ACTB-1003 is an oral kinase inhibitor targeting cancer mutations (FGFR inhibition), angiogenesis (inhibition of VEGFR2 and Tie-2) and induces apoptosis (targeting RSK and p70S6K, downstream of PI3 kinase). The multi-activity of ACTB- 1003 translates to in vivo efficacy with dose-dependent tumor growth inhibition in a variety of histological cancers including lung, breast and colorectal. ACTB-1003 is an oral kinase inhibitor with multiple modes of action, targeting cancer mutations via FGFR inhibition FGFR1 (IC50=6 nM), angiogenesis through inhibition of VEGFR2 (2 nM), Tie-2 (4 nM), and induces apoptosis likely by targeting RSK (5 nM) and p70S6K (32 nM). ACTB-1003 is highly active with dose-dependent tumor growth inhibition in cell lines with FGFR genetic alterations - OPM2 human multiple myeloma and the murine leukemia Ba/F3-TEL-FGFR1.
