About this study
Official title: A Phase II Study of Fludarabine + Rituximab Induction Followed by Alemtuzumab (Campath-1H, NSC #715969, IND #10864) Administered Subcutaneously as Consolidation in Untreated Patients With B-Cell Chronic Lymphocytic Leukemia
This phase II trial is studying how well giving fludarabine together with rituximab followed by alemtuzumab works in treating patients with chronic lymphocytic leukemia. Monoclonal antibodies, such as rituximab and alemtuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others can find cancer cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy, such as fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving fludarabine together with rituximab followed by alemtuzumab may kill more cancer cells.
Read the detailed description
PRIMARY OBJECTIVES:
- To determine the rate of complete response and toxicity of concurrent treatment with fludarabine and rituximab followed by consolidative alemtuzumab in patients with previously untreated, but symptomatic, CLL.
II. To determine if alemtuzumab improves the CR rate with acceptable toxicity when administered as consolidation therapy following induction therapy with fludarabine and rituximab.
III. To estimate the progression-free and overall survival of high risk (VH gene unmutated and those with p53 dysfunction) and low-risk (others) patients following therapy with fludarabine and rituximab induction and consolidative alemtuzumab.
IV. To determine the frequency of molecular (PCR) remission following fludarabine and rituximab induction therapy and alemtuzumab consolidation therapy and if this serves as a surrogate marker for prolonged progression-free and overall survival.
SECONDARY OBJECTIVES:
- To determine the effect of concurrent treatment with fludarabine and rituximab followed by consolidative alemtuzumab on recovery of T-cells, NK cells, and serum immunoglobulin levels.
II. To determine clinical and molecular features that predict for poor response to fludarabine and rituximab induction and subsequent alemtuzumab consolidation therapy.
III. To assess preliminarily the molecular features of CLL at relapse in patients responding to chemoimmunotherapy for CLL.
IV. To determine the frequency of patients who remain at high risk for progression of CLL despite this therapy and who are thus eligible for nonmyeloablative stem cell transplantation studies such as CALGB 109901.
- To perform limited rituximab pharmacokinetics to determine the ideal schedule of administration for a subsequent rituximab maintenance treatment approach following induction therapy with fludarabine and rituximab.
OUTLINE:
Patients receive induction therapy comprising rituximab IV over 4 hours on days 1, 3, and 5 of course 1 and day 1 of all subsequent courses and fludarabine IV over 30 minutes on days 1-5. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression.
Approximately 4 months after completion of induction therapy, patients achieving a partial response, nodular partial response, or stable disease receive consolidation therapy comprising alemtuzumab subcutaneously on days 1-3. Treatment repeats weekly for up to 6 courses in the absence of disease progression.
Patients are followed at 2 months, every 3 months for 1 year, and then every 6 months for 7 years from study entry.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing alemtuzumab, rituximab and fludarabine phosphate in people with B-cell Chronic Lymphocytic Leukemia and Stage I Chronic Lymphocytic Leukemia, run by National Cancer Institute (NCI) at 2 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?
The sponsor lists 19 inclusion and 0 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 21 May 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 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?
Yes. Results are posted in the registry (first posted 3 Dec 2012). 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?
Number of Participants With a Complete Response After Treatment With Fludarabine & Rituximab Followed by Alemtuzumab (time frame: Duration of treatment (up to 13.5 months)). 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 NCT00098670, 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 21 May 2014.
