Pilot Study of SBRT and CDX-1127 in Prostate Cancer

Phase 1
Terminated
Conditions
Prostatic Neoplasms
Prostate Cancer
Registration Number
NCT02284971
Lead Sponsor
James Larner, MD
Brief Summary

This study evaluates the combination of stereotactic body radiation therapy (SBRT) and CDX-1127 in subjects with castration resistant prostate cancer. Subjects will be randomized to one of three arms to receive SBRT prior to, after, or in conjunction with the first dose of CDX-1127.

Detailed Description

This pilot study will be conducted in subjects with metastatic prostate cancer in order to define whether inclusion of immune regulation agents such as CDX-1127 augments immune responses to SBRT-treated primary tumors or metastases, and whether inclusion of CDX-1127 in the treatment regimen results in immune responses in untreated metastases.
