About this study

Official title: PHASE I STUDY OF ANTI-TAC(Fv)-PE38 (LMB-2), A RECOMBINANT SINGLE-CHAIN IMMUNOTOXIN FOR TREATMENT OF TAC-EXPRESSING MALIGNANCIES

RATIONALE: Immunotoxins can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells.

PURPOSE: Phase I trial to study the effectiveness of LMB-2 immunotoxin in treating patients who have leukemia or lymphoma.

Read the detailed description

OBJECTIVES:

  • Assess the therapeutic efficacy and toxicity of the recombinant immunotoxin LMB-2, an anti-Tac murine monoclonal antibody fragment conjugated to a truncated portion of Pseudomonas exotoxin, in patients with Tac-expressing leukemias and lymphomas.
  • Define the pharmacokinetics of LMB-2, including the terminal elimination serum half-life, area under the curve, and volume of distribution.
  • Evaluate, in a preliminary manner, the immunogenicity of LMB-2 in these patients.
  • Determine the effect of LMB-2 on various components of the circulating cellular immune system.

OUTLINE: This is a dose escalation study.

Patients receive LMB-2 immunotoxin IV over 30 minutes on days 1, 3, and 5. Treatment repeats every 15-21 days for up to 10 courses in the absence of disease progression, neutralizing antibodies, or unacceptable toxicity.

Cohorts of 3-6 patients each receive escalating doses of LMB-2 immunotoxin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which no more than 1 patient experiences dose limiting toxicity.

PROJECTED ACCRUAL: A maximum of 40 patients will be accrued for this study.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing LMB-2 immunotoxin in people with Leukemia and Lymphoma, 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?

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 29 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 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 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 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?

On the ClinicalTrials.gov record for NCT00002765, which also lists 5 linked publications.

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 29 Apr 2015.
