Fludarabine and Monoclonal Antibody Therapy in Treating Patients With Untreated B-cell Chronic Lymphocytic Leukemia
A Phase 2 study testing rituximab and fludarabine phosphate in people with Leukemia, run by Alliance for Clinical Trials in Oncology at 34 sites in United States.
Trial summary
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Read more about this study

About this study
Official title: A Randomized Phase II Study of Concurrent Fludarabine + Chimeric Anti-CD20 Monoclonal Antibody IDEC-C2B8 (Rituximab) [NSC# 687451] Induction Followed By Rituximab Consolidation In Untreated Patients With B-Cell Chronic Lymphocytic Leukemia
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Combining monoclonal antibody therapy with chemotherapy may kill more cancer cells.
PURPOSE: Randomized phase II trial to compare the effectiveness of fludarabine given with or without monoclonal antibody therapy followed by monoclonal antibody therapy alone in treating patients who have untreated B-cell chronic lymphocytic leukemia.
Read the detailed description
OBJECTIVES: I. Determine the response rate and toxicity profile of concurrent and consolidative chimeric anti-CD20 monoclonal antibody IDEC-C2B8 (rituximab) therapy compared to consolidative rituximab therapy in patients with chronic lymphocytic leukemia treated with fludarabine. II. Assess the complete response (CR) rate in patients receiving concurrent therapy with rituximab and fludarabine. III. Assess the frequency of conversion of a partial response (PR) to a CR or stable disease to either PR or CR in patients receiving consolidative therapy with rituximab. IV. Follow the effects of rituximab and fludarabine on the immunologic markers CD4, CD8, IgG, IgA, and IgM. V. Assess the progression-free and overall survival of these patients.
OUTLINE: This is a randomized study. Patients are stratified according to stage (I and II vs III and IV). Patients are assigned to 1 of 2 treatment arms. Arm I consists of fludarabine and chimeric anti-CD20 monoclonal antibody IDEC-C2B8 (rituximab) induction, and arm II consists of fludarabine induction. Arm I: Rituximab is administered IV over 4 hours on day 1, on day 3, and over 1 hour on day 5 of week 1. Subsequent doses are given over 1 hour on day 1 every 4 weeks for a total of 6 courses. Fludarabine IV is administered over 10-30 minutes daily for 5 days during weeks 1, 5, 9, 13, 17, and 21 for a total of 6 courses. Following the sixth course of fludarabine, patients undergo clinical staging and are then observed for an additional 2 months, after which they undergo repeat clinical staging, including bone marrow aspiration. Patients achieving a complete or partial response or stable disease then proceed to consolidation therapy consisting of weekly intravenous infusions of rituximab once weekly for 4 weeks. Arm II (Fludarabine Induction): Patients receive fludarabine IV over 10-30 minutes daily for 5 days during weeks 1, 5, 9, 13, 17, and 21 for a total of 6 courses. Patients then proceed as in arm I. Patients are followed every 3 months for 1 year, and then every 6 months thereafter.
PROJECTED ACCRUAL: A maximum of 100 patients will be accrued for this study within 12 months.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing rituximab and fludarabine phosphate in people with Leukemia, run by Alliance for Clinical Trials in Oncology at 34 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Jul 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 34 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
progression-free survival (time frame: Up to 5 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00003248, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jul 2016.
