Official title

Phase II Study of Olaparib in Subjects With Malignant Mesothelioma

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Background: The drug olaparib may stop cancer cells from fixing damage to their deoxyribonucleic acid (DNA). It has been approved to treat certain cancers in people that were born with a mutation in the breast cancer (BRCA) gene. It has not been approved for treating mesothelioma. But some people with mesothelioma have mutations in a gene, BRCA1 Associated Protein 1 (BAP1) related to BRCA. Researchers want to see if olaparib can work in patients with mutations in this gene. They also want to see if works on mutations in other genes or patients without any mutations. They want to see if olaparib causes mesothelioma tumors to shrink. Objective: To study the effect of olaparib on mesothelioma. Eligibility: People ages 18 and older with malignant mesothelioma that has already been treated Design: Participants will be screened with Sample of tumor tissue or fluid Medical history Physical exam Blood, heart, and urine tests Scans and x-rays Participants will give blood and tissue samples. These will be genetically tested. The study will be done in 21-day cycles. Participants will take tables of the study drug 2 times each day. They will get information on what food and drugs to avoid during the study. They will get information about birth control. They will keep a diary of doses and symptoms. Participants will have blood and urine tests and scans every few weeks. Participants will be told any important genetic testing results. Participants will stay in the study until their disease gets worse or the participant or their doctor chooses to stop it. About 30 days after stopping the study drug, participants will have a follow-up visit. They will have a medical history, physical exam, blood tests, and scans. Some participants will continue to have scans every 6 weeks. ...
