Evaluation of remission status will take place 4 months after treatment. In addition, it will be tested whether patients with non-optimal response will have a benefit from a second cycle of cladribine. Non-optimal response is: patients with detectable residual disease; achievement of partial remission or detectable residual infiltration in the bone marrow.
