BBI608 is an anti-cancer drug created and currently under development (Phase 3 in North America) by Boston Biomedical Inc. BBI608 has a novel mechanism that shows anti-tumor effects by targeting cancer stem cells (cancer cells with stem cell-like properties) as well as other heterogeneous cancer cells. By targeting cancer stem cells in addition to heterogeneous cancer cells, efficacy is expected in the current challenges in therapy against cancer, such as treatment resistance, metastasis and recurrence.
