Boston Biomedical Announces Presentations for Investigational First-in-Class Cancer Stemness Inhibitors Napabucasin and Amcasertib in Multiple Tumor Types at ASCO 2017

CAMBRIDGE, Mass., May 18, 2017 /PRNewswire/ -- Boston Biomedical, Inc., an industry leader in the development of next-generation cancer therapeutics designed to inhibit cancer stemness pathways, today announced it will feature 11 clinical data poster presentations on investigational compounds evaluating napabucasin and amcasertib in nine different tumor types at the upcoming 2017 American Society of Clinical Oncology (ASCO) Annual Meeting, held from June 2-6, in Chicago.

Clinical data results from phase 1 and 2 studies assessing napabucasin – the company's most advanced orally-administered investigational agent designed to inhibit cancer stemness pathways by targeting STAT3 – showed encouraging anti-cancer activity in multiple tumor types, including updated data for advanced ovarian and non-squamous non-small cell lung cancers. For the first time, data in advanced melanoma will be presented. Further, the company will present updated metastatic colorectal cancer (mCRC) and pancreatic cancer data, which support the ongoing napabucasin, phase 3 clinical trials: CanStem303C (mCRC) and CanStem111P (metastatic pancreatic cancer).

In addition, results of a phase 1b/2 study investigating either napabucasin or amcasertib in combination with sorafenib in hepatocellular carcinoma will be presented. Amcasertib is an orally-administered investigational agent designed to inhibit cancer stemness pathways, including Nanog, by targeting stemness kinases, which is currently being investigated in phase 1 and 2 clinical studies.

"We are excited to share new clinical data results for our investigational first-in-class cancer stemness pathway inhibitors – napabucasin and amcasertib – at the 2017 ASCO Annual Meeting," said Patricia S. Andrews, Chief Executive Officer, Boston Biomedical, Inc. "These data highlight the depth and potential of our growing clinical development pipeline and reinforce our continued commitment to advancing novel treatment options for cancers with a high unmet need."

Planned poster sessions include:

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 3 studies, including advanced 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 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.

About Amcasertib
Amcasertib is an orally-administered investigational agent designed to inhibit cancer stemness pathways, including Nanog, by targeting stemness kinases. Boston Biomedical is currently investigating amcasertib in nine phase 1 and 2 clinical trials in solid tumors, hepatobiliary cancer, gastrointestinal stromal tumors, urological malignancies, ovarian cancer and hepatocellular carcinoma.
