Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
NATURE OF BUSINESS | NATURE OF BUSINESS Organization Akebia Therapeutics, Inc., referred to as Akebia or the Company , was incorporated in the State of Delaware in 2007 and became a public company in 2014. Akebia is a fully integrated commercial-stage biopharmaceutical company committed to addressing patients' unmet needs. The Company's purpose is to better the life of each person impacted by kidney disease. The Company has two products approved by the Food and Drug Administration, or FDA , in the United States, or U.S. , Vafseo® (vadadustat) is an oral hypoxia-inducible factor prolyl hydroxylase, or HIF-PH, inhibitor. Vafseo (vadadustat) Tablets were approved in the U.S. on March 27, 2024 for the treatment of anemia due to chronic kidney disease, or CKD , in adults who have been receiving dialysis for at least three months. The Company is launching Vafseo in the U.S. Auryxia ® (ferric citrate) is marketed for two indications: (i) the control of serum phosphorus levels in adult patients with dialysis dependent chronic kidney disease, or DD-CKD , and (ii) the treatment of iron deficiency anemia, or IDA, in adult patients with non-dialysis dependent chronic kidney disease, or NDD-CKD . Auryxia will lose exclusivity in the U.S. in March 2025. Vafseo is also approved for the treatment of symptomatic anemia associated with CKD in the European Economic Area, or EEA , the United Kingdom, or the UK , Switzerland, Australia, South Korea and Taiwan in adult patients on chronic maintenance dialysis and in Japan for adult dialysis-dependent and non-dialysis patients. Vafseo is marketed and sold by the Company's collaboration partners in certain countries. Ferric citrate is also approved in Japan, and is marketed and sold by the Company's collaboration partner, as an oral treatment for the improvement of hyperphosphatemia in patients with CKD, including DD-CKD and NDD-CKD, and for the treatment of adult patients with IDA under the trade name Riona (ferric citrate hydrate). Since its inception, the Company has devoted most of its resources to research and development, or R&D , including its preclinical and clinical development activities, commercializing Auryxia and providing general and administrative support for these operations. The Company began recording revenue from the U.S. sales of Auryxia and revenue from sublicensing rights to Auryxia in Japan from the Company’s Japanese partners, Japan Tobacco, Inc. and its subsidiary Torii Pharmaceutical Co., Ltd., collectively, JT and Torii , in 2018. In addition, the Company continues to explore additional development opportunities to expand its pipeline and portfolio of novel therapeutics. As of June 30, 2024, the Company had cash and cash equivalents of approximately $39.5 million. Based on its current operating plan, the Company believes that its cash resources and the cash the Company expects to generate from product, royalty, supply and license revenues will be sufficient to fund its current operating plan for at least twelve months from the filing of this Quarterly Report on Form 10-Q, or Form 10-Q . However, if the Company’s operating performance deteriorates significantly from the levels expected in the Company’s operating plan, it would affect the Company’s liquidity and its ability to continue as a going concern in the future. The Company expects to finance future cash needs through product and license, collaboration and other revenue, including royalties and revenue from supply agreements. If the Company believes its resources are insufficient to satisfy its liquidity requirements, it may seek to sell public or private equity, enter into new debt transactions, explore potential strategic transactions, consider other cash-generating or saving measures or a combination of these approaches or other strategic alternatives. There can be no assurance that the current operating plan will be achieved in the time frame anticipated by the Company or that its cash resources will fund its operating plan for the period of time anticipated by the Company, or that additional funding will be available on terms acceptable to the Company, or at all. |
SUMMARY OF SIGNIFICANT ACCOUNTI
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 6 Months Ended |

Accounting Policies [Abstract] | |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Company's significant accounting policies are disclosed in the audited consolidated financial statements for the year ended December 31, 2023, and notes thereto, which are included in the Company's Annual Report on Form 10-K, that was filed with the Securities and Exchange Commission, or SEC , on March 14, 2024, or the 2023 Form 10-K . Since the date of those financial statements, there have been no material changes to the Company's significant accounting policies. In the opinion of management, all adjustments, consisting of normal recurring accruals and revisions of estimates, considered necessary for a fair presentation of the unaudited condensed consolidated financial statements have been included. Interim results for the three and six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2024 or any other future period. The Company has experienced seasonality from quarter to quarter. In general, the first quarter usually has lower revenues than the preceding fourth quarter, the second and third quarters have higher revenues than the first quarter, and the fourth quarter revenues are the highest in the year. Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the U.S., or GAAP . Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification, or ASC , and Accounting Standards Update, or ASU, of the Financial Accounting Standards Board, or FASB . The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in the consolidated financial statements herein. Certain monetary amounts, percentages, and other figures included elsewhere in these unaudited condensed consolidated financial statements have been subject to rounding adjustments. Accordingly, figures shown as totals in certain tables may not be the arithmetic aggregation of the figures that precede them, and figures expressed as percentages in the text may not total 100% or, as applicable, when aggregated may not be the arithmetic aggregation of the percentages that precede them. Use of Estimates The preparation of financial statements in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenue and expenses, classification of the expenses, assets and liabilities and the disclosure of contingent assets and liabilities as of and during the reported period. On an ongoing basis, management evaluates its estimates. Management bases its estimates and assumptions on historical experience when available and on various factors, including expected business and operational changes, sensitivity and volatility associated with the assumption that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of the assets and liabilities that are not readily apparent from other sources. In certain circumstances, management must apply significant judgment in this process. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes, and management selects an amount that falls within that range of reasonable estimates. Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period they become known. Significant estimates and judgments reflected in these unaudited condensed consolidated financial statements include, but are not limited to: accrued expenses, other long-term liabilities, product revenues, including various rebates, returns and reserves related to product sales, inventories, classification of expenses between cost of goods sold, R&D and selling, general and administrative, long-term assets, including the Company's right-of-use assets, intangible asset and goodwill. Cash, Cash Equivalents and Restricted Cash In determining its cash, cash equivalents and restricted cash, the Company considers only those highly liquid investments, readily convertible to cash within 90 days from the date of purchase to be cash equivalents. As of June 30, 2024, cash and cash equivalents primarily included cash on hand. Restricted cash represents amounts required to secure the outstanding letter of credit in connection with the Company’s office and laboratory space in Cambridge, Massachusetts, or the Cambridge Lease . Restricted cash is included in “other long-term assets” in the consolidated balance sheets. The following table reconciles cash, cash equivalents and restricted cash reported within the Company's consolidated balance sheets to the total amounts showing in the consolidated statements of cash flows: (in thousands) June 30, 2024 December 31, 2023 Cash and cash equivalents $ 39,499 $ 42,925 Restricted cash included in other long-term assets 1,668 1,654 Total cash, cash equivalents and restricted cash $ 41,167 $ 44,579 Concentration of Credit Risk Cash, cash equivalents and accounts receivable are the only financial instruments that potentially subject the Company to concentrations of credit risk. The Company maintains cash accounts principally at two financial institutions in the U.S., which at times, may exceed the Federal Deposit Insurance Corporation's limits. The Company has not experienced any losses from cash balances in excess of the insurance limit. The Company's management does not believe the Company is exposed to significant credit risk at this time due to the financial condition of the financial institutions where its cash is held. The Company makes judgments as to its ability to collect outstanding receivables and provides an allowance for receivables when collection becomes doubtful. Provisions are made based upon a specific review of all significant outstanding receivables and the overall quality and age of those invoices not specifically reviewed as well as historical payment patterns and existing economic factors. The Company believes that credit risks associated with its customers and collaboration partners are not significant. The Company's allowance for credit losses was $0.2 million and $1.0 million as of June 30, 2024 and December 31, 2023, respectively. For the six months ended June 30, 2024, net recoveries were $0.2 million, inclusive of an incremental allowance for credit losses of $0.2 million for the three months ended June 30, 2024. Write-offs were $0.6 million for the three and six months ended June 30, 2023. Manufacturing and Distribution Risk The Company is dependent on third-party manufacturers, logistics companies and distributors to supply products for commercial activities associated with its product and product candidates, as applicable. In particular, the Company relies and expects to continue to rely on a small number of manufacturers to supply it with its requirements for the active pharmaceutical ingredients and formulated drugs related to the Company's product and product candidate activities. These activities, including the commercialization of Auryxia and Vafseo, could be adversely affected by a significant interruption in the supply of active pharmaceutical ingredients and formulated drugs or distribution of finished product to the market. Recent Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures . ASU 2023-07 requires disclosure of significant segment expenses that are regularly provided to the chief operating decision maker, or CODM, and included within the segment measure of profit or loss, an amount and description of its composition for other segment items to reconcile to segment profit or loss, and the title and position of the entity’s CODM. ASU 2023-07 will be applied retrospectively and is effective for annual reporting periods in fiscal years beginning after December 15, 2023, and interim reporting periods in fiscal years beginning after December 31, 2024. The Company is currently reviewing the impact that the adoption of ASU 2023-07 may have on its consolidated financial statements and disclosure. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures . ASU 2023-09 requires public companies to annually (i) disclose specific categories in the rate reconciliation and (ii) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). ASU 2023-09 will be effective for the annual reporting periods in fiscal years beginning after December 15, 2024. The Company is currently evaluating ASU 2023-09 and does not expect it to have a material effect on the Company’s consolidated financial statements. |

On the Tranche B Closing Date, the Company drew $7.5 million, after deducting debt issuance costs, fees and expenses. The BlackRock Term Loan Facility had an initial maturity date of March 31, 2025, which was automatically extended to January 29, 2028, after the Company received FDA approval for Vafseo, or the BlackRock Maturity Date . The Company is required to make interest-only payments until December 31, 2026, or the BlackRock Interest Only Period , after which the Company will begin paying equal monthly principal on the first calendar day of each month. In the event of certain prespecified events, the repayment schedule will be accelerated. The Term Loan Facility will accrue interest at a floating annual rate equal to the sum of (i) term Secured Overnight Financing Rate SOFR , for a tenor of one month (subject to a floor of 4.25% per annum) plus (ii) a margin of 6.75% per annum (subject to an overall cap of 15.00% per annum on the all-in interest rate).

Other Liabilities Disclosure [Abstract] | |
DEFERRED REVENUE, REFUND LIABILITY AND LIABILITY RELATED TO SALE OF FUTURE ROYALTIES | DEFERRED REVENUE, REFUND LIABILITY AND LIABILITY RELATED TO SALE OF FUTURE ROYALTIES The Company had the following deferred revenue balances as of June 30, 2024 (in thousands): June 30, 2024 Deferred Revenue: Short-Term Long-Term Total CSL Vifor License Agreement $ 43,296 — $ 43,296 Total $ 43,296 $ — $ 43,296 CSL Vifor License Agreement O n February 18, 2022, the Company entered into a Second Amended and Restated License Agreement, or the Vifor License Agreement, with CSL Vifor, which amended and restated the License Agreement dated May 12, 2017, or the Original License Agreement . The Vifor License Agreement granted CSL Vifor an exclusive license to sell Vafseo to Fresenius Medical Care North America, or FMCNA , and its affiliates, including Fresenius Kidney Care Group LLC, to certain third-party dialysis organizations approved by the Company, to independent dialysis organizations that are members of certain group purchasing organizations and certain non-retail specialty pharmacies, collectively, the Supply Group , in the U.S. The Vifor License Agreement was structured as a profit share arrangement between the Company and CSL Vifor in which the Company would receive approximately 66% of the profits, net of certain pre-specified costs. In addition, CSL Vifor made an upfront payment to the Company of $25.0 million in February 2022 in connection with the amendment and restatement of the Vifor License Agreement, which was recorded as long-term deferred revenue in the accompanying unaudited condensed consolidated balance sheets. On July 10, 2024, the Company and CSL Vifor entered into a Termination and Settlement Agreement, or the Vifor Termination Agreement , pursuant to which the Company and CSL Vifor agreed, among other things, to terminate, effective immediately, the Vifor License Agreement. See Note 16, Subsequent Events , for further information on the Vifor Termination Agreement. Investment Agreements In connection with the Original License Agreement, in May 2017, the Company sold an aggregate of 3,571,429 shares of the Company’s common stock, or 2017 Shares, to CSL Vifor at a price per share of $14.00 for a total of $50.0 million. In February 2022, in connection with the Vifor License Agreement, the Company sold an aggregate of 4,000,000 shares of its common stock, or 2022 Shares , to CSL Vifor at a price per share of $5.00 for a total of $20.0 million. The $18.3 million representing the premium over the closing stock price, or $4.7 million for the 2017 Shares and $13.6 million for the 2022 Shares, represents consideration related to the Vifor License Agreement. The 2017 Shares and 2022 Shares are subject to standstill agreement and are subject to voting agreements. The 2017 Shares and 2022 Shares have not been registered pursuant to the Securities Act of 1933, as amended, or the Securities Act , and were issued and sold in reliance upon the exemption from registration contained in Section 4(a)(2) of the Securities Act and Rule 506 promulgated thereunder as the transaction did not involve any public offering within the meaning of Section 4(a)(2) of the Securities Act. See Note 8, Deferred Revenue, Refund Liability and Liability Related to the Sale of Future Royalties , of the Notes to the Consolidated Financial Statements in the 2023 Form 10-K for a more detailed description of the Vifor License Agreement. Deferred Revenue Recognition The Company evaluated the elements of the Vifor License Agreement in accordance with the provisions of ASC 606 and concluded that the contract counterparty, CSL Vifor, was a customer. The Company identified one performance obligation under the Vifor License Agreement at inception which was the non-sublicensable, non-transferrable license under certain of the Company's intellectual property to (i) sell Vafseo solely to the Supply Group, (ii) sell Vafseo to Designated Wholesalers solely for resale to members of the Supply Group, (iii) conduct medical affairs with respect to Vafseo in the U.S. in the field during the term of the Vifor License Agreement and (iv) use the Akebia trademark solely in connection with the sale of Vafseo. The transaction price of $43.3 million was comprised of the up-front payment of $25.0 million and the premiums paid by CSL Vifor for the 2017 Shares and 2022 Shares of $4.7 million and $13.6 million, respectively. Under the Vifor License Agreement, these payments from CSL Vifor were non-refundable and non-creditable against any other amount due to the Company. In addition, if the Centers for Medicare & Medicaid Services, or CMS, determined that Vafseo was excluded from the Transitional Drug Add-on Payment Adjustment, or TDAPA , the Company had the right to terminate the Vifor License Agreement and would then be required to repay the up-front payment and the premiums paid by CSL Vifor on the 2017 Shares and the 2022 Shares. Given the previous uncertainty associated with a potential future approval of Vafseo by the FDA, and whether Vafseo would be included in certain reimbursement bundles by CMS, the Company constrained the entire transaction price at inception. As a result of the Vifor Termination Agreement, there are no remaining performance obligations under the Vifor License Agreement. Accordingly, the transaction price of $43.3 million was classified as short-term deferred revenue in the accompanying unaudited condensed consolidated balance sheets as of June 30, 2024. Refund Liability to Customer/Working Capital Fund Pursuant to the Vifor License Agreement, CSL Vifor contributed $40.0 million to a working capital fund, or Working Capital Fund , established to partially fund the Company’s costs of purchasing Vafseo from its contract manufacturers. The Company determined the Working Capital Fund did not represent an obligation to transfer goods or services to CSL Vifor in the future and thus under ASC 606 was recorded as a refund liability. The refund liability was considered a debt arrangement with zero coupon interest and the Company imputed interest on the refund liability at a rate of 15.0% per annum, which was determined based on certain factors, including the Company's credit rating, comparable securities yield and the expected repayment period. On March 18, 2022, when the $40.0 million was received from CSL Vifor, the Company recorded an initial discount on the refund liability and a corresponding deferred gain on the condensed consolidated balance sheet. The discount on the refund liability was amortized to interest expense using the effective interest method over the expected term of the Vifor License Agreement. The deferred gain was amortized to interest income on a straight-line basis over the expected term of the Vifor License Agreement. The amortization of the discount was $0.9 million and $1.6 million for the three and six months ended June 30, 2024, respectively, and $0.9 million and $1.7 million for the three and six months ended June 30, 2023, respectively. The amortization of the deferred gain was $0.8 million and $1.7 million for the three and six months ended June 30, 2024, respectively, and $1.0 million and $2.0 million for the three and six months ended June 30, 2023, respectively. On May 3, 2024, the Company and CSL Vifor entered into Amendment #1 to the Vifor License Agreement, or the Amendment . Pursuant to the Amendment, and as modified by the Vifor Termination Agreement, the Company and CSL Vifor agreed to modify the method of repayment of the Working Capital Fund such that the Working Capital Fund will be repaid through quarterly tiered royalty payments ranging from 8% to 14% of the Company's net sales of Vafseo in the U.S., or the WCF Royalty Payments . The WCF Royalty Payments will commence on July 1, 2025, and will continue until the earlier of (i) the cumulative total of the WCF Royalty Payments equals $40.0 million, or (ii) May 31, 2028, or the WCF Royalty Term . The WCF Royalty Payments are subject to minimum true-up milestones of $10.0 million, $20.0 million and $40.0 million, or the WCF Royalty True-Up Payments , on each of May 31, 2026, May 31, 2027 and May 31, 2028, respectively, or the WCF Royalty True-Up Dates . If the cumulative total of the WCF Royalty Payments paid to CSL Vifor on any given WCF Royalty True-Up Date is less than the respective WCF Royalty True-Up Payment, the Company will pay CSL Vifor a one-time payment equal to the difference between the WCF Royalty True-Up Payment and the cumulative total of the WCF Royalty Payments paid by the Company through such WCF Royalty True-Up Date. The Company determined that the terms of the Amendment are not substantially different than the terms of the Vifor License Agreement, and therefore the Amendment was accounted for as a modification. The Company concluded that the 15% discount rate remains appropriate. The Company will reassess the effective rate at each reporting period. As of June 30, 2024, the $40.0 million refund liability is classified as a long-term liability based on management's estimated timing of the repayment of the refund liability to Vifor exceeding one-year. Liability Related to Sale of Future Royalties On February 25, 2021, the Company entered into a royalty interest acquisition agreement, or the Royalty Agreement, with HealthCare Royalty Partners IV, L.P., or HCR , pursuant to which the Company sold to HCR its right to receive royalties and sales milestones for Vafseo in Japan and certain other Asian countries, such countries collectively, the MTPC Territory , and such payments collectively the Royalty Interest Payments , in each case, payable to the Company under the MTPC Agreement. The Royalty Interest Payments are subject to an annual maximum “cap” of $13.0 million, after which the Company will receive 85% of the Royalty Interest Payments for the remainder of that year. The Royalty Interest Payments are also subject to an aggregate maximum “cap” of $150.0 million, after which the Royalty Interest Payments will revert back to the Company. The Company retains the right to receive all potential future regulatory milestones for Vafseo under the MTPC Agreement. At the transaction date, the Company recorded the proceeds received from HCR of $44.8 million (net of certain transaction expenses) as a liability and is amortizing it using the effective interest method over the life of the arrangement. The liability related to sale of future royalties and the debt amortization are based on the Company’s current estimates of future royalties expected to be paid over the life of the arrangement. To the extent the Company’s estimates of future royalty payments are greater or less than previous estimates or the estimated timing of such payments is materially different than previous estimates, the Company will adjust the effective interest rate and recognize related non-cash interest expense on a prospective basis. In the event the Company's estimates of future royalties are less than the proceeds from the sale of future royalties, the Company will not recognize related non-cash interest expense. On a quarterly basis, the Company reassesses the effective interest rate and adjusts the rate prospectively as needed. The annual effective interest rate as of June 30, 2024 was 0% and, therefore the Company did not recognize any non-cash interest expense in the unaudited condensed consolidated statements of operations and comprehensive loss. As a result of its ongoing involvement in the cash flows related to the royalties and sales milestones in the MTPC Territory, the Company will continue to account for these royalties as non-cash royalty revenue which is reflected in license, collaboration and other revenue in the unaudited condensed consolidated statements of operations and comprehensive loss. See Note 8, Deferred Revenue, Refund Liability and Liability Related to Sale of Future Royalties , of the Notes to the Consolidated Financial Statements in the 2023 Form 10-K for a more detailed description of the Royalty Agreement. The Company paid $0.4 million and $0.9 million of royalties to HCR during the three and six months ended June 30, 2024, respectively, and $0.4 million and $1.0 million during the three and six months ended June 30, 2023, respectively. As of June 30, 2024 and December 31, 2023 the balances were as follows (in thousands): Liability related to sale of future royalties June 30, 2024 December 31, 2023 Current portion (included in accrued expenses and other current liabilities) $ 2,013 $ 2,048 Long-term portion 53,101 54,013 Total liability related to sale of future royalties $ 55,114 $ 56,061 |

The term of the Cambridge Lease with respect to the 5,951 square feet of lab space expires on September 11, 2026, with one two-year extension option available. The Cambridge Lease is non-cancelable and is classified as an operating lease. The renewal options with respect to the office, storage and the lab space of the Cambridge Lease were not included in the calculation of the right-of-use asset and operating lease liability as the renewals are not reasonably certain. The Cambridge Lease does not contain residual value guarantees. In arriving at the operating lease liabilities, the Company applied incremental borrowing rates ranging from 6.65% to 6.94%, which were based on the remaining lease term at either the date of adoption of ASC 842 or the effective date of any subsequent lease term extensions. As of June 30, 2024, the remaining lease term for the Cambridge Lease was 2.20 years. Operating lease costs were $1.2 million and $2.5 million for the three and six months ended June 30, 2024, respectively, and $1.4 million and $3.2 million for the three and six months ended June 30, 2023, respectively. Cash paid for amounts included in the measurement of operating lease liabilities was $1.4 million and $2.9 million for the three and six months ended June 30, 2024, respectively, and $1.4 million and $3.1 million for the three and six months ended June 30, 2023, respectively.

As of May 2023, LG Chem assumed all of the rights and obligations of the Company under the Boston Lease and the Company has no further obligations for rent or other payments under the Boston Lease. In accordance with ASC 842, Leases , the Company wrote off the right-of-use asset and lease liability associated with the Boston Lease, and recognized the difference between the right-of-use asset and the lease liability offset by the $1.3 million payment as a loss on lease termination in the unaudited condensed consolidated statements of operations and comprehensive loss of $0.5 million during the three and six months ended June 30, 2023.

The upfront payment of $17.5 million was made during the quarter ended December 31, 2022 and was recognized to cost of product and other revenue. In accordance with ASC 420, Exit or Disposal Cost Obligations , the Company recognized a liability and corresponding expense for the remaining termination fees based on estimated fair value as of December 22, 2022. The Company imputed interest on the liability for the remaining termination fees at a rate of 17.0% per annum, which was determined based on certain factors, including the Company's credit rating, comparable securities yield, and expected repayment period of the remaining termination fees. The Company recorded an initial discount on the remaining termination fees on the consolidated balance sheet on the date of the termination. This resulted in the recording of a liability and corresponding charge to cost of goods sold of $11.2 million during the quarter ended December 31, 2022. The discount on the liability balance is being amortized to interest expense using the effective interest rate method over the term of the liability.

In some instances, the contracts may be cancelled by the third party upon written notice. Litigation and Related Matters The Company is involved from time to time in various legal proceedings arising in the normal course of business. The Company provides disclosure when a loss in excess of any reserve is reasonably possible, and if estimable, the Company discloses the potential loss or range of possible loss. Significant judgment is required to assess the likelihood of various potential outcomes and the quantification of loss in those scenarios. Changes in the Company’s estimates could have a material impact and are recorded as litigation progresses and new information comes to light.

Medice License Agreement On May 24, 2023, or Medice Effective Date , the Company and MEDICE Arzneimittel Pütter GmbH & Co. KG, or Medice , entered into a License Agreement, or the Medice License Agreement , pursuant to which the Company granted to Medice an exclusive license to market and sell Vafseo for the treatment of anemia in adult patients with CKD in the Medice Territory. Under the Medice License Agreement, the Company received an up-front payment of $10.0 million and is eligible to receive the following payments: (i) commercial milestone payments up to an aggregate of $100.0 million, and (ii) tiered royalties ranging from 10% to 30% of Medice's annual net sales of Vafseo in the Medice Territory, subject to reduction in certain circumstances. The royalties will expire on a country-by-country basis upon the latest to occur of (a) the date of expiration of the last-to-expire valid claim of any Company, Medice or joint patent that covers Vafseo in such country in the Medice Territory, (b) the date of expiration of data or regulatory exclusivity for Vafseo in such country in the Medice Territory and (c) the date that is twelve years from first commercial sale of Vafseo in such country in the Medice Territory. Under the Medice License Agreement, the Company retains the right to develop Vafseo for non-dialysis patients with anemia due to CKD in the Medice Territory. If the Company develops Vafseo for non-dialysis patients and Vafseo receives marketing approval in the Medice Territory, Medice will commercialize Vafseo for both indications in the Medice Territory. In this instance, the Company would receive 70% of the net product margin of any sales of Vafseo in the non-dialysis patient population, unless Medice requests to share the cost of the development necessary to gain approval to market Vafseo for non-dialysis patients in the Medice Territory and the parties agree on alternative financial terms. If the Company develops Vafseo for non-dialysis patients, the Company has determined that the activities under the Medice License Agreement represent joint operating activities in which both parties are active participants and of which both parties are exposed to significant risks and rewards that are dependent on the success of the activities. Accordingly, if the Company develops Vafseo for non-dialysis patients, the Company will account for the joint activities in accordance with ASC No. 808, Collaborative Arrangements , or ASC 808 . Additionally, the Company has determined that in the context of the development of Vafseo for non-dialysis patients, Medice does not represent a customer as contemplated by ASC 606-10-15, Revenue from Contracts with Customers – Scope and Scope Exceptions . As a result, the activities conducted pursuant to development activities for Vafseo for non-dialysis patients will be accounted for as a component of the related expense in the period incurred. The Medice License Agreement expires on the date of expiration of all payment obligations due thereunder with respect to Vafseo in the last country in the Medice Territory, unless earlier terminated in accordance with the terms of the Medice License Agreement. Either party may, subject to a cure period, terminate the Medice License Agreement in the event of the other party's uncured material breach. Medice has the right to terminate the Medice License Agreement in its entirety for convenience upon twelve months' prior written notice delivered on or after the date that is twelve months after the Medice Effective Date. The Medice License Agreement provides that the Company and Medice will enter into a supply agreement pursuant to which the Company will supply Vafseo to Medice for commercial use in the Medice Territory. As of June 30, 2024, the Company and Medice have not yet entered into a supply agreement. The Company evaluated the elements of the Medice License Agreement in accordance with the provisions of ASC 606 and concluded Medice is a customer. The Company identified one performance obligation in connection with its obligations under the Medice License Agreement, which is the license, or License Performance Obligation . The transaction price at inception was comprised of the up-front payment of $10.0 million, of which the Company received $8.6 million during the quarter ended June 30, 2023. The remaining $1.4 million was withheld by the German Federal Tax Office and is included in prepaid expenses and other current assets as of June 30, 2024 and other long-term assets as of December 31, 2023 on the unaudited condensed consolidated balance sheets. Pursuant to the terms of the Medice License Agreement, the up-front payment of $10.0 million is non-refundable and non-creditable against any other amount due to the Company and was allocated to the License Performance Obligation, which was satisfied as of the Medice Effective Date. As such, the Company recognized the $10.0 million up-front payment as license, collaboration and other revenue in the unaudited condensed consolidated statements of operations and comprehensive loss during the three and six months ended June 30, 2023. In accordance with ASC 606, the Company will recognize sales-based royalties and milestone payments at the later of when the performance obligation is satisfied or the related sales occur. Medice Letter Agreement On December 6, 2023, the Company and Medice entered into a letter agreement, or the Medice Letter Agreement , pursuant to which the Company agreed to sell to Medice a partial batch of Vafseo in order to achieve packaging validation for the Medice Territory. The Company recognizes revenue under this arrangement when risk of loss passes to Medice and delivery has occurred. As of June 30, 2024, there were immaterial accounts receivable and no contract assets, payables or deferred revenue recorded in connection with the Medice Letter Agreement. MTPC Collaboration Agreement On December 11, 2015, the Company and MTPC entered into a Collaboration Agreement, or the MTPC Agreement , providing MTPC with exclusive development and commercialization rights to Vafseo in the MTPC Territory, which was amended effective as of December 2, 2022. In addition, the Company supplies Vafseo to MTPC for both clinical and commercial use in the MTPC Territory. In February 2021, the Company entered into the Royalty Agreement with HCR, whereby the Company sold its right to receive royalties and sales milestones under the MTPC Agreement, subject to certain caps and other terms and conditions. See Note 8, Deferred Revenue, Refund Liability and Liability Related to Sale of Future Royalties , for additional information and Note 12, License, Collaboration and Other Revenue , of the Notes to the Consolidated Financial Statements in the 2023 Form 10-K for a more detailed description of the MTPC Agreement. The Company evaluated the elements of the MTPC Agreement in accordance with the provisions of ASC 606 and concluded that the contract counterparty, MTPC, is a customer. The Company identified two performance obligations in connection with its material promises under the MTPC Agreement as follows: (i) License, Research and Clinical Supply Performance Obligation and (ii) Rights to Future Know-How Performance Obligation . The transaction price was comprised of: (i) the up-front payment of $20.0 million, (ii) the cost for the Phase 2 studies of $20.5 million, (iii) the cost of all clinical supply provided to MTPC for the Phase 3 studies, (iv) $10.0 million in development milestones received, (v) $25.0 million in regulatory milestones received and (vi) $5.9 million in royalties from net sales of Vafseo. The Company re-evaluates the transaction price in each reporting period and as uncertain events are resolved or other changes in circumstances occur. As of June 30, 2024, all development milestones and $25.0 million in regulatory milestones have been achieved. No other regulatory milestones have been assessed as probable of being achieved and as a result have been fully constrained. The Company allocates the transaction price to each performance obligation based on the Company’s best estimate of the relative standalone selling price. The Company developed a best estimate of the standalone selling price for the Rights to Future Know-How Performance Obligation primarily based on the likelihood that additional intellectual property covered by the license conveyed will be developed during the term of the arrangement and determined it is immaterial. As such, the Company did not develop a best estimate of standalone selling price for the License, Research and Clinical Supply Performance Obligation and allocated the entire transaction price to this performance obligation. Revenue for the License, Research and Clinical Supply Performance Obligation for the MTPC Agreement is being recognized using a proportional performance method, for which all deliverables have been completed. The Company recognizes any revenue from MTPC royalties in the period in which the sales occur. The Company recognized $0.5 million and $0.9 million of revenue from MTPC royalties during each of the three and six months ended June 30, 2024 and 2023, respectively. As noted above, in February 2021, the Company entered into the Royalty Agreement, whereby the Company sold its right to receive these royalties and sales milestones under the MTPC Agreement, subject to certain caps and other terms and conditions. See Note 8, Deferred Revenue, Refund Liability and Liability Related to Sale of Future Royalties , for additional information. The revenue is classified as license and other revenue in the accompanying unaudited condensed consolidated statements of operations and comprehensive loss. As of June 30, 2024, there were no accounts receivable, payables or deferred revenue and $0.5 million in contract assets recorded in connection with the MTPC Agreement. Supply of Drug Product to MTPC On July 15, 2020, the Company and MTPC entered into a supply agreement, or MTPC Supply Agreement , under which the Company supplies Vafseo drug product to MTPC for commercial use in Japan and certain other Asian countries, as contemplated by the MTPC Agreement. See Note 12, License, Collaboration and Other Revenue , of the Notes to the Consolidated Financial Statements in the 2023 Form 10-K for a more detailed description of this supply agreement. On December 16, 2022, the Company, MTPC and Esteve Química, S.A., or Esteve, executed an Assignment of Supply Agreement, or Esteve Assignment Agreement , pursuant to which the Supply Agreement between the Company and Esteve, or Esteve Agreement was assigned to MTPC. The Esteve Assignment Agreement transferred the rights and obligations of the Company under the Esteve Agreement to MTPC. The Company has no further obligation to take delivery of, or pay for, product delivered by Esteve. The Company does not recognize revenue under this arrangement until risk of loss on the drug product passes to MTPC and delivery has occurred and MTPC has accepted the product. The Company recognized $0.7 million in revenue under the MTPC Supply Agreement during the three and six months ended June 30, 2024, and no revenue and $3.7 million in revenue under the MTPC Supply Agreement during the three and six months ended June 30, 2023, respectively. As of June 30, 2024, there were no accounts receivable, deferred revenue or other current liabilities relating to the MTPC Supply Agreement. JT and Torii Sublicense Agreement The Company has an Amended and Restated Sublicense Agreement, which was amended in June 2013, with JT and Torii, or JT and Torii Sublicense Agreement , under which JT and Torii obtained the exclusive sublicense rights for the development and commercialization of ferric citrate hydrate in Japan. JT and Torii are responsible for the future development and commercialization costs in Japan. See Note 12, License, Collaboration and Other Revenue , of the Notes to the Consolidated Financial Statements in the 2023 Form 10-K for a more detailed description of this sublicense agreement. The Company evaluated the elements of the JT and Torii Sublicense Agreement in accordance with the provisions of ASC 606 and concluded that the contract counterparty, JT and Torii, is a customer. The Company identified two performance obligations in connection with its obligations under the JT and Torii Sublicense Agreement: (i) License and Supply Performance Obligation and (ii) Rights to Future Know-How Performance Obligation . The Company developed a best estimate of the standalone selling price for the Rights to Future Know-How Performance Obligation primarily based on the likelihood that additional intellectual property covered by the license conveyed will be developed during the term of the arrangement and determined it immaterial. As such, the Company allocated the entire transaction price to the License and Supply Performance Obligation. The Company recognized license revenue of $1.3 million and $2.5 million during the three and six months ended June 30, 2024, respectively, and $1.4 million and $2.5 million during the three and six months ended June 30, 2023, respectively, related to royalties earned on net sales of ferric citrate hydrate in Japan under the trade name Riona. The Company records the associated mid-single digit percentage of net sales royalty expense due to Panion, the licensor of Riona, in the same period as the royalty revenue from JT and Torii is recorded. |

(3) This table includes inducement awards that are subject to the terms and conditions of the applicable plan but were granted as inducement awards consistent with Nasdaq Listing Rule 5635(c)(4) and not under the applicable plan: 1,496,428 options included as outstanding under the 2014 Plan in the table and 2,374,950 options included as outstanding under the 2023 Plan in the table as of June 30, 2024 and 1,616,019 options included as outstanding under the 2014 Plan and 794,000 options included as outstanding under the 2023 Plan in the table as of December 31, 2023. Common Stock Options and Stock Appreciation Rights During the six months ended June 30, 2024, the Company issued 3,432,500 options to employees under the 2023 Plan. Options and SARs granted by the Company generally vest over periods of between 12 and 48 months, subject, in each case, to the individual’s continued service through the applicable vesting date. Options and SARs generally vest either 100% on the first anniversary of the grant date or in installments of (i) 25% at the one year anniversary and (ii) 12 equal quarterly installments beginning after the one year anniversary of the grant date, subject to the individual’s continuous service with the Company. Options and SARs generally expire ten years after the date of grant. The Company also maintains an inducement award program with a share pool that is separate from the Company's equity plans under which inducement awards may be granted consistent with Nasdaq Listing Rule 5635(c)(4). During the six months ended June 30, 2024, the Company granted 1,604,950 options to purchase shares of the Company’s common stock to new hires as inducements to such employees entering into employment with the Company, of which 1,604,950 options remained outstanding as of June 30, 2024. The Company grants annual service-based stock options to employees and directors and SARs to certain executives under the 2023 and 2014 Plans. In addition, the Company issues stock options to directors, new hires and occasionally to other employees not in connection with the annual grant process. Finally, the Company grants performance-based stock options which generally vest in connection with the achievement of specified commercial, regulatory and corporate milestones. The performance-based stock options also generally feature a time-based vesting component. The expense recognized for these awards is based on the grant date fair value of the Company’s common stock multiplied by the number of options granted and recognized over time based on the probability of meeting such commercial, regulatory and corporate milestones. The combined stock option activity for the six months ended June 30, 2024, is as follows: Stock Weighted Average Exercise Price Weighted-Average Contractual Life (years) Aggregate Intrinsic Value (in thousands) Outstanding at December 31, 2023 13,312,835 $ 4.20 7.27 years — Granted 5,037,450 $ 1.57 — — Exercised (304,152) $ 0.51 — — Expired (119,043) $ 21.02 Canceled and forfeited (648,270) $ 3.11 — — Outstanding at June 30, 2024 17,278,820 $ 3.42 7.37 years $ 1,521 Exercisable at June 30, 2024 8,559,257 $ 5.40 5.59 years As of June 30, 2024, there was approximately $9.3 million of unrecognized compensation costs related to stock options, which is expected to be recognized over a weighted average period of 2.94 years. Restricted Stock Units Generally, restricted stock units, or RSUs , granted by the Company vest in one of the following ways: (i) 100% of each RSU grant vests on the first anniversary of the grant date, (ii) one third of each RSU grant vests on the first, second and third anniversaries of the grant date, or (iii) one third of each RSU grant vests on the first anniversary of the grant date and the remaining two thirds vests in eight substantially equal quarterly installments beginning after the one year anniversary, subject, in each case, to the individual’s continued service through the applicable vesting date. The grant-date fair value of the RSUs is recognized as expense on a straight-line basis. The Company determines the fair value of the RSUs based on the closing price of the common stock on the date of the grants. The Company also periodically grants performance-based restricted stock units, or PSUs , to employees under the 2023 Plan and previously granted PSUs under the 2014 Plan. The PSUs granted by the Company generally vest in connection with the achievement of specified commercial, regulatory and corporate milestones. The PSUs also generally feature a time-based vesting component. The expense recognized for these awards is based on the grant date fair value of the Company’s common stock multiplied by the number of units granted and recognized over time based on the probability of meeting such commercial, regulatory and corporate milestones. RSU and PSU activity is as follows: 2014 Plan 2023 Plan Number of Shares Weighted Average Fair Value Number of Shares Weighted Average Fair Value Outstanding as of December 31, 2023 3,339,869 $ 1.30 603,400 $ 1.48 Granted — $ — 3,968,200 $ 1.59 Vested (1,478,822) $ 1.62 (210,000) $ 1.20 Forfeited and canceled (210,678) $ 0.90 (48,200) $ 1.68 Outstanding as of June 30, 2024 1,650,369 $ 1.07 4,313,400 $ 1.59 As of June 30, 2024, there was $7.3 million of unrecognized compensation costs related to time-based RSUs and PSUs, which is expected to be recognized over a weighted-average period of 2.25 years. Employee Stock Purchase Plan On June 6, 2019, the Company's stockholders approved the Amended and Restated 2014 Employee Stock Purchase Plan, or ESPP . Under the ESPP substantially all employees may voluntarily enroll to purchase shares of the Company’s common stock through payroll deductions at a price equal to 85% of the lower of the fair market values of the stock as of the beginning or the end of the six-month offering period. An employee's payroll deductions under the ESPP are limited to 15% of the employee's compensation, and an employee may not purchase more than $25,000 worth of stock during any calendar year. In addition, an employee may not purchase more than 1,500 shares in any offering period. As of June 30, 2024 and December 31, 2023, a total of 4,545,480 and 4,637,801 shares of the Company’s common stock were available for future issuance under the ESPP, respectively. The Company issued 92,321 shares under the ESPP during the six months ended June 30, 2024. Stock-Based Compensation Expense The Black-Scholes option pricing model is used to estimate the fair value of the stock options. The weighted-average assumptions used in calculating the fair values of the rights to acquire stock under the 2023 Plan, the 2014 Plan and inducement awards were as follows: Three Months Ended June 30, Six Months Ended June 30, Stock Options 2024 2023 2024 2023 Risk-free interest rate 4.24 % - 4.66% 3.67 % - 3.99% 3.90% - 4.66% 3.54% - 3.99% Expected volatility 109.98 % - 118.61% 102.31 % - 111.71% 109.98% - 118.61% 100.97% - 111.71% Expected term (years) 5.51 years - 6.25 years 5.51 years - 6.25 years 5.51 years - 6.25 years 5.51 years - 6.25 years Expected dividend yield —% —% —% —% Weighted average grant date fair value $0.91 $0.97 $1.35 $0.56 The Company has classified stock-based compensation in its unaudited condensed consolidated statements of operations and comprehensive loss as follows (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 Cost of goods sold $ 83 $ 73 $ 169 $ 139 Research and development 396 532 815 1,202 Selling, general and administrative 1,593 2,685 3,410 4,220 Restructuring — 200 38 418 Total stock-based compensation $ 2,072 $ 3,490 $ 4,432 $ 5,979 |

NET LOSS PER SHARE | NET LOSS PER SHARE Potentially dilutive securities, warrants, common stock options, RSUs and SARs have been excluded from the calculation of diluted net loss per share as their effects would be anti-dilutive. For periods in which the Company reports a net loss, the weighted average number of shares outstanding used to calculate both basic and diluted net loss per share were the same. The shares in the table below were excluded from the calculation of diluted net loss per share, prior to the use of the treasury stock method, due to their anti-dilutive effect: Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 Warrants (1) 3,076,923 — 3,076,923 — Outstanding common stock options 16,643,507 13,118,185 16,643,507 13,118,185 Unvested RSUs 5,963,769 4,596,551 5,963,769 4,596,551 Stock appreciation rights 635,313 635,313 635,313 635,313 Total 26,319,512 18,350,049 26,319,512 18,350,049 |

Subsequent Events [Abstract] | |
SUBSEQUENT EVENTS | SUBSEQUENT EVENTS The Company has evaluated events and transactions occurring after the balance sheet date through the filing date of this Quarterly Report on Form 10-Q with the SEC, to ensure that the unaudited condensed consolidated financial statements include appropriate disclose of events both recognized in the accompanying unaudited condensed consolidated financial statements as of June 30, 2024, and events which occurred subsequently but were not recognized in the consolidated financial statements. The Company has concluded that no subsequent events have occurred that require disclosure other than the following: CSL Vifor Termination and Settlement Agreement On July 10, 2024, the Company and CSL Vifor entered into the Vifor Termination Agreement, pursuant to which, the Company and CSL Vifor agreed, among other things, to terminate, effective immediately, the Vifor License Agreement, pursuant to which the Company granted to CSL Vifor an exclusive license to sell Vafseo to the Supply Group in the U.S. Under the Vifor License Agreement, CSL Vifor contributed $40.0 million to the Working Capital Fund, established to partially fund the Company’s costs of purchasing Vafseo from its contract manufacturers. Pursuant to the terms of the Vifor Termination Agreement, and generally consistent with the terms of the Vifor License Agreement, as amended, the Company has agreed to repay the Working Capital Fund to CSL Vifor through the WCF Royalty Payments. The WCF Royalty Payments will commence on July 1, 2025, and will continue until the earlier of (i) the cumulative total of the WCF Royalty Payments equals $40.0 million, or (ii) May 31, 2028. See Note 8, Deferred Revenue, Refund Liability and Liability Related to Sale of Future Royalties , for further information on the repayment of the Working Capital Fund. In addition, the Company will pay CSL Vifor decreasing quarterly tiered royalty payments ranging from a high single-digit percentage of the Company’s net sales of Vafseo up to $450.0 million to mid-single digit percentage of the Company’s net sales of Vafseo above $450.0 million, in each case, in the U.S. during a calendar year, or the Settlement Royalty Payments . The Settlement Royalty Payments will commence upon the first sale of Vafseo by the Company, its affiliates or third-party licensees to a third party for use in the U.S., and will continue until the later of the (i) expiration of the last-to-expire valid claim listed in the FDA Orange Book that would be infringed by the making, using, selling or importing of Vafseo in the U.S. or (ii) the expiration of marketing or regulatory exclusivity for Vafseo in the U.S., or the Settlement Royalty Term . Beginning on July 1, 2027 and throughout the Settlement Royalty Term, the Company has the option to make a one-time payment to CSL Vifor, or the Royalty Buy-Down Option , upon which the Settlement Royalty Payments will be adjusted as of the date of exercise of the Royalty Buy-Down Option such that the Company will then only pay CSL Vifor quarterly royalty payments based on a mid-single digit percentage of the Company’s net sales of Vafseo up to $450.0 million in the U.S. during a calendar year in lieu of the above Settlement Royalty Payments. If the Company exercises the Royalty Buy-Down Option, the WCF Royalty Payments will continue as described above. The WCF Royalty Payments, the Settlement Royalty Payments and the Royalty Buy-Down Option are in consideration for the termination of the Vifor License Agreement and all obligations thereunder, and the covenants and agreements set forth in the Vifor Termination Agreement, including the settlement and release of all disputes and claims arising from the Vifor License Agreement. Amendment to BlackRock Credit Agreement On July 10, 2024, in connection with the Vifor Termination Agreement, the Company and Kreos entered into the BlackRock Credit Amendment. The BlackRock Credit Amendment includes certain covenants of the Company related to the Vifor Termination Agreement. See Note 7, Indebtedness |

SUMMARY OF SIGNIFICANT ACCOUN_2
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies) | 6 Months Ended |
Jun. 30, 2024 | |
Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the U.S., or GAAP . Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification, or ASC , and Accounting Standards Update, or ASU, of the Financial Accounting Standards Board, or FASB . |
Principles of Consolidation | The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in the consolidated financial statements herein. |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenue and expenses, classification of the expenses, assets and liabilities and the disclosure of contingent assets and liabilities as of and during the reported period. On an ongoing basis, management evaluates its estimates. Management bases its estimates and assumptions on historical experience when available and on various factors, including expected business and operational changes, sensitivity and volatility associated with the assumption that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of the assets and liabilities that are not readily apparent from other sources. In certain circumstances, management must apply significant judgment in this process. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes, and management selects an amount that falls within that range of reasonable estimates. Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period they become known. Significant estimates and judgments reflected in these unaudited condensed consolidated financial statements include, but are not limited to: accrued expenses, other long-term liabilities, product revenues, including various rebates, returns and reserves related to product sales, inventories, classification of expenses between cost of goods sold, R&D and selling, general and administrative, long-term assets, including the Company's right-of-use assets, intangible asset and goodwill. |
Cash, Cash Equivalents and Restricted Cash | Cash, Cash Equivalents and Restricted Cash In determining its cash, cash equivalents and restricted cash, the Company considers only those highly liquid investments, readily convertible to cash within 90 days from the date of purchase to be cash equivalents. As of June 30, 2024, cash and cash equivalents primarily included cash on hand. Restricted cash represents amounts required to secure the outstanding letter of credit in connection with the Company’s office and laboratory space in Cambridge, Massachusetts, or the Cambridge Lease . Restricted cash is included in “other long-term assets” in the consolidated balance sheets. |
Concentration of Credit Risk | Concentration of Credit Risk Cash, cash equivalents and accounts receivable are the only financial instruments that potentially subject the Company to concentrations of credit risk. The Company maintains cash accounts principally at two financial institutions in the U.S., which at times, may exceed the Federal Deposit Insurance Corporation's limits. The Company has not experienced any losses from cash balances in excess of the insurance limit. The Company's management does not believe the Company is exposed to significant credit risk at this time due to the financial condition of the financial institutions where its cash is held. The Company makes judgments as to its ability to collect outstanding receivables and provides an allowance for receivables when collection becomes doubtful. Provisions are made based upon a specific review of all significant outstanding receivables and the overall quality and age of those invoices not specifically reviewed as well as historical payment patterns and existing economic factors. The Company believes that credit risks associated with its customers and collaboration partners are not significant. The Company's allowance for credit losses was $0.2 million and $1.0 million as of June 30, 2024 and December 31, 2023, respectively. For the six months ended June 30, 2024, net recoveries were $0.2 million, inclusive of an incremental allowance for credit losses of $0.2 million for the three months ended June 30, 2024. Write-offs were $0.6 million for the three and six months ended June 30, 2023. Manufacturing and Distribution Risk The Company is dependent on third-party manufacturers, logistics companies and distributors to supply products for commercial activities associated with its product and product candidates, as applicable. In particular, the Company relies and expects to continue to rely on a small number of manufacturers to supply it with its requirements for the active pharmaceutical ingredients and formulated drugs related to the Company's product and product candidate activities. These activities, including the commercialization of Auryxia and Vafseo, could be adversely affected by a significant interruption in the supply of active pharmaceutical ingredients and formulated drugs or distribution of finished product to the market. |
Recent Accounting Pronouncements Not Yet Adopted | Recent Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures . ASU 2023-07 requires disclosure of significant segment expenses that are regularly provided to the chief operating decision maker, or CODM, and included within the segment measure of profit or loss, an amount and description of its composition for other segment items to reconcile to segment profit or loss, and the title and position of the entity’s CODM. ASU 2023-07 will be applied retrospectively and is effective for annual reporting periods in fiscal years beginning after December 15, 2023, and interim reporting periods in fiscal years beginning after December 31, 2024. The Company is currently reviewing the impact that the adoption of ASU 2023-07 may have on its consolidated financial statements and disclosure. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures . ASU 2023-09 requires public companies to annually (i) disclose specific categories in the rate reconciliation and (ii) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). ASU 2023-09 will be effective for the annual reporting periods in fiscal years beginning after December 15, 2024. The Company is currently evaluating ASU 2023-09 and does not expect it to have a material effect on the Company’s consolidated financial statements. |
