A Phase I Study of the Safety and Pharmacokinetics of Recombinant CD4 Immunoglobulin G (rCD4-IgG) in Infants and Children With Documented HIV-1 Infection

• Status: Completed
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

To determine the safety profile, assess pharmacokinetic properties (blood levels), and obtain preliminary indication of the antiviral and immunologic effects of recombinant CD4 immunoglobulin G (CD4-IgG).

CD4-IgG may be effective in blocking HIV transmission and spread, that is, CD4-IgG has antiviral effects. Studies done in adult patients with AIDS and AIDS related complex (ARC) have shown that rCD4 can be safely administered by intravenous bolus, intramuscular or subcutaneous injection. No serious or dose-limiting, drug-related toxicities have been observed to date.
