Tolero Pharmaceuticals Presents Findings from Preclinical Studies Evaluating Investigational Agents TP-1287 in Prostate Cancer Models and TP-1454  in Colorectal Cancer Models

SALT LAKE CITY, Utah, Oct. 29, 2019 /PRNewswire/ -- Tolero Pharmaceuticals, Inc., a clinical-stage company focused on developing novel therapeutics for hematological and oncological diseases, announced today the presentation of preclinical data of TP-1287, an investigational oral cyclin-dependent kinase 9 (CDK9) inhibitor, in castration-sensitive and resistant prostate cancer models and TP-1454, an investigational small-molecule pyruvate kinase M2 isoform (PKM2) activator, in colorectal cancer models. These data were shared at the 2019 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, being held October 26-30, 2019, in Boston, Massachusetts.

"We are pleased to present data on our early-stage investigational agents, TP-1287 and TP-1454. These results are a testament to our commitment to develop novel therapeutics and expand the combined oncology portfolio of Tolero and its parent company, Sumitomo Dainippon Pharma," said David J. Bearss, Ph.D., Chief Executive Officer of Tolero Pharmaceuticals, Inc. "Furthermore, these data improve our understanding of these assets and provide insight into the potential role CDK9 inhibition and PKM2 activation may play in the treatment of prostate and colorectal cancer." 

Data from a preclinical prostate cancer model, showed TP-1287 as monotherapy and in combination with venetoclax or docetaxel enhanced tumor growth inhibition. Additionally, TP-1287 combined with docetaxel alone showed tumor growth inhibition.

In a separate preclinical colorectal cancer model, TP-1454 in combination with anti-PD1 and anti-CTLA4 therapies showed tumor regression, tumor growth inhibition and an acceptable safety profile.

Below are the details for the Tolero presentations:
