Trial summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if giving cladribine once a day is more effective than giving cladribine once a week in patients with hairy cell leukemia. Read more about this study

About this study

Official title: Daily Versus Weekly Administration of 2-Chlorodeoxyadenosine (CDA) in Patients With Hairy Cell Leukemia

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if giving cladribine once a day is more effective than giving cladribine once a week in patients with hairy cell leukemia.

PURPOSE: Randomized phase III trial to compare the effectiveness of cladribine given once a day to cladribine given once a week in treating patients with hairy cell leukemia.

Read the detailed description

OBJECTIVES:

  • Compare the acute hematotoxicity and infection rate with daily and weekly administration of cladribine in patients with hairy cell leukemia.

OUTLINE: This is a randomized, multicenter study. Patients are randomized to one of two treatment arms.

  • Arm I: Patients receive daily subcutaneous bolus injections of cladribine (2-CDA) for 5 days (standard dose).
  • Arm II: Patients receive weekly subcutaneous bolus injections of 2-CDA for 5 weeks.

Patients showing complete or partial remission at evaluation on day 71 of the first treatment course do not receive any further treatment until relapse or disease progression is evident.

Patients showing minor or no response on day 71 of the first treatment course receive a subsequent course of standard dose 2-CDA.

Patients are followed every 3 months for 2 years, then every 6 months thereafter.

PROJECTED ACCRUAL: A total of 120 patients will be accrued for this study within 4 years.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing 2-chlorodeoxyadenosine (CDA) daily and 2-chlorodeoxyadenosine weekly 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Acute hematotoxicity at 10 weeks following study treatment (time frame: 10 weeks). 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 NCT00003746, 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.
