Boston Biomedical to Highlight Data for Cancer Stemness Inhibitor Napabucasin in Patients with Colorectal Cancer at 2017 ASCO GI

CAMBRIDGE, Mass., Jan. 18, 2017 /PRNewswire/ — Boston Biomedical, an industry leader in the development of novel compounds designed to target cancer stemness pathways, will feature data from two clinical studies for its lead investigational compound, napabucasin, at the 2017 ASCO Gastrointestinal Cancers Symposium, held from January 19-21, in San Francisco.

Napabucasin is an orally-administered investigational agent designed to inhibit cancer stemness pathways by targeting STAT3.i Cancer stem cells (CSCs) possess the property of stemness – the ability to self-renew and differentiate into heterogeneous cancer cells. This allows the CSCs to act like seeds, causing a patient’s cancer to relapse or spread within the body.ii,iii In preclinical studies, the STAT3 pathway was identified as an important pathway for maintaining cancer stemness.

Data from the two studies will be presented as poster presentations on January 21. The studies evaluate anti-cancer activity of napabucasin in combination with FOLFIRI with and without bevacizumab in patients with metastatic colorectal cancer (CRC), including treatment-naïve patients and patients previously exposed to FOLFIRI regardless of pSTAT3 status, and safety and anti-cancer activity of napabucasin in combination with panitumumab in patients with K-ras wild type metastatic colorectal cancer (mCRC).

Planned data posters include:

Saturday, January 21, from 7:00 AM – 7:55 AM and 12:30 PM – 2:00 PM PST; Moscone West Building

About Napabucasin

Napabucasin is an orally-administered investigational agent designed to inhibit cancer stemness pathways by targeting STAT3.i

Napabucasin is currently being investigated in multiple Phase III studies, including gastric and gastroesophageal junction (GEJ) (NCT02178956), colorectal (NCT02753127) and pancreatic cancer (NCT02993731). It is also being investigated in earlier phases in multiple solid and hematologic malignancies, including tumors of the lung, liver, pancreas and brain. In 2016, the U.S. Food and Drug Administration granted Orphan Drug Designation for napabucasin in gastric/GEJ and pancreatic cancer.
