Boston Biomedical to Present Preclinical Data on Targeting Cancer Stemness at AACR 2017

CAMBRIDGE, Mass. March 9, 2017 – Boston Biomedical, an industry leader in the development of next-generation cancer therapeutics designed to inhibit cancer stemness pathways, will present data from six preclinical studies – including five late-breaking posters – from its research and development portfolio at the upcoming 2017 American Association for Cancer Research (AACR) Annual Meeting held from April 1-5, in Washington, D.C.

One of the featured pre-clinical studies highlights the potential of BBI-801 – a gene-silencing investigational agent designed to inhibit cancer stemness pathways and promote anti-cancer immunity by targeting β-catenin and PD-L1. BBI-801 was discovered through our proprietary asymmetric interfering RNA (aiRNA) technology and is being investigated in preclinical studies.

Additional preclinical data on our first-in-class compounds, napabucasin and amcasertib, will also be shared at the meeting. Napabucasin is an orally-administered investigational agent designed to inhibit cancer stemness pathways by targeting STAT3. Amcasertib is an orally-administered investigational agent designed to inhibit cancer stemness pathways, including Nanog, by targeting stemness kinases.

“Our presentations at this year’s AACR highlight our fundamental research in cancer stemness science and the exciting potential of targeting cancer stemness pathways,” said Chiang J. Li, M.D. FACP, President, CEO, and Chief Medical Officer of Boston Biomedical, and the Head of Global Oncology for Sumitomo Dainippon Pharma Group. “These data underscore our continued commitment to bringing potentially transformative therapies to patients living with cancer.”

About Cancer Stem Cells

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.[i],[ii] Evidence suggests that these cells possess resistance to chemotherapy, radiation and targeted therapy as well as immunotherapies, so while such treatments can successfully shrink tumors, a population of CSCs may still survive.ii,[iii]

Boston Biomedical is leading the biopharmaceutical industry in the development of novel compounds designed to target cancer stemness pathways, with the goal of addressing ongoing challenges in cancer treatment.
