Summary

This is a multicenter, open-label phase 1/2a study consisting of two parts: dose escalation phase and dose expansion phase. The objective of the dose escalation phase is to evaluate the safety, tolerability and pharmacokinetics of JAB-21822 in combination with JAB-3312 in patients with advanced solid tumors harboring KRAS p.G12C mutation and to determine the RP2D for the combination therapy. In the dose expansion phase, preliminary efficacy and safety of the combination therapy at the RP2D will be further explored in patients with specific cancer harboring KRAS p.G12C mutation.

Official title: A Phase 1/2a Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Antitumor Activity of JAB-21822 in Combination With JAB-3312 in Patients With Advanced Solid Tumors Harboring KRAS p.G12C Mutation
