BERKELEY, CA, USA I December 12, 2017 I Aduro Biotech, Inc. (Nasdaq:ADRO), a biopharmaceutical company with three distinct immunotherapy technologies, today provided an update on its clinical development programs for CRS-207, a first-generation proprietary attenuated strain of Listeria that has been engineered to express the tumor-associated antigen mesothelin. Based on preliminary results from its mesothelioma and ovarian studies, as well as a business and commercial assessment, the company has determined that it will not continue advancement of CRS-207 and will wind down each of its trials in mesothelioma, ovarian and gastric cancer. Aduro will be working closely with investigators to proceed in a manner that is aligned with the best interests of patients still being treated on these studies.

“We would like to thank the patients, their families, our clinical investigators and staff for their time and commitment to these trials, which will contribute important data to the field of oncology. While we are disappointed with the results for CRS-207, our clinical development program was designed to quickly generate data that could inform timely decision-making and allow us to prioritize our portfolio accordingly,” said Stephen Isaacs, chairman and chief executive officer of Aduro Biotech. “We will shift our focus and investment toward our STING agonist program, B-select antibodies and personalized neoantigen approach with pLADD. In our STING program in particular, there are several additional clinical trials under consideration to complement our ongoing Phase 1 dose escalation trial of ADU-S100 as well as our combination study with Novartis’ PD-1 checkpoint inhibitor, PDR-001. As a result of our portfolio decisions, we expect our current cash balance to be sufficient to fund planned activities for the next three years through 2020.”
