    Combination treatment. (a) Comparison of AZD-8055 and ABT-263 treatment in all cell lines. Red indicates sensitivity, while blue indicates resistance. (b) Depiction of synergism where the values shown are excess over Bliss Independence, a prediction of inhibition without synergism. Increased synergism is evident by an increased number, shown in red, while negative numbers in blue represent an antagonistic effect.

    Description

    Navitoclax (ABT-263) is a potent and oral Bcl-2 family protein inhibitor that binds to multiple anti-apoptotic Bcl-2 family proteins, such as Bcl-xL, Bcl-2 and Bcl-w, with a Ki of less than 1 nM.

    IC50 & Target[1]

    Bcl-W

    1 nM (Ki)

    Bcl-xL

    1 nM (Ki)

    Bcl-2

    1 nM (Ki)

    In Vitro

    Navitoclax (ABT-263) is active against approximately one-half of the cell lines of the PPTP in vitro panel. The median IC50 for all of the lines in the panel is 1.91 µM[1]. Navitoclax in combination with chemotherapy agents leads most ovarian cancer cell lines a synergistic response, and enhances the caspase activation in both SK-OV-3 and IGROV-1 cell lines[2].

    In Vivo

    Navitoclax (100 mg/kg; orally; 21-day treatment) enhances the activity of OSI-744 in vivo. As a single agent, 100 mg/kg Navitoclax alone dosed daily has no significant antitumor activity, whereas daily dosing of OSI-744 at 50 mg/kg results in significant tumor stasis (%TGI=52) during a 21-day treatment period. Notably, the combination of Navitoclax and OSI-744 dosed daily for 21 consecutive days results in 98% TGI and durable tumor regressions in 100% of treated tumor-bearing mice[3].

    Animal Model: Mice with NCI-H1650 model[3]
    Dosage: 100 mg/kg
    Administration: Orally; daily; for 21 consecutive days
    Result: As a single agent, 100 mg/kg alone dosed daily had no significant antitumor activity. Notably, the combination with OSI-744 resulted in 98% TGI and durable tumor regressions in 100% of treated tumor-bearing mice.
