Olaparib and Temozolomide in Treating Patients With Advanced, Metastatic, or Unresectable Uterine Leiomyosarcoma
This phase II trial studies olaparib and temozolomide in treating patients with uterine leiomyosarcoma (LMS) that has spread to other places in the body (advanced or metastatic) or cannot be removed by surgery (unresectable). PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving olaparib and temozolomide may work better than giving either drug alone in treating patients with LMS.
Stanford is currently not accepting patients for this trial.

- Patients must have a life expectancy >= 16 weeks.
- Patients must be able to understand and be willing to sign a written informed consent
document. Patients with impaired decision-making capacity (IDMC) will be eligible if

- Patients must be willing and able to comply with the protocol for the duration of the
study, including undergoing treatment and attending scheduled visits and examinations.
- Patients with human immunodeficiency virus (HIV) infection may be enrolled on this
study provided: (a) they are on a stable regimen of highly active anti-retroviral
therapy (HAART) with no medications otherwise prohibited by this protocol (e.g.
drug-drug interactions) and (b) require no concurrent antibiotics or antifungals for
the prevention of opportunistic infections and (c) have a CD4 count above 250 cell/mcL
and an undetectable viral load on standard polymerase chain reaction (PCR)-based tests
within 1 month of initiation of study treatment. Other patients with clinically
significant immunosuppression, e.g. organ transplant patients, are not eligible. If
clarification is needed, this may be discussed with the medical monitor.
- Patients must be able to have temozolomide provided as a standard of care medication.
- Patients must not have had any previous treatment with any poly(adenosine
diphosphate[ADP]-ribose) polymerase (PARP) inhibitors, including olaparib, or prior

alopecia. Patients who have endocrinopathies associated with prior immunotherapy
treatment but which are controlled with replacement therapy are eligible.

bone marrow biopsy findings consistent with MDS and/or AML.
- Patients must not have active central nervous system (CNS) or leptomeningeal disease
at the time of enrollment. Patients with a history of such disease previously treated
with curative intent (such as with surgery or radiation) that have not progressed on
subsequent imaging, have been clinically asymptomatic, and have not received systemic
corticosteroids for at least 28 days, are eligible.
- Patients must not have a history of allergic reactions attributed to compounds of
similar chemical or biologic composition to olaparib or TMZ or any of the excipients

moderate CYP3A inhibitors (e.g., ciprofloxacin, erythromycin, diltiazem, fluconazole,
verapamil). The required washout period for strong or moderate CYP3A inhibitors prior
to starting olaparib is 2 weeks. Because the lists of these agents are constantly
changing, it is important to regularly consult a frequently-updated medical reference.
As part of the enrollment/informed consent procedures, the patient will be counseled
on the risk of interactions with other agents, and what to do if new medications need
to be prescribed or if the patient is considering a new over-the-counter medicine or

phenobarbital, enzalutamide, phenytoin, rifampicin, rifabutin, rifapentine,
carbamazepine, nevirapine and St John's wort) or moderate CYP3A inducers (e.g.,
bosentan, efavirenz, modafinil). The required washout period for strong or moderate
CYP3A inducers prior to starting olaparib is 5 weeks for enzalutamide or phenobarbital
and 3 weeks for other agents.
- Patients must not have an uncontrolled intercurrent illness including, but not limited
to, ongoing or active infection, 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 psychiatric illness
that would limit compliance with study requirements.
- Pregnant women are excluded from this study because olaparib is a PARP inhibitor with
the potential for teratogenic or abortifacient effects. 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. These potential risks may also apply to other agents used in this
- Patients must not have gastrointestinal disorders likely to interfere with absorption
of the study medication.
- Patients must not have had involvement in the planning and/or conduct of the study.
