Filter by:To provide trimetrexate glucuronate to immunosuppressed patients with Pneumocystis carinii pneumonia (PCP) for whom this investigational compound could provide significant medical benefit.
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 assess the safety and tolerance of curdlan sulfate, as well as its anti-HIV activity, in HIV-infected patients with CD4 T-lymphocytes less than 500 cells/mm3, using first single doses and then, after FDA review, daily doses for 7 days.
To determine the tolerance and side effects of a combination of lentinan and didanosine (ddI) compared with ddI alone. To determine whether the combination of lentinan and ddI produces a significant immunorestorative effect within the study observation period (6-12 months) as measured by an increase in one or more of the following: neutrophil count and activity, T-cell subsets, and a decrease in p24 antigen.
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 time course of development of resistance to atevirdine mesylate ( U-87201E ) in patients with HIV isolates showing in vitro resistance to zidovudine ( AZT ). To determine the genotype changes in HIV reverse transcriptase associated with in vitro AZT resistance to U-87201E. To determine the genotype and phenotype effects of treatment with a nondideoxynucleoside agent on the alterations of the HIV-1 population associated with in vitro AZT resistance. To determine whether serial passage of patient pre-drug HIV isolates in the presence of U-87201E will generate the resistant mutants that may subsequently emerge in the patients.
To compare the toxicity profiles (severity and time to onset from initiation of therapy) between daunorubicin (liposomal) and combination chemotherapy with doxorubicin/bleomycin/vincristine (ABV), with both regimens administered in combination with antiretroviral therapy. To compare the duration of responses, response rates, and times to response.
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.
