About this study
Official title: Rituximab (IDEC-C2B8, Mabthera) in Patients With Hairy Cell Leukemia Relapsing After Treatment With 2-Chlorodeoxyadenosine (CDA)
RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells.
PURPOSE: Phase II trial to study the effectiveness of monoclonal antibody therapy consisting of rituximab in treating patients with refractory or recurrent hairy cell leukemia following cladribine therapy.
Read the detailed description
OBJECTIVES:
- Determine the rate of complete and partial remission, remission duration, and relapse free survival after treatment with rituximab in patients with refractory or recurrent hairy cell leukemia who previously received cladribine.
- Determine the acute and long term toxicity of rituximab in these patients.
OUTLINE: This is an open-label, multicenter study.
Patients receive rituximab IV over several hours once a week for 4 weeks.
Patients are followed every 3 months for 3 years and every 6 months thereafter.
PROJECTED ACCRUAL: A total of 8-25 patients will be accrued for this study within 3 years.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing rituximab in people with Leukemia, run by Swiss Cancer Institute at 1 site in Switzerland.
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 15 May 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Switzerland. 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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00003757, which also lists 1 linked publication.
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 15 May 2012.
