Study Summary

This trial is testing whether a combination of two drugs is better than one drug at treating cancer. The study will also look at the side effects of the drugs and how well they work in children.

Who is the study for?
Adolescents and adults with advanced melanoma that hasn't spread too much can join this trial. They should be over 12 years old, have a life expectancy of at least 3 months, and not have had previous systemic treatments for their condition. People with certain types of melanoma or those who are immunocompromised can't participate.Check my eligibility
What is being tested?
The study is testing if combining two drugs, Fianlimab and Cemiplimab, works better than Pembrolizumab alone in stopping the cancer from progressing. It also looks at overall survival rates, response to treatment, safety in young people (12-18), quality of life impacts, and how the body processes the drugs.See study design
What are the potential side effects?
Possible side effects include immune system reactions that could affect organs or cause infections; infusion-related reactions; fatigue; skin issues like rash; hormonal imbalances requiring hormone therapy; digestive problems such as diarrhea or liver inflammation.
