A Study of APG-115 in Combination With Pembrolizumab in Patients With Metastatic Melanomas or Advanced Solid Tumors
- for people ages 18 years and up (full criteria)

- study startedestimated completion
Part 1 is a phase Ib standard "3 + 3" design will be employed to determine the MTD of APG-115 by assessing the DLT of APG-115 in combination with pembrolizumab. Part 2 is a Simon two-stage phase II study design. At RP2D of APG-115 in combination with pembrolizumab, approximately 43 patients will be treated with the combination until disease progression, unacceptable toxicity, or another discontinuation criterion is met.
A Phase Ib/II Study of APG-115 in Combination With Pembrolizumab in Patients With Unresectable or Metastatic Melanomas or Advanced Solid Tumors
Part 1 is the open label, dose-escalation phase Ib portion of the study to establish an MTD/RP2D of APG-115 in combination with pembrolizumab. Dose levels/schedule of APG115 will be tested: 50mg, 100mg, 150mg, and 200mg, QOD with 2 weeks on 1 week off as a cycle of 21 days (3 weeks), pembrolizumab will administrated with label dose. Part 2 is the phase II portion of the study to evaluate the clinical efficacy and safety of the RP2D of APG-115 in combination with label dose of pembrolizumab in patient with unresectable or metastatic melanoma who is refractory or relapse of PD1 therapy. In this part, Simon's two-stage design (Simon R (1989). Controlled Clinical Trials 10: 1-10.) will be used. The null hypothesis that the true response rate is 10% or lower will be tested against a one-sided alternative. In the first stage, 18 patients will be accrued. If there are 2 or fewer responses in these patients, the study will be stopped. Otherwise, 25 additional patients will be accrued for a total of 43. The null hypothesis will be rejected if 8 or more responses are observed in 43 patients. This design yields a type I error rate of 0.10 and power of 80% when the true response rate is 25% or higher.
