About this study
This is a non-randomized, prospective, single-group longitudinal study. The purpose of this study is to improve the decision making process used by physicians and patients when they are considering stopping their Tyrosine Kinase Inhibitor (TKI) medication.
Read the detailed description
This is a non-randomized, prospective, single-group longitudinal study. The overall objective is to improve decision making for TKI discontinuation in eligible chronic myelogenous leukemia (CML) patients. Patients with CML on treatment with imatinib, dasatinib, nilotinib, or bosutinib and are in confirmed deep molecular response will stop their TKI. Confirmed deep (> 4 log reduction) molecular response (>MR4) defined as p210 (bcr-abl) fusion protein (BCR-ABL) < 0.01%, for at least two years. The study will closely monitor patients using standard real-time Quantitative Polymerase Chain Reaction (RQ-PCR) testing for molecular recurrence, testing them monthly for six months, then every other month until 24 months, and then quarterly until 36 months. Concurrently, the study will assess a wide range of patient-reported outcomes (PROs) before stopping TKIs and after discontinuation in conjunction with Polymerase Chain Reaction (PCR) testing, though at fewer time points, utilizing online and/or phone questionnaires. Patients who have molecular CML recurrence based on RQ-PCR will restart imatinib, dasatinib, nilotinib, or bosutinib and will continue to be monitored for disease status and health status until the end of the study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Patients With Chronic Myeloid Leukemia (CML) Who Develop Molecular Recurrence After Discontinuing TKIs.
The number of patients who develop molecular recurrence after discontinuing TKIs. This will be reported as the number of new occurrences from the end of the prior time frame.
Measured: 1, 2, 3, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 27, 30, 33, 36 months
Patient-reported Health Status Related to Fatigue of Patients at Baseline (Before Stopping Tyrosine Kinase Inhibitors (TKIs)
Patient-reported health status of fatigue using the Patient-Reported Outcomes Measurement Information System (PROMIS) scales. The research team used five questions. The responses are in a Likert -style scale numbered one to five -- 1 (not at all) and 5 (very much). PROMIS scales use a T-score metric for interpretation of results. The mean score for a relevant reference population (United States general population in this case) is 50 and 10 is the standard deviation of that population. T-score range is 20 to 80. Thus, a score of 40 is one standard deviation lower than the reference population mean and a score of 60 is one standard deviation higher than the reference population mean. Higher scores for this scale are indicative of worse symptoms.
Measured: Baseline

Patient-reported Health Status Related to Fatigue of Patients at Baseline (Before Stopping Tyrosine Kinase Inhibitors (TKIs)
Time frame: Baseline
Patient-reported health status of fatigue using the Patient-Reported Outcomes Measurement Information System (PROMIS) scales. The research team used five questions. The responses are in a Likert -style scale numbered one to five -- 1 (not at all) and 5 (very much). PROMIS scales use a T-score metric for interpretation of results. The mean score for a relevant reference population (United States general population in this case) is 50 and 10 is the standard deviation of that population. T-score range is 20 to 80. Thus, a score of 40 is one standard deviation lower than the reference population mean and a score of 60 is one standard deviation higher than the reference population mean. Higher scores for this scale are indicative of worse symptoms.

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 10 inclusion and 6 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 3 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 16 sites 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 1 Mar 2023). 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 Patients With Chronic Myeloid Leukemia (CML) Who Develop Molecular Recurrence After Discontinuing TKIs. (time frame: 1, 2, 3, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 27, 30, 33, 36 months). The study lists 7 primary outcomes in all. 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 NCT02269267, which also lists 2 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?
