Evaluating the Safety and Immunogenicity of the IHV01 Protein Vaccine Primed and Co-Administered With HIV DNA CON-S Env Vaccine in Healthy, HIV-1-Uninfected Adults
a study on HIV/AIDS
The purpose of this study is to evaluate the safety and immunogenicity of the IHV01 protein vaccine primed and co-administered with HIV DNA CON-S env vaccine in healthy, HIV-1-uninfected adults.
A Phase 1b Randomized, Double-blind, Placebo-controlled Clinical Trial to Evaluate the Safety and Immunogenicity of the IHV01 Protein Vaccine Primed and Co-administered With HIV DNA CON-S Env Vaccine in Healthy, HIV-1-Uninfected Adult Participants
This study will evaluate the safety and immunogenicity of the IHV01 protein vaccine primed and co-administered with HIV DNA CON-S env vaccine in healthy, HIV-1-uninfected adults.
Participants will be randomly assigned to two groups. Participants in Group 1 will receive 4 mg of DNA CON-S env at Months 0 and 1. They will receive 4 mg of DNA CON-S env and 150 mcg of IHV01 at Months 3 and 6. Participants in Group 2 will receive placebo at Months 0, 1, 3, and 6.
Study visits will occur at Day 0 (study entry), Week 2, and Months 1, 1.5, 3, 3.5, 6, 6 + 1 week, 6.5, and 12. Visits may include physical examinations, medical history, injection of study product, blood and urine collection, pregnancy testing, HIV testing, risk reduction counseling, and questionnaires.

- Or be sexually abstinent.
- Volunteers who were born female must also agree not to seek pregnancy through alternative methods, such as artificial insemination or in vitro fertilization until after the last required protocol clinic visit
