Description: For this single-arm, open-table, phase 1/2 trial (ClinicalTrials.gov Identifier: NCT02385669), researchers are evaluating whether 6MHP, a peptide vaccine, is safe and efficacious when combined with ipilimumab in patients with stage IIIB or higher melanoma.

6MHP is made up of 6 peptides from melanoma proteins. The vaccine will be delivered intradermally and subcutaneously alongside ipilimumab 3 mg/kg once per 21 days.

The primary endpoints are safety, CD4+ T cell responses, and disease control rate.
