Brief Summary:
This research is being done to see how the combination of dostarlimab, niraparib, and radiation therapy works in controlling metastatic pancreatic cancer.

Condition or disease Intervention/treatment Phase
Pancreatic Cancer Metastatic Pancreatic Cancer Drug: Niraparib Drug: Dostarlimab Radiation: Radiation Phase 2

Detailed Description:

This two-stage single arm phase II trial will evaluate the efficacy of niraparib with dostarlimab and radiation therapy in patients with metastatic pancreatic cancer

The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits.

The names of the experimental interventions involved in this study are:

  • Dostarlimab
  • Niraparib
  • Radiation Therapy

It is expected that about 25 people will take part in this research study. An initial 15 participants will be enrolled during the first stage and evaluated for treatment disease control, if none of the initial 15 participants achieve disease control the study will be terminated.

It is expected participants will be on the research study for as long as the experimental interventions are safe, and their metastatic pancreatic cancer does not progress with up to 5 years of follow up after participants stop taking the experimental interventions.

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational intervention to learn whether the intervention works in treating a specific disease. "Investigational" means that the intervention is being studied.

The U.S. Food and Drug Administration (FDA) has not approved dostarlimab as a treatment for any disease. Dostarlimab is a type of antibody (a protein that attaches to other cells to fight off infection) that is believed to work by attaching to a protein called PD-1 on Tcells.

This PD-1 protein controls parts of the immune system (the system in the body that fights off infections and diseases) by shutting down certain immune responses responsible for recognizing and destroying cancer cells. The investigators believe that dostarlimab will inhibit the PD-1 protein, thus allowing the immune cells to recognize and destroy cancer cells. The FDA has not approved niraparib for metastatic pancreatic cancer, but it has been approved for other uses. Niraparib is a type of drug called a "PARP inhibitor", which blocks DNA (the genetic material of cells) damage from being repaired or may prevent damage from occurring in the first place. In cancer treatment, inhibiting PARP may help kill cancer cells by not allowing the cancer cells to repair its DNA damage or prevent DNA damage from occurring. It is believed that the combination of dostarlimab, niraparib, and radiation therapy may have a greater effect on metastatic pancreatic cancer cells than when these interventions are used alone.

Participants with ≤ grade 2 neuropathy are an exception to these criteria and may qualify for the study. If the participant received major surgery, then they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.
  • Received investigational therapy ≥ 4 weeks, or within a time interval less than at least 5 half-lives of the investigational agent, whichever is shorter, prior initiating protocol therapy.

Inhaled or topical steroids and adrenal replacement doses > 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease. Participants are permitted to use topical, ocular, intraarticular, 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.
  • Known history of active TB (Bacillus Tuberculosis). Testing is not required for eligibility purposes.
  • Known hepatitis B virus surface antigen (HBV sAg) or hepatitis C virus ribonucleic acid (HCV antibody) indicating acute or chronic infection. Testing is not required for eligibility purposes.
  • Known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS). These participants are at increased risk of lethal infections when treated with marrow suppressive therapy. Testing is not required for eligibility purposes.
  • Known ≥ Grade 3 immune-related AE with prior immunotherapy, with the exception of non-clinically significant lab abnormalities.
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, recent (within 90 days) myocardial infarction or psychiatric illness/social situations that would limit compliance with study requirements.

  • Known history of, or any evidence of active, non-infectious pneumonitis or interstitial lung disease.
  • Active infection requiring systemic therapy
  • Has received a live vaccine within 30 days of planned start of study therapy. Note:

Seasonal influenza vaccines for injection are generally inactivated flu vaccines and are allowed; however intranasal influenza vaccines (e.g., Flu-Mist®) are live attenuated vaccines, and are not allowed.

  • Known hypersensitivity to niraparib and dostarlimab components or excipients.
  • History of severe hypersensitivity reaction to any monoclonal antibody
  • Participants with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.

Further imaging is not required for eligibility purposes.
