Rucaparib and Ramucirumab with or without Nivolumab for the Treatment of Stage III-IV Gastric, Esophageal, or Esophageal Adenocarcinoma

Trial Status: Active

This phase I / II trial studies the best dose of rucaparib and how well rucaparib, ramucirumab with or without nivolumab work in treating patients with stage III-IV gastric, esophageal, or esophageal adenocarcinoma. Rucaparib may help block a protein that helps repair deoxyribonucleic acid (DNA) (genetic makeup) when it becomes damaged. This action may keep cancer cells from repairing their damaged DNA and causing them to die. Ramucirumab and nivolumab together may help to block the blood supply to the tumor and help the immune system discover and attack cancer cells. Giving rucaparib, ramucirumab, and nivolumab may provide a better treatment for gastric, esophageal, and esophageal adenocarcinoma compared to rucaparib and ramucirumab alone.

PHASE I: Patients receive rucaparib orally (PO) twice daily (BID) on days 1-28, ramucirumab intravenously (IV) over 60 minutes on days 1 and 15, and nivolumab IV over 30 minutes on day 1. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity.

PHASE II: Patients are assigned to 1 of 2 cohorts.

COHORT A: Patients receive rucaparib, ramucirumab and nivolumab as in Phase I. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity.

COHORT B: Patients receive rucaparib PO BID on days 1-28 and ramucirumab IV over 60 minutes on days 1 and 15. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity.
