Summary:

      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.

          -  Pre-clinical data indicate that olaparib can have adverse effects on embryofetal
             survival and development. It is further not known whether olaparib or its metabolites
             are found in seminal fluid. For these reasons:

          -  Women of childbearing potential and their partners, who are sexually active, must
             agree to the use of 2 highly effective forms of contraception in combination (male
             condom plus one other method or must totally/truly abstain from any form of sexual
             intercourse. This should be started from the signing of the informed consent,
             throughout their participation in the study and for at least 1 month after the last
             dose of olaparib.

          -  Male patients must use a condom during treatment and for 3 months after the last dose
             of olaparib when having sexual intercourse with a pregnant woman or with a woman of
             childbearing potential. Female partners of male patients should also use a highly
             effective form of contraception if they are of childbearing potential. Male patients
             should not donate sperm throughout the period of taking olaparib and for 3 months
             following the last dose of olaparib.

          -  Acceptable birth control methods:

               -  Total sexual abstinence i.e., refrain from any form of sexual intercourse in line
                  with the patients usual and/or preferred lifestyle. Abstinence must be for the
                  total duration of the study treatment and for at least 1 month (for female
                  patients) or 3 months (for male patients) after the last dose of study treatment.
                  Periodic abstinence (e.g., calendar ovulation, symptothermal, post-ovulation
                  methods) and withdrawal are not acceptable methods of contraception.

               -  Vasectomised sexual partner PLUS male condom. With participant assurance that
                  partner received post-vasectomy confirmation of azoospermia.

             gastrointestinal disorders likely to interfere with absorption of the study
             medication.

          -  Patients considered a poor medical risk due to a serious, uncontrolled medical
             disorder, non-malignant systemic disease or active, uncontrolled infection. Examples
             include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within 3

             that prohibits obtaining informed consent.

          -  Pregnant women are excluded from this study because olaparib has the potential for
             teratogenic or abortifacient effects. Women must either be post-menopausal or must
             have a negative pregnancy test (urine or serum) less than or equal to 28 days prior to
             enrollment and confirmed on day 1 of cycle 1 of study therapy. Postmenopausal is
             defined as:

        Amenorrheic for 1 year or more following cessation of exogenous hormonaltreatments

        chemotherapy-induced menopause with >1-year interval since last menses

        surgical sterilisation (bilateral oophorectomy or hysterectomy)

          -  Because there is an unknown but potential risk for adverse events in nursing infants
             secondary to treatment of the mother with olaparib, breastfeeding should be
             discontinued if the mother is treated with olaparib.

          -  Immunocompromised patients are excluded.

          -  Patients who are known to be serologically positive for human immunodeficiency virus
             (HIV). This includes HIV patients on antiretroviral therapy due to the potential for
             pharmacokinetic interactions with olaparib.

          -  Patients with known active hepatitis (i.e. Hepatitis B or C) due to risk of
             transmitting the infection through blood or other body fluids

          -  Previous allogeneic hematopoietic stem cell transplant, allogeneic bone marrow
             transplant or double umbilical cord blood transplant (duCBT)
