In vivo efficacy of SAR405838 in heterotopic and orthotopic models of GBM108
A, B) Average flank tumor volume of surviving mice in placebo (black, n=7) vs. SAR405838 at 50 mg/kg p.o. qd until euthanasia (grey, n=8). Solid arrows at treatment start date. Mice were euthanized once tumor exceeded 1800 mm3. C) In vivo (flank) expression of p21 and PUMA is increased at 24 h after SAR405838 (50 mg/kg) in GBM108 but not GBM102. D) SAR405838 at the same dosing regimen does not demonstrate efficacy in an orthotopic model of GBM108. (Placebo : black (n=12), Treated : grey (n=11)) * P<0.05, ** P<0.01, *** P<0.001.
