About this study

Official title: Phase I Study of Recombinant BL22 Immunotoxin in Patients With CD22-Positive B-Cell Non-Hodgkin's Lymphoma or Chronic Lymphocytic Leukemia

RATIONALE: The BL22 immunotoxin can locate tumor cells and kill them without harming normal cells.

PURPOSE: Phase I trial to study the effectiveness of the BL22 immunotoxin in treating patients who have non-Hodgkin's lymphoma or chronic lymphocytic leukemia.

Read the detailed description

OBJECTIVES:

  • Determine the toxicity and therapeutic efficacy of recombinant BL22 immunotoxin in patients with CD22-positive B-cell non-Hodgkin's lymphoma or chronic lymphocytic leukemia.
  • Determine the pharmacokinetics, including the terminal elimination serum half-life area under the curve and volume of distribution, of recombinant BL22 immunotoxin in these patients.
  • Determine the immunogenicity of recombinant BL22 immunotoxin in these patients.
  • Determine the effect of recombinant BL22 immunotoxin on various components of the circulating cellular immune system in these patients.

OUTLINE: This is a dose-escalation study.

Patients receive recombinant BL22 immunotoxin IV over 30 minutes on days 1, 3, and 5. Patients may be retreated at least every 20 days for up to 25 courses in the absence of disease progression and sufficient neutralizing antibodies.

Cohorts of 3-6 patients receive escalating doses of recombinant BL22 immunotoxin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.

PROJECTED ACCRUAL: A total of 40 patients will be accrued for this study within 2 years.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BL22 immunotoxin, antibody therapy and biological response modifier therapy in people with Leukemia and Lymphoma, run by National Cancer Institute (NCI) 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?

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The record says: withdrawn, as of the sponsor's last update on 28 Apr 2015. 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 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.

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 was withdrawn before enrolling participants, so there are no results.

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 28 Apr 2015.
