Nivolumab + Ipilimumab Comparison Study (Melanoma)

We are doing this study to compare different treatment options for people who have surgery to remove melanoma. We want to know if it is better to treat people with nivolumab alone after surgery, or if it is better to give people a combination of nivolumab and ipilimumab.

Resectable Melanoma

Adults ages 18+ who:

• Are diagnosed with stage III resectable melanoma
• Do not have uveal or mucosal melanoma

For more information about who can join this study, please contact the study team at kayotta.johnson@duke.edu.

The study is divided into 2 periods: a screening period and a study dosing period.

If you choose to join the study, you will go through a screening period to see if you are eligible. During this period, you will:

• Have a physical exam
• Answer questionnaires
• Have blood draws
• Have imaging scans (X-Ray, MRI, CT, or PET)
• Have a tumor biopsy

If you are eligible to proceed to the study dosing period, you will:

• Take a fixed dose of 480 mg nivolumab
• Have surgery to remove your tumor about 4 weeks later

After surgery, we will test what kind of cells you have left where the tumor was removed. If less than 10% of the cells are viable tumor cells, this will be considered a complete or near complete response. You will not have any further treatment.

If you do not have a complete or near complete response, you will get a random assignment (like a coin flip) to 1 of 2 different treatment arms:

• One treatment arm will get a dose of nivolumab every 4 weeks
• The other treatment arm will get nivolumab and ipilimumab every 3 weeks
