About this study

This Phase II hybrid decentralized multicenter study examines the outcomes of stopping Bruton tyrosine kinase inhibitor (BTKi) therapy in patients with chronic lymphocytic leukemia (CLL) who have remained in remission for at least two years. The primary objective is to determine how long patients remain free from disease progression or death after discontinuing treatment, measured as event free survival. The study also evaluates whether stopping BTKi therapy leads to improvements in quality of life and reductions in treatment related side effects. Researchers will follow patients over time to assess if the cancer returns, whether resistance to therapy develops, and how patients feel during the treatment free period. In addition, the trial will investigate how discontinuing BTKi therapy affects immune function, including whether immune recovery occurs and infection risk decreases. Preliminary data indicate that patients may experience a treatment free interval exceeding two years after stopping therapy, with associated improvements in quality of life. By prospectively evaluating a time limited treatment strategy, this trial aims to determine whether durable disease control can be maintained off therapy while also assessing the resolution of BTKi related adverse events and changes in patient reported outcomes. Overall, the study seeks to determine whether patients can safely discontinue BTKi therapy and potentially restart treatment later if needed, thereby maintaining disease control while reducing the burden of continuous therapy.
