Antitumor activity of BAY 94-9343 in patient-derived tumor models. Antitumor activity of BAY 94-9343 in patient-derived tumor models. Fragments of human tumors were passaged in naïve immunocompromised mice. After randomization into groups, treatments (BAY 94-9343 and S-methyl-DM4 i.v., gemcitabine i.p., cisplatin i.p.) were initiated (time points indicated by arrows). Mean ± SD of tumor volume for the pancreatic cancer model PAXF736 (n = 9; A), ovarian cancer model OVCAR6719 (n = 8; B), and mesothelioma model Meso7212 (n = 10; C). Sven Golfier et al.
