A Clinical Trial to Evaluate the Safety and Immunogenicity of Glycan-trimmed HIV-1 Nanoparticle Vaccine (UVAX-1107), Followed by Homologous or Wild-type HIV-1 Nanoparticle Vaccine (UVAX-1197) Boost, Each Adjuvanted With 3M-052-AF + Alum in Adult Participants Without HIV

This is a phase 1, first-in-human (FIH) trial for the combination of UVAX-1107 and UVAX-1197, both adjuvanted with 3M-052-AF + Aluminum Hydroxide Suspension (Alum). This means it is the first time this combination of study products is being tested in people.

The purpose of this study is to see if the study products are safe, if people are able to take them without becoming too uncomfortable, and how a person's immune system responds to them (a person's immune system protects them from infections and disease).

Twenty-five volunteers without HIV and in overall good health will be enrolled and be in this study for a little over 1 year (56 weeks) of clinic visits (about 12 visits), with a follow-up contact 1 year after the final injection to check on their health.

Study procedures will include blood draws, injections, and the collection of white blood cells and cells from their lymph nodes.


Eligibility Criteria:
Inclusion Criteria:

* Understand the study and agree to participate.
* Be available for follow-up visits and contact for 12 months after the last study product is administered.
* Be willing to undergo all study procedures.
* Not be in another study unless approved by both study sponsors.
* Be in good general health.
* Have normal physical exam and lab results.
* Agree to discuss HIV risk and prevention.
* Have a certain minimum hemoglobin level (≥ 11.0 g/dL for women, ≥ 13.0 g/dL for men).
* Have a white blood cell count within 2500 to 12,000/mm³.
* Have a platelet count between 125,000 to 550,000/mm³.
* Have an ALT level less than 2.5 times the upper limit of normal.
* Have a serum creatinine level within 1.1 times the normal limit.
* Have a serum calcium level of at least 8.5 mg/dL.
* Have blood pressure within specified limits.
* Test negative for HIV.
* Test negative for Hepatitis C.
* Test negative for Hepatitis B.
* Women who can become pregnant must use effective contraception and test negative for pregnancy at enrollment.
* Women who can become pregnant must agree not to seek pregnancy through alternative methods during the study period.

* Have an immune deficiency or are taking medications that impair immune response.
* Received blood products or immunoglobulins within the last 16 weeks.
* Received certain vaccines within 4 weeks before enrollment.
* Received other vaccines within 14 days before enrollment.
