HIV Infections Clinical Trial
Official title:
A Phase I, Dose Escalation, Safety, and Immunogenicity Trial of an Alphavirus Replicon HIV-1 Subtype C Gag Vaccine (AVX101) in Healthy HIV-1 Uninfected Adult Participants
The purpose of this study is to evaluate the safety of and immune response to an alphavirus replicon, HIV-1 subtype C gag vaccine, AVX101, in HIV uninfected adults in the United States, South Africa, and Botswana.
HIV-1 subtype C is the prevailing subtype of HIV found in sub-Saharan Africa and is
primarily responsible for the HIV/AIDS epidemic in southern Africa. Thus, development of a
preventive subtype C vaccine is critically important in controlling the spread of HIV in
this part of the world. This study will determine the safety and immunogenicity of an
alphavirus replicon HIV-1 subtype C gag vaccine, AVX101, in HIV uninfected adults. This
vaccine utilizes a propagation-defective replicon vector system derived from an attenuated
strain of Venezuelan Equine Encephalitis (VEE) virus. The vaccine replicon expresses the gag
gene from a South African subtype C isolate of HIV-1. Participants will be recruited in the
United States, South Africa, and Botswana.
The study will last for 1 year. Participants will be enrolled sequentially, from lowest to
highest dose of vaccine, into one of four groups. Groups will begin enrollment only
following safety review of the previous group. Participants will be randomly assigned to
receive active vaccine or placebo. During the study, participants will receive either 3
injections of one of four possible doses of the vaccine or 3 injections of placebo.
Injections will be given at study entry and at Days 28 and 84. At screening, participants
will undergo medical history assessment, a complete physical, HIV testing and counseling,
and blood and urine collection; they will also be interviewed and asked to complete a
questionnaire. After screening, there will be 8 study visits; the visits will occur at Days
14, 28, 42, 84, 98, 168, 273, and 364. Participants will be interviewed and asked to fill
out a questionnaire at each study visit; participants will undergo a physical, additional
HIV testing and counseling, and blood and urine collection at selected visits.
