Study information
Scientific title
Eradication of minimal residual disease (MRD) in chronic lymphocytic leukaemia (CLL) with alemtuzumab: a Phase II study
Acronym
UKCLL07
Study hypothesis
1. Is alemtuzumab effective and safe at treating patients with CLL whose disease is present at a low level following conventional treatments?
2. There will also be an investigation where MRD negative patients are monitored and retreated when necessary.

Condition
Chronic lymphocytic leukaemia (CLL)
Intervention
Patients who have previously achieved a minimal residual disease (MRD) negative remission and have relapsed at a molecular level, or who have a low level of MRD following conventional therapy will receive treatment for a minimum of 6 weeks (3 times per week) and a maximum of 12 weeks. Patients who have achieved an MRD negative state by conventional therapy may register for the study but will not be treated with alemtuzumab until CLL becomes detectable again.
Intervention type
Drug
Phase
Phase II
Drug names
Alemtuzumab
Primary outcome measure
1. Rate of achieving MRD negativity in patients with low levels of MRD following conventional therapy or who relapse at an MRD level after a previous MRD negative remission
2. Safety of alemtuzumab in the MRD positive setting
Secondary outcome measures
1. Clinical response to alemtuzumab therapy by National Cancer Institute (NCI) Criteria
2. Overall survival
3. Pharmacokinetic profile of alemtuzumab in the MRD setting
4. Safety and efficacy of repeated dosing as required to achieve sustained MRD negativity
Outcome of additional Monitoring Investigation (patients who are MRD negative at registration):
1. Time to MRD relapse
2. Effect of alemtuzumab used in a consolidation/maintenance approach on the expression of CD52 on CLL cells

Eligibility
Participant inclusion criteria
1. At least 18 years old
2. Written informed consent
3. Previous confirmation of B-cell CLL with a characteristic immunophenotype on peripheral blood flow cytometry
4. Creatinine and bilirubin <2 x upper limit of normal unless secondary to direct infiltration of the liver by CLL or haemolysis
5. Must have achieved a complete remission or good partial remission after therapy for CLL
6. At least six months since completing last therapy for CLL
7. Have detectable MRD, as shown by peripheral blood or bone marrow involvement or have attained an MRD negative remission. The latter group is eligible for registration and three-monthly monitoring for MRD relapse
