Note 10 — License and Collaboration Agreements

We have entered into various collaboration agreements including license agreements and collaborative research, development and commercialization agreements with various pharmaceutical and biotechnology companies. Under these collaboration arrangements, we are entitled to receive license fees, upfront payments, milestone and other contingent payments, royalties, sales milestones, and payments for the manufacture and supply of our proprietary PEGylation materials and/or reimbursement for research and development activities. All of our collaboration agreements are generally cancelable by our partners without significant financial penalty. Our costs of performing these services are generally included in research and development expense, except that costs for product sales to our collaboration partners are included in cost of goods sold.

In accordance with our collaboration agreements, we recognized license, collaboration and other revenue as follows (in thousands):

As of December 31, 2016, our collaboration agreements with partners included potential future payments for development milestones totaling approximately $147.0 million, including amounts from our agreements with Daiichi, Bayer, Baxalta and Ophthotech described below. In addition, under our collaboration agreements we are entitled to receive contingent development payments and contingent sales milestones and royalty payments, including those related to MOVANTIK^® and the MOVANTIK^® fixed-dose combination drug development programs, as described below.

AstraZeneca AB: MOVANTIK^® (naloxegol oxalate), previously referred to as naloxegol and NKTR-118, and MOVANTIK^® fixed-dose combination program, previously referred to as NKTR-119

We are a party to an agreement with AstraZeneca AB (AstraZeneca) under which we granted AstraZeneca a worldwide, exclusive license under our patents and other intellectual property to develop, market, and sell MOVANTIK^® and MOVANTIK^® fixed-dose combination program. AstraZeneca is responsible for all research, development and commercialization and is responsible for all drug development and commercialization decisions for MOVANTIK^® and the MOVANTIK^® fixed-dose combination program. AstraZeneca paid us an upfront payment of $125.0 million, which we received in the fourth quarter of 2009 and which was fully recognized as of December 31, 2010. In addition, we have received the payments described further below based on development events related to MOVANTIK^® completed solely by AstraZeneca. We are entitled to receive up to $75.0 million of commercial launch contingent payments related to the MOVANTIK^® fixed-dose combination program, based on development events to be pursued and completed solely by AstraZeneca. In addition, we are entitled to significant and escalating double-digit royalty payments and sales milestone payments based on annual worldwide net sales of MOVANTIK^® and MOVANTIK^® fixed-dose combination products.

On September 16, 2014, the United States Food and Drug Administration (FDA) approved MOVANTIK^® for the treatment of opioid-induced constipation (OIC) in adult patients with chronic, non-cancer pain. As a result of the FDA’s approval, in 2014 we recognized a total of $105.0 million of payments received from AstraZeneca. On December 9, 2014, AstraZeneca announced that MOVENTIG^® (the naloxegol brand name in the European Union or EU) had been granted Marketing Authorisation by the European Commission (EC) for the treatment of opioid-induced constipation (OIC) in adult patients who have had an inadequate response to laxative(s). In March 2015, AstraZeneca announced that MOVANTIK^® launched in the United States which resulted in our receipt and recognition of a $100.0 million non-refundable commercial launch payment in March 2015. In March 2015, we agreed to pay AstraZeneca a total of $10.0 million to fund U.S. television advertising in consideration for certain additional commercial information rights. We recorded this $10.0 million obligation as a liability and made the initial $5.0 million payment to AstraZeneca in July 2015 and the remaining $5.0 million payment in July 2016. We determined that this $10.0 million obligation should be recorded as a reduction of revenue, which we recorded in 2015. In August 2015, we received and recognized as revenue an additional $40.0 million non-refundable payment triggered by the first commercial sale of MOVENTIG^® in Germany.

On March 1, 2016, AstraZeneca announced that it had entered into an agreement with ProStrakan Group plc, a subsidiary of Kyowa Hakko Kirin Co. Ltd. (Kirin), granting Kirin exclusive marketing rights to MOVENTIG^® in the EU, Iceland, Liechtenstein, Norway and Switzerland. Under the terms of AstraZeneca’s agreement with Kirin, Kirin made a $70.0 million upfront payment to AstraZeneca and will make additional payments based on achieving market access milestones, tiered net sales royalties, as well as sales milestones. Under our license agreement with AstraZeneca, AstraZeneca and we will share the upfront payment, market access milestones, royalties and sales milestones from Kirin with AstraZeneca receiving 60% and Nektar receiving 40%. This payment sharing arrangement is in lieu of other royalties payable by AstraZeneca to us and a portion of the sales milestones as described below. Our 40% share of royalty payments made by Kirin to AstraZeneca will be financially equivalent to us receiving high single-digit to low double-digit royalties dependent on the level of Kirin’s net sales. Kirin’s MOVENTIG^® net sales will be included for purposes of achieving the annual global sales milestones payable to us by AstraZeneca and will also be included for purposes of determining the applicable ex-U.S. royalty rate, from the tier schedule in our AstraZeneca license agreement, that will be applied to ex-U.S. sales outside of the Kirin territory. The global sales milestones under our license agreement with AstraZeneca will be reduced in relation to the amount of Kirin MOVENTIG^® net sales that contribute to any given annual sales milestone target. As a result, in April 2016, we received 40% (or $28.0 million) of the $70.0 million payment received by AstraZeneca from Kirin. In addition, in the year ended December 31, 2016, we recognized another $5.0 million related to our share of similar payments made to AstraZeneca in 2016. As of December 31, 2016, we do not have deferred revenue related to our agreement with AstraZeneca.

In general, other than as described above and in this paragraph, AstraZeneca has full responsibility for all research, development and commercialization costs under our license agreement. As part of its approval of MOVANTIK^®, the FDA required AstraZeneca to perform a post-marketing, observational epidemiological study comparing MOVANTIK^® to other treatments of OIC in patients with chronic, non-cancer pain. As a result, the royalty rate payable to us from net sales of MOVANTIK^® in the U.S. by AstraZeneca will be reduced by up to two percentage points to fund 33% of the external costs incurred by AstraZeneca to fund such post approval study, subject to a $35.0 million aggregate cap. Any costs incurred by AstraZeneca can only be recovered by the reduction of the royalty paid to us. In no case can amounts be recovered by the reduction of a contingent payment due from AstraZeneca to us or through a payment from us to AstraZeneca.

Daiichi Sankyo Europe GmbH: ONZEALD^TM (etirinotecan pegol), also referred to as NKTR-102

Effective May 30, 2016, we entered into a collaboration and license agreement with Daiichi Sankyo Europe GmbH, a German limited liability company (Daiichi), under which we granted Daiichi exclusive commercialization rights in the European Economic Area, Switzerland, and Turkey (collectively, the European Territory) to our proprietary product candidate ONZEALD^TM (etirinotecan pegol), which is also known as NKTR-102, a long-acting topoisomerase I inhibitor in clinical development for the treatment of adult patients with advanced breast cancer who have brain metastases (BCBM). Nektar retains all rights to ONZEALD^TM in all countries outside the European Territory including the United States.

Under the terms of the agreement and in consideration for the exclusive commercialization rights in the European Territory, Daiichi paid us a $20.0 million up-front payment in August 2016 and we will be eligible to receive up to an aggregate of $60.0 million in regulatory and commercial milestones, including a $10.0 million payment upon the first commercial sale of ONZEALD^TM following conditional marketing approval by the European Commission (EC), a $25.0 million payment upon the first commercial sale following final marketing authorization approval of ONZEALD^TM by the EC, and a $25.0 million sales milestone upon Daiichi’s first achievement of a certain specified annual net sales target. We are also eligible to receive a 20% royalty on net sales of ONZEALD^TM by Daiichi in all countries in the European Territory except for net sales in Turkey where Nektar is eligible to receive a 15% royalty. The parties will enter into a supply agreement whereby we will be responsible for supplying Daiichi with its requirements for ONZEALD^TM on a fully burdened reimbursed cost basis. Daiichi will be responsible for all commercialization activities for ONZEALD^TM in the European Territory and will bear all associated costs. In addition, we are responsible for funding and conducting a Phase 3 confirmatory trial in patients with BCBM which we call the ATTAIN study, which was initiated in the fourth quarter of 2016.

Daiichi may terminate the agreement in the event that the EC does not grant conditional marketing approval for ONZEALD^TM based on existing clinical data for ONZEALD^TM or the conditional marketing approval for ONZEALD^TM is not granted prior to a pre-specified future date (Daiichi Pre-Conditional Approval Termination). We may terminate the Agreement in the event that the EC requires changes in the ATTAIN study that materially increase the costs of such trial and Daiichi elects not to reimburse us for such incremental costs (Nektar Pre-Conditional Approval Termination). In the event of a Daiichi Pre-Conditional Approval Termination or a Nektar Pre-Conditional Approval Termination, we would be obligated to pay Daiichi a $12.5 million termination payment. Following conditional marketing approval of ONZEALD^TM by the EC, we would no longer have such termination payment obligation. Each party has certain other termination rights based on the safety or efficacy findings including the outcome of the ATTAIN study and any material uncured breaches of the Agreement. The $12.5 million contingent termination payment from us to Daiichi is recorded in our liability related to refundable upfront payment balance in our Consolidated Balance Sheet at December 31, 2016.

We identified our grant of the exclusive license to Daiichi on May 30, 2016 and our ongoing clinical and regulatory development service obligations as the significant, non-contingent deliverables under the agreement and determined that each represents a separate unit of accounting. We made our best estimate of the selling price for the license grant based on a discounted cash flow analysis of projected ONZEALD^TM sales and estimated the selling price for the development services based on our experience with the costs of similar clinical studies and regulatory activities. Based on these estimates, we allocated the $7.5 million non-refundable portion of the $20.0 million upfront payment from Daiichi to these items based on their relative selling prices. As a result, we recognized $3.7 million of revenue in 2016 from this arrangement, primarily related to the delivery of the license. As of December 31, 2016, we have deferred revenue of approximately $3.8 million related to our development service obligations under this agreement, which we expect to recognize through May 2021, the estimated end of our development obligations. If and when the remaining $12.5 million portion of the upfront payment becomes non-refundable, we expect to allocate this amount between the license and development service obligation consistent with the estimated selling prices of these deliverables. The license related amount will be recognized immediately and the development service related amount will be recorded as deferred revenue and recognized ratably over the remaining obligation period.

We determined that the milestones noted above payable to us by Daiichi upon the first commercial sale of ONZEALD^TM following conditional marketing approval and following final marketing authorization approval of ONZEALD^TM by the EC are substantive milestones that will be recognized if and when achieved. In addition, we determined that the sales milestone due to us upon Daiichi’s first achievement of a certain specified annual net sales target should be considered a contingent payment and will be recognized if and when achieved.

Baxalta Incorporated: Hemophilia

We are a party to an exclusive research, development, license and manufacturing and supply agreement with Baxalta Incorporated (Baxalta), a subsidiary of Shire Plc, entered into in September 2005 to develop products designed to improve therapies for Hemophilia A patients using our PEGylation technology. Under the terms of the agreement, we are entitled to research and development funding and are responsible for supplying Baxalta with its requirements for our proprietary materials. Baxalta is responsible for all clinical development, regulatory, and commercialization expenses. The agreement is terminable by the parties under customary conditions.

This Hemophilia A program includes ADYNOVATE^®, which was approved by the FDA in November 2015 for use in adults and adolescents, aged 12 years and older, who have Hemophilia A, and is now marketed in the U.S. As a result of the FDA’s approval, we earned a $10.0 million development milestone in November 2015, which was received in January 2016. In September 2014, as a result of Baxalta’s Phase 3 clinical trial results, we earned development milestones totaling $8.0 million. In addition, under the terms of this agreement, we are entitled to a $10.0 million development milestone due upon marketing authorization in the EU, as well as sales milestones upon achievement of annual sales targets and royalties based on annual worldwide net sales of products resulting from this agreement. As of December 31, 2016, we do not have deferred revenue related to this agreement.

Roche: PEGASYS^® and MIRCERA^®

In February 2012, we entered into a toll-manufacturing agreement with Roche under which we agreed to manufacture the proprietary PEGylation material used by Roche to produce MIRCERA^®. Roche entered into the toll-manufacturing agreement with the objective of establishing us as a secondary back-up supply source on a non-exclusive basis. Under the terms of our toll-manufacturing agreement, Roche paid us an upfront payment of $5.0 million and an additional $22.0 million in performance-based milestone payments upon our achievement of certain manufacturing readiness, validation and production milestones, including the delivery of specified quantities of PEGylation materials, all of which were completed as of January 2013. In addition, in 2013, we delivered additional quantities of PEGylation materials used by Roche to produce PEGASYS^® and MIRCERA^® for total consideration of $18.6 million. As of December 31, 2016, we no longer have any continuing manufacturing or supply obligations under this MIRCERA^®agreement and, therefore, have no deferred revenue related to this agreement.

In February 1997, we entered into a license, manufacturing and supply agreement with Roche, under which we granted Roche a worldwide, exclusive license to certain intellectual property related to our proprietary PEGylation materials used in the manufacture and commercialization of PEGASYS^®. Our performance obligations under this PEGASYS^® agreement ended on December 31, 2015.

Amgen, Inc.: Neulasta^®

In October 2010, we amended and restated an existing supply and license agreement by entering into a supply, dedicated suite and manufacturing guarantee agreement (the amended and restated agreement) and a license agreement with Amgen Inc. and Amgen Manufacturing, Limited (together referred to as Amgen). Under the terms of the amended and restated agreement, we guarantee the manufacture and supply of our proprietary PEGylation materials (Polymer Materials) to Amgen in an existing manufacturing suite to be used exclusively for the manufacture of Polymer Materials for Amgen (the Manufacturing Suite) in our manufacturing facility in Huntsville, Alabama (the Facility). This supply arrangement is on a non-exclusive basis (other than the use of the Manufacturing Suite and certain equipment) whereby we are free to manufacture and supply the Polymer Materials to any other third party and Amgen is free to procure the Polymer Materials from any other third party. Under the terms of the amended and restated agreement, we received a $50.0 million payment in the fourth quarter of 2010 in return for our guaranteeing the supply of certain quantities of Polymer Materials to Amgen including without limitation the Additional Rights described below and manufacturing fees that are calculated based on fixed and variable components applicable to the Polymer Materials ordered by Amgen and delivered by us. Amgen has no minimum purchase commitments. If quantities of the Polymer Materials ordered by Amgen exceed specified quantities, significant additional payments become payable to us in return for our guaranteeing the supply of additional quantities of the Polymer Materials.

The term of the amended and restated agreement ends on October 29, 2020. In the event we become subject to a bankruptcy or insolvency proceeding, we cease to own or control the Facility, we fail to manufacture and supply or certain other events, Amgen or its designated third party will have the right to elect, among certain other options, to take title to the dedicated equipment and access the Facility to operate the Manufacturing Suite solely for the purpose of manufacturing the Polymer Materials. Amgen may terminate the amended and restated agreement for convenience or due to an uncured material default by us.

As of December 31, 2016, we have deferred revenue of approximately $19.2 million related to this agreement, which we expect to recognize through October 2020, the estimated end of our obligations under this agreement.

Bayer Healthcare LLC: BAY41-6551 (Amikacin Inhale)

In August 2007, we entered into a co-development, license and co-promotion agreement with Bayer Healthcare LLC (Bayer) to develop a specially-formulated inhaled Amikacin. We are responsible for development and manufacturing and supply of our proprietary nebulizer device included in the Amikacin product. Bayer is responsible for most future clinical development and commercialization costs, all activities to support worldwide regulatory filings, approvals and related activities, further development of Amikacin Inhale and final product packaging and distribution. In April 2013, Bayer initiated a Phase 3 clinical trial in the treatment of intubated and mechanically ventilated patients with Gram-negative pneumonia. As of December 31, 2016, we have received an upfront payment of $40.0 million (which was paid to us in 2007) and milestone payments totaling $30.0 million (the last of which was paid to us in 2013). In addition, in June 2013, we made a $10.0 million payment to Bayer for the reimbursement of some of its costs of the Phase 3 clinical trial.

We are entitled to receive a total of up to an additional $50.0 million of development milestones upon achievement of certain development objectives, including $25.0 million related to a successful regulatory approval filing, as well as sales milestones upon achievement of annual sales targets and royalties based on annual worldwide net sales of Amikacin Inhale. As of December 31, 2016, we have deferred revenue of approximately $17.9 million related to this agreement, which we expect to recognize through June 2029, the estimated end of our obligations under this agreement.

Ophthotech Corporation: Fovista^®

We are a party to an agreement with Ophthotech Corporation (Ophthotech), dated September 30, 2006, under which Ophthotech received a worldwide, exclusive license to certain of our proprietary PEGylation technology to develop, manufacture and sell Fovista®. Under the terms of our agreement, we are the exclusive supplier of all of Ophthotech’s clinical and commercial requirements for our proprietary PEGylation reagent used in Fovista^®. On May 19, 2014, Ophthotech entered into a Licensing and Commercialization Agreement with Novartis Pharma AG for Fovista^®. Under our agreement with Ophthotech, in June 2014, we received a $19.8 million payment in connection with this licensing agreement.

On December 12, 2016, Ophthotech announced that its two pivotal Phase 3 clinical trials investigating the superiority of Fovista^® therapy in combination with Lucentis^® therapy compared to Lucentis^® monotherapy for the treatment of wet AMD had failed to meet their pre-specified primary endpoints. A separate Phase 3 clinical trial evaluating Fovista^® in combination with Eylea^® or Avastin^® compared to Eylea^® or Avastin^® monotherapy for the treatment of wet AMD is fully enrolled and remains ongoing. As of December 31, 2016, our obligations under the Ophthotech agreement are ongoing. As of December 31, 2016, we have accounts receivable of $6.1 million, which was subsequently collected in January 2017, and deferred revenue of approximately $16.8 million related to this agreement, which we expect to recognize through March 2029, the estimated end of our obligations under our agreement with Ophthotech. Our estimated performance obligation period is subject to reassessment each quarter and could change significantly based on Ophthotech’s pending Phase 3 study results.

Based on successful clinical study outcomes, we are entitled to additional payments based upon Ophthotech’s potential achievement of certain regulatory milestones. If commercialized, we are also entitled to royalties on net sales of Fovista^® that vary based on sales levels as well as a sales milestone.

Bristol-Myers Squibb: NKTR-214

On September 21, 2016, we entered into a Clinical Trial Collaboration Agreement (BMS Agreement) with Bristol-Myers Squibb Company, a Delaware corporation (BMS), pursuant to which we and BMS will collaborate to conduct Phase 1/2 clinical trials evaluating our IL-2-based CD122-biased agonist, known as NKTR-214, and BMS’ human monoclonal antibody that binds PD-1, known as Opdivo^® (nivolumab), as a potential combination treatment regimen in five tumor types and eight potential indications, and such other clinical trials evaluating the combined therapy as may be mutually agreed upon by the parties (each, a “Combination Therapy Trial”).

We will act as the sponsor of each Combination Therapy Trial. Under the BMS Agreement, BMS will be responsible for 50% of all out-of-pocket costs reasonably incurred in connection with third party contract research organizations, laboratories, clinical sites and institutional review boards and we record cost reimbursement payments to us from BMS as a reduction to research and development expense. Each party will otherwise be responsible for its own internal costs, including internal personnel costs, incurred in connection with each Combination Therapy Trial. Nektar and BMS will use commercially reasonable efforts to manufacture and supply NKTR-214 and Opdivo^® (nivolumab), respectively, for each Combination Therapy Trial with each party bearing its own costs related thereto. The parties formed a joint development committee to oversee clinical trial design, regulatory strategy, and other activities necessary to conduct and support the Combination Therapy Trials.

Ownership of, and global commercial rights to, NKTR-214 remain solely with us under the BMS Agreement. If we wish to license the right to commercialize NKTR-214 in one of certain major market territories prior to September 30, 2018 (Exclusivity Expiration Date), we must first negotiate with BMS, for a period of three months (Negotiation Period), to grant an exclusive license to develop and commercialize NKTR-214 in any of these major market territories. If we do not reach an agreement with BMS for an exclusive license within the Negotiation Period, we will be free to license any right to NKTR-214 to other parties in any territory worldwide except that in the event that we receive a license offer from a third party during a period of 90 calendar days after the end of the Negotiation Period, we will provide BMS ten business days to match the terms of such third-party offer. After the Exclusivity Expiration Date, we are free to license NKTR-214 without any further obligation to BMS. Each party grants to the other party a non-exclusive, worldwide (subject to certain exceptions in the case of the license granted by BMS), non-transferable and royalty-free research and development license to such licensing party’s patent rights, technology and regulatory documentation to use its compound solely to the extent necessary to discharge its obligations under the BMS Agreement with respect to the conduct of the Combination Therapy Trials.

Other

In addition, as of December 31, 2016, we have a number of other collaboration agreements, including with our collaboration partner UCB, under which we are entitled to up to a total of $45.5 million of development milestones upon achievement of certain development objectives, as well as sales milestones upon achievement of annual sales targets and royalties based on net sales of commercialized products, if any. However, given the current phase of development of the potential products under these collaboration agreements, we cannot estimate the probability or timing of achieving these milestones. As of December 31, 2016, we have deferred revenue of approximately $8.6 million related to these other collaboration agreements, which we expect to recognize through 2020, the estimated end of our obligations under those agreements.
