Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Overview and Nature of the Business | 1. Flexion Therapeutics, Inc. (“Flexion” or the “Company”) was incorporated under the laws of the state of Delaware on November 5, 2007. Flexion is a biopharmaceutical company focused on the discovery, development and commercialization of novel, local therapies for the treatment of patients with musculoskeletal conditions, beginning with osteoarthritis, or OA, a type of degenerative arthritis. The Company has an approved product, ZILRETTA ® The accompanying condensed consolidated financial statements have been prepared on a basis which assumes that the Company will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the normal course of business. The Company has incurred recurring losses and negative cash flows from operations. As of June 30, 2020, the Company had cash, cash equivalents, and marketable securities of approximately $200.6 million. The Company is subject to risks and uncertainties common to companies in the biopharmaceutical industry, including, but not limited to, new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations, and the ability to secure additional capital to fund operations. Successfully commercializing ZILRETTA requires significant sales and marketing efforts and the Company’s pipeline programs will require significant additional research and development efforts, including extensive preclinical and clinical testing. These activities will in turn require significant amounts of capital, qualified personnel and adequate infrastructure. There can be no assurance when, if ever, the Company will realize significant revenue from the sales of ZILRETTA or if the development efforts supporting the Company’s pipeline, including future clinical trials, will be successful. The Company’s operations have been and continue to be affected by the ongoing global pandemic of a novel strain of coronavirus (“COVID-19”) and the resulting volatility and uncertainty it has caused. In March 2020, the World Health Organization declared COVID-19 a pandemic and recommended containment and mitigation measures worldwide. The COVID-19 pandemic has caused significant volatility and uncertainty, which could result in a prolonged economic downturn that has disrupted and is expected to continue to disrupt the Company’s business. While there have been no material asset impairments recorded to date, any prolonged material future disruptions to the work of the Company’s employees, suppliers, contract manufacturers, or vendors, or to the operations of physicians that administer ZILRETTA could negatively impact the Company’s operations, availability of supplies, carrying value of assets, or the Company’s operating results or cash flows. In the Company’s Quarterly Report on Form 10-Q for the three months ended March 31, 2020, the Company disclosed that there was substantial doubt about its ability to continue as a going concern as a result of conditions that existed as of March 31, 2020. Specifically, those conditions included an expected material decline in revenue due to COVID-19 as compared to its prior expectations, and as a result, it was deemed probable that the Company would fail to meet the revenue covenant within the Company’s amended and restated credit and security agreement described in Note 9. In the three months following March 31, 2020, the Company took certain actions designed to alleviate the substantial doubt, including reducing certain operating expenses through hiring and travel freezes, suspension and/or termination of active clinical trials, reduction of certain marketing expenses, and elimination of non-essential operating expenses, modifying the amended and restated credit and security agreement, and completing an equity offering of 10,615,385 shares of the Company’s common stock which resulted in $96.8 million of net proceeds to the Company. The amendment to the amended and restated credit and security agreement resulted in a change in the minimum liquidity threshold that determines whether or not the revenue covenant is applicable. Pursuant to the amendment, the Company’s minimum liquidity threshold now includes certain accounts receivable as deemed eligible under the amended and restated credit and security agreement, in addition to cash, cash equivalents, and marketable securities. Additionally, prior to May 2021, the minimum revenue covenant, if it applies in the future, is unmodified and is based on the greater of (i) a conservative percentage of the year’s approved forecast and (ii) modest growth over the trailing twelve months of actual revenues. Beginning in May 2021, the minimum revenue covenant, if it applies, will be the greatest of (i) a conservative percentage of the year’s approved forecast, (ii) modest growth over the trailing twelve months of actual revenues and (iii) 100% of the minimum revenue covenant amount for the preceding month. As of June 30, 2020, the Company was in compliance with all covenants under the amended and restated credit and security agreement. Additionally, while purchases of ZILRETTA by physicians, clinics, and certain medical centers or hospitals (i.e., healthcare providers who administer ZILRETTA to patients) dropped precipitously in the latter part of March into early April due to the adverse impact of COVID-19 on the operations of these healthcare providers, as the second quarter progressed, there was an increase in demand for ZILRETTA such that total ZILRETTA purchases by healthcare providers for the second quarter were consistent with the first quarter of this year . T he Company currently expects to be able to maintain the $ 80.0 million liquidity threshold for at least 12 months following the issuance of these financial statements . Taking these factors together, the revenue covenant under the amended and restated credit and security agreement is not expected to be applicable through 12 months from the issuance of the financial statements . Management believes that current cash, cash equivalents, and marketable securities on hand at June 30, 2020 will be sufficient to fund operations for at least the next 12 months from the issuance date of these financial statements . The future viability of the Company is dependent on its ability to fund its operations through sales of ZILRETTA, and/or raise additional capital, such as through debt or equity offerings, as needed. If the Company is unable to grow sales of ZILRETTA in future periods, it is possible that the Company may not maintain compliance with the revenue covenant in the period after 12 months from issuance of these financial statements and would need to seek additional financing. The Company may not be able to obtain financing on acceptable terms, or at all. In particular, as a result of the COVID-19 pandemic and actions taken to slow its spread, the global credit and financial markets have experienced extreme volatility and disruptions, including diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about economic stability. If the equity and credit markets deteriorate, it may make any additional debt or equity financing more difficult, more costly and more dilutive. If the Company is unable to obtain funding on a timely basis, the Company may need to curtail its operations, including the commercialization of ZILRETTA and research and development activities, which could adversely affect its prospects. |

Summary of Significant Accounting Policies | 2. Basis of Presentation The accompanying condensed consolidated financial statements as of June 30, 2020, and for the three and six months ended June 30, 2020 and 2019, have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) and Generally Accepted Accounting Principles (“GAAP”) for consolidated financial information including the accounts of the Company and its wholly-owned subsidiary after elimination of all significant intercompany accounts and transactions. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, these condensed consolidated financial statements reflect all adjustments which are necessary for a fair statement of the Company’s financial position and results of its operations, as of and for the periods presented. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K filed with the SEC on March 12, 2020. The information presented in the condensed consolidated financial statements and related notes as of June 30, 2020 and December 31, 2019, and for the three and six months ended June 30, 2020 and 2019, is unaudited. The December 31, 2019 condensed consolidated balance sheet included herein was derived from the audited financial statements as of that date, but does not include all disclosures, including notes, required by GAAP for complete financial statements. Interim results for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2020, or any future period. Recent Accounting Pronouncements Accounting Standards Recently Adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments In July 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement of the standard as the quarter ended September 30, 2018. The Company adopted the remainder of the standard as of January 1, 2020. The adoption of the remainder of ASU 2018-13 did not have a material impact on the Company’s condensed consolidated financial statements. Consolidation The accompanying condensed consolidated financial statements include the Company and its wholly-owned subsidiary, Flexion Therapeutics Securities Corporation. The Company has eliminated all intercompany transactions for the three and six months ended June 30, 2020 and the year ended December 31, 2019. Revenue Recognition On October 6, 2017, the U.S. Food and Drug Administration, (FDA), approved ZILRETTA. The Company entered into a limited number of arrangements with specialty distributors and a specialty pharmacy in the U.S. to distribute ZILRETTA. The Company recognizes revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606 - Revenue from Contracts with Customers (“Topic 606”). Under Topic 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to be entitled to in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of Topic 606, the entity performs the following five steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to arrangements that meet the definition of a contract with a customer under Topic 606, including when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of Topic 606, the Company assesses the goods or services promised within each contract, determines those that are performance obligations, and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Product Revenue, Net — The Company primarily sells ZILRETTA to specialty distributors and a specialty pharmacy, who then subsequently resell ZILRETTA to physicians, clinics and certain medical centers or hospitals. The Company also contracts directly with healthcare providers and intermediaries such as Group Purchasing Organizations (“GPOs”). In addition, the Company enters into arrangements with government payers that provide for government mandated rebates and chargebacks with respect to the purchase of ZILRETTA. The Company recognizes revenue on product sales when the customer obtains control of the Company's product, which occurs at a point in time (upon delivery to the customer). The Company has determined that the delivery of ZILRETTA to its customers constitutes a single performance obligation. There are no other promises to deliver goods or services beyond what is specified in each accepted customer order. The Company has assessed the existence of a significant financing component in the agreements with its customers. The trade payment terms with customers do not exceed one year and therefore the Company has elected to apply the practical expedient and no amount of consideration has been allocated as a financing component. Product revenues are recorded net of applicable reserves for variable consideration, including discounts and allowances. Transaction Price, including Variable Consideration — Revenues from product sales are recorded at the net sales price (transaction price), which includes estimates of variable consideration for which reserves are established. Components of variable consideration include trade discounts and allowances, product returns, government chargebacks, discounts and rebates, and other incentives, such as voluntary patient assistance, and other fee for service amounts that are detailed within contracts between the Company and its customers relating to the Company’s sale of its products. These reserves, as detailed below, are based on the amounts earned, or to be claimed on the related sales, and are classified as reductions of accounts receivable (if the amount is payable to the customer) or a current liability (if the amount is payable to a party other than a customer). These estimates take into consideration a range of possible outcomes which are probability-weighted in accordance with the expected value method in Topic 606 for relevant factors such as current contractual and statutory requirements, specific known market events and trends, industry data, and forecasted customer buying and payment patterns. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the respective underlying contracts. The amount of variable consideration which is included in the transaction price may be constrained and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized under the contract will not occur in a future period. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results in the future vary from the Company’s original estimates, the Company will adjust these estimates, which would affect net product revenue and earnings in the period such variances become known. Service Fees and Allowances — The Company compensates its customers and GPOs for sales order management, data, and distribution services. However, the Company has determined such services received to date are not distinct from the Company’s sale of products to the customer and, therefore, these payments have been recorded as a reduction of revenue within the statement of operations and comprehensive loss through June 30, 2020, as well as a reduction to trade receivables, net on the condensed consolidated balance sheets. Product Returns — Consistent with industry practice, the Company generally offers customers a limited right of return for product that has been purchased from the Company based on the product’s expiration date. The Company estimates the amount of its product sales that may be returned by its customers and records this estimate as a reduction of revenue in the period the related product revenue is recognized, as well as within accrued expenses and other current liabilities, net, on the condensed consolidated balance sheets. The Company currently estimates product return liabilities using available industry data and its own sales information, including its visibility into the inventory remaining in the distribution channel. The Company has received an immaterial amount of returns to date and believes that future returns of ZILRETTA will be minimal. Chargebacks — Chargebacks for fees and discounts to qualified government healthcare providers represent the estimated obligations resulting from contractual commitments to sell products to qualified VA hospitals and 340b entities at prices lower than the list prices charged to customers who directly purchase the product from the Company. The 340b Drug Discount Program is a U.S. federal government program created in 1992 that requires drug manufacturers to provide outpatient drugs to eligible health care organizations and covered entities at significantly reduced prices. Customers charge the Company for the difference between what they pay for the product and the statutory selling price to the qualified government entity. These reserves are established in the same period that the related revenue is recognized, resulting in a reduction of product revenue and trade receivables, net. Chargeback amounts are generally determined at the time of resale to the qualified government healthcare provider by customers, and the Company generally issues credits for such amounts within a few weeks of the customer’s notification to the Company of the resale. Reserves for chargebacks consist of credits that the Company expects to issue for units that remain in the distribution channel inventories at each reporting period-end that the Company expects will be sold to qualified healthcare providers, and chargebacks that customers have claimed, but for which the Company has not yet issued a credit. Government Rebates — The Company is subject to discount obligations under state Medicaid programs and Medicare. These reserves are recorded in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability which is included in accrued expenses and other current liabilities on the condensed consolidated balance sheets. For Medicare, the Company also estimates the number of patients in the prescription drug coverage gap for whom the Company will owe an additional liability under the Medicare Part D program. The Company estimates its exposure to utilization from the Medicare Part D coverage gap discount program to be immaterial. For Medicaid programs, the Company estimates the portion of sales attributed to Medicaid patients and records a liability for the rebates to be paid to the respective state Medicaid programs. The Company’s liability for these rebates consists of invoices received for claims from prior quarters that have not been paid or for which an invoice has not yet been received, estimates of claims for the current quarter, and estimated future claims that will be made for product that has been recognized as revenue, but which remains in the distribution channel inventories at the end of each reporting period. Purchaser/Provider Discounts and Rebates — Beginning in the third quarter of 2019, the Company began offering rebates to eligible purchasers and healthcare providers that are variable based on volume of product purchased. Rebates are based on actual purchase levels during the rebate purchase period. The Company estimates these rebates and records such estimates in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability. Other Incentives — Other incentives which the Company offers include voluntary patient assistance programs, such as the co-pay assistance program, which are intended to provide financial assistance to qualified commercially-insured patients with prescription drug co-payments required by payers. The calculation of the accrual for co-pay assistance is based on an estimate of claims and the cost per claim that the Company expects to receive associated with product that has been recognized as revenue, but remains in the distribution channel inventories at the end of each reporting period. The adjustments are recorded in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability which is included as a component of accrued expenses and other current liabilities on the condensed consolidated balance sheets. To date, the Company’s only source of product revenue has been from the U.S. sales of ZILRETTA, which it began shipping to customers in October 2017. The following table summarizes activity in each of the product revenue allowance and reserve categories for the three and six months ended June 30, 2020 and 2019: (In thousands) Service Fees, Allowances and Chargebacks Government Rebates and Other Incentives Product Returns Purchaser/Provider Discounts and Rebates Total Balance as of December 31, 2019 $ 1,847 $ 248 $ 402 $ 1,656 $ 4,153 Provision related to sales in the current quarter 1,590 254 114 526 2,484 Credits and payments made (1,852 ) (199 ) (10 ) (1,656 ) (3,717 ) Adjustments related to prior period sales — 95 — — 95 Balance as of March 31, 2020 1,585 398 506 526 3,015 Provision related to sales in the current quarter 1,417 133 98 892 2,540 Credits and payments made (1,172 ) (262 ) (1 ) (528 ) (1,963 ) Adjustments related to prior period sales — 90 — 2 92 Balance as of June 30, 2020 $ 1,830 $ 359 $ 603 $ 892 $ 3,684 Balance as of December 31, 2018 $ 601 $ 491 $ 125 $ — $ 1,217 Provision related to sales in the current quarter 741 24 57 — 822 Credits and payments made (332 ) (36 ) (33 ) — (401 ) Balance as of March 31, 2019 1,010 479 149 — 1,638 Provision related to sales in the current quarter 1,196 121 92 — 1,409 Credits and payments made (1,157 ) (65 ) (6 ) — (1,228 ) Balance as of June 30, 2019 $ 1,049 $ 535 $ 235 $ — $ 1,819 License Agreement – On March 30, 2020, the Company entered into an exclusive license agreement with Hong Kong Tainuo Pharma Ltd. (“HK Tainuo”) and Jiangsu Tainuo Pharmaceutical Co. Ltd. (“Jiangsu Tainuo”), a subsidiary of China Shijiazhuang Pharmaceutical Co, Ltd. for the development and commercialization of ZILRETTA in Greater China (consisting of mainland China, Hong Kong and Macau, and Taiwan). Under the terms of the agreement, HK Tainuo is obligated to pay the Company an upfront payment of $10.0 million. The Company is also eligible to receive up to $32.5 million in aggregate development, regulatory and commercial sales milestone payments. All payments received from HK Tainuo are subject to the applicable Hong Kong withholding taxes. HK Tainuo will be responsible for the clinical development, product registration and commercialization of ZILRETTA in Greater China and Jiangsu Tainuo will serve as the guarantor of HK Tainuo’s obligations and responsibilities under the agreement. The Company is solely responsible for the manufacture and supply of ZILRETTA to HK Tainuo for all clinical and commercial activities. The terms related to product manufacturing and supply, including pricing and minimum purchase requirements agreed to in the license agreement, will be covered by a separate supply agreement. All amounts owed to the Company are nonrefundable and non-creditable once paid. Unless terminated earlier in accordance with its terms, the license agreement continues in effect in perpetuity or as long as HK Tainuo or Jiangsu Tainuo continue to sell ZILRETTA in Greater China. Either party may terminate the agreement prior to expiration in the event of a material breach if not cured within 60 days from the date of notice of such breach (30 days in the case of payment obligations), or either party files for bankruptcy. The Company also has the right to terminate the agreement if HK Tainuo, Jiangsu Tainuo or any affiliate of each, commences any action or proceeding that challenges the validity, enforceability or scope of any Company patent in Greater China. Upon any such termination, the license granted to HK Tainuo will terminate and all know-how and patents will revert back to the Company. The revenue related to the upfront payment of $10.0 million, of which $5.0 million was received as of June 30, 2020 and the remaining $5.0 million is due in the third quarter of 2020, will be recognized as the Company’s supply obligation is fulfilled over the term of the supply agreement, which has not yet commenced. The Company concluded that the license and supply performance obligations were not distinct, and therefore the transaction price will be recognized as revenue over the period that the Company performs its supply obligations. revenue was recognized associated with this contract as of June 30, 2020 . Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that may affect the reported amounts of assets and liabilities, revenue and expenses and related disclosures. The Company bases estimates and judgments on historical experience and on various other factors that it believes to be reasonable under the circumstances. The most significant estimates in these condensed consolidated financial statements include estimates related to revenue recognition and accrued expenses related to preclinical and clinical development costs. The Company’s actual results may differ from these estimates under different assumptions or conditions. The Company evaluates its estimates on an ongoing basis. Changes in estimates are reflected in reported results in the period in which they become known by the Company’s management. The full extent to which the COVID-19 pandemic will directly or indirectly impact the Company’s business, results of operations and financial condition, including sales, expenses, reserves and allowances, clinical trials, research and development costs and employee-related amounts, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain or treat it, as well as the economic impact on local, regional, national and international customers and markets. The Company has made estimates of the impact of COVID-19 within its financial statements and there may be changes to those estimates in future periods. Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Depreciation and amortization expense is recognized using the straight-line method over the following estimated useful lives: Estimated Useful Life (Years) Computers, office equipment, and minor computer software 3 Computer software 7 Manufacturing equipment 7-10 Furniture and fixtures 5 Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life of the related asset. Costs of major additions and improvements are capitalized and depreciated on a straight-line basis over their useful lives. Repairs and maintenance costs are expensed as incurred. Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is credited or charged to income. Property and equipment includes construction-in-progress that is not yet in service. Foreign Currencies The Company maintains a bank account denominated in British Pounds. All foreign currency payables and cash balances are measured at the applicable exchange rate at the end of the reporting period. All associated gains and losses from foreign currency transactions are reflected in the consolidated statements of operations. Leases The Company determines if an arrangement is a lease at contract inception. Operating lease assets represent a right to use an underlying asset for the lease term and operating lease liabilities represent an obligation to make lease payments arising from the lease. Operating lease liabilities with a term greater than one year and their corresponding right-of-use assets are recognized on the balance sheet at the commencement date of the lease based on the present value of lease payments over the expected lease term. Certain adjustments to the right-of-use asset may be required for items such as initial direct costs paid or incentives received. The Company made an accounting policy election to expense leases with a term of one year or less on a straight-line basis over the lease term. To date, the Company has not identified any material short-term leases, either individually or in the aggregate. As the Company’s leases do not provide an implicit rate, the Company utilized the appropriate incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. The Company estimated the incremental borrowing rate based on a yield curve analysis of companies with a similar credit rating to its own, which was calculated using a number of financial ratios and qualitative considerations of the Company’s business. The yields on the Company’s currently outstanding debt (the 2024 Convertible Notes and term loan) were also used as inputs to the analysis to calculate a spread, adjusted for factors that reflect the profile of secured borrowing over the expected term of the lease. The components of a lease should be split into three categories: lease components (e.g., land, building, etc.), non-lease components (e.g., common area maintenance, utilities, performance of manufacturing services, purchase of inventory, etc.), and non-components (e.g., property taxes, insurance, etc.). Then the fixed contract consideration (including any related to non-components) must be allocated based on fair values to the lease components and non-lease components. Although separation of lease and non-lease components is required, certain practical expedients are available to entities. Entities electing the practical expedient would not separate lease and non-lease components. Rather, they would account for each lease component and the related non-lease component together as a single component. The Company has elected to use this practical expedient for its real estate leases and account for each lease component and related non-lease component as one single component. In contrast, the Company has elected not to apply the practical expedient for its lease of manufacturing space at Patheon and has instead allocated consideration between the lease and non-lease components of the contract. The Company calculated the fair value of the lease component using publicly available information to identify comparable rentals in the same geographic area. The remainder of the consideration was allocated to the non-lease components. |

Fair Value of Financial Assets and Liabilities | 3. The following tables present information about the Company’s assets that are measured at fair value on a recurring basis as of June 30, 2020 and December 31, 2019 and indicate the level of the fair value hierarchy utilized to determine such fair value: Fair Value Measurements as of June 30, 2020 Using: (In thousands) Level 1 Level 2 Level 3 Total Assets: Cash equivalents $ 86,241 $ — $ — $ 86,241 Marketable securities 7,993 9,516 — 17,509 $ 94,234 $ 9,516 $ — $ 103,750 Fair Value Measurements as of December 31, 2019 Using: (In thousands) Level 1 Level 2 Level 3 Total Assets: Cash equivalents $ — $ 69,733 $ — $ 69,733 Marketable securities — 54,407 — 54,407 $ — $ 124,140 $ — $ 124,140 As of June 30, 2020, the Company’s cash equivalents and marketable securities that are invested in money market funds, overnight repurchase contracts, and U.S. Treasury bills are valued using Level 1 inputs based on quoted prices for identical securities in active markets. The Company measures the fair value of certain marketable securities using Level 2 inputs and primarily relies on quoted prices in active markets for similar marketable securities. Amortization and accretion of discounts and premiums are recorded in other income. As of December 31, 2019, the Company’s cash equivalents and marketable securities were classified within Level 2 of the fair value hierarchy. The Company had a term loan outstanding under its 2015 credit facility with MidCap Financial Funding XIII Trust and Silicon Valley Bank (the “2015 term loan”). On August 2, 2019, the Company entered into an amended and restated credit and security agreement with Silicon Valley Bank as agent, MidCap Financial Trust, and Flexpoint MCLS Holdings, LLC (collectively, the “Lenders”), providing for a term loan of $40.0 million (the “2019 term loan”) and a revolving credit facility of up to $20.0 million. The Company concurrently borrowed the $40.0 million term loan and used $7.7 million of the proceeds to repay the remaining amount owed on the 2015 term loan. In February 2020, the Company drew down the full $20.0 million available under the revolving credit facility. On May 18, 2020, the Company entered into an amendment to the amended and restated credit and security agreement (the “amendment”). Pursuant to the amendment, the Company borrowed $15.0 million under a new term loan advance and immediately used the proceeds to repay an equal amount under the revolving credit facility, and the maximum principal amount of the revolving credit facility was reduced from $20.0 million to $5.0 million. The new term loan is subject to substantially the same terms, including interest rate, amortization and maturity date, as the existing term loan under the credit facility. On May 2, 2017 the Company issued 3.375% convertible senior notes due 2024 (the “2024 Convertible Notes”) with embedded conversion features. The Company estimated the fair value of the 2024 Convertible Notes using a discounted cash flow approach to derive the value of a debt instrument using the expected cash flows and the estimated yield related to the convertible notes. The significant assumptions used in estimating the expected cash flows were: the estimated market yield based on an implied yield and credit quality analysis of a term loan with similar attributes, and the average implied volatility of the Company’s traded and quoted options available as of May 2, 2017. The Company recorded approximately $136.7 million as the fair value of the liability on May 2, 2017, with a corresponding amount recorded as a discount on the initial issuance of the 2024 Convertible Notes of approximately $64.5 million. The debt discount was recorded to equity and is being amortized to the debt liability over the life of the 2024 Convertible Notes using the effective interest method. The fair value of the 2024 Convertible Notes, which differs from their carrying value, is influenced by interest rates, stock price and stock price volatility and is determined by prices for the 2024 Convertible Notes observed in market trading. The market for trading of the 2024 Convertible Notes is not considered to be an active market and therefore the estimate of fair value is based on Level 2 inputs. The estimated fair value of the 2024 Convertible Notes, face value of $201.3 million, was $171.9 million at June 30, 2020. |

Debt | 9. Debt Amended and Restated Credit and Security Agreement Term Loan On August 4, 2015, the Company entered into a credit and security agreement with MidCap Financial Trust, as agent, and MidCap Financial Funding XIII Trust and Silicon Valley Bank, as lenders, to borrow up to $30.0 million in term loans. On August 2, 2019, the Company terminated the credit and security agreement and concurrently entered into an amended and restated credit and security agreement (the “amended and restated credit and security agreement”) with Silicon Valley Bank as agent, MidCap Financial Trust, Flexpoint MCLS Holdings, LLC, and the other lenders from time to time party thereto (collectively, the “Lenders”), providing for a term loan of $40.0 million and a revolving credit facility of up to $20.0 million, both of which mature on January 1, 2024 (the “Maturity Date”). The Company concurrently borrowed the $40.0 million term loan and used $7.7 million of the proceeds to repay the remaining amount owed on the 2015 term loan. The Company granted the Lenders a security interest in substantially all of its personal property, rights and assets, other than intellectual property, to secure the payment of all amounts owed under the amended and restated credit and security agreement. The Company agreed not to encumber any of its intellectual property without the Lenders’ prior written consent. The amended and restated credit and security agreement contains certain representations, warranties, and covenants of the Company, including a minimum revenue covenant that will be in effect at any time the Company’s liquidity (defined as cash and cash equivalents held with Silicon Valley Bank) is below $80.0 million. Additionally, if the Company’s liquidity is below $80.0 million, all amounts received from customer collections will be applied immediately to reduce the revolving credit facility. The revenue covenant is set annually and is based on the greater of a conservative percentage of the year’s approved forecast and modest growth over the trailing twelve months of actual revenues. On May 18, 2020, the Company entered into an amendment to the amended and restated credit and security agreement. Pursuant to the amendment, the Company borrowed $15.0 million under a new term loan advance and immediately used the proceeds to repay an equal amount under the revolving credit facility, and the maximum principal amount of the revolving credit facility was reduced from $20.0 million to $5.0 million. The new term loan is subject to substantially the same terms, including interest rate, amortization and maturity date, as the existing term loan under the credit facility. Under the credit facility, as amended, the Company remains subject to a minimum liquidity threshold, such that at any time the Company’s liquidity is below $80.0 million, the Company will become subject to a minimum revenue covenant. However, pursuant to the amendment, the Company’s liquidity now includes certain accounts receivable as deemed eligible under the credit and security agreement, in addition to cash, cash equivalents, and marketable securities. Prior to May 2021, the minimum revenue covenant, if it applies in the future, is unmodified and is based on the greater of (i) a conservative percentage of the year’s approved forecast and (ii) modest growth over the trailing twelve months of actual revenues. Beginning in May 2021, the minimum revenue covenant, if it applies, will be the greatest of (i) a conservative percentage of the year’s approved forecast, (ii) modest growth over the trailing twelve months of actual revenues and (iii) 100% of the minimum revenue covenant amount for the preceding month. Also pursuant to the amendment, the final payment due upon repayment or maturity of the term loans was changed from 4.75% of the term loan amount to 6.75% of the term loan amount. The amended and restated credit and security agreement also has a material adverse event clause. If the revenue covenant becomes applicable and the Company fails to comply with it, or a material adverse change as defined in the agreement occurs, the amounts due under the amended and restated credit and security agreement could be declared immediately due and payable. Borrowings under the 2019 term loan accrue interest monthly at a floating interest rate equal to the greater of the prime rate plus 1.5% or 6.5% per annum. Following an interest-only period of 18 months, principal is due in 36 equal monthly installments commencing February 1, 2021 and ending on the Maturity Date. Upon the Maturity Date, the Company will be obligated to pay a final payment equal to 6.75% of the total principal amounts borrowed under the facility. The final payment amount is being accreted to the carrying value of the debt using the straight-line method, which approximates the effective interest method. As of June 30, 2020, the carrying value of the term loan was approximately $55.4 million, of which $7.6 million is due within 12 months and $47.8 million is due in greater than 12 months. The Company may prepay the term loan at any time by paying the outstanding principal balance, a final payment equal to 6.75% of the term loan amount, all accrued interest and a prepayment fee of 3% of the outstanding term loan amount if repaid in the first year, 2% of the outstanding term loan amount if repaid in the second year, and 1% of the outstanding term loan amount if repaid in the third year of the loan; no prepayment fee is required thereafter. As of June 30, 2020, annual principal and interest payments due under the 2019 term loan were as follows: Year Aggregate Minimum Payments (in thousands) 2020 2,138 2021 20,090 2022 20,371 2023 19,117 2024 5,249 Thereafter — Total $ 66,965 Less interest (8,252 ) Less unamortized portion of final payment (3,245 ) Total $ 55,468 Revolving Credit Facility Borrowings under the revolving credit facility accrue interest monthly at a floating interest rate equal to the greater of the prime rate or 5.50% per annum. In addition to paying interest on any amounts borrowed under the revolving credit facility, the Company owes an unused revolving line facility fee equal to 0.25% per annum of the average unused portion of the revolving line, multiplied by the difference between the total amount available to be borrowed (the “Revolving Commitment Amount”) and the greater of the average outstanding revolver balance and 25% of the Revolving Commitment Amount. The revolving credit facility and any related fees or interest payments became available to the Company beginning January 1, 2020, and in February 2020, the Company drew down the $20.0 million available. On May 18, 2020, in connection with the amendment to the amended and restated credit and security agreement, the Company repaid $15.0 million, reducing the outstanding principal balance on the revolver to $5.0 million , and the maximum principal amount of the revolving credit facility was reduced from $20.0 million to $5.0 million Beginning on January 1, 2020, if the interest payment on the revolving credit facility is less than the amount of interest that would have been payable had the Company borrowed 25% of the Revolving Commitment Amount, then the Company will be required to pay the difference. The Company may retire the revolving credit facility early, at any time, by paying the outstanding principal balance, all accrued interest and a termination fee equal to 2% of the Revolving Commitment Amount if repaid in the first year, and 1% of the Revolving Commitment Amount if repaid in the second year; with no termination fee thereafter. 2024 Convertible Notes On May 2, 2017 the Company issued an aggregate of $201.3 million principal amount of the 2024 Convertible Notes. The 2024 Convertible Notes have a maturity date of May 1, 2024, are unsecured and accrue interest at a rate of 3.375% per annum, payable semi-annually on May 1 and November 1 of each year, beginning November 1, 2017. The Company received $194.8 million for the sale of the 2024 Convertible Notes, after deducting fees and expenses of $6.5 million. Upon conversion of the 2024 Convertible Notes, at the election of each holder of a 2024 Convertible Note (the Holder), the note will be convertible into cash, shares of the Company’s common stock, or a combination thereof, at the Company’s election (subject to certain limitations in the 2015 term loan), at a conversion rate of approximately 37.3413 shares of common stock per $1,000 principal amount of the 2024 Convertible Notes, which corresponds to an initial conversion price of approximately $ 26.78 per share of the Company’s common stock. The conversion rate is subject to adjustment from time to time upon the occurrence of certain events, including, but not limited to, fundamental change events and certain corporate events that occur prior to the maturity date of the notes. In addition, if the Company delivers a notice of redemption, the Company will increase, in certain circumstances, the conversion rate for a Holder who elects to convert its notes in connection with such a corporate event or notice of redemption, as the case may be. At any time prior to the close of business on the business day immediately preceding February 1, 2024, Holders may convert all, or any portion, of the 2024 Convertible Notes at their option only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2017 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any ten consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; (3) if the Company calls any or all of the notes for redemption, at any time prior to the close of business on the business day immediately preceding the redemption date; and (4) upon the occurrence of specified corporate events. On or after February 1, 2024, until the close of business on the business day immediately preceding the maturity date, Holders may convert their notes at any time, regardless of the foregoing circumstances. The Company may redeem, for cash, all or any portion of the 2024 Convertible Notes, at its option, on or after May 6, 2020 if the last reported sale price of the Company’s common stock has been at least 130% of the conversion price for at least 20 trading days during any 30 consecutive day trading period, at a redemption price equal to 100% of the principal amount of the 2024 Convertible Notes to be redeemed, plus accrued and unpaid interest, subject to the Holders’ right to convert as described above. The 2024 Convertible Notes are considered convertible debt with a cash conversion feature. Per ASC 470-20, Debt with Conversion and Other Options , The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature. The allocation was performed in a manner that reflected our non-convertible debt borrowing rate for similar debt. The equity component of the 2024 Convertible Notes was recognized as a debt discount and represents the difference between the proceeds from the issuance of the 2024 Convertible Notes and the fair value of the liability of the 2024 Convertible Notes on their respective dates of issuance. The excess of the principal amount of the liability component over its carrying amount (“debt discount”) is amortized to interest expense using the effective interest method over seven years. The equity component is not re-measured as long as it continues to meet the conditions for equity classification. In connection with the issuance of the 2024 Convertible Notes, the Company incurred approximately $6.5 million of debt issuance costs, which primarily consisted of underwriting, legal and other professional fees, and allocated these costs to the liability and equity components based on the allocation of the proceeds. Of the total d ebt issuance costs, $4.4 million was allocated to the liability component equity component and is recorded as a reduction to additional paid-in capital. Debt discount and issuance rate three and six months ended June 30, 2020 respectively, $2.2 million and $4.3 million, respectively, The table below summarizes the carrying value of the 2024 Convertible Notes as of June 30, 2020: ( in thousands Gross proceeds $ 201,250 Portion of proceeds allocated to equity component (additional paid-in capital) (64,541 ) Debt issuance costs (6,470 ) Portion of issuance costs allocated to equity component (additional paid-in capital) 2,075 Amortization of debt discount and debt issuance costs 25,676 Carrying value 2024 Convertible Notes $ 157,990 |

Stock-Based Compensation | 10. Stock-Based Compensation Stock Option Valuation The fair value of each of the Company’s stock option grants is estimated on the date of grant using the Black-Scholes option-pricing model. Expected volatility is based on historical volatility of the Company’s common stock. The expected term of the Company’s stock options has been determined utilizing the “simplified” method for awards that qualify as “plain vanilla” options. The expected term of stock options granted to non-employees is equal to the contractual term of the option award. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future. The relevant data used to determine the value of the stock option grants for the three and six months ended June 30, 2020 and 2019 were as follows: Three months ended Six months ended June 30, June 30, 2020 2019 2020 2019 Risk-free interest rates 0.51-0.56% 1.89 - 2.41% 0.51 - 1.79% 1.89 - 2.67% Expected dividend yield 0.00% 0.00% 0.00% 0.00% Expected term (in years) 6.0 6.0 6.0 6.0 Expected volatility 70.3 - 72.3% 68.6 - 68.9% 65.4 - 72.3% 68.6 - 69.5% The following table summarizes stock option activity for the six months ended June 30, 2020: (In thousands, except per share amounts) Shares Under Weighted Average Exercise Per Share Outstanding as of December 31, 2019 4,775 $ 17.99 Granted 420 14.98 Exercised (5 ) 12.88 Cancelled (263 ) 17.80 Outstanding as of June 30, 2020 4,927 $ 17.75 Options vested and expected to vest at June 30, 2020 4,927 $ 17.75 Options exercisable at June 30, 2020 3,381 $ 18.13 The aggregate intrinsic value of options is calculated as the difference between the exercise price of the options and the fair value of the Company’s common stock for those options that had exercise prices lower than the fair value of the Company’s common stock. Options to purchase a total of 4,691 shares of the Company’s common stock, with an aggregate intrinsic value of approximately $15,139, were exercised during the six months ended June 30, 2020. At June 30, 2020 and 2019, there were options for the purchase of approximately 4,926,718 and 4,972,362 shares of the Company’s common stock outstanding, respectively, with a weighted average remaining contractual term of 6.7 years and 7.2 years, respectively, and with a weighted average exercise price of $17.75 and $18.23 per share, respectively. The weighted average grant date fair value of options granted during the six months ended June 30, 2020 and 2019 was $8.94 and $8.78 per share, respectively. Restricted Stock Units During the six months ended June 30, 2020, the Company awarded 953,375 RSUs to employees at an average grant date fair value of $11.61 per share. The majority of the RSUs vest in four substantially equal installments on each of the first four anniversaries of the vesting commencement date, subject to the employee’s continued employment with, or services to, the Company on each vesting date. Compensation expense is recognized on a straight-line basis. Included in the 2020 RSU awards is a grant of 175,000 RSUs to the Company’s Chief Executive Officer. These RSUs have a performance condition in that they will only vest if the Company reaches a certain revenue threshold at December 31, 2020. If the threshold is reached, the vesting schedule will be the same as RSUs granted to other employees. As of June 30, 2020, the Company concluded that it was not probable that the performance condition would be met. Therefore, no expense has been recognized on these awards during the six months ended June 30, 2020. The following table summarizes the RSU activity for the six months ended June 30, 2020: (In thousands, except per share amounts) Number of Shares Weighted Average Grant Date Fair Value Per Share Nonvested balance as of December 31, 2019 853 $ 15.84 Granted 953 11.61 Vested/Released (209 ) 16.44 Cancelled (122 ) 14.86 Nonvested Balance as of June 30, 2020 1,475 $ 13.11 Stock-based Compensation The Company recorded stock-based compensation expense related to stock options and RSUs and shares purchased under the Employee Stock Purchase Plan for the three and six months ended June 30, 2020 and 2019 as follows: For the three months ended June 30, For the six months ended June 30, (In thousands) 2020 2019 2020 2019 Research and development $ 1,087 $ 1,385 $ 3,289 $ 2,541 Selling, general and administrative 2,700 2,832 5,149 5,529 Total $ 3,787 $ 4,217 $ 8,438 $ 8,070 As of June 30, 2020, unrecognized stock-based compensation expense for stock options outstanding was approximately $15.5 million which is expected to be recognized over a weighted average period of 2.3 years. As of June 30, 2020, unrecognized stock-based compensation expense for RSUs outstanding was $17.1 million which is expected to be recognized over a period of 2.9 years. |

Commitments And Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | 12. Operating Leases Burlington Lease The Company leases approximately 36,500 square feet of office space in Burlington, Massachusetts under a lease that began in May 2013 and was originally scheduled to expire on October 31, 2023 (the “Lease”). Upon adoption of ASU 2016-02, the Company recorded a right-of-use asset and corresponding lease liability for the Lease on January 1, 2019, by calculating the present value of lease payments, discounted at 8.9%, the Company’s estimated incremental borrowing rate, over the 4.8-year remaining term. In June 2019, the Company amended the Lease to add approximately 5,330 square feet of additional office space and extend the term of the Lease through April 30, 2025 (the “Amended Lease”). As a result of the Amended Lease, the total rentable floor area is 41,873 square feet. Starting in August 2019, the Company’s minimum monthly lease payment is approximately $108,000, which increases over the term of the Amended Lease. In addition to the base rent for the office space, the Company is responsible for its share of operating expenses and real estate taxes. The lease commencement date for the additional space, which represents the date the Company first had access to the space, was July 1, 2019. The Company accounted for the Amended Lease as a lease modification that is a separate contract from the original lease and recorded an incremental right-of-use asset and lease liability of $2.5 million, which represents the present value of the lease payments relating to the new space, as well as the lease payments relating to the 18-month extension of the existing space, as of the modification date, discounted at 6.8%. The straight-line lease cost for the Amended Lease (including the expense relating to the original Lease) amounted to $0.4 million and $0.9 million, respectively, for the three and six months ended June 30, 2020, and was included in operating expenses. As of June 30, 2020, the remaining lease term on the Amended Lease was 4.8 years, which includes the 18-month extension resulting from the amendment signed in June 2019. Woburn Lease In February 2017, the Company entered into a five-year Upon adoption of ASU 2016-02, the Company recorded a right-of-use asset and corresponding lease liability for the Lease on January 1, 2019, by calculating the present value of lease payments, discounted at 8.4%, the Company’s estimated incremental borrowing rate, over the 3.2-year remaining term. The Woburn lease includes an option to extend the term of the lease for two years. Since the Company adopted ASU 2016-02 using the Comparatives under 840 approach, it did not reassess the determination of its operating leases as leases, and therefore no options to extend the lease were included in the calculation of the lease liability as of June 30, 2020. The straight-line lease cost for the Woburn lease amounted to $46,000 and $92,000, respectively, for the three and six months ended June 30, 2020, and was included in operating expenses. As of June 30, 2020, the remaining lease term on the Woburn lease was 1.7 years. Manufacturing and Supply Agreement with Patheon UK Limited In July 2015, the Company and Patheon UK Limited (“Patheon”) entered into a Manufacturing and Supply Agreement (the “Manufacturing Agreement”) and Technical Transfer and Service Agreement (the “Technical Transfer Agreement”) for the manufacture of ZILRETTA. Patheon agreed in the Technical Transfer Agreement to undertake certain transfer activities and construction services needed to prepare Patheon’s United Kingdom facility for the commercial manufacture of ZILRETTA in dedicated manufacturing suites. The Company provided Patheon with certain equipment and materials necessary to manufacture ZILRETTA and pays Patheon a monthly fee for such activities and reimburses Patheon for certain material, equipment and miscellaneous expenses and additional services. The initial term of the Manufacturing Agreement is 10 years from approval by the FDA of the Patheon manufacturing suites for ZILRETTA, or until October 6, 2027. The Company pays a monthly base fee to Patheon for the operation of the manufacturing suites and a per product fee for each vial based upon a forecast of commercial demand. The Company also reimburses Patheon for purchases of materials and equipment made on its behalf, certain nominal expenses and additional services. The Manufacturing Agreement will remain in full effect unless and until it expires or is terminated. Upon termination of the Manufacturing Agreement (other than termination by Flexion in the event that Patheon does not meet the construction and manufacturing milestones or for a breach by Patheon), Flexion will be obligated to pay for the costs incurred by Patheon associated with the removal of Flexion’s manufacturing equipment and for Patheon’s termination costs up to a capped amount. The Manufacturing Agreement with Patheon contains an operating lease for the use of dedicated manufacturing suites. With the adoption of ASU 2016-02, the Company recorded a right-of-use asset and corresponding lease liability for the operating lease. In June 2019, the Company and Patheon amended the Manufacturing Agreement and the Technical Transfer Agreement. The amendment primarily modifies the compensation structure, which is comprised of base fees and per product fees the Company pays to Patheon and does not result in any additional rights of use. The Company accounted for the amendment as a lease modification that is not a separate contract from the original lease. As part of the modification, the Company reassessed whether the contract is or contains a lease and determined that there is an operating lease component for the use of dedicated manufacturing suites. The remainder of the consideration is allocated to the service component. The Company also reassessed the lease liability by calculating the present value of the remaining lease payments as of the modification date, discounted at 6.1%. The modification resulted in an increase to each of the lease liability and right of use asset of $0.5 million. In April 2020, the Company entered into a side letter amending the Manufacturing Agreement with Patheon pursuant to which the parties agreed that the Company would continue to pay the monthly base fee for maintaining the manufacturing suites, but minimum purchase obligations would be cancelled for 2020 as the Company temporarily suspended manufacturing activities for ZILRETTA. In June 2020, the Company informed Patheon of its intent to restart manufacturing in the fourth quarter. The amendment did not change the amount of fixed consideration owed to Patheon over the life of the contract, nor did it grant the Company any additional rights of use. As such, there was no change in the accounting for the embedded lease as a result of this amendment. As of June 30, 2020, the remaining lease term on the Patheon lease was 7.3 years. The straight-line lease cost amounted to $55 The components of lease expense and related cash flows were as follows: (In thousands) For the three months ended June 30, For the six months ended June 30, Operating lease cost 2020 2019 2020 2019 Operating lease cost included in operating expenses $ 514 $ 369 $ 1,027 $ 738 Operating lease cost included in inventory 55 48 113 93 Total operating lease cost 569 417 1,140 831 Operating cash flows from operating leases 739 590 1,557 1,094 Maturities of lease liability due under these lease agreements as of June 30, 2020 were as follows: Year Operating Lease Obligations (in thousands) 2020 $ 989 2021 2,018 2022 1,865 2023 1,873 2024 1,915 Thereafter 1,180 Present value of imputed interest (2,418 ) Total $ 7,422 Other Commitments and Contingencies Evonik Supply Agreement In November 2016, the Company entered into a Supply Agreement with Evonik Corporation (“Evonik”) for the purchase of PLGA which is used in the manufacturing of clinical and commercial supply of ZILRETTA. Pursuant to the Supply Agreement, Flexion is obligated to submit rolling monthly forecasts to Evonik for PLGA supply, a portion of which will constitute binding orders. In addition, Flexion agreed to certain minimum purchase requirements, which do not apply (i) during periods in which Evonik is in material breach of the Supply Agreement or is unable to perform its obligations due to a force majeure event, (ii) with respect to orders that Evonik is unable to supply in excess of binding orders, (iii) for orders Evonik is unable to timely deliver or does not deliver conforming product and provides a credit for such order, or (iv) during an uncured material quality failure by Evonik. Flexion agreed to purchase PLGA batches at a specified price per gram in U.S. dollars, subject to adjustment from time to time, including due to changes in price indices and in the event the initial term of the Supply Agreement is extended. The total term of the agreement is five years. Upon termination of the Supply Agreement (other than termination due to the bankruptcy of either Evonik or Flexion) Flexion is obligated to pay the costs associated with the binding supply forecast provided to Evonik. The Supply Agreement will renew for two successive two year terms upon mutual written consent by both parties. FX201 Related Agreement s In December 2017, the Company entered into a definitive agreement with GeneQuine Biotherapeutics GmbH (“GeneQuine”) to acquire the global rights to FX201. As part of the asset purchase transaction with GeneQuine, the Company made an upfront payment to GeneQuine of $2.0 million. In 2018, the Company paid GeneQuine $750,000 for the milestone of initiating a GLP toxicology study of FX201. In addition, the Company paid GeneQuine a $750,000 payment in November 2019 following the FDA acceptance of the IND application for FX201. The next milestone of $2.5 million was achieved in March 2020 when the first patient was treated in the Phase 1 clinical trial. This milestone was recognized as research and development expense in the first quarter of 2020. The Company may also be required to make additional milestone payments during the development of FX201, including up to $4.5 million for the initiation of a Phase 2 Proof of Concept (PoC), clinical trial and, following successful PoC, up to an additional $51.5 million in development and global regulatory approval milestone payments. The transaction was accounted for as an asset acquisition, as it did not qualify as a business combination. The upfront fee was attributed to the intellectual property acquired and recognized as research and development expense in December 2017 as the FX201 product candidate had not been commercially approved and had no alternative future use. The milestone payments for the GLP toxicology study and the acceptance of the IND were also recorded to research and development expense in the fourth quarters of 2018 and 2019, respectively. Future milestone payments earned prior to regulatory approval of FX201 would be recognized as research and development expense in the period when the milestone events become probable of being achieved. Future milestones earned upon regulatory approval would be recognized as an intangible asset and amortized to expense over its estimated life. As of June 30, 2020, no other milestones under the arrangement were probable of being achieved. As part of the transaction, the Company became the direct licensee of certain underlying Baylor College of Medicine (Baylor) patents and other proprietary rights related to FX201 for human applications. The Baylor license agreement grants the Company an exclusive, royalty-bearing, world-wide right and license (with a right to sublicense) for human applications under its patent and other proprietary rights directly related to FX201, with a similar non-exclusive license to certain Baylor intellectual property rights that are not specific to FX201. The license agreement with Baylor includes a low single-digit royalty on net sales of FX201 and requires the Company to use reasonable efforts to develop FX201 according to timelines set out in the license agreement. In December 2017, the Company also entered into a Master Production Services Agreement with SAFC Carlsbad, Inc., a part of MilliporeSigma, for the manufacturing of preclinical and initial clinical supplies of FX201. FX301 Related Agreements In September 2019, the Company entered into a definitive agreement with Xenon Pharmaceuticals, Inc. (“Xenon”) that provides the Company with the global rights to develop and commercialize XEN402, Xenon’s NaV1.7 inhibitor known as funapide, formulated for extended release with a novel, Flexion proprietary thermosensitive hydrogel under the Company’s preclinical program known as FX301. The transaction was accounted for as an asset acquisition, as it did not qualify as a business combination. As part of the asset purchase transaction with Xenon, the Company made an upfront payment to Xenon of $3.0 million. The upfront fee was attributed to the intellectual property acquired and was recognized as research and development expense in September 2019 as the FX301 product candidate had not been commercially approved and had no alternative future use. As of June 30, 2020, the Company concluded that the first milestone relating to the initiation of the first GLP toxicology study was probable of being achieved, as the GLP toxicology study commenced on April 13, 2020. The Company recorded a milestone payment of $500,000 to research and development expense in the first quarter of 2020. The Company may also be required to make additional milestone payments during the development of FX301, including up to $8.0 million through initiation of a Phase 2 proof of concept (PoC) clinical trial and, following successful PoC, up to $40.8 million in development and global regulatory approval milestone payments and up to an additional $75.0 million in sales-related milestone payments. Future milestone payments earned prior to regulatory approval of FX301 would be recognized as research and development expense in the period when the milestone events become probable of being achieved. Future milestones earned subsequent to regulatory approval would be recognized as an intangible asset and amortized to expense over the estimated life of FX301. As of June 30, 2020, no other milestones under the arrangement were probable of being achieved. As part of the transaction, the Company became the direct licensee of certain underlying Xenon patents and other proprietary rights related to XEN402 for human applications. The Xenon agreement grants the Company an exclusive, royalty-bearing, world-wide right and license (with a right to sublicense) for human applications under its patents directly related to XEN402, with a similar royalty-free license to other Xenon proprietary rights directly related to XEN402. The agreement with Xenon includes a tiered royalty ranging from mid-single digits to low double digits that is based on aggregate annual net sales of FX301 and requires the Company to use reasonable efforts to develop FX301 according to timelines set out in the agreement. |

Subsequent Events | 13. Subsequent Events On July 16, 2020, the Company’s Compensation Committee of the Board of Directors approved the grant of restricted stock units (“RSUs”) to substantially all the Company’s employees, including executive officers. The number of shares of the Company’s common stock subject to each RSU is generally equal to the employee’s target annual equity grant, except for the Company’s chief executive officer whose RSU grant was half of the target annual equity grant. The RSU’s granted to the Company’s executive officers vest in equal annual installments over a 3-year vesting period, while the RSUs granted to the Company’s non-executive employees vest 1/3rd on the one-year anniversary of the grant date and 2/3rds on the second-year anniversary of the grant date. |

Revenue Recognition | Revenue Recognition On October 6, 2017, the U.S. Food and Drug Administration, (FDA), approved ZILRETTA. The Company entered into a limited number of arrangements with specialty distributors and a specialty pharmacy in the U.S. to distribute ZILRETTA. The Company recognizes revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606 - Revenue from Contracts with Customers (“Topic 606”). Under Topic 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to be entitled to in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of Topic 606, the entity performs the following five steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to arrangements that meet the definition of a contract with a customer under Topic 606, including when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of Topic 606, the Company assesses the goods or services promised within each contract, determines those that are performance obligations, and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Product Revenue, Net — The Company primarily sells ZILRETTA to specialty distributors and a specialty pharmacy, who then subsequently resell ZILRETTA to physicians, clinics and certain medical centers or hospitals. The Company also contracts directly with healthcare providers and intermediaries such as Group Purchasing Organizations (“GPOs”). In addition, the Company enters into arrangements with government payers that provide for government mandated rebates and chargebacks with respect to the purchase of ZILRETTA. The Company recognizes revenue on product sales when the customer obtains control of the Company's product, which occurs at a point in time (upon delivery to the customer). The Company has determined that the delivery of ZILRETTA to its customers constitutes a single performance obligation. There are no other promises to deliver goods or services beyond what is specified in each accepted customer order. The Company has assessed the existence of a significant financing component in the agreements with its customers. The trade payment terms with customers do not exceed one year and therefore the Company has elected to apply the practical expedient and no amount of consideration has been allocated as a financing component. Product revenues are recorded net of applicable reserves for variable consideration, including discounts and allowances. Transaction Price, including Variable Consideration — Revenues from product sales are recorded at the net sales price (transaction price), which includes estimates of variable consideration for which reserves are established. Components of variable consideration include trade discounts and allowances, product returns, government chargebacks, discounts and rebates, and other incentives, such as voluntary patient assistance, and other fee for service amounts that are detailed within contracts between the Company and its customers relating to the Company’s sale of its products. These reserves, as detailed below, are based on the amounts earned, or to be claimed on the related sales, and are classified as reductions of accounts receivable (if the amount is payable to the customer) or a current liability (if the amount is payable to a party other than a customer). These estimates take into consideration a range of possible outcomes which are probability-weighted in accordance with the expected value method in Topic 606 for relevant factors such as current contractual and statutory requirements, specific known market events and trends, industry data, and forecasted customer buying and payment patterns. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the respective underlying contracts. The amount of variable consideration which is included in the transaction price may be constrained and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized under the contract will not occur in a future period. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results in the future vary from the Company’s original estimates, the Company will adjust these estimates, which would affect net product revenue and earnings in the period such variances become known. Service Fees and Allowances — The Company compensates its customers and GPOs for sales order management, data, and distribution services. However, the Company has determined such services received to date are not distinct from the Company’s sale of products to the customer and, therefore, these payments have been recorded as a reduction of revenue within the statement of operations and comprehensive loss through June 30, 2020, as well as a reduction to trade receivables, net on the condensed consolidated balance sheets. Product Returns — Consistent with industry practice, the Company generally offers customers a limited right of return for product that has been purchased from the Company based on the product’s expiration date. The Company estimates the amount of its product sales that may be returned by its customers and records this estimate as a reduction of revenue in the period the related product revenue is recognized, as well as within accrued expenses and other current liabilities, net, on the condensed consolidated balance sheets. The Company currently estimates product return liabilities using available industry data and its own sales information, including its visibility into the inventory remaining in the distribution channel. The Company has received an immaterial amount of returns to date and believes that future returns of ZILRETTA will be minimal. Chargebacks — Chargebacks for fees and discounts to qualified government healthcare providers represent the estimated obligations resulting from contractual commitments to sell products to qualified VA hospitals and 340b entities at prices lower than the list prices charged to customers who directly purchase the product from the Company. The 340b Drug Discount Program is a U.S. federal government program created in 1992 that requires drug manufacturers to provide outpatient drugs to eligible health care organizations and covered entities at significantly reduced prices. Customers charge the Company for the difference between what they pay for the product and the statutory selling price to the qualified government entity. These reserves are established in the same period that the related revenue is recognized, resulting in a reduction of product revenue and trade receivables, net. Chargeback amounts are generally determined at the time of resale to the qualified government healthcare provider by customers, and the Company generally issues credits for such amounts within a few weeks of the customer’s notification to the Company of the resale. Reserves for chargebacks consist of credits that the Company expects to issue for units that remain in the distribution channel inventories at each reporting period-end that the Company expects will be sold to qualified healthcare providers, and chargebacks that customers have claimed, but for which the Company has not yet issued a credit. Government Rebates — The Company is subject to discount obligations under state Medicaid programs and Medicare. These reserves are recorded in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability which is included in accrued expenses and other current liabilities on the condensed consolidated balance sheets. For Medicare, the Company also estimates the number of patients in the prescription drug coverage gap for whom the Company will owe an additional liability under the Medicare Part D program. The Company estimates its exposure to utilization from the Medicare Part D coverage gap discount program to be immaterial. For Medicaid programs, the Company estimates the portion of sales attributed to Medicaid patients and records a liability for the rebates to be paid to the respective state Medicaid programs. The Company’s liability for these rebates consists of invoices received for claims from prior quarters that have not been paid or for which an invoice has not yet been received, estimates of claims for the current quarter, and estimated future claims that will be made for product that has been recognized as revenue, but which remains in the distribution channel inventories at the end of each reporting period. Purchaser/Provider Discounts and Rebates — Beginning in the third quarter of 2019, the Company began offering rebates to eligible purchasers and healthcare providers that are variable based on volume of product purchased. Rebates are based on actual purchase levels during the rebate purchase period. The Company estimates these rebates and records such estimates in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability. Other Incentives — Other incentives which the Company offers include voluntary patient assistance programs, such as the co-pay assistance program, which are intended to provide financial assistance to qualified commercially-insured patients with prescription drug co-payments required by payers. The calculation of the accrual for co-pay assistance is based on an estimate of claims and the cost per claim that the Company expects to receive associated with product that has been recognized as revenue, but remains in the distribution channel inventories at the end of each reporting period. The adjustments are recorded in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability which is included as a component of accrued expenses and other current liabilities on the condensed consolidated balance sheets. To date, the Company’s only source of product revenue has been from the U.S. sales of ZILRETTA, which it began shipping to customers in October 2017. The following table summarizes activity in each of the product revenue allowance and reserve categories for the three and six months ended June 30, 2020 and 2019: (In thousands) Service Fees, Allowances and Chargebacks Government Rebates and Other Incentives Product Returns Purchaser/Provider Discounts and Rebates Total Balance as of December 31, 2019 $ 1,847 $ 248 $ 402 $ 1,656 $ 4,153 Provision related to sales in the current quarter 1,590 254 114 526 2,484 Credits and payments made (1,852 ) (199 ) (10 ) (1,656 ) (3,717 ) Adjustments related to prior period sales — 95 — — 95 Balance as of March 31, 2020 1,585 398 506 526 3,015 Provision related to sales in the current quarter 1,417 133 98 892 2,540 Credits and payments made (1,172 ) (262 ) (1 ) (528 ) (1,963 ) Adjustments related to prior period sales — 90 — 2 92 Balance as of June 30, 2020 $ 1,830 $ 359 $ 603 $ 892 $ 3,684 Balance as of December 31, 2018 $ 601 $ 491 $ 125 $ — $ 1,217 Provision related to sales in the current quarter 741 24 57 — 822 Credits and payments made (332 ) (36 ) (33 ) — (401 ) Balance as of March 31, 2019 1,010 479 149 — 1,638 Provision related to sales in the current quarter 1,196 121 92 — 1,409 Credits and payments made (1,157 ) (65 ) (6 ) — (1,228 ) Balance as of June 30, 2019 $ 1,049 $ 535 $ 235 $ — $ 1,819 License Agreement – On March 30, 2020, the Company entered into an exclusive license agreement with Hong Kong Tainuo Pharma Ltd. (“HK Tainuo”) and Jiangsu Tainuo Pharmaceutical Co. Ltd. (“Jiangsu Tainuo”), a subsidiary of China Shijiazhuang Pharmaceutical Co, Ltd. for the development and commercialization of ZILRETTA in Greater China (consisting of mainland China, Hong Kong and Macau, and Taiwan). Under the terms of the agreement, HK Tainuo is obligated to pay the Company an upfront payment of $10.0 million. The Company is also eligible to receive up to $32.5 million in aggregate development, regulatory and commercial sales milestone payments. All payments received from HK Tainuo are subject to the applicable Hong Kong withholding taxes. HK Tainuo will be responsible for the clinical development, product registration and commercialization of ZILRETTA in Greater China and Jiangsu Tainuo will serve as the guarantor of HK Tainuo’s obligations and responsibilities under the agreement. The Company is solely responsible for the manufacture and supply of ZILRETTA to HK Tainuo for all clinical and commercial activities. The terms related to product manufacturing and supply, including pricing and minimum purchase requirements agreed to in the license agreement, will be covered by a separate supply agreement. All amounts owed to the Company are nonrefundable and non-creditable once paid. Unless terminated earlier in accordance with its terms, the license agreement continues in effect in perpetuity or as long as HK Tainuo or Jiangsu Tainuo continue to sell ZILRETTA in Greater China. Either party may terminate the agreement prior to expiration in the event of a material breach if not cured within 60 days from the date of notice of such breach (30 days in the case of payment obligations), or either party files for bankruptcy. The Company also has the right to terminate the agreement if HK Tainuo, Jiangsu Tainuo or any affiliate of each, commences any action or proceeding that challenges the validity, enforceability or scope of any Company patent in Greater China. Upon any such termination, the license granted to HK Tainuo will terminate and all know-how and patents will revert back to the Company. The revenue related to the upfront payment of $10.0 million, of which $5.0 million was received as of June 30, 2020 and the remaining $5.0 million is due in the third quarter of 2020, will be recognized as the Company’s supply obligation is fulfilled over the term of the supply agreement, which has not yet commenced. The Company concluded that the license and supply performance obligations were not distinct, and therefore the transaction price will be recognized as revenue over the period that the Company performs its supply obligations. revenue was recognized associated with this contract as of June 30, 2020 . |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that may affect the reported amounts of assets and liabilities, revenue and expenses and related disclosures. The Company bases estimates and judgments on historical experience and on various other factors that it believes to be reasonable under the circumstances. The most significant estimates in these condensed consolidated financial statements include estimates related to revenue recognition and accrued expenses related to preclinical and clinical development costs. The Company’s actual results may differ from these estimates under different assumptions or conditions. The Company evaluates its estimates on an ongoing basis. Changes in estimates are reflected in reported results in the period in which they become known by the Company’s management. The full extent to which the COVID-19 pandemic will directly or indirectly impact the Company’s business, results of operations and financial condition, including sales, expenses, reserves and allowances, clinical trials, research and development costs and employee-related amounts, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain or treat it, as well as the economic impact on local, regional, national and international customers and markets. The Company has made estimates of the impact of COVID-19 within its financial statements and there may be changes to those estimates in future periods. |
Property and Equipment | Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Depreciation and amortization expense is recognized using the straight-line method over the following estimated useful lives: Estimated Useful Life (Years) Computers, office equipment, and minor computer software 3 Computer software 7 Manufacturing equipment 7-10 Furniture and fixtures 5 Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life of the related asset. Costs of major additions and improvements are capitalized and depreciated on a straight-line basis over their useful lives. Repairs and maintenance costs are expensed as incurred. Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is credited or charged to income. Property and equipment includes construction-in-progress that is not yet in service. |
Foreign Currencies | Foreign Currencies The Company maintains a bank account denominated in British Pounds. All foreign currency payables and cash balances are measured at the applicable exchange rate at the end of the reporting period. All associated gains and losses from foreign currency transactions are reflected in the consolidated statements of operations. |
Leases | Leases The Company determines if an arrangement is a lease at contract inception. Operating lease assets represent a right to use an underlying asset for the lease term and operating lease liabilities represent an obligation to make lease payments arising from the lease. Operating lease liabilities with a term greater than one year and their corresponding right-of-use assets are recognized on the balance sheet at the commencement date of the lease based on the present value of lease payments over the expected lease term. Certain adjustments to the right-of-use asset may be required for items such as initial direct costs paid or incentives received. The Company made an accounting policy election to expense leases with a term of one year or less on a straight-line basis over the lease term. To date, the Company has not identified any material short-term leases, either individually or in the aggregate. As the Company’s leases do not provide an implicit rate, the Company utilized the appropriate incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. The Company estimated the incremental borrowing rate based on a yield curve analysis of companies with a similar credit rating to its own, which was calculated using a number of financial ratios and qualitative considerations of the Company’s business. The yields on the Company’s currently outstanding debt (the 2024 Convertible Notes and term loan) were also used as inputs to the analysis to calculate a spread, adjusted for factors that reflect the profile of secured borrowing over the expected term of the lease. The components of a lease should be split into three categories: lease components (e.g., land, building, etc.), non-lease components (e.g., common area maintenance, utilities, performance of manufacturing services, purchase of inventory, etc.), and non-components (e.g., property taxes, insurance, etc.). Then the fixed contract consideration (including any related to non-components) must be allocated based on fair values to the lease components and non-lease components. Although separation of lease and non-lease components is required, certain practical expedients are available to entities. Entities electing the practical expedient would not separate lease and non-lease components. Rather, they would account for each lease component and the related non-lease component together as a single component. The Company has elected to use this practical expedient for its real estate leases and account for each lease component and related non-lease component as one single component. In contrast, the Company has elected not to apply the practical expedient for its lease of manufacturing space at Patheon and has instead allocated consideration between the lease and non-lease components of the contract. The Company calculated the fair value of the lease component using publicly available information to identify comparable rentals in the same geographic area. The remainder of the consideration was allocated to the non-lease components. |
