A, ‘Waterfall’ plot showing the maximal tumor volume regression (100% is a volume below level of detection ~40 mm3) in mice treated with a single administration of PLX038A; B, “Swimmer’ plot showing the EFS for 31 xenograft models in treated xenografts. Tumors marked with an asterix are those where there was no detectable tumor at termination of the experiment at day 140. C, The relationship between the maximal tumor volume reduction and EFS for 31 xenograft models in mice treated with PLX038A (R2 = 0.2293). Arrows mark overlapping coordinates for SK-NEP-1 and RBD-2 [day 38] and Rh36, EW-8, TC-71, KT5 and KT11 [day 140]).
