Brief Summary

This phase I trial studies the best dose and side effects of M3814 when given in combination with mitoxantrone, etoposide, and cytarabine in treating patients with acute myeloid leukemia that has come back (relapsed) or does not respond to treatment (refractory). M3814 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as mitoxantrone and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill cancer cells. Giving M3814 in combination with mitoxantrone, etoposide, and cytarabine may lower the chance of the acute myeloid leukemia growing or spreading.

Detailed Description

PRIMARY OBJECTIVE:

I. To assess the safety and tolerability and determine the recommended phase two dose (RP2D) of peposertib (M3814) in combination with mitoxantrone, etoposide, and cytarabine (MEC) in patients with relapsed or refractory (R/R) acute myeloid leukemia (AML).

SECONDARY OBJECTIVES:

I. To characterize the pharmacokinetic (PK) profile of MEC alone and of M3814 in combination with MEC.

II. To evaluate the preliminary efficacy of M3814 in combination with MEC in patients with R/R AML as measured by the response rate (complete remission [CR] plus CR with incomplete count recovery [CRi]), duration of CR/CRi (DOR), event-free survival (EFS) and overall survival (OS).

EXPLORATORY OBJECTIVES:

I. To evaluate correlative biomarkers of M3814 target engagement and response. II. To correlate cytogenetic and molecular abnormalities with response. III. To evaluate the rates of early mortality and allogeneic hematopoietic cell transplantation.

IV. To perform molecular profiling assays on malignant and normal tissues, including, but not limited to, whole exome sequencing (WES) and messenger ribonucleic acid (RNA) sequencing (RNAseq), in 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.

V. 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.

OUTLINE: This is a dose-escalation study of peposertib followed by a dose-expansion study.

Patients receive peposertib orally (PO) twice daily (BID) on days 2-21, mitoxantrone intravenously (IV) over 15 minutes, etoposide IV over 60 minutes and cytarabine IV over 60 minutes on days 1-5 in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo echocardiogram (ECHO) or multigated acquisition scan (MUGA) during baseline, and blood collection and bone marrow biopsy throughout the study.

After completion of study treatment, patients are followed up at 30 days, every 3 months for 1 year, then every 6 months thereafter up to 5 years.

• Refractory: no CR or CRi after one or more cycles of induction. Induction cycles include regimens with the intent to achieve remission and can include high intensity and/or low intensity regimens
• Age >= 18 years. Because no dosing or adverse event data are currently available on the use of M3814 in combination with mitoxantrone, etoposide, and cytarabine in patients < 18 years of age, children are excluded from this study, but will be eligible for future pediatric trials

If there is evidence of chronic hepatitis B virus (HBV) infection, HBV viral load must be undetectable on suppressive therapy, if indicated. If there is history of hepatitis C virus (HCV) infection, the patient must have been treated and have undetectable HCV viral load
• Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial

Exclusion Criteria

• Patients must not have had prior treatment with MEC
• Patients must not have documented active central nervous system (CNS) involvement by leukemia. Patients with known 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 (AEs)
• Patients must not have received any other investigational or commercial agents or therapies administered with the intention to treat their leukemia within 14 days or 5 elimination half-lives (whichever is shorter) of first receipt of study drug, with the exception of hydroxyurea and/or leukapheresis used to control white blood cell counts
• Patients who cannot discontinue concomitant medications or herbal supplements that are strong inhibitors or strong inducers of cytochrome P450 (CYP) isoenzymes CYP3A4/5, CYP2C9 and CYP2C19 during treatment with M3814. Concomitant use of CYP1A2, CYP2B6 and CYP3A4/5 substrates with a narrow therapeutic index are also excluded during treatment with M3814. Patients may confer with the study doctor to determine if alternative medications can be used. The following categories of medications and herbal supplements must be discontinued for at least the specified period of time prior to the first dose of M3814:

• Strong inducers of CYP3A4/5, CYP2C9 and CYP2C19: >= 3 weeks or 5 elimination half-lives (whichever is shorter) prior to the first dose of M3814
• Strong inhibitors of CYP3A4/5, CYP2C9 and CYP2C19: >= 1 week or 5 elimination half-lives (whichever is shorter) prior to the first dose of M3814
• Substrates of CYP1A2, CYP2B6 and CYP3A4/5 with a narrow therapeutic index: >= 1 day prior to the first dose of M3814
• Concomitant use of histamine-2 (H2)-blockers or proton pump inhibitors should be avoided as these might affect absorption of M3814; administrations have to be discontinued at least 5 days or 5 elimination half-lives (whichever is shorter) prior to the first dose of M3814. Antacid drugs should not be taken 1 hour before and until 2 hours after M3814 administration
• Patients receiving sorivudine or any chemically related analogues (such as brivudine) are excluded
• Patients who require oral or parenteral anticoagulants or thrombolytic agents for therapeutic purposes (including coumadin and warfarin), or who received such agents within 5 days or 5 elimination half-lives (whichever is shorter) of the first dose of M3814. Low and high-molecular weight heparins are permitted provided the platelets are maintained at greater than 30,000/mm^3
• Patients with ongoing active infection or who have received a live attenuated vaccine within 30 days of dosing with M3814

• Unstable angina;
• Congestive heart failure (New York Heart Association [NYHA] class III or IV);
• Myocardial infarction (MI) within 6 months prior to first dose. Patients who had ischemic heart disease such as acute coronary syndrome (ACS), MI, and/or revascularization more than 6 months before screening and who are without cardiac symptoms or those with a prior non-ST elevation MI (NSTEM) due to demand-supply mismatch (NSTEM Type II) may enroll
• Patients should not have severe and/or uncontrolled medical conditions or other conditions that, in the opinion of the investigator, could affect their participation in the study
• Patients with psychiatric illness/social situations that would limit compliance with study requirements
• Patients should not be pregnant or breastfeeding

• A history of additional risk factors for TdP (e.g., heart failure, hypokalemia, family history of Long QT syndrome)
• The use of concomitant medications that prolong the QT/QTc interval
• Gastrointestinal disorders that may affect the M3814 absorption
• Patients will need to avoid any intake of grapefruit, grapefruit juice, Seville oranges, Seville orange marmalade, or other products containing grapefruit or Seville oranges within 7 days before the first administration of M3814 and throughout the duration of M3814 treatment
