Collaborative Licensing And Other Arrangements [Abstract] |
Collaborative, Licensing and Other Arrangements | 4. Collaborative, Licensing and Other Arrangements Collaborative and Other Agreements Novartis – Gevokizumab and IL-1 Beta On August 24, 2017, the Company and Novartis Pharma AG (“Novartis”) entered into a license agreement (the “XOMA-052 License Agreement”) under which the Company granted to Novartis an exclusive, worldwide, royalty-bearing license to gevokizumab, a novel anti-Interleukin-1 (“IL-1”) beta allosteric monoclonal antibody (the “Antibody”) and related know-how and patents (altogether, the “XOMA IP”). Under the terms of the XOMA-052 License Agreement, Novartis will be solely responsible for the development and commercialization of the Antibody and products containing the Antibody. The Company completed the transfer of the required proprietary know-how, process, materials and inventory relating to the XOMA IP to Novartis as of December 31, 2017. On August 24, 2017, pursuant to a separate agreement (the “IL-1 Target License Agreement”), the Company granted to Novartis non-exclusive licenses to its intellectual property covering the use of IL-1 beta targeting antibodies in the treatment and prevention of cardiovascular disease and other diseases and conditions, and an option to obtain an exclusive license (the “Exclusivity Option”) to such intellectual property for the treatment and prevention of cardiovascular disease. The Company also granted Novartis the right of first negotiation with respect to certain transactions relating to the licensed intellectual property. Under the XOMA-052 License Agreement, the Company received total consideration of $30.0 million for the license and rights granted to Novartis. Of the total consideration, $15.7 million was paid in cash and $14.3 million (equal to €12.0 million) was paid by Novartis Institutes for BioMedical Research, Inc. (“NIBR”), on behalf of the Company, to settle the Company’s outstanding debt with Les Laboratories Servier (the “Servier Loan”). In addition, NIBR extended the maturity date on the Company’s debt to Novartis (see Note 8). The Company also received $5.0 million cash related to the sale of 539,131 shares of the Company’s common stock, at a purchase price of $9.2742 per share. The fair market value of the common stock issued to Novartis was $4.8 million, based on the closing stock price of $8.93 per share on August 24, 2017, resulting in a $0.2 million premium paid to the Company (see Note 12). Based on the achievement of pre-specified criteria, the Company is eligible to receive up to $438.0 million in development, regulatory and commercial milestones. The Company is also eligible to receive royalties on sales of licensed products, which are tiered based on sales levels and range from the high single digits to mid-teens. Under the IL-1 Target License Agreement, the Company received an upfront cash payment of $10.0 million and is eligible to receive low single-digit royalties on canakinumab sales in cardiovascular indications. Should Novartis exercise the Exclusivity Option, the royalties on canakinumab sales will increase to the mid-single digits. The XOMA-052 License Agreement and IL-1 Target License Agreement were accounted for as one arrangement because they were entered into at the same time in contemplation of each other. The Company concluded that there are multiple deliverables under the combined arrangement which consisted of (i) the licenses to IL-1 beta targeting antibodies, (ii) the license to gevokizumab antibody and (iii) the transfer of know-how, process, materials and inventory related the gevokizumab antibody. The Company concluded that the license to the gevokizumab antibody and the related transfer of know-how process, materials and inventory each do not have stand-alone value. Accordingly, the Company combined these two deliverables into a single unit of accounting. The Company determined that the Exclusivity Option is a substantive option and not priced at a significant and incremental discount. Therefore, the Company concluded that the Exclusivity Option is not a deliverable. The agreements were evaluated pursuant to the provisions of the multiple-element arrangement guidance in determining how to recognize the revenue associated with each unit of account. The total arrangement consideration received from Novartis is $40.2 million and consists of the $25.7 million upfront cash payments, the $14.3 million Servier Loan payoff and the $0.2 million premium on the sale of the common stock. The total arrangement consideration was allocated to each unit of account based on their relative selling prices. Revenue was recognized as the revenue recognition criteria were met for each identified unit of account. During the year ended December 31, 2017, the Company recognized revenue of $31.9 million related to the licenses to IL-1 beta targeting antibodies and the consideration allocated to the gevokizumab antibody of $8.3 million upon completing the transfer of certain proprietary know-how, process, materials and inventory relating to the XOMA IP. The Company determined that future contingent payments that may be received related to development, regulatory and sales milestones under the XOMA-052 License Agreement are based on the performance of Novartis and do not meet the definition of substantive milestones under the accounting guidance. Accordingly, revenue for the achievement of these milestones will be recognized in the period when the milestone is achieved. As of December 31, 2017, the Company has not recognized any milestone payments under the XOMA-052 License Agreement. The Company expects to recognize royalty revenue in the period of sale of the related products, based on the underlying contract terms. No such amounts were recognized during the year ended December 31, 2017. Novartis – Anti-TGFβ Antibody On September 30, 2015, the Company and Novartis International Pharmaceutical Ltd. (“Novartis International”) entered into a license agreement (the “License Agreement”) under which the Company granted Novartis International 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 International 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. 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. The Company is also eligible to receive royalties on sales of licensed products, which are tiered based on sales levels and range from a mid-single digit percentage rate to up to a low double-digit percentage rate. Novartis International’s obligation to pay royalties with respect to a particular product and country will continue for the longer of the date of expiration of the last valid patent claim covering the product in that country, or ten years from the date of the first commercial sale of the product in that country. The License Agreement contains customary termination rights relating to material breach by either party. Novartis International also has a unilateral right to terminate the License Agreement on an antibody-by-antibody and country-by-country basis or in its entirety on one hundred eighty days’ notice. The Company identified the following performance deliverables under the License Agreement: (i) the license, (ii) regulatory services to be delivered within 90 days from the Effective Date and (iii) transfer of materials, process and know-how, also to be delivered within 90 days from the Effective Date. The Company considered the provisions of the multiple-element arrangement guidance in determining how to recognize the revenue associated with these deliverables. The Company determined that none of the deliverables have standalone value and therefore has accounted for them as a single unit of account. The Company recognized the entire upfront payment as revenue in the consolidated statement of comprehensive income (loss) in 2015 as it had completed its performance obligations as of December 31, 2015. During the year ended December 31, 2017, Novartis International 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 consolidated statement of comprehensive income (loss). As of December 31, 2017, the Company is eligible to receive up to a total of $470.0 million in development, regulatory and commercial milestones. In connection with the execution of the License Agreement, XOMA and Novartis Vaccines Diagnostics, Inc. (“NVDI”) executed an amendment to their Amended and Restated Research, Development and Commercialization Agreement dated July 1, 2008, as amended, relating to anti-CD40 antibodies (the “Collaboration Agreement Amendment”). Pursuant to the Collaboration Agreement Amendment, the parties agreed to reduce the royalty rates and period that XOMA is eligible to receive on sales of NVDI’s clinical stage anti-CD40 antibodies. These royalties are tiered based on sales levels and now range from a mid-single digit percentage rate to up to a low double-digit percentage rate and royalties are payable until the later of any licensed patent covering each product or ten years from the launch of each product. All other terms of the Amended and Restated Research, Development and Commercialization Agreement remained unchanged (see Note 8). Rezolute On December 6, 2017, the Company entered into a license agreement with Rezolute, Inc. (formerly AntriaBio, Inc.) (“Rezolute”) pursuant to which the Company granted an exclusive global license to Rezolute to develop and commercialize X358 (now “RZ358”) for all indications. The Company and Rezolute also entered into a common stock purchase agreement. Under the terms of the license agreement, Rezolute is responsible for all development, regulatory, manufacturing and commercialization activities associated with RZ358 and is required to make certain clinical, regulatory and commercial milestone payments to the Company of up to $232.0 million in the aggregate based on the achievement of pre-specified criteria. Under the license agreement, the Company is also eligible to receive royalties ranging from the high single digits to the mid-teens based upon annual net sales of any commercial product incorporating RZ358. Rezolute is obligated to take customary steps to advance RZ358, including using diligent efforts to commence the next clinical study for RZ358 by a certain deadline and to meet certain spending requirements on an annual basis for the program until a marketing approval application for RZ358 is accepted by the FDA. Rezolute’s obligation to pay royalties with respect to a particular RZ358 product and country will continue for the longer of the date of expiration of the last valid patent claim covering the product in that country, or twelve years from the date of the first commercial sale of the product in that country. Rezolute has an option through June 1, 2019 to obtain an exclusive license for their choice of one of the Company’s preclinical monoclonal antibody fragments, including X129, in exchange for a $1.0 million upfront option fee and additional clinical, regulatory and commercial milestone payments to the Company of up to $237.0 million in the aggregate based on the achievement of pre-specified criteria as well as royalties ranging from the high single digits to the mid-teens based on annual net sales. Pursuant to the license agreement and common stock purchase agreement, the Company is eligible to receive $6.0 million in cash and $12.0 million worth of Rezolute’s common stock contingent on the completion of its financing activities. Further, in the event that Rezolute does not complete a financing that raises at least $20.0 million in aggregate gross proceeds (“Qualified Financing”) by March 31, 2019, the Company will receive an additional number of shares of Rezolute’s common stock equal to $7.0 million divided by the weighted average of the closing bid and ask prices or the average closing prices of Rezolute’s common stock on the ten-day trading period prior to March 31, 2019. Finally, in the event that Rezolute is unable to complete a Qualified Financing by March 31, 2020, the Company is eligible to receive $15.0 million in cash in order to maintain the license. Under the common stock purchase agreement, Rezolute granted the Company the right and option to sell the greater of (i) 5,000,000 shares of common stock or (ii) one third of the aggregate shares held by the Company upon failure by Rezolute to list its shares of its common stock on the Nasdaq Stock Market or a similar national exchange on or prior to December 31, 2018. In addition, under the terms of the license agreement, the Company is eligible to receive a low single digit royalty on sales of Rezolute’s other products from its current programs. Rezolute’s obligation to pay royalties with respect to a particular Rezolute product and country will continue for the longer of twelve years from the date of the first commercial sale of the product in that country or for so long as Rezolute or its licensee is selling such product in such country, provided that such royalty will terminate upon the termination of the licensee’s obligation to make payments to Rezolute based on sales of such product in such country. The license agreement contains customary termination rights relating to material breach by either party. Rezolute also has a unilateral right to terminate the license agreement in its entirety on ninety days’ notice at any time. The Company has the right to terminate the license agreement if Rezolute challenges the licensed patents. The Company concluded that there are multiple deliverables under the license agreement which consist of (i) the license to RZ358, (ii) the transfer of RZ358 materials and product data/filing, and (iii) the transfer of process and know-how related to RZ358. The Company concluded that the license to RZ358 and the related transfer of materials, product data/filing, process and know-how each do not have stand-alone value. Accordingly, the Company combined these three deliverables into a single unit of accounting. The Company determined that the option to obtain an exclusive license for one of the Company’s preclinical monoclonal antibody fragments, including X129, is a substantive option and not priced at a significant and incremental discount. Therefore, the Company concluded that the option is not a deliverable. Under the agreements, no consideration was exchanged upon execution of the arrangement. Rezolute agreed to issue shares of its common stock and pay cash to the Company upon the occurrence of Rezolute’s financing activities and related timing of those activities. At December 31, 2017, Rezolute has not completed any of its financing activities and therefore, the Company has not recognized any revenue under the arrangement. 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, which provided for a non-refundable upfront payment of $15.0 million that was received by the Company in January 2011. In addition, the Company received a loan of €15.0 million, which was fully funded in January 2011, with the proceeds converting to $19.5 million at the date of funding (see Note 8). 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. XOMA retained development and commercialization rights in the United States and Japan for all indications other than cardiovascular disease and diabetes. On September 28, 2015, Servier notified XOMA of its intention to terminate the Collaboration Agreement, as amended, 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 is 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. The Company and Servier completed the final reconciliation of cost sharing under the collaboration and all related adjustments are reflected in the consolidated statement of comprehensive income (loss) for the year ended December 31, 2016. For the years ended December 31, 2016 and 2015, the Company recorded revenue of $0.6 million and $1.2 million, respectively, from this Collaboration Agreement. NIAID In September 2008, the Company announced that it had been awarded a $64.8 million multiple-year contract funded with federal funds from NIAID (Contract No. HHSN272200800028C), to continue the development of anti-botulinum antibody product candidates. The contract work was being performed on a cost plus fixed fee basis over a three-year period. The Company recognizes revenue under the arrangement as the services are performed on a proportional performance basis. Consistent with the Company’s other contracts with the U.S. government, invoices are provisional until finalized. The Company operated under provisional rates from 2010 through 2014, subject to adjustment based on actual rates upon agreement with the government. In 2014, upon completion of a NIAID review of hours and external expenses, XOMA agreed to exclude certain hours and external expenses resulting in a $1.8 million adjustment to decrease previously invoiced balances. The adjustment was offset by a $1.9 million deferred revenue balance that was recorded in 2012 as a result of a rate adjustment for the period 2007 to 2009. This adjustment reduced accounts receivable and deferred revenue by $1.8 million to reflect the final settlement of the 2008 to 2013 hours and external review. NIAID has deferred payment of the remaining $0.4 million in accounts receivable pending the final agreement on the ongoing 2010 to 2013 final rate submission. The remaining $0.1 million in deferred revenue in connection with the 2011 NIH rate audit would be recognized upon completion of negotiations with and approval by the NIH. The Company recognized revenue of $0.1 million and $0.2 million under this contract, for the years ended December 31, 2017 and 2015. There was no revenue recognized during the year ended December 31, 2016. As of December 31, 2017, the Company wrote off the $0.4 million receivable from NIAID as the likelihood of collection is remote. In October 2011, the Company announced that NIAID had awarded the Company a new contract under Contract No. HHSN272201100031C (“NIAID 4”) 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 recognized revenue under the arrangement as the services were performed on a proportional performance basis. The Company recognized revenue of $1.1 million and $4.9 million under this contract, for the years ended December 31, 2016 and 2015, respectively. There was no revenue recognized during the year ended December 31, 2017. In March 2016, the Company effected a novation of the NIAID 4 to Ology Bioservices. The novation was effected upon obtaining government approval to transfer the contract to Ology Bioservices pursuant to the asset purchase agreement executed in November 2015 (see Note 6). Pfizer In August 2007, the Company entered into a license agreement (the “2007 Agreement”) with Pfizer Inc. (“Pfizer”) for non-exclusive, worldwide rights for XOMA’s patented bacterial cell expression technology for research, development and manufacturing of antibody products. From 2011 through 2015, the Company received milestone payments aggregating $4.2 million. On December 3, 2015, the Company and Pfizer entered into a settlement and amended license agreement pursuant to which XOMA granted Pfizer a fully-paid, royalty-free, worldwide, irrevocable, non-exclusive license right to XOMA’s patented bacterial cell expression technology for phage display and other research, development and manufacturing of antibody products. Under the amended license agreement, the Company received a cash payment of $3.8 million in full satisfaction of all obligations to XOMA under the 2007 Agreement, including but not limited to potential milestone, royalty and other fees under the 2007 Agreement. The Company recognized the entire payment from Pfizer as revenue upon delivery of the license in 2015. In August 2005, the Company entered into a license agreement with Wyeth (subsequently acquired by Pfizer) for non-exclusive, worldwide rights for certain of XOMA’s patented bacterial cell expression technology for vaccine manufacturing. Under the terms of this agreement, the Company received a milestone payment in November 2012 relating to TRUMENBA®, a meningococcal group B vaccine marketed by Pfizer. The Company’s right to royalties expires on a country-by-country basis upon the expiration of the last-to-expire licensed patent. The Company recognized zero and $0.4 million of royalties earned from the sales of TRUMENBA during the years ended December 31, 2017 and 2016. The royalties on sales of TRUMENBA for the years ended December 31, 2015 were not material. As discussed below under Sale of Future Revenue Streams, the Company sold its right to receive all future milestones and royalties on future sales of products to HCRP in connection with the Royalty Interest Acquisition Agreement entered into in December 2016. Novo Nordisk On December 1, 2015, the Company and Novo Nordisk A/S (“Novo Nordisk”) entered into a license agreement under which XOMA granted to Novo Nordisk an exclusive, world-wide, royalty-bearing license to XOMA’s XMetA program of allosteric monoclonal antibodies that positively modulate the insulin receptor (the “XMetA Program”), subject to XOMA’s retained commercialization rights for rare disease indications. Novo Nordisk had an option to add these retained rights to its license upon payment of an option fee. Novo Nordisk obtained worldwide rights to the XMetA Program and was solely responsible at its expense for the development and commercialization of antibodies and products containing antibodies arising from the XMetA Program, subject to the Company’s retained rights described above. The Company had transferred certain proprietary know-how and materials relating to the XMetA Program to Novo Nordisk. Under the agreement, the Company received a $5.0 million, non-creditable, non-refundable, upfront payment. Based on the achievement of pre-specified criteria, the Company was eligible to receive up to $290.0 million in development, regulatory and commercial milestones. The Company was also eligible to receive royalties on sales of licensed products, which would be tiered based on sales levels and range from a mid-single digit percentage rate to up to a high single digit percentage rate. Novo Nordisk’s obligation to pay development and commercialization milestones would continue for so long as Novo Nordisk was developing or selling products under the agreement, subject to the maximum milestone payment amounts set forth above. Novo Nordisk’s obligation to pay royalties with respect to a particular product and country would continue for the longer of the date of expiration of the last valid patent claim covering the product in that country, or ten years from the date of the first commercial sale of the product in that country. The Company identified the following performance deliverables under the agreement: (i) the license, and (ii) the transfer of technology and know-how to be delivered within 60 days from December 1, 2015. The Company delivered the majority of the technology and know-how to Novo Nordisk as of December 31, 2015 and determined that any remaining items are perfunctory to the arrangement. Accordingly, the Company recognized the entire $5.0 million upfront fee as revenue in 2015. On April 20, 2017, the Company received notice from Novo Nordisk regarding the termination of the license agreement due to strategic and business reasons. The termination of the license agreement became effective on July 20, 2017. Sale of Future Revenue Streams On December 21, 2016, the Company entered into two Royalty Interest Acquisition Agreements (together, the “Acquisition Agreements”) with 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 (now Pfizer, Inc.) 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. Based on estimated sales for 2017, the 2017 sales milestone was not achieved. The Company remains eligible to receive up to $3.0 million if specified net sales milestones are achieved in 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 a litigation or 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 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 proceeds received from HCRP to the payments expected to be made to HCRP over the term of the Acquisition Agreements, and then applying that ratio to the period’s cash payment. The Company recognized $0.3 million as contract and other revenue under these arrangements during the year ended December 31, 2017. As of December 31, 2017, the current and non-current portion of the remaining deferred revenue was $0.6 million and $17.1 million, respectively. As of December 31, 2016, the Company classified the $18.0 million as non-current deferred revenue. As of December 31, 2017, the net sales milestone related to 2017 was not met and therefore, the Company did not recognize any revenue for milestones under the first Acquisition Agreement.
