Lay Description

The purpose of this first-in-human (FIH) study of BLZ945 given as a single agent or in combination with PDR001 is to characterize the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and anti-tumor activity of BLZ945, administered orally, as a single agent or in combination with PDR001, administered intravenously (i.v.) in adult patients with advanced solid tumors.

Dose escalation will be guided by a Bayesian logistic regression model with overdose control. Once MTD/ RP2D is declared, glioblastoma patients will be enrolled in the phase II part to further assess the preliminary anti-tumor activity of BLZ945 as single agent and in combination with PDR001.
