Filter by:To compare the efficacy of clarithromycin/ethambutol with placebo or with rifabutin at two different doses in reducing colony-forming units (CFUs) by 2 or more logarithms in patients with Mycobacterium avium Complex bacteremia and maintaining this response until 16 weeks post-randomization. To assess survival and comparative tolerability among the three treatment regimens.
To evaluate the clinical toxicity, safety, and maximum tolerated dose (MTD) of intravenous nystatin in patients with HIV infection. To evaluate the potential anti-HIV activity and clinical pharmacology of intravenous nystatin.
To determine whether there is a pharmacokinetic drug interaction between oral ganciclovir and oral zidovudine (AZT) and between oral ganciclovir and oral didanosine (ddI). To determine whether concurrent administration of probenecid affects the pharmacokinetics of oral ganciclovir. To obtain data on the short-term safety of oral ganciclovir administered concurrently with AZT, ddI, or probenecid in HIV-positive patients.
To evaluate the efficacy of oral ganciclovir in preventing progression to cytomegalovirus (CMV) disease (e.g., CMV retinitis, gastrointestinal CMV disease) in CMV-infected people with HIV infection and CD4 lymphocyte counts <= 100 cells/mm3. To evaluate the efficacy of this drug in reducing morbidity associated with coinfection by both CMV and HIV.
To determine the change in CD4 count after 4 and 8 weeks in HIV-infected patients treated with cimetidine compared to placebo. To observe time-associated trends at weeks 4, 8, 12, and 16 in the change of CD4 counts for patients taking cimetidine for the full 16 weeks. To establish a safety record for cimetidine use in HIV-positive patients.
PRIMARY: To determine whether pentoxifylline changes the self-reported measures of quality of life status, using measures of scores from double-blinded drug withdrawal and drug restart periods. SECONDARY: To measure the changes in monthly CD4 counts, fasting serum triglyceride levels, and weight; to assess the safety of pentoxifylline in HIV-infected persons.
To evaluate the efficacy and safety of two doses of azithromycin given chronically for the treatment of Mycobacterium avium bacteremia in AIDS patients.
To evaluate the efficacy and safety of azithromycin given chronically for the treatment of Mycobacterium avium (MAC) bacteremia in patients failing or intolerant of current available MAC therapy.
Primary: To determine whether the combination of zidovudine/zalcitabine/interferon alfa-n1 (Retrovir/HIVID/Wellferon) can produce complete responses (i.e., CD4 counts return to >= 800 cells/mm3 for more than 24 weeks) in patients with virus sensitive to all three agents. To determine the antiviral effect of the combination therapies as evidenced by measures of quantitative viral load performed at select study centers only. Secondary: To determine the effectiveness of Retrovir/HIVID and Retrovir/HIVID/Wellferon in maintaining or increasing CD4 counts and preventing disease progression as evidenced by the development of an AIDS-defining indicator disease. To determine the effect of these regimens on secondary measures of clinical status (e.g., performance score, weight change, and secondary infections) and on measures of virologic activity such as serum p24 antigen. To assess the safety and tolerance of these regimens.
To evaluate the efficacy and safety of azithromycin given chronically for the treatment of serious nontuberculous mycobacterial infection in patients failing or intolerant of other available therapy.
