Study information

Primary study designInterventional
Study designRandomised controlled trial
Secondary study designRandomised controlled trial
Scientific titleConventional therapy with chlorambucil versus fludarabine, used alone or in a novel combination with cyclophosphamide: a randomised controlled trial
Study acronymCLL 4
Study objectivesThis study will compare conventional therapy with chlorambucil versus the new agent fludarabine, used alone or in a novel combination with cyclophosphamide. End points of the trial will be:
1. Survival
2. Response to therapy
3. Duration of response
4. Toxicity
5. Quality of life
Ethics approval(s)South Thames MREC initially approved of this trial in 1998 (ref. no: MREC 98/1/101). An amendment to the protocol was accepted on 27th February 2001.
Health condition(s) or problem(s) studiedChronic lymphocytic leukaemia (CLL)
InterventionPatients will be randomised between chlorambucil versus fludarabine based treatment. Half of the patients randomised to fludarabine will be randomised between fludarabine plus cyclophosphamide and fludarabine alone.
