Filter by:This study is being done to find out what women would want in a film vaginal product for human immunodeficiency virus (HIV) prevention, especially what it should look like and how to apply it. The investigators hypothesize that women will prefer a smooth, clear, and rectangular quick-dissolve vaginal film for HIV prevention over a textured, opaque, square quick-dissolve vaginal film.
This study will be a phase I, open label, two arm, fixed sequence crossover study to investigate the effect of rifampin and rifabutin on the steady state pharmacokinetics (PK) of GSK1349572 and the safety and tolerability of GSK1349572 and rifamycin co-administration. Subjects enrolled in Arm 1 will receive GSK1349572 50 mg once daily for 7 days, GSK1348572 50 mg twice daily for 7 days, and GSK1349572 50 mg twice daily in combination with rifampin 600 mg once daily for 14 days. Subjects in Arm 2 will receive GSK1349572 50 mg once daily for 7 days and GSK1349572 50 mg once daily in combination with rifabutin 300 mg once daily for 14 days. Serial PK sampling will be completed following the last dose of each treatment. Safety and tolerability will be assessed throughout the study through assessment of adverse events (AEs), and clinical laboratory tests. This study will be conducted at one center in the US with healthy adult male and female subjects.
GSK1349572 is an integrase inhibitor that is currently in clinical development for the treatment of human immunodeficiency virus (HIV) infection. GSK1349572 is metabolized primarily by uridine diphosphate glucuronosyltransferase (UGT)1A1 with a minor role of Cytochrome P450 (CYP)3A. Hepatic impairment could potentially alter the clearance and plasma protein binding of GSK1349572. This study will evaluate the single dose pharmacokinetics and safety of GSK1349572 in healthy subjects and in subjects with mild or moderate hepatic impairment based on Child-Pugh category. This is a single-dose, open-label, parallel group, two-part, adaptive study in adult males and females with mild or moderate hepatic impairment and matched, healthy control subjects with normal hepatic function. Healthy control subjects (16) will be matched for gender, age, and BMI to the subjects in the mild (8) or moderate (8) hepatic impairment category. In Part 1, approximately 8 subjects with moderate hepatic impairment (cohort 1) and 8 matched, control subjects (cohort 2) will each receive GSK1349572 50 mg as a single dose in the fasted state followed by pharmacokinetic sampling for total concentrations of GSK1349572 in plasma. Free (unbound) plasma concentrations of GSK1349572 will also be evaluated at sparse, selected time points. If the geometric mean total plasma area under the concentration curve (AUC) of GSK1349572 is increased by > 2-fold in moderately impaired subjects compared to matched controls, Part 2 will be conducted to evaluate GSK1349572 pharmacokinetics in another group of subjects with mild impairment (8, cohort 3) and matched, control subjects (8, cohort 4). Vital signs, electrocardiograms (ECGs), and adverse events will be monitored throughout the study. A follow-up visit will occur 7-10 days after the dose of study drug.
ING111762 is a 48 week, randomized, double-blind, active-controlled, multicenter, parallel group, non-inferiority study. The study will be conducted in at least 688 HIV-1 infected antiretroviral experienced, integrase-naïve subjects. Subjects will be randomized 1:1 to receive GSK1349572 50 mg once daily or raltegravir (RAL) 400 mg twice daily, each added to an investigator selected background regimen consisting of at least one fully active agent plus no more than one second single agent which may or may not be active. Antiviral activity, safety, pharmacokinetics (PK), and development of viral resistance will be evaluated.
The purpose of this study is to find ways to improve infant health and survival among infants whose mothers are HIV-infected but who do not themselves have HIV.
With the increasing age of people living with HIV/AIDS, age-induced osteoporosis is likely to be compounded by HIV/AIDS and HAART-associated bone loss. Mechanistically, osteoclasts the cells responsible for bone resorption form under the influence of the key osteoclastogenic cytokine receptor activator of nuclear factor kappa-Β ligand (RANKL). The osteoclastogenic and proresorptive activities of RANKL are moderated by its physiological decoy receptor osteoprotegerin (OPG). Imbalance in the ratio of RANKL to OPG alters osteoclastic bone resorption and lead to osteoporosis. Activated T- and B-cells are a major source of RANKL, while normal physiological B-cells are a major source of OPG. T-cells regulate the production of OPG by B-cells. Thus changes in the immune system induced by HIV/AIDS and/or by HAART could affect B-cell and T-cells RANKL and OPG production. Indeed, data from our group shows that in an animal model of HIV/AIDS, the HIV-1 Transgenic rat, the development of osteoporosis is recapitulated as observed in HIV-infected patients, and B-cell OPG and RANKL production are concurrently down regulated and upregulated respectively. Furthermore, preliminary data in HIV-infected subjects suggests dramatic acute upswing in bone resorption following HAART initiation that peaks at 12 weeks and then declines. Based on these findings, the investigators hypothesize HAART associated bone loss is driven by immune reconstitution. Because this effect of HAART is dramatic in magnitude but short in duration, the investigators propose to apply antiresorptive agent (zoledronic acid, reclast®) to specifically spare patients from this dramatic but acute bone damage.
The purpose of this trial is to assess the non-inferior antiviral activity of GSK1349572 50 mg once daily versus RAL 400mg twice daily over 48 weeks; non-inferiority will also be tested at Week 96. Both GSK1349572 and RAL will be given in combination with fixed-dose dual NRTI therapy (ABC/3TC or TDF/FTC). This study will be conducted in HIV-1 infected ART-naïve adult subjects.
The study is being conducted to evaluate whether African potato, an herbal medicine, can be used together with anti-HIV medicines without affecting the amounts of the anti-HIV medicines in the blood. African potato is an African herbal medicine widely used in Africa, particularly sub-Saharan Africa. Although it has not been proven, it is believed to help boost the immune system. Similar studies have been done on herbal medicines especially those that are used in developing countries. In some cases, the herbal treatments can affect the blood levels of other medicines when the medicines are used together. This study will measure the effect of African potato on lopinavir/ritonavir (Kaletra®), a common anti-HIV medicine. Lopinavir/ritonavir is approved by the United States Food and Drug Administration (FDA). The information obtained from this study will tell us if African potato and anti-HIV treatments can be used together to treat HIV infected patients in Africa and other resource poor regions.
This study examines the impact of fosamprenavir as part of an ART on virological, immunological and clinical parameters of genotype 1 HCV infection in HIV co-infected subjects. Fosamprenavir could have a direct or immune-mediated activity against HCV. If this is shown to be true, changes in HCV viral load or biological characteristics could be demonstrated.
This study is designed to develop and evaluate a set of non-virologic diagnostic algorithms to monitor HIV-exposed children of unknown infection status for treatment eligibility during the first year of life. The results of this cross sectional study are expected to be used in development of a series of non-virologic algorithms to determining treatment eligibility among HIV-exposed children in settings where polymerase chain reaction (PCR) testing is not available and to guide the judicious use of PCR testing among HIV-exposed children in settings where PCR is available. These results will directly inform program implementation in Zambia.
