About this study
Official title: A Phase I/II Study of T-20, a Fusion Inhibitor, in HIV-1 Infected Children
The purpose of this study is to determine the best dose of T-20, a new anti-HIV drug, to treat HIV-infected children.
T-20, unlike other anti-HIV medications, lessens the ability of HIV to infect certain cells (T cells) in the body. Doctors hope to better treat HIV by adding T-20 to anti-HIV drug combinations that include 1 or 2 nucleoside reverse transcriptase inhibitors (NRTIs) plus a nonnucleoside reverse transcriptase inhibitor (NNRTI) and/or a protease inhibitor (PI).
Read the detailed description
T-20 is the first drug to be developed which specifically inhibits the function of the gp41 transmembrane glycoprotein. By inhibiting the essential protein-protein surface interaction, T-20 is able to block the process of virus-to-host cell membrane fusion. Combination antiretroviral regimens (reverse transcriptase inhibitors plus PIs) have benefited many HIV patients, but heavily pretreated patients often develop multi-drug resistance via multiple gene mutations. A pharmacologic agent, such as T-20, that is effective at an alternative point in the virus replication cycle will make a valuable addition to the treatment of HIV infection.
This Phase I/II open-label, dose-escalating, randomized study is divided into 2 parts. Patients may participate in Part A and/or Part B. Part A (single dosing): 12 patients are sequentially assigned to receive 1 of 3 doses of T-20 given once on Day 0 by SC injection into the abdomen, deltoid area, or anterior aspect of the thigh and once on Day 1 by IV infusion. Provided safety criteria are met, patients who complete Part A, or new enrollees who did not participate in Part A, enroll in Part B. Doses for Part B are determined by pharmacokinetic data obtained in Part A. [AS PER AMENDMENT 4/20/00: Current data has now projected a pediatric dose. Each child will move to chronic dosing in Part B provided the child has no Grade 3 or higher toxicity to study drug through Day 7 in Part A.] Part B (multiple dosing): Patients are randomly assigned to 1 of 3 dose cohorts to receive 24 weeks [AS PER AMENDMENT 12/7/00: 48 weeks] of treatment (optional extension to 48 weeks [AS PER AMENDMENT 12/7/00: 96 weeks]) with bid SC injections of T-20. Cohort 1 receives the dose identified in Part A (Dose 1) as the lowest dose that is well tolerated and that achieves the target trough plasma concentration. Cohort 2 receives the next higher dose from Dose 1 (Dose 2). Cohort 3 receives either Dose 1 or Dose 2, depending on the tolerability and antiviral activity of each dose. [AS PER AMENDMENT 4/20/00: Cohort 1 receives 30 mg/m2 SC bid (Dose 1); Cohort 2 receives 60 mg/m2 SC bid (Dose 2); and Cohort 3 receives Dose 1 or 2 SC bid.] On Day 7 of T-20 dosing, children begin a new antiretroviral therapy regimen chosen by the site investigator based on study parameters. (Abacavir and amprenavir are not allowed for this regimen.) [AS PER AMENDMENT 1/6/00: Abacavir and amprenavir are now allowed.] The first injection will be given in the clinic and a parent/guardian will be trained to give successive injections. [AS PER AMENDMENT 4/20/00: The 2 doses given prior to obtaining trough levels on Days 1 and 7 must be directly observed by medical personnel.] Patients undergo clinical and laboratory evaluations to monitor viral load, HIV-related symptoms, and pharmacokinetics at time points throughout the study. Patients participating in Part A are evaluated at the clinic on Days 0, 1, and 7. Patients participating in Part B are evaluated at the clinic 6 times during the first 3 weeks and then every 4 weeks through Week 24. [AS PER AMENDMENT 12/7/00: Patients participating in Part B are evaluated at the clinic 6 times during the first 3 weeks, every 4 weeks through Week 24, and then every 8 weeks through Week 48.]

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Enfuvirtide in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 25 sites in 2 countries.
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 7 inclusion and 6 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 1 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 25 sites in United States, Puerto Rico. 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 NCT00001118, which also lists 4 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 1 Nov 2021.
