About this study
Official title: Protocol for a Phase I Study of Intrathecal LMB-7 (Single-Chain Immunotoxin Constructed From Monoclonal Antibody B3-Pseudomonas Exotoxin PE 38) [IND 5863, NSC 658931] in the Treatment of Patients With Leptomeningeal Neoplasms
RATIONALE: LMB-7 immunotoxin can locate tumor cells and kill them without harming normal cells.
PURPOSE: Phase I trial to study the effectiveness of LMB-7 immunotoxin in treating patients who have leptomeningeal metastases metastases.
Read the detailed description
OBJECTIVES: I. Determine the toxicity of intrathecal LMB-7 immunotoxin in patients with leptomeningeal metastases. II. Identify objective therapeutic responses in this group of patients.
OUTLINE: This is a dose escalation study. Patients receive LMB-7 intrathecally on days 1, 3, and 5. Treatment may be repeated every 4 weeks if the patient does not demonstrate HAMA neutralizing antibodies to PE-38 in CSF, has stable or responding disease, and has not experienced greater than grade II toxicity. Three to six patients are entered at each dose level. Dose escalation continues until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience grade 3 or worse toxicity or a neuroradiology toxicity score of 10 or greater.
PROJECTED ACCRUAL: Approximately 15 to 24 patients will be accrued over one year.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing LMB-7 immunotoxin in people with Brain and Central Nervous System Tumors, run by Duke University 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 20 Feb 2013. 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?
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 20 Feb 2013.
