Experimental: CBI plus SBRT
Checkpoint blockade immunotherapy (CBI) plus stereotactic body radiation therapy (SBRT)
|
Radiation: CBI plus SBRT
SBRT at 28.5 Gy (9.5 Gy x3 fractions) will be delivered within 1 - 21 days of the start of Cycle 1 of the CBI plus CBI (approved CBIs including anti-CTLA-4 and anti-PD-1/PD-L1 antibodies) |
Active Comparator: CBI
Checkpoint blockade immunotherapy (CBI)
|
Drug: CBI
Approved CBIs (including anti-CTLA-4 and anti-PD-1/PD-L1 antibodies) |
- Objective Response Rate [ Time Frame: Responses measured by RECIST at 16 weeks from baseline ]Complete response plus partial response
- Safety and toxicity of combined CBI plus SBRT [ Time Frame: Evaluated at each treatment cycle (each cycle is 2 or 3 weeks), then at 8 weeks, 16 weeks, 6 months, 12 months, 18 months, and 24 months, then every 6 months up to 2 years ]Adverse events assessed from time of first dose to treatment completion (approximately 1 year)
- Progression Free Survival [ Time Frame: Assessed at 5 years ]The time from starting treatment to the time of first documented tumor progression or death due to any cause, whichever occurs first
- Overall Survival [ Time Frame: Assessed at 5 years ]The time from starting treatment until death due to any cause.
- Rate of Stable Disease [ Time Frame: Assessed at 5 years ]The rates of stable disease great than or equal to 6 months during and after SBRT in combination with CBI compared to CBI alone.
- Change in anti-tumor immune response [ Time Frame: At week 3 or 4 after starting treatment (prior to Cycle 2 of CBI) and at 2 months. Each cycle is 2 or 3 weeks. ]

Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Patient has one lesion that is treatable with SBRT.
- Patient has at least 1 site of measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria on computed tomography (CT) or Magnetic resonance imaging (MRI) which will not be irradiated.
- Histological confirmation of malignancy (primary or metastatic tumor).
- Patient may have any prior therapy allowed aside from having had prior radiotherapy to the treatment site.
- Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2.
- Patient's screening laboratory values must meet protocol limits.
- Patient must have the ability to understand and the willingness to sign a written informed consent document.
Exclusion Criteria:
- Patient has had chemotherapy or radiotherapy within 4 weeks prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier.
- Patient receiving any investigational or experimental agents other than immunotherapy.
- Patient who has had any prior radiotherapy to the treatment site(s).
- Patient is a pregnant woman (pregnant women are excluded from this study because radiation treatment has known potential for teratogenic or abortifacient effects).
- Patient refuses to sign informed consent.
