Arms & Interventions

Arm A: HDCRT administered with first dose of pembrolizumabexperimental

Pembrolizumab (200 mg) plus HDCRT (24 Gy in 3 fractions of 8 Gy each for bone and/or soft tissue lesions; 30 Gy in 5 fractions of 6 Gy each for the prostate gland) are both administered beginning on day 1. Pembrolizumab (200 mg) will be administered on days 1, 43, 64, 85. Subjects who have measurable disease outside of the radiation field and who have derived benefit from the 4 doses of pembrolizumab may continue to receive pembrolizumab every 3 weeks for up to 2 years. HDCRT will be administered to the primary tumor and/or sites of metastatic disease (1 or more sites permitted) over a period of 3-5 days. The length of time for administration of the HDCRT will depend on the site of disease that is to be radiated. HDCRT will begin on day 1.

Radiation: High-Dose Conformal Radiation TherapyDrug: Pembrolizumab
Arm B: HDCRT administered between doses 1& 2 of pembrolizumabexperimental

Pembrolizumab (200 mg) begins on day 1. HDCRT (24 Gy in 3 fractions of 8 Gy each for bone and/or soft tissue lesions; 30 Gy in 5 fractions of 6 Gy each for the prostate gland) begins on day 22. Pembrolizumab (200 mg) will be administered on days 1, 43, 64, 85. Subjects who have measurable disease outside of the radiation field and who have derived benefit from the 4 doses of pembrolizumab may continue to receive pembrolizumab every 3 weeks for up to 2 years. HDCRT will be administered to the primary tumor and/or sites of metastatic disease (1 or more sites permitted) over a period of 3-5 days. The length of time for administration of the HDCRT will depend on the site of disease that is to be radiated. HDCRT will begin on day 22.

Radiation: High-Dose Conformal Radiation TherapyDrug: Pembrolizumab
Arm C: HDCRT administered prior to first dose of pembrolizumabexperimental

Pembrolizumab (200 mg) begins on day 1. HDCRT (24 Gy in 3 fractions of 8 Gy each for bone and/or soft tissue lesions; 30 Gy in 5 fractions of 6 Gy each for the prostate gland) begins on day 1. Pembrolizumab will be administered on days 22, 43, 64, and 85. Subjects who have measurable disease outside of the radiation field and who have derived benefit from the four doses of pembrolizumab may continue to receive pembrolizumab every 3 weeks for up to 2 years. HDCRT will be administered to the primary tumor and/or sites of metastatic disease (1 or more sites permitted) over a period of 3-5 days. The length of time for administration of the HDCRT will depend on the site of disease that is to be radiated. HDCRT will begin on day 1.
