Description

Summary

This pilot phase I/II trial studies the side effects and best dose of olaparib when given together with ramucirumab and how well they work in treating patients with gastric or gastroesophageal junction cancer that has spread to other places in the body, has come back, or cannot be removed by surgery. Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as ramucirumab, may interfere with the ability of tumor cells to grow and spread. Giving olaparib and ramucirumab may work better in treating patients with gastric or gastroesophageal junction cancer.

Official Title

A Phase 1/2 Study of Olaparib in Combination With Ramucirumab in Metastatic Gastric and Gastroesophageal Junction Adenocarcinoma (10017760)

Details

PRIMARY OBJECTIVES:

  1. To determine the safe dose of olaparib with ramucirumab, but not to exceed olaparib dose of 300 mg twice daily (tablet formulation). (Phase I) II. To determine the efficacy of olaparib plus ramucirumab as measured by the objective response rates (ORR) stratified by BROCA-HR biomarker status. (Phase II).

SECONDARY OBJECTIVES:

  1. To estimate median progression-free survival (PFS) stratified by BROCA-HR biomarker status.

II. To estimate median overall survival (OS) stratified by BROCA-HR biomarker status.

III. To measure the prevalence of the BROCA-HR biomarker in our study population.

IV. To determine toxicity of olaparib and ramucirumab combination.

TERTIARY OBJECTIVES:

  1. To assess the correlation between the signature 3 status, and mutations in BROCA-HR panel.

II. To evaluate the association between findings from BROCA-HR panel with response to therapy.

III. To evaluate the association between findings from BROCA-HR panel and signature 3 results with response to therapy.

IV. To determine results of immunoassay for poly-ADP-ribosylated (PAR) substrates in tumor tissue.

  1. To create a PDX model to study deoxyribonucleic acid (DNA) repair in gastric tumors treated with PARP inhibitors (PARPi) from both pre-treatment biopsy and repeat biopsy after 16 weeks of treatment.

VI. Development of a novel genomic assay for BRCAness VII. Defining T cell receptor diversity of gastric cancer patients +/- BRCAness VIII. Biobank additional tumor tissue for future genomic analysis. IX. Biobank peripheral blood for future genomic analysis and assessment of circulating tumor DNA.

OUTLINE: This is a phase I, dose-escalation study of olaparib followed by a phase II study.

Patients receive olaparib orally (PO) twice daily (BID) on days 1-14 and ramucirumab intravenously (IV) over 60 minutes on day 1. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 4 weeks and then every 3-6 weeks thereafter.
