Campath Maintenance in Chronic Lymphocytic Leukemia

Not Applicable

Terminated

• Conditions: Chronic Lymphocytic Leukemia
• Interventions: Drug: Campath

• Registration Number: NCT00587847
• Lead Sponsor: Northwell Health

Brief Summary

This is a study designed to test whether giving campath (also known as alemtuzumab) on a maintenance schedule will prolong the time until the patient requires chemotherapy.

Detailed Description

This is an open-label, single arm, proof-of-principle study of Campath (also known as 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.

Arm && Interventions

Group	Intervention	Description
Campath maintenance treatment	Campath	Single arm, open label trial of Campath on a maintenance schedule for patients who have had a response to prior conventional chemotherapy. Treatments consist of dose escalation (3, 10 and 30mg) during week 1 followed by weekly dosing of Campath at 30 mg once weekly for 7 weeks followed by Campath 30 mg every 2 weeks for 16 weeks followed by Campath 30 mg once every 3 weeks for 24 weeks. Total duration of treatment up to 48 weeks.

Primary Outcome Measures

Name	Time	Method
Time to Progression (Months)	Every 8 weeks	Time to progression calculated as the period, in months, between the date of the first dose of alemtuzumab and the first date of documented disease progression (NCI 1996 criteria) or death. Duration of response of all other participants who did not progress nor expire, had their event times calculated at the last date of follow-up.

Secondary Outcome Measures

Name	Time	Method
Rate of Infections	Weekly then every 2 weeks then every 3 weeks	Number of participants who developed clinical or laboratory evidence of infection.
