BERKELEY, CA, USA I February 9, 2015 I Aduro Biotech, Inc. today announced that it has achieved its first milestone under its collaboration with Janssen Biotech, Inc., by initiating toxicology studies to support an Investigational New Drug Application for ADU-741, an immuno-oncology product candidate for the treatment of prostate cancer. The Janssen decision to advance ADU-741 toward clinical trials was based on preclinical data generated in the first eight months of the collaboration. This accomplishment triggered a milestone payment to Aduro.

In May 2014, Aduro entered into an agreement granting Janssen an exclusive, worldwide license to certain product candidates specifically engineered for the treatment of prostate cancer based on its novel LADD immunotherapy platform. Under the agreement, facilitated by Johnson & Johnson Innovation, California, Aduro is eligible to receive up to a potential total of $365 million in upfront license fees and milestone payments upon achievement of defined development, regulatory and commercialization milestones, if multiple programs advance to commercialization, as well as tiered royalties on worldwide net sales.

“This is an important validation of our ability to rapidly engineer new product candidates from our LADD platform,” said Stephen T. Isaacs, chairman, president and chief executive officer of Aduro. “We are pleased to earn the associated milestone payment and importantly to see our technology progress toward clinical trials to evaluate its utility in prostate cancer.”
