NRAS Mutation

This study evaluates the combination of the autophagy inhibitor hydroxychloroquine (HCQ), the MEK inhibitor tunlametinib, and the anti-PD-1 antibody pucotenlimab in patients with locally advanced or metastatic melanoma. The primary objectives are to assess the objective response rate (ORR) and progression-free survival (PFS). Secondary objectives include evaluating adverse events (type, severity, and incidence), duration of response (DOR), disease control rate (DCR), and overall survival (OS), as well as exploring the molecular mechanisms by which autophagy modulation enhances immunogenicity in mutant melanoma. Further exploratory analyses will examine the mechanisms by which autophagy inhibition enhances tumor sensitivity to PD-1 blockade, thereby establishing experimental and theoretical grounds for refining future clinical approaches.

This is a Phase 1 first-in-human, open-label multicenter study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and preliminary antitumor activity of RLY-8161, an NRAS-selective inhibitor, in participants with advanced NRAS-mutant melanoma and other solid tumors.
