I. To assess the response rate of nivolumab alone and in combination with ipilimumab in subjects with metastatic or locally advanced/unresectable gastrointestinal stromal tumor (GIST).
I. Ascertain the response rate of nivolumab alone and in combination of ipilimumab in subjects with metastatic or locally advanced/unresectable GIST by Choi criteria.
II. Assess the progression-free survival (PFS). III. Ascertain the clinical benefit rate (CBR = complete response [CR] + partial response [PR] and stable disease [SD]) of nivolumab and ipilimumab in refractory/unresectable GIST.
IV. Explore the safety of nivolumab monotherapy and nivolumab and ipilimumab in this population assessed by the frequency and severity of adverse events (AEs).
I. Compare RR and CBR in patients whose tumors are programmed cell death ligand 1 (PD-L1) positive (+) and PD-L1 negative (-) at baseline.
II. In the patients who are PD-L1 positive, compare RR and CBR in patients with 1% and 5% tumor membrane staining.
III. Determine the baseline mutational load of patients at the start of treatment.
IV. Determine the response to treatment based on the baseline mutation load and baseline GIST mutations.
V. Determine the response rate based on GIST mutational status.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive nivolumab intravenously (IV) over 60 minutes on day 1. Courses repeat every 14 days for up to 2 years in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive nivolumab IV over 30 minutes on day 1 and ipilimumab IV over 30 minutes every 6 weeks. Courses repeat every 14 days for up to 2 years in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up periodically.

Other: Laboratory Biomarker Analysis
- Overall response rate defined as the number of subjects with a best objective response of confirmed CR or PR divided by the number of subjects [ Time Frame: Up to 2 years ]Will utilize an exact binomial test to compare the RECIST response rate separately within each of the two study arms. Additionally, an exact 95% confidence interval will be constructed within each arm.
- Clinical benefit rate [ Time Frame: Up to 2 years ]The endpoint will utilize an exact binomial test to compare the RECIST response rate separately within each of the two study arms. Additionally, an exact 95% confidence interval will be constructed within each arm.
- Frequency and severity of AEs assessed by NCI CTCAE v 4.03 [ Time Frame: Up to 2 years ]Will be tabulated by type, severity, and the proportion of subject experiencing the event. Fisher's exact tests will be used to compare the AE rates between groups for each category of AE and compute exact 95% confidence intervals for the rates of AEs.
- Progression free survival time [ Time Frame: Up to 2 years ]Time to disease progression will be plotted using Kaplan-Meier curves and compared between groups with log-rank tests.
- Response rate by Choi criteria [ Time Frame: Up to 2 years ]Will utilize an exact binomial test to compare the response rate separately within each of the two study arms. Additionally, an exact 95% confidence interval will be constructed within each arm.

- This study permits the re-enrollment of a subject that has discontinued the study as a pre-treatment failure (i.e., subject has not been randomized / has not been treated); if re-enrolled, the subject must be re-consented
- Adequate archival tissue must be available from the prior 3 months to signing consent; if not, an adequate tumor specimen obtained by either excisional biopsy, incisional biopsy or core needle biopsy must be sent to the central pathology lab for evaluation; the material must measure at least 0.8 × 0.1 cm in size or contain at least 100 tumor cells
