Pevonedistat and Low Dose Cytarabine for the Treatment of Relapsed or Refractory Acute Myeloid Leukemia or Myelodysplastic Syndrome

Trial Status: Active

This phase I trial studies the side effects and best dose of pevonedistat when given together with low dose cytarabine for the treatment of acute myeloid leukemia or myelodysplastic syndrome that has come back (relapsed) or does not respond the treatment (refractory). Pevonedistat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Cytarabine is an anticancer drug and may disrupt the creation of deoxyribonucleic acid (DNA) which stops cancer cells from dividing and increasing in number. Giving pevonedistat together with low dose cytarabine may work better in slowing down the growth or destroying cancer cells compared to low dose cytarabine alone.

Inclusion Criteria

  • Relapsed/refractory acute myelogenous leukemia (AML) where no alternative life prolonging therapy exists. Treatment naive patients may also be considered eligible if in the opinion of the investigator, these patients are unlikely to benefit from alternative therapy (e.g. conventional chemotherapy, hypomethylating agents)
  • Relapsed/refractory myelodysplastic syndrome (MDS) following at least two courses of a hypomethylating agent (e.g. azacitidine or decitabine). Patients intolerant of hypomethylating agents (irrespective of the number of cycles administered) will also be considered eligible. MDS eligibility limited to patients with intermediate, high or very high risk based on Revised International Prognostic Scoring System (IPSS-R) (Note: Intermediate risk patients must have >= 5% bone marrow myeloblasts)
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2
  • Albumin > 2.7 g/dL
  • Total bilirubin =< upper limit of normal (ULN) except in patients with Gilbert’s syndrome. Patients with Gilbert’s syndrome may enroll if direct bilirubin =< 1.5 x ULN of the direct bilirubin
  • Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) must be =< 2.5 x ULN
  • Creatinine =< 1.5 x ULN or calculated creatinine clearance > 50 ml/min
  • Hemoglobin > 8 g/dL (prior red blood cell [RBC] transfusion allowed). Patients may be transfused to achieve this value. Elevated indirect bilirubin due to post-transfusion hemolysis is allowed
  • White blood cell (WBC) count < 50,000/uL before administration of PEVONEDISTAT on cycle 1 day 1. Note: Hydroxyurea may be used to control the level of circulating leukemic blast cell counts to not lower than 10,000/uL during the study

PRIMARY OBJECTIVE:

I. To determine the safety profile and establish the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of PEVONEDISTAT administered intravenously when combined with low dose cytarabine (LDAC) given subcutaneously in patients with acute myelogenous leukemia (AML) and advanced myelodysplastic syndromes (MDS).

SECONDARY OBJECTIVES:

I. To evaluate preliminary efficacy of the PEVONEDISTAT when combined with LDAC.

II. To describe the pharmacokinetics (PK) of intravenous (IV)-administered PEVONEDISTAT in plasma when combined with LDAC.

III. To investigate the pharmacodynamic (PD) effects of PEVONEDISTAT when combined with LDAC.

EXPLORATORY OBJECTIVES:

I. To assess baseline serum and leukemic blast specimens for candidate biomarkers of response to treatment with LDAC/PEVONEDISTAT including, but not limited to, CDT1 and NRF2 expression levels as determined by immunoblotting (relative optical density) or by enzyme-linked immunosorbent assay (ELISA) (ng/mL).

II. To assess bone marrow blasts for evidence of DNA damage response after treatment with LDAC/pevonedistat. III. To assess the potential relationships between cytogenetic abnormalities in AML or MDS and response to PEVONEDISTAT/LDAC combination therapy.

OUTLINE: This is a dose-escalation study of pevonedistat.

Patients receive low dose cytarabine subcutaneously (SC) on days 1-10 or days 1-5 and 8-12 and pevonedistat intravenously (IV) over 60 minutes on days 1, 3, and 5. Treatment repeats every 28 days for up to 16 cycles in the absence of disease progression or unacceptable toxicity. Patients receiving clinical benefit may continue to receive low dose cytarabine and pevonedistat beyond 16 cycles.

After completion of study treatment, patients are followed up at 30 days.
