What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • hAd5-S-Fusion+N-ETSD vaccineBiological

    The hAd5-S-Fusion+N-ETSD vaccine is a hAd5 [E1-, E2b-, E3-] vector-based targeting vaccine encoding the SARS-CoV-2 S and N proteins. The hAd5-S-Fusion+N-ETSD vaccine is designed to induce both humoral and cellular responses even in individuals with pre-existing adenoviral immunity.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing hAd5-S-Fusion+N-ETSD vaccine in people with Covid19, run by ImmunityBio, Inc. at 1 site in South Africa.

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 21 inclusion and 29 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 15 Nov 2024. 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 South Africa. 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. 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?

Yes. Results are posted in the registry (first posted 15 Nov 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With Medically Attended Adverse Events (MAAE) (time frame: From first dose of study treatment through 1 week post final vaccine administration; up to 29 days for Cohorts 1 and 2, and up to 8 days for Cohorts 3 and 6.). The study lists 8 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 15 Nov 2024.
