This study is an open-label, Phase 1b/2 clinical study. In the Phase 1b study, the safety and tolerability of AZD4547 in patients with advanced solid tumors will be evaluated, the PK of oral AZD4547 in Chinese patients and the recommended phase 2 dose (RP2D) will be determined, and the antitumor activity will be preliminarily assessed. In the Phase 2 study, the efficacy of AZD4547 at the recommended dose in patients with locally advanced or metastatic urothelial carcinoma with FGFR2/3 gene alterations (including mutations and/or fusions) will be evaluated, and the safety, tolerability, and PK of AZD4547 will be further evaluated.
Phase 1b clinical study to evaluate the PK of oral AZD4547 in Chinese patients and RP2D. Phase 2 study to evaluate the efficacy of AZD4547 in urothelial carcinoma patients with FGFR2/3 gene alterations.
