Olaparib in Treating Patients with Advanced Glioma, Cholangiocarcinoma, or Solid Tumors with IDH1 or IDH2 Mutations

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.

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; only specific mutations that lead to a neomorphic phenotype will be eligible for enrollment, and include IDH1: R132V, R132G, R132S, R132L, R132C and R132H; IDH2: R140W, R140L, R140Q, R172W, R172G, R172S, R172M, R172K

Patients must have tumors determined to be easily accessible for biopsy and must be willing to have serial biopsies (with a third biopsy upon evidence of disease progression); in case of multiple lesions, tumor biopsies will be performed on the most accessible site of disease; all possible precautions to avoid complications will be taken, including discussions in multidisciplinary meetings, if needed; patients affected by glioma will not be considered for study biopsies

Patients must be willing to undergo extra blood sampling for correlative studies

Subjects with extracranial disease must have evaluable disease by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1); subjects affected by glioma must have evaluable disease by Response Assessment in Neuro-Oncology Criteria (RANO) criteria

For subjects with glioma, specific inclusion criteria are as follows: * The disease should be recurrent or transformed glioma; subjects must not have had prior surgery (biopsy allowed) or radiation therapy within 3 weeks of enrollment * There must be an enhancing component of disease, as evaluated on pre-treatment magnetic resonance imaging (MRI) * For patients with World Health Organization (WHO) grade III or IV glioma and progressive disease 70% tumor cell nuclei in areas), high or progressive increase in MIB-1 proliferation index compared with prior biopsy, or evidence for histologic progression or increased anaplasia in tumor); ** Note: Given the difficulty of differentiating true progression from pseudoprogression, clinical decline alone, in the absence of radiographic or histologic confirmation of progression, will not be sufficient for definition of progressive disease in the first 12 weeks after completion of concurrent chemoradiotherapy * For patients with WHO grade III or IV glioma and progressive disease >= 12 weeks after completion of chemoradiotherapy, progression can be defined by the following set of criteria: ** New contrast-enhancing lesion outside of radiation field on decreasing, stable, or increasing doses of corticosteroids ** Increase by >= 25% in the sum of the products of perpendicular diameters between the first post-radiotherapy scan, or a subsequent scan with smaller tumor size, and the scan at 12 weeks or later on stable or increasing doses of corticosteroids ** For patients receiving antiangiogenic therapy, significant increase in T2/fluid attenuated inversion recovery (FLAIR) non-enhancing lesion may also be considered progressive disease; the increased T2/FLAIR must have occurred with the patient on stable or increasing doses of corticosteroids compared with baseline scan or best response after initiation of therapy and not be a result of comorbid events (e.g., effects of radiation therapy, demyelination, ischemic injury, infection, seizures, postoperative changes, or other treatment effects) ** Note: Clinical deterioration alone is not attributable to concurrent medication or comorbid conditions is sufficient to declare progression on current treatment but not for entry onto a clinical trial for recurrence * For patients with WHO grade II glioma progression is defined by any one of the following: ** Development of new lesions or increase of enhancement (radiological evidence of malignant transformation) ** A 25% increase of the T2 or FLAIR non-enhancing lesion on stable or increasing doses of corticosteroids compared with baseline scan or best response after initiation of therapy, not attributable to radiation effect or to comorbid events

For subject with extracranial disease, they must have at least one lesion, not previously irradiated, that can be accurately measured at baseline as >= 10 mm in the longest diameter (except lymph nodes which must have short axis >= 15 mm) with computed tomography (CT) or magnetic resonance imaging (MRI) or >= 10 mm with calipers by clinical exam OR at least one lesion (measurable and/or non-measurable) that can be accurately assessed by CT/MRI/pain x-ray/clinical exam at baseline and follow up visits

Subjects must have progressive cancer at the time of study entry; prior experimental (non-FDA approved) therapies (other than drugs that share the same target) and immunotherapies are allowed; patients must not have received these therapies for 30 days or five half-lives of the drug (whichever is less) prior to the initiation of study treatment; toxicities from these therapies should have recovered to =

Concomitant use of known strong CYP3A inhibitors (e.g. itraconazole, telithromycin, clarithromycin, protease inhibitors boosted with ritonavir or cobicistat, indinavir, saquinavir, nelfinavir, boceprevir, telaprevir) or moderate CYP3A inhibitors (e.g. ciprofloxacin, erythromycin, diltiazem, fluconazole, verapamil); the required washout period 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 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

Concomitant use of known strong (e.g. 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 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 =
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 =
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

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 chemical or biologic composition to olaparib

Whole blood transfusions in the last 120 days prior to entry to the study (packed red blood cells and platelet transfusions are acceptable)

Patients who are receiving any other investigational agents

Pregnant women are excluded from this study because olaparib is an agent 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

Patients with myelodysplastic syndrome (MDS) or acute myelogenous leukemia (AML), or features suggestive of MDS/AML
