  • Phenotypically characterized CD20 + CLL defined as: 1) the predominant population of cells share B-cell antigens with CD5 in the absence of other pan-T-celI markers (CD3, CD2, etc.); 2) B-cell expresses either kappa or lambda light chains; and 3) surface immunoglobulin (slg) with low-cell surface density expression.

About this study

Official title: Phase II Clinical Protocol for the Treatment of Patients With Previously Untreated Chronic Lymphocytic Leukemia

This research study will look at the effects (good or bad) of administering cyclophosphamide, fludarabine, and rituximab. Clinical studies with combination therapy have shown higher response rates than using single drugs, and this study will evaluate the side effects and effectiveness of this combination.

Read the detailed description

This study is designed to expand on the highly successful combination of rituximab, fludarabine and cyclophosphamide for patients with previously untreated CLL. Responses in the range of 90-98% with 55% complete responses are reported. However, bone marrow toxicity has been a significant problem. This trial is designed to reduce the bone marrow toxicity by decreasing the doses of fludarabine and cyclophosphamide, but doubling the dose of rituximab with a maintenance dose of rituximab for up to two years, to maintain or even enhance efficacy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • FludarabineDrug

    Fludarabine is usually administered by IV infusion over 30 minutes or longer.

  • CyclophosphamideDrug

    The dosage is a solution of 20 mg/mI. IV infusion over 1 hour.

  • RituximabDrug

    First Infusion: The rituximab solution for infusion should be administered intravenously at an initial rate of 50 mg/hr. Subsequent rituximab infusions can be administered at an initial rate of 100 mg/hr, and increased by 100 mg/hr increments at 30-minute intervals, to a maximum of 400 mg/hr as tolerated.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Tolerability of Rituximab, Cyclophosphamide and Fludarabine in Patients With Previously Untreated CLL/SLL

    The number of patients who experience any grade 3-5 toxicity.

    Measured: Duration of treatment on study

  2. Efficacy of Rituximab, Cyclophosphamide and Fludarabine in Patients With Previously Untreated CLL/SLL

    The number of patients who experience a complete clinical response.

    Measured: Three months after the sixth cycle (9 months)

Secondary outcomes (2)
  1. Overall Survival Rate

    The percentage of participants who are still alive.

    Measured: Five years after starting rituximab, cyclophosphamide and fludarabine

  2. Duration of Response

    The length of time for which the complete response is maintained.

    Measured: From complete response to the time of progressive disease, death or last clinical examination

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Fludarabine, Cyclophosphamide and Rituximab in people with Chronic Lymphocytic Leukemia, run by University of Pittsburgh at 1 site 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?

The sponsor lists 23 inclusion and 10 exclusion criteria. 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 4 Feb 2016. 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 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?

Yes. Results are posted in the registry (first posted 4 Feb 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Tolerability of Rituximab, Cyclophosphamide and Fludarabine in Patients With Previously Untreated CLL/SLL (time frame: Duration of treatment on study). 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?
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 4 Feb 2016.
