About this study

Official title: Phase 1 Proof-of-Concept Study to Evaluate the Safety and Immunogenicity of a Priming VaccinationRegimen of Uvax Bio's Glycan Trimmed HIV-1 Vaccine (UVAX-1107) With CpG 1018®/Aluminum HydroxideAdjuvant in Healthy Adults (25-55 Years), Followed by Boosting Vaccination Regimen Using UVAX-1107 orWildtype Non-Glycan Trimmed HIV-1 Vaccine (UVAX-1197) With CpG 1018®/Aluminum Hydroxide Adjuvant

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.

Read the 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).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To assess local and systemic reactogenicity following vaccination (Day 1 to Day 8, inclusive) following each vaccination.

    Reactogenicity (local and systemic) will be recorded by the subject using a daily diary after vaccination andfor 6 consecutive days thereafter.

    Measured: Days 1 through Day 7 after each vaccination.

  2. To determine if antibody responses are induced at 2 weeks after each vaccination using anti-HIV-1 protein IgG.

    Serum samples will be collected at specified timepoints for HIV-1-specific IgG titers

    Measured: Pre-vaccination timepoints (Day 1, Day 57, Day 141 and Day 225) and ~2 weeks after each vaccination (Day15, Day 71, Day 155 and Day 239) and Day 337 post enrolment/End of study (EOS).

Secondary outcomes (7)
  1. To assess serious adverse events (SAEs) or adverse events of special interest (AESI) attributed to vaccination.

    As the proposed trial (UVAX-HIV-101) will be the first study of UVAX-1197 and -1107 in humans, there is currently no data regarding AEs associated with either UVAX-1197 or -1107 in humans. UVAX-1197 and -1107 have been administered in animals without significant adverse reactions being observed. Based on preclinical experience and AEs generally observed in other intramuscular administered vaccines using a similar development platform, the vaccinations are expected to result in mild to moderate local reactions and/or systemic reactions. These AEs will be assessed via clinical examination at the reference timepoints and via the use of a subject diary for the 7 days following each vaccination.

    Measured: At all visits, Day 1, Day 8, Day 15, Day 29, Day 57, Day 64, Day 71, Day 85, Day 141, Day 148, Day 156, Day 169,Day 225, Day 232, Day 239, Day 253 and Day 337 post enrolment/End of Study (EOS).

  2. To describe occurrence of Medically Attended Adverse Events (MAAEs).

    MAAEs (e.g. any AEs that are evaluated by a healthcare professional either at the site or within the community) will be reported from Day 1 through 28 days after the last vaccination was received. They will be assessed using study-specific questionnaire, clinical examination and data-linkage to medical records. These AEs will be assessed via clinical examination at the reference timepoints and via the use of a subject diary for the 7 days following each vaccination.

    Measured: On pre- and post-dose Day 1, Day 8, Day 15, Day 29, pre- and post-dose Day 57, Day 64, Day 71, Day 85,pre- and post-dose Day 141, Day 148, Day 156, Day 169, pre- and post-dose Day 225, Day 232, and Day 253

  3. To describe occurrence of treatment emergent adverse events (TEAEs)

    TEAEs (e.g. any AEs that occur after the study product has been administered) will be reported throughout the study period until Day 253 (28 days following the last dose) .They will be assessed, using study-specific questionnaire, clinical examination and data-linkage to medical records. These AEs will be assessed via clinical examination at the reference timepoints and via the use of a subject diary for the 7 days following each vaccination

    Measured: Endpoint will evaluate TEAEs reported until Day 29 following each vaccination (Day 1, Day 8, Day 15, Day 29,post-dose Day 57, Day 64, Day 71, Day 85, post-dose Day 141, Day 148, Day 156, Day 169, post-dose Day225, Day 232, and Day 253).

  4. To describe occurrence of laboratory-related adverse events from pre-vaccination to 7 days following each vaccination.

    Clinically significant abnormal laboratory values for chemistry, hematology and bleeding indices will be graded according to the FDA toxicity scale, or CTCAE if not graded within the FDA scale, and recorded as an AE.

    Measured: Screening visit, Day 8, pre-dose Day 57, Day 64, pre-dose Day 141, day 148, pre-dose Day 225, Day 239 and Day 337 post-enrolment/End of Study (EOS)

  5. To describe occurrence of adverse events from vital sign measurements following each vaccination.

    Vital signs assessments will include oral temperature (degrees C) using an oral/tympanic thermometer, respiratory rate (breaths per minute) using manual assessment of breaths, systolic and diastolic blood pressure (mmHg) and heart rate (bpm) using a digital blood pressure machine. Clinically significant abnormal vital sign measurements will be graded according to the FDA toxicity scale, or CTCAE if not graded within the FDA scale, and recorded as an AE.

    Measured: All study visits (Screening, pre- and post-dose Day 1, Day 8, Day 15, Day 29, pre- and post-dose Day 57, Day64, Day 71, Day 85, pre- and post-dose Day 141, Day 148, Day 156, Day 169, pre- and post-dose Day 225, Day232, Day 253 and Day 337.

  6. To determine difference in autologous neutralizing antibody response across dose groups

    Serum will be collected for assessment of occurrence and level of HIV-1-specifi c neutralization titers against vaccine neutralization titers against select Tier 2 panels

    Measured: Pre-vaccinations timepoints (Day 1, Day 57, Day 141 and Day 225), and ~2 weeks after each vaccination (Day15, Day 71, Day 155, and Day 239) and at the EOS (Day 337 post-enrolment).

  7. To determine difference in heterologous neutralizing antibody response across dose groups

    Serum will be collected for assessment of occurrence and level of HIV-1-specific neutralization titers against select Tier 2 panels

    Measured: Days 155 and 239. Conditional testing at timepoints (Day 1, Day 57, Day 141 and Day 225), and remaining post-vaccination timepoints (Day 15, Day 71) may be performed

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing UVAX-1107 and UVAX-1197 in people with AIDS/HIV - RelatedDisease Associated With AIDS and Vaccine-Preventable Diseases, run by Uvax Bio LLC at 1 site in Australia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To assess local and systemic reactogenicity following vaccination (Day 1 to Day 8, inclusive) following each vaccination. (time frame: Days 1 through Day 7 after each vaccination.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 May 2025.
