I. To demonstrate that neoadjuvant nivolumab and ipilimumab in combination with short-course radiation will improve the pathologic complete response rate (pCR) in microsatellite instability-high (MSI-H)/mismatch repair deficiency (dMMR) locally advanced rectal adenocarcinoma at total mesorectal excision (TME).
I. To demonstrate that neoadjuvant nivolumab and ipilimumab in combination with short-course radiation will improve the rate of sphincter preservation in low-lying tumors.
II. To demonstrate that neoadjuvant nivolumab and ipilimumab in combination with short-course radiation will improve 5-year disease-free survival (DFS).
III. To demonstrate that neoadjuvant nivolumab and ipilimumab in combination with short-course radiation will improve overall survival (OS).
IV. To demonstrate that neoadjuvant nivolumab and ipilimumab in combination with short-course radiation will have acceptable safety/toxicity.
Patients receive nivolumab intravenously (IV) over 30 minutes and ipilimumab IV over 90 minutes on day 1. Treatment repeats every 28 days for 2 cycles. Starting least 2 weeks but no longer than 6 weeks after completion of cycle 2 of nivolumab and ipilimumab, patients undergo short-course radiation therapy of 5 fractions daily for 1 week. Patients then continue to receive nivolumab IV over 30 minutes and ipilimumab IV over 90 minutes on day 1. Treatment repeats every 28 days for 2 cycles in the absence of disease progression or unacceptable toxicity. 8-12 weeks after completion of 4th cycle of nivolumab and ipilimumab, patients undergo TME. Patients also undergo MRI and CT prior to TME and during follow up, and undergo sigmoidoscopy prior to TME.
After completion of study treatment, patients are followed up for 5 years.

Experimental: Treatment (nivolumab, ipilimumab, radiation therapy, TME)
Patients receive nivolumab IV over 30 minutes and ipilimumab IV over 90 minutes on day 1. Treatment repeats every 28 days for 2 cycles. Starting least 2 weeks but no longer than 6 weeks after completion of cycle 2 of nivolumab and ipilimumab, patients undergo short-course radiation therapy of 5 fractions daily for 1 week. Patients then continue to receive nivolumab IV over 30 minutes and ipilimumab IV over 90 minutes on day 1. Treatment repeats every 28 days for 2 cycles in the absence of disease progression or unacceptable toxicity. 8-12 weeks after completion of 4th cycle of nivolumab and ipilimumab, patients undergo TME. Patients also undergo MRI and CT prior to TME and during follow up, and undergo sigmoidoscopy prior to TME.

Inhaled or topical steroids and adrenal replacement doses < 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease. Patients are permitted to use topical, ocular, intra-articular, intranasal, and inhalational corticosteroids (with minimal systemic absorption). Physiologic replacement doses of systemic corticosteroids are permitted, even if < 10 mg/day prednisone equivalents. A brief course of corticosteroids for prophylaxis (e.g., contrast dye allergy) or for treatment of non-autoimmune conditions (e.g., delayed-type hypersensitivity reaction caused by contact allergen) is permitted
- Patient must not be pregnant or breast-feeding due to the potential harm to an unborn fetus and possible risk for adverse events in nursing infants with the treatment regimens being used. All patients of childbearing potential must have a blood test or urine study within 2 weeks prior to registration to rule out pregnancy. A repeat pregnancy test must be done within 72 hours prior to first dose of treatment if the baseline test was done outside the 72 hour window. A patient of childbearing potential is defined as anyone, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria: 1) has achieved menarche at some point, 2) has not undergone a hysterectomy or bilateral oophorectomy; or 3) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months)
- Patient must not have had live vaccines within 30 days prior to registration. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, chicken pox, yellow fever, rabies, Bacillus Calmette-Guerin (BCG), and typhoid (oral) vaccine. Patients are permitted to receive inactivated vaccines and any non-live vaccines including those for the seasonal influenza and COVID-19 (Note: intranasal influenza vaccines, such as Flu-Mist are live attenuated vaccines and are not allowed). If possible, it is recommended to separate study drug administration from vaccine administration by about a week (primarily, in order to minimize an overlap of adverse events)
