Failure of TKI treatment may either be primary (never achieved a response) or secondary resistance (loss of response).
- TKI treatment failure will be defined as 1 of the following:
- no CHR by 12 weeks (whether lost or never achieved)
- no partial cytogenetic response by 24 weeks (ie, 1 to 35% Ph-positive) (whether lost or never achieved) no major cytogenetic response by 52 weeks (ie, ≤35% Ph-positive) (whether lost or never achieved)
- progressive leukocytosis, defined as increasing white blood cell (WBC) count on at least 2 consecutive evaluations, at least 2 weeks apart and doubling from the nadir to ≥20000/μL or absolute increase in WBC by ≥50000/μL above the post-treatment nadir

About this study
Official title: An Open-Label, Single-Group Clinical Study to Evaluate the Pharmacokinetics, Safety,and Efficacy of Omacetaxine Mepesuccinate Given Subcutaneously as a Fixed Dose inPatients With Chronic Phase or Accelerated Phase Chronic Myeloid Leukemia Who Have Failed 2 or More Tyrosine Kinase Inhibitor Therapies
To satisfy a postmarketing requirement, the sponsor has been requested to conduct a Phase 1/Phase 2 single-group clinical study to investigate the pharmacokinetics and preliminary safety and efficacy of omacetaxine following a fixed-dose administration to patients with CP or AP CML who have failed 2 or more tyrosine kinase inhibitor (TKI) therapies.
Read the detailed description
Because the trial was not feasible due to the inability to accrue additional clinical study sites and enroll an adequate number of subjects, the FDA released the sponsor from the postmarketing requirement on 13 November 2017 and the study was stopped prematurely. Therefore, the study did not progress to the Phase 2 portion.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants Who Achieved a Major Response at Any Time During Treatment
The Independent Data Monitoring Committee assessments are summarized. Major response for participants with chronic phase CML was a major cytogenetic response (MCyR) defined as a complete cytogenetic response with no Ph+ metaphases, or a partial cytogenetic response with up to 35% Ph+ metaphases. Note that a complete hematologic response was not considered a major response.
Major response for participants with accelerated phase CML was a major hematologic response (MaHR) defined as a complete hematologic response or no evidence of leukemia, and/or a major cytogenic response (MCyR).
Measured: Day 1 up to Month 15 (longest treatment duration)
Secondary outcomes (12)
Longest Duration of Response At Study Termination
Duration of response was defined for responders as the time interval from the first reported date of a major cytogenetic response (MCyR) or a major hematologic response (MaHR) to the earliest date of objective evidence of disease progression (ie, development of accelerated-phase CML), relapse (ie, loss of complete hematologic or major cytogenetic response), or death. Kaplan-Meier estimates for duration of response were not performed due the small enrollment population and early termination of the study. What is reported is the longest duration of response observed prior to disease progression, death, lost to follow-up or study termination.
Measured: Day 1 to Day 541 (longest progression/survival follow-up)
Number of Participants Who Had a Molecular Response at Any Time During Treatment
Molecular response was defined by the decrease in the amount of BCR-ABL (an abnormality of chromosome 22) messenger ribonucleic acid (mRNA) measured by reverse transcriptase polymerase chain reaction (RT-PCR) or by the actual percentage of BCR-ABL mRNA transcripts (ratio of BCR-ABL transcript numbers to the number of control gene transcripts).
Measured: Day 1 up to Month 15
Number of Participants Who Were Alive and Progression-Free at Study Termination
Progression-free survival was defined as the time interval from the date of first dose to the date of the earliest objective evidence of disease progression (ie, development of accelerated-phase CML), relapse (ie, loss of complete hematologic or major cytogenetic response), or death. Kaplan-Meier estimates for time for progression-free survival were not performed due the small enrollment population and early termination of the study. What is reported is the number of participants who were alive and progression-free at the time of study termination.
Measured: Day 1 to Day 541 (longest progression/survival follow-up)
Number of Participants Who Were Alive at Study Termination
Overall survival was defined as the time interval from the date of the first dose to the date of death from any cause. Kaplan-Meier time estimates for overall survival were not performed due to the small enrollment population and early termination of the study. What is reported is the number of participants who were alive at the time of study termination.
Measured: Day 1 to Day 541 (longest progression/survival follow-up)

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
To satisfy a postmarketing requirement, the sponsor has been requested to conduct a Phase 1/Phase 2 single-group clinical study to investigate the pharmacokinetics and preliminary safety and efficacy of omacetaxine following a fixed-dose administration to patients with CP or AP CML who have failed 2 or more tyrosine kinase inhibitor (TKI) therapies.
Detailed description
Because the trial was not feasible due to the inability to accrue additional clinical study sites and enroll an adequate number of subjects, the FDA released the sponsor from the postmarketing requirement on 13 November 2017 and the study was stopped prematurely. Therefore, the study did not progress to the Phase 2 portion.

What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

What does the primary outcome measure?
Number of Participants Who Achieved a Major Response at Any Time During Treatment (time frame: Day 1 up to Month 15 (longest treatment duration)). It is what the study was designed to measure, not a finding.
