About this study

Official title: An Open-Label, Randomized, Multicenter Phase II Trial Comparing the Depletion of Malignant Stem Cells With Dasatinib vs. Imatinib in Patients With Newly Diagnosed Chronic Phase Chronic Myeloid

A randomized multi-center study comparing the effect of dasatinib and imatinib on malignant stem cells in newly diagnosed chronic phase chronic myeloid leukemia (CML) patients. The research hypothesis is that treatment with dasatinib 100 mg daily (QD) results in greater and more rapid depletion of the Philadelphia (Ph) -positive stem cell pool within 6 months of therapy than imatinib 400 mg QD in newly diagnosed CML patients. The study duration is 18 months and approximately 40 patients will be recruited to the study.

Read the detailed description

An Open-Label, Randomized, Multicenter Phase II Trial Comparing the depletion of malignant stem cells with Dasatinib vs. Imatinib in Patients with Newly Diagnosed Chronic Phase Chronic Myeloid Leukemia

Estimated Number of Study Centers and Countries/Regions: Appr. 12 sites in 5 Nordic countries. Stem cell analyses will be performed in 4 Nordic centers (Helsinki, Lund, Oslo and Stockholm).

Study Phase: II

Research Hypothesis: Treatment with dasatinib 100 mg daily (QD) results in greater and more rapid depletion of the Philadelphia (Ph) -positive stem cell pool within 6 months of therapy than imatinib 400 mg QD in newly diagnosed chronic phase (CP) chronic myeloid leukemia (CML) patients.

Primary Objective: To compare the number of Ph-positive cells in the stem cell compartment in newly diagnosed CP CML patients treated with dasatinib 100 mg QD vs. imatinib 400 mg QD.

Study Design: open-label randomized Phase II trial in newly diagnosed CML patients in CP. Patients will be randomized to receive dasatinib at a starting dose of 100 mg QD or imatinib at a starting dose of 400 mg QD.

Duration of Study: The study will be open for enrollment until the planned number of 40 patients is randomized. All patients will be treated and/or followed for up to 18 months. Based on the amendment 1 (Oct 2011), the follow-up of the patients will continue additional 4 years until 31.12.2015.

Number of Patients per Group: Approximately 40 patients will be randomized, 20 patients to dasatinib and 20 to imatinib. Additional patients will be recruited in case insufficient amount of representative samples have been obtained from first 40 patients.

Study Population: Patients 18 years or older with a newly diagnosed CP CML, not previously treated with any systemic treatments for CML

Study Assessments and Endpoints:

All stem cell assays are based on the preselection of CD34+ cells from large volume of bone marrow (BM) aspirates using paramagnetic beads. The CD34+ fraction will be further subdivided based on the expression of CD38 marker (positive vs. negative) using a sorting flow cytometer.

The primary endpoint is a comparison of proportion of Ph-positive cells in stem cell compartments (CD34+CD38neg and CD34+CD38+) at 6 months between the study arms.

Secondary endpoints are comparisons between treatment arms for: (1) the number of Ph-positive cells in all stem cell compartments at 1 and 3 months, (2) BCR-ABL RQ-PCR in blood at 1, 3, 6, 12 and 18 months, and (3) rate of CCyR within 3, 6, 12 and 18 months.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Imatinib and Dasatinib in people with Chronic Myeloid Leukemia, run by Norwegian University of Science and Technology at 7 sites in 3 countries.

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 17 inclusion and 19 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 25 Sep 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in Norway, Sweden, Finland. 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?

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?

Ph-positive cells in stem cell compartments (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00852566, which also lists 3 linked publications.

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 25 Sep 2017.
