Filter by:This study is being conducted to look at how the body handles the drugs darunavir and etravirine. It will measure the amount of darunavir and etravirine in blood, semen, and in the rectum of men. The aim is to understand how much of the drug (taken by mouth) reaches the reproductive and intestinal tracts. It is believed that the presence of this drug in these areas may be beneficial in preventing the AIDS virus (HIV) from being passed from one person to another. The study will take samples of blood, semen and rectal mucosal tissue to measure drug levels. This study will also collect information on side effects.
The HIV integrase inhibitor, raltegravir (RAL), which was recently approved by the FDA, has been shown in several trials to be highly effective. The main study will estimate the viral load decay rate in treatment-naive HIV-infected participants receiving RAL and emtricitabine/tenofovir disoproxil fumarate (FTC/TDF). This substudy of A5248 will similarly examine the characteristics of decrease in viral load but will focus on estimating the time at which first-phase viral decay starts, following initiation of the study drugs.
Herpes zoster, or shingles, is the result of a viral infection that causes a painful skin rash, usually in older people or people with suppressed immune systems like those infected with HIV. The ZOSTAVAX vaccine has been shown to reduce the number of infections and symptoms of herpes zoster infection in people over the age of 60. The purpose of this study is to evaluate the safety, tolerability, and immunogenicity of two doses of ZOSTAVAX in HIV-1-infected adults with conserved immune function (Cd4+ T cell counts >=200 cells/uL) virologically suppressed on potent combination antiretroviral therapy (ART).
The purpose of this study is twofold: (1) to assess the feasibility and safety of fixed dose combination zidovudine/lamivudine/abacavir in HIV infected subjects with tuberculosis in a resource-limited setting, and (2) to assess the impact of delayed versus early initiation strategies for fixed dose combination zidovudine/lamivudine/abacavir on the rate of tuberculosis-associated immune reconstitution inflammatory syndromes.
The design of this randomized controlled trial (RCT) is to test the effectiveness of a post-test behavioral video in educating adolescents about HIV transmission and affecting their intentions to engage in risk-reduction behavior.
The purpose of this study is to evaluate the safety and immunogenicity of Ad35-GRIN/ENV HIV vaccine and Ad35-GRIN HIV vaccine administered intramuscularly at 0 and 6 months.
Topical microbicides, substances that kill microbes, are being studied to prevent sexual transmission of HIV and other disease pathogens. In the future, topical microbicides may be applied vaginally to prevent both acquisition and transmission of HIV and other sexually transmitted infections (STIs). The purpose of this study is to compare the safety of daily applications of Acidform lubricant and HEC gel in healthy women at low risk for HIV infection and assess the effect of a microbicide candidate on the natural immunity women have to STI pathogens.
A study to assess the general safety and tolerability of the administration of the 3-dose regimen of the MRKAd5+6 trigene vaccine
The purpose of this study is to test if sexual health interventions can reduce the incidence of STIs among African American teens (15 to 21 years old). By doing this study, we hope to help African American teens improve their condom use skills and encourage them to use condoms more frequently. If the number of STIs in this population can be decreased, the health of African American teen males will greatly improve. We also believe that sexual partners (typically African American teen females) will also benefit.
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.
