Part 1: Dose escalation and expansion of APG-115 monotherapy in pediatric neuroblastoma or solid tumors to determine MTD and recommended phase 2 dose, RP2D.~Part 2: Dose escalation of APG-2575 to determine the MTD and RP2D combined with APG-115 at the dose level determined in part 1 in pediatric neuroblastoma or solid tumor, and extend the RP2D level of the combination therapy.
An open, non-randomized Phase I trial of dose-escalation and cohorts expansion to evaluate the safety, pharmacokinetic profile and initial efficacy of APG-115 alone or in combination with APG-2575 in the treatment of recurrent or refractory pediatric neuroblastoma or solid tumors.
