Collaborative Licensing And Other Arrangements [Abstract] |
Collaborative, Licensing and Other Arrangements | 4. Collaborative, Licensing and Other Arrangements Novartis On September 30, 2015 (the “Effective Date”), the Company and Novartis entered into a license agreement (the “License Agreement”) under which the Company granted Novartis an exclusive, world-wide, royalty-bearing license to the Company’s anti-transforming growth factor beta (TGFβ) antibody program (the “anti-TGFβ Program”). Under the terms of the License Agreement, Novartis has worldwide rights to the anti-TGFβ Program and is responsible for the development and commercialization of antibodies and products containing antibodies arising from the anti-TGFβ Program. Within 90 days of the Effective Date, the Company completed the transfer of certain proprietary know-how, materials and inventory relating to the anti-TGFβ Program to Novartis. Under the License Agreement, the Company received a $37.0 million upfront fee. The Company is also eligible to receive up to a total of $480.0 million in development, regulatory and commercial milestones. Any such payments will be treated as contingent consideration and recognized as revenue when they are achieved, as the Company has no performance obligations under the License Agreement beyond the initial 90-day period. During the three months ended June 30, 2017, Novartis achieved a clinical development milestone pursuant to the License Agreement and, as a result, the Company earned a $10.0 million milestone payment which was recognized as license and collaborative fees in the condensed consolidated statement of comprehensive income (loss). The $10.0 million was recorded as a trade receivable in the condensed consolidated balance sheet as of June 30, 2017, and payment of such receivable was received in July 2017. Servier In December 2010, the Company entered into a license and collaboration agreement (“Collaboration Agreement”) with Servier, to jointly develop and commercialize gevokizumab in multiple indications. Under the terms of the Collaboration Agreement, Servier had worldwide rights to cardiovascular disease and diabetes indications and had rights outside the United States and Japan to all other indications, including non-infectious intermediate, posterior or pan-uveitis, Behçet’s disease uveitis, pyoderma gangrenosum, and other inflammatory and oncology indications. Under the Collaboration Agreement, Servier funded all activities to advance the global clinical development and future commercialization of gevokizumab in cardiovascular-related diseases and diabetes. Also, Servier funded the first $50.0 million of gevokizumab global clinical development and chemistry, manufacturing and controls expenses related to the three pivotal clinical trials under the EYEGUARD program. All remaining expenses related to these three pivotal clinical trials were shared equally between Servier and the Company. On September 28, 2015, Servier notified XOMA of its intention to terminate the Collaboration Agreement, as amended in January 2015, and return the gevokizumab rights to XOMA. The termination, which became effective on March 25, 2016, did not result in a change to the maturity date of the Company’s loan with Servier (see Note 8). As the Company was no longer required to provide services to Servier under the Collaboration Agreement, the Company recognized all remaining deferred revenue of $0.6 million from the date of notification to March 25, 2016. There was no revenue recognized from this Collaboration Agreement for the three months ended June 30, 2017 and 2016. For the six months ended June 30, 2017 and 2016, the Company recorded revenue of zero and $0.3 million, respectively, from this Collaboration Agreement. NIAID In October 2011, the Company announced that NIAID had awarded the Company a new contract under Contract No. HHSN272201100031C (the “NIAID Contract”) for up to $28.0 million over five years to develop broad-spectrum antitoxins for the treatment of human botulism poisoning. The contract work was being performed on a cost-plus-fixed-fee basis over the life of the contract and the Company was recognizing revenue under the arrangement as the services were performed on a proportional- performance basis. In March 2016, the Company effected a novation of the NIAID Contract to Nanotherapeutics. The novation was effected upon obtaining government approval to transfer the NIAID Contract to Nanotherapeutics pursuant to the asset purchase agreement executed in November 2015 (see Note 6). The Company recognized revenue of zero and $25,000 under this contract for the three months ended June 30, 2017 and 2016, respectively. The Company recognized revenue of zero and $1.1 million under this contract for the six months ended June 30, 2017 and 2016, respectively. Sale of Future Revenue Streams On December 21, 2016, the Company entered into two Royalty Interest Acquisition Agreements (together, the “Acquisition Agreements”) with HealthCare Royalty Partners II, L.P. (“HCRP”). Under the first Acquisition Agreement, the Company sold its right to receive milestone payments and royalties on future sales of products subject to a License Agreement, dated August 18, 2005, between XOMA and Wyeth Pharmaceuticals (subsequently acquired by Pfizer, Inc. (“Pfizer”)) for an upfront cash payment of $6.5 million, plus potential additional payments totaling $4.0 million in the event three specified net sales milestones are met in 2017, 2018 and 2019. Under the second Acquisition Agreement, the Company sold all rights to royalties under an Amended and Restated License Agreement dated October 27, 2006 between XOMA and Dyax Corp. for a cash payment of $11.5 million. The Company classified the proceeds received from HCRP as deferred revenue, to be recognized as contract and other revenue over the life of the license agreements because of the Company's limited continuing involvement in the Acquisition Agreements. Such limited continuing involvement is related to the Company’s undertaking to cooperate with HCRP in the event of litigation or a dispute related to the license agreements. Because the transaction was structured as a non-cancellable sale, the Company does not have significant continuing involvement in the generation of the cash flows due to HCRP and there are no guaranteed rates of return to HCRP, the Company recorded the total proceeds of $18.0 million as deferred revenue. The Company allocated the total proceeds between the two Acquisition Agreements based on the relative fair value of expected payments to be made to HCRP under the license agreements. The deferred revenue is being recognized as contract and other revenue over the life of the underlying license agreements under the "units-of-revenue" method. Under this method, amortization for a reporting period is calculated by computing a ratio of the allocated proceeds received from HCRP to the payments expected to be made by the licensees to HCRP over the term of the Acquisition Agreements, and then applying that ratio to the period’s cash payment. The Company recognized $0.1 million and $0.2 million as contract and other revenue under these arrangements during the three months and six months ended June 30, 2017, respectively. As of June 30, 2017, the current and non-current portion of the remaining deferred revenue was $0.5 million and $17.3 million, respectively. As of December 31, 2016, the Company classified the $18.0 million as non-current deferred revenue.
