Dendritic Cell Vaccination in Patients With Advanced Melanoma



The purpose of this study is to investigate a method of using dendritic cells (a kind of white blood cell) as a vaccine to stimulate your own immune system to react to your melanoma cells.

Single arm open label trial assessing the safety and tolerability of mDC3/8 Vaccine (Primer and Booster) in subjects with stage III and stage IV melanoma followed by treatment with Pembrolizumab.

Detailed Description

      After consent and screening, subjects will have apheresis performed at approximately day -7
      followed by cyclophosphamide 300mg/m^2 intravenously or by mouth on day -4 to -3. On Day 1
      the subject will receive parin vaccine dose (mature DC 7.5-15 million/peptide) followed by
      two booster doses (every 6 weeks) of mature DC 1-5 million/peptode. Re-staging will occur
      after the 3rd DC vaccine along with tumor biopsy and second apheresis. Anti PD-1 therapy
      (standard of care) will commence 7-8 weeks after the subjects' last DC vaccine.

Trial Arms
