This phase II trial studies how well olaparib works in treating patients with glioma, cholangiocarcinoma, or solid tumors with IDH1 or IDH2 mutations that have spread to other places in the body (metastatic) and usually cannot be cured or controlled with treatment (refractory). Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

bosentan, efavirenz, modafinil); the required washout period prior to starting olaparib is 5 weeks for enzalutamide or phenobarbital and 3 weeks for other agents; because the lists of these agents are constantly changing, it is important to regularly consult a frequently updated drug information reference; medical reference texts such as the Physicians' Desk Reference may also provide this information; 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 herbal product - Persistent toxicities caused by previous cancer therapy; toxicities should have recovered to =< grade 1, excluding alopecia and stable chronic grade 2 toxicity that is not overlapping with presumed toxicities of olaparib - Patients with myelodysplastic syndrome/acute myeloid leukemia or with features suggestive of MDS/AML - Patients with symptomatic uncontrolled brain metastases; a scan to confirm the absence of brain metastases is not required; the patient can receive a stable dose of corticosteroids before and during the study if 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 with known uncontrolled brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events - Major surgery within 2 weeks of starting study treatment; effects from surgeries should have recovered to =< grade 1, with the exception of stable chronic grade 2 that is not overlapping with presumed toxicities of olaparib - 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 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 and would limit compliance with study requirements - Patients unable to swallow orally administered medication and patients with gastrointestinal disorders likely to interfere with absorption of the study medication - Women who are actively breast feeding - Immunocompromised patients, e.g., patients who are known to be serologically positive for human immunodeficiency virus (HIV); HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with Olaparib; in addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy; appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated - Patients with a known hypersensitivity to olaparib or any of the excipients of the product; history of allergic reactions attributed to compounds of similar chemica Inclusion Criteria: - Subjects must be able to understand the nature of this trial and provide written informed consent, prior to any study specific procedures; patients with Impaired Decision Making Capacity (IDMC) who have a close caregiver or legally authorized representative (LAR) may be considered eligible for this study at the treating physician's discretion, provided that the physician is reasonably sure that the possible risks and benefits of the study are clear and that the patient will take the drug as prescribed - Subjects must be diagnosed with a glioma, cholangiocarcinoma or other solid malignant tumor that has progressed despite standard therapy, or for which no effective standard therapy exists, with biopsy-confirmed evidence of an IDH1 or IDH2 mutation associated with neomorphic activity of the encoded proteins; patients must have IDH1 or IDH2 mutation which must be detected in a clinical accredited laboratory using a Food and Drug Administration (FDA)-approved molecular test or a validated deoxyribonucleic acid (DNA)-based assay conducted in a Clinical Laboratory Improvement Amendments (CLIA)-certified laboratory;

This phase II trial studies how well olaparib works in treating patients with acute myeloid leukemia that has come back (relapsed) or does not respond to treatment (refractory), or myelodysplastic syndrome. Patients must also have a change in the gene called the IDH gene (IDH mutation). Olaparib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. This study is being done to see if olaparib is better or worse in treating acute myeloid leukemia or myelodysplastic syndrome compared to the standard chemotherapy drugs.
