financed our operations primarily through sales of our equity and debt securities and payments from license agreements.

Recent Developments

KORSUVA Injection Launch Progress

In April 2022, we started the commercialization of KORSUVA injection in the U.S. through the collaboration with Vifor. The commercial launch is in the early stages but tracking to our expectations. KORSUVA injection’s uptake was initially driven by independent and mid-size organizations. In the third quarter of 2022, large dialysis organizations, or LDOs, started to order driving an acceleration in volume sales. Given the highly concentrated market, we expect LDOs to be the main contributor to product demand long-term. In the third quarter of 2022, Vifor also contracted the sales force of Fresenius Renal Pharmaceuticals, a division of Fresenius Medical Care North America, to complement Vifor’s sales force in selling into Fresenius clinics in the U.S.

Appointments

We appointed Ryan Maynard to the position of Chief Financial Officer, or CFO, in September 2022. As a member of our Executive Leadership Team, Mr. Maynard leads our financial operations.

We appointed Lisa von Moltke, M.D., to our Board of Directors in November 2022.

COVID-19 Update

The extent of the impact of the COVID-19 pandemic, including the resulting adverse macroeconomic conditions, on our business, operations and clinical development and regulatory timelines and plans remains uncertain, and will depend on certain developments, including the duration and outbreak and spread of variants and its impact on our clinical trial enrollment, trial sites, partners, CROs, third-party manufacturers, and other third parties with whom we do business, as well as its impact on regulatory authorities and our key scientific and management personnel. The COVID-19 pandemic, however, affected the initiation of certain trial sites and patient enrollment for our ongoing Phase 2 clinical trial of oral difelikefalin for the treatment of pruritus in patients with hepatic impairment due to PBC. While we currently do not expect any significant delays in our clinical development or commercial timelines, the ultimate impact of the evolving COVID-19 pandemic remains difficult to predict.

To the extent possible, we are conducting business as usual, with necessary or advisable modifications to employee travel and employee work locations. We are continuing to actively monitor the constantly evolving situation related to COVID-19 and may take further actions that alter our operations, including those that may be required by federal, state or local authorities, or that we determine are in the best interests of our employees, partners and other third-parties with whom we do business. The extent to which the COVID-19 pandemic may affect our business, operations and clinical development and regulatory timelines and plans, including the resulting impact on our expenditures and capital needs, remains uncertain.

DifelikefalinOur Nephrology Franchise

KORSUVA (difelikefalin) injection – Our LeadCommercial Product

Our product candidate, difelikefalin, is a new chemical entity, which is designed to selectively stimulate kappa, rather than mu, and delta opioid receptors. Difelikefalin has been designed with specific chemical characteristics to restrict its entry into the central nervous system, or CNS, and further limit its mechanism of action to kappa opioid receptors, or KORs, in the peripheral nervous system and on immune cells. Activation of kappa receptors in the CNS is known to result in some undesirable effects, including dysphoria. Since difelikefalin modulates kappa receptor signals peripherally without any significant activation of opioid receptors in the CNS, it is generally not expected to produce the CNS-related side effects of mu opioid agonists (such as addiction and respiratory depression) or centrally-active kappa opioid agonists (such as dysphoria and hallucinations). Difelikefalin has been administered to more than 3,000 human

subjects in Phase 1, Phase 2 and Phase 3 clinical trials as an I.V. infusion, bolus intravenous injection or oral capsule or tablet, and thus far has been observed to be generally well tolerated.

Based on the non-clinical and clinical studies we have completed to date, we believe that oral difelikefalin, if approved for any or multiple indications, would be attractive to both patients and healthcare providers as a potential treatment for chronic pruritus across the spectrum of systemic, neurologic, and dermatologic disease categories.

KORSUVA Injection for Moderate-to-Severe Pruritus Associated with CKD in Adults Undergoing Hemodialysis

Chronic kidney disease, or CKD, is a clinical condition wherein progressive kidney damage leads to an impairment of kidney function over time. Primary risk factors culminating into CKD include diabetes, hypertension, cardiovascular disease, or hereditary renal disease. Early-stage disease is generally associated with few mild clinical manifestations; however, CKD can progress to kidney failure or ESRD which is fatal without dialysis or transplantation. According to the National Kidney Foundation, ESRD is estimated to affect approximately 750,000 individuals per year in the U.S., of which approximately 500,000 patients undergo regular dialysis.Overview

Chronic pruritus is one of the many comorbidities of CKD, characterized by a highly unpleasant and irritating sensation that triggers an urge to scratch the skin. CKD-aP adversely affects patient quality of life and can result in infections, sleep-deprivation, depression, and even increased risk of mortality.

CKD-aP’s intractable systemic itch has a high prevalence. According to Fresenius Medical Care, a world leading provider of products and medical care for dialysis patients, there were approximately 3.2 million patients globally undergoing dialysis in 2017. According to the Dialysis Outcomes and Practice Patterns Study published in December 2017 in the Clinical Journal of the American Society of Nephrologists, it is estimated that nearly 70% of these patients suffer from some form of CKD-aP with approximately 40% of these patients experiencing moderate to severe pruritus.

KORSUVA Injection Approved by the FDA in August 2021

KORSUVA injection was approved by the FDA onOn August 23, 2021, and is the first and onlyour lead product, KORSUVA injection, was approved by the FDA for the treatment of moderate-to-severe pruritus associated with CKD in adult patients undergoing hemodialysis. KORSUVA injection is not scheduled as a controlled substance. The clinical development program was the largest in CKD-aP patients undergoing hemodialysis with over 1,300 patients participating.

In June 2017, the FDA granted Breakthrough Therapy Designation to KORSUVA injection for the treatment of CKD-aP in hemodialysis patients. The KORSUVA injection New Drug Application received Priority Review by the FDA, which is granted to therapies that, if approved, would offer significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications.

KORSUVA injection is the first and only FDA-approved product in the U.S., Canada, and Singapore to treat CKD-aP in adults undergoing hemodialysis. Kapruvia is the only approved drug in Europe to treat CKD-aP. Patients are generally managed with a multitude of products including corticosteroids, gabapentin, antihistamines, antidepressants and others with limited efficacy and tolerability. There is one product, nalfurafine (Remitch®) marketed by Toray Industries, approved to treat CKD-aP in Japan, but it is not approved in either the U.S. or Europe.

In October 2020, we entered into a license agreement with Vifor International pursuant to which we granted Vifor International an exclusive license solely in the U.S. to use, distribute, offer for sale, promote, sell and otherwise commercialize KORSUVA injection for all therapeutic uses relating to the inhibition, prevention or treatment of itch associated with pruritus in hemodialysis and peritoneal dialysis patients.

Our U.S. commercial partner, Vifor Pharma Group (now CSL Vifor Pharma Group), submitted the payment reimbursement application for TDAPA and HCPCS to CMS in September 2021. In December 2021, CMS granted TDAPA designation to KORSUVA injection in the anti-pruritic functional category. TDAPA became effective for KORSUVA injectionwent into effect on April 1, 2022, for a minimum of two years. CMS expressedThe commercial launch of KORSUVA injection commenced in its written communication to usApril 2022 and we began

and Vifor, a continuing interest in engaging withrecording the companies regarding potential post-TDAPA support to ensure all beneficiaries with ESRD have access to innovative products such as KORSUVA injection.

Commercialization of KORSUVA injection in the U.S. commenced in April 2022 and we began recording associated profit-sharing revenues in the second quarter of 2022. On June 26, 2023, CMS issued the CY 2024 ESRD PPS proposed rule to update Medicare payment policies and rates for renal dialysis services including a proposed methodology for post-TDAPA reimbursement for TDAPA designated products in existing functional categories. CMS is expected to issue a final CY 2024 rule in the fourth quarter of 2023. We are partnering with CSL Vifor to commercialize KORSUVA injection in dialysis patients with CKD-aP worldwide, excluding Japan (Maruishi/sub-licensee Kissei), and South Korea (CKDP). For the three and six months ended June 30, 2023, CSL Vifor recorded net sales of KORSUVA injection in the United States of approximately $11.4 million and $17.1 million, respectively, and we recorded associated collaborative revenue of $5.4 million and $8.2 million, respectively, which represented our share of the profit from these sales.

In April 2022, the European Commission granted marketing authorization to difelikefalin injection under the brand name Kapruvia for the treatment of moderate-to-severe pruritus associated with CKD in adult hemodialysis patients. The marketing authorization approves Kapruvia for use in all member states of the EU, as well as Iceland, Liechtenstein, and Norway. Kapruvia was also approved in the UK in April 2022. Commercial launches in Austria, Germany, Sweden, France, the Netherlands, and Finland have commenced. In August 2022, as part of the Access Consortium, difelikefalin injection was approved in Switzerland under the brand name Kapruvia, as well as Singapore and Canada under the brand name KORSUVA. Commercial launch in Switzerland has also commenced. In November 2022, difelikefalin injection was approved in the last Access Consortium country, Australia, under the brand name KORSUVA. Difelikefalin injection was also approved in the UAE, Kuwait, and Israel under the brand name KORSUVA in January 2023, May 2023, and June 2023, respectively. For the three and six months ended June 30, 2023, we recorded royalty revenue of approximately $123,000 and $248,000, respectively, which represented our royalties on net sales of Kapruvia in Europe. We expect additional commercial launches to commence over the next 12-18 months.

In addition, our partner in Japan, Maruishi, announced positive Phase 3 top-line data in January 2022. Maruishi and its sublicensee Kissei confirmed the primary endpoint was achieved in a Japanese Phase 3 clinical study (double-blind, placebo-controlled period) of difelikefalin injection for the treatment of pruritus in hemodialysis patients. In the Phase 3 study, 178 patients were administered difelikefalin or placebo for 6 weeks followed by an open-label extension period of difelikefalin administration for 52 weeks. The primary endpoint, change in itch numerical rating scale, or NRS, and the secondary endpoint, change in itch scores of Shiratori severity criteria, were significantly improved from baseline compared to the placebo group. Difelikefalin was well-tolerated.

In September 2022, Maruishi submitted a New Drug Application in Japan for the approval of difelikefalin injection for the treatment of pruritus in hemodialysis patients. A final decision on the application is expected in the second half of 2023.

In January 2023, Vifor Fresenius Medical Care Renal Pharma Ltd. and Winhealth Pharma signed a long-term exclusive licensing agreement for the co-development and commercialization of KORSUVA injection for the treatment of moderate-to-severe pruritus in adult patients undergoing hemodialysis in China.

Summary of the Clinical Results for KORSUVA injection/Kapruvia:

KORSUVA injection was approved by the FDA on August 23, 2021 and is the first and only product approved for the treatment of moderate-to-severe pruritus associated with advanced CKD in adult patients undergoing hemodialysis.hemodialysis in the United States.

It was approved based on the NDA filing that was supported by positive data from two pivotal Phase 3 trials – KALMTM-1, conducted in the U.S.,United States, and KALM-2 conducted globally, as well as supportive data from an additional 32 clinical studies. KORSUVA injection was found to be generally well tolerated in the pivotal studies highlighted below.

In April 2020, we announced positive top-line results from the double blinded KALM-2 pivotal Phase 3 trial of KORSUVA injection in hemodialysis patients with moderate-to-severe CKD-aP. The study met the primary efficacy endpoint with 54% of the patients receiving 0.5 mcg/kg of KORSUVA injection vs. 42% of patients receiving placebo achieving at least a three-point improvement from baseline with respect to the weekly mean of the daily 24-hour worst

itch intensity numeric rating scale, or NRS score at week 12 (p= 0.02). The study also met the key secondary endpoint with 41% of patients receiving KORSUVA injection achieving a four-point or greater improvement from baseline in the weekly mean of the daily 24-hour worst itch NRS score at week 12 vs. 28% for patients receiving placebo (p= 0.01). In this trial, KORSUVA injection was generally well-tolerated with a safety profile consistent with that seen in KALM-1 and the KORSUVA clinical program in patients with CKD-aP.

Overall, the incidence of adverse effects, or AEs, and serious AEs were similar across both KORSUVA injection and placebo groups. The most common treatment emergent AEs reported in greater than 5% of patients were diarrhea (8.1% KORSUVA vs. 5.5% placebo), falls (6.8% KORSUVA vs. 5.1% placebo), vomiting (6.4% KORSUVA vs. 5.9% placebo), nausea (6.4% KORSUVA vs. 4.2% placebo) and dizziness (5.5% KORSUVA vs. 5.1% placebo).

In May 2019, we announced positive results from the double blinded phase of our KALM-1 pivotal Phase 3 trial of KORSUVA injection in hemodialysis patients with moderate-to-severe CKD-aP. The study met the primary efficacy endpoint with 51% of the patients receiving 0.5 mcg/kg of KORSUVA injection vs. 28% of patients receiving placebo achieving at least a three-point improvement from baseline with respect to the weekly mean of the daily 24-hour worst itch intensity NRS score at week 12 (p= 0.000019). The study also met all secondary endpoints, including assessment of itch-related quality of life changes measured using self-assessment Skindex-10 (patients receiving KORSUVA experienced 43% improvement vs. patients receiving placebo, p= 0.0004) and 5-D Itch scales (patients receiving KORSUVA experienced 35% improvement vs. patients receiving placebo, p= 0.0009). In addition, 39% of patients receiving KORSUVA injection achieved a four-point or greater improvement from baseline in the weekly mean of the daily 24-hour worst itch NRS score at week 12 vs. 18% of patients receiving placebo (p= 0.000032), another key secondary endpoint. In this trial, KORSUVA injection was generally well-tolerated with a safety profile consistent with that seen in earlier trials.

Overall, the incidence of AEs and serious AEs were similar across both KORSUVA injection and placebo groups. The most common treatment emergent AEs reported in greater than 5% of patients were diarrhea (9.5% KORSUVA vs. 3.7% placebo), dizziness (6.9% KORSUVA vs. 1.1% placebo), vomiting (5.3% KORSUVA vs. 3.2% placebo) and nasopharyngitis (3.2% KORSUVA vs. 5.3% placebo).

KORSUVA Injection U.S. Launch Progress

Update on

In April 2022, our partner CSL Vifor initiated the commercialization of KORSUVA injection outsidein the U.S.United States. The launch was initially driven by independent and mid-size dialysis organizations coupled with product stocking at the wholesaler level. In the third quarter of 2022, LDOs came on-line driving a significant quarter-to-quarter increase in order volume from the wholesaler. Specifically, Fresenius placed large orders to drive the trial and adoption of KORSUVA injection across its entire network of clinics. In the third quarter of 2022, CSL Vifor also contracted the sales force of Fresenius Renal Pharmaceuticals, a division of Fresenius Medical Care North America, to complement CSL Vifor’s sales force in selling into Fresenius clinics in the United States. After the initial inventory building at both the wholesaler and certain clinics (primarily, Fresenius), we have started to see shipments to dialysis organizations reflect true end-user demand versus the stocking activity seen in prior quarters. During the three and six months ended June 30, 2023, KORSUVA injection generated net sales of $11.4 million and $17.1 million, respectively, and we recorded collaborative revenue of $5.4 million and $8.2 million, respectively, which represented our share of the profit from sales of KORSUVA injection. Wholesalers shipped 66,852 and 112,572 vials to dialysis centers, the majority of which were Fresenius clinics, during the three and six months ended June 30, 2023, respectively. Vial orders grew 46% quarter to quarter, signifying an acceleration in patient demand.

Our partner, Vifor, submitted a Marketing Authorization Application, or MAA, to the European Medicines Agency, or EMA, in March 2021, which was subsequently accepted for review by the EMA. On April 27, 2022, the European Commission granted marketing authorization toKORSUVA Injection and Kapruvia for the treatment of moderate-to-severe pruritus associatedRevenue and Other Metrics

In addition, our partner in Japan, Maruishi, announced positive Phase 3 top-line data in January 2022. Maruishi and its sublicensee Kissei confirmed the primary endpoint was achieved in a Japanese Phase 3 clinical study (double-blind, placebo-controlled period) of difelikefalin injection for the treatment of pruritus in hemodialysis patients. In the Phase 3 study, 178 patients were administered difelikefalin or placebo for 6 weeks followed by an open-label extension period of difelikefalin administration for 52 weeks. The primary endpoint, change in itch NRS score, and the secondary endpoint, change in itch scores of Shiratori severity criteria, were significantly improved from baseline compared to the placebo group. Difelikefalin was well-tolerated.

In September 2022, Maruishi submitted a New Drug Application in Japan for the approval of difelikefalin injection for the treatment of pruritus in hemodialysis patients. A final decision on the application is expected in the second half of 2023.

Vifor has submitted a marketing application for difelikefalin injection via the Access Consortium (which includes applications to Canada, Switzerland, Australia, and Singapore) in the second quarter of 2021. In August 2022, the product was approved in Switzerland under the brand name Kapruvia, as well as Canada and Singapore under the brand name KORSUVA. A regulatory decision in Australia is expected by the end of 2022.

Oral difelikefalinDifelikefalin for the Treatment of Non-Dialysis-DependentAdvanced Chronic Kidney Disease (NDD-CKD) Associated Pruritus (CKD-aP)

CKD-aP (also known as uremic pruritus) is a frequent and wearisome symptom in patients with NDD-CKD (Stage I – V). We initiated a Phase 3 program with oral difelikefalin for the treatment of pruritus in NDD-CKD, specifically in patients diagnosed with Stage IV and V advanced CKD. There are approximately 1.2 million patients diagnosed with Stage IV and V CKD in the U.S. and approximately 300,000 of these patients suffer from moderate-to-severe pruritus.

There are no FDA-approved treatment options specifically for this indication in the U.S. or Europe. Patients are generally managed with a multitude of products including corticosteroids, gabapentin, antihistamines, antidepressants, and other therapies with varying degrees of success. There is one product, nalfurafine (Remitch®) marketed by Toray Industries, approved to treat CKD-aP in Japan, but it is not approved in either the U.S. or Europe.

In December 2019, we announced top-line data from our Phase 2 trial of oral difelikefalin for the treatment of pruritus in NDD–advanced CKD patients diagnosed with Stage III – V CKD. The Phase 2, multicenter, randomized, double-blind, placebo-controlled 12-week trial was designed to evaluate the safety and efficacy of three dosage strengths (0.25 mg, 0.5 mg and 1 mg, once daily administration) of oral difelikefalin vs. placebo in approximately 240 stage III - V (moderate-to-severe) CKD patients with moderate-to-severe pruritus. The primary efficacy endpoint was the change from baseline in the weekly mean of the daily 24-hour worst itch NRS score at week 12 of the treatment period. Secondary endpoints included change from baseline in itch-related quality of life scores at the end of week 12, as assessed by the total Skindex-10 and 5-D itch scores, as well as the proportion of patients achieving an improvement from baseline ≥3 points with respect to the weekly mean of the daily 24-hour worst itch NRS score at week 12.

Patients treated with the 1 mg dosage strength of oral difelikefalin achieved the primary endpoint of statistically significant reduction in weekly mean of the daily worst itch NRS scores vs. placebo after the 12-week treatment period (-4.4 difelikefalin vs. -3.3 placebo, p=0.018). The treatment was statistically significant after two weeks of treatment andwith sustained benefit through the 12-week treatment period. Regarding secondary endpoints, the proportion of patients on 1 mg tablet strength achieving a 3 point or greater improvement from baseline in the weekly mean of the daily worst itch NRS score at week 12 was 72% vs. 58% for placebo but did not achieve statistical significance. Furthermore, patients on 1 mg dosage strength showed positive improvements vs. placebo in itch quality of life endpoints as measured usingby the self-assessment Skindex-10 and 5-D Itch scales but thesethis did not achieve statistical significance.

Oral difelikefalin was generally well-tolerated with a safety profile consistent with that seen in earlier KORSUVA clinical trials. Overall, the incidence of treatment AEs were similar across difelikefalin and placebo groups. The most common AEs reported in >5% of patients in the 1 mg difelikefalin group vs. placebo were dizziness (7.5% difelikefalin vs. 0% placebo), fall (6% difelikefalin vs. 0% placebo), diarrhea (6% difelikefalin vs. 1.5% placebo) and constipation (6% difelikefalin vs. 3% placebo).

In April 2021, we held an End of Phase 2 Meeting with the FDA to discuss the results of the Phase 2 trial of oral difelikefalin in NDD CKD-aPadvanced CKD and the potential Phase 3 program. The FDA indicated the acceptability of Stage V pre-dialysis CKD patients as a viable patient population for a program. In November 2021, the FDA provided written guidance indicating the patient population can be expanded to include the group of Stage IV pre-dialysis patients with advanced CKD in a registration program consisting of two pivotal Phase 3 clinical trials.

The Phase 3 program consists of two identicalidentically designed trials (U.S. and global), KICK 1 and KICK 2. Each trial is expected to enroll approximately 400 patients, who will be randomized 1:1 to either oral difelikefalin 1 mg once daily or matching placebo. The study population will include adult patients suffering from moderate-to-severe pruritus with advanced CKD in Stages 4IV or 5, notV, including patients on dialysis. The primary endpoint will be the proportion of patients with a ≥4-point improvement at Week 12 from baseline in the worst-itch numerical rating scale, or WI-NRS,NRS after which patients will be re-randomized to either oral difelikefalin or placebo for 52-weeks. We expect to report top-line results from this program in the second half of 2024.

Oral difelikefalinDifelikefalin for the Treatment of Moderate-to-Severe Pruritus Associated with Atopic Dermatitis (AD)

AD is a chronic, pruritic inflammatory dermatosis that affects up to 25% of children and 2% to 5% of adults. Chronic pruritus is one of the defining features of AD. The itch is so common in AD that AD is often described as the itch that rashes. The point prevalence of chronic pruritus ranges between 87% to 100% in AD. According to a study published in Allergy in 2018, the point prevalence in adults in the U.S. is 4.9%, or approximately 12 million adults. Both quality of life and psychosocial well-being are known to negatively correlate with itch severity. The associated psychosocial morbidity of this distressing symptom includes sleep disruption, depression, agitation, anxiety, altered eating habits, reduced self-esteem and difficulty concentrating.

Additionally, AD patients can be segmented into groups based on the severity of their skin lesions as well as the severity of their itch. In a study published in Annals of Allergy, Asthma Immunology in 2021, it was found that nearly 25% of AD patients had mild-to-moderate lesions but still had severe pruritus. This “itch dominant” AD phenotype has a significant unmet medical need as their skin lesions have been controlled, but their severe itch has persisted. Most times, these patients have tried available agents (i.e., topical therapies, including corticosteroids, antihistamines) to control pruritus related to their AD unsuccessfully resulting in a significant patient population that needs a new oral agent for pruritus relief.

In April 2021, we announced top-line data from our Phase 2 KARE clinical trial. The KARE Phase 2 trial was a randomized, double-blind, placebo-controlled study designed to evaluate the efficacy and safety of oral difelikefalin for moderate-to-severe pruritus in 401 adult subjects with AD-aP. KARE enrolled 64% of patients characterized as mild-to-moderate AD (Body Surface Area, or BSA, <10%) and 36% falling into theas moderate-to-severe AD category (BSA>10%). Subjects were randomized to three dosage strengths of oral difelikefalin: 0.25 mg, 0.5 mg and 1 mg taken twice daily (BID) vs. matching placebo for 12 weeks followed by 4 weeks of an open-label active extension phase. A prespecified interim conditional power assessment was conducted after approximately 50% of the originally targeted patient number completed the designated 12-week treatment period. Based on the Independent Data Monitoring Committee’s recommendation, the sample size for each of the 0.5 mg dose and placebo groups were increased, taking the total trial size up by 28%.

KARE’s primary efficacy endpoint was change from baseline in the weekly mean of the daily 24-hour Itch NRS score at week 12 of the treatment period for the intent to treat, or ITT, population. Although no dose group met this endpoint, a statistically significant improvement from baseline was evident as early as week 1 for the 1 mg dose group, which was sustained through 75% of the treatment period.

In a prespecified analysis, a statistically significant change in the primary efficacy endpoint was observed in the mild-to-moderate (BSA<10%) AD patient population (p=0.036, All doses vs. placebo), which was evident at week 1 and sustained through the 12-week treatment period.

The key secondary endpoint for KARE was the assessment of the proportion of patients achieving an improvement from baseline of ≥4 points with respect to the weekly mean of the daily 24-hour Itch NRS score at week 12 (4-point Responder Analysis). No dose group met this endpoint for the ITT population.

A prespecified analysis by disease severity indicated a statistically significant improvement in the 4-point Responder Analysis in the mild-to-moderate (BSA<10%) AD patient population with 33% of difelikefalin-treated patients achieving a ≥4-point reduction in NRS at Week 12 vs. 19% in the placebo group for the 0.5 mg dose (p=0.046). All doses performed similarly (0.25 mg, 0.5 mg, and 1 mg) vs. placebo.

Oral difelikefalin was generally well-tolerated across all doses.

Oral difelikefalinDifelikefalin for the Treatment of Moderate-to-Severe Pruritus Associated with Notalgia Paresthetica (NP)

NP is a common, neurosensory condition caused by alteration and damage to thoracic spinal nerves and is characterized by chronic pruritus in the upper back. It is estimated that chronic pruritus affects up to 13% of the U.S. population. NP falls within the subcategory of chronic neuropathic pruritus which comprises approximately 8% of all cases of chronic pruritus. We estimate that approximately 650,000 adult patients with NP associated pruritus are in the care of a healthcare provider.

There are no FDA-approved treatments for NP. The management of NP is challenging and conventional treatments for pruritus, such as antihistamines and topical steroids, are largely ineffective.

In SeptemberJune 2022, we announced datapositive top-line results from ourthe proof-of-concept Phase 2 KOMFORT clinical trial. trial of oral difelikefalin for the treatment of pruritus in patients with NP.

KOMFORT was a Phase 2 randomized, double-blind, placebo-controlled trial designed to evaluate the efficacy and safety of oral difelikefalin for moderate-to-severe pruritus in 125 adult patients with NP and moderate-to-severe pruritus. Patients were randomized to receive oral difelikefalin 2 mg twice daily (BID) vs. matching placebo for eight weeks followed by a 4-week open-label active extension period and follow-up visit approximately 14 days after the last dose of the study drug.

Table of Contents

KOMFORT’s primary efficacy endpoint was the change from baseline in the weekly mean of the daily 24-hour worst itch NRS score at week 8 of the treatment period. Patients treated with oral difelikefalin achieved the primary endpoint (-4.0 difelikefalin vs. -2.4 placebo, p=0.001) with statistically significant improvement observed as early as WeekDay 1 and sustained through Week 8.

Other endpoints included a ≥4-point improvement in worst itch NRS, complete response in worst itch NRS, and safety assessments. A statistically significantly greater proportion of patients treated with oral difelikefalin achieved a ≥4-point improvement in worst itch NRS score at Week 8 vs. placebo (41% difelikefalin vs. 18% placebo, p=0.007). In addition, oral difelikefalin met the complete response endpoint, defined as a worst itch NRS score of 0 or 1 for 70% of the daily non-missing worst itch NRS scores for the week. At Week 8, a significantly greater proportion of patients receiving oral difelikefalin vs. placebo achieved a complete response (22% difelikefalin vs. 5% placebo, p<0.01).

Oral difelikefalin was generally well tolerated, with all AEs in difelikefalin-treated patients reported as mild or moderate in severity. Nausea, headache, dizziness, constipation, and increased urine output were more commonly reported in patients on difelikefalin.

We are scheduled to meetIn November 2022, we had a positive interaction with the FDA in November 2022leading to discuss next steps toward a potential pivotal program for oral difelikefalin in NP.

Oral difelikefalin for the Treatment of Chronic Liver Disease-Associated Pruritus (CLD-aP), including PBC

Pruritus develops in association with chronic liver diseases including hepatitis, liver cirrhosis, and PBC. It is estimated that approximately 6 million patients were diagnosed with CLD in 2019 in the U.S. and approximately 3 million patients received a prescription for an anti-pruritic agent. There are no FDA-approved therapies for pruritus associated with CLD, including PBC. Current antipruritic therapies, primarily antihistamines and corticosteroids as well as other therapies used off-label, are largely ineffective in treating the disease and/or can produce significant side effects.

We have been evaluating oral difelikefalin in PBC to establish a proof-of-concept in CLD-aP. It has been estimated that 70% of PBC patients experience pruritus.

In June 2019, we announced the initiation of a proof-of-concept Phase 2 trial of oral difelikefalin2/3 program for the treatment of chronic pruritus associated with NP. In February 2023, the results of our KOMFORT Phase 2 trial were published in the New England Journal of Medicine.

In the first quarter of 2023, we initiated a Phase 2/3 program for the treatment of moderate-to-severe pruritus in NP patients. The Phase 2/3 program for difelikefalin in NP will comprise two studies: KOURAGE 1 and KOURAGE 2. The KOURAGE 1 study will be composed of two parts: Part A and Part B.

KOURAGE 1 and KOURAGE 2 will be double-blind, placebo-controlled, 8-week studies with patients allowed to roll-over into open label 52-week extensions. Part A of KOURAGE 1, the dose finding portion of the trial, is expected to include 200 patients who will be randomized equally to four arms (0.25 mg BID, 1.0 mg BID, 2.0 mg BID, placebo

BID). At the end of the 8-week treatment period in Part A of KOURAGE 1, we expect to have an internal data read out targeted for the second half of 2024. This readout will provide key information, specifically the dose and the sample size to initiate Part B of KOURAGE 1 and KOURAGE 2. Part B and KOURAGE 2 will be identical in design. They will be double-blind, placebo-controlled, 8-week studies with patients randomized 1:1 to either difelikefalin or matching placebo. The difelikefalin dose is expected to be based on the results from Part A of KOURAGE 1. The primary endpoint will be the proportion of patients with hepatic impairment due to PBC. The Phase 2 multicenter, randomized, double-blind, placebo-controlled 16-week trial is designed to evaluate the safety and efficacy of 1 mg of oral difelikefalin taken twice daily vs. placebo in approximately 60 patients with PBC and moderate-to-severe pruritus. The primary efficacy endpoint is the changea ≥4-point improvement at Week 8 from baseline in the weekly mean of the daily 24-hour worst itch NRS score at week 16 of the treatment period. Secondary endpointsNRS.

The studies will include change from baseline in itch-related quality of life scores at the end of week 16 as assessed by the Skindex-10 and 5-D itch scales, as well as the assessment of proportion of patients achieving an improvement from baseline of ≥3 points with respect to the weekly mean of the daily 24-hour worst itch NRS score at week 16.

Based on slow enrollment due primarily to COVID-19, we made a strategic decision to discontinue and unblind the proof-of-concept Phase 2 clinical trial of oral difelikefalin for the treatment of pruritus inadult patients with PBC. The unblinded data showed no unexpected AEs. However, the low numberNP who have had chronic pruritus of patients (N=14) limits the ability to draw a meaningful conclusion regarding the efficacymoderate-to-severe intensity for ≥6 months (worst itch NRS change from baseline at 16 weeks: -3.8 difelikefalin vs. -3.0 placebo) of difelikefalin≥ 5).

We expect to release top-line results for both KOURAGE 1 Part B and KOURAGE 2 in this patient population. At this time, we plan to focus our resources on our nephrology and dermatology programs.the first half of 2026.

The Enteris License Agreement will expire on a country-by-country, licensed product-by-licensed product basis upon the later of (1) the expiration (or invalidation) of all valid claims in licensed patent rights that cover such product in such country, (2) the end of the calendar quarter in which generic competition (as defined in the Enteris License Agreement) occurs for such product in such country and (3) ten years from the first commercial sale of such product.

Patheon UK Limited (Patheon)

In July 2019, we entered into a Master Services Agreement, or MSA, with Patheon UK Limited, or Patheon. The MSA governs the general terms under which Patheon, or one of its affiliates, will provide non-exclusive manufacturing services to us for the drug products specified by us from time to time. Pursuant to the MSA, we have agreed to order from Patheon at least a certain percentage of our commercial requirements for a product under a related Product Agreement. Each Product Agreement that we may enter into from time to time will be governed by the terms of the MSA, unless expressly modified in such Product Agreement.

The MSA has an initial term ending December 31, 2023,2024, and will automatically renew after the initial term for successive terms of two years each if there is a Product Agreement in effect, unless either party gives notice of its intention to terminate the MSA at least 18 months prior to the end of the then current term.

Also in July 2019, we entered into two related Product Agreements under the MSA, one with each of Patheon and Patheon Manufacturing Services LLC, or Patheon Greenville, to govern the terms and conditions of the manufacture of

commercial supplies of difelikefalin injection, our lead product candidate. Pursuant to the Product Agreements, Patheon and Patheon Greenville will manufacture commercial supplies of difelikefalin injection at the Monza, Italy and Greenville, North Carolina manufacturing sites, respectively, from API supplied by us. Patheon and Patheon Greenville will be responsible for supplying the other required raw materials and packaging components, and will also provide supportive manufacturing services such as quality control testing for raw materials, packaging components and finished product.

We commenced our commercial launch of KORSUVA injection for the treatment of pruritus in adult patients undergoing hemodialysis in the U.S.United States in April 2022 following FDA approval of KORSUVA injection in August 2021. TheWe also commenced our commercial launch of Kapruvia in Europe in the EU commenced in September 2022third quarter of 2022. Commercial launches in Austria, Germany, Sweden, France, the Netherlands, Finland, and shortly thereafter in Germany. Launches inSwitzerland have commenced. We expect additional EU countries are planned incommercial launches to commence over the comingnext 12-18 months.

Revenue from sales of KORSUVA injection in future periods is subject to uncertainties and will depend on several factors, including the success of our and our commercial partners’ commercialization efforts in the U.S.,United States, the number of new patients adopting or switching to KORSUVA injection, patient retention and sustained demand, the number of physicians prescribing KORSUVA injection, the rate of monthly prescriptions, reimbursement from third-party payors including the U.S. government, the conversion of patients from our clinical trials to commercial customers, and market trends. More specifically, in December 2021, CMS granted TDAPA to KORSUVA injection in the anti-pruritic functional category. TDAPA went into effect on April 1, 2022, for a minimum of two years. CMS expressed in its written communication to us and Vifor, a continuing interest in engaging with the companies regarding potential post-TDAPA support to ensure all beneficiaries with ESRD have access to innovative products such as KORSUVA injection. However, there is no assurance that KORSUVA injection will be able to maintain its price established during the TDAPA period in the post-TDAPA timeframe, which could significantly impact our revenues in future periods. InOn June 2022,26, 2023, CMS issued a calendar year 2023the CY 2024 ESRD PPS proposed rule to update Medicare payment policies and rates for renal dialysis services which includedincluding a request for information, or RFI, to seek input on potential methodologies to add additional money through an add-on adjustmentproposed methodology for certainpost-TDAPA reimbursement for TDAPA drugs that enter the PPSdesignated products in an existing functional category.categories. The options includedproposed rule provides for additional funding per dialysis treatment outside the bundle rate for a 3-year post-TDAPA period starting immediately upon the expiration of the TDAPA period. CMS is expected to issue a final CY 2024 rule in the RFI, if proposedfourth quarter of 2023. There is no assurance that the final CY 2024 rule provides for sufficient funding to maintain or grow KORSUVA patient volume post the TDAPA period which could significantly impact our revenues in future periods.

Further, in November 2022, CMS published a CY 2023 ESRD PPS final rule that, among others, updated Medicare payment policies and ultimately approved through Noticerates for renal dialysis services. This final rule rebased and Comment Rulemaking, could resultrevised ESRD bundled market basket to a 2020 base year, updated the labor-related share, changed the ESRD PPS methodology for calculating the outlier threshold for adult patients, applied a permanent 5% cap on decreases in the provision of additional payments for KORSUVA injection post-TDAPA.

Table of Contents

Cost of Goods Sold (COGS)

Cost of goods soldCOGS includes costs related to sales of our commercial product, KORSUVA injection, to CSL Vifor. Costs related to the sales of KORSUVA injection are generally recognized upon receipt of shipment by CSL Vifor. Our COGS for KORSUVA injection include the cost of producing commercial product that correspond with commercial supply revenue, such as third-party supply and overhead costs, as well as certain period costs related to freight, packaging, stability, and quality testing. The related COGS for CSL Vifor associated with the net profit share arrangement as well as the marketing and distribution fee for the applicable period reduces our profit share revenue for the period.

In JanuaryDuring the three and six months ended June 30, 2023, we recorded commercial supply revenue of $1.4 million and $4.6 million, respectively, with associated COGS of $1.4 million and $4.0 million, respectively. During the six months ended June 30, 2022, we recorded commercial supply revenue of $2.3$4.8 million with no associated COGS of $2.1 million. Through February 2022, we had not recorded any COGS related to our commercial supply revenue, as all inventory costs were incurred prior to receipt of regulatory approval of KORSUVA injection and, accordingly, were expensed as incurred. In March 2022, we recorded commercial supply revenue of $2.5 million, with associated COGS of $2.1 million as these inventory costs were incurred subsequent to the receipt of regulatory approval of KORSUVA injection and, accordingly, were capitalized as inventory. DuringThere was no commercial supply revenue during the three months ended SeptemberJune 30, 2022, we recorded commercial supply revenue of $3.4 million, with associated COGS of $3.1 million.2022. We expect our COGS to increase as CSL Vifor generates additional sales of KORSUVA injection in the future.

Research and Development (R&D)

Our R&D expenses relate primarily to the development of difelikefalin. R&D expenses consist of expenses incurred in performing R&D activities, including compensation and benefits for full-time R&D employees, clinical trial and related clinical manufacturing expenses, third-party formulation expenses or milestone payments, fees paid to CROs and other consultants, stock-based compensation for R&D employees and consultants, and other outside expenses. Our R&D

50

Table of Contents

expenses also included expenses related to preclinical activities for our earlier stage programs in prior periods and may include such expenses in the future.

R&D costs are expensed as incurred. Non-refundable advance payments for goods or services to be received in the future for use in R&D activities are deferred and capitalized. The capitalized amounts are expensed as the related goods are delivered or the services are performed. Most of our R&D costs have been external costs, which we track on a program-by program basis. Our internal R&D costs are primarily compensation expenses for our full-time R&D employees. We do not track internal R&D costs on a program-by-program basis.

R&D activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. Based on our current development plans, we presently expect that our R&D expenses for 20222023 will be higher than 2021.2022. However, it is difficult to determine with certainty the duration and completion costs of our current or future nonclinical and clinical studies of our product candidates, or if, when or to what extent we will generate revenues from the commercialization and sale of any of our product candidates that obtain regulatory approval. We may never succeed in achieving regulatory approval for any of our product candidates.

The duration, costs and timing of clinical trials and development of our product candidates will depend on a variety of factors including, but not limited to:

per patient trial costs;
the number of patients that participate in the trials;
the number of sites included in the trials;
the countries in which the trial is conducted;

47

Table of Contents

the length of time required to enroll eligible patients;
the number of doses that patients receive;
the drop-out or discontinuation rates of patients;
potential additional safety monitoring or other studies requested by regulatory agencies;
the duration of patient follow-up; and
the efficacy and safety profile of the product candidate.

In addition, the probability of success for each product candidate will depend on numerous factors, including competition, manufacturing capability and commercial viability. We will determine which programs to pursue and how much to fund each program in response to the scientific and clinical success of each product candidate, as well as an assessment of each product candidate’s commercial potential.

General and Administrative (G&A)

General and administrative, or G&A, expenses consist primarily of salaries and other related costs, including stock-based compensation, for personnel in executive, finance, accounting, legal, business development, information technology, or IT, human resources, project management, alliance management, and procurement functions. Other costs include facility costs not otherwise included in R&D expenses, legal fees, insurance costs, investor relations costs, patent costs and fees for accounting and consulting services.

51

Table of Contents

We anticipate that our general and administrativeG&A expenses for 20222023 will be consistent with 20212022 to support our continued R&D activities and for our product candidates. These expenses will likely include costs related to the hiring of additional personnel, fees to outside consultants, lawyers, and accountants. In addition, if oral difelikefalin or any future product candidate obtains regulatory approval for marketing, we may incur expenses associated with building sales and marketing, commercial operations, and market access teams.

Our license agreements with CSL Vifor provide full U.S. commercialization rights of KORSUVA injection to CSL Vifor under profit-sharing arrangements. Under these profit-sharing arrangements, in consideration of CSL Vifor’s conduct of the marketing, promotion, selling and distribution of KORSUVA injection in the U.S.,United States, we pay a marketing and distribution fee to CSL Vifor based on the level of annual net sales. This fee as well as CSL Vifor’s COGS are deducted from product sales in calculating the net profits that are subject to the profit-sharing arrangement (see Note 11 of Notes to Condensed Financial Statements, Collaboration and Licensing Arrangements, in this Quarterly Report on Form 10-Q).

Other Income, Net

Other income, net consists of interest and dividend income earned on our cash, cash equivalents, and marketable securities, realized gains and losses on the sale of marketable securities and property and equipment, as well as accretion of discounts/amortization of premiums on purchases of marketable securities. In the event we record a credit loss expense on our available-for-sale debt securities, those expenses would be offset against other income.

Income Taxes

Historically, our benefit from income taxes related to state R&D tax credits exchanged for cash pursuant to the Connecticut R&D Tax Credit Exchange Program, which permits qualified small businesses engaged in R&D activities within Connecticut to exchange their unused R&D tax credits for a cash amount equal to 65% of the value of the exchanged credits.

For the three months ended SeptemberJune 30, 20222023 compared to the three months ended SeptemberJune 30, 2021,2022, the net$9.7 million increase in direct clinical trial costs and related consultant costswas primarily resulted from increases totaling $5.8 million, mainly fromdue to the increases in clinical trial spend related to our twothree late-stage oral difelikefalin Phase 3 programs. These increases were partially offset by decreases of $2.0 million, mainly from the Phase 2 efficacy trial for pruritus associated with AD-aP. The increase in other R&D operating expenses primarily resulted from the recognition of a $5.0 million milestone payment due to Enteris during the three months ended September 30, 2022.

For the nine months ended September 30, 2022 compared to the nine months ended September 30, 2021, the net increase in direct clinical trial costs and related consultant costs primarily resulted from increases totaling $13.1 million, mainly from increases in clinical trial spend related to our two oral difelikefalin Phase 3 programs, and other general costs associated with our oral programs. These increases were partially offset by decreases of $3.6 million, mainly fromrelated to the Phase 2 efficacy trial for pruritus associated with AD-aP.NP, and costs associated with our prior difelikefalin injection trials. The decrease in stock compensation expense is primarily related to lower grant date fair values for new option grants during the three months ended June 30, 2023, and lower stock compensation expense related to time-based restricted stock units that fully vested in February 2023. The $1.1 million increase in other R&D operating expenses was primarily resulted fromrelated to increases in payroll-related costs.

For the recognition of a $5.0 million milestone payment due to Enteris during the 2022 period assix months ended June 30, 2023 compared to the recognition of a $10.0six months ended June 30, 2022, the $11.9 million milestone paymentincrease in direct clinical trial costs was primarily due to Enteris during the 2021 period,increases in clinical trial spend related to our three late-stage oral difelikefalin programs. These increases were partially offset by decreases related to the Phase 2 efficacy trial for pruritus associated with NP, costs associated with our prior difelikefalin injection trials, and other general costs associated with our oral programs. The decrease in stock compensation expense is primarily related to lower grant date fair values for new option grants during the six months ended June 30, 2023, and lower stock compensation expense related to time-based restricted stock units that fully vested in February 2023.

Benefit from Income Taxes

Because our revenue in 2020 exceeded $70.0 million, weWe were not eligible to exchange our 2021 R&D tax credit for cash during the three and six months ended June 30, 2023 and 2022, therefore there was no benefit from income taxes for each of the three and ninesix months ended SeptemberJune 30, 2021.2023 and 2022. As of SeptemberJune 30, 2022,2023, we did not qualifyrecorded $0.7 million within income tax receivable which related to receive a refund of the 2022 credit, therefore no receivable or benefit from income taxes was recorded for the 2022 credit during the three and nine months ended September 30, 2022.2020 R&D credit.

We recognized a full valuation allowance against deferred tax assets at SeptemberJune 30, 20222023 and December 31, 2021.2022. The tax benefit related to the exercise of stock options is recognized as a deferred tax asset that is offset by a corresponding valuation allowance. As such, our effective tax rate is zero for each of the three and ninesix months ended SeptemberJune 30, 20222023 and 2021.2022.

Capital Requirements, Liquidity, and Capital Resources

Short-Term and Long-Term Cash Requirements

Our primary uses of capital have been, and we expect will continue to be, compensation and related expenses, third-party clinical R&D services, and clinical costs related to the oral difelikefalin program.

As of SeptemberJune 30, 2022,2023, we have no commitments for capital expenditures in either the short-term or long-term. The following discussion summarizes our current and long-term material cash requirements as of SeptemberJune 30, 2022,2023, which we expect to fund primarily with current unrestricted cash and cash equivalents and available-for-sale marketable securities:

(1)Operating lease obligations in 2023 relate to our Stamford operating leases entered into in December 2015, and amended in June 2020 and(which continue through December 2023.2023). Operating lease obligations in 2024 and beyond relate to our new lease entered into in May 2023 for our new principal executive offices, for which rent payments are expected to begin in late 2024. See Note 16 of Notes to Condensed Financial Statements, Commitments and Contingencies, in this Quarterly Report on Form 10-Q for details about our operating lease obligations.
(2)Based on our MSA with Patheon that we entered into in July 2019, we have a purchase capacity reservation through December 31, 2023. We expect the majority of this capacity reservation will be reimbursed in accordance with the supply agreement with CSL Vifor. See Note 16 of Notes to Condensed Financial Statements, Commitments and Contingencies, in this Quarterly Report on Form 10-Q for details about our MSA with Patheon. We have no other material non-cancelable purchase commitments with any other contract manufacturers or service providers, as we have generally contracted on a cancelable purchase order basis.
(3)We are required to maintain a stand-by letter of credit as a security deposit under our leases for office space in Stamford, Connecticut. Obligations in 2023 relate to our existing leases that terminate in December 2023.

As we anticipate revenue increasing in the short-term and long-term with the commercialization of KORSUVA injection and Kapruvia, our costs of manufacturing will also increase.

Based on the Enteris License Agreement that we entered into in August 2019, we are obligated to pay (1) milestone payments upon the achievement of certain development, regulatory and commercial milestones and (2) low-single digit royalty percentages on net sales of licensed products, subject to reductions in specified circumstances. As these milestone payments may or may not be achieved, and royalties may or may not be owed depending on our future commercial success. During the three months ended September 30, 2022, Enteris earned a $5.0 million milestone payment, which was subsequently paid in October 2022, and was included within accounts payable and accrued expenses on our condensed balance sheet as of September 30, 2022. As a result,success, there were no future potential payments that were considered cash requirements in the table above as of SeptemberJune 30, 2022.2023. During the three and six months ended June 30, 2023 and 2022, there were no milestone payments made to Enteris. See Note 16 of Notes to Condensed Financial Statements, Commitments and Contingencies, in this Quarterly Report on Form 10-Q for details about our Enteris License Agreement.

We do not have any other requirements or off-balance sheet arrangements that have or are reasonably likely to have a material current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, cash requirements or capital resources.

Since inception, we have incurred significant operating and net losses. We incurred net losses of $23.2$31.5 million and $1.0$4.2 million for the three months ended SeptemberJune 30, 20222023 and 2021,2022, respectively, and $55.1$58.1 million and $32.0 million for each of the ninesix months ended SeptemberJune 30, 2023 and 2022, and 2021.respectively. As of SeptemberJune 30, 2022,2023, we had an accumulated deficit of $535.9$624.4 million. Although we generated net income for the year ended December 31, 2020 as a result of a commercial license transaction, weWe expect to continue to incur significant expenses and operating and net losses in the foreseeable future, as we and our partner CSL Vifor expand the commercial launch of KORSUVA injection and Kapruvia and to develop and seek marketing approval for oral difelikefalin. However, we will not incur any material commercial costs on KORSUVA injection and Kapruvia due to the licensing agreement with CSL Vifor. Our financial results may fluctuate significantly from quarter to quarter and year to year, depending on the success of our commercialization efforts, timing of our clinical trials, the receipt of additional milestone payments, if any, under our licensing and collaborations with CSL Vifor, Maruishi and CKDP, the receipt of payments under any future collaborations and/or licensing agreements we may enter into, and our expenditures on other R&D activities.

We anticipate that our expenses will increase as we:

continue the development of oral difelikefalin for pruritus associated with AD, NDD-CKD,advanced CKD, and NP;
seek regulatory approvals for any product candidates that successfully complete clinical trials;
establish a sales, marketing and distribution infrastructure and scale up external manufacturing capabilities to commercialize any other products for which we may obtain regulatory approval;
maintain, expand and protect our global intellectual property portfolio;
hire additional clinical, quality control and scientific personnel; and
add operational, financial and management information systems and personnel, including personnel to support our drug development and potential future commercialization efforts.

The successful commercialization of KORSUVA injection and Kapruvia and the successful development of any of our other product candidates is highly uncertain. As such, at this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to successfully commercialize KORSUVA injection and Kapruvia, complete the development of I.V. difelikefalin, oral difelikefalin or our other current and future programs. We are also unable to predict

53

Table of Contents

when, if ever, we will generate any further material net cash inflows from difelikefalin. This is due to the numerous risks and uncertainties associated with developing medicines, including the uncertainty of:

successful enrollment in, and completion of clinical trials;
receipt of marketing approvals from applicable regulatory authorities;
establishing commercial manufacturing capabilities or making arrangements with third-party manufacturers;
obtaining and maintaining patent and trade secret protection and regulatory exclusivity for our product candidates;
launching commercial sales of the products, if and when approved, whether alone or in collaboration with others;
achieving meaningful penetration in the markets which we seek to serve; and

57

Table of Contents

obtaining adequate coverage or reimbursement by third parties, such as commercial payers and government healthcare programs, including Medicare and Medicaid.

A change in the outcome of any of these variables with respect to the development of I.V. difelikefalin, oral difelikefalin or any of our future product candidates would significantly change the costs and timing associated with the development of that product candidate. Further, the timing of any of the above may be impacted by the COVID-19 pandemic, introducing additional uncertainty.

Although commercialCommercial launch of KORSUVA injection began in the U.S.United States in April 2022, and commercial launch of Kapruvia has commenced in the EU commenced in September 2022 in Austria, Germany, Sweden, France, the Netherlands, and shortly thereafterFinland. In August 2022, as part of the Access Consortium, difelikefalin injection was approved in Germany, launchesSwitzerland under the brand name Kapruvia, as well as Singapore and Canada under the brand name KORSUVA. Commercial launch in additional EU countries are plannedSwitzerland has also commenced. Difelikefalin injection was also approved under the brand name KORSUVA in the comingUAE, Kwait, and Israel in January 2023, May 2023, and June 2023, respectively. We expect additional commercial launches to commence over the next 12-18 months. Our other product candidates are still in clinical development and since the outcome of these efforts is uncertain, we cannot estimate the actual amounts necessary to successfully complete the commercialization of KORSUVA injection and Kapruvia and the development and commercialization of our other product candidates or whether, or when, we may achieve profitability. Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity or debt financings and collaboration arrangements, including our existing licensing and collaboration agreements with CSL Vifor, Maruishi and CKDP.

We will require additional capital beyond our current balances of cash and cash equivalents and available-for-sale marketable securities and anticipated amounts as described above, and this additional capital may not be available when needed, on reasonable terms, or at all, and ourall. Our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the continuing disruptions to and volatility in the credit and equity markets in the U.S.United States and worldwide, resultingincluding impacts from the COVID-19 pandemic and its variants andor future public health crises, geopolitical tensions, such as Russia’s incursion intothe ongoing military conflict between Russia and Ukraine which resulted in a global slowdown of economic activity,and related sanctions against Russia, decades-high inflation, rising interest rates, uncertainty and liquidity concerns in the broader financial services industry, such as those caused by certain recent banking failures, and a potential recession.recession in the United States. If we are not able to do so, we could be required to postpone, scale back or eliminate some, or all, of these objectives. To the extent that we raise additional capital through the future sale of equity or convertible debt, the ownership interest of our stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our existing common stockholders. If we raise additional funds through the issuance of debt securities, these securities could contain covenants that would restrict our operations. If we raise additional funds through collaboration arrangements in the future, we may have to relinquish valuable rights to our technologies, future

revenue streams or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our drug development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Sources of Liquidity

Since our inception to date, we have raised an aggregate of $881.1$897.5 million to fund our operations, including (1) net proceeds of $446.3 million from the sale of shares of our common stock in five public offerings, including our initial public offering; (2) proceeds of $73.3 million from the sale of shares of our convertible preferred stock and from debt financings prior to our initial public offering; (3) payments of $248.1$255.2 million under our license and supply agreements (including commercial supply sales and royalty payments), primarily with CSL Vifor, Vifor International, Maruishi, CKDP, and an earlier product candidate for which development efforts ceased in 2007; (4) net profit-sharing revenueour share of $15.4 million fromthe profit generated by KORSUVA injection sales of KORSUVA injection to third parties by Vifor;$24.7 million; and (5) net proceeds of $98.0 million from the purchase of our common stock in relation to the license agreements with CSL Vifor and Vifor International (see Note 11 of Notes to Condensed Financial Statements, Collaboration and Licensing Agreements, in this Quarterly Report on Form 10-Q).

In order to fund our future operations, including our planned clinical trials, on March 1, 2022, we filed a universal shelf registration statement, or the Shelf Registration Statement, which provides for aggregate offerings of up to $300.0 million of common stock, preferred stock, debt securities, warrants or any combination thereof. The Shelf Registration Statement was declared effective by the Securities and Exchange Commission on May 11, 2022. The securities registered under the Shelf Registration Statement include $154.5 million of unsold securities that had been registered under our previous Registration Statement on Form S-3 (File No. 333-230333) that was declared effective on April 4,

58

Table of Contents

2019. We believe that our Shelf Registration Statement will provide us with the flexibility to raise additional capital to finance our operations as needed.

We may offer additional securities under our Shelf Registration Statement from time to time in response to market conditions or other circumstances if we believe such a plan of financing is in the best interests of our stockholders. On March 1, 2022, we entered into an open market sales agreement, or the Sales Agreement, with Jefferies LLC, as sales agent, pursuant to which we may, from time to time, issue and sell common stock with an aggregate value of up to $80.0 million in an at-the-market offering. Jefferies is acting as sole sales agent for any sales made under the Sales Agreement for a 3% commission on gross proceeds. The common stock will be sold at prevailing market prices at the time of the sale, and, as a result, prices may vary. Unless otherwise terminated earlier, the Sales Agreement continues until all shares available under the Sales Agreement have been sold. No shares were sold under the Sales Agreement during the ninethree and six months ended SeptemberJune 30, 2023 and 2022.

We may offer additional securities under our Shelf Registration Statement from time to time in response to market conditions or other circumstances if we believe such a plan of financing is in the best interests of our stockholders.

Under Vifor Agreement No. 1, we are eligible to receive commercial milestone payments in the aggregate of up to $240.0 million upon the achievement of certain sales-based milestones. In October 2021, we received a $50.0 million milestone payment from Vifor International in exchange for the issuance of 3,282,391 shares of our common stock to Vifor International as a result of the regulatory approval of KORSUVA injection in August 2021. As of September 30, 2022,the date of this filing, we have received $50.0 million of regulatory milestones from Vifor International.

Under Vifor Agreement No. 2, we are eligible to receive commercial milestone payments in the aggregate of up to $440.0 million, all of which are sales-related. We are also eligible to receive tiered double-digit royalty payments based on annual net sales, as defined in Vifor Agreement No. 2, of difelikefalin injection in the licensed territories. In June 2022, we received a $15.0 million milestone payment from Vifor Fresenius Medical Care Renal Pharma Ltd. as a result of the regulatory approval of Kapruvia by the European Commission in April 2022. In October 2021, we received a $15.0 million milestone payment from Vifor Fresenius Medical Care Renal Pharma Ltd. as a result of the regulatory approval of KORSUVA injection in August 2021. As of September 30, 2022,the date of this filing, we have received $30.0 million of regulatory milestones from Vifor.Vifor Fresenius Medical Care Renal Pharma Ltd.

Under the Maruishi Agreement, we are also potentially eligible to earn up to an aggregate of $6.0 million in clinical development milestones and $4.5 million in regulatory milestones, before any foreign exchange adjustment, as well as

tiered royalties, with percentages ranging from the low double digits to the low twenties, based on net sales of products containing difelikefalin in Japan, if any, and share in any sub-license fees. In May 2021, we received a $2.0 million milestone payment ($1.9 million after contractual foreign currency exchange adjustments) for Maruishi’s first initiation of a Phase 3 trial for uremic pruritus in Japan in January 2021. As of September 30, 2022,the date of this filing, we have received $4.5 million (before contractual foreign currency exchange adjustments) of clinical development and regulatory milestone from Maruishi.

Under the CKDP Agreement, we are potentially eligible to earn up to an aggregate of $2.3 million in clinical development milestones and $1.5 million in regulatory milestones, before South Korean withholding tax, as well as tiered royalties with percentages ranging from the high single digits to the high teens, based on net sales of products containing difelikefalin in South Korea, if any, and share in any sub-license fees. As of September 30, 2022,the date of this filing, $2.3 million (before South Korean withholding tax) of development and regulatory milestones have been received under the CKDP Agreement.

In December 2021, CMS granted TDAPA designation to KORSUVA injection in the anti-pruritic functional category. TDAPA went into effect on April 1, 2022, for a minimum of two years.

Commercial launch has also commenced in AustriaSwitzerland, and shortly thereafter in Germany andwe expect additional commercial launches in additional EU countries are planned into commence over the comingnext 12-18 months.

Our ability to earn these payments and their timing is dependent upon the outcome of I.V. and oral difelikefalin development activities and successful commercialization of KORSUVA injection.injection and Kapruvia. However, our receipt of any further such amounts is uncertain at this time and we may never receive any more of these amounts.

Outlook

We expect that our current unrestricted cash and cash equivalents and available-for-sale marketable securities, including collaborative revenue from our share of the profit from KORSUVA injection, will be sufficient to fund our currently anticipated operating plan intofor at least the first half of 2024. This guidance assumes KORSUVA injection revenue profit share contribution consistent with what we have reported for the quarter ended September 30, 2022.next 12 months. Our anticipated operating expenses include contractually committed costs as well as non-contractually committed clinical trial costs for trials that may be delayed or not initiated and other non-committed controllable costs. Because the process of testing product candidates in clinical trials is costly and the timing of progress in these trials is uncertain, it is possible that the assumptions upon which we have based this estimate may prove to be wrong, and we could use our capital resources sooner than we presently expect.

Critical Accounting Estimates

The preparation of our condensed financial statements and related disclosures in conformity with U.S. GAAP and our discussion and analysis of financial condition and results of operations require us to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances at the time such estimates are made. Actual results and outcomes may differ materially from our estimates, judgments, and assumptions. We periodically review our estimates in light of changes in circumstances, facts, and experience. The effects of material revisions in estimates are reflected in the condensed financial statements prospectively from the date of the change in estimate. Note 2 of Notes to Financial Statements, Summary of Significant Accounting Policies, in our Annual Report on Form 10-K for the year ended December 31, 20212022, or Annual Report, describes the significant accounting policies and methods used in the preparation of our condensed financial statements.

We define our critical accounting estimates as those subjective estimates and judgments about matters that are uncertain and are likely to have a material impact on our financial condition and results of operations as well as the specific manner in which we apply U.S. GAAP.

During Our critical accounting policies that require significant judgments and estimates are more fully described under the three months ended September 30, 2022, there wereheading “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates” in our Annual Report and in Note 2 to our audited financial statements contained in our Annual Report. There have been no significant changes to our critical accounting policies that require significant judgments and estimates from those describeddisclosed in our Annual Report on Form 10-K for the year ended December 31, 2021, other than our net profit-sharing revenue from the sale of KORSUVA injection to third parties in the U.S. by Vifor. This estimate is

If we do not receive timely and accurate information or incorrectly estimate activity levels associated with the profit share arrangement at a given point in time, we could be required to record adjustments in future periods (see Note 2 of Notes to Condensed Financial Statements, Basis of Presentation, in this Quarterly Report on Form 10-Q).Report.

Item 3.Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk

As of SeptemberJune 30, 2022,2023, we invested a majority of our cash reserves in a variety of available-for-sale marketable securities, including investment-grade debt instruments, principally corporate bonds, commercial paper, municipal bonds and direct obligations of the U.S. government and U.S. government-sponsored entities, and in cash equivalents. See Note 3 of Notes to Condensed Financial Statements, Available-for-Sale Marketable Securities, in this Quarterly Report on Form 10-Q for details about our available-for-sale marketable securities.

As of SeptemberJune 30, 2022,2023, we had invested $136.7$43.5 million of our cash reserves in such marketable securities. Those marketable securities included $136.7$43.5 million of investment grade debt instruments with a yield of approximately 1.86%1.01% and maturities through November 2024. As of December 31, 2021,2022, we had invested $223.3$93.0 million of our cash reserves in such marketable securities. Those marketable securities included $223.3$93.0 million of investment grade debt instruments with a yield of approximately 0.28%2.01% and maturities through November 2024.

We maintain an investment portfolio in accordance with our investment policy, which includes guidelines on acceptable investment securities, minimum credit quality, maturity parameters, and concentration and diversification.

58

Table of Contents

The primary objectives of our investment policy are to preserve principal, maintain proper liquidity and to meet operating needs. Our investments are subject to interest rate risk and will decrease in value if market interest rates increase. However, due to the conservative nature of our investments and relatively short duration, we do not believe we are materially exposed to changes in interest rates related to our investments. As a result, we do not currently use interest rate derivative instruments to manage exposure to interest rate changes.

Duration is a sensitivity measure that can be used to approximate the change in the fair value of a security that will result from a change in interest rates. Applying the duration model, a hypothetical 100 basis point, or 1%, increase in interest rates as of SeptemberJune 30, 20222023 and December 31, 2021,2022, would have resulted in immaterial decreases in the fair values of our portfolio of marketable securities at those dates.

Credit Quality Risk

Although our investments are subject to credit risk, our investment policy specifies credit quality standards for our investments and limits the amount of credit exposure from any single issue, issuer or type of investment. Nonetheless, deterioration of the credit quality of an investment security subsequent to purchase may subject us to the risk of not being able to recover the full principal value of the security. As of June 30, 2023 and December 31, 2022, the aggregate unrealized losses on our available-for-sale marketable securities were $0.7 million and $1.7 million, respectively. For each of the three and ninesix months ended SeptemberJune 30, 20222023 and 2021,2022, we did not record any charges to credit loss expense for our available-for-sale securities. Refer to Note 3 of Notes to Condensed Financial Statements, Available-for-Sale Marketable Securities, in this Quarterly Report on Form 10-Q.

As of SeptemberJune 30, 2023 and December 31, 2022, we had $9.6 million in Accountsaccounts receivable, net - related party relating tofrom CSL Vifor of $10.1 million and $3.3 million, respectively, primarily for our profit-sharing revenue earned from salesshare of the profit generated by KORSUVA injection in the U.S. by Vifor andsales, commercial supply of KORSUVA injection to Vifor during the three months ended September 30, 2022.revenue, and royalty revenue. We did not identify anybelieve that credit risksrisk associated with our licensing partnerCSL Vifor duringis not significant. We review the three months ended September 30, 2022. As a result, weneed for an allowance for credit losses for any receivable based on various factors including payment history and historical bad debt experience. We had an insignificant allowance for credit losses as of SeptemberJune 30, 2022. As of2023 and December 31, 2021, we did not have a material balance of receivables.2022.

Item 1.Legal Proceedings

From time to time, we may become subject to arbitration, litigation or claims arising in the ordinary course of business. We are not currently a party to any arbitration or legal proceeding that, if determined adversely to us, would have a material adverse effect on our business, operating results or financial condition. The results of any future claims or proceedings cannot be predicted with certainty, and regardless of the outcome, litigation can have an adverse impact on us because of defense and litigation costs, diversion of management resources, and other factors.

We may disclose changes to risk factors or disclose additional factors from time to time in our future filings with the year ended December 31, 2021.SEC. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business operations. There have been no material changes to our risk factors as presented in our Annual Report on Form 10-K for the year ended December 31, 2022, other than the risk factorsfactor set forth below:

Risks Related to Legal and Compliance Matters

If the government or other third-party payers fail to provide coverage and adequate reimbursement and payment rates for KORSUVA injection or Kapruvia or any of our other current or future product candidates, if any, or if providers choose to use therapies that are less expensive, our revenue and prospects for profitability will be limited.

In both U.S. and international markets, sales of KORSUVA injection, Kapruvia and our future products (if approved) will depend in part upon the availability of coverage and reimbursement from third-party payers. Such third-party payers include government health programs such as Medicare and Medicaid in the U.S.,United States, managed care providers, private health insurers and other organizations. Coverage decisions may depend upon clinical and economic standards that disfavor new drug products when more established or lower cost therapeutic alternatives are already available or subsequently become available. Assuming coverage is approved, the resulting reimbursement payment rates might not be adequate. In the U.S.,United States, KORSUVA injection for the treatment of pruritus in adult hemodialysis patients is expected to be designated as a component of the government’s bundled reimbursement for end stage renal disease treatment after the expiration of the TDAPA period.

On October 31, 2019, CMS issued a final rule that revises payment policies and rates under the ESRD PPS for renal dialysis services furnished to beneficiaries on or after January 1, 2020. The final rule also updates the TDAPA. In the final rule, CMS revised ESRD PPS eligibility to focus on innovative drugs and excluded certain drugs from being eligible for the TDAPA. CMS will pay the revised TDAPA adjustment, which is called the Transitional Add-on Payment Adjustment for New and Innovative Equipment and Supplies , or TPNIES, for equipment and supplies that: (1) have been designated by CMS as a renal dialysis service, (2) are new, meaning granted marketing authorization by FDA on or after January 1, 2020, (3) are commercially available by January 1 of the particular calendar year, meaning the year in which the payment adjustment would take effect, (4) have a HCPCS application submitted in accordance with the official Level II HCPCS coding procedures by September 1 of the particular calendar year, (5) are innovative, meaning they meet the substantial clinical improvement criteria specified in the Inpatient Prospective Payment System regulations and related guidance, and (6) are not capital-related assets. TDAPA went into effect on April 1, 2022, for a minimum of two years, for KORSUVA injection. However, there is no assurance that KORSUVA injection will be able to maintain its price established in the TDAPA period in the post-TDAPA timeframe.

On November 2, 2020, CMS issued a final rule outlining its payment policies and rates under the ESRD PPS for the 2021 calendar year. In addition to the annual technical updates to the ESRD PPS, the final rule, among other things,

61

Table of Contents

expands eligibility under the TPNIES. In particular, the final rule provided for biannual coding cycles for new HCPCS Level II code applications, revised the definition of “new” to be three (3) years beginning on the date of FDA marketing authorization, and expanded eligibility under the TPNIES to include certain home dialysis capital-related assets.

64

Table of Contents

Additionally, in October 2021, CMS issued a final rule that updates the ESRD PPS for calendar year 2022. Further, on June 28, 2022, CMS published ain its Calendar Year 2023 ESRD PPS proposed rule, that would, among others, update Medicare payment policies and rates for renal dialysis services. This proposed rule would rebase and revise ESRD bundled market basket to a 2020 base year, update the labor-related share, change the ESRD PPS methodology for calculating the outlier threshold for adult patients, apply a permanent 5% cap on decreases in the ESRD PPS wage index, and increase the wage index floor. In the proposed rule, CMS also issued a request for information, or RFI, to seek input on potential methodologies to add additional money through an add-on adjustment methodology for certain TDAPA drugs that enter the prospective payment system in an existing functional category. The options included in the RFI, if proposed and ultimately approved through Notice and Comment Rulemaking, could result in the provision of additional payments for KORSUVA injection post-TDAPA. Further, on November 7, 2022, CMS published a Calendar Year 2023 ESRD PPS final rule that will, among others, update Medicare payment policies and rates for renal dialysis services. This final rule rebases and revises ESRD bundled market basket to a 2020 base year, updates the labor-related share, changes the ESRD PPS methodology for calculating the outlier threshold for adult patients, applies a permanent 5% cap on decreases in the ESRD PPS wage index, and increases the wage index floor. Also in the final rule, with regard to the RFI in the June 2022 proposed rule, CMS noted that most commenters expressed support for an add-on payment adjustment for new renal dialysis drugs to improve patient access to innovative drugs and that CMS intends to take the received comments into consideration during potential future policy development. As this is a proposed rule,an RFI, these provisions have not been proposed or implemented as a rule and there is no guarantee that CMS will implement this rule as currently drafted or will formally propose a change in policy in the form presented in the RFI. Our failureOn June 26, 2023, CMS issued the Calendar Year 2024 ESRD PPS proposed rule to maintain coverageupdate Medicare payment policies and adequaterates for renal dialysis services including a proposed methodology for post-TDAPA reimbursement for KORSUVA injectionTDAPA designated products in existing functional categories. The proposed rule provides for additional funding per dialysis treatment outside the bundle rate for a 3-year post-TDAPA period starting immediately upon the expiration of the TDAPA period. CMS is expected to issue a final Calendar Year 2024 rule in the post-TDAPA timeframe could affect our ability to commercialize KORSUVA injection successfully and could impact our profitability, resultsfourth quarter of operations, financial condition, and prospects.2023. There are no assurances that provisions, including any add-on payments after the expiration of the TDAPA period, contained in the Calendar Year 2024 proposed rule will be included in the Calendar Year Final Rule.

Additionally, many U.S. hospitals receive a fixed reimbursement amount per procedure for certain surgeries and other treatment therapies they perform, or a pre-determined rate for all hospital inpatient care provided as payment in full. Because, in these instances, the amount of reimbursement that such providers receive may not be based on the actual expenses the provider incurs, providers may choose to use therapies which are less expensive when compared to our product candidates. Accordingly, KORSUVA injection or any of our other current or future product candidates, if approved, will face competition from other therapies and drugs for these limited provider financial resources. We may need to conduct post-marketing studies in order to demonstrate the cost-effectiveness of any future products to the satisfaction of hospitals, other target customers and their third-party payers. Such studies might require us to commit a significant amount of management time and financial and other resources. Our future products might not ultimately be considered cost-effective. Third-party coverage and adequate reimbursement might not be available to enable us to maintain price levels sufficient to realize an appropriate return on investment in product development.

Third-party payers, whether U.S. or international, or governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare costs. In addition, in the U.S.,United States, no uniform policy of coverage and reimbursement for drug products exists among third-party payers. Therefore, coverage and reimbursement for drug products can differ significantly from payer to payer. Further, we believe that future coverage and reimbursement will likely be subject to increased restrictions both in the U.S. and international markets. Third-party coverage and reimbursement for our products or product candidates for which we receive regulatory approval may not be available or adequate in either the U.S. or international markets, which could have a negative effect on our business, results of operations, financial condition, and prospects.

Risks Related to Employee Matters and Managing Growth

If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements on a timely basis could be impaired.

We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, the Sarbanes-Oxley Act of 2002 and the rules and regulations of The Nasdaq Global Market. Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, we are required to perform system and process evaluation and testing of our internal control over financial reporting to allow our management to report on the effectiveness of our internal control over financial reporting and we have also been required to have our independent registered public accounting firm issue an opinion on the effectiveness of our internal control over financial reporting on an annual basis as a large accelerated filer. However, based on our public float as of June 30, 2022, we expect to qualify as a non-accelerated filer at the end of this year, which would allow us to forgo the auditor attestation requirement for the fiscal year ending December 31, 2022. However, we have determined to voluntarily comply with the auditor attestation requirement for the fiscal year ended December 31, 2022.

During the evaluation and testing process, if we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal control over financial reporting is effective. Further,

65

Table of Contents

we may in the future discover weaknesses in our system of internal financial and accounting controls and procedures that could result in a material misstatement of our financial statements. For example, beginning in April 2022, we began recognizing profit-sharing revenue from the sale of KORSUVA injection in the U.S. by Vifor under ASC 606. We are dependent on Vifor for timely and accurate information regarding the net revenues from sales of KORSUVA injection in the U.S. in accordance with ASC 606 to accurately report our results of operations. If we do not receive timely and accurate information or incorrectly estimate activity levels associated with the profit share arrangement at a given point in time, we could be required to record adjustments in future periods. Moreover, our internal controls over financial reporting will not prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected. Moreover, we are aware that the remote working arrangements implemented in connection with the COVID-19 pandemic potentially present additional areas of risk, including cyber, privacy and productivity risks, and we are carefully monitoring any impact to our internal controls and procedures.

If we are unable to assert that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable to express an opinion on the effectiveness of our internal control over financial reporting, investors could lose confidence in the reliability of our financial statements, the market price of our stock could decline and we could be subject to sanctions or investigations by The Nasdaq Global Market, the SEC or other regulatory authorities.
