Tolerability and Pharmacokinetics of Toripalimab in Combination With Axitinib in Patients With Kidney Cancer and Melanoma

This is a phase Ib, open, mono-center, dose-escalation, tolerability and pharmacokinetic study evaluating the Recombinant Humanized Anti-PD-1 mAb for Injection in combination with Axitinib in patients with advanced kidney cancer and melanoma who have failed in routine systemic treatment.The study will be conducted in 2 parts: dose escalation and cohort expansion. 18 to 24 patients will be enrolled in dose escalation part.This part is to analyze safety and efficacy of the humanized anti-PD-1 antibody in combination with axitinib and to confirm dose-limiting toxicity (DLT), maximum tolerated dose (MTD) and recommended dose (RD). After finishing the dose escalation part, we will enroll other patients for each tumor types of recommended dose group to ensure each group have 10 patients. This part is to further analyze safety and efficacy of the humanized anti-PD-1 antibody.
