Brief Summary:
This single arm study evaluated the bone marrow response, safety, and tolerability of 6 months treatment with Avastin (bevacizumab) monotherapy in patients with chronic lymphocytic leukemia. Patients received 8 cycles (21 days duration) of Avastin monotherapy (15mg/kg) with 6 months of follow-up.

Condition or disease Intervention/treatment Phase
Lymphocytic Leukemia, Chronic Drug: Bevacizumab Phase 2

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 2 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: ML21206 - Bevacizumab in Chronic Lymphocytic Leukemia: A Proof of Concept Study
Study Start Date : September 2008
Primary Completion Date : March 2009
Study Completion Date : March 2009

Arm Intervention/treatment
Experimental: Bevacizumab 15 mg/kg
Participants received bevacizumab 15 mg/kg intravenously on Day 1 of each 3-week cycle for 8 cycles.
Drug: Bevacizumab
Bevacizumab was supplied as a sterile liquid in single-use vials.
Other Name: Avastin

Primary Outcome Measures :
  1. Bone Marrow Response [ Time Frame: Baseline to the end of treatment (up to 24 weeks) ]
    Bone marrow response was defined as the change in percentage of infiltration at the interim staging (after 4 cycles of treatment) and the end of treatment.

Secondary Outcome Measures :
  1. Best Overall Response (BOR) [ Time Frame: Baseline to the end of treatment (up to 24 weeks) ]
    The percentage of participants in each BOR category (complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD)) is reported. CR was defined as the disappearance of all target (TL) and non-target lesions (non-TL). PR was defined as ≥ 30% decrease in the sum of the longest diameter (SLD) of TLs, taking as reference the baseline SLD, or the persistence of 1 or more non-TLs. For TLs, SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest SLD since treatment started. For non-TLs, SD was defined as the persistence of 1 or more lesions. PD was defined as ≥ 20% increase in the sum of the longest diameter of TLs, taking as reference the smallest SLD recorded since treatment started, the unequivocal progression of existing non-TLs, or the appearance of 1 or more new lesions.
