About this study
Official title: Extension Study of a Study to Evaluate Efficacy and Safety of Imatinib (Glinib®) 600mg/Day Depending on Early Molecular Response in Newly Diagnosed Patients With Chronic Myeloid Leukemia in Chronic Phase
This study is an extension study (prospective observational study) of 'IDEAL' study (A Study to Evaluate Efficacy and Safety of Imatinib (Glinib) 600mg/day depending on Early Molecular Response in Newly Diagnosed Patients with Chronic Myeloid Leukemia in Chronic Phase, NCT02204722) to evaluate the duration of treatment response, disease progression, and survival status up to 5 years after the inclusion.
Read the detailed description
We have started a prospective study of evaluating efficacy and safety of imatinib 600mg/day depending on early molecular response in newly diagnosed patients with chronic myelogenous leukemia in chronic phase (IDEAL, NCT02204722), which will enroll 150 patients and follow up them for 1 years for the purpose of evaluating the primary endpoints - difference of major molecular response rate at 1 year. However, Chronic myelogenous is a disease which needs long-term for the outcome of treatment with BCR-ABL tyrosine kinase inhibitor. After the end of follow-up period of IDEAL study, subjects who agree with this extension study (IDEAL-E) will be enrolled and be followed up for additional 4 years to evaluate the duration of treatment response, disease progression, and survival status. Subjects who will be enrolled in this prospective observational study will be treated with drugs - imatinib 300-600mg / nilotinib 600mg / dasatinib 100mg - which has been chosen by the each investigator according to the drug compliance and overall response. The drug choice will be at the discretion of each investigator, and the overall adverse event / molecular response will be monitored every 6 months in this prospective observational study.
- Being tested
- IDEAL-E observation (investigators choice of imatinib, nilotinib, dasatinib, radotinib)

After the end of follow-up period of IDEAL study, subjects who agree with this extension study (IDEAL-E) will be enrolled and be followed up for additional 4 years to evaluate the duration of treatment response, disease progression, and survival status. Subjects who will be enrolled in this prospective observational study will be treated with drugs - imatinib 300-600mg / nilotinib 600mg / dasatinib 100mg / radotinib 800mg - which has been chosen by the each investigator according to the drug compliance and overall response. The drug choice will be at the discretion of each investigator, and the overall adverse event / molecular response will be monitored every 6 months in this prospective observational study.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study is an extension study (prospective observational study) of 'IDEAL' study (A Study to Evaluate Efficacy and Safety of Imatinib (Glinib) 600mg/day depending on Early Molecular Response in Newly Diagnosed Patients with Chronic Myeloid Leukemia in Chronic Phase, NCT02204722) to evaluate the duration of treatment response, disease progression, and survival status up to 5 years after the inclusion.
Detailed description
We have started a prospective study of evaluating efficacy and safety of imatinib 600mg/day depending on early molecular response in newly diagnosed patients with chronic myelogenous leukemia in chronic phase (IDEAL, NCT02204722), which will enroll 150 patients and follow up them for 1 years for the purpose of evaluating the primary endpoints - difference of major molecular response rate at 1 year. However, Chronic myelogenous is a disease which needs long-term for the outcome of treatment with BCR-ABL tyrosine kinase inhibitor. After the end of follow-up period of IDEAL study, subjects who agree with this extension study (IDEAL-E) will be enrolled and be followed up for additional 4 years to evaluate the duration of treatment response, disease progression, and survival status. Subjects who will be enrolled in this prospective observational study will be treated with drugs - imatinib 300-600mg / nilotinib 600mg / dasatinib 100mg - which has been chosen by the each investigator according to the drug compliance and overall response. The drug choice will be at the discretion of each investigator, and the overall adverse event / molecular response will be monitored every 6 months in this prospective observational study.

Questions about this trial
What is this clinical trial studying?
An observational study of Leukemia, Myelogenous, Chronic, BCR-ABL Positive, run by Asan Medical Center at 12 sites in South Korea.
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 2 inclusion and 1 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: withdrawn, as of the sponsor's last update on 8 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 12 sites in South Korea. 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 was withdrawn before enrolling participants, so there are no results.
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?
progression-free survival rate (time frame: 5-year). 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 NCT02421926, which also lists 10 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 8 Jul 2019.
