Onconova Therapeutics Inc. To Present New Data On Rigosertib And Earlier-Stage Programs At The 2015 American Association for Cancer Research Annual Meeting

NEWTOWN, Pa., April 7, 2015 (GLOBE NEWSWIRE) -- Onconova Therapeutics, Inc. (Nasdaq:ONTX) a clinical-stage biopharmaceutical company focused on discovering and developing novel products to treat cancer, today announced the presentation of pre-clinical data of its leading proprietary compounds at the 2015 AACR Annual Meeting being held April 18-22, 2015 at the Pennsylvania Convention Center in Philadelphia, PA.

Three abstracts relating to clinical-stage compounds rigosertib and briciclib, and three abstracts relating to pre-clinical-stage compounds, are scheduled to be presented. The presentations are listed below.

"Our presence at AACR will showcase the innovative advances in cancer treatment being pioneered by Onconova and our collaborators," said Ramesh Kumar, Ph.D., President and CEO of Onconova. "The AACR presentations will highlight the depth of our clinical and pre-clinical pipeline, including rigosertib for the treatment of myelodysplastic syndromes, briciclib for the treatment of advanced solid tumors refractory to current therapies, as well as multiple pre-clinical oncology programs. We are excited to detail some of our most recent scientific advances at the prestigious AACR conference."

About Rigosertib

Rigosertib is a small molecule that inhibits cellular signaling by acting as a Ras mimetic. This is believed to be mediated by direct binding of rigosertib to the Ras-binding domain (RBD) found in many Ras effector proteins, including the Raf kinases and PI3K. The initial therapeutic focus for rigosertib is myelodysplastic syndromes (MDS), a group of bone marrow disorders characterized by ineffective formation of blood cells that often converts into acute myeloid leukemia (AML). Clinical trials with intravenous (IV) and oral formulations of rigosertib are being conducted at leading institutions in the U.S. and Europe.
