Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Description of Business and Basis of Presentation | 1. Description of Business and Basis of Presentation Organization NantKwest, Inc. (the Company) was incorporated in Illinois on October 7, 2002 under the name ZelleRx Corporation. On January 22, 2010, the Company changed its name to Conkwest, Inc., and on July 10, 2015, the Company changed its name to NantKwest, Inc. In March 2014, the Company redomesticated from the State of Illinois to the State of Delaware and the Illinois Company ceased to exist. The Company is a pioneering clinical-stage immunotherapy biotechnology company headquartered in San Diego, California with certain operations in Culver City and El Segundo, California and Woburn, Massachusetts. The Company is focused on harnessing the power of the innate immune system by using the natural killer cell to treat cancer, infectious diseases and inflammatory diseases. A critical aspect of the Company’s strategy is to invest significantly in expanding the aNK platform and the development of the Company’s product candidates. The Company holds the exclusive right to commercialize activated natural killer (aNK) cells, a commercially viable natural killer cell-line, and a variety of genetically modified derivatives capable of killing cancer and virally infected cells. The Company owns corresponding U.S. and foreign composition and methods-of-use patents and applications covering the clinical use of aNK cells as a therapeutic to treat a spectrum of clinical conditions. The Company also licensed exclusive commercial rights to a portfolio of CD16 bearing aNK cells along with the corresponding U.S. and foreign composition and methods-of-use patents and applications covering the non-clinical use in laboratory testing of monoclonal antibodies, as well as clinical use as a therapeutic to treat cancers in combination with antibody products. The Company has licensed or sub-licensed its CD16 bearing aNK cell lines and intellectual property to numerous pharmaceutical and biotechnology companies for such non-clinical uses. The Company also licensed exclusive commercial rights to a unique HER2-specific receptor bearing aNK cell line along with the corresponding U.S. and foreign composition and methods-of-use patents and applications covering clinical use as a therapeutic to treat cancers. The Company retains exclusive worldwide rights to clinical and research data, intellectual property and know-how developed with the Company’s aNK cells, as well as the only clinical grade master cell bank. Unaudited Interim The accompanying condensed consolidated balance sheet at March 31, 2018, the condensed consolidated statements of operations and comprehensive loss for the three months ended March 31, 2018 and 2017, the condensed consolidated statements of cash flows for the three months ended March 31, 2018 and 2017, and the condensed consolidated statement of stockholders’ equity for the three months ended March 31, 2018 have been prepared by management of the Company and have not been audited. These financial statements have been prepared on the same basis as the audited consolidated financial statements for the fiscal year ended December 31, 2017 and, in the opinion of management, include all normal recurring adjustments necessary for a fair statement of the Company’s results for the periods presented. These financial statements should be read in conjunction with the financial statements and notes thereto for the fiscal year ended December 31, 2017 included in the Company’s Annual Report on Form 10-K. Interim operating results are not necessarily indicative of operating results for the full year. The year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America (GAAP). Liquidity As of March 31, 2018, the Company had an accumulated deficit of approximately $526.0 million. The Company also had negative cash flow from operations of approximately $15.5 million during the three months ended March 31, 2018. The Company expects that it will likely need additional capital to further fund development of, and seek regulatory approvals for, its product candidates, and begin to commercialize any approved products. The Company is currently focused primarily on the development of immunotherapeutic treatments for cancers and debilitating viral infections using targeted cancer killing cell lines, and believes such activities will result in the Company’s continued incurrence of significant research and development and other expenses related to those programs. If the clinical trials for any of the Company’s product candidates fail or produce unsuccessful results and those product candidates do not gain regulatory approval, or if any of the Company’s product candidates, if approved, fail to achieve market acceptance, the Company may never become profitable. Even if the Company achieves profitability in the future, it may not be able to sustain profitability in subsequent periods. The Company intends to cover its future operating expenses through cash and cash equivalents and marketable debt securities on hand and through a combination of equity offerings, debt financings, government or other third-party funding, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements. Additional financing may not be available to the Company when needed and, if available, financing may not be obtained on terms favorable to the Company or its stockholders. While the Company expects its existing cash and cash equivalents and marketable debt securities will enable it to fund operations and capital expenditure requirements for at least the next twelve months, it may not have sufficient funds to reach commercialization. Failure to obtain adequate financing when needed may require the Company to delay, reduce, limit or terminate some or all of its development programs or future commercialization efforts or grant rights to develop and market product candidates that the Company might otherwise prefer to develop and market itself which could adversely affect the Company’s ability to operate as a going concern. If the Company raises additional funds from the issuance of equity securities, substantial dilution to existing stockholders may result. If the Company raises additional funds by incurring debt financing, the terms of the debt may involve significant cash payment obligations as well as covenants and specific financial ratios that may restrict the Company’s ability to operate its business. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies There have been no material changes in the Company’s significant accounting policies other than the adoption of accounting pronouncements below, as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. Principles of Consolidation and Equity Investments The Company’s condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Inex Bio, Inc. and 557 Doug St, LLC, and have been prepared in accordance with GAAP. All intercompany amounts have been eliminated. The Company applies the variable interest model under Accounting Standards Codification (ASC) Topic 810, Consolidation For entities the Company holds as an equity investment and are not consolidated under the VIE Model, the Company considers whether its investment constitutes ownership of a majority of the voting interests in the entity and therefore should be considered for consolidation under the voting interest model. Unconsolidated equity investments in the common stock or in-substance common stock of an entity under which the Company is able to exercise significant influence, but not control, are accounted for using the equity method. The Company’s ability to exercise significant influence is generally indicated by ownership of 20 to 50 percent interest in the voting securities of the entity. All other unconsolidated equity investments on which the Company is not able to exercise significant influence will be subsequently measured at fair value with unrealized Use of Estimates The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to stock-based compensation, the valuation allowance for deferred tax assets, preclinical and clinical trial accruals, impairment assessments, and the valuation of build-to-suit lease assets. The Company bases its estimates on historical experience and on various other market-specific and relevant assumptions that it believes to be reasonable under the circumstances. Actual results could differ from those estimates. Basic and Diluted Net Loss per Share of Common Stock Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding for the period. Diluted loss per share is computed similarly to basic loss per share except that the denominator is increased to include the number of additional shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive. For all periods presented, potentially dilutive securities are excluded from the computation of fully diluted loss per share as their effect is anti-dilutive. The following table details those securities that have been excluded from the computation of potentially dilutive securities: As of March 31, 2018 2017 Outstanding options 5,693,250 5,693,250 Outstanding restricted stock units 874,164 1,060,381 Outstanding warrants 17,706,818 17,768,314 Total 24,274,232 24,521,945 Amounts in the table above reflect the common stock equivalents of the noted instruments. Recently Adopted Accounting Policies Financial Assets and Liabilities and Equity Investment Effective January 1, 2018, the Company adopted Accounting Standard Update (ASU) 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities The Company owns non-marketable equity securities that are accounted for as an equity investment at cost minus impairment and plus or minus changes resulting from observable price changes because the preferred stock held by the Company is not considered in-substance common stock and such preferred stock does not have a readily determinable fair value. All investments are reviewed on a regular basis for possible impairment. If an investment's fair value is determined to be less than its net carrying value, the investment is written down to its fair value. Such an evaluation is judgmental and dependent on specific facts and circumstances. Factors considered in determining whether an impairment indicator is present include: the investees’ earning performance and clinical trial performance, change in the investees’ industry and geographic area in which it operates, offers to purchase or sell the security for a price less than the cost of the investment, issues that raise concerns about the investee's ability to continue as a going concern and any other information that the Company may be aware of related to the investment. Factors considered in determining whether an observable price change has occurred include: the price at which the investee issues equity instruments similar to those of the Company’s investment and the rights and preferences of those equity instruments compared to the Company’s. Revenue Recognition Beginning January 1, 2018, the Company follows the provisions of ASC Topic 606, Revenue from Contracts with Customers The Company derives substantially all of its revenue from non-exclusive license agreements with a limited number of pharmaceutical and biotechnology companies granting them the right to use the Company’s cell lines and intellectual property for non-clinical use. These agreements generally include upfront fees and annual research license fees for such use, as well as commercial license fees for sales of the Company’s licensee’s products developed or manufactured using the Company’s intellectual property and cell lines. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC Topic 606. A contract’s transaction price is allocated to each distinct performance obligation based on relative standalone selling price and recognized as revenue when, or as, the performance obligation is satisfied. Under the Company’s license agreements with customers, the Company typically promises to provide a license to use certain cell lines and related patents, the related know-how, and future research and development data that affects the license. The Company concluded that these promises represent one performance obligation due to the highly interrelated nature of the promises. The Company provides the cell lines and know-how immediately upon entering into the contracts. The research and development data is provided throughout the term of the contract when and if available. The Company’s license agreement with Intrexon included a nonrefundable upfront payment of $0.4 million, received when the Company entered into the contract in 2010. In this instance, the Company determined that under ASC 606 it would be appropriate to recognize the initial milestone payment at a point in time, when it transferred the license. In this case, the intellectual property provided under the contract is functional intellectual property under ASC 606 and was determined to be a distinct performance obligation in the context of the arrangement. Prior to adoption, the upfront payment had been initially recorded as deferred revenue and was being recognized into revenue on a straight-line basis. As a result, upon adoption of ASC 606, the Company adjusted its opening retained deficit for the effects of recognizing revenue upfront for the initial milestone. The adjustment to opening retained deficit upon adoption was not material. The license agreements may include nonrefundable upfront payments, event-based milestone payments, sales-based royalty payments, or some combination of these. The event-based milestone payments represent variable consideration and the Company uses the most likely amount method to estimate this variable consideration. Given the high degree of uncertainly around achievement of these milestones, the Company does not recognize revenue from these milestone payments until the uncertainty associated with these payments is resolved. The Company currently estimates variable consideration related to milestone payments to be zero and, as such, no revenue has been recognized for milestone payments. The Company will recognize revenue from sales-based royalty payments when or as the sales occur. On a quarterly basis, the Company will re-evaluate its estimate of milestone variable consideration to determine whether any amount should be included in the transaction price and recorded in revenue prospectively. Upon adoption, the Company changed its accounting policy from accounting for milestones payments under the milestone method to accounting for variable consideration as discussed above. The change in accounting policy did not change any amounts in the financial statements because of the significant uncertainty surrounding the estimate of variable consideration for milestone payments. The Company’s revenue from non-clinical license agreements is nominal. In the future, the Company may generate revenue from license agreements entered into for therapeutic uses. To date, the Company has not generated any revenue from product sales. If the Company fails to complete the development of its product candidates in a timely manner or fails to obtain regulatory approval for them, the Company may never be able to generate substantial future revenue. Statement of Cash Flows Effective January 1, 2018, the Company adopted ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments . ASU 2016-15 adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. Also, effective January 1, 2018, the Company adopted Statement of Cash Flows: Restricted Cash, a consensus of the FASB’s Emerging Issues Task Force . ASU 2016-18 requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Entities will also be required to reconcile such total to amounts on the balance sheet and disclose the nature of the restrictions. Both Updates will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual periods. Prior periods were retrospectively adjusted to conform to the current period’s presentation. There was no material impact on the Company’s statement of cash flows on adoption of either Update. Recent Accounting Pronouncements – Not Yet Adopted In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. Adoption of ASU 2018-02 is not expected to have a significant impact in the Company’s consolidated financial statements and disclosures. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. Adoption of ASU 2016-13 is not expected to have a significant impact in the Company’s consolidated financial statements and disclosures. In February 2016, the FASB issued ASU 2016-02, Leases |

Equity Investment | 4. Equity Investment In March 2017, the Company participated in a Series B convertible preferred stock financing and invested $8.5 million in Viracta Therapeutics, Inc. (Viracta), a clinical stage drug development company. The Company did not exercise the option to purchase up to an additional $8.5 million worth of shares of the Series B convertible preferred stock by the expiration date of September 30, 2017. In May 2017, the Company executed an exclusive worldwide license with Viracta to develop and commercialize Viracta’s proprietary histone deacetylase inhibitor drug candidate for use in combination with NK cell therapy and possibly additional therapies. Based on the level of equity investment at risk, Viracta is not a Variable Interest Entity (VIE) and therefore is not consolidated under the VIE Model. Also, the Company does not hold a controlling financial interest in Viracta and therefore is not consolidating Viracta under the voting interest model. As the preferred stock is not considered in-substance common stock, the investment is not within the scope of accounting for the investment under the equity method. As the preferred stock does not have a readily determinable fair value, the Company has elected to apply the practicability exception noted under ASC 825 and estimates the fair value at its $8.5 million cost minus impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. As of March 31, 2018, the Company’s qualitative impairment assessment did not indicate there were events or changes in circumstances that may have had a significant adverse effect on the fair value of the investment. The Company has not recorded any impairments as of March 31, 2018 or on a cumulative basis. Further, the Company has not identified any downward or upward adjustments due to observable price changes in the investment as of the March 31, 2018 or on a cumulative basis. The $8.5 million cost of the investment is recorded in equity investment on the condensed consolidated balance sheet as of March 31, 2018. |

The Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases. Therefore, the Company did not have any other-than-temporary impairment loss during the three months ended March 31, 2018. At March 31, 2018, 63 of the securities and bonds are in an unrealized loss position. The Company recorded realized gains and losses on sales or maturities of available-for-sale securities as follows (in thousands): Three Months Ended March 31, (unaudited) 2018 2017 Gross realized gains $ 2 $ 2 Gross realized losses — (5 ) Net realized gains $ 2 $ (3 ) |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | 6. Fair Value Measurements Fair value is defined as an exit price that would be received from the sale of an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Recurring Valuations In accordance with the authoritative guidance for financial assets and liabilities measured at fair value on a recurring basis (ASC Topic 820), the Company prioritizes the inputs used to measure fair value from market-based assumptions to entity specific assumptions as follows: • Level 1—Inputs based on quoted market prices for identical assets or liabilities in active markets at the measurement date. • Level 2—Observable inputs other than quoted prices in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3—Inputs which reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are unobservable in the market and significant to the instruments valuation. The following tables present the Company’s hierarchy for its assets measured at fair value on a recurring basis as of March 31, 2018 and December 31, 2017 (in thousands): Fair Value Measurements at March 31, 2018 (unaudited) Total Level 1 Level 2 Level 3 Assets: Current: Cash and cash equivalents $ 11,196 $ 11,196 $ — $ — Corporate debt securities 86,731 — 86,731 — Government sponsored securities 12,493 — 12,493 — Foreign government bonds 5,931 — 5,931 — Commercial paper 5,438 — 5,438 — Noncurrent: Corporate debt securities 12,394 — 12,394 — Government sponsored securities 2,697 — 2,697 — Total assets measured at fair value $ 136,880 $ 11,196 $ 125,684 $ — Fair Value Measurements at December 31, 2017 Total Level 1 Level 2 Level 3 Assets: Current: Cash and cash equivalents $ 23,872 $ 20,374 $ 3,498 $ — Corporate debt securities 82,109 — 82,109 — Government sponsored securities 19,233 — 19,233 — Foreign government bonds 2,938 — 2,938 — Noncurrent: Corporate debt securities 26,883 — 26,883 — Government sponsored securities 2,717 — 2,717 Total assets measured at fair value $ 157,752 $ 20,374 $ 137,378 $ — Non-recurring Valuation Non-financial assets and liabilities are recognized at fair value subsequent to initial recognition when they are deemed to be other-than-temporarily impaired.

Collaboration and License Agreements | 7. Collaboration and License Agreements Collaborative Arrangement A collaborative arrangement is a contractual arrangement that involves a joint operating activity. These arrangements involve two or more parties who are (i) active participants in the activity and (ii) exposed to significant risks and rewards dependent on the commercial success of the activity. There were no new collaborative agreements during the three months ended March 31, 2018 and 2017. License Agreement Chemotherapeutisches Forschungsinstitut Georg-Speyer-Haus (GSH) and DRK-Blutspendedienst Baden-Wurttenberg-Hessen gGmbH (BSD) License Agreement In August 2015, the Company entered into a license agreement with GSH and BSD under which the Company was granted an exclusive license to certain GSH-BSD patents, materials and know-how that specifically targets ErbB2 expressing cancers. In addition, GSH granted the Company an exclusive license to certain GSH only technology and materials. In consideration for the licenses, the Company agreed to pay initial and annual licensing fees, regulatory and commercial milestones and low single-digit percentage royalties on net sales of licensed products. The royalty term shall continue in a particular country until the later of (i) the expiration of the valid patent claims in such country or (ii) a specified period of time after the first commercial sale of licensed product in such country. The license agreement shall continue until no further payments are due at which time the licenses and rights will continue on a non-exclusive, royalty-free basis.

Commitments And Contingencies Disclosure [Abstract] | |
Commitments and contingencies | 8. Commitments and Contingencies Contingencies The Company records accruals for loss contingencies to the extent that the Company concludes it is probable that a liability has been incurred and the amount of the related loss can be reasonably estimated. The Company evaluates, on a quarterly basis, developments in legal proceedings and other matters that could cause a change in the potential amount of the liability recorded or of the range of potential losses disclosed. Additionally, the Company records receivables from third-party insurers when recovery has been determined to be probable. This includes instances when the Company’s third-party insurers have agreed to reimburse certain legal defense costs incurred with the applicable law firms by the Company. Appeal of USPTO Decision In March 2009, the Company received a final rejection in one of the Company’s original patent applications pertaining to certain limited methods of use claims for NK-92 from the U.S. Patent and Trademark Office (the USPTO), but the USPTO allowed claims on all of the other proposed claims, including other methods of use. The Company appealed this decision with the USPTO Board of Appeals and, in the fall of 2013, the Board of Appeals reversed the Examiner’s rejection of the claim to certain limited methods of use with NK-92, but affirmed the Examiner’s rejection of the remaining patent claims. In December 2013, the Company brought an action in the U.S. District Court for the Eastern District of Virginia to review the decision of the USPTO as the Company disagreed with the decision as to the certain limited non-allowed claims. On September 2, 2015, the U.S. District Court granted the USPTO’s motion for summary judgment. On September 24, 2015, the Company filed a notice of appeal to the United States Court of Appeals for the Federal Circuit. In September 2015, the USPTO filed a Motion for Expenses seeking $0.1 million for attorney’s fees and the USPTO’s expert witness fees. In February 2016, the U.S. District Court denied the USPTO’s Motion for Expenses for attorney’s fees and granted Director’s Motion for Expenses for the USPTO’s expert witness fees. The USPTO filed a notice of appeal on April 5, 2016. In May 2017, the Federal Circuit affirmed the U.S. District Court’s summary judgment ruling. The formal mandate was issued on June 26, 2017. In June 2017, the Federal Circuit reversed the U.S. District Court and remanded the case for the U.S. District Court to enter an award of $0.1 million in favor of the USPTO. On August 31, 2017, a majority of active Federal Circuit judges voted to vacate the June 2017 decision and hear the case en banc sua sponte. The USPTO filed its opening brief on November 15, 2017. The Company filed its opening brief on January 16, 2018. The USPTO filed its reply brief on January 31, 2018. Oral argument was heard on March 8, 2018. Based on the information available at present, the Company cannot reasonably estimate a range of loss for this action beyond the attorney and expert witness fees. Accordingly, the awarded fees have been accrued, but no liability associated with this action beyond the fees has been accrued. The Company is expensing legal costs associated with defending this litigation as the costs are incurred. Securities Litigation In March 2016, a putative securities class action complaint captioned Sudunagunta v. NantKwest, Inc., et al. The actions originally filed in state court were removed to federal court, and the various related actions have been consolidated. Plaintiffs assert causes of action for alleged Plaintiffs during various time periods from In September 2017, the court denied defendants' motion to dismiss the third amended consolidated complaint. On September 6, 2016, a putative Bushansky v. Soon-Shiong, et al. The Company is named solely as a nominal defendant. In October 2017, the first of two putative stockholder derivative complaints was filed in the Delaware Court of Chancery. The Delaware actions have been consolidated as In re NantKwest, Inc. Derivative Litigation, Cons. C.A. No. 2017-0774- Sudunagunta Bushansky On February 5, 2018, the defendants filed a motion to dismiss the consolidated complaint. At this time, the Company cannot predict how the Court will rule on the merits of the claims and/or the scope of the potential loss in the event of an adverse outcome. Therefore, based on the information available at present, the Company cannot reasonably estimate a range of loss for this action. Should the Company ultimately be found liable, the liability could have a material adverse effect on the Company’s results of operations for the period or periods in which it is incurred. Insurance Recoveries The Company has reflected its right to insurance recoveries, limited to the extent of incurred or probable losses, as a receivable when such recoveries have been agreed to with its third-party insurers and receipt is deemed probable. This includes instances where the Company’s third-party insurers have agreed to reimburse certain legal defense costs incurred with applicable law firms by the Company. The amount of such receivable recorded at March 31, 2018 was $1.6 million included in prepaid expenses and current assets on the Company’s condensed consolidated balance sheet. Contractual Obligations - Leases The Company leases: (i) office space in Cardiff-by-the-Sea, California; (ii) a research facility in Woburn, Massachusetts; (iii) a research facility and office space in San Diego, California; (iv) research and manufacturing space in Culver City, California, from a related party (Note 9); and (v) a research and manufacturing facility in El Segundo, California, also from a related party (Note 9). The Company recognizes rent expense under its operating leases on a straight-line basis. Rent expense for the three months ended March 31, 2018 and 2017 was $0.7 million for both periods. Build-to-suit Lease In September 2016, the Company entered into a lease agreement with 605 Doug St, LLC, a related party (Note 9), for approximately 24,250 square feet in El Segundo, California, which is to be converted to a research and development laboratory and a current Good Manufacturing Practices (cGMP) manufacturing facility. The lease runs from July 2016 through July 2023. The Company has the option to extend the lease for an additional three year term through July 2026. The monthly rent is $0.1 million with annual increases of 3% beginning in July 2017. During the construction period, the Company records the rent payments as (1) a reduction of the build-to-suit lease liability; (2) deferred rent; and (3) rent expense on the imputed cost to lease the underlying land of the facility, which is considered an operating lease. For the three months ended March 31, 2018 and 2017, the Company recorded $0.1 million for both periods in rent expense, which is recorded in research and development expense on the condensed consolidated statement of operations. The Company is responsible for costs to build out the facility and has incurred costs of approximately $30.1 million as of March 31, 2018, which is reflected in construction in progress as part of property, plant and equipment, net on the condensed consolidated balance sheet. Additionally, in order for the facility to meet the Company's research and development laboratory and cGMP specifications, the Company started to make certain structural changes to the facility as part of the conversion. As a result of these changes, the Company concluded that it is the “deemed owner” of the building (for accounting purposes only) during the construction period. Accordingly, the Company recorded a non-cash build-to-suit lease asset of $5.1 million, representing its estimate of the fair market value of the building, and a corresponding construction build-to-suit lease liability, recorded as a component of other current and non-current liabilities on the condensed consolidated balance sheet as of March 31, 2018. Upon completion of construction of this facility, the Company evaluates the de-recognition of the asset and liability under the provisions of ASC 840-40 Leases - Sale-Leaseback Transactions Financing Lease Obligation In November 2015, the Company entered into a facility license agreement with NantWorks LLC (NantWorks) (Note 9) for approximately 9,500 square feet of office space in Culver City, California, which has been converted to a research and development laboratory and a cGMP manufacturing facility. The license was effective in May 2015 and extends through December 2020. The Company has the option to extend the license through December 2023. The monthly license fee is $47,000 with annual increases of 3% beginning in January 2017. The Company records the rent payments as (1) a reduction of the financing obligation; (2) imputed interest expense; and (3) rent expense on the imputed cost to lease the underlying land of the facility, which is considered an operating lease. For the three months ended March 31, 2018 and 2017, the Company recorded $47,000 for both periods in rent expense, which is reflected in research and development expense in the condensed consolidated statement of operations. Under the facility license agreement, the Company was responsible for costs to build out the laboratory and manufacturing facility space and incurred costs of approximately $3.5 million. The Company concluded that it was the “deemed owner” of the building (for accounting purposes only) during the construction period. The Company recorded the build out costs as an asset with a corresponding build-to-suit liability, which was recorded as a component of other current and non-current liabilities in the condensed consolidated balance sheet while the building was under construction. Upon completion of construction of this building in August 2016, the Company evaluated the de-recognition of the asset and liability under the provisions of ASC 840-40, Leases – Sale-Leaseback Transactions. Commitments The Company did not enter into any significant contracts during the three months ended March 31, 2018 other than those disclosed in this document . |

The Company expects to benefit from the preclinical and clinical research conducted during the first and second year under this agreement and is providing the first and second year funding under the five-year agreement. In both April 2016 and April 2017, the Company paid $0.6 million to the National Cancer Institute as a prepayment for the first and second year of funding. The Company recognizes research and development expense ratably over a 12 month period for each funding year and recorded $0.1 million of expense for both periods for the three months ended March 31, 2018 and 2017. NantWorks Under the NantWorks shared services agreement executed in November 2015, but effective August 2015, NantWorks provides corporate, general and administrative, manufacturing strategy, research and development, regulatory and clinical trial strategy and other support services. The Company is charged for the services at cost plus reasonable allocations for indirect costs that relate to the employees providing the services. For the three months ended March 31, 2018 and 2017, the Company recorded selling, general and administrative expense of $0.8 million and $1.2 million, respectively. For the three months ended March 31, 2018 and 2017, the Company recorded research and development expense of $0.9 million and $0.8 million, respectively, under this arrangement on the condensed consolidated statement of operations. These amounts exclude certain general and administrative expenses provided by third party vendors directly for the Company’s benefit, which have been reimbursed to NantWorks based on those vendors’ invoiced amounts without markup by NantWorks. In November 2015, the Company entered into a facility license agreement with NantWorks, which became effective May 2015, for approximately 9,500 square feet in Culver City, California, which has been converted to a research and development laboratory and a cGMP manufacturing facility. See Note 8 - Financing Lease Obligation NantOmics, LLC In June 2015, the Company entered into an agreement with NantOmics, LLC (NantOmics), an affiliate of NantWorks, to obtain genomic sequencing and proteomic analysis services, as well as related data management and bioinformatics services, exclusively from NantOmics. The Company will have rights to use the data and results generated from NantOmics’ services in connection with the performance of the particular oncology trial with respect to which the services were performed, but NantOmics will own the data and results, as well as any other intellectual property it creates in performing these services on the Company’s behalf. The Company is obligated to pay NantOmics a fixed, per sample fee, determined based on the type of services being provided. The agreement has an initial term of five years and renews automatically for successive one year periods, unless terminated earlier. For the three months ended March 31, 2018 and 2017, the Company recorded operating expense of $42,000 and $0, respectively, under the agreement to research and development expense on the condensed consolidated statement of operations. At March 31, 2018, the Company owes NantOmics $0.1 million. NantCell In June 2015, the Company also entered into a supply agreement with NantCell, a majority owned subsidiary of NantWorks, pursuant to which the Company has the right to purchase NantCell’s proprietary bioreactors, made according to specifications mutually agreed to with NantCell. The Company also has the right to purchase reagents and consumables associated with such equipment from NantCell. When an upfront payment is made, it is included in prepaid expenses on the condensed consolidated balance sheets until the product is received. The agreement has an initial term of five years and renews automatically for successive one year periods unless terminated earlier. During the three months ended March 31, 2018 and 2017, the Company recorded research and development expense of $0 and $0.3 million, respectively, on the condensed consolidated statement of operations. At March 31, 2018, the Company owed NantCell $0 and has a prepaid balance of $0.2 million included in prepaid expenses and other current assets on the condensed consolidated balance sheet. |

Stockholders' Equity | 10. Stockholders’ Equity Stock Repurchase— In November 2015, the board of directors approved a share repurchase program (2015 Share Repurchase Program) allowing the CEO or CFO, on behalf of the Company, to repurchase from time to time, in the open market or in privately negotiated transactions, up to $50.0 million of the Company’s outstanding shares of common stock, exclusive of any commissions, markups or expenses. The timing and amounts of any purchases will be based on market conditions and other factors, including price, regulatory requirements and other corporate considerations. The 2015 Share Repurchase Program does not require the purchase of any minimum number of shares and may be suspended, modified or discontinued at any time without prior notice. The Company expects to finance the purchases with existing cash balances. At March 31, 2018, $19.1 million remained authorized for repurchase under the Company’s 2015 Share Repurchase Program and no shares were repurchased during the three months ended March 31, 2018. |

Income Taxes | 12. Income Taxes The difference between the federal statutory tax rate of 21% and the Company’s 0% tax rate is due to losses in jurisdictions from which the Company cannot benefit. Intraperiod tax allocation rules require the Company to allocate the provision for income taxes between continuing operations and other categories of earnings, such as other comprehensive income. In periods in which the Company has a year-to-date pre-tax loss from continuing operations and pre-tax income in other categories of earnings, such as other comprehensive income, the Company must allocate the tax provision to the other categories of earnings. The Company then records a related tax benefit in continuing operations. The Company did not record any unrealized gains in other comprehensive income during the three months ended March 31, 2018. The Company did record unrealized gains in other comprehensive income during the three months ended March 31, 2017. As a result, the Company recorded a tax benefit of $0 and $6,000 for the three months ended March 31, 2018 and 2017, respectively, on the condensed consolidated statement of operations and $0 and $ 26,000, respectively, in other comprehensive income on the condensed consolidated balance sheet. The Company is operating in Korea. During the three months ended March 31, 2018 and 2017, the tax benefit related to Korea is $0.1 million for each period. The Company currently files federal and state income tax returns in the United States and in Korea. Income tax expense consists of U.S. federal, state, and Korean income taxes. To date, the Company has not been required to pay U.S. federal income taxes because of current and accumulated net operating losses.

Accounting Policies [Abstract] | |
Liquidity | Liquidity As of March 31, 2018, the Company had an accumulated deficit of approximately $526.0 million. The Company also had negative cash flow from operations of approximately $15.5 million during the three months ended March 31, 2018. The Company expects that it will likely need additional capital to further fund development of, and seek regulatory approvals for, its product candidates, and begin to commercialize any approved products. The Company is currently focused primarily on the development of immunotherapeutic treatments for cancers and debilitating viral infections using targeted cancer killing cell lines, and believes such activities will result in the Company’s continued incurrence of significant research and development and other expenses related to those programs. If the clinical trials for any of the Company’s product candidates fail or produce unsuccessful results and those product candidates do not gain regulatory approval, or if any of the Company’s product candidates, if approved, fail to achieve market acceptance, the Company may never become profitable. Even if the Company achieves profitability in the future, it may not be able to sustain profitability in subsequent periods. The Company intends to cover its future operating expenses through cash and cash equivalents and marketable debt securities on hand and through a combination of equity offerings, debt financings, government or other third-party funding, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements. Additional financing may not be available to the Company when needed and, if available, financing may not be obtained on terms favorable to the Company or its stockholders. While the Company expects its existing cash and cash equivalents and marketable debt securities will enable it to fund operations and capital expenditure requirements for at least the next twelve months, it may not have sufficient funds to reach commercialization. Failure to obtain adequate financing when needed may require the Company to delay, reduce, limit or terminate some or all of its development programs or future commercialization efforts or grant rights to develop and market product candidates that the Company might otherwise prefer to develop and market itself which could adversely affect the Company’s ability to operate as a going concern. If the Company raises additional funds from the issuance of equity securities, substantial dilution to existing stockholders may result. If the Company raises additional funds by incurring debt financing, the terms of the debt may involve significant cash payment obligations as well as covenants and specific financial ratios that may restrict the Company’s ability to operate its business. |
Principles of Consolidation and Equity Investments | Principles of Consolidation and Equity Investments The Company’s condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Inex Bio, Inc. and 557 Doug St, LLC, and have been prepared in accordance with GAAP. All intercompany amounts have been eliminated. The Company applies the variable interest model under Accounting Standards Codification (ASC) Topic 810, Consolidation For entities the Company holds as an equity investment and are not consolidated under the VIE Model, the Company considers whether its investment constitutes ownership of a majority of the voting interests in the entity and therefore should be considered for consolidation under the voting interest model. Unconsolidated equity investments in the common stock or in-substance common stock of an entity under which the Company is able to exercise significant influence, but not control, are accounted for using the equity method. The Company’s ability to exercise significant influence is generally indicated by ownership of 20 to 50 percent interest in the voting securities of the entity. All other unconsolidated equity investments on which the Company is not able to exercise significant influence will be subsequently measured at fair value with unrealized |
Use of Estimates | Use of Estimates The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to stock-based compensation, the valuation allowance for deferred tax assets, preclinical and clinical trial accruals, impairment assessments, and the valuation of build-to-suit lease assets. The Company bases its estimates on historical experience and on various other market-specific and relevant assumptions that it believes to be reasonable under the circumstances. Actual results could differ from those estimates. |
Basic and Diluted Net Loss Per Share of Common Stock | Basic and Diluted Net Loss per Share of Common Stock Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding for the period. Diluted loss per share is computed similarly to basic loss per share except that the denominator is increased to include the number of additional shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive. For all periods presented, potentially dilutive securities are excluded from the computation of fully diluted loss per share as their effect is anti-dilutive. The following table details those securities that have been excluded from the computation of potentially dilutive securities: As of March 31, 2018 2017 Outstanding options 5,693,250 5,693,250 Outstanding restricted stock units 874,164 1,060,381 Outstanding warrants 17,706,818 17,768,314 Total 24,274,232 24,521,945 Amounts in the table above reflect the common stock equivalents of the noted instruments. |
Recently Adopted Accounting Policies | Recently Adopted Accounting Policies Financial Assets and Liabilities and Equity Investment Effective January 1, 2018, the Company adopted Accounting Standard Update (ASU) 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities The Company owns non-marketable equity securities that are accounted for as an equity investment at cost minus impairment and plus or minus changes resulting from observable price changes because the preferred stock held by the Company is not considered in-substance common stock and such preferred stock does not have a readily determinable fair value. All investments are reviewed on a regular basis for possible impairment. If an investment's fair value is determined to be less than its net carrying value, the investment is written down to its fair value. Such an evaluation is judgmental and dependent on specific facts and circumstances. Factors considered in determining whether an impairment indicator is present include: the investees’ earning performance and clinical trial performance, change in the investees’ industry and geographic area in which it operates, offers to purchase or sell the security for a price less than the cost of the investment, issues that raise concerns about the investee's ability to continue as a going concern and any other information that the Company may be aware of related to the investment. Factors considered in determining whether an observable price change has occurred include: the price at which the investee issues equity instruments similar to those of the Company’s investment and the rights and preferences of those equity instruments compared to the Company’s. Revenue Recognition Beginning January 1, 2018, the Company follows the provisions of ASC Topic 606, Revenue from Contracts with Customers The Company derives substantially all of its revenue from non-exclusive license agreements with a limited number of pharmaceutical and biotechnology companies granting them the right to use the Company’s cell lines and intellectual property for non-clinical use. These agreements generally include upfront fees and annual research license fees for such use, as well as commercial license fees for sales of the Company’s licensee’s products developed or manufactured using the Company’s intellectual property and cell lines. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC Topic 606. A contract’s transaction price is allocated to each distinct performance obligation based on relative standalone selling price and recognized as revenue when, or as, the performance obligation is satisfied. Under the Company’s license agreements with customers, the Company typically promises to provide a license to use certain cell lines and related patents, the related know-how, and future research and development data that affects the license. The Company concluded that these promises represent one performance obligation due to the highly interrelated nature of the promises. The Company provides the cell lines and know-how immediately upon entering into the contracts. The research and development data is provided throughout the term of the contract when and if available. The Company’s license agreement with Intrexon included a nonrefundable upfront payment of $0.4 million, received when the Company entered into the contract in 2010. In this instance, the Company determined that under ASC 606 it would be appropriate to recognize the initial milestone payment at a point in time, when it transferred the license. In this case, the intellectual property provided under the contract is functional intellectual property under ASC 606 and was determined to be a distinct performance obligation in the context of the arrangement. Prior to adoption, the upfront payment had been initially recorded as deferred revenue and was being recognized into revenue on a straight-line basis. As a result, upon adoption of ASC 606, the Company adjusted its opening retained deficit for the effects of recognizing revenue upfront for the initial milestone. The adjustment to opening retained deficit upon adoption was not material. The license agreements may include nonrefundable upfront payments, event-based milestone payments, sales-based royalty payments, or some combination of these. The event-based milestone payments represent variable consideration and the Company uses the most likely amount method to estimate this variable consideration. Given the high degree of uncertainly around achievement of these milestones, the Company does not recognize revenue from these milestone payments until the uncertainty associated with these payments is resolved. The Company currently estimates variable consideration related to milestone payments to be zero and, as such, no revenue has been recognized for milestone payments. The Company will recognize revenue from sales-based royalty payments when or as the sales occur. On a quarterly basis, the Company will re-evaluate its estimate of milestone variable consideration to determine whether any amount should be included in the transaction price and recorded in revenue prospectively. Upon adoption, the Company changed its accounting policy from accounting for milestones payments under the milestone method to accounting for variable consideration as discussed above. The change in accounting policy did not change any amounts in the financial statements because of the significant uncertainty surrounding the estimate of variable consideration for milestone payments. The Company’s revenue from non-clinical license agreements is nominal. In the future, the Company may generate revenue from license agreements entered into for therapeutic uses. To date, the Company has not generated any revenue from product sales. If the Company fails to complete the development of its product candidates in a timely manner or fails to obtain regulatory approval for them, the Company may never be able to generate substantial future revenue. Statement of Cash Flows Effective January 1, 2018, the Company adopted ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments . ASU 2016-15 adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. Also, effective January 1, 2018, the Company adopted Statement of Cash Flows: Restricted Cash, a consensus of the FASB’s Emerging Issues Task Force . ASU 2016-18 requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Entities will also be required to reconcile such total to amounts on the balance sheet and disclose the nature of the restrictions. Both Updates will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual periods. Prior periods were retrospectively adjusted to conform to the current period’s presentation. There was no material impact on the Company’s statement of cash flows on adoption of either Update. |
