About Sunesis Pharmaceuticals

Sunesis is a biopharmaceutical company developing new oncology therapeutics for the treatment of solid and hematologic cancers. Sunesis has built an experienced cancer drug development organization committed to improving the lives of people with cancer. The Company is focused on advancing its novel kinase-inhibitor pipeline, with an emphasis on establishing proof of concept that its oral non-covalent BTK-inhibitor vecabrutinib is effective in ibrutinib-resistant chronic lymphocytic leukemia. Vecabrutinib is currently being evaluated in a Phase 1b/2, open-label, sequential-group, dose-escalation and cohort-expansion study in adults with chronic lymphocytic leukemia and other B-cell malignancies who have progressed after prior therapies. Beyond the development of vecabrutinib, the Company has two other kinase inhibitor programs, including the Takeda-partnered pan-RAF inhibitor TAK-580, which is in solid tumor trials, and Sunesis’ proprietary preclinical PDK1 inhibitor SNS-510, which is in preclinical development with an IND submission planned in 2019.  PDK1 is a master kinase that activates other kinases important to cell growth and survival including members of the AKT, PKC, RSK and SGK families.
