Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization and Basis of Presentation | Organization and Basis of Presentation Zogenix, Inc. and subsidiaries (the Company, we, us or our) is a global pharmaceutical company committed to developing and commercializing transformative therapies to improve the lives of patients and their families living with rare diseases. Our primary area of therapeutic focus is rare, or “orphan” childhood-onset epilepsy disorders. Our lead product candidate, Fintepla (ZX008, fenfluramine) is currently being developed for the treatment of seizures associated with Dravet syndrome and Lennox-Gastaut syndrome. We operate in one business segment—the research, development and commercialization of pharmaceutical products and our headquarters are located in Emeryville, California. Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of Zogenix, Inc. and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) for interim financial reporting. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. Certain reclassifications have been made to the prior period amounts to conform to the current year presentation. The results of operations for any interim period are not necessarily indicative of results of operations for any future period. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States (GAAP) have been condensed or omitted. Accordingly, these unaudited interim condensed consolidated financial statements and accompanying notes should be read in conjunction with the consolidated financial statements and related notes included in our 2018 Annual Report on Form 10-K, which was filed with the SEC on February 28, 2019. Certain prior period amounts within the accompanying unaudited consolidated financial statements have been reclassified to conform to current period presentation. These reclassifications did not affect our financial position, net loss, comprehensive loss, or cash flows as of and for the periods presented. Future Funding Requirements Excluding gains from two discrete business divestitures, we have incurred significant net losses and negative cash flows from operating activities resulting in an accumulated deficit of $731.2 million as of March 31, 2019. We expect to continue to incur significant operating losses and negative cash flows from operations as we continue to advance our product candidates through development and commercialization. Additionally, pursuant to our acquisition of Brabant Pharma Limited (Brabant) in 2014 to obtain worldwide development and commercialization rights to Fintepla, we are required to make additional payments to the former owners of Brabant in the event we achieve certain regulatory and sales milestones with Fintepla (See Note 5). Historically, we have relied primarily on the proceeds from equity offerings to finance our operations. Until such time, if ever, we can generate a sufficient amount of revenue to finance our cash requirements, we may need to continue to rely on additional financing to achieve our business objectives. However, if such financing is not available at adequate levels when needed, we may be required to significantly delay, scale back or discontinue one or more of the product development programs or commercialization efforts or other aspects of our business plans, and our operating results and financial condition would be adversely affected. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results may differ from those estimates. Revenue Recognition We analyze our collaboration agreements to assess whether such arrangements, or transactions between arrangement participants, involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities or are more akin to a vendor-customer relationship. In making this evaluation, we consider whether the activities of the collaboration are considered to be distinct and deemed to be within the scope of the collaboration guidance and those that are more reflective of a vendor-customer relationship and, therefore, within the scope of the revenue with contracts with customer guidance. This assessment is performed throughout the life of the arrangement based on changes in the responsibilities of all parties in the arrangement. For elements of collaboration arrangements that are not accounted for pursuant to the revenue from contracts with customer guidance, an appropriate recognition method is determined and applied consistently, generally by analogy to the revenue from contracts with customers guidance. Revenue from transactions with collaboration participants is presented apart from revenue with contracts with customers in our condensed consolidated statement of operations. Amounts received prior to satisfying the revenue recognition criteria are recorded as deferred revenue in the condensed consolidated balance sheets. If the related performance obligation is expected to be satisfied within the next twelve months this will be classified in current liabilities. Unconditional rights to receive consideration in advance of performance are recorded as receivables and deferred revenue in the condensed consolidated balance sheets when we have a contractual right to bill and receive the payment, performance is expected to commence shortly and there is less than a year between billing and performance. Amounts recognized for satisfied performance obligations prior to the right to payment becoming unconditional are recorded as contract assets in the condensed consolidated balance sheets. If we expect to have an unconditional right to receive consideration in the next twelve months, this will be classified in current assets. A net contract asset or liability is presented for each contract with a customer. For arrangements or transactions between arrangement participants determined to be within the scope of the contracts with customers guidance, we perform the following steps to determine the appropriate amount of revenue to be recognized as we fulfill our obligations: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated selling prices; and (v) recognition of revenue when (or as) we satisfy each performance obligation. At contract inception, we assess the goods or services promised in a contract with a customer and identifies those distinct goods and services that represent a performance obligation. A promised good or service may not be identified as a performance obligation if it is immaterial in the context of the contract with the customer, if it is not separately identifiable from other promises in the contract (either because it is not capable of being separated or because it is not separable in the context of the contract), or if the performance obligation does not provide the customer with a material right. We consider the terms of the contract and our customary business practices to determine the transaction price. The transaction price is the amount of consideration to which we expect to be entitled in exchange for transferring promised goods or services to a customer. The consideration promised in a contract with a customer may include fixed amounts, variable amounts, or both. Variable consideration will only be included in the transaction price when it is not considered constrained, which is when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. If it is determined that multiple performance obligations exist, the transaction price is allocated at the inception of the agreement to all identified performance obligations based on the relative stand-alone selling prices. The relative selling price for each deliverable is estimated using objective evidence if it is available. If objective evidence is not available, we use our best estimate of the selling price for the deliverable. Revenue is recognized when, or as, we satisfy a performance obligation by transferring a promised good or service to a customer. An asset is transferred when, or as, the customer obtains control of that asset, which for a service, is considered to be as the services are received and used. We recognize revenue over time by measuring the progress toward complete satisfaction of the relevant performance obligation using an appropriate input or output method based on the nature of the good or service promised to the customer. After contract inception, the transaction price is reassessed at every period end and updated for changes such as resolution of uncertain events. Any change in the transaction price is allocated to the performance obligations on the same basis as at contract inception. Management may be required to exercise considerable judgment in estimating revenue to be recognized. Judgment is required in identifying performance obligations, estimating the transaction price, estimating the stand-alone selling prices of identified performance obligations, which may include forecasted revenue, development timelines, reimbursement rates for personnel costs, discount rates and probabilities of technical and regulatory success, and estimating the progress towards satisfaction of performance obligations. Significant Accounting Policies Our other significant accounting policies are described in Note 2 of Notes to Consolidated Financial Statements included in our 2018 Annual Report on Form 10-K. As a result of entering into a collaborative arrangement in March 2019 and the adoption of the new lease accounting standard, we have updated our revenue recognition and lease accounting policies as detailed below. There were no other changes to our significant accounting policies from those disclosed in our 2018 Annual Report on Form 10-K. See Notes 3 and 7 for additional details related to our collaborative arrangement and the adoption of the new lease accounting standard, respectively. Recently Adopted Accounting Pronouncements ASU 2018-18, Collaboration Arrangements: Clarifying the Interaction between Topic 808 and Topic 606 makes targeted improvements for collaborative arrangements by (1) clarifying that certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606 when the collaboration arrangement participant is a customer, (2) adding unit of account guidance to assess whether the collaboration arrangement or a part of the arrangement is with a customer and (3) precluding a company from presenting transactions with collaboration arrangement participants that are not directly related to sales to third parties together with revenue from contracts with customers. On January 1, 2019, we early adopted this new standard and its applicability has been considered in the accounting for our collaborative arrangement with Nippon Shinyaku Co., Ltd. (See Note 3). Leases In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Topic 842 establishes a right-of-use asset model that requires all lessees to recognize ROU assets and liabilities for leases with a duration greater than one year on the balance sheet as well as provide disclosures with respect to certain qualitative and quantitative information regarding the amount, timing and uncertainty of cash flows arising from leases. On January 1, 2019, we adopted Topic 842 using the modified retrospective approach and elected the package of practical expedients permitted under transition guidance. Consequently, prior period financial information and related disclosures have not been adjusted and will continue to be presented in accordance with the previous lease standard. In addition, we elected the package of transition provisions available for existing contracts, which allowed us to carryforward our historical assessments of (1) whether contracts are or contain leases, (2) lease classification and (3) initial direct lease costs for existing leases. We did not elect the practical expedient allowing the use-of-hindsight which would require us to reassess the lease term of our leases based on all facts and circumstances through the effective date and did not elect the practical expedient pertaining to land easements as this is not applicable to the current contract portfolio. The adoption of Topic 842 did not have a material impact on our condensed consolidated statements of operations and cash flows. The impact on the accompanying condensed consolidated balance sheet as of January 1, 2019 was as follows (in thousands): December 31, 2018 Adjustments Due to the January 1, 2019 Assets Operating lease right-of-use assets $ — $ 8,641 $ 8,641 Liabilities Other accrued liabilities 1,845 (363) $ 1,482 Current portion of operating lease liabilities — 1,058 1,058 Operating lease liabilities, net of current portion — 11,776 11,776 Other long-term liabilities 3,830 (3,830) — Total 5,675 8,641 14,316 Upon adoption on January 1, 2019, we recorded operating lease ROU assets and lease liabilities of $8.6 million and $12.8 million, respectively, with the difference between ROU assets and lease liabilities attributed to the reclassifications of deferred rent and lease incentive obligations, a cease-use liability and initial direct leasing costs as a component of ROU assets. Prior to January 1, 2019, we recognized related rent expense on a straight-line basis over the term of the lease. Incentives granted under our operating lease, including allowances for leasehold improvements and rent holidays, were recognized as reductions to rent expense on a straight-line basis over the term of the lease. Deferred rent consisted of the difference between rent expense recognized on a straight-line basis and cash rent payments. Subsequent to the adoption of Accounting Standards Update (ASU) 2016-02 and related amendments (collectively, Topic 842) on January 1, 2019, we determine whether the arrangement is or contains a lease at the inception of the arrangement and if such a lease is classified as a financing lease or operating lease at lease commencement. All of our leases are classified as operating leases. Leases with a term greater than one year are included in operating lease right-of-use assets (ROU asset), current portion of lease liabilities, and lease liabilities, net of current portion in our condensed consolidated balance sheet at March 31, 2019. If a lease contains an option to renew, the renewal option is included in the calculation of lease liabilities if we are reasonably certain at lease commencement the renewal option will be exercised. Lease liabilities and their corresponding ROU assets are measured at the present value of the remaining lease payments, discounted at an appropriate incremental borrowing rate at lease commencement, or as of January 1, 2019, for our existing leases. Management uses judgment to estimate 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. Certain adjustments to the ROU asset may be required for items such as initial direct lease costs, lease incentives, scheduled rent escalations and impairment charges if we determine the ROU asset is impaired. Operating lease expense is recognized on a straight-line basis over the lease term. We elected the post-transition practical expedient to not separate lease components from non-lease components for all existing lease classes. We also elected a policy of not recording leases on our condensed balance sheets when a lease has a term of one year or less. In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. Additionally, the amendments expanded the disclosure requirements on the analysis of stockholders’ equity for interim financial statements. Under the amendments, a summary of changes in each caption of stockholders’ equity presented in the consolidated balance sheets must be provided in a note or separate statement. The final rule regarding stockholders’ equity was effective in the fourth quarter of 2018. The SEC provided relief on the effective date until the first quarter of 2019, and we have provided this disclosure beginning with this Quarterly Form 10-Q. Recent Accounting Pronouncements Not Yet Effective ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments requires that certain financial assets be measured at amortized cost net of an allowance for estimated credit losses such that the net receivable represents the present value of expected cash collection. In addition, this standard update requires that certain financial assets be measured at amortized cost reflecting an allowance for estimated credit losses expected to occur over the life of the assets. The estimate of credit losses must be based on all relevant information including historical information, current conditions and reasonable and supportable forecasts that affect the collectability of the amounts. This standard update is effective for us on January 1, 2020 with early adoption permitted. We expect to adopt this ASU on January 1, 2020 and are currently evaluating the effect that the updated standard will have on our consolidated financial statements and related disclosures. ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the amendments in ASU 2017-04, an entity should recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The updated guidance requires a prospective adoption. ASU 2017-04 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating the timing and effect that the updated standard will have on our consolidated financial statements and related disclosures. ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement modifies the disclosure requirements in Topic 820, Fair Value Measurement, by removing certain disclosure requirements related to the fair value hierarchy, modifying existing disclosure requirements related to measurement uncertainty and adding new disclosure requirements, such as disclosing the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and disclosing the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. This ASU is effective for public companies for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year. Early adoption is permitted for any removed or modified disclosures. We are currently |

Disaggregation of Revenue [Abstract] | |
Collaborative Arrangement | Collaborative Arrangement In March 2019, we entered into an agreement (Shinyaku Agreement) with Nippon Shinyaku Co., Ltd. (Shinyaku) for the exclusive distribution of Fintepla for the treatment of Dravet syndrome and LGS. As part of the Shinyaku Agreement, we are responsible for completing the global clinical development and all regulatory approval activities for Fintepla to support the submission of new drug applications in Japan for Dravet syndrome and LGS. Shinyaku will be responsible for the commercialization activities including the promotion, marketing, sale and distribution of Fintepla in Japan. Upon regulatory approval of Fintepla in Japan, Shinyaku will also act as our exclusive distributor for commercial shipment and distribution of Fintepla in Japan. If we pursue a global development of Fintepla for indications other than Dravet syndrome or LGS, Shinyaku has the option to participate in the development for such indications in Japan, subject to cost sharing requirements pursuant to the agreement. Activities under the Shinyaku Agreement will be governed by a joint steering committee (JSC) consisting of three representatives from each party to the agreement. All decisions of the JSC are to be made by a unanimous vote with tie-breaking rights provided to each party for certain matters related to development, regulatory approval and commercialization. Shinyaku has agreed to support development and regulatory approval of Fintepla in Japan and obtain distribution exclusivity through the payment of $20.0 million, of which $15.5 million was due shortly after the execution of the agreement with the remainder payable over the next two years. We and Shinyaku have agreed to proportionally share the Japan specific development costs that may arise outside of the initial development plan and any post-approval clinical study costs in Japan. In addition, we can earn up to $66.0 million from Shinyaku for the achievement of certain regulatory milestones related to the treatment of Dravet syndrome and the treatment of LGS. After regulatory approval of Fintepla in Japan has been obtained, we have agreed to supply Shinyaku with Fintepla upon receipt of purchase orders at our actual manufacturing cost plus a fixed transfer price mark-up, a fixed percentage of Shinyaku's net sales of Fintepla in Japan for such fiscal year, and a net price mark-up based on a percent of the applicable aggregate sales of Fintepla by Shinyaku for such fiscal year. The net price mark-up percentage increases with Shinyaku’s sales of Fintepla annual net sales in Japan and ranges between mid-twenties and is capped at a low thirties of the aggregate annual net sales for an applicable fiscal year. In addition, we can earn up to an additional $42.5 million tied to the achievement of certain net sales milestones by Shinyaku through the term of the agreement. The Shinyaku Agreement expires in September of 2045, unless earlier terminated by either party for a change in control, a material breach, bankruptcy, dissolution, or winding up of such other party. The Shinyaku Agreement may be also terminated by either party: (1) with one year prior written notice to the other party on or after the date of the first commercial sale of a competing generic version of the Fintepla in Japan, (2) if, prior to the launch of the Fintepla in Japan, a party has a good faith concern, based on credible evidence, that such launch is not likely to be possible with commercially reasonable efforts, or (3) if a party believes Fintepla poses a substantial safety concern. We may also terminate the agreement following the second anniversary of the first commercial sale of the Fintepla in Japan if Shinyaku has failed to achieve or maintain certain diligence obligations under the Shinyaku Agreement. Shinyaku may also terminate the agreement if, prior to the launch of the Fintepla in Japan, Shinyaku has a good faith concern that Fintepla will not be commercially viable in the Japan. As of March 31, 2019, no performance for any of the units of account under this agreement had occurred. Of the $20.0 million, we have recorded our unconditional right to receive $15.5 million in advance of performance in accounts receivable with a corresponding amount in deferred revenue in the condensed consolidated balance sheet and the remaining $4.5 million will be billed in accordance with the terms of the agreement. We have classified $5.0 million of the deferred revenue as current. The remaining consideration related to this agreement was fully constrained at March 31, 2019. |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A three-level valuation hierarchy has been established under GAAP for disclosure of fair value measurements. The valuation hierarchy is based on the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows: Level 1: Observable inputs such as quoted prices in active markets; Level 2: Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Our financial instruments consist primarily of cash and cash equivalents, marketable securities, accounts receivable, other current assets, accounts payable and accrued liabilities, contingent consideration liabilities and our outstanding common stock warrant liabilities. Certain cash equivalents, marketable securities, contingent consideration liabilities and common stock warrant liabilities are reported at their respective fair values on our condensed consolidated balance sheets. The remaining financial instruments are carried at cost which approximates their respective fair values because of the short-term nature of these financial instruments. The following tables summarize assets and liabilities recognized or disclosed at fair value on a recurring basis as of March 31, 2019 and December 31, 2018 (in thousands): Level 1 Level 2 Level 3 Total March 31, 2019 Assets: Cash equivalents: Commercial paper $ — $ 15,945 $ — $ 15,945 Money market funds 21,005 — — 21,005 U.S. Treasury securities — 9,985 — 9,985 Marketable securities: Commercial paper — 176,705 — 176,705 Corporate debt securities — 84,116 — 84,116 Certificate of deposits — 48,744 — 48,744 U.S. Treasury securities — 112,842 — 112,842 Total assets (1) $ 21,005 $ 448,337 $ — $ 469,342 Liabilities: Common stock warrant liabilities (2) $ — $ — $ 646 $ 646 Contingent consideration liabilities (3) — — 71,200 71,200 Total liabilities $ — $ — $ 71,846 $ 71,846 Level 1 Level 2 Level 3 Total December 31, 2018 Assets: Cash equivalents: Money market funds $ 63,232 $ — $ — $ 63,232 Marketable securities: Commercial paper — 152,940 — 152,940 Corporate debt securities — 60,605 — 60,605 Certificate of deposits — 128,647 — 128,647 U.S. Treasury securities — 103,541 — 103,541 Total assets (1) $ 63,232 $ 445,733 $ — $ 508,965 Liabilities: Common stock warrant liabilities (2) $ — $ — $ 343 $ 343 Contingent consideration liabilities (3) — — 78,200 78,200 Total liabilities $ — $ — $ 78,543 $ 78,543 (1) Fair value is determined by taking into consideration valuations obtained from third-party pricing services. The third-party pricing services utilize industry standard valuation models, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker/dealer quotes on the same or similar securities; issuer credit spreads; benchmark securities; and other observable inputs. (2) Represents the fair value of common stock warrants outstanding that may require cash settlement under certain circumstances. We estimated the fair value of the warrant liabilities using the Black-Scholes valuation model. As of December 31, 2018 and March 31, 2019, common stock warrant liabilities relate to warrants issued in July 2011 in connection with a debt financing arrangement. The warrants entitle the holder to purchase up to 28,125 shares of our common stock at an exercise price of $72.00 per share and expires in July 2021. (3) In connection with a prior acquisition in 2014, we may be required to pay future contingent consideration upon the achievement of specified development, regulatory approval or sales-based milestone events. We estimated the fair value of the contingent consideration liabilities on the acquisition date using a probability-weighted income approach, which reflects the probability and timing of future payments. This fair value measurement is based on significant Level 3 inputs such as the anticipated timelines and probability of achieving development, regulatory approval or sales-based milestone events and projected revenues. The resulting probability-weighted cash flows are discounted at risk-adjusted interest rates. Subsequent to the acquisition date, at each reporting period prior to settlement, we revalue these liabilities by performing a review of the assumptions listed above and record increases or decreases in the fair value of these contingent consideration liabilities. In the absence of any significant changes in key assumptions, the quarterly determination of fair values of these contingent consideration liabilities would primarily reflect the passage of time and risk-adjusted interest rates. Significant judgment is used in determining Level 3 inputs and fair value measurements as of the acquisition date and for each subsequent reporting period. Updates to assumptions could have a significant impact on our results of operations in any given period and actual results may differ from estimates. For example, significant increases in the probability of achieving a milestone or projected revenues would result in a significantly higher fair value measurement while significant decreases in the estimated probability of achieving a milestone or projected revenues would result in a significantly lower fair value measurement. Significant increases in the discount rate or in the anticipated timelines would result in a significantly lower fair value measurement while significant decreases in the discount rate or anticipated timelines would result in a significantly higher fair value measurement. The acquisition provides for aggregate contingent consideration of up to $95.0 million, of which $10.0 million was paid in March 2019. As of March 31, 2019, the estimated fair value of our contingent consideration liabilities was $71.2 million, of which $22.8 million has been classified as current liabilities. The classification was based upon our reasonable expectation as to the timing of settlement of certain specified milestones. The following table provides a reconciliation of liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three months ended March 31, 2019 and 2018 (in thousands): December 31, 2018 Change in Fair Value Settlements March 31, 2019 Contingent consideration liabilities $ 78,200 $ 3,000 $ (10,000) $ 71,200 Common stock warrant liabilities 343 303 — 646 December 31, 2017 Change in Fair Value Settlements March 31, 2018 Contingent consideration liabilities $ 76,900 $ — $ — $ 76,900 Common stock warrant liabilities 512 (17) — 495 The changes in fair value of the liabilities shown in the table above are recorded through change in fair value of contingent consideration liabilities within operating expense and the change in fair value of common stock warrant liabilities within other income (expense) in the condensed consolidated statements of operations. There were no transfers between levels during the periods presented. See Note 4 for further information regarding the amortized cost of our financial instruments. |

Leases | Leases We have two noncancellable operating leases consisting of administrative and research and development office space for our Emeryville, California headquarters and former headquarters in San Diego, California that expire in May 2027 and March 2020, respectively. Our Emeryville lease includes a renewal option for an additional five years, which were not included in our determination of the lease term under the legacy lease standard as renewal was not reasonably assured at the inception of the lease. As a result, we have not considered the optional period in determining our ROU assets and lease liabilities. Our former headquarters has been subleased to an unrelated third party for the remainder of our original lease term. As of March 31, 2019, we do not have any material finance leases or service contracts with lease arrangements. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. The components of lease costs, which were included in our condensed consolidated statements of operations, were as follows (in thousands): Three Months Ended Lease costs Operating lease cost $ 499 Short-term lease cost (1) 328 Sublease income (145) Total $ 682 ( 1) Short-term lease cost included $0.2 million related to a short-term lease that expired in March 2019.

Stock-Based Compensation | Stock-Based CompensationWe have issued stock-based awards from various equity incentive and stock purchase plans, as more fully described in the consolidated financial statements and related notes included in our 2018 Annual Report on Form 10-K. Under our 2010 Equity Incentive Award Plan, which was amended in June 2012 (2010 Plan), the aggregate number of shares of our common stock that may be issued as stock-based awards may not exceed 7,500,000 shares. At December 31, 2018, 1,550,351 shares were available for grant under the 2010 Plan. Pursuant to its evergreen provision, the number of shares reserved for issuance under the 2010 Plan automatically increases on January 1 of each year, commencing on January 1, 2013, and on each January 1 through and including January 1, 2020, in an amount equal to 4% of the total number of shares of common stock outstanding on December 31 of the preceding year, or a lesser number of shares as determined by our board of directors. On January 1, 2019, the increase in shares reserved for issuance pursuant to the evergreen provision was limited to 589,619 shares as the 2010 Plan’s maximum 7,500,000 shares reserved for issuance was reached. As of March 31, 2019, 1,298,107 shares were available for grant under the 2010 Plan. In 2013, our board of directors adopted the Inducement Plan, which allows us to grant equity awards only to new employees as an inducement material to join us. Effective March 27, 2019, our board of directors approved an increase to the share reserve under the Inducement Plan by 100,000 shares resulting in the aggregate number of shares of our common stock that may be issued as stock-based awards to 737,500 shares. As of March 31, 2019, there were 124,925 shares available for grant under the Inducement Plan.

Net Loss per Share | Net Loss Per Share Basic net loss from continuing operations per share is calculated by dividing net loss from continuing operations by the weighted average number of shares outstanding for the period. Diluted net loss from continuing operations per share is calculated by dividing net loss from continuing operations by the weighted average number of shares of common stock and potential dilutive common stock equivalents outstanding during the period if the effect is dilutive. The Company’s potentially dilutive shares of common stock include outstanding stock options, restricted stock units and warrants to purchase common stock.

United Kingdom (U.K.) Research and Development Incentives | United Kingdom (U.K.) Research and Development Incentives We carry out extensive research and development activities that benefit from the U.K.’s small and medium-sized enterprise (SME) research and development tax credit regime, whereby we may either receive an enhanced U.K. tax deduction on our eligible research and development activities or, when an SME entity is in a net operating loss position, elect to surrender net operating losses that arise from its eligible research and development activities in exchange for a cash payment from the U.K. tax authorities. These refundable cash credits, which may be received without regard to actual tax liability, are not subject to accounting for income taxes and have been recorded as a component of other income. In December 2018, we filed a claim as an SME for a $7.1 million refundable cash credit for its 2016 tax year, which was received in February 2019.We recorded this amount as a component of other income for the year-ended December 31, 2018. As of the date hereof, we have not filed claims for any refundable cash credit for its 2017 or 2018 tax years, nor has it recorded any balances related to claims for these years or for the 2019 tax year, as collectability is deemed not probable or reasonably assured. |

Accounting Policies [Abstract] | |
Use of Estimates | Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results may differ from those estimates. |
Revenue Recognition | Revenue Recognition We analyze our collaboration agreements to assess whether such arrangements, or transactions between arrangement participants, involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities or are more akin to a vendor-customer relationship. In making this evaluation, we consider whether the activities of the collaboration are considered to be distinct and deemed to be within the scope of the collaboration guidance and those that are more reflective of a vendor-customer relationship and, therefore, within the scope of the revenue with contracts with customer guidance. This assessment is performed throughout the life of the arrangement based on changes in the responsibilities of all parties in the arrangement. For elements of collaboration arrangements that are not accounted for pursuant to the revenue from contracts with customer guidance, an appropriate recognition method is determined and applied consistently, generally by analogy to the revenue from contracts with customers guidance. Revenue from transactions with collaboration participants is presented apart from revenue with contracts with customers in our condensed consolidated statement of operations. Amounts received prior to satisfying the revenue recognition criteria are recorded as deferred revenue in the condensed consolidated balance sheets. If the related performance obligation is expected to be satisfied within the next twelve months this will be classified in current liabilities. Unconditional rights to receive consideration in advance of performance are recorded as receivables and deferred revenue in the condensed consolidated balance sheets when we have a contractual right to bill and receive the payment, performance is expected to commence shortly and there is less than a year between billing and performance. Amounts recognized for satisfied performance obligations prior to the right to payment becoming unconditional are recorded as contract assets in the condensed consolidated balance sheets. If we expect to have an unconditional right to receive consideration in the next twelve months, this will be classified in current assets. A net contract asset or liability is presented for each contract with a customer. For arrangements or transactions between arrangement participants determined to be within the scope of the contracts with customers guidance, we perform the following steps to determine the appropriate amount of revenue to be recognized as we fulfill our obligations: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated selling prices; and (v) recognition of revenue when (or as) we satisfy each performance obligation. At contract inception, we assess the goods or services promised in a contract with a customer and identifies those distinct goods and services that represent a performance obligation. A promised good or service may not be identified as a performance obligation if it is immaterial in the context of the contract with the customer, if it is not separately identifiable from other promises in the contract (either because it is not capable of being separated or because it is not separable in the context of the contract), or if the performance obligation does not provide the customer with a material right. We consider the terms of the contract and our customary business practices to determine the transaction price. The transaction price is the amount of consideration to which we expect to be entitled in exchange for transferring promised goods or services to a customer. The consideration promised in a contract with a customer may include fixed amounts, variable amounts, or both. Variable consideration will only be included in the transaction price when it is not considered constrained, which is when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. If it is determined that multiple performance obligations exist, the transaction price is allocated at the inception of the agreement to all identified performance obligations based on the relative stand-alone selling prices. The relative selling price for each deliverable is estimated using objective evidence if it is available. If objective evidence is not available, we use our best estimate of the selling price for the deliverable. Revenue is recognized when, or as, we satisfy a performance obligation by transferring a promised good or service to a customer. An asset is transferred when, or as, the customer obtains control of that asset, which for a service, is considered to be as the services are received and used. We recognize revenue over time by measuring the progress toward complete satisfaction of the relevant performance obligation using an appropriate input or output method based on the nature of the good or service promised to the customer. After contract inception, the transaction price is reassessed at every period end and updated for changes such as resolution of uncertain events. Any change in the transaction price is allocated to the performance obligations on the same basis as at contract inception. Management may be required to exercise considerable judgment in estimating revenue to be recognized. Judgment is required in identifying performance obligations, estimating the transaction price, estimating the stand-alone selling prices of identified performance obligations, which may include forecasted revenue, development timelines, reimbursement rates for personnel costs, discount rates and probabilities of technical and regulatory success, and estimating the progress towards satisfaction of performance obligations. |
Collaborative Arrangements | ASU 2018-18, Collaboration Arrangements: Clarifying the Interaction between Topic 808 and Topic 606 makes targeted improvements for collaborative arrangements by (1) clarifying that certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606 when the collaboration arrangement participant is a customer, (2) adding unit of account guidance to assess whether the collaboration arrangement or a part of the arrangement is with a customer and (3) precluding a company from presenting transactions with collaboration arrangement participants that are not directly related to sales to third parties together with revenue from contracts with customers. On January 1, 2019, we early adopted this new standard and its applicability has been considered in the accounting for our collaborative arrangement with Nippon Shinyaku Co., Ltd. (See Note 3). |
Leases | Leases In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Topic 842 establishes a right-of-use asset model that requires all lessees to recognize ROU assets and liabilities for leases with a duration greater than one year on the balance sheet as well as provide disclosures with respect to certain qualitative and quantitative information regarding the amount, timing and uncertainty of cash flows arising from leases. On January 1, 2019, we adopted Topic 842 using the modified retrospective approach and elected the package of practical expedients permitted under transition guidance. Consequently, prior period financial information and related disclosures have not been adjusted and will continue to be presented in accordance with the previous lease standard. In addition, we elected the package of transition provisions available for existing contracts, which allowed us to carryforward our historical assessments of (1) whether contracts are or contain leases, (2) lease classification and (3) initial direct lease costs for existing leases. We did not elect the practical expedient allowing the use-of-hindsight which would require us to reassess the lease term of our leases based on all facts and circumstances through the effective date and did not elect the practical expedient pertaining to land easements as this is not applicable to the current contract portfolio. The adoption of Topic 842 did not have a material impact on our condensed consolidated statements of operations and cash flows. The impact on the accompanying condensed consolidated balance sheet as of January 1, 2019 was as follows (in thousands): December 31, 2018 Adjustments Due to the January 1, 2019 Assets Operating lease right-of-use assets $ — $ 8,641 $ 8,641 Liabilities Other accrued liabilities 1,845 (363) $ 1,482 Current portion of operating lease liabilities — 1,058 1,058 Operating lease liabilities, net of current portion — 11,776 11,776 Other long-term liabilities 3,830 (3,830) — Total 5,675 8,641 14,316 Upon adoption on January 1, 2019, we recorded operating lease ROU assets and lease liabilities of $8.6 million and $12.8 million, respectively, with the difference between ROU assets and lease liabilities attributed to the reclassifications of deferred rent and lease incentive obligations, a cease-use liability and initial direct leasing costs as a component of ROU assets. Prior to January 1, 2019, we recognized related rent expense on a straight-line basis over the term of the lease. Incentives granted under our operating lease, including allowances for leasehold improvements and rent holidays, were recognized as reductions to rent expense on a straight-line basis over the term of the lease. Deferred rent consisted of the difference between rent expense recognized on a straight-line basis and cash rent payments. Subsequent to the adoption of Accounting Standards Update (ASU) 2016-02 and related amendments (collectively, Topic 842) on January 1, 2019, we determine whether the arrangement is or contains a lease at the inception of the arrangement and if such a lease is classified as a financing lease or operating lease at lease commencement. All of our leases are classified as operating leases. Leases with a term greater than one year are included in operating lease right-of-use assets (ROU asset), current portion of lease liabilities, and lease liabilities, net of current portion in our condensed consolidated balance sheet at March 31, 2019. If a lease contains an option to renew, the renewal option is included in the calculation of lease liabilities if we are reasonably certain at lease commencement the renewal option will be exercised. Lease liabilities and their corresponding ROU assets are measured at the present value of the remaining lease payments, discounted at an appropriate incremental borrowing rate at lease commencement, or as of January 1, 2019, for our existing leases. Management uses judgment to estimate 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. Certain adjustments to the ROU asset may be required for items such as initial direct lease costs, lease incentives, scheduled rent escalations and impairment charges if we determine the ROU asset is impaired. Operating lease expense is recognized on a straight-line basis over the lease term. We elected the post-transition practical expedient to not separate lease components from non-lease components for all existing lease classes. We also elected a policy of not recording leases on our condensed balance sheets when a lease has a term of one year or less. In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. Additionally, the amendments expanded the disclosure requirements on the analysis of stockholders’ equity for interim financial statements.

Recent Accounting Pronouncements | Recently Adopted Accounting Pronouncements ASU 2018-18, Collaboration Arrangements: Clarifying the Interaction between Topic 808 and Topic 606 makes targeted improvements for collaborative arrangements by (1) clarifying that certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606 when the collaboration arrangement participant is a customer, (2) adding unit of account guidance to assess whether the collaboration arrangement or a part of the arrangement is with a customer and (3) precluding a company from presenting transactions with collaboration arrangement participants that are not directly related to sales to third parties together with revenue from contracts with customers. On January 1, 2019, we early adopted this new standard and its applicability has been considered in the accounting for our collaborative arrangement with Nippon Shinyaku Co., Ltd. (See Note 3). Leases In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Topic 842 establishes a right-of-use asset model that requires all lessees to recognize ROU assets and liabilities for leases with a duration greater than one year on the balance sheet as well as provide disclosures with respect to certain qualitative and quantitative information regarding the amount, timing and uncertainty of cash flows arising from leases. On January 1, 2019, we adopted Topic 842 using the modified retrospective approach and elected the package of practical expedients permitted under transition guidance. Consequently, prior period financial information and related disclosures have not been adjusted and will continue to be presented in accordance with the previous lease standard. In addition, we elected the package of transition provisions available for existing contracts, which allowed us to carryforward our historical assessments of (1) whether contracts are or contain leases, (2) lease classification and (3) initial direct lease costs for existing leases. We did not elect the practical expedient allowing the use-of-hindsight which would require us to reassess the lease term of our leases based on all facts and circumstances through the effective date and did not elect the practical expedient pertaining to land easements as this is not applicable to the current contract portfolio. The adoption of Topic 842 did not have a material impact on our condensed consolidated statements of operations and cash flows. The impact on the accompanying condensed consolidated balance sheet as of January 1, 2019 was as follows (in thousands): December 31, 2018 Adjustments Due to the January 1, 2019 Assets Operating lease right-of-use assets $ — $ 8,641 $ 8,641 Liabilities Other accrued liabilities 1,845 (363) $ 1,482 Current portion of operating lease liabilities — 1,058 1,058 Operating lease liabilities, net of current portion — 11,776 11,776 Other long-term liabilities 3,830 (3,830) — Total 5,675 8,641 14,316 Upon adoption on January 1, 2019, we recorded operating lease ROU assets and lease liabilities of $8.6 million and $12.8 million, respectively, with the difference between ROU assets and lease liabilities attributed to the reclassifications of deferred rent and lease incentive obligations, a cease-use liability and initial direct leasing costs as a component of ROU assets. Prior to January 1, 2019, we recognized related rent expense on a straight-line basis over the term of the lease. Incentives granted under our operating lease, including allowances for leasehold improvements and rent holidays, were recognized as reductions to rent expense on a straight-line basis over the term of the lease. Deferred rent consisted of the difference between rent expense recognized on a straight-line basis and cash rent payments. Subsequent to the adoption of Accounting Standards Update (ASU) 2016-02 and related amendments (collectively, Topic 842) on January 1, 2019, we determine whether the arrangement is or contains a lease at the inception of the arrangement and if such a lease is classified as a financing lease or operating lease at lease commencement. All of our leases are classified as operating leases. Leases with a term greater than one year are included in operating lease right-of-use assets (ROU asset), current portion of lease liabilities, and lease liabilities, net of current portion in our condensed consolidated balance sheet at March 31, 2019. If a lease contains an option to renew, the renewal option is included in the calculation of lease liabilities if we are reasonably certain at lease commencement the renewal option will be exercised. Lease liabilities and their corresponding ROU assets are measured at the present value of the remaining lease payments, discounted at an appropriate incremental borrowing rate at lease commencement, or as of January 1, 2019, for our existing leases. Management uses judgment to estimate 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. Certain adjustments to the ROU asset may be required for items such as initial direct lease costs, lease incentives, scheduled rent escalations and impairment charges if we determine the ROU asset is impaired. Operating lease expense is recognized on a straight-line basis over the lease term. We elected the post-transition practical expedient to not separate lease components from non-lease components for all existing lease classes. We also elected a policy of not recording leases on our condensed balance sheets when a lease has a term of one year or less. In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. Additionally, the amendments expanded the disclosure requirements on the analysis of stockholders’ equity for interim financial statements. Under the amendments, a summary of changes in each caption of stockholders’ equity presented in the consolidated balance sheets must be provided in a note or separate statement. The final rule regarding stockholders’ equity was effective in the fourth quarter of 2018. The SEC provided relief on the effective date until the first quarter of 2019, and we have provided this disclosure beginning with this Quarterly Form 10-Q. Recent Accounting Pronouncements Not Yet Effective ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments requires that certain financial assets be measured at amortized cost net of an allowance for estimated credit losses such that the net receivable represents the present value of expected cash collection. In addition, this standard update requires that certain financial assets be measured at amortized cost reflecting an allowance for estimated credit losses expected to occur over the life of the assets. The estimate of credit losses must be based on all relevant information including historical information, current conditions and reasonable and supportable forecasts that affect the collectability of the amounts. This standard update is effective for us on January 1, 2020 with early adoption permitted. We expect to adopt this ASU on January 1, 2020 and are currently evaluating the effect that the updated standard will have on our consolidated financial statements and related disclosures. ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the amendments in ASU 2017-04, an entity should recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The updated guidance requires a prospective adoption. ASU 2017-04 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating the timing and effect that the updated standard will have on our consolidated financial statements and related disclosures. ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement modifies the disclosure requirements in Topic 820, Fair Value Measurement, by removing certain disclosure requirements related to the fair value hierarchy, modifying existing disclosure requirements related to measurement uncertainty and adding new disclosure requirements, such as disclosing the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and disclosing the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. This ASU is effective for public companies for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year. Early adoption is permitted for any removed or modified disclosures. We are currently |
Fair Value Measurements | Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A three-level valuation hierarchy has been established under GAAP for disclosure of fair value measurements. The valuation hierarchy is based on the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows: Level 1: Observable inputs such as quoted prices in active markets; Level 2: Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. |
Stock-based Compensation | We have issued stock-based awards from various equity incentive and stock purchase plans, as more fully described in the consolidated financial statements and related notes included in our 2018 Annual Report on Form 10-K. Under our 2010 Equity Incentive Award Plan, which was amended in June 2012 (2010 Plan), the aggregate number of shares of our common stock that may be issued as stock-based awards may not exceed 7,500,000 shares. At December 31, 2018, 1,550,351 shares were available for grant under the 2010 Plan. Pursuant to its evergreen provision, the number of shares reserved for issuance under the 2010 Plan automatically increases on January 1 of each year, commencing on January 1, 2013, and on each January 1 through and including January 1, 2020, in an amount equal to 4% of the total number of shares of common stock outstanding on December 31 of the preceding year, or a lesser number of shares as determined by our board of directors. On January 1, 2019, the increase in shares reserved for issuance pursuant to the evergreen provision was limited to 589,619 shares as the 2010 Plan’s maximum 7,500,000 shares reserved for issuance was reached. As of March 31, 2019, 1,298,107 shares were available for grant under the 2010 Plan. In 2013, our board of directors adopted the Inducement Plan, which allows us to grant equity awards only to new employees as an inducement material to join us. Effective March 27, 2019, our board of directors approved an increase to the share reserve under the Inducement Plan by 100,000 shares resulting in the aggregate number of shares of our common stock that may be issued as stock-based awards to 737,500 shares. As of March 31, 2019, there were 124,925 shares available for grant under the Inducement Plan. |
Net Loss per Share | Basic net loss from continuing operations per share is calculated by dividing net loss from continuing operations by the weighted average number of shares outstanding for the period. Diluted net loss from continuing operations per share is calculated by dividing net loss from continuing operations by the weighted average number of shares of common stock and potential dilutive common stock equivalents outstanding during the period if the effect is dilutive. |
