This phase I/II trial studies the side effects of anti-CTLA4-NF monoclonal antibody (mAb) (BMS986218), nivolumab, and stereotactic body radiation therapy in treating patients with solid malignancies that has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as anti-CTLA4-NF mAb (BMS-986218) and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Giving -CTLA4-NF mAb (BMS986218), nivolumab, and stereotactic body radiation therapy may kill more tumor cells.



I. To evaluate the safety profile of intravenous anti-CTLA4 monoclonal antibody BMS-986218 (anti-CTLA4-NF mAb [BMS-986218]) alone or with nivolumab administered in combination with stereotactic body radiation therapy (SBRT) targeting 1-4 lesion(s) for patients with metastatic cancers.


I. To determine antitumor activity of anti-CTLA4-NF mAb (BMS-986218) therapy with SBRT treatment for 1-4 lesions in non-irradiate tumors (abscopal lesions; out of external beam radiation [XRT] field) as defined by Immune-Related Response Criteria (irRC).

II. To determine antitumor activity of anti-CTLA4-NF mAb (BMS-986218) therapy with RadScopal treatment in the low dose treated lesion as defined by irRC.

III. To evaluate treatment efficacy in different SBRT treatment sites (liver versus [vs.] adrenal, lung vs. adrenal).

IV. To evaluate treatment efficacy by comparing anti-CTLA4-NF mAb (BMS-986218) alone with SBRT treatment vs. anti-CTLA4-NF mAb (BMS-986218) in combination with nivolumab and SBRT treatment.


I. To evaluate treatment efficacy by comparing anti-CTLA4-NF mAb (BMS-986218) alone or with SBRT treatment vs. ipilimumab alone or with SBRT treatment (previous trial).

II. To evaluate the associations of tumor-associated and systemic immune biomarkers for therapy with clinical response outcomes and toxicity prediction.

III. To evaluate whether skeletal mass, neutrophil, neutrophil to lymphocyte ratio, and tumor bulk are correlated with clinical outcomes and adverse events.

IV. To evaluate whether tumor kinetics in combination with clinical correlates can help determine treatment response.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive anti-CTLA4 monoclonal antibody BMS-986218 intravenously (IV) over 30 minutes on day 1. Treatment repeats every 28 days for 4 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo SBRT on days 36-39 (days 8-11 of cycle 2).

ARM II: Patients receive anti-CTLA4 monoclonal antibody BMS-986218 and SBRT as in Arm 1. Beginning cycle 2, patients also receive nivolumab IV over 30 minutes starting on day 1. Cycles repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 and 60 days and 6 and 12 months after last cycle of anti-CTLA4 monoclonal antibody BMS-986218.

Patients must have histological confirmation of solid metastatic cancer with at least one metastatic or primary lesion in the bone, adrenal, liver or lung/chest
Patients who have completed prior systemic anti-cancer therapies, an interval of 5 drug half-lives or 4-weeks whichever is shorter, is required, prior to enrollment on study. Note: patients with anaplastic thyroid carcinoma will be waived from this inclusion criteria given the rapid trajectory of their disease. In addition, patients with metastatic castration-resistant prostate cancer (CRPC) will be allowed to continue their maintenance therapy with gonadotropin-releasing hormone (GnRH) analogue agents and supportive bone therapy (e.g., denosumab [XGEVA], zoledronic acid [Zometa])
All patients must have at least one metastatic or primary lesion within the bone, lung/chest, liver or adrenal located in an anatomical location amenable to radiation treatment with either 50 Gy in 4 fractions, 60 Gy in 10 fractions, or 30 Gy in 5 fx. Patients may not have more then 80% liver displaced with cancer
Repeat radiation in fields previously radiated will be allowed at the discretion of the treating physician
Age >= 18 years
Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin) within 24 hours prior to the start of study treatment. Subjects of childbearing potential are those who have not been surgically sterilized or have not been in postmenopausal state. Females in postmenopausal state under the age of 55 years must have a serum follicle stimulating hormone, (FSH) level > 40 mIU/mL to confirm menopause
Women must not be breastfeeding for the duration of the study and 105 days AFTER completion of study treatment for BMS-986218 monotherapy treatment, 155 days AFTER completion of combination therapy (BMS-986218 + nivolumab) or 5 months AFTER completion of nivolumab maintenance treatment
WOCBP receiving monotherapy or combination therapy treatment with BMS-986218 must agree to follow instructions for method(s) of contraception or be surgically sterile, or abstain from heterosexual activity for the duration of the study and 105 days AFTER completion of study treatment for BMS-986218 monotherapy treatment, 155 days AFTER completion of combination therapy (BMS-986218 + nivolumab) or 5 months AFTER completion of nivolumab maintenance treatment. WOCBP who are continuously not heterosexually active are exempt from contraceptive requirements, but should still undergo pregnancy testing as described in this section. In the case of male participants, during the course of treatment and 165 days AFTER the end of BMS-986218 monotherapy treatment or 215 days AFTER the end of combination therapy treatment (BMS-986218 + nivolumab) or 7 months AFTER completion of nivolumab maintenance treatment the participant should not father a child (condom use is mandatory, even if vasectomized) or donate sperm. Local laws and regulations may require use of alternative and/or additional contraception methods
Male participants who are sexually active with WOCBP must agree to follow instructions for methods of contraception during monotherapy treatment with BMS-986218 plus 5 half-lives (75 days) of BMS-986218 plus 90 days for a total of 165 days after the end of BMS-986218 monotherapy treatment or 215 days after the end of combination therapy treatment (BMS-986218 + nivolumab), or 7 months AFTER completion of nivolumab maintenance treatment. In addition, male participants must be willing to refrain from sperm donation during this time
