Active clinical trials for "HIV Infections"

To assess the safety, tolerance, and steady-state pharmacokinetics of multiple oral doses of 935U83 administered to patients with HIV infection. To obtain preliminary evidence of antiretroviral activity of 935U83. To prospectively evaluate the emergence of in vitro drug resistance. To determine the effects of 935U83 dosing on CD4+ cell counts.

To assess whether high dose or low dose atovaquone suspension is more effective than aerosolized pentamidine as prophylaxis against Pneumocystis carinii pneumonia (PCP) in high-risk HIV-infected patients. To compare the safety of chronic administration of the three regimens in patients with advanced HIV disease. To determine the relationship between steady state atovaquone plasma concentrations and prophylactic efficacy against PCP.

To evaluate the tolerance and immunologic and virologic effects of multidrug combinations of antiretrovirals in patients with HIV infection. Specifically, to evaluate zidovudine/zalcitabine ( AZT / ddC ) alone or in combination with either nevirapine or saquinavir ( Ro 31-8959 ). Administration of three-drug combinations for treatment of HIV infection is preferred over monotherapy or duotherapy. A system has been designed to rapidly evaluate current multidrug combinations of antiretrovirals and allow the addition of new agents as they become available.

To compare the antiviral effect of stavudine ( d4T ) versus placebo in patients with evidence of recent HIV infection. Also, to compare the immunologic effects and effects on quality of life of d4T in these patients.

To evaluate safety and immune response in HIV-infected patients treated with multiple injections of APL 400-003 vaccine. PER 2/27/96 AMENDMENT: To evaluate the safety of the vaccine when administered via the Biojector 2000 Needle-Free Injection Management System. Facilitated DNA inoculation, a new type of DNA vaccine, involves direct injection of non-infectious HIV genes into a patient's muscle, along with agents that promote uptake of the genes into host cells. Host cells that have taken up these genes then produce viral proteins in a form that elicits immune responses in the form of antibodies, killer T-cells, and helper T-cells. The safety of this new vaccine approach needs to be assessed. PER 2/27/96 AMENDMENT: The Biojector 2000 provides an option for delivering the vaccine without a needle and employs a single-use syringe to avoid cross-contamination.

The purpose of this study is to see if it is safe and effective to give indinavir sulfate plus stavudine to HIV-infected patients who have already been treated with zidovudine.

The purpose of this study is to see if the coated-capsule form of didanosine (ddI) is as safe and absorbed by the body as well as the chewable-tablet form of ddI. Didanosine (ddI) is an anti-HIV drug. The effectiveness of ddI can be lowered by acid in the stomach. To prevent this, patients take antacids with ddI. The coated-capsule form of ddI may replace the need for antacids.

The purpose of this study is to see if it is safe and effective to give an anti-HIV drug combination containing indinavir and ritonavir to HIV-positive patients who have failed previous treatment with protease inhibitors.

To evaluate the tolerance, safety, and effectiveness of Viramune in preventing clinical AIDS progression events or death when used in combination with Lamivudine and background nucleoside therapy.

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.
