Decitabine Followed by a Cancer Antigen Vaccine for Patients With Neuroblastoma and Sarcoma

Phase 1
Completed
Conditions
Osteogenic Sarcoma
Neuroblastoma
Ewings Sarcoma
Rhabdomyosarcoma
Synovial Sarcoma
Interventions
Biological: Autologous dendritic cell vaccine with adjuvant
Registration Number
NCT01241162
Lead Sponsor
University of Louisville
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.
