Autoimmune disease related to CLL, e.g. idiopathic thrombocytopenic purpura (ITP) or autoimmune hemolytic anemia, is permitted if treatment with steroids has not been required in the two months prior to registration. Hypothyroidism without evidence of Grave's Disease or Hashimoto's thyroiditis is permitted.
  • Major organ system dysfunction including (but not limited to): New York Heart Association Class III or IV (Appendix B, page 51), pulmonary disease requiring the use of inhaled steroids or bronchodilators, renal, hepatic, gastrointestinal, neurologic, or psychiatric dysfunction which would impair patient's ability to participate in the trial

About this study

Official title: A Phase I/II Study of Xcellerated T Cells(tm) in Patients With Chronic Lymphocytic Leukemia (CLL)

Patients will have immune cells collected and then expanded outside of the body. Patients will receive an infusion of a large number of expanded immune cells. There will be three dose levels studied. The goal of the study will be to determine the safety as well as potential efficacy of this treatment.

Read the detailed description

This is a Phase I/II single arm dose escalation study of a novel T cell immunotherapy for chronic lymphocytic leukemia (CLL). Patients will receive one dose of Xcellerated T Cells(tm), an ex vivo activated and expanded autologous T cell product, in an attempt to enhance immune responses with anti-tumor activity. This study is being conducted to test the safety and determine the maximum tolerated dose (MTD) of Xcellerated T Cells in patients with CLL. In addition, lymphocyte counts, lymph node area, and quantitative immunoglobulins will be assessed for preliminary evidence of a therapeutic effect. In correlative studies, changes in the phenotype of T and B lymphocytes will be evaluated by flow cytometry. Changes in T cell repertoire and anti-tumor immune activity will also be assessed. It is expected that 12 to 18 patients will be treated.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Infusion of Activated & Expanded Autologous T Cells in people with Chronic Lymphocytic Leukemia, run by Xcyte Therapies at 4 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 16 inclusion and 14 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 22 Nov 2006. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?
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 22 Nov 2006.
