12. License Agreements

Rucaparib

In June 2011, we entered into a worldwide license agreement with Pfizer, Inc. to acquire exclusive development and commercialization rights to rucaparib. This drug candidate is a small molecule inhibitor of poly (ADP-ribose) polymerase (PARP), which we are developing for the treatment of selected solid tumors. Under the terms of the license agreement, we made a $7.0 million upfront payment to Pfizer. In April 2014, we initiated a pivotal registration study for rucaparib, which resulted in a $0.4 million milestone payment to Pfizer as required by the license agreement. In September 2016, we made a milestone payment of $0.5 million to Pfizer upon acceptance of the NDA for rucaparib by the FDA. These payments were recognized as acquired in-process research and development expense.

We are responsible for all development and commercialization costs of rucaparib. When and if commercial sales of rucaparib begin, we will pay Pfizer tiered royalties on our net sales. In addition, Pfizer is eligible to receive up to $264.5 million of further payments, in aggregate, if certain development, regulatory and sales milestones are achieved, including $21.25 million associated with the first filing and approval of a New Drug Application (“NDA”) by the FDA. During the second quarter of 2016, we completed the submission of our NDA with the FDA for potential accelerated approval of rucaparib in the U.S. The FDA granted the rucaparib NDA priority review status with a Prescription Drug User Fee Act action date of February 23, 2017. During the fourth quarter of 2016, we submitted a Marketing Authorization Application (“MAA”) for rucaparib to the European Medicines Agency (“EMA”).

On August 30, 2016, we entered into a first amendment to the worldwide license agreement with Pfizer, which amends the June 2011 existing worldwide license agreement to permit us to defer payment of the milestone payments payable upon (i) FDA approval of an NDA for 1^st Indication in US and (ii) EMA approval of an MAA for 1^st Indication in EU, to a date that is 18 months after the date of achievement of such milestones. In the event that we defer such milestone payments, we have agreed to certain higher payments related to the achievement of such milestones.

Lucitanib

In connection with its acquisition of EOS (see Note 3), we gained rights to develop and commercialize lucitanib, an oral, selective tyrosine kinase inhibitor. As further described below, EOS licensed the worldwide rights, excluding China, to develop and commercialize lucitanib from Advenchen Laboratories LLC (“Advenchen”). Subsequently, rights to develop and commercialize lucitanib in markets outside the U.S. and Japan were sublicensed by EOS to Les Laboratoires Servier (“Servier”) in exchange for upfront milestone fees, royalties on sales of lucitanib in the sublicensed territories and research and development funding commitments.

In October 2008, EOS entered into an exclusive license agreement with Advenchen to develop and commercialize lucitanib on a global basis, excluding China. We are obligated to pay Advenchen royalties on net sales of lucitanib based on the volume of annual net sales achieved. In addition, we are obligated to pay to Advenchen 25% of any consideration, excluding royalties, received pursuant to any sublicense agreements for lucitanib, including the agreement with Servier. In the first quarter of 2014, we recognized acquired in-process research and development expense of $3.4 million, which represents 25% of the sublicense agreement consideration of $13.6 million received from Servier upon the end of opposition and appeal of the lucitanib patent by the European Patent Office.

In September 2012, EOS entered into a collaboration and license agreement with Servier whereby EOS sublicensed to Servier exclusive rights to develop and commercialize lucitanib in all countries outside of the U.S., Japan and China. In exchange for these rights, EOS received an upfront payment of €45.0 million and is entitled to receive additional payments upon achievement of specified development, regulatory and commercial milestones up to €90.0 million in the aggregate. In addition, we are entitled to receive sales milestone payments if specified annual sales targets for lucitanib are met, which, in the aggregate, could total €250.0 million. We are also entitled to receive royalties on sales of lucitanib by Servier.

The development, regulatory and commercial milestones represent non-refundable amounts that would be paid by Servier to us if certain milestones are achieved in the future. These milestones, if achieved, are substantive as they relate solely to past performance, are commensurate with estimated enhancement of value associated with the achievement of each milestone as a result of our performance, which are reasonable relative to the other deliverables and terms of the arrangement, and are unrelated to the delivery of any further elements under the arrangement.

We and Servier are developing lucitanib pursuant to a development plan agreed to between the parties. Servier is responsible for all of the initial global development costs under the agreed upon plan up to €80.0 million. Cumulative global development costs, if any, in excess of €80.0 million will be shared equally between us and Servier. During the second quarter of 2016, we and Servier agreed to discontinue the development of lucitanib for breast cancer and are continuing to evaluate, what, if any, further development of lucitanib will be pursued. Based on current estimates, we expect to complete the committed on-going development activities in 2017 and expect full reimbursement of our development costs from Servier. Reimbursements are recorded as a reduction to research and development expense on the Consolidated Statements of Operations.

We recorded a $1.3 million and $3.2 million receivable at September 30, 2016 and December 31, 2015, respectively, for the reimbursable development costs incurred under the global development plan, which is included in other current assets on the Consolidated Balance Sheets. For the three months ending September 30, 2016 and 2015, we incurred $1.3 million and $3.8 million, respectively, in research and development costs and recorded reductions in research and development expense of $1.3 million and $3.8 million, respectively, for reimbursable development costs due from Servier. For the nine months ending September 30, 2016 and 2015, respectively, we incurred $7.4 million and $11.7 million, respectively, in research and development costs and recorded reductions in research and development expense of $7.7 million and $10.4 million, respectively, for reimbursable development costs due from Servier.

Rociletinib

In May 2010, we entered into an exclusive worldwide license agreement with Avila Therapeutics, Inc. (now Celgene Avilomics Research, Inc., part of Celgene Corporation (“Celgene”)) to discover, develop and commercialize a covalent inhibitor of mutant forms of the epidermal growth factor receptor gene product. Rociletinib was identified as the lead inhibitor candidate under the license agreement. We are responsible for all non-clinical, clinical, regulatory and other activities necessary to develop and commercialize rociletinib.

We made an upfront payment of $2.0 million upon execution of the license agreement, a $4.0 million milestone payment in the first quarter of 2012 upon acceptance by the FDA of our Investigational New Drug application for rociletinib and a $5.0 million milestone payment in the first quarter of 2014 upon initiation of the Phase II study for rociletinib. In the third quarter of 2015, we made milestone payments totaling $12.0 million upon acceptance of the NDA and MAA for rociletinib by the FDA and EMA, respectively. We recognized all payments as acquired in-process research and development expense.

During the second quarter of 2016, we received a Complete Response Letter (“CRL”) from the FDA for the rociletinib NDA. The FDA issues a CRL to indicate that their review of an application is complete and that the application is not ready for approval. In anticipation of receiving the CRL, we terminated enrollment in all ongoing sponsored clinical studies, although we continue to provide drug to patients whose clinicians recommend continuing rociletinib therapy. In addition, we withdrew our MAA for rociletinib on file with the EMA. We are continuing analyses of rociletinib data to determine whether certain populations of patients may represent an opportunity for a partner committed to investing in further clinical development.

We are obligated to pay royalties on net sales of rociletinib based on the volume of annual net sales achieved. We are required to pay up to an additional aggregate of $98.0 million in development and regulatory milestone payments if certain clinical study objectives and regulatory filings, acceptances and approvals are achieved. In addition, we are required to pay up to an aggregate of $120.0 million in sales milestone payments if certain annual sales targets are achieved.
