Summary

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.

Conditions

  • Melanoma Metastatic
  • NRAS Mutation

Interventions

DRUG

Tunlametinib

Tunlametinib (3 mg/tablet): The recommended dose is 12 mg (4 tablets) orally twice daily (approximately every 12 hours), with or without food. Capsules must not be chewed, dissolved, or opened. If a dose is missed, it may be taken up to 8 hours before the next scheduled dose; if the missed dose is discovered within 8 hours of the next dose, it should be skipped.

DRUG

Pucotenlimab

PD-1 antibody (pucotenlimab): Administered via intravenous infusion over at least 60 minutes, using an in-line filter (0.2-5 μm). The drug is diluted with normal saline prior to infusion. One treatment cycle is defined as 3 weeks (21 days).

DRUG

Hydroxychloroquine (HC)

Hydroxychloroquine (0.1 g/tablet): Administered orally at 2 tablets (0.2 g) twice daily, to be taken with meals or milk. Each treatment course consists of 4 consecutive weeks of administration, i.e., 30 days per course.
