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

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.

PRIMARY OBJECTIVES:

I. 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:

I. 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:

I. 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.

V. 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.
