Collaboration and License Agreements [Abstract] |
Collaborative Arrangement Disclosure | Collaboration and License Agreements Lexicon has derived substantially all of its revenues from drug discovery and development collaborations, target validation collaborations for the development and, in some cases, analysis of the physiological effects of genes altered in knockout mice, government grants and contracts, technology licenses, subscriptions to its databases and compound library sales. Sanofi. In November 2015, Lexicon entered into a Collaboration and License Agreement (the “Sanofi Agreement”) with Sanofi for the worldwide development of Lexicon’s diabetes drug candidate sotagliflozin. Under the Sanofi Agreement, Lexicon granted Sanofi an exclusive, worldwide, royalty-bearing right and license under its patent rights and know-how to develop, manufacture and commercialize sotagliflozin. Subject to specified exceptions, neither party may (a) perform clinical development activities relating to any other compound which inhibits sodium-glucose cotransporters type 1 or type 2 or (b) commercialize any such compounds in the United States, countries of the European Union and certain other specified countries, in each case during the royalty terms applicable in such countries. Among the specified exceptions is a right Lexicon retained to pursue the development of its LX2761 drug candidate, with respect to which Lexicon granted Sanofi certain rights of first negotiation specified in the Sanofi Agreement. Under the Sanofi Agreement, Sanofi paid Lexicon an upfront payment of $300 million. In addition, Lexicon is eligible to receive from Sanofi (a) up to an aggregate of $110 million upon the achievement of two development milestones relating to the achievement of positive results in certain Phase 3 clinical trials in type 2 diabetes patients, with such aggregate amount being predominantly allocated to one of the two development milestones, (b) up to an aggregate of $220 million upon the achievement of four regulatory milestones relating to the first commercial sale following regulatory approval of sotagliflozin for type 1 and type 2 diabetes, respectively, in each of the United States and Europe, of which two milestones representing the substantial majority of such aggregate amount relate to type 2 diabetes and the remaining two milestones relate to type 1 diabetes, (c) $100 million upon the achievement of a milestone based on the results of an outcomes study in type 2 diabetes patients the completion of which would likely occur after initial regulatory approval, and (d) up to an aggregate of $990 million upon the achievement of six commercial milestones that will be achieved upon reaching specified levels of sales. The Company believes that each of the development and regulatory milestones under the Sanofi Agreement is substantive. Due to the uncertainty surrounding the achievement of the future development and regulatory milestones, these payments will not be recognized as revenue unless and until they are earned, as the Company is not able to reasonably predict if and when the milestones will be achieved. Commercial milestones, which are not encompassed within the definition of milestones under generally accepted accounting principles, will be accounted for as royalties and recorded as revenue upon achievement of the milestone, assuming all other revenue recognition criteria were met. Lexicon is also entitled to tiered, escalating royalties ranging from low double digit percentages to forty percent of net sales of sotagliflozin, based on indication and territory, with royalties for the higher band of such range attributable to net sales for type 1 diabetes in the United States, and subject in each case to customary royalty reduction provisions. Royalties payable with respect to net sales of sotagliflozin for type 1 diabetes in the United States will also be reduced in the event Lexicon does not exercise its co-promotion option described below. Lexicon will continue to be responsible for all clinical development activities relating to type 1 diabetes and will retain an exclusive option to co-promote and have a significant role, in collaboration with Sanofi, in the commercialization of sotagliflozin for the treatment of type 1 diabetes in the United States. If Lexicon exercises its co-promotion option, Lexicon will fund forty percent of the commercialization costs relating to such co-promotion activities. Sanofi will be responsible for all clinical development and commercialization of sotagliflozin for the treatment of type 2 diabetes worldwide and will be solely responsible for the commercialization of sotagliflozin for the treatment of type 1 diabetes outside the United States. Lexicon will share in the funding of a portion of the planned type 2 diabetes development costs over the next three years, up to an aggregate of $100 million. Sanofi will book sales worldwide in all indications. The parties are responsible for using commercially reasonable efforts to perform their development and commercialization obligations pursuant to mutually approved development and commercialization plans. The parties’ activities under the Sanofi Agreement are governed by a joint steering committee and certain other governance committees which reflect equal or other appropriate representation from both parties. If the applicable governance committee is not able to make a decision by consensus and the parties are not able to resolve the issue through escalation to specified senior executive officers of the parties, then Sanofi will have final decision-making authority, subject to limitations specified in the Sanofi Agreement. The Sanofi Agreement will expire upon the expiration of all applicable royalty terms for all licensed products in all countries. The royalty term for each licensed product in each country is the period commencing on the effective date of the Sanofi Agreement and ending on the latest of expiration of specified patent coverage, expiration of specified regulatory exclusivity and 10 years following the first commercial sale in the applicable country. Either party may terminate the Sanofi Agreement in the event of an uncured material breach by the other party. Prior to completion of the core development activities for type 2 diabetes specified in the development plan, Sanofi may terminate the Sanofi Agreement on a country-by-country and licensed product-by-licensed product basis, in the event of (a) notification of a material safety issue relating to the licensed product or the class of sodium-glucose cotransporters type 1 or type 2 inhibitors resulting in a recommendation or requirement that Lexicon or Sanofi cease development, (b) failure to achieve positive results with respect to certain clinical trial results, (c) the occurrence of specified fundamental adverse events or (d) the exploitation of the licensed product infringing third party intellectual property rights in specified major markets and Sanofi is unable to obtain a license to such third party intellectual property rights. The Company considered the following deliverables with respect to the revenue recognition of the $300 million upfront payment: • The exclusive worldwide license granted to Sanofi to develop and commercialize sotagliflozin; • The development services Lexicon is performing for sotagliflozin relating to type 1 diabetes; and • The funding Lexicon will provide for development relating to type 2 diabetes. The Company determined that the license had stand-alone value because it is an exclusive license that gives Sanofi the right to develop and commercialize sotagliflozin or to sublicense its rights. In addition, sotagliflozin is currently in development and it is possible that Sanofi or another third party could conduct clinical trials without assistance from Lexicon. As a result, the Company considers the license and the development services under the Sanofi Agreement to be separate units of accounting. The Company recognized the portion of the consideration allocated to the license immediately because Lexicon delivered the license and earned the revenue at the inception of the arrangement. The Company is recognizing as revenue the amount allocated to the development services for type 1 diabetes and the obligation to provide funding for development services for type 2 diabetes over the period of time Lexicon performs services or provides funding, currently expected to be through 2020. The Company determined that the initial allocable arrangement consideration was the $300 million upfront payment because it was the only payment that was fixed and determinable at the inception of the arrangement. There was considerable uncertainty at the date of the agreement as to whether Lexicon would earn milestone payments or royalty payments. As such, the Company did not include those payments in the allocable consideration. The Company allocated the allocable consideration based on the relative best estimate of selling price of each unit of accounting. The Company estimated the selling price of the license deliverable by applying a probability-based income approach utilizing an appropriate discount rate. The significant inputs the Company used to determine the projected income of the license included: exercising the option to co-promote, estimated future product sales, estimated cost of goods sold, estimated operating expenses, income taxes, and an appropriate discount rate. The Company estimated the selling price of the development services for type 1 diabetes by using internal estimates of the cost to hire third parties to perform the services over the expected period to perform the development. The Company estimated the obligation to provide funding for type 2 diabetes by using internal estimates of the expected cash flows and timing for $100 million in funding. As a result of the allocation, the Company recognized $126.8 million of the $300 million upfront payment for the license in 2015. The Company is recognizing the $113.8 million allocated to the development services deliverable and the $59.4 million allocated to the funding deliverable over the estimated period of performance as the development and funding occurs. Revenue recognized under the Sanofi Agreement was $17.0 million and $12.0 million for the three months ended March 31, 2017 and 2016, respectively. Ipsen Pharma SAS. In October 2014, Lexicon entered into a License and Collaboration Agreement, which was subsequently amended in March 2015 (collectively, the “Ipsen Agreement”), with Ipsen Pharma SAS (“Ipsen”) for the development and commercialization of telotristat ethyl outside of the United States and Japan (the “Licensed Territory”). Under the Ipsen Agreement, Lexicon granted Ipsen an exclusive, royalty-bearing right and license under its patent rights and know-how to commercialize telotristat ethyl in the Licensed Territory. Ipsen is responsible for using diligent efforts to commercialize telotristat ethyl in the Licensed Territory pursuant to a mutually approved commercialization plan. Subject to certain exceptions, Lexicon will be responsible for conducting clinical trials required to obtain regulatory approval for telotristat ethyl for carcinoid syndrome in the European Union, including those contemplated by a mutually approved initial development plan, and will have the first right to conduct most other clinical trials of telotristat ethyl. Lexicon is responsible for the costs of all clinical trials contemplated by the initial development plan. The costs of additional clinical trials will be allocated between the parties based on the nature of such clinical trials. Under the Ipsen Agreement, Ipsen has paid Lexicon an aggregate of $30.9 million through March 31, 2017, consisting of $24.5 million in upfront payments and a $6.4 million milestone payment in August 2016 upon the acceptance of the filing submitted by Ipsen to the European Medicines Agency for telotristat ethyl as an adjunct to somatostatin analog therapy for the long-term treatment of carcinoid syndrome. In addition, Lexicon is eligible to receive from Ipsen (a) up to an aggregate of approximately $27 million upon the achievement of specified regulatory and commercial launch milestones and (b) up to an aggregate of €72 million upon the achievement of specified sales milestones. Due to the uncertainty surrounding the achievement of the future regulatory and sales milestones, these payments will not be recognized as revenue unless and until they are earned as the Company is not able to reasonably predict if and when the milestones will be achieved. Lexicon is also entitled to tiered, escalating royalties ranging from low twenties to mid-thirties percentages of net sales of telotristat ethyl in the Licensed Territory, subject to a credit for amounts previously paid to Lexicon by Ipsen for the manufacture and supply of such units of telotristat ethyl. Lexicon and Ipsen have entered into a commercial supply agreement pursuant to which Lexicon will supply Ipsen’s commercial requirements of telotristat ethyl, and Ipsen will pay an agreed upon transfer price for such commercial supply. The Company considered the following deliverables with respect to the revenue recognition of the $24.5 million upfront payments:
• | The exclusive license granted to Ipsen to develop and commercialize telotristat ethyl in the Licensed Territory;
•The development services Lexicon is performing for telotristat ethyl;
• | The obligation to participate in committees which govern the development of telotristat ethyl until commercialization; and
•The obligation to supply commercial supply of telotristat ethyl, under a commercial supply agreement. The Company determined that the license had stand-alone value because it is an exclusive license that gives Ipsen the right to develop and commercialize telotristat ethyl or to sublicense its rights. In addition, telotristat ethyl is currently in development and it is possible that Ipsen or another third party could conduct clinical trials without assistance from Lexicon. As a result, the Company considers the license and the development services under the Ipsen Agreement to be separate units of accounting. The Company recognized the portion of the consideration allocated to the license immediately because Lexicon delivered the license and earned the revenue at the inception of the arrangement. The Company is recognizing as revenue the amount allocated to the development services and the obligation to participate in committees over the period of time Lexicon performs services, currently expected to be through mid-2017. Due to the inherent uncertainty in obtaining regulatory approval, the applicability of the commercial supply agreement is outside the control of Lexicon and Ipsen. Accordingly, the Company has determined the commercial supply agreement is a contingent deliverable at the onset of the Ipsen Agreement. As a result, the Company has determined the commercial supply agreement does not meet the definition of a deliverable that needs to be accounted for at the inception of the arrangement. The Company has also determined that there is no significant and incremental discount related to the commercial supply agreement that should be accounted for at the inception of the arrangement. The Company determined that the initial allocable arrangement consideration was the $24.5 million upfront payments because they were the only payments that were fixed and determinable at the inception of the arrangement. There was considerable uncertainty at the date of the agreement as to whether Lexicon would earn milestone payments, royalty payments or payments for finished drug product. As such, the Company did not include those payments in the allocable consideration. The Company allocated the allocable consideration based on the relative best estimate of selling price of each unit of accounting. The Company estimated the selling price of the license deliverable by applying a probability-based income approach utilizing an appropriate discount rate. The significant inputs the Company used to determine the projected income of the license included: estimated future product sales, estimated cost of goods sold, estimated operating expenses, income taxes, and an appropriate discount rate. The Company estimated the selling price of the development services by using internal estimates of the cost to hire third parties to perform the services over the expected period to perform the development. The Company estimated the selling price of the obligation to participate in committees by using internal estimates of the number of internal hours and salary and benefits costs to perform these services. As a result of the allocation, the Company recognized $21.2 million of the $24.5 million upfront payments for the license in 2014, and an additional $1.4 million in 2015 upon entering into the amendment. The Company is recognizing the $1.7 million allocated to the development services deliverable over the estimated period of performance as development occurs, and is recognizing the $0.1 million allocated to the committee participation deliverable ratably over the estimated period of performance. Milestone payments that are contingent upon the achievement of a substantive milestone are recognized in their entirety in the period in which the milestone is achieved. Revenue recognized under the Ipsen Agreement was $0.5 million and $0.1 million for the three months ended March 31, 2017 and 2016, respectively.
