Clinical Trial Summary

This is A Multicenter, Open-Label, Phase 1/2 Study to Evaluate the Safety, Efficacy, and Pharmacokinetics of YL201 in Patients with Selected Advanced Solid Tumors. The study will include 2 parts: Phase 1 dose expansion stage (Part 1) followed by a Phase 2 stage with expanded sample size (Part 2). Part 1 will estimate the RP2D in dose expansion cohorts of patients with not linited to non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), nasopharyngeal carcinoma (NPC), esophageal squamous cell carcinoma (ESCC), metastatic castration-resistant prostate cancer (mCRPC), etc.. Part 2 will include patients with selected advanced solid tumor types enrolled at the RP2D to further assess the efficacy and safety of YL201.
