Phase I Study Comparing HLX17 and US-Sourced Keytruda for Resected Non-Small Cell Lung Cancer, Melanoma, and Renal Cell Carcinoma

What this Trial Is About

Researchers are conducting a multicenter, randomized, double-blind, parallel-controlled phase I clinical study to compare HLX17 and US-sourced Keytruda in patients with resected non-small cell lung cancer, melanoma, or renal cell carcinoma. The study aims to evaluate how similar the pharmacokinetic profiles, efficacy, safety, and immune responses are between these two treatments in this patient population. Participants will receive either HLX17 or US-sourced Keytruda. Those in the HLX17 group will get 200 mg on Day 1 of every 3-week cycle for up to 12 months or until disease recurrence, death, new anti-tumor therapy, unacceptable toxicity, consent withdrawal, or study end. The Keytruda group will receive 200 mg every 3 weeks for 8 cycles 24 weeks, then switch to HLX17 on the same schedule until 12 months or similar conditions occur. During the study, participants will undergo various assessments including pharmacokinetic measurements such as drug concentration over time and at steady state, disease-free survival evaluation for up to 12 months, and monitoring for adverse events and laboratory abnormalities for up to 15 months. Safety follow-up includes vital signs, physical exams, ECGs, and immunogenicity evaluation. The total study duration includes treatment and safety monitoring phases.
