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.
The PRIME Trial: PARP Inhibition in IDH Mutant Effectiveness Trial. A Phase II Study of Olaparib in Isocitrate Dehydrogenase (IDH) Mutant Relapsed/Refractory Acute Myeloid Leukemia and Myelodysplastic Syndrome
- To determine the rate of complete response (CR) to olaparib using a composite CR endpoint (CR + CR with incomplete hematologic response [CRi] + CR with partial hematologic response [CRh]) in subjects with isocitrate dehydrogenase (IDH)1/2 mutant myelodysplastic syndrome (MDS) or IDH1/2-mutant acute myeloid leukemia (AML).
- To determine the overall response rate (ORR) to olaparib using a composite ORR endpoint (CR + morphologic leukemia-free state [MLFS] + partial response [PR]) in patients with IDH mutant AML or MDS treated with olaparib.
II. To establish the progression free survival (PFS) of patients with IDH mutant AML or MDS treated with olaparib.
III. To determine the overall survival (OS) of patients with IDH mutant AML or MDS treated with olaparib.
IV. To establish the duration of response (DOR) to treatment with olaparib. V. To evaluate the safety and tolerability of olaparib in AML or MDS patients.
- To establish a relationship between treatment response and correlative studies such as plasma and bone marrow 2-hydroxyglutarate (2HG) levels, and IDH variant allele frequency.
II. To evaluate persistence of double strand breaks in IDH 1/2 mutant AML or MDS.
III. To evaluate response to therapy in the different IDH mutant genotypes.
IV. To perform molecular profiling assays on malignant and normal tissues, including, but not limited to, whole exome sequencing (WES), ribonucleic acid (RNA) sequencing (RNAseq) order to:
IVa. Identify potential predictive and prognostic biomarkers beyond any genomic alteration by which treatment may be assigned.
IVb. Identify resistance mechanisms using genomic deoxyribonucleic acid (DNA)- and RNA-based assessment platforms.
- To contribute genetic analysis data from de-identified biospecimens to Genomic Data Commons (GDC), a well annotated cancer molecular and clinical data repository, for current and future research; specimens will be annotated with key clinical data, including presentation, diagnosis, staging, summary treatment, and if possible, outcome.
VI. To bank blood and bone marrow aspirate obtained from patients at the Experimental Therapeutics Clinical Trials Network (ETCTN) Biorepository at Nationwide Children's Hospital.
Patients receive olaparib orally (PO) twice daily (BID) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity for up to 12 cycles. Patients also undergo bone marrow aspiration and collection of blood throughout the study.
After completion of study treatment, patients are followed up at 90 days and then every 3 months until death.

Open to people ages 18 years and up
- Age >= 18 years. Because no dosing or adverse event (AE) data are currently available on the use of olaparib in patients < 18 years of age, children are excluded from this study, but will be eligible for future pediatric trials

- Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial.
- For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated.
- Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load.

Patients with hematologic malignancies are expected to have hematologic abnormalities at study entry. Hematologic abnormalities that are thought to be primarily related to leukemia are not considered to be toxicities (AEs) and do not need to resolve to < grade 1.
- Eastern Cooperative Oncology Group (ECOG) performance status 0-2 (Karnofsky >= 60%).
- Patient must have recovered from toxicities of any prior treatment regimen (no Common Terminology Criteria for Adverse Events [CTCAE] grading over 1 for non-hematological toxicities, return to baseline for hematological values).

- Patients who are pregnant or nursing. 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 AEs 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 study.
