Combination of Dasatinib and Peg-Interferon Alpha 2b in First Line for Chronic Myeloid Leukemia in Chronic Phase
This trial is active, not recruiting.
|Condition||chronic phase of chronic myeloid leukemia|
|Treatments||dasatinib, peg-interferon alpha2b|
|Sponsor||Poitiers University Hospital|
|Start date||October 2013|
|End date||October 2018|
|Trial identifier||NCT01872442, DASA-PegIFN|
Interferon alpha was a therapy used in Chronic Myeloid Leukemia in Chronic phase prior to the advent of tyrosine kinase inhibitors. Synergistic effect of the combination of Peg-IFNα2a with Imatinib was demonstrated in the clinical SPIRIT trial. In this study, the investigators address the question of the efficacy and safety of dasatinib in combination with low dose of Peg-IFNα-2b as frontline therapy for patients with newly diagnosed Chronic Myeloid Leukemia in Chronic phase.
