Filter by:To evaluate the single-dose pharmacokinetic profile and acute toxicity of bis-POM PMEA ( adefovir dipivoxil ) in HIV-1 infected children, and to determine whether age-related differences exist. To ascertain dosages that may be suitable for a multiple-dose evaluation in this patient population. Although the oral bioavailability of PMEA ( adefovir ) is low, the prodrug bis-POM PMEA has resulted in increased bioavailability in adult patients in clinical trials. However, the safety and pharmacokinetic patterns of drugs in infants often differ from those of adults and the direction of the variation is not predictable. This study will assess these parameters of bis-POM PMEA in children.
To assess the efficacy, safety, and tolerability of recombinant human nerve growth factor ( rhNGF ) in the treatment of HIV-associated sensory neuropathy. AS PER AMENDMENT 5/6/97: To compare the change in viral load between the double-blind phase baseline and week 4 in placebo and active rhNGF recipients. To ensure that rhNGF does not induce an increase in viral load compared with viral load changes seen with placebo. Up to now, treatments for HIV-associated sensory neuropathy have been symptomatic, relying on pain-modifying agents or membrane-stabilizing drugs. Because nerve growth factor is important in the development and maintenance of sympathetic and sensory neurons and their outgrowths, it is proposed that recombinant human nerve growth factor may provide a specific restorative treatment for HIV-associated painful sensory neuropathy.
To determine the clinical efficacy of indinavir sulfate or placebo in combination with zidovudine ( AZT ) and lamivudine ( 3TC ) in AIDS patients. Protease inhibitors such as indinavir sulfate may be effective in patients with advanced HIV disease who have received prior AZT therapy. Since studies suggest that triple drug therapy may have an advantage over both monotherapy and two drug therapy, the combination of indinavir sulfate with AZT and 3TC should be evaluated.
To evaluate viral load in the blood stream of HIV-infected patients during a 28-day washout following cessation of long-term zidovudine ( AZT ) therapy. Because viral load (amount of HIV RNA in the plasma) is often used as a measure of the effectiveness of new antiretroviral drugs in clinical trials, a washout period, or cessation of current antiretroviral regimens, is commonly required for study entry to allow for a drug-free steady state of viral load prior to initiation of the new drug. However, the kinetics of the viral rebound following drug withdrawal has not been sufficiently studied, and the proper duration of washout is an estimate.
To assess the pharmacokinetics, safety, and toxicity of intravenous and oral didanosine (ddI) administration in third trimester pregnant women who are HIV positive but are either intolerant or resistant to zidovudine (AZT). To collect data on infant toxicity following maternal treatment with ddI during the third trimester of pregnancy. AZT may not be the optimal antiretroviral agent for all pregnant women requiring therapy for HIV infection. Although ddI has been approved for use in HIV-infected adults and older children, the safety and pharmacokinetics of ddI in pregnant women has not yet been determined.
To evaluate the efficacy, safety, and pharmacokinetics of lamivudine (3TC) combined with zidovudine (AZT), stavudine (d4T), or didanosine (ddI) in comparison with d4T or ddI monotherapy in HIV-infected patients with no prior nucleoside therapy. 3TC may be uniquely effective in combination with AZT due to the interaction of AZT and 3TC resistance mutations. One explanation is that the M184V mutation, which confers resistance to 3TC, suppresses AZT resistance. This benefit of 3TC may not extend to combination therapy with other nucleoside analogs.
The purpose of this study is to see if it is safe to give Varivax to HIV-positive children and whether it protects children from infection. Varivax is a vaccine against varicella zoster virus (VZV), the virus that causes chickenpox (varicella) and shingles (zoster). VZV can cause many serious complications in HIV-infected children. Varivax is a VZV vaccine that has been approved for use in healthy children. More research is needed to find out how this vaccine will affect HIV-infected children.
To compare the safety and efficacy of sevirumab (MSL 109; Protovir), human anti-cytomegalovirus (CMV) monoclonal antibody, plus active primary treatment versus placebo plus active primary treatment in AIDS patients with newly diagnosed and relapsed CMV retinitis. Ganciclovir and foscarnet are used for treatment of CMV retinitis, but cause hematologic toxicity and nephrotoxicity, respectively. Despite continued maintenance therapy with these drugs, relapse occurs in 85 percent of patients within 4 months. Studies suggest that MSL 109, a human monoclonal antibody, when given with either ganciclovir or foscarnet, may increase initial response and prolong time to progression in patients with CMV retinitis.
The purpose of this trial is to determine the safety and immunogenicity of an HIV-1 pseudovirion vaccine given at one antigen dose alone and in combination with each of two different adjuvants using two immunization schedules. The pseudovirions are virus-like particles generated by in vitro production of HIV-1 viral proteins which are capable of assembly into particles. The presence of gag gene products in addition to envelope glycoprotein should assist in humoral and cellular immunologic responses to internal HIV-1 viral proteins. The pseudovirion vaccine has been tested in preclinical trials in mice, guinea pigs, rabbits, and nonhuman primates with good safety and immunogenicity profile.
To determine the safety and tolerance of methotrexate in HIV-infected patients. To determine the dose effective in modulating key markers of immune activation. To determine a dose suitable for Phase II or III evaluation in HIV-infected patients. In HIV infection, complete immunological clearance of the foreign antigen does not occur, resulting in chronic immune activation. Because chronic immune activation may contribute to disease progression in HIV infection, immunomodulators may have therapeutic value in early HIV disease prior to development of opportunistic infections. The clinical benefits of methotrexate appear to derive from an anti-inflammatory effect; thus, it may reduce the state of chronic immune activation.
