MSIT = Malaysia Stop Tyrosine Kinase Inhibitor Trial [Malaysia]

Study title

MSIT = Malaysia Stop Tyrosine Kinase Inhibitor Trial [Malaysia]

Scientific title

A Randomized Control Trial Comparing Peginterferon-α-2a Versus Observation After Stopping Tyrosine Kinase Inhibitor in Chronic Myeloid Leukemia With Deep Molecular Response for at Least Two Years ( NCT02381379)

Type of study

Treatment discontinuation trial
in a single country

Current status

Active, not recruiting

What is the purpose of the study

This study compares two groups of CML patients in chronic phase with deep molecular response for at least 2 years. After stopping tyrosine kinase inhibitors, one group will use peginterferon-α-2a starting at 180µg weekly for one year whereas the other group will not use any active medication that might affect CML.
The study will compare the two groups with regard to relapse rate, time to re-attain deep molecular response after restarting TKIs in patients who relapse and time to regain deep molecular response after relapse after restarting whatever treatment.

Key inclusion criteria

To be considered for inclusion in this study patients must be 18 years or older and have been diagnosed with chronic phase (CP) chronic myeloid leukemai (CML). They have been treated with ongoing tyrosine kinase inhibitors (TKI) at any dose for at least 3 years.
Patients have achieved stable deep molecular response (MR4.5) on International Scale (IS) for at least 2 years. The last deep MR result must have been from within 3 months of enrollment.
