A Phase II Study of Olaparib in Patients With Advanced Biliary Tract Cancer With Aberrant DNA Repair Gene Mutations

Description

This phase II trial studies how well olaparib works in treating patients with biliary tract cancer that has spread to other places in the body (metastatic) and with aberrant DNA repair gene mutations. Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.PRIMARY OBJECTIVES: I. To determine the efficacy (progression free survival \[PFS\] rate at first scan) of olaparib monotherapy in advanced biliary tract cancer (BTC) with mutations in deoxyribonucleic acid (DNA) repair genes. SECONDARY OBJECTIVES: I. To determine the overall survival of patients with advanced biliary tract cancer with mutations in DNA repair genes treated with olaparib. II. To determine the progression free survival of patients with advanced biliary tract cancer with mutations in DNA repair genes treated with olaparib. III. To determine the objective response of patients with advanced biliary tract cancer with mutations in DNA repair genes treated with olaparib. IV. T
