| Collaboration Agreements | COLLABORATION AGREEMENTS Ipsen Collaboration In February 2016, we entered into a collaboration and license agreement (the “Ipsen Collaboration Agreement”) with Ipsen Pharma SAS (“Ipsen”) for the commercialization and further development of cabozantinib. Pursuant to the terms of the Ipsen Collaboration Agreement, Ipsen received exclusive commercialization rights for current and potential future cabozantinib indications outside of the U.S., Canada and Japan (the “Ipsen Territory”). The Ipsen Collaboration Agreement was subsequently amended in December 2016 (the “Amendment”) to include commercialization rights in Canada in the Ipsen Territory. We have also agreed to collaborate with Ipsen on the development of cabozantinib for current and potential future indications. In consideration for the exclusive license and other rights contained in the Ipsen Collaboration Agreement, Ipsen paid us an upfront nonrefundable payment of $200.0 million in March 2016. Additionally, as a result of the Amendment, we received a $10.0 million upfront nonrefundable payment from Ipsen in December 2016 and, as a result of the approval of cabozantinib in second-line RCC by the European Commission (“EC”) in September 2016, we received a $60.0 million milestone in November 2016. We are receiving a 2% royalty on the initial $50.0 million of net sales by Ipsen, and are entitled to receive a 12% royalty on the next $100.0 million of net sales by Ipsen. After the initial $150.0 million of sales, we are entitled to receive a tiered royalty of 22% to 26% on annual net sales by Ipsen; these tiers will reset each calendar year. We are primarily responsible for funding cabozantinib-related development costs for those trials in existence at the time we entered into the Ipsen Collaboration Agreement; global development costs for additional trials will be shared between the parties, with Ipsen reimbursing us for 35% of such costs, provided Ipsen opts in to participate in such additional trials. Pursuant to the terms of the Ipsen Collaboration Agreement, we will remain responsible for the manufacture and supply of cabozantinib for all development and commercialization activities. As part of the collaboration agreement, we entered into a supply agreement pursuant to which we will supply finished, labeled product to Ipsen for distribution in the Ipsen Territories at our cost, as defined in the agreement, which excludes the 3% royalty we are required to pay GlaxoSmithKline (“GSK”) on Ipsen’s Net Sales of any product incorporating cabozantinib. The Ipsen Collaboration Agreement contains multiple deliverables consisting of intellectual property licenses, delivery of products and/or materials containing cabozantinib to Ipsen for all development and commercial activities, research and development services, and participation on the joint steering, development and commercialization committees (as defined in the Ipsen Collaboration Agreement). We determined that these deliverables do not have stand-alone value and accordingly, combined these deliverables into a single unit of accounting and allocated the entire arrangement consideration to that combined unit of accounting. As a result, the upfront payment of $200.0 million , received in the first quarter of 2016 and the $10.0 million upfront payment received in December 2016 in consideration for the development and commercialization rights in Canada are being recognized ratably over the term of the Ipsen Collaboration Agreement, through early 2030, which is the current estimated patent expiration of cabozantinib in the European Union. At the time we entered into the Ipsen Collaboration Agreement, we also determined that the $60.0 million milestone we achieved upon the approval of cabozantinib by the EC in second-line RCC was not substantive due to the relatively low degree of uncertainty and relatively low amount of effort required on our part to achieve the milestone as of the date of the collaboration agreement; the $60.0 million was deferred entirely until the date of the European Medicines Agency’s approval of cabozantinib in second-line RCC in September 2016 and has since been recognized ratably over the remainder of the term of the Ipsen Collaboration Agreement. The two $10.0 million milestones for the first commercial sales of CABOMETYX in Germany and the United Kingdom were determined to be substantive at the time we entered into the Ipsen Collaboration Agreement and were recognized as collaboration revenues in the fourth quarter of 2016. We determined that the remaining development and regulatory milestones are substantive and will be recognized as revenue in the periods in which they are achieved. We consider the contingent payments due to us upon the achievement of specified sales volumes to be similar to royalty payments. Reimbursements for development costs are classified as revenue as the development services represent our ongoing major or central operations. During the three months ended March 31, 2017, we reclassified $9.0 million of deferred revenue to Accrued collaboration liabilities and Other long-term liabilities, and accordingly adjusted our amortization of the upfront payment of $200.0 million as a result of a change in operational responsibilities for certain clinical programs in the Ipsen Territory. As of June 30, 2017 , we had paid $2.1 million toward the $9.0 million of reimbursements due to Ipsen for these clinical programs. See “Note 2 - Collaboration Agreements” to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC on February 27, 2017 for additional description of our collaboration agreement with Ipsen. During the three and six months ended June 30, 2017 and 2016 , collaboration revenues under the Ipsen Collaboration Agreement were as follows (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Amortization of upfront payments and deferred milestone $ 4,741 $ 3,592 $ 9,046 $ 4,790 Royalty revenue 219 — 443 — Development cost reimbursements 862 — 1,199 — Product supply agreement revenue 811 — 1,802 — Cost of supplied product (811 ) — (1,802 ) — Royalty payable to GSK on net sales by Ipsen (328 ) — (664 ) — Collaboration revenues under the Ipsen Collaboration Agreement $ 5,494 $ 3,592 $ 10,024 $ 4,790 As of June 30, 2017 , short-term and long-term deferred revenue relating to the Ipsen Collaboration Agreement was $19.0 million and $219.7 million , respectively. Genentech Collaboration In December 2006, we out-licensed the development and commercialization of cobimetinib to Genentech pursuant to a worldwide collaboration agreement (the “Genentech Collaboration Agreement”). Under the terms of the Genentech Collaboration Agreement for cobimetinib, we are entitled to a share of U.S. profits and losses received in connection with the commercialization of cobimetinib. The profit and loss share has multiple tiers: we are entitled to 50% of profits and losses from the first $200.0 million of U.S. actual sales, decreasing to 30% of profits and losses from U.S. actual sales in excess of $400.0 million . In addition, we are entitled to low double-digit royalties on ex-U.S. net sales. In November 2013, we exercised an option under the Genentech Collaboration Agreement to co-promote in the U.S. In 2015, we began fielding 25% of the sales force promoting COTELLIC in combination with Zelboraf as a treatment for patients with BRAF V600E or V600K mutation-positive advanced melanoma. On June 3, 2016, we filed a Demand for Arbitration before JAMS in San Francisco, California asserting claims against Genentech related to its clinical development, pricing and commercialization of COTELLIC, and cost and revenue allocations arising from COTELLIC’s commercialization in the U.S. Our arbitration demand asserted that Genentech breached the Genentech Collaboration Agreement by, amongst other breaches, failing to meet its diligence and good faith obligations. On July 13, 2016, Genentech asserted a counterclaim for breach of contract seeking monetary damages and interest related to the cost allocations under the Genentech Collaboration Agreement. On December 29, 2016, however, Genentech withdrew its counterclaim against us and stated that it would unilaterally change its approach to the allocation of promotional expenses arising from commercialization of the COTELLIC plus Zelboraf combination therapy, both retrospectively and prospectively. The revised allocation approach substantially reduced our exposure to costs associated with promotion of the COTELLIC plus Zelboraf combination in the U.S. However, other significant issues remained in dispute between the parties as of June 30, 2017 . Genentech’s action did not address the claims in our demand for arbitration related to Genentech’s clinical development of cobimetinib, or pricing or promotional costs for COTELLIC in the U.S. and it did not fully resolve claims over revenue allocation. In addition, Genentech’s unilateral action did not clarify how it intended to allocate promotional costs incurred with respect to the promotion of other combination therapies that include cobimetinib for other indications that may be developed or are in development and may be approved. As a result, we continued to press our position before the arbitral panel to obtain a just resolution of these claims. On June 8, 2017, the parties settled the arbitration, which was dismissed with prejudice. The settlement does not provide for payments in settlement of the asserted claims; as part of the settlement, on July 19, 2017, we entered into an amendment to the Genentech Collaboration Agreement (the “Genentech Amendment”) which provides for a revised revenue and cost-sharing arrangement, effective as of July 1, 2017, that is applicable to current and potential future commercial uses of COTELLIC. See “Note 13 - Subsequent Event” for a further description of the Genentech Amendment. During the three and six months ended June 30, 2017 and 2016 , ex-U.S. royalty revenues and U.S. losses under the Genentech Collaboration Agreement were as follows (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Royalty revenues on ex-U.S. sales of COTELLIC included in Collaboration revenues $ 1,367 $ 1,042 $ 3,665 $ 1,172 U.S. losses included in Selling, general and administrative expenses (1) $ (781 ) $ (4,630 ) $ (1,407 ) $ (11,923 ) ____________________ (1) A portion of the accrual for losses for three and six months ended June 30, 2016 were reversed in December 2016 when we were relieved of our obligation to pay certain disputed costs as a result of Genentech’s unilaterally change to its approach to the allocation of promotional expenses arising from commercialization of the COTELLIC plus Zelboraf combination therapy. The U.S. losses under the Genentech Collaboration Agreement include our share of the net loss from the collaboration, as well as personnel and other costs we have incurred to co-promote COTELLIC plus Zelboraf in the U.S. Royalty revenues from the Genentech Collaboration Agreement are based on amounts reported to us by Genentech and are recorded when such information becomes available to us. For prior periods, from the launch of COTELLIC through December 31, 2016, such information was not available until the following quarter, meaning that historically we recorded royalty revenues on a one quarter lag. Beginning in 2017, such information became available to us in the current quarter. As a result of this change, during the six months ended June 30, 2017 , in addition to the royalties reported to us for that period we also recorded $1.1 million in royalties for the sales activity related to the three months ended December 31, 2016. Takeda Collaboration On January 30, 2017, we entered into a collaboration and license agreement (the “Takeda Collaboration Agreement”) with Takeda Pharmaceutical Company Ltd. (“Takeda”) for the commercialization and further clinical development of cabozantinib in Japan. Pursuant to the terms of the Takeda Collaboration Agreement, Takeda will have exclusive commercialization rights for current and potential future cabozantinib indications in Japan. The companies have also agreed to collaborate on the clinical development of cabozantinib in Japan. The operation and strategic direction of the parties’ collaboration will be governed through a joint executive committee and appropriate subcommittees. In consideration for the exclusive license and other rights contained in the Takeda Collaboration Agreement, Takeda paid us an upfront nonrefundable payment of $50.0 million in February 2017. We will be eligible to receive development, regulatory and first-sales milestones of up to $95.0 million related to second-line RCC, first-line RCC and second-line hepatocellular carcinoma (“HCC”), as well as additional development, regulatory and first-sales milestone payments for potential future indications. The Takeda Collaboration Agreement also provides that we will be eligible to receive pre-specified payments of up to $83.0 million associated with potential sales milestones. We will also receive royalties on net sales of cabozantinib in Japan at an initial tiered rate of 15% to 24% on net sales for the first $300.0 million of cumulative net sales. Thereafter, the royalty rate will be adjusted to 20% to 30% on annual net sales. Takeda will be responsible for 20% of the costs associated with the global cabozantinib development plan’s current and future trials, provided Takeda opts to participate in such future trials, and 100% of costs associated with the cabozantinib development activities that are exclusively for the benefit of Japan. Pursuant to the terms of the Takeda Collaboration Agreement, we will remain responsible for the manufacture and supply of cabozantinib for all development and commercialization activities under the collaboration. As part of the collaboration, the parties will enter into appropriate supply agreements for the manufacture and supply of cabozantinib for Takeda’s territory. During the three and six months ended June 30, 2017 , collaboration revenues under the Takeda Collaboration Agreement were as follows (in thousands): Three Months Ended June 30, 2017 Six Months Ended June 30, 2017 Amortization of upfront payment $ 2,830 $ 4,717 Development cost reimbursements 1,313 2,108 Collaboration revenues under the Takeda Collaboration Agreement $ 4,143 $ 6,825 There was no such revenue during the comparable periods in 2016. As of June 30, 2017 , short-term and long-term deferred revenue relating to the Takeda Collaboration Agreement was $11.3 million and $34.0 million , respectively. The Takeda Collaboration Agreement may be terminated for cause by either party based on uncured material breach by the other party, bankruptcy of the other party or for safety reasons. For clarity, Takeda’s failure to achieve specified levels of commercial performance, based upon sales volume and/or promotional effort, during the first six years following the first commercial sale of cabozantinib in Japan shall constitute a material breach of the Takeda Collaboration Agreement. We may terminate the agreement if Takeda challenges or opposes any patent covered by the Takeda Collaboration Agreement. At any time prior to August 1, 2023, the parties may mutually agree to terminate the Takeda Collaboration Agreement if Japan’s Pharmaceuticals and Medical Devices Agency is unlikely to grant approval of the marketing authorization application in any cancer indication in Japan. After the commercial launch of cabozantinib in Japan, Takeda may terminate the Takeda Collaboration Agreement upon twelve months ’ prior written notice following the third anniversary of the first commercial sale of cabozantinib in Japan. Upon termination by either party, all licenses granted by us to Takeda will automatically terminate, and the licenses granted by Takeda to us shall survive such termination and shall automatically become worldwide. The Takeda Collaboration Agreement contains multiple deliverables consisting of intellectual property licenses, delivery of products and/or materials containing cabozantinib to Takeda for all development and commercial activities, research and development services, and participation on the joint executive, development and commercialization committees (as defined in the Takeda Collaboration Agreement). We determined that these deliverables, other than the commercial supply and joint commercialization committee participation, are non-contingent in nature. The commercial supply deliverable was deemed contingent, primarily due to the fact that there is uncertainty around approval in Japan, which is dependent on successful bridging study results. We also determined that the non-contingent deliverables do not have stand-alone value, because each one of them has value only if we meet our obligation as a whole to provide Takeda with research and development services, including clinical supply of cabozantinib under the Takeda Collaboration Agreement. Accordingly, we combined the non-contingent deliverables into a single unit of accounting and allocated the $50.0 million upfront fee to that combined unit of accounting. We also determined that the level of effort required of us to meet our obligations under the Takeda Collaboration Agreement is not expected to vary significantly over the development period of the Takeda Collaboration Agreement. As a result, the upfront payment of $50.0 million , received in the first quarter of 2017, will be recognized ratably over the development period of the Takeda Collaboration Agreement of approximately four years . We determined that the development and regulatory milestones are substantive and will be recognized as revenue in the periods in which they are achieved. We consider the contingent payments due to us upon the achievement of specified sales volumes to be similar to royalty payments. We will record reimbursements for development costs as revenue as the development services represent a part of our ongoing major or central operations. Bristol-Myers Squibb Collaboration - First-Line Advanced RCC, Bladder Cancer and HCC Combination Studies In February 2017, we entered into a clinical trial collaboration agreement with Bristol-Myers Squibb Company (the “BMS Collaboration Agreement”) for the purpose of evaluating the combination of cabozantinib with nivolumab or of cabozantinib with nivolumab and ipilimumab in various tumor types, including, in RCC, HCC and bladder cancer. To date, a phase 3 trial in first-line advanced RCC and a phase 2 trial in HCC evaluating the combination have been initiated. Pursuant to the terms of the BMS Collaboration Agreement, each party will grant to the other a non-exclusive, worldwide (within the collaboration territory as defined in the BMS Collaboration Agreement), non-transferable, royalty-free license to use the other party’s compounds in the conduct of each clinical trial. The parties’ efforts will be governed through a joint development committee established to guide and oversee the collaboration’s operation. Each trial will be conducted under a combination Investigational New Drug application, unless otherwise required by a regulatory authority. Each party will be responsible for supplying drug product for the applicable clinical trial in accordance with the terms of the supply agreement entered into between the parties in April 2017, and costs for each such trial will be shared equally between the parties, unless two Bristol-Myers Squibb Company (“BMS”) compounds will be utilized in such trial, in which case BMS will bear two-thirds of the costs for such study treatment arms and we will bear one-third of the costs. Unless earlier terminated, the BMS Collaboration Agreement will remain in effect until the completion of all clinical trials under the collaboration, all related trial data has been delivered to both parties and the completion of any then agreed upon analysis. Ipsen has opted in to participate in the phase 3 pivotal trial in first-line advanced RCC and will have access to the results to support potential future regulatory submissions. Ipsen may also participate in future studies at their choosing. The Roche Group Collaboration In February 2017, we established a clinical trial collaboration with The Roche Group (“Roche”) for the purpose of evaluating the safety and tolerability of cabozantinib in combination with Roche’s atezolizumab in patients with locally advanced or metastatic solid tumors. Each party will be responsible for supplying drug product for the applicable clinical trial in accordance with the terms of the mater clinical supply agreement entered into by the parties in February 2017. Based on the dose-escalation results, the trial has the potential to enroll up to four expansion cohorts, including a cohort of patients with previously untreated advanced clear cell RCC and three cohorts of urothelial carcinoma, namely platinum eligible first-line patients, first or second-line platinum ineligible patients and patients previously treated with platinum-containing chemotherapy. The trial was initiated in June 2017 and is open for enrollment. We are the sponsor of the trial, and Roche is responsible for supplying atezolizumab. Ipsen has opted to participate in the study and will have access to the results to support potential future development in its territories. GlaxoSmithKline Collaboration In October 2002, we established a collaboration with GSK to discover and develop novel therapeutics in the areas of vascular biology, inflammatory disease and oncology. Under the terms of the product development and commercialization agreement, GSK had the right to choose cabozantinib for further development and commercialization, but notified us in October 2008 that it had waived its right to select the compound for such activities. As a result, we retained the rights to develop, commercialize, and license cabozantinib, subject to payment to GSK of a 3% royalty on net sales of any product incorporating cabozantinib. The product development and commercialization agreement was terminated during 2014, although GSK will continue to be entitled to a 3% royalty on net sales of any product incorporating cabozantinib, including COMETRIQ and CABOMETYX. During the three and six months ended June 30, 2017 and 2016 , royalties earned by GSK in connection with the sales of COMETRIQ and CABOMETYX were as follows (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Royalties earned by GSK $ 2,962 $ 946 $ 5,363 $ 1,218 Royalties earned by GSK are included in Cost of goods sold for sales by us and as a reduction of Collaboration revenues for sales by Ipsen in the accompanying Condensed Consolidated Statements of Operations. Other Collaborations During the six months ended June 30, 2017 , we recognized $2.5 million in contract revenues from a milestone payment received from BMS related to its ROR gamma program, and during the six months ended June 30, 2016 , we recognized $5.0 million in contract revenues from a milestone payment received from Merck related to its worldwide license of our phosphoinositide-3 kinase-delta program. There was no such revenue during the three months ended June 30, 2017 or 2016 . See “Note 2 - Collaboration Agreements” to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC on February 27, 2017 for a description of our existing collaboration agreements. |
