This is a Phase I/II, open-label, non-randomized study to evaluate the safety, tolerability, pharmacokinetics, and anti-tumor activity of BPI-361175 tablets in patients with advanced NSCLC with EGFR C797S mutation and other EGFR-related mutations. Adult patients (18 and above) will receive a single dose of BPI-361175 followed by a 7-day washout period with continuous oral dosing of BPI-361175 in 28 days cycle.~This is a three-stage study, consisting of Phase Ia dose-escalation, Phase Ib dose expansion, and pivotal Phase II study.~It is expected to provide a brand-new treatment for advanced NSCLC. The study design utilizes a Bayesian Optimal Interval (BOIN) method to guide the dose level assignment of BPI-361175 and estimate the MTD/RP2D based on cumulative information on DLTs in the Cycle 0 + Cycle 1 of treatment.
This is a three-stage study, consisting of Phase Ia dose-escalation, Phase Ib dose expansion, and a Phase II component.
