Detailed Description
This study will evaluate the safety and immunogenicity of HIV-1 BG505 SOSIP.664 gp140 with TLR agonist and/or alum adjuvants in healthy, HIV-uninfected adults.
The study will be conducted in three parts (Part A, B and C). Part A will include two groups (Groups 1 and 2), Part B will include four groups (Groups 3, 4, 5, and 6) and Part C will include two groups (Groups 7 and 8).
Participants in Part A will be randomly assigned to receive the BG505 SOSIP.664 gp140 vaccine admixed with 3M-052-AF and alum adjuvant or to receive placebo. Part A participants will be enrolled sequentially in Groups 1 and 2 for dose escalation.
Participants in Part B will be randomly assigned to Groups 3, 4, 5, or 6, to receive the BG505 SOSIP.664 gp140 vaccine with an adjuvant (the specific adjuvant will vary by group) or to receive placebo.
Participants in Part C will be randomly assigned to Groups 7 or 8 to receive the Trimer 4571 (BG505 SOSIP.664 DS gp140) with 3M-052-AF + Alum or to receive placebo.
Participants in Part A will attend 8 months of scheduled clinic visits, and they will be contacted by study staff at Month 14 for follow-up health monitoring. Participants in Part B will attend 18 months of scheduled clinic visits. Participants in Part C will attend 18 months of scheduled clinic visits.

Exceptions may be made by the HVTN 137 PSRT for vaccines that have subsequently undergone licensure by the FDA. For volunteers who have received control/placebo in an experimental vaccine trial, the HVTN 137 PSRT will determine eligibility on a case-by-case basis. For volunteers who have received an experimental vaccine(s) greater than 1 year ago, eligibility for enrollment will be determined by the HVTN 137 PSRT on a case-by-case basis.

- Any contraindication to repeated injections or blood draws,
- A condition that requires active medical intervention or monitoring to avert grave danger to the volunteer's health or well-being during the study period,
- A condition or process for which signs or symptoms could be confused with reactions to vaccine, or
- Any condition specifically listed among the exclusion criteria below.
