Safety, Tolerability, and Anti-HIV Activity of PEG-Intron in HIV-Positive Children

28. oktober 2021 opdateret af: National Institute of Allergy and Infectious Diseases (NIAID)

Safety, Tolerability, Antiviral Activity, and Pharmacokinetics of PEG-Intron in HIV-1 Infected Children

The purpose of this study is to see if PEG-Intron is safe and tolerated when given to children, to see how much gets into the blood and how long it stays in the blood, and to see how well it works to reduce viral load (level of HIV in the blood).

PEG-Intron is an experimental drug that works differently than other anti-HIV medications. It decreases the ability of HIV to infect the T cells (a special type of cell that helps fight infection). PEG-Intron has been approved by the Food and Drug Administration (FDA) to treat hepatitis C in adults, but in this study, it is being used as an investigational agent for the treatment of HIV/AIDS. It has not been tested in children before and experience with PEG-Intron in adults is limited. (This protocol has been changed to reflect FDA approval of PEG-Intron for treating hepatitic C in adults.)

Detaljeret beskrivelse

The current optimal clinical management of HIV infection involves therapy with combinations of nucleoside and nonnucleoside reverse transcriptase inhibitors and HIV protease inhibitors. These regimens, though effective, do not completely eliminate HIV and the development of drug resistance is a major clinical problem. Interferons have been proposed as a possible treatment of HIV. Interferon-alfa inhibits HIV replication in vitro, and HIV-infected patients appear to have reduced production of interferons. Previous short-term clinical studies in adults showed anti-HIV activity, although there were safety and tolerability problems associated with the higher dose regimens used. This study will utilize a rising multiple-dose design to assess the safety, tolerability, and pharmacokinetics of single and multiple doses of PEG-Intron in HIV-infected children.

In a dose-escalation study, patients add weekly PEG-Intron to their antiretroviral therapy for up to 6 weeks. The first 2 doses are received in the clinic where parents/guardians are trained to administer injections, and succeeding doses are given at home.

Patients are enrolled from 2 cohorts. An older cohort of ages 2 to 16 years receives PEG-Intron at the lowest drug level. If the dose is tolerated, patients are added and if safety criteria are met, patients are enrolled in the next higher dose level. The dose level will be increased similarly for up to 4 doses. An optimal dose level is chosen.

Cohort II patients are a younger group ranging from 3 months to under 2 years of age. Patients initially receive the next lower PEG-Intron dose to the optimal dose identified in Cohort I [AS PER AMENDMENT 07/23/01: or 1 microg/kg if the optimal dose proves to be 1 microg/kg]. If this dose is safely tolerated, additional patients are added. If this dose level meets safety criteria, patients are enrolled to receive the optimal dose level. Patients are evaluated with the same safety criteria as Cohort I. Patients in both cohorts who have at least a 0.5 log reduction in HIV RNA at 28 days of treatment are offered continued treatment for a total of 60 weeks.
