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

Completed · Phase 1

Conditions studied: Relapsed or Refractory Hematologic Malignancies

In brief

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 AML failing treatment with venetoclax-containing regimens. Treatment plan will consist of an induction phase, followed by a consolidation phase if applicable.

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 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
• 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.
• 2 Exclusion Criteria
• Subjects meeting any of the criteria below may not participate in the study:
• Patients with history of prior use of Omacetaxine.
• White blood cell count > 25 × 109/L (hydroxyurea permitted to decrease WBC count).
• History of other malignancies within 1 year prior to study entry, with the exception of: adequately treated in situ carcinoma of the cervix uteri or carcinoma in situ of breast; basal cell carcinoma of the skin or localized squamous cell carcinoma of the skin; previous malignancy confined and surgically resected (or treated with other modalities) with curative intent.
• Unresolved > grade 2 DIC.
• Investigational drug use within 4 weeks of study entry.
• History of CHF requiring treatment, left ventricular ejection fraction ≤ 40%, cardiac insufficiency grade III or IV per New York Heart Association classification (NYHA; see Appendix 2), or chronic stable angina
• Patients who are HIV positive.
• Known CNS involvement with AML.
• Previous hematopoietic stem cell transplant within 2 months.
• Patients who are positive for hepatitis B or C infection with the exception of those with an undetectable viral load over the prior 3 months. Subjects with serologic evidence of prior vaccination to HBV (i.e., HBs Ag-, and anti-HBs+) may participate.

• Patients with history of prior use of Omacetaxine.
• White blood cell count > 25 × 109/L (hydroxyurea permitted to decrease WBC count).
• History of other malignancies within 1 year prior to study entry, with the exception of: adequately treated in situ carcinoma of the cervix uteri or carcinoma in situ of breast; basal cell carcinoma of the skin or localized squamous cell carcinoma of the skin; previous malignancy confined and surgically resected (or treated with other modalities) with curative intent.

• Patients who are HIV positive.
• Known CNS involvement with AML.
• Previous hematopoietic stem cell transplant within 2 months.
• Patients who are positive for hepatitis B or C infection with the exception of those with an undetectable viral load over the prior 3 months. Subjects with serologic evidence of prior vaccination to HBV (i.e., HBs Ag-, and anti-HBs+) may participate.
• Active uncontrolled infection or severe systemic infection. Enrollment is possible after control of infection, at discretion of the treating physician.
• Pregnant or breastfeeding (NOTE: breast milk cannot be stored for future use while the mother is being treated on study).
• Patients who have received strong and/or moderate CYP3A inducers or inhibitors within 7 days prior to the initiation of study treatment unless therapy is deemed necessary by the treating physician. (See Section 8.7.2, Table 3 and Appendix 3).
• Patients who have consumed grapefruit, grapefruit products, Seville oranges (including marmalade containing Seville oranges) or Starfruit within 3 days prior to the initiation of study treatment.
• Malabsorption syndrome or other condition that precludes enteral route of administration.
• Psychological, familial, sociological, or geographical condition that would preclude study compliance and follow-up.
• Unable or unwilling to undergo a screening bone marrow study.
• Other severe acute or chronic medical or psychiatric condition, or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for enrollment in this study.
