Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Be ≥18 years old.
- Be diagnosed with relapsed or refractory leukemia including chronic myelogenous leukemia (CML), acute promyelocytic leukemia (APL), acute myelogenous leukemia (AML), or myelodysplastic syndrome (MDS)
- Relapsed defined as reappearance of leukemic blasts in the peripheral blood or the finding of ≥5% blasts in the bone marrow, not attributable to another cause (e.g., bone marrow regeneration after consolidation therapy).
- Refractory defined as no response to previous combined chemotherapy regimens including at least one cytarabine plus one anthracycline advanced solid tumors (i.e., breast, lung, head / neck, colorectal, melanoma, and sarcoma). Patients must have exhausted or become intolerant to all available therapies.
- (Patients with hematologic malignancies): Have completed all previous anti-leukemic therapy (except leukapheresis) at least 2 weeks prior to the first planned dose of OMA and must have fully recovered from side effects of a previous therapy unless, disease progression necessitates early therapy. Leukapheresis is allowed up to 24 hours prior to registration.
- (Patients with solid tumors): Patients may have measurable or unmeasurable disease. Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as ≥20 mm with conventional computerized tomography (CT) or magnetic resonance imaging (MRI) scans, or as ≥10 mm with spiral computerized tomography (CT) scan. Imaging must be performed within 28 days of the first dose of study drug.

- Have an estimated life expectancy of ≥12 weeks
- Have an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of ≤2 (see Appendix B)
- Be able to provide written informed consent prior to enrollment into the study. In the event that the patient is re-screened for study participation or a protocol amendment alters the care of an ongoing patient, a new informed consent form must be signed.
- Be male or a non-pregnant, non-lactating female. Fertile patients must agree to use an effective barrier method contraception (e.g., latex condom, diaphragm, or cervical cap) to avoid pregnancy while on therapy and for 6 months following the discontinuation of the study drug.

- Postmenopausal (amenorrheic for ≥12 months) Undergone a complete oophorectomy or hysterectomy.
- Have a negative serum pregnancy test within 7 days prior to the first dose of study drug (if patient is a female of childbearing potential).
- QTc <450 ms on screening 12-lead ECG (using Bazett's correction of QT interval formula [QTcB]).

- Be able and willing to comply with the requirements of the entire study.
Who cannot join
- Received previous treatment with OMA within 6 months of study entry.
- Have New York Heart Association (NYHA) Class 3 or 4 heart disease, active ischemia, or any uncontrolled, unstable cardiac condition for which treatment for the condition is indicated but is not controlled despite adequate therapy, including angina pectoris, cardiac arrhythmia, hypertension, or congestive heart failure (see Appendix D).
- Experienced a myocardial infarction in the previous 12 weeks.
- Have solid tumors with known bone marrow or central nervous system (CNS) involvement.
- Have an active, uncontrolled systemic infection considered opportunistic, life threatening, or clinically significant at the time of treatment.
- Are pregnant or lactating.
Show all 9Show fewer
- Received systemic chemotherapy in the 4 weeks prior to first dose of study drug, unless treatment is required for progressive leukemia. In patients with rapidly proliferating disease, hydroxyurea may be administered immediately prior to and during the first two cycles of treatment, if clinically indicated, to control disease.
- Received radiation therapy within 6 weeks of the first dose of study drug. Localized radiation for palliation may be administered with 2 weeks of the first dose of study drug.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Omacetaxine in people with Hematologic Tumors, run by ChemGenex Pharmaceuticals at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 16 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 May 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this 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.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pharmacokinetic Evaluation (time frame: 28 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 May 2014.
