    Abstract:

    To assess the safety, pharmacokinetics, and antiviral effects of intravenous recombinant CD4 immunoglobulin G (CD4-IgG), a 12-week Phase One study with an optional maintenance phase was performed. Twenty-two subjects with advanced human immunodeficiency virus (HIV) infection were enrolled; 15 subjects completed the initial 12 weeks. CD4-IgG doses were 30, 100, or 300 micrograms/kg weekly; 1,000 micrograms/kg once, twice, or three times per week; or 3,000 micrograms/kg twice weekly. Serum concentrations of CD4-IgG increased linearly with dose, with average peak serum concentrations of 22 micrograms/ml with 1,000 micrograms/kg. CD4-IgG was well tolerated; one patient had self-limited tachycardia and flushing associated with CD4-IgG therapy. No changes were seen in CD4 cell counts, hematologic or coagulation studies, serum chemistries, HIV p24 antigen titers, or plasma HIV titers. No subject developed anti-CD4 antibodies. HIV isolates from five patients had IC90 values that were higher than the peak concentrations of CD4-IgG achieved in those patients. Additional studies that achieve higher CD4-IgG concentrations are necessary to evaluate the antiviral activity of this compound.
