Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Patient must have a histologic or cytologic diagnosis of pancreatic adenocarcinoma. Patients with neuroendocrine tumors, acinar cell and adenosquamous carcinomas are excluded. All disease must be assessed and documented on the Baseline Tumor Assessment Form

Patients must be >= 18 years old

Timeline

Screening 3 weeks

Awards & highlights

No Placebo-Only Group

Summary

This trial is testing whether adding pembrolizumab to olaparib, which is the standard of care, is more effective in treating patients with metastatic pancreatic cancer who have BRCA1 or BRCA2 mutations.

Who is the study for?

This trial is for adults with metastatic pancreatic cancer who have inherited BRCA mutations. They must have completed first-line platinum-based chemotherapy, show stable or responding disease, and not be on certain drugs that affect olaparib. People with HIV or hepatitis C can join if treated and virus-free. Those with a history of severe lung inflammation, active infections, autoimmune diseases needing recent treatment, or other cancers that could interfere are excluded.

What is being tested?

The study is testing if adding pembrolizumab (an immunotherapy drug) to olaparib (a PARP inhibitor used as standard care) is more effective in treating patients whose pancreatic cancer has spread and have BRCA1/2 mutations. It's a phase II trial where the effectiveness of this combination will be compared to using olaparib alone.

What are the potential side effects?

Possible side effects include immune system reactions leading to inflammation in various organs, infusion-related reactions from pembrolizumab, fatigue, nausea from both drugs; blood cell count changes; increased risk of infection; potential harm to unborn babies necessitating contraception.

Experimental Treatment

Active Control

Group I: Arm A (olaparib, pembrolizumab)Experimental Treatment6 Interventions

Patients receive olaparib PO BID on days 1-21 and pembrolizumab IV over 30 minutes on day 1 of each cycle. Treatment repeats every 21 days for up to 18 cycles in the absence of disease progression or unacceptable toxicity. Beginning in cycle 19, patients receive olaparib PO BID on days 1-42 and pembrolizumab IV over 30 minutes on day 1 of each cycle. Cycles repeat every 42 days in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan or MRI, tumor biopsy and blood sample collection throughout the study.

Group II: Arm B (olaparib)Active Control5 Interventions

Patients receive olaparib PO BID on days 1-21 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan or MRI, tumor biopsy and blood sample collection throughout the study.
