Filter by:To determine if HIV hyperimmune globulin (HIVIG) given to HIV-positive pregnant women during the second and third trimester of pregnancy reduced the likelihood of maternal-fetal HIV transmission. Conducted in collaboration with the National Institute of Child Health and Human Development and the National Institute of Allergy and Infectious Diseases. The trial was Pediatric ACTG Protocol 185.
To determine whether administration of human recombinant erythropoietin (REPO) improved or eliminated the anemia seen in human immunodeficiency virus (HIV) infected patients after therapy with zidovudine (ZDV).
To study the safety, toxicology, and activity of Peptide T (D-Ala-1-peptide-T-amide) in humans and to find out more about the ability of peptide T to prevent, halt, and/or reverse AIDS-associated immunologic disturbances. Recent information suggests that the central nervous system (CNS) is often impaired in HIV-infected individuals. The dysfunction of the CNS may be either a direct or an indirect result of HIV infection. One method to prevent HIV infection is to block entry of the virus into the cells of the body. Peptide T shows laboratory evidence of blocking the entrance of HIV into cells that are susceptible to HIV infection. Studies that have been done indicate that peptide T is nontoxic in the doses that are used in this study. AIDS patients with minimal (group 1) or moderate (group 2) cognitive dysfunction (mental impairment) receive an increasing schedule of three dosage levels of peptide T. All patients receive an intravenous (IV) dose of peptide T for 10 days followed by the intermediate dose and then the highest dose, each intravenously for 10 days. Following successful completion of 3 IV doses, four patients participate in an intranasal pharmacokinetic (blood level study) dosage trial of 3 doses (different from IV) of peptide T once for each of 3 successive days. Follow-up continues for up to 1 year.
To evaluate the chemical efficacy and safety of intranasally administered peptide T on neurocognitive function in HIV seropositive individuals. Previous studies have shown that treatment with peptide T can result in cognitive improvement in HIV-infected patients. Patients are randomized to receive either peptide T or placebo for the first 6 months. All patients then receive open-label peptide T for approximately 6 additional months. Neuropsychologic tests are used to determine drug effects.
To study the safety and toxicity of intranasal peptide T (D-Ala-1-peptide-T-amide) in humans, and to find out how quickly and how much of a given dose enters the bloodstream and how quickly it leaves the bloodstream. To obtain information on the ability of intranasal peptide T to prevent, halt, and/or reverse the effects of AIDS on the central nervous system. Studies have shown that AIDS is caused by a retrovirus. This virus works by inactivating or destroying human CD4 cells (which are part of the human immune system). This in turn leads to the observed immunologic defects and related illnesses, including HIV encephalopathy (disease of the brain). One method of preventing AIDS is to prevent HIV from entering the cell. HIV binds to the receptor CD4 site. Peptide T also binds to this site, and thus by competing for that site, can block the binding of the virus to its receptor. Preliminary animal and human studies indicate that peptide T is safe at the doses selected for this trial. Thirty patients with AIDS or AIDS related complex (ARC) are entered into the study to receive an increasing schedule of three dosage levels of intranasal peptide T for 12 - 16 weeks followed by a 1-month off-drug follow-up period and a subsequent 1-month return to the drug. All patients receive an initial intravenous test dose of peptide T. The test dose is administered over 1 hour, followed by an observation period of 8 hours in the outpatient clinic.
To monitor trends over time, in the incidence of CMV retinitis and other ocular complications of AIDS To determine the effect of highly active anti-retroviral therapy (HAART)-induced immune status on the risk of developing CMV retinitis and other ocular complications of AIDS To determine the characteristics (clinical, virologic, hematologic, and biochemical) of a population at high risk for CMV retinitis and other ocular complications of AIDS To evaluate the effects of treatments for CMV retinitis and other ocular complications on visual function, quality of life, and survival.
To compare the newest CMV retinitis drug, cidofovir, with a regimen of the ganciclovir intraocular device plus oral ganciclovir with respect to efficacy in preventing vision loss. To compare a treatment regimen that incorporates highly active local therapy (ganciclovir device) with a treatment regimen that does not.
To test and evaluate the efficacy and safety of intravenous cidofovir (Vistide, previously known as HPMPC) for the treatment of retinitis.
To evaluate the relative safety and efficacy of ganciclovir and foscarnet as initial treatment of patients with cytomegalovirus (CMV) retinitis.
To evaluate the efficacy and safety of a human anti-CMV monoclonal antibody, MSL-109, as adjunct therapy for controlling CMV retinitis.
