Summary

This trial tests if a peptide vaccine combined with boosters and a special antibody is safe and can improve immune responses. The study will check blood and tissue samples to see how well the treatment works.

Who is the study for?
This trial is for adults over 18 with stage II-IV melanoma, who are currently free of disease post-treatment or surgery. They must have good performance status and organ function, not be pregnant or breastfeeding, and without a history of certain autoimmune disorders or recent treatments that could interfere with the study.
What is being tested?
The trial tests the safety and immune response to a peptide vaccine (6MHP) combined with adjuvants Montanide ISA-51 and polyICLC, plus CDX-1127 monoclonal antibody in some participants. It's evaluating if these substances can boost the body's defense against melanoma when given together.
What are the potential side effects?
Potential side effects may include typical reactions at the injection site like pain or swelling, flu-like symptoms such as fever or fatigue, allergic responses to vaccine components, and possible immune-related effects due to CDX-1127.

Experimental Treatment
Group I: Arm B: 6MHP/Montanide ISA-51 + polyICLCExperimental Treatment3 Interventions
200 mcg of 6MHP plus 0.9 mg of polyICLC emulsified in Montanide ISA-51 adjuvant will be administered subcutaneously on days 1, 8, 15, and 36. 200 mcg of 6MHP in Montanide ISA-51 adjuvant (without polyICLC) will be administered subcutaneously/intradermally on day 176.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Common treatments for melanoma, such as immune checkpoint inhibitors (e.g., nivolumab and ipilimumab) and peptide vaccines, work by enhancing the body's immune response against cancer cells. Immune checkpoint inhibitors block proteins that prevent T-cells from attacking cancer cells, thereby boosting the immune system's ability to target and destroy melanoma cells. Peptide vaccines, like the 6MHP with adjuvants, introduce specific antigens to the immune system, prompting it to recognize and attack melanoma cells more effectively. The addition of adjuvants and monoclonal antibodies like CDX-1127 further amplifies this immune response. These mechanisms are crucial for melanoma patients as they can lead to more effective and durable responses against the cancer, potentially improving survival rates and quality of life.
