体内研究(In Vivo)
In monotherapy efficacy studies Gartisertib shows tumor stasis to regression in tumor models with alternative lengthening of telomeres (ALT). In combination with PARP inhibitors, tumor regression could be observed in triple-negative breast cancer xenograft models. has not independently confirmed the accuracy of these methods. They are for reference only.
