A Phase II Open-Label Study of the Subcutaneous Administration of Homoharringtonine (Omacetaxine Mepesuccinate) in the Treatment of Patients With Chronic Myeloid Leukemia (CML) Who Have Failed or Are Intolerant to Tyrosine Kinase Inhibitor Therapy

A Phase II open-label trial of subcutaneous HHT (omacetaxine mepesuccinate) in the treatment of patients who are resistant to or intolerant to Tyrosine Kinase Inhibitors.

NCT00462943 Chronic Myeloid Leukemia
MeSH: Leukemia Leukemia, Myeloid Leukemia, Myelogenous, Chronic, BCR-ABL Positive
HPO: Chronic myelogenous leukemia Leukemia Myeloid leukemia

1 Interventions

Name: Omacetaxine mepesuccinate

Description: Induction: 1.25mg/m^2 subcutaneously twice daily for 14 consecutive days, every 28 days. Maintenance: 1.25mg/m^2 subcutaneously twice daily for 7 consecutive days, every 28 days. Response targets during induction vary by chronic myeloid leukemia (CML) subclass (chronic, accelerated, or blast phase). Participants will complete at least one cycle (14 days treatment of a 28 day cycle) of induction therapy before changing to maintenance therapy. Participants not demonstrating evidence of clinical response after 6 induction cycles will be considered for removal from the study.

Type: Drug

OMA


Primary Outcomes

Description: Subpopulations reflect chronic myeloid leukemia (CML) phases at the time of enrollment: chronic, accelerated, and blast phase. Primary endpoints as adjudicated by the Data Monitoring Committee were used for the primary analyses. Overall hematologic response for chronic phase participants includes confirmed complete hematologic response (CHR). Overall hematologic response for accelerated or blast phase participants includes confirmed complete hematologic response (CHR), no evidence of leukemia (NEL), or return to chronic phase (RCP). Hematologic response must last >= 8 weeks to be considered meaningful. Response rates by disease phase were examined relative to an a priori value of 2.5% using a one-sided lower 95% exact binomial confidence limit. If the lower limit from the one-sided lower 95% confidence limit exceeds 2.5%, the observed response rate will have exceeded the minimum threshold required to demonstrate efficacy.

Measure: Percentage of Participants Achieving an Overall Hematologic Response by Subpopulation and Total Population

Time: Day 1 up to 6 months

Description: Subpopulations reflect chronic myeloid leukemia (CML) phases at the time of enrollment: chronic, accelerated, and blast phase. Primary endpoints as adjudicated by the Data Monitoring Committee were used for the primary analyses. Major cytogenetic response includes complete or partial response. Both confirmed and unconfirmed major cytogenetic response is considered meaningful. Unconfirmed response is based on a single bone marrow cytogenetic evaluation for participants where a confirmatory evaluation is not available. Complete response shows 0% Philadelphia chromosome positive (Ph+) cells. A partial response shows >0% - 35% Ph+ cells. Response rates by disease phase were examined relative to an a priori value of 2.5% using a one-sided lower 95% exact binomial confidence limit. If the lower limit from the one-sided lower 95% confidence limit exceeds 2.5%, the observed response rate will have exceeded the minimum threshold required to demonstrate efficacy.

Measure: Percentage of Participants Achieving a Major Cytogenetic Response by Subpopulation and Total Population

Time: Day 1 up to 9 months

Description: TEAE are any untoward events that were newly occurring or worsening from Baseline. Treatment related toxicity was considered by the investigator to be unrelated, possibly, probably or unknown related to study drug. Severity was graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v3.0 on the following scale: Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = life-threatening, Grade 5 = death. A serious adverse event (SAE) is any untoward medical occurrence that is fatal or life-threatening; results in persistent or significant disability or incapacity; requires or prolongs in-patient hospitalization; is a congenital anomaly/birth defect in the offspring of a patient; and conditions not included in the above that may jeopardize the patient or may require intervention to prevent one of the outcomes listed above. A participant is only counted once in each category (at worst severity or strongest relationship).

Measure: Number of Participants With Treatment-Emergent Adverse Events (TEAEs) by Subpopulation and Total

Time: up to 4 years

Secondary Outcomes

Description: Cytogenetic response categories: Complete: 0% Ph+ cells Partial: >0%-35% Ph+ cells Minor: >35%-65% Ph+ cells Minimal: >65%-95% Ph+ cells No Response: >95% Ph+ cells Unevaluable: <20 metaphases were examined and/or response could not be assigned

Description: MMR is defined as a ratio of BCR-ABL/standard gene of less than 0.1% according to the international scale. BCR-ABL is a fusion gene of the breakpoint cluster region [BCR] gene and Abelson proto-oncogene [ABL] genes). This analysis used the standard gene GUS. Analysis was performed by quantitative reverse transcription polymerase chain reaction (qRT-PCR) of peripheral blood.

Measure: Percentage of Participants With Major Molecular Response (MMR) Representing the Degree of Suppression of BCR-ABL Transcript Levels Using the Housekeeping Gene GUS

Time: Day 1 up to Month 6

Description: MMR is defined as a ratio of BCR-ABL/standard gene of less than 0.1% according to the international scale. BCR-ABL is a fusion gene of the breakpoint cluster region [BCR] gene and Abelson proto-oncogene [ABL] genes). This analysis used the standard gene ABL. Analysis was performed by quantitative reverse transcription polymerase chain reaction (qRT-PCR) of peripheral blood.
