Phase II Trial of Olaparib in Homologous Recombination Deficient (HRD) Malignant Mesothelioma
In this study, researchers will give olaparib (a drug) to mesothelioma patients who have specific changes in their DNA (known as gene mutations). Researchers will give this drug to each patient on the study to find out if it will help the patient's tumor shrink or stop growing.

Inclusion Criteria:
- Must have a medical diagnosis of malignant mesothelioma that has been confirmed by a
physician.
- Participant must be able to sign a consent form stating that they choose (of their
own free will) to participate in the study and agree to follow the study
requirements and restrictions that are listed in the consent form.
- Must be willing to sign and date consent form before any mandatory study-specific
procedures, sample collecting and tests.
- Willing to experience genetic testing to determine study eligibility. Must be
willing to genetically test tumor and normal body cells.
- Before participating in the treatment phase of this study, participants must be
willing to give their own consent (agreement) to have their samples collected for
genetic and biomarker research.
- Age 18 or older.
- Participant must show evidence of specific DNA changes/genetic mutations defined as
follows: A) BAP1 loss (the loss of a protein called ubiquitin carboxyl-terminal
hydrolase) verified by physicians at the University of Chicago using sampling tests
AND/OR B) A mutation (abnormal change) in the participant's germ cells (reproductive
cells) or somatic cells (non-reproductive cells) that disrupts protein function in
at least one of the patient's genes.
- Prior treatment with cisplatin or carboplatin is required.
- Patients must have platinum-sensitive disease (cancer that responds to treatments
with anticancer drugs containing metal platinum). For eligibility in this study,
platinum-sensitive disease will be defined as no disease progression while on a
platinum agent (chemotherapy drug) or for at least 3 months after completing
treatment with a platinum agent.
- Patients must have normal organ and bone marrow function measured within 28 days
prior to receiving study treatment. Normal bone marrow and organ function will be
assessed using specific lab tests/ criteria set by the study's lead physician.
- Eastern Cooperative Oncology Group (ECOG) performance status 0-1.
- Patients must have a life expectancy of 16 weeks or more.
- Must have a tumor that can be measured according to criteria set by the modified
Response Evaluation Criteria in Solid Tumors (RECIST) standards for pleural
mesothelioma and RECIST 1.1 for peritoneal and tunica vaginalis mesothelioma.
Patients in the study must have at least one area of damaged tissue (a lesion) that
has not received previous radiation treatment. This damaged tissue must be
accurately measured at the beginning of the study as greater than or equal to 10 mm
in the longest diameter (except lymph nodes which must have short axis greater than
or equal to 15 mm). The patient's tumor would be measured using computed tomography
(CT), which is suitable for accurate repeated measurements.
- Both male and female patients can participate in this study.
- If a woman is of childbearing potential and wishes to participate in the study, she
most show evidence that she is not pregnant using a negative urine or serum
pregnancy test within 28 days of study treatment and confirmed prior to treatment on
day 1.
- Women who are postmenopausal and wish to participate in the study, must also show
evidence of postmenopausal status. Postmenopausal status will be defined as: 1) A
woman who does not experience menstruation (known as amenorrhea) for 1 year or more
following the end of hormonal treatments. 2) Women who have reproductive/hormone
levels in the post-menopausal range for women under 50 as confirmed by medical
tests; 3) Radiation-induced oophorectomy (removal of one or more ovaries) with last
menses greater than 1 year ago; 4) Menopause caused by chemotherapy with greater
than 1 year since last menses 5) Surgical sterilization (bilateral oophorectomy or
hysterectomy).
- Male patients must use a condom during treatment and for 3 months after the last
dose of study drug (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.
- NOTE 1: Tests to confirm the eligibility of participants who have the above
mutations (altered germ or somatic cells) will take place at a germline or tumor
sequencing lab that is certified under the Clinical Laboratory Improvement
Amendments (CLIA). Eligibility of study participants will be confirmed once the
physical leading this study receives the official mutation report from the lab and
confirms that the participant's identified mutation fits the definition outlined
above. All other patients must consent to tumor and normal sample sequencing as
described in study procedures below during the prescreening phase to determine
eligibility.
- NOTE 2: Rare exceptions of participants who may have conflicting evidence regarding
protein function will be interpreted on an individual basis by the physician leading
the study.
Exclusion criteria:
Medical conditions:
- Any evidence of uncontrollable illness that the physician leading this study deems
undesirable for the patient to participate in the trial.
- Other malignancy (tumor/cancer) unless it has been treated with no evidence of
disease for 3 or more years except: adequately treated non-melanoma skin cancer,
curatively treated in situ cancer of the cervix, ductal carcinoma in situ (DCIS),
Stage 1, grade 1 endometrial carcinoma.
- Patients with BAP1 tumor predisposition syndrome will be included in the trial.
These patients may be eligible if they have a history of syndrome-related cancers,
provided they completed their surgery and chemotherapy more than three years prior
to registration, and the patient remains free of disease that continues to re-occur
or spread to other parts of the body.
- Patients with cancer that does not respond to platinum chemotherapy drugs (known as
platinum-resistant disease), defined as disease progression during or within 3
months of receiving chemotherapy.
- Resting electrocardiogram (ECG) that shows the patient has uncontrolled, potentially
reversible cardiac conditions or patients with congenital long QT syndrome (a heart
rhythm condition that can cause fast, chaotic heartbeats), as judged by the study's
lead physician.
- Persistent toxicities (greater than the Common Terminology Criteria for Adverse
Event (CTCAE) grade 2) caused by previous cancer therapy, excluding alopecia.
- Patients with myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML) or with
findings suggestive of MDS/AML.
- Patients with cancer cells that have moved from one part of their body to the brain
(brain metastases) causing the patient to show symptoms/signs of more serious
illness. A scan to confirm the absence of cancerous cells in the brain is not
required. The patient can receive a stable dose of corticosteroids before and during
the study as long as these were started at least 4 weeks prior to treatment.
- Patients with spinal cord compression unless considered to have received definitive
treatment for this and evidence of clinically stable disease for 28 days.
- Patients considered a poor medical risk due to a serious, uncontrolled medical
disorder, non-cancerous systemic disease or active, uncontrolled infection. Examples
include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within
3 months) myocardial infarction, uncontrolled major seizure disorder, unstable
spinal cord compression, superior vena cava syndrome, extensive interstitial
bilateral lung disease on High Resolution Computed Tomography (HRCT) scan or any
psychiatric disorder that prohibits obtaining informed consent.
- Patients unable to swallow oral medications and patients with gastrointestinal
disorders likely to interfere with absorption of the study medication.
- Patients who have a compromised immune system, e.g., patients who have tested
positive for human immunodeficiency virus (HIV).
- Patients with known active hepatitis (i.e. Hepatitis B or C) confirmed by medical
tests; patients with a past or resolved Hepatitis B infection are eligible. Patients
positive for hepatitis C virus are eligible only if samples of the patient's DNA
tests negative for hepatitis C, according to genetic tests (using polymerase chain
reaction).
Prior/concomitant therapy (medications/treatments that may conflict with the study drug,
olaparib):
- Any previous treatment with a type of drug/substance called a PARP inhibitor (which
stands for poly-ADP ribose polymerase inhibitor), including olaparib.
- Receipt of any systemic chemotherapy or radiotherapy (except for palliative reasons)
within 3 weeks prior to study treatment.
- Patients who are using strong cancer drugs called CYP3A inhibitors (also called
Cytochrome P-450) for treatment (eg. itraconazole, telithromycin, clarithromycin,
protease inhibitors boosted with ritonavir or cobicistat, indinavir, saquinavir,
nelfinavir, boceprevir, telaprevir) or moderate CYP3A inhibitors (eg. ciprofloxacin,
erythromycin, diltiazem, fluconazole, verapamil). Any treatment previously taken by
the patient must be washed out of the patient's system 2 weeks before taking
olaparib in this study.
- Patients who are using known strong CYP3A inducers (drugs for cancer patients
including phenobarbital, enzalutamide, phenytoin, rifampicin, rifabutin,
rifapentine, carbamazepine, nevirapine and St John's Wort) or moderate CYP3A
inducers (eg. bosentan, efavirenz, modafinil). Any patients taking enzalutamide must
have the drug washed out of their system 5 weeks before stating olaparib in this
study; patients taking phenobarbital and other agents must have the drug washed out
of their system 3 weeks before taking olaparib in this study.
