Trial Information

Maintenance Alemtuzumab in Refractory Chronic Lymphocytic Leukemia

This is an open-label, single arm, proof-of-principle study of alemtuzumab maintenance
therapy administered subcutaneously at varying intervals for up to 1 year. Ongoing
prophylactic anti-infectives will be provided. Patients will be assessed for response every
2 months and for quality of life every 3 months while on treatment. Patients achieving a
presumptive complete response will receive no further treatment but will be followed for
response. Non-responding patients, with confirmed progressing disease following a minimum
of 8 doses will be discontinued from treatment and followed for survival. Responding
patients or patients with stable disease will undergo confirmatory assessment 2 months
following their end-of-treatment assessment. If remission has occurred, patients will be
followed off treatment until documented disease progression.

Inclusion Criteria:

clinical response of stable disease or better to previous treatment, and an Eastern
Cooperative Oncology Group performance status of 0-2
