To determine the tolerance of HIV-infected patients to TID oral doses of FIAU syrup at 4 different dose levels. To determine the peak and trough blood levels of FIAU and its metabolites during two weeks of oral dosing with FIAU. The pyrimidine nucleoside analog FIAC and its primary deaminated uracil metabolite FIAU are highly and specifically active compounds in vitro against several herpes group viruses, particularly herpes simplex virus (HSV) types 1 and 2, varicella zoster (VZV), and cytomegalovirus (CMV), as well as hepatitis B virus (HBV). Since FIAU is the primary metabolite of FIAC and the administration of FIAU simplifies the metabolism of FIAC, it is anticipated from clinical studies of FIAC that FIAU will be tolerated at least as well as FIAC. A single-dose, pharmacokinetic (blood level) study showed that FIAC, when taken orally, is readily absorbed into the bloodstream, and most of it is converted to FIAU. Daily oral doses are expected to provide concentrations of FIAU exceeding the in vitro minimum inhibitory concentration for nearly all the herpes group viruses.
To evaluate the effectiveness of atovaquone (566C80) compared to a standard antipneumocystis agent, (SMX/TMP), for the treatment of mild to moderate Pneumocystis carinii pneumonia (PCP) in AIDS patients. To compare the safety of short-term (21 days) treatment with 566C80 and SMX/TMP in AIDS patients with an acute episode of PCP. Standard therapies for acute treatment of PCP involve either SMX/TMP or pentamidine isetionate. Although both treatments are equally effective, side effects prevent completion of therapy in 11-55 percent of patients.
To assess the safety and to evaluate the anti-HIV effect of low-, moderate-, and high-dose schedules of zidovudine (AZT) plus didanosine (ddI) versus ddI alone in asymptomatic HIV-infected patients. Because of the failure with long-term (more than 1 year) use of, frequency of toxicity from, and drug resistance to AZT, drug combinations need to be developed to enable lower, less toxic doses of AZT to be used and to slow or prevent the development of resistance, while providing at least the same effectiveness.
To compare the safety and effectiveness of orally administered didanosine (ddI) with high dose orally administered zidovudine (AZT) in patients who develop or exhibit progression of the AIDS dementia complex (ADC) and who have not previously been intolerant to AZT at doses of up to 1000 mg/day. HIV-infected or AIDS patients may develop ADC which causes damage to the nervous system. ADC may be caused by some action of the AIDS virus on the nervous system, although similar problems can be caused by other infections because the AIDS virus lowers the body's ability to fight other infections. It is important to determine whether symptoms are due to ADC or to some other infection since treatment varies for different conditions. AZT has been shown to be beneficial to people with ADC although its effectiveness has only been studied in a small number of patients. Studies suggest that higher doses of AZT are more likely to be effective than standard doses in improving symptoms of ADC.
To determine the impact of dose intensity on tumor response and survival in patients with HIV-associated non-Hodgkin's lymphoma (NHL). HIV-infected patients are at increased risk for developing intermediate and high-grade NHL. While combination chemotherapy for aggressive B-cell NHL in the absence of immunodeficiency is highly effective, the outcome of therapy for patients with AIDS-associated NHL has been disappointing. Treatment is frequently complicated by the occurrence of multiple opportunistic infections, as well as the presence of poor bone marrow reserve, making the administration of standard doses of chemotherapy difficult. A recent study was completed using a low-dose modification of the standard mBACOD (cyclophosphamide, doxorubicin, vincristine, bleomycin, dexamethasone, methotrexate ) treatment. A 46 percent response rate was observed in patients treated with this combination of chemotherapeutic agents, with a number of durable remissions and reduced toxicity when compared to previous experience with more standard treatments. A subsequent study showed similar effectiveness using a lower dose of methotrexate administered on day 15. It is hoped that the use of sargramostim (granulocyte-macrophage colony-stimulating factor; GM-CSF) will improve bone marrow function and allow for administration of a higher dose of chemotherapy.
To define the toxicity and maximum-tolerated dose of weekly oral etoposide (VP-16) in patients with AIDS-related Kaposi's sarcoma; to determine the clinical pharmacology of orally administered VP-16 in AIDS patients. A secondary objective is to obtain preliminary data for determining the effect of oral VP-16 on Kaposi's sarcoma. VP-16 is an antitumor agent. Previous problems with VP-16 include the route of administration and the toxicities. VP-16 has been given intravenously for 3 consecutive days in a 21-day cycle for lung cancer and testicular cancer. VP-16 has also been used in lymphoma therapy. Oral VP-16 would eliminate the need for an intravenous catheter and so a patient could avoid the pain, inconvenience, and potential complications associated with medications administered intravenously. The relative ease of outpatient administration and the potentially significant antitumor activity of oral VP-16 motivates this study. The possibility of weekly drug administration is the other focus of this study.
To determine if a pharmacokinetic (blood level) interaction exists between zidovudine (AZT) and oxazepam in the HIV-infected patient. Benzodiazepines (such as oxazepam) are among the most frequently prescribed class of drugs and are commonly used therapeutically for patients with chronic disease. This study is important because of the potential for toxicity resulting from a reaction between AZT and benzodiazepines and the likelihood of frequent use of the combination of these drugs in patients with HIV infection.
To facilitate the use of zidovudine (AZT) in children who are 3 months to 12 years of age who are HIV-infected and either symptomatic or have a CD4 cell count < 400 cells/mm3 and to monitor adverse effects of AZT. Previous studies with pediatric patients have shown improvements in clinical, immunologic, and virologic parameters with administration of AZT.
To determine the safety profile, assess pharmacokinetic properties (blood levels), and obtain preliminary indication of the antiviral and immunologic effects of recombinant CD4 immunoglobulin G (CD4-IgG). CD4-IgG may be effective in blocking HIV transmission and spread, that is, CD4-IgG has antiviral effects. Studies done in adult patients with AIDS and AIDS related complex (ARC) have shown that rCD4 can be safely administered by intravenous bolus, intramuscular or subcutaneous injection. No serious or dose-limiting, drug-related toxicities have been observed to date.
To determine the safety of polyethylene glycolated IL-2 (PEG IL2) administered weekly or biweekly (per amendment) in a setting of oral zidovudine (AZT). To determine the effect of PEG IL2 in combination with AZT on parameters assessing the immune system as well as HIV virus and antibody titers. To evaluate a chronic dosing study phase offered to patients who complete the initial 25-week regimen. Recent research has focused on enhancing cell-mediated immunity and reducing or eliminating viral replication (reproduction and growth). A main thrust of current treatment is the combination of antiviral drugs that may be more effective when combined than when each is used alone.
