Filter by:To determine the pharmacokinetic properties, tolerance and safety of 2 formulations of saquinavir, given in combination with 2 nucleoside antiretroviral drugs (part 1) or in combination with nelfinavir and nucleoside antiretroviral drugs (part 2), in HIV-infected infants and children.
To evaluate the safety and tolerance of adefovir dipivoxil and indinavir administered orally in combination with zidovudine, lamivudine, or stavudine in HIV-infected patients with CD4 cell counts >= 100 cells/mm3 and an HIV-1 RNA baseline copy number >= 5000 copies/ml. To determine the proportion of patients whose plasma HIV-1 RNA level falls below the level of detection (500 copies/ml) by 20 weeks of study therapy and the average reduction in HIV-1 RNA from baseline through study week 20. To evaluate the durability of the antiviral response through 48 weeks of study in patients who continue on study therapy after week 24.
To determine the proportion of patients whose plasma HIV-1 RNA level falls below the level of detection (< 400 copies/ml) at week 24 of study therapy. To determine the absolute change in plasma HIV-1 RNA during the 24 weeks of study treatment. To collect safety data on the treatment regimens. AS PER AMENDMENT 12/12/97: To compare the virologic response of Fortovase (FTV) (Saquinavir) Soft Gel Capsule (SGC) tid plus nucleoside reverse transcriptase inhibitors (NRTIs) versus FTV bid plus NRTIs. Further, to compare the virologic response of FTV tid plus NRTIs versus FTV bid plus Nelfinavir bid plus a NRTI with respect to: the percentage of patients whose plasma HIV-1 RNA level falls below the Amplicor assay level of detection (< 400 copies/ml) at week 24 and week 48.
To investigate the efficacy and safety of RS-79070 when used as induction therapy in patients with newly diagnosed peripheral retinitis. To assess the effects of induction and maintenance level dosing of RS-79070 on CMV viral load, estimated by plasma CMV PCR. To assess the pharmacokinetics of ganciclovir following administration of RS-79070 in the target population.
To evaluate, in HIV-infected patients whose baseline CD4 count is 300 to 750 cells/mm3, whether an antiretroviral treatment regimen based upon clinical evaluation and CD4 counts plus HIV RNA viral load is more effective than a treatment regimen based upon clinical evaluation and CD4 counts without the use of HIV RNA viral load information. To assess relative utility of viral load testing in determining therapeutic choice by the surrogate marker of CD4 cell counts after 48 weeks of therapy. It is hypothesized that among HIV-infected patients whose baseline CD4 count is in the range of 300 to 750 cells/mm3, those patients who incorporate initial and periodic viral RNA measurements in their therapeutic decisions will have higher CD4 counts after 48 weeks than patients whose therapeutic decisions do not incorporate initial and periodic viral RNA measurements.
The purpose of this study is to see if it is safe and effective to treat HIV-infected patients with indinavir (IDV) plus nelfinavir (NFV), 2 anti-HIV medications. It is thought that IDV plus NFV will be a safe drug combination for treating HIV.
To examine the efficacy of saquinavir SGC (soft gel capsules) in combination with other antiretrovirals in HIV-1 infected patients currently treated with saquinavir HGC (hard gel capsules) measured by the absolute change in plasma HIV-1 RNA during the 24 weeks of study treatment.
To evaluate the safety and tolerability of multiple escalating doses of 1263W94 administered orally for 28 days in HIV infected patients with asymptomatic CMV shedding. To obtain preliminary evidence of the in vivo anti CMV activity of different doses of 1263W94 in humans based on quantitative reduction of CMV load in semen and if possible in other biological fluids and to explore the dose response relationship in the anti-CMV activity of 1263W94.
To determine the steady-state pharmacokinetics of 141W94 in combination with saquinavir, indinavir and nelfinavir after multiple oral dosing. To determine the steady-state pharmacokinetics of saquinavir, indinavir, and nelfinavir in combination with 141W94 after multiple oral dosing. To assess the safety and tolerability of multiple doses of 141W94 when combined with saquinavir, indinavir and nelfinavir.
To compare the magnitude and durability of the reduction in plasma HIV RNA in the two treatment groups over the first 12 weeks of treatment. To determine the safety of each of the two treatment groups.
