Filter by:Objectives: Primary: Safety and immunogenicity of MVA.HIVA vaccine in 20-week-old healthy Kenyan infants born to HIV-1-infected mothers. Secondary: - HIV-1 immunogenicity comparison between MVA.HIVA and age-matched unvaccinated control arms in each cohort (breastfeeding or formula feeding) - HIV-1 immunogenicity comparison between breastfeeding and formula feeding infants receiving MVA.HIVA - HIV-1 immunogenicity comparison between breastfeeding and formula feeding infants in the age-matched unvaccinated control group - Comparison of responses to certain Kenyan Extended Programme on Immunization (KEPI) vaccines (OPV, DTP, HBV, and HiB) between MVA.HIVA versus age-matched unvaccinated controls in each cohort, between breast versus formula feeding infants in the age-matched unvaccinated control group, and between breast versus formula infants receiving MVA.HIVA - Comparison of immune activation and phenotypic profile of lymphocytes between breast and formula feeding infants in each cohort (MVA.HIVA and age-matched unvaccinated control) - Build capacity for Infant HIV-1 Vaccine Clinical Trials Centre in Nairobi, Kenya.
The purpose of this study is to provide etravirine (ETR) through this trial until participants can be switched to locally available ETR-based treatment regimens (that is, commercially available and reimbursed, or accessible through another source [example, access program or government program]), or local standard of care, as appropriate.
Based on the investigators previous study, seventy-four of 786 HIV-1 isolates (9.4%), collected between 1999 to 2006, harbored one or more primary mutations associated with antiretroviral resistance to reverse-transcriptase inhibitors (RTIs) or protease inhibitors (PIs) in naïve patients. However, the drug resistance profiles for the HIV-1 integrase gene is unclear. Three objectives are proposed: 1. To investigate and compare the drug resistance profiles for the HIV-1 integrase gene between experienced and naive patients, who has not being exposed to Raltegravir. 2. To investigate and compare the drug resistance profiles for the HIV-1 integrase gene between different subtypes (subtype B, CRF01_AE and CRF07_BC). 3. To identify potential amino acid mutations in the integrase gene, which might affect the efficacy of Raltegravir.
This laboratory-based sub-study of ATN 061 and ATN 071 will examine the effect of early treatment followed by treatment de-intensification to atazanavir/ritonavir (ATV/r) monotherapy on steady-state frequencies of replication-competent CD4+ T cell Human Immunodeficiency Virus (HIV)-1 reservoirs or cell-associated infectivity (CAI) and persistent low-level viremia (LLV), and their contribution to successful long-term control of HIV-1 replication among HIV-1 infected adolescents and young adults.
Aim of the study is to gain more knowledge about efficacy of CELSENTRI® in daily clinical practice and obtain information about the quality of life of patients using CELSENTRI®.
This three stage study will evaluate the safety and tolerability of MRKAd5 HIV-1 Gag Vaccine. In Stage I subjects will be randomized to receive the vaccine at 1x10^9 viral particles/dose (vp/d) or placebo. In Stage II subjects will be randomized to receive the vaccine at 1x10^10 vp/d or placebo. In Stage III subjects will be randomized to receive the vaccine at 1x10^9 vp/d, at 1x10^10 vp/d, or placebo. Immunogenicity of the single dose regimen of MRKAd5 HIV-1 Gag Vaccine will also be measured.
The goal of this study is to understand the safety, tolerability and immunogenicity of the Merck Trivalent Adenovirus Serotype 5 HIV-1 gag/pol/nef Vaccine (MRKAd 5 HIV-1 gag/pol/nef) vaccine in healthy human volunteers compared to placebo. The study will also evaluate a number of dose levels and the necessity for and timing of booster injections.
The investigators seek to determine whether Virco®TYPE HIV-1 provides benefits equivalent to those provided by local expert review. The investigators propose that clinic patients of the Ruth M. Rothstein CORE Center who are having genotypic testing performed will be randomized in a 1:1 fashion to local expert review and to Virco®TYPE HIV-1. Results of either method will be shared with primary HIV care providers. Patient outcomes will be reviewed at a time point equal to or greater than 2 months and 6 months following the change in antiretroviral medications following the testing
The purpose of the study is to determine the safety, tolerability and plasma pharmacokinetics (pk) (i.e., the levels of TMC558445 circulating in your blood over time) of increasing single oral doses of TMC558445 and of multiple increasing oral doses followed by a single dose of TMC310911 to assess the potential boosting effect on the latter compound. In this study, two investigational new drugs are involved, TMC558445 and TMC310911. The study has been amended as follows: TMC558445 will be administered either twice a day (b.i.d.) or once daily (q.d.). A single 300 mg or 600 mg dose of TMC310911 will be administered under fasted or fed conditions. The boosting effect on Darunavir will be investigated.
This is a 96 week study to determine if UK- 453,061 in combination with Truvada is as efficacious, safe and tolerable as efavirenz in combination with Truvada in HIV-1 infected patients who have not been previously treated with antiretroviral drugs.
