New hope for hard-to-treat melanoma: drug combo targets NRAS mutation
NCT ID NCT04835805
First seen Jun 27, 2026 · Last updated Jul 02, 2026 · Updated 2 times
Summary
This early-stage study tests a new drug called belvarafenib, alone or with other drugs (cobimetinib and nivolumab), in people with advanced melanoma that has a specific NRAS gene change and has stopped responding to standard immunotherapy. The main goals are to check safety and find the right dose. About 65 adults with this type of melanoma will take part.

Inclusion Criteria: * ECOG Performance Status of 0 or 1 * Histologically confirmed, metastatic (recurrent or de novo Stage IV) or unresectable locally advanced (Stage III) cutaneous melanoma, that has progressed on or after treatment with anti-PD-1 or anti-PD-L1 therapy. Patients may have received up to two lines of systemic cancer therapy. Treatment with anti-PD-1/PD-L1 in the adjuvant setting is acceptable. Patients must have progressed disease at study entry * Documentation of NRAS mutation-positive within 5 years prior to screening * Tumor specimen availability * Adequate hematologic and end-organ function * Measurable disease per RECIST v1.1 Exclusion Criteria: * Prior treatment with a pan-RAF inhibitor * Treatment with systemic immunotherapy agents (e.g., anti-CTLA4, anti-PD(L)1, cytokine therapy, investigational therapy, etc.) within 28 days prior to C1D1 * Symptomatic, untreated, or actively progressing CNS metastases * History or signs/symptoms of clinically significant cardiovascular disease * Known clinically significant liver disease * History of autoimmune disease or immune deficiency * Prior treatment with a MEK inhibitor (cobimetinib arm) * History of or evidence of retinal pathology on ophthalmologic examination (cobimetinib arm) * History of immune-related AE attributed to prior anti-PD(L)1 therapy that resulted in permanent discontinuation of anti-PD(L)1 therapy (nivolumab arm)
