Intervention / Treatment
Detailed Description
Standard of care therapy for resectable locally advanced rectal cancer includes pelvic radiation (short or long course), chemotherapy, and (if indicated) surgery.
In this study, participants will:
- Take niraparib by mouth once daily for up to 12 weeks.
- Receive radiation therapy once daily for five days (Monday through Friday).
- Receive intravenous (IV) dostarlimab once every three weeks for up to 12 weeks.
- Provide feedback about how they feel and their quality of life. This is done through short surveys as well as discussing with the study team.
- Undergo a sigmoidoscopy (i.e. scope of the tumor) and biopsy about halfway through treatment
- Provide tumor tissue and blood samples for analysis

- Serum creatinine > 1.5 x upper limit of normal (ULN) or calculated creatinine clearance 60mL/min using the Cockcroft-Gault equation
- Total bilirubin > 1.5 x ULN (>2.0 x ULN in patients with known Gilberts syndrome) or direct bilirubin > 1 x ULN
- Aspartate aminotransferase and alanine aminotransferase > 2.5 x ULN
- International normalized ratio (INR) or prothrombin time (PT) >1.5× ULN unless patient is receiving anticoagulant therapy as long as PT or partial thromboplastin (PTT) is within therapeutic range of intended use of anticoagulants.
- Activated partial thromboplastin time (aPTT) >1.5× ULN unless patient is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants
- Uncontrolled arterial hypertension, i.e. systolic BP > 140 mmHg, diastolic BP > 90 mmHg.

- Presence of any M1 metastatic lesions.
- Prior pelvic radiotherapy
- Indication for total neoadjuvant therapy or alternative radiation regimen

- Active Crohn's disease or another inflammatory bowel disease
- Any T or N stage disease that is deemed unresectable by colorectal surgery without neoadjuvant therapy
- Prior anti-PD-L1 therapy, PARPi therapy, or known germline BRCA-1/2 mutation as patients with germline BRCA-1/2 mutations have an increased risk of severe normal tissue injury to combination radiation and PARP inhibition.
- Received a live vaccine within 14 days of initiating protocol therapy.
- Received colony stimulating factors (e.g., granulocyte colony-stimulating factor, granulocyte macrophage colony stimulating factor, or recombinant erythropoietin) within 4 weeks prior to Day 1 of protocol therapy.
- Major surgery within 3 weeks prior to Day 1 of protocol therapy (participant must recover from any surgical effects).

- Known history of myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML)
- Diagnosis, detection, or treatment of another type of cancer ≤ 2 years prior to initiating protocol therapy (except basal or squamous cell carcinoma of the skin and cervical cancer that has been definitively treated).
- Known history of ≥ grade 3 immune-related AE with prior immunotherapy, with the exception of non-clinically significant lab abnormalities.
- Diagnosis of immunodeficiency or has received systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to initiating protocol therapy.
- Patients with known HIV who have documented detectable viral load or patients with a documented undetectable viral load and a CD 4 count < 350 cells within 6 months of study treatment day
- Known active hepatitis B (e.g., hepatitis B surface antigen [HBsAg] reactive) or hepatitis C (e.g., hepatitis C virus [HCV] ribonucleic acid [qualitative] is detected).
- Active autoimmune disease that has required systemic treatment in the past 2 years (i.e., with use of disease-modifying agents, corticosteroids, or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
- History of interstitial lung disease.
- Active or uncontrolled infection necessitating hospitalization or treatment delay.
- Known serious, uncontrolled medical disorder or nonmalignant systemic disease that preclude eligibility to undergo low anterior resection (LAR). Examples include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within 90 days) myocardial infarction, uncontrolled major seizure disorder, or any psychiatric disorder that prohibits obtaining informed consent
Pregnancy. Participant must have a negative serum pregnancy test within 72 hours prior to taking study treatment if of childbearing potential and agrees use a highly effective method of contraception from screening through 180 days after the last dose of niraparib and after the last dose of dostarlimab, or is of nonchildbearing potential. Nonchildbearing potential is defined as follows (by other than medical reasons):
- ≥ 60 years of age
- Post-hysterectomy. Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by an ultrasound.
- Actively breastfeeding. Participant must agree to not breastfeed during the study or for 8 weeks after the last dose of study treatment.
- Declines to use a highly effective method of contraception (see Section 5.2.1 for a list of acceptable birth control methods). Eligible patients must agree to highly effective methods of contraception starting with the first dose of study treatment through 180 days after the last dose of niraparib and dostarlimab.
