Astellas Pharma Inc. and Drais Pharmaceuticals, Inc. today announced that they have entered into a third partnership in the past year to develop and commercialize an Astellas compound. Under the terms of the agreement, Astellas will license ASP7035, of which a phase I study has been completed and is a phase IIa-ready, vasopressin V2 receptor selective agonist for the treatment of nocturia, to Tacurion Pharma, Inc., a virtual company that will be operated by the Drais executive team. The partnership is similar to two prior Astellas and Drais agreements, to advance ASP3291 and ASP7147 through Telsar Pharma, Inc. and Seldar Pharma, Inc., respectively -- both also virtual companies. As with Telsar and Seldar, Tacurion will be operated by Drais, which has substantial clinical development experience.
Tacurion, Telsar and Seldar all share the same investors: InterWest Partners and Sutter Hill Ventures (two U.S. venture capital firms that are also the lead investors in Drais) plus Astellas Venture Management LLC (the corporate venture capital arm of Astellas). The three groups will invest a total of $15 million into Tacurion. These funds will provide a runway to further the development of ASP7035, with Drais serving as the exclusive provider of development services.
This partnership is reflective of Astellas' 'Multi-Track R&D' approach, in which the company moves select promising compounds forward without any disruption in the development process. The approach allows Astellas to optimize costs and control risks while accessing outside capital and expertise.
The partnerships are a long-term enterprise that Astellas and Drais may expand by moving additional Astellas compounds into virtual companies for development by Drais. Working with virtual companies is a straightforward solution that allows the investors to target their investment to one compound. Virtual companies also provide a simpler structure for any future sale of the compound.
The participants in the partnership have all worked together successfully in the past. The Drais executive team was previously the senior management of Yamanouchi R&D (a precursor company to Astellas) in Paramus, NJ. Later they served as the executive team of AkaRx, acquired by Eisai/MGI for $300 million in 2010. Dr. Arnold Oronsky, general partner at InterWest, and Dr. Jeff Bird, managing director at Sutter Hill Ventures, are both board members and investors in Drais; they previously held the same positions at AkaRx. Astellas Venture Management was also an investor in AkaRx.
Under the terms of the agreement, Tacurion has an exclusive worldwide license to develop and commercialize ASP7035. Tacurion will be responsible for all development, manufacturing and commercialization activities and their associated costs. Astellas is entitled to receive a milestone payment and royalties on future sales of ASP7035. Astellas also has a onetime option (but not an obligation) to acquire Tacurion upon the success of a proof of concept study. The company expects to initiate the phase II proof-of-concept study in the third quarter of 2013.
