Item 8.01. Other Events.
On January 31, 2013, BioSante Pharmaceuticals, Inc. (BioSante) entered into an asset purchase agreement with Aduro BioTech, Inc., a clinical-stage immunotherapy company (Aduro), pursuant to which BioSante sold all of its assets related to its GVAX cancer vaccine portfolio in exchange for a $1.0 million up front cash payment plus the potential for future royalty, milestone and sublicense payments.
The asset purchase agreement is an extension of Aduros March 2011 license of BioSantes GVAX Pancreas cancer vaccine and BioSantes GVAX Prostate cancer vaccine solely for use in combination with Aduros proprietary vaccine platform based on Listeria monocytogenes. Aduro currently is evaluating the sequential administration of GVAX Pancreas and the Listeria-based CRS-207 in a Phase 2 trial in patients with metastatic pancreatic cancer (ClinicalTrials.gov Identifier NCT01417000) and announced on November 29, 2012 that enrollment has been completed.
Since BioSante acquired the GVAX cancer vaccine portfolio in October 2009 through its merger with Cell Genesys, Inc., BioSantes objective always has been to help facilitate further studies and commercialization in order to bring important cancer therapies to patients in need and to maximize the value of the GVAX cancer vaccine portfolio to the BioSante stockholders. BioSante believes that the sale transaction with Aduro is consistent with this objective, especially in light of BioSantes pending merger with ANIP Acquisition Company d/b/a ANI Pharmaceuticals, Inc. (ANI). The decision to sell the assets related to the GVAX cancer vaccine portfolio was made by BioSante after an extensive sale/licensing process in order to maximize the current and potential future value of the GVAX cancer vaccine portfolio to the BioSante stockholders.
