What is being measured

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

  1. SAD: Number of Participants with Adverse Events (AEs) as per Severity

    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. Severity of Adverse Event will be assessed using Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events (DAIDS). DAIDS grading scale is used to grade the toxicity associated with injection site reactions (ISR) including injection site pain (or tenderness), erythema (or redness), induration (or swelling), and pruritis. The toxicity level is graded from grade 1(lowest toxicity) to 4 (highest toxicity). Higher grade indicates higher toxicity.

    Measured: Up to Week 52

  2. MAD: Number of Participants with Adverse Events (AEs) as per Severity

    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. Severity of Adverse Event will be assessed using Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events (DAIDS). DAIDS grading scale is used to grade the toxicity associated with injection site reactions (ISR) including injection site pain (or tenderness), erythema (or redness), induration (or swelling), and pruritis. The toxicity level is graded from grade 1(lowest toxicity) to 4 (highest toxicity). Higher grade indicates higher toxicity.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing VH4004280 and VH4011499 in people with HIV Infections, run by ViiV Healthcare at 2 sites in United States.

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 4 inclusion and 20 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 5 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

SAD: Number of Participants with Adverse Events (AEs) as per Severity (time frame: Up to Week 52). The study lists 24 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 5 Aug 2026.
