About this study
Official title: The Effect of Interleukin 11 on Thrombocytopenia Associated With Imatinib or Other Tyrosine Kinase Inhibitor Therapy in Patients With Chronic Myelogenous Leukemia
The goal of this clinical research study is to find out if IL-11 (NeumegaTM) may increase the platelet count in patients with Chronic myeloid leukemia (CML) who develop low platelet counts while receiving therapy with imatinib mesylate (Gleevec, STI571), or other tyrosine kinase inhibitors such as AMN107, dasatinib, or SK1606.
Primary Objective:

- To determine efficacy of low-dose interleukin-11, (IL-11, oprelvekin, NeumegaTM) in improving the thrombocytopenia associate with imatinib or other tyrosine kinase inhibitor therapy in patients with CML.
Secondary Objective:
- To determine the safety of low-dose IL-11 in patients with CML and thrombocytopenia associated with imatinib or other tyrosine kinase inhibitors
Read the detailed description
IL-11 is a hormone normally produced in your body that plays a role in stimulating the production of platelets.
Before you can start treatment on this study, you will have what are called "screening tests". These tests will help the doctor decide if you are eligible to take part in the study. You will have a blood sample (1 teaspoon) collected to check your platelet count. Women who are able to have children must have a negative blood pregnancy test.
If you are found to be eligible to take part in this study, you will receive one injection of IL-11 under the skin (usually of the arms, legs or abdomen) 3 times a week. If your platelet count increases, treatment will continue on this schedule as long as a platelet increase is observed. If the treatment is well tolerated but there is not enough of a platelet improvement, the dose and frequency of IL-11 injections may be increased. If the platelet count becomes high enough, treatment may be stopped but may also be restarted if necessary.
During therapy with IL-11, additional blood samples (1 teaspoon each) will be collected to measure the platelet count every week until the platelets are stable and then every 2 to 6 weeks while you are receiving treatment on study. No other tests are required for this study.
While you are on this study, you will continue your treatment with imatinib mesylate or other tyrosine kinase inhibitor as decided by your doctor for standard care.You will be taken off if there is no response to treatment or if there are unacceptable side effects. There will be no follow-up after you go off study.
This is an investigational study. The Food and Drug Administration (FDA) has approved IL-11 for use in chemotherapy-caused low platelet counts. A maximum of 30 patients will take part in this study. All will be enrolled at M. D. Anderson.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Interleukin-11 (IL-11 or Neumega) in people with Leukemia and Chronic Myelogenous Leukemia, run by M.D. Anderson Cancer Center 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 4 inclusion and 8 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 20 Feb 2012. 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 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.
Are results available for this study?
Yes. Results are posted in the registry (first posted 4 May 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Number of Participants With Complete Response (time frame: Weekly platelet count till stabilized with on-going review while receiving treatment (study total 2 years)). 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 20 Feb 2012.
