Rabies vaccine batch check: will it pass the test?

NCT ID NCT07416110

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether three different batches of a rabies vaccine work the same way and are safe. It involves 912 healthy adults aged 18 to 45. The goal is to make sure every batch produces a strong immune response.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
rabies vaccine (Vero cell, freeze-dried)
What this could lead to
If successful, this could confirm that the vaccine is consistently effective and safe, supporting its wider use to prevent rabies after exposure.
What could go wrong
This trial only checks consistency between batches, not whether the vaccine prevents rabies itself. It is also in healthy volunteers, so results may not apply to people with weakened immune systems.
Why investors are watching

Sinovac Biotech is running a Phase IIIb trial with 912 healthy adults aged 18 to 45 to check that three consecutive production batches of its rabies vaccine produce a consistent immune response. For a small-cap company, this readout matters because it tests whether the vaccine can be made reliably at commercial scale, a step needed for regulatory approval and broader market use.

If it works: A positive result could support Sinovac's application to sell the rabies vaccine more widely, potentially adding a steady revenue source from a vaccine with global demand. It could also strengthen the company's reputation for manufacturing quality.

If it fails: If the trial fails to show consistency between batches, or if safety problems appear, regulators may delay or reject the vaccine, and Sinovac would need to fix its manufacturing process. Clinical trials often fail, so investors should expect that outcome as a real possibility.

Inclusion Criteria: 1. Participants are able to understand and voluntarily sign the Informed Consent Form; 2. Able to provide legal identity documents; 3. Age 18 to 45 years; 4. Stable health status (defined as stable underlying disease status within 3 months prior to enrollment, i.e., no change in original treatment or hospitalization due to disorder aggravation); 5. Female participants of childbearing potential must voluntarily adopt effective contraception measures from the signing of the Informed Consent Form until 2 months after the last dose of the investigational Vaccine in the primary immunization series, and have no plans to donate eggs; male participants have no plans to donate sperm; female participants of childbearing potential must also have adopted effective contraception measures within 2 weeks prior to Enrollment. Exclusion Criteria: 1. For subjects with pyrexia on the scheduled vaccination day, axillary temperature \>37.3℃ before vaccination; 2. Previous use of anti-Rabies Passive immunization preparations (including but not limited to equine-derived Immunoglobulin ERIG, human-derived Immunoglobulins HRIG, and rabies monoclonal antibody preparations, etc.) or previous Vaccination with human Rabies Vaccine; 3. Individuals with mammalian animal bites/scratches (e.g., dog/cat) and broken skin (i.e., Category II or higher exposure) within the past year.; 4. Female participants who are lactating or pregnant (including those with a positive urine pregnancy test). 5. Known allergy to any component of the trial Vaccine, or a history of severe allergies (such as anaphylactic shock, allergic laryngeal edema, allergic purpura, severe urticarial rash, dyspnea, angioneurotic edema, etc.); 6. Presence of autoimmune diseases, immunodeficiency diseases (including but not limited to systemic lupus erythematosus, ankylosing spondylitis, asplenia, functional asplenia, splenectomy); 7.
