Acute Myeloid Leukemia Clinical Trial

Safety and Efficacy of Venetoclax With Escalating Doses of Omacetaxine in Patients With Acute Myeloid Leukemia

Summary

This will be a single arm, open label Phase Ib dose-escalation study of the combination of VEN and OM, conducted using an innovative Bayesian Optimal Interval-design, to find the MTD in participants with relapsed/refractory hematologic malignancies including those failing treatment with venetoclax-containing regimens. Treatment plan will consist of an induction phase, followed by a consolidation phase if applicable.

Full Description

This is a Phase Ib study of VEN and OM, the investigator will conduct a Bayesian Optimal Interval-designed trial following the approach of Yuan et al 40 to find the MTD with a target DLT rate of 2%, 4 pre-specified doses, and between 24 and up to 30 participants. Beginning with the first participant treated at the lowest dose of OM 0.625 mg/m2 q12h with VEN 400 mg, dose escalation and de-escalation of OM will involve a comparison of the observed DLT rate (p) at the current dose with a pair of fixed, pre-specified boundary rates: λe (escalation) with p ≤ 0.157; λd (de-escalation) with p ≥ 0.238; or otherwise remain at the same dose per the dosing schedule. The trial will start with a cohort size of 1 participant (unless DLT is experienced) and escalated for each subsequent participant until the first DLT occurs and the current dose cohort is expanded to 3.40 In a simulation of these conditions with a target DLT rate of 20% (1), the percentage correct selection of the MTD is between 60% with enrollment of 20 participants and 70% with enrollment of 24 participants. Implementation of the trial design will be performed using R package 'BOIN'. If the investigator observes an unexpected toxicity in Cohort 1 the investigator will use OM 0.5 mg/m2 daily with VEN for Cohort -1 Following each cycle, participants will be evaluated for complete response (CR) by International Working Group (IWG) criteria 41

Eligibility Criteria

Inclusion Criteria:

Age 18-75 years of age at time of consent.
Have relapsed/refractory AML (primary or secondary) and have progressed on ≥ 1 line of therapy, at least one of which must have included a VEN-containing regimen.
Eastern Cooperative Oncology Group (ECOG) Performance score 0-2 (see Appendix 1).

Prior cancer treatment must be completed at least 21 days prior to registration and the subject must have recovered from all reversible acute toxic effects of the regimen (other than alopecia) to ≤ Grade 1 or baseline.

i. With the exception of Hydroxyurea; if Hydroxyurea is used to reduce the white blood blast count to < 25 x 109/L, then it must be discontinued at least 48 hours prior to registration and bone marrow/peripheral blood sampling, and the subject must have recovered from all reversible acute toxic effects to ≤ Grade 1 or baseline.

Life expectancy of 6 months or greater as determined by the treating physician.

Demonstrate adequate organ function as defined in the table below; all screening labs to be obtained within 28 days prior to registration.

System Laboratory Value Renal Creatinine/Calculated creatinine clearance (CrCl) CrCl ≥ 50 mL/min using the Cockcroft-Gault formula Hepatic Bilirubin ≤ 1.5 × upper limit of normal (ULN). Excluding patients diagnosed with Gilbert's syndrome Aspartate aminotransferase (AST) ≤ 3 × ULN Alanine aminotransferase (ALT) ≤ 3 × ULN

Provided written informed consent and HIPAA authorization for release of personal health information, approved by an Institutional Review Board (IRB).
NOTE: HIPAA authorization may be included in the informed consent or obtained separately.
Females of childbearing potential must have a negative serum pregnancy test within 7 days prior to registration. NOTE: Females are considered of child bearing potential unless they are surgically sterile (have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or they have not experienced menstruation for at least 12 consecutive months
Females of childbearing potential and males must be willing to use effective contraception during treatment and for at least 30 days after the last dose of Venetoclax. Females will be advised to use effective contraception for at least 6 months after the last dose of omacetaxine and males for at least 3 months after the last dose of omacetaxine.
As determined by the enrolling physician or protocol designee, ability of the subject to understand and comply with study procedures for the entire length of the study.
