Synta Announces Presentations at the 2015 Annual Meeting of the American Association of Cancer Research

LEXINGTON, Mass.--(BUSINESS WIRE)--Apr. 16, 2015-- Synta Pharmaceuticals Corp. (NASDAQ: SNTA) announced today that poster presentations related to studies with ganetespib, a novel, potent small molecule inhibitor of heat shock protein 90 (Hsp90) in Phase 3 development, and STA-12-8666, the company’s leading candidate from its proprietary Hsp90 inhibitor Drug Conjugate (HDC) Program, will be presented at the 2015 Annual Meeting of the American Association of Cancer Research (AACR) in Philadelphia, Pennsylvania.

“Preclinical data presented at this year’s AACR meeting add to the body of data supporting the potential benefit of combining ganetespib with multiple therapeutic modalities in the treatment of various cancers, including non-small cell lung cancer. These data continue to provide support for our broad clinical strategy, including the ongoing Phase 3 GALAXY-2 trial and our large, randomized, investigator-sponsored studies, and will help shape our future clinical direction,” said Anne Whitaker, President and Chief Executive Officer of Synta. “In addition, we continue to see highly encouraging preclinical proof of concept data for our lead HDC candidate, STA-12-8666, in several animal models, including resistant pancreatic cancer and small cell lung cancer patient derived xenografts. We are encouraged by the progress of this program and look forward to moving toward an IND submission by the first quarter of 2016.”
