HIV Infections Clinical Trial
Official title:
A Phase I Dose-Ranging Study of the Safety, Tolerability, and Immunogenicity of the Merck Trivalent Adenovirus Serotype 5 HIV-1 Gag/Pol/Nef Vaccine (MRKAd5 HIV-1 Gag/Pol/Nef) in a Prime-Boost Regimen in Healthy Adults
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 study will proceed in four stages. Following stages I, II and III, all subjects will
have the Postdose 1 (PD1) clinical and laboratory safety data reviewed by the Safety
Evaluation Committee (SEC). If these data are acceptable, the next stage will be initiated.
- In Stage I, participants will be randomized to receive 3 doses of the 3x10^9vp/dose
level Trivalent vaccine or placebo.
- In Stage II, participants will be randomized to receive 2 or 3 doses of the
3x10^10vp/dose level Trivalent vaccine or placebo.
- In Stage III, participants will be randomized to receive 3 doses of the Trivalent
vaccine with titers of 1x10^11vp/dose, 3x10^6vp/dose, 3x10^7vp/dose, or 3x10^8vp/dose
or placebo.
- In Stage IV, participants will be randomized to all treatment groups. In addition, some
participants will be randomized to an MRKAd 5 HIV-1 gag Monovalent vaccine. In this
stage, participants will be pre-stratified by baseline Ad5 titers (=<200, and >200), to
ensure an even distribution of participants with high and low Ad5 titers across the
various treatment groups.
