Comparing Fianlimab Plus Cemiplimab to Relatlimab Plus Nivolumab in Adults With Advanced or Metastatic Melanoma A Phase 3 Randomized Study

What this Trial Is About

Researchers are evaluating the safety and effectiveness of an experimental drug combination, fianlimab and cemiplimab, compared to the approved combination of relatlimab and nivolumab Opdualag in adults with advanced or metastatic melanoma, a serious type of skin cancer. This Phase 3 study aims to understand how well these treatments work and what side effects they may cause. The study also investigates how much of the study drugs are present in the blood over time and whether the body produces antibodies against these drugs. Participants are randomly assigned to receive either the experimental combination of fianlimab plus cemiplimab given intravenously every three weeks or the approved combination of relatlimab plus nivolumab given intravenously every four weeks. The study compares these two treatments in parallel groups. Treatments are administered during the study period, and participants are monitored regularly to assess the effects and safety of the medications. During the trial, participants undergo assessments including tumor measurements following standardized criteria to evaluate response to treatment. The study also monitors for adverse events, laboratory abnormalities, and the presence of anti-drug antibodies. The main outcome measure is the objective response rate, evaluated over up to 72 months. Participants are followed for safety and effectiveness throughout this period, which may last several years in total.
