To assess the safety and tolerance of multiple oral doses of 141W94 alone, in combination with 1592U89, and in combination with Retrovir and Epivir, administered to patients with HIV infection as measured by the development of clinical adverse experiences and laboratory test abnormalities. To determine the steady-state pharmacokinetics of 141W94 alone and in combination with 1592U89 after multiple oral dosing. To obtain preliminary evidence of antiretroviral activity of 141W94 alone and in combination with 1592U89, the antiretroviral effect of combined Retrovir/Epivir and the antiretroviral effect of 141W94 when added to Retrovir/Epivir or to 1592U89/Retrovir/Epivir.
To evaluate the safety and tolerance of the combination of adefovir dipivoxil at two comparative doses and nelfinavir plus saquinavir SGC administered orally (Group 1) vs. the combination of adefovir dipivoxil and nelfinavir plus either zidovudine, lamivudine, or stavudine (Group 2) vs. the combination of adefovir dipivoxil and saquinavir SGC plus either zidovudine, lamivudine, or stavudine (Group 3) in HIV-infected patients with prior nucleoside reverse transcriptase inhibitor therapy but no prior exposure to protease inhibitors who have 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) at 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 effect of Viracept in combination with modified antiretroviral therapy on the outcome of cutaneous and mucosal Kaposi's Sarcoma (KS).
To evaluate the safety of topically applied SP-303 gel and to compare the efficacy of SP-303 gel in combination with acyclovir, relative to acyclovir alone, for the treatment of recurrent Herpes Simplex Virus (HSV) 1 and 2 infections, affecting the genital, perianal and neighboring areas, in patients with AIDS.
The purpose of this study is to compare the safety and effectiveness of two dosage schedules for ISIS 2922 in the treatment of advanced cytomegalovirus (CMV) retinitis
The purpose of this study is to see if ALRT1057 is safe and effective in treating patients with AIDS-related Kaposi's sarcoma (KS).
To determine response rate, median time to tumor progression, qualitative and quantitative toxicity and reversibility of toxicity in patients with advanced refractory AIDS-associated Kaposi's sarcoma (KS) administered a 3-hour infusion of paclitaxel every 14 days. To evaluate the clinical benefit of paclitaxel in this patient population by evaluating self-reported responses to the Symptom Distress Scale and by documenting and evaluating any changes in their lymphedema, pain and disfiguring facial lesions.
To explore the antiviral efficacy, tolerability and safety of saquinavir plus zidovudine plus lamivudine.
To evaluate the efficacy (stool frequency) and safety (adverse experiences) of albendazole, administered for 28 days, compared to placebo and for 62 days in open-label fashion, in treating intestinal microsporidiosis in HIV-positive patients. To assess the effect of albendazole on stool volume, weight gain, microsporidial counts in small bowel biopsies, and on the relationship between microsporidial counts in stool and stool frequency and volume. To correlate microsporidial counts with the clinical course of microsporidiosis.
To determine the antimicrobial activity and tolerability of rifapentine alone and in combination therapy in patients with AIDS and disseminated Mycobacterium avium complex (MAC) bacteremia. To determine the pharmacokinetics of rifapentine and its metabolite, 25-desacetyl, alone and in combination therapy. To determine the pharmacokinetics of azithromycin and clarithromycin (and its 14-OH metabolite) in combination therapy.
