What this trial studies

This observational study aims to assess the feasibility, safety, and clinical outcomes of discontinuing tyrosine kinase inhibitor (TKI) therapy in chronic phase chronic myeloid leukemia (CML) patients who have achieved deep treatment responses. Participants will undergo regular molecular monitoring of BCR-ABL transcript levels after stopping TKI therapy to ensure safety and detect any loss of major molecular response. The study focuses on adult patients in Taiwan who have maintained a deep treatment response for at least two years. The findings could provide valuable insights into the management of CML and the potential for treatment-free remission.

Who should consider this trial

Good fit: Ideal candidates are adults aged 20 and older with chronic phase CML who have achieved a deep treatment response and have been compliant with their treatment.

Not a fit: Patients who have documented resistance to second-generation TKIs or those who do not meet the eligibility criteria will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enable a significant number of CML patients to safely discontinue their medication without disease relapse.

How similar studies have performed: While there is limited data on Asian patients, similar studies in other populations have shown promising results regarding TKI discontinuation and treatment-free remission.
