    Abstract:
    This is an open-label, single-arm, phase 3b study (part of phase 3 development) to evaluate the efficacy and safety of Fortovase-soft gelatin formulation (saquinavir-SGC), combined with zidovudine (ZDV) and lamivudine (3TC), human immune deficiency virus type 1 in (HIV-1)-positive, antiretroviral-naive individuals. Forty-two HIV-1-positive adults with plasma HIV RNA >10,000 copies per milliliter (Roche Amplicor HIV Monitor assay) and CD4 cell count >100 cells/mm(3) were treated with SQV-SGC, 1200 mg three times per day; ZDV, 300 mg; and 3TC, 150 mg each twice per day for 48 weeks. High proportions were drug users (26%), demonstrated psychiatric disorders (alcohol abuse [14%]/depression [14%]), or were inadequately housed (5%). At 48 weeks, 50% of patients achieved viral suppression <400 copies per milliliter with 43% <20 copies per milliliter using an intent-to-treat analysis (missing values counted as virological failures). Corresponding proportions for patients remaining on therapy at 48 weeks were 91% <400 copies per milliliter and 78% <20 copies per milliliter. Most adverse events were mild. Saquinavir-SGC combined with ZDV and 3TC, achieved potent and durable HIV RNA suppression and was well tolerated over 48 weeks in an antiretroviral-naive population including high proportions of individuals considered difficult to treat, such as drug users, people with psychiatric problems and homeless individuals.
