Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing SARS-CoV-2 Bivalent mRNA vaccine (LVRNA021) and 0.9% sodium chloride solution in people with SARS-CoV-2, run by AIM Vaccine Co., Ltd. at 1 site in Pakistan.

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: status not confirmed, as of the sponsor's last update on 19 Apr 2023. 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 Pakistan. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Xinhui Chen (021-3336 ext. 0772, xinhui.chen@aimbio.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Person-year incidence density of first episodes of virologically-confirmed symptomatic cases of COVID-19 (time frame: 14 days after vaccination or placebo). 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 19 Apr 2023; AzTrials last refreshed its copy on 8 Nov 2026.
