Clinical Trial Summary

This phase Ib/II trials studies the side effects of decitabine/cedazuridine (ASTX727) and venetoclax in combination with ivosidenib or enasidenib, and how well they work in treating patients with acute myeloid leukemia that has come back (relapsed) or does not respond to treatment (refractory). ASTX727 is the combination of a fixed dose of 2 drugs, cedazuridine and decitabine. Cedazuridine may slow down how fast decitabine is broken down by the body, and decitabine may block abnormal cells or cancer cells from growing. Venetoclax may stop the growth of cancer cells by blocking BCL-2, a protein needed for cancer cell survival. Enasidenib and ivosidenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving decitabine/cedazuridine and venetoclax in combination with ivosidenib or enasidenib may help control acute myeloid leukemia.


Description:

PRIMARY OBJECTIVE: I. To determine the safety and tolerability and recommended phase 2 dose (RP2D) of oral decitabine/cedazuridine (ASTX727) and venetoclax in combination with either ivosidenib (Arm A) or enasidenib (Arm B) for patients with acute myeloid leukemia. (Phase Ib) II. To determine the overall response rate (complete response [CR], complete remission with incomplete hematologic recovery [CRh], morphologic leukemia-free state [MLFS] and partial response [PR)] of oral decitabine/cedazuridine (ASTX727) and venetoclax in combination with either ivosidenib (Arm A) or enasidenib (Arm B) for patients with acute myeloid leukemia. (Phase 2) SECONDARY OBJECTIVES: I. To determine duration of response (DOR), event-free survival (EFS), and overall survival (OS). II. To evaluate occurrence of minimal residual disease (MRD) negative status by multiparameter flow cytometry and molecular evaluation. EXPLORATORY OBJECTIVE: I. To investigate global gene expression profiles, deoxyribonucleic acid (DNA) methylation profiles, BH3 profiling and other potential prognostic markers to explore predictors of antitumor activity and/or resistance to treatment. OUTLINE: Patients are assigned to 1 of 2 arms. ARM A: Patients receive decitabine/cedazuridine orally (PO) daily on days 1-5, venetoclax PO daily on days 1-14, and ivosidenib PO daily on days 1-28. Treatment repeats every 28 days for 12 cycles in the absence of disease progression or unacceptable toxicity. ARM B: Patients receive decitabine/cedazuridine PO daily on days 1-5, venetoclax PO daily on days 1-14, and enasidenib PO daily on days 1-28. Treatment repeats every 28 days for 12 cycles in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months.

Oral hydroxyurea and/or cytarabine (up to 2 g/m^2) for patients with rapidly proliferative disease is allowed before the start of study therapy, as needed, for clinical benefit and after discussion with the principle investigator (PI). Concurrent therapy for central nervous system (CNS) prophylaxis or continuation of therapy for controlled CNS disease is permitted - Male subjects who are sexually active with a women of childbearing potential (WOCBP) and who have not had vasectomies must be willing to use a barrier method of contraception and refrain from sperm donation from initial study drug until 90 days after last dose of study drug - Willing and able to provide informed consent Exclusion Criteria: - Patients with t(15;17) karyotypic abnormality or acute promyelocytic leukemia (French-American-British [FAB] class M3-AML) - Patients with any concurrent uncontrolled clinically significant medical condition including life-threatening severe infection, or psychiatric illness, which could place the patient at unacceptable risk of study treatment - Patients with active graft-versus-host-disease (GVHD) status post stem cell transplant (patients without active GVHD on chronic suppressive immunosuppression and/or phototherapy for chronic skin GVHD are permitted after discussion with the PI) - Patients with any severe gastrointestinal or metabolic condition which could interfere with the absorption of oral study medications - Corrected QT (QTc) interval using Fridericia's formula (QTcF) >= 450 msec. Bundle branch block and prolonged QTc interval are permitted after discussion with the PI - Known active hepatitis B (HBV) or hepatitis C (HCV) infection or known human immunodeficiency virus (HIV) infection - Subject has a white blood cell count > 25 x 10^9/L. (Note: Hydroxyurea is permitted to meet this criterion) - Nursing women, women of childbearing potential (WOCBP) with positive urine pregnancy test, or women of childbearing potential who are not willing to maintain adequate contraception - Appropriate highly effective method(s) of contraception include oral or injectable hormonal birth control, intrauterine device (IUD), and double barrier methods (for example a condom in combination with a spermicide)

Outcome

Type Measure Description Time frame Safety issue
Primary Dose limiting toxicity (Phase Ib) Will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 5 by organ system. Up to 1 cycle (1 cycle = 28 days)
Primary Overall response rate (ORR) (Phase II) Defined as complete remission (CR), CR with incomplete hematologic recovery, CR with incomplete count recovery, partial response or marrow clearance of blasts. Will estimate the ORR for the combination treatmen1t, along with the Bayesian 95% credible interval. Within 4 months of treatment
Primary Incidence of adverse events (Phase II) Assessed using Common Toxicity Criteria version 5.0. Safety data will be summarized using frequency and percentage, by category and severity. Within 4 months of treatment
Secondary Event-free survival (EFS) The Kaplan-Meier method will be used to estimate the probabilities of EFS. Log-rank tests will be used to compare among subgroups of patients in terms of EFS. Time interval between treatment start until disease progression, relapse/refractory, or death due to any cause, assessed up to 3 years
Secondary Overall survival (OS) The Kaplan-Meier method will be used to estimate the probabilities of OS. Log-rank tests will be used to compare among subgroups of patients in terms of OS. Time interval between treatment start until death due to any cause, assessed up to 3 years
Secondary Duration of response The Kaplan-Meier method will be used to estimate the probabilities and log-rank tests will be used to compare among subgroups of patients. Up to 3 years
Secondary Minimal residual disease negative status Will be summarized graphically and with descriptive statistics. The association between molecular and cellular markers and overall response and/or resistance will be assessed through logistic regression analyses. Paired t-test or Wilcoxon signed rank test will be used to assess the marker change over time. Up to 3 years
