About the MM1636 Clinical Trial

The MM1636 trial (ClinicalTrials.govNCT03047928), an investigator-initiated trial at the Copenhagen University Hospital, Herlev, enrolled 30 patients with metastatic melanoma. In this Phase 1/2 clinical trial, patients received the multi-antigen immunotherapeutic, IO102-IO103, in combination with the anti-programmed death 1 (PD-1) antibody nivolumab as first line treatment. Patients were treated with nivolumab every second week as long as there was a clinical benefit or no adverse events prohibiting further treatment. IO102-IO103 was given from the start of administration of nivolumab and every second week for the first six weeks and thereafter, every fourth week for 41 weeks. The trial objectives were to assess safety, immune response in blood and biopsies as well as efficacy.
