Boston Biomedical to Highlight Data Examining Novel Investigational Cancer Stem Cell Pathway Inhibitors BBI608 and BBI503 in Multiple Cancer Types at ASCO 2015

CAMBRIDGE, Mass., May 14, 2015 /PRNewswire/ -- Boston Biomedical, an industry leader in the development of novel compounds designed to target cancer stem cell (CSC) pathways, will present clinical data on the investigational compounds BBI608 and BBI503 in multiple tumor types at the 2015 American Society of Clinical Oncology annual meeting, held from May 29 to June 2, 2015, in Chicago, IL.

Data to be highlighted at the meeting show the potential of BBI608—an orally-administered investigational agent that targets STAT3, leading to inhibition of the critical genes for maintaining cancer stemness—for anti-cancer activity when used in combination with other chemotherapeutics across varying advanced cancers, including gastric and colorectal. The study protocol from the BRIGHTER study, the phase 3 clinical trial currently underway to investigate cancer stem cell pathway inhibitors, will also be showcased.

Additional data featuring BBI503—an orally-administered investigational agent designed to inhibit Nanog and other cancer stem cell pathways by targeting kinases—showed encouraging early signs of anti-cancer activity for patients with advanced colorectal cancer.

Also, findings from a publication-only abstract will be available:

• Abstract #e15089: A phase 1 study of BBI608, a cancer stemness inhibitor, administered with paclitaxel (PTX) as combination therapy (Rx) for pretreated unresectable or recurrent gastric cancer
  • Kohei Shitara, MD, National Cancer Center Hospital East

"We look forward to sharing these encouraging findings of first-in-class compounds BBI608 and BBI503 at this year's ASCO annual meeting," said Chiang J. Li, M.D. FACP, the President, CEO and Chief Medical Officer of Boston Biomedical, and the Head of Global Oncology for Sumitomo Dainippon Pharma Group. "We are pleased to see the progress to date and are planning for the continued evaluation of these compounds that may ultimately improve patient care and shift the treatment continuum."
