Trial Summary

What is the purpose of this trial?

This study is researching an experimental drug called REGN3767, also known as fianlimab (R3767), when combined with another medication called cemiplimab (each individually called a "study drug" or called "study drugs" when combined) compared with cemiplimab alone. These types of immunotherapy study drugs are collectively known as immune checkpoint inhibitors. Immunotherapies are treatments that use the immune system to recognize and kill cancer cells. The study is focused on participants with a type of skin cancer known as melanoma. The objective of this study is to see if the combination of fianlimab and cemiplimab is an effective treatment compared to cemiplimab in participants with high-risk, resectable melanoma. Participants will receive treatment before surgery, undergo resection, and then will have the option to continue treatment after resection. The study is looking at several other research questions, including: * What side effects may happen from receiving the study drug(s). * How much study drug(s) is in the blood at different times. * Whether the body makes antibodies against the study drug(s) (which could make the drug less effective or could lead to side effects). Antibodies are proteins that are naturally found in the blood stream that fight infections. * How administering the study drugs might improve quality of life.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot use immunosuppressive doses of corticosteroids within 14 days of starting the study medication.

Is the combination of Fianlimab and Cemiplimab generally safe for humans?

Pembrolizumab, a similar treatment, is generally well tolerated and has a favorable safety profile in treating melanoma. Common side effects include fatigue, rash, itching, and diarrhea, while less common ones include thyroid issues, colitis (inflammation of the colon), hepatitis (liver inflammation), and pneumonitis (lung inflammation). ^{1 2 3 4 5}

What makes the drug combination of Fianlimab and Cemiplimab unique for treating melanoma?

The combination of Fianlimab and Cemiplimab is unique because it involves two immune checkpoint inhibitors that work together to enhance the body's immune response against melanoma. Cemiplimab targets the PD-1 pathway, which helps the immune system recognize and attack cancer cells, while Fianlimab may target a different pathway, potentially offering a more comprehensive approach to treatment. ^{6 7 8 9 10}

What data supports the effectiveness of the drug combination Fianlimab + Cemiplimab for treating melanoma?

Research shows that pembrolizumab, a drug similar to cemiplimab, has been effective in treating melanoma by helping the immune system attack cancer cells. This suggests that cemiplimab, when combined with other drugs like Fianlimab, might also be effective. ^{10 11 12 13 14}
