The research project is trying to find out if we can improve the results of best available chemotherapy for Chronic Lymphocytic Leukaemia (CLL) by the addition of a new drug called lenalidomide.

Study type
Description of intervention(s) / exposure
After initial chemotherapy (the standard routine chemotherapy given to patients with CLL) patients will be randomised to either follow-up or to new medication Lenalidomide. Patients randomised to followup will visit their clinician regularly and have blood tests for the same amount of time as those randomised to Lenalidomide. Those randomised to Lenalidomide will commence at 5mg (2.5 mg for those with renal impairment) and, if tolerated, escalate to a maximum of 10mg (5mg in renally impaired) in 2.5mg increments every 2 cycles. At day 28 patient will undergo blood tests to ensure safe to continue with treatment. A new cycle will commence at the appropriate dose. This will occur for 24 months (2years).

Control group

Primary outcome [1] 257598 0
Time to clinical disease progression, or death, from the date of randomisation. Patients will be monitored for evidence of disease progresssion using clinical, radiological and flow cytometry according to standardised international criteria.
Timepoint [1] 257598 0
from randomisation until either disease progresses or death occurs.
Secondary outcome [1] 262865 0
Conversion to Minimal Residual Disease (MRD) negativity for randomized patients. Measured by flow cytometry of Bone Marrow sample.
Timepoint [1] 262865 0
from commencement of Lenalidomide. Lenalidomide treatment is for 2years.
Secondary outcome [2] 262866 0
Time to requirement for next therapy after Lenalidomide.
Timepoint [2] 262866 0
from when Lenalidomide is finished to time until next therapy is prescribed for the patient.
Secondary outcome [3] 262867 0
Percentage of patients with improvement in disease response. Results from routine tests such as bone marrow biospy and blood test will be used.
Timepoint [3] 262867 0
Patients will be monitored for evidence of disease progresssion using clinical, radiological and flow cytometry according to standardised international criteria.At regular timepoins during and after treatment. Timepoints may vary due to patient tolerance of Lenalidomide.
Secondary outcome [4] 262868 0
Overall survival, measured by clinician at follow up.
Timepoint [4] 262868 0
from time of registration to final followup. (for three years from time of last randomisation)
Secondary outcome [5] 262869 0
Tolerability of Lenalidomide consolidation.Measured by assessing patient ability to go on with next planned cycles - involves blood tests to ensure blood counts have recovered satisfactorily so as next cycle can be commenced.
Timepoint [5] 262869 0
monthly assessment of patient tolerability for the 2years of Lenalidomide maintenance therapy.
