A Phase 3 Randomized, Controlled Study of IMC-F106C Plus Nivolumab Versus Nivolumab Regimens in HLA-A*02:01-Positive Participants With Previously Untreated Advanced Melanoma (PRISM-MEL-301
This is a phase 3, randomized, controlled study of brenetafusp (IMC-F106C) plus nivolumab compared to standard nivolumab regimens in HLA-A*02:01-positive participants with previously untreated advanced melanoma.
Inclusion: Participants must be HLA-A*02:01-positive; Participants must have histologically confirmed Stage IV or unresectable Stage III melanoma; Archived or fresh tumor tissue sample that must be confirmed as adequate; Participants must have measurable disease per RECIST 1.1; Participant must have BRAF V600 mutation status determined; Participants must have an Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1; Male and female participants of childbearing potential who are sexually active with a non-sterilized partner must agree to use highly effective methods of birth control from the study screening date until 5 months after the final dose of study intervention.
Exclusion: Participants who received prior systemic anticancer therapy for unresectable or metastatic melanoma; Participants with a history of a life-threatening AE related to prior anti-PD-(L)1 or anti-LAG-3; Participants with a history of a malignant disease other than those being treated in this study; Hypersensitivity to IMC-F106C, nivolumab, relatlimab, or any associated excipients; Participants with clinically significant pulmonary disease or impaired lung function; Participants with clinically significant cardiac disease or impaired cardiac function; Participants with active autoimmune disease requiring immunosuppressive treatment; Participants with any medical condition that is poorly controlled or that would, in the Investigator's or Sponsor's judgment, adversely impact the participant's participation in the clinical study due to safety concerns, compliance with clinical study procedures, or interpretation of study results; Participants with untreated, active, or symptomatic central nervous system (CNS) metastases or carcinomatous meningitis.
