A preliminary evaluation of nelfinavir mesylate, an inhibitor of human immunodeficiency virus (HIV)-1 protease, to treat HIV infection.

A phase I/II dose-ranging open-label 28-day monotherapy study of the safety, pharmacokinetics, and antiviral activity of nelfinavir mesylate (Viracept), an inhibitor of human immunodeficiency virus (HIV)-1 protease, was done in 65 HIV-1-infected subjects. After 28 days, 54 responding subjects entered an open-label extension that allowed for the addition of nucleoside inhibitors of reverse transcriptase and dose escalation to maintain durability. The drug was well-tolerated and demonstrated robust antiviral activity, with demonstrable superiority of the 750 mg and 1000 mg three times daily regimens. Thirty subjects who continued to receive therapy at 12 months attained a persistent 1.6 log10 reduction in HIV RNA, accompanied by a mean increase in CD4 cells of 180-200/mm3. Studies of viral genotype and phenotype after virus rebound revealed that the initial active site mutation allowing for nelfinavir resistance is mediated by a unique amino acid substitution in the HIV-1 protease D30N, which does not confer in vitro phenotypic cross-resistance to the currently available protease inhibitors.[1]
