Study title

DASTOP-2 = A multicenter trial where patients with CML stop medication a second time

Scientific title

Persistence of major molecular remission in chronic myeloid leukemia after a second stop of TKI treatment in patients who failed an initial stop attempt: A prospective multicenter study (ClinicalTrials.gov NCT03573596; EudraCT 2016-004106-34, )

Type of study

Treatment discontinuation trials

Current status

No longer recruiting

What is the purpose of the study

The purpose of this study is to assess treatment-free remission (persistence of major molecular remission) after a second attempt to stop TKI treatment

Key inclusion criteria

This study includes male or female patients who:

– are at least 18 years old
– have chronic myeloid leukemia (CML) in chronic phase (CP) with confirmed presence of the BCR/ABL1 gene
– who have had a molecular relapse after attempting to stop therapy with a tyrosine kinase inhibitor (TKI) within the EUROSKI study or outside the study but according to EUROSKI procedures. Patients who attempted stopping outside the study must have received a TKI for at least 3 years before the first stop, including dasatinib in this study during the last 2 years. Patients must have been in deep molecular response (MR4) for at least 1 year before stopping.
– who have been treated with any TKI for at least 1 year after having failed a first attempt to stop treatment with a TKI
