Brief summary
This treatment study for relapsed high-risk neuroblastoma, Ewings sarcoma, osteogenic sarcoma, rhabdomyosarcoma or synovial sarcoma involves an autologous cancer testis (CT) antigen specific dendritic cell (DC) vaccine preceded by decitabine as a demethylating chemotherapy.
Detailed description
For vaccine production, mature DC will be pulsed with overlapping peptides mixes derived from full-length NY-ESO-1, MAGE-A1, and MAGE-A3.
Interventions
Week 1: Decitabine (DAC): 10 mg/m2/day IV (Mon-Fri) Weeks 2 and 3: Vaccine: 3-5 E6 peptide pulsed DC (Mon) Hiltonol applied topically to vaccine site before and after vaccination
