Brief Summary:
This is a first in human testing of novel HIV-1 protein nanoparticles vaccine candidates, UVAX-1107 and UVAX-1197 mixed with Aluminum Hydroxide (AH) and CpG 1018 adjuvants. After meeting all eligibility criteria, approximately 34 participants will receive a 4-dose vaccination regimen of either 2 priming vaccinations of UVAX-1107 followed by 2 boosting vaccinations of UVAX-1197, or 4 doses of UVAX-1107, or placebo. Subject participation is expected to last up to 374 days, including up to a 30-day screening period and a 337-day study period during which subjects will be followed for safety and immunogenicity outcomes.
Detailed Description:
This is a first in human testing of a novel HIV-1 vaccine candidate. Both UVAX-1197 and UVAX-1107 are protein nanoparticle vaccines displaying an uncleaved, prefusion-optimized (UFO) envelope (Env) glycoprotein from HIV-1 BG505 (BG505-UFO). The UVAX-1197 displays fully glycosylated UFO Env trimers with wildtype glycans (WT). UVAX-1107 is derived from UVAX-1197 by enzymatic "glycan trimming" (GT) of N-linked glycans in order to better expose major neutralizing epitopes on the surface of BG505-UFO Env to immune recognition. The optimized vaccine immunogens will be mixed with Aluminum Hydroxide (AH) and CpG 1018 adjuvants to enhance the immune response. Subject participation is expected to last up to 374 days, including up to a 30-day screening period and a 337-day study period.
Part 1 of the study will be a safety lead-in cohort in which 4 participants will receive 2 priming vaccinations of a half dose of adjuvanted UVAX-1107 (administered in 0.5ml intramuscular injection) on Days 1 and 57 followed by boosting vaccinations of a half dose of adjuvanted UVAX-1197 on Days 141 and 225, administered as intra-muscular (IM) injections. Safety will be reviewed after subjects in Part 1 reach Day 8, prior to opening Part 2.
A separate group of participants will be enrolled in Part 2 of the study. Participants in Part 2 will be randomized to the following treatment arms to receive either:
* Priming vaccinations of adjuvanted UVAX-1107 (full dose, administered in 0.5ml intramuscular injection) on Days 1 and 57 followed by boosting vaccinations of adjuvanted UVAX-1197 (full dose, administered in 0.5ml intramuscular injection) on Days 141 and 225.
* Priming vaccinations of adjuvanted UVAX-1107 (full dose) on Days 1 and 57 followed by boosting vaccinations of adjuvated UVAX-1107 (full dose) on Days 141 and 225.
When Part 2 of the study opens, 5 sentinel participants (2 from each of the active treatment groups and 1 from the placebo group) will be randomized. Safety will be reviewed after these first 5 Part 2 participants reach Day 8 prior to opening randomization to the remaining participants in Part 2.
Vaccinations will be administered by trained staff at the study site(s) according to site's SOPs. Details regarding dosing, including the dose administered, arm, and the date and time of dosing, will be recorded in the subjects source notes and electronic case report form (eCRF).
