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

Study population: Patients will be selected from patients referred to the primary hospital site for treatment and assessment. The patients will be approached by the physicians and or the study research nurse to consider participation in the study. Patients may be selected by participating off-site hospital centres and may be enrolled at those collaborating centres.

Who may be able to join

  • Diagnosis of CML in chronic phase.
  • ECOG <2.
  • Normal organ function and ULN Total bili, AST and ALT.
  • Must have the ability to understand and sign a written consent form

Who cannot join

  • Patients may not be receiving any other investigational agents.
  • May not have prior treatment with Imatinib, Dasatinib, Nilotinib or other tyrosine kinase inhibitors.
  • Patients must not have uncontrolled intercurrent illness including, but not limited to, ongoing or active infections, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmias, or psychiatric illness/social situations that would limit compliance with study requirements.
  • Pregnant or nursing mothers
  • Patients must have no prior malignancies except for; adequately treated non-melanoma skin cancer, cervical carcinoma-in-situ, adequately treated Stage I or II cancer from which the patient is in complete remission, or any other cancer from which the patient has been disease free for 5 years

About this study

Official title: A Study Investigating the Predictive Value of Philadelphia Positive Stem Cell Properties in Newly Diagnosed Patients With Chronic Myeloid in Chronic Phase Receiving Treatment With Imatinib

Imatinib (IM) is first-line treatment for patients with newly diagnosed CML in chronic phase. The drug is associated with high rates of cytogenetic responses with minimal toxicity in approximately 80% of patients. In 20% of patients however, the disease is either initially unresponsive to IM (Imatinib), resistance develops within a few months, or blast crisis occurs early and unexpectedly following an initial response. An increasing body of clinical evidence indicates that single agent molecularly targeted therapy (as in Gleevec/Imatinib) will not cure most patients with CML, as molecular remissions are rare. There is currently no clinically useful predictive tests to identify AT DIAGNOSIS those patients who are destined to be IM failures. The authors of this study have recently demonstrated that CML stem/progenitor cells are biologically insensitive to IM and are also genetically unstable and rapidly generate IM-resistant mutants in vitro and in vivo. The team recently discovered that the CD34 stem/progenitor cells of newly diagnosed CML patients who subsequently fail to respond to IM treatment show a reduced response to IM and a higher frequency of BCR-ABL mutations by comparison of 14 IM non-responders with 11 IM-responders. If this finding can be validated in a larger prospective cohort of patients, this predictive test could be used to more rationally design treatment plans with early addition of alternative therapies ie: Dasatinib or combination therapies for patients according to their individual risk profiles.

Hypothesis:

The clinical response of newly diagnosed chronic phase CML patients to IM can be predicted by certain biological properties of their CD34 stem/progenitor cells which are variable among patients.

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Myeloid Leukemia, run by University of British Columbia at 1 site in Canada.

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 5 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 30 Apr 2021. 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 Canada. 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.

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.

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 30 Apr 2021.
