About this study

Official title: Verorab® Immunogenicity and Safety After a One-week, 4-site, Intradermal (ID) Post-exposure Prophylaxis Regimen (4-4-4-0-0) Followed by a One-visit, 4-site, ID Booster at Five Years

The purpose of this study is to assess the 4-site "one-week" post-exposure prophylaxis (PEP) regimen as a possible alternative to the 2-site updated Thai Red Cross (TRC) PEP regimen.

Primary objective:

Read more
  • To demonstrate that PEP using the new "one-week, 4-site" (4-4-4-0-0) intradermal (ID) vaccination regimen is non-inferior to PEP using the updated TRC (2-2-2-0-2) ID vaccination regimen.

Secondary objectives:

  • Primary immunization: To describe the immune response in each group at Day 0, Day 14 and Day 90.
  • Antibody persistence: To describe rabies virus-neutralizing antibody persistence during the 5 years after completion of PEP in each group.
  • Booster vaccination: To describe the immune response induced by a single-visit 4-site intradermal booster vaccination in each group at Year 5.
  • Safety: To describe the safety profile of each group after the primary and booster vaccinations.
Read the detailed description

Participants with WHO Category II exposure will receive PEP, using "one-week, 4-site" ID vaccination regimen. Participants with WHO Category III exposure will receive PEP, using "one-week, 4-site" (4-4-4-0-0) ID vaccination regimen and pERIG Favirab® or using the updated 2-site TRC (2-2-2-0-2) ID vaccination regimen and pERIG Favirab®. All participants will receive a "single-visit, 4-site" booster vaccination five years later.

What is being measured

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

  1. Percentage of participants with seroconversion on Day 14

    Seroconversion is defined as rabies virus neutralizing antibody titers ≥ 0.5 IU/mL

    Measured: Day 14 post vaccination

Secondary outcomes (8)
  1. Percentage of participants with seroconversion before and after primary vaccination

    Seroconversion is defined as rabies virus neutralizing antibody titers ≥ 0.5 IU/mL

    Measured: Day 0, Day 14, Day 90

  2. Percentage of participants with seroconversion after primary vaccination (antibody persistence)

    Seroconversion is defined as rabies virus neutralizing antibody titers ≥ 0.5 IU/mL

    Measured: Year 1 to Year 5

  3. Percentage of participants with seroconversion after booster vaccination

    Seroconversion is defined as rabies virus neutralizing antibody titers ≥ 0.5 IU/mL

    Measured: Year 5 + 11 days

  4. Geometric mean titers (GMTs) before and after primary vaccination

    Titers of rabies virus-neutralizing antibodies were assessed by the rapid fluorescent focus inhibition test

    Measured: Day 0, Day 14, Day 90

  5. GMTs after primary vaccination (antibody persistence)

    Titers of rabies virus-neutralizing antibodies were assessed by the rapid fluorescent focus inhibition test

    Measured: Year 1 to Year 5

  6. GMTs after booster vaccination

    Titers of rabies virus-neutralizing antibodies were assessed by the rapid fluorescent focus inhibition test

    Measured: Year 5 + 11 days

  7. Number of participants reporting solicited injection site reactions following primary and booster vaccination

    Solicited injection site reactions are tenderness (for participants aged ≤ 23 months), pain (for participants aged ≥ 2 years), redness and swelling (for all participants)

    Measured: 7 days after each and any injection

  8. Number of participants reporting solicited systemic reactions following primary and booster vaccination

    Solicited systemic reactions are Fever, Vomiting, Crying abnormal, Drowsiness, Appetite lost, and Irritability for participants aged ≤ 23 months and Fever (Temperature), Headache, Malaise, and Myalgia for participants aged ≥ 2 years

    Measured: From Day 0 up to 7 days after injection 3, and 7 days after subsequent injections

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing PVRV and PVRV and pERIG Favirab® in people with Rabies, run by Sanofi Pasteur, a Sanofi Company at 1 site in Philippines.

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 9 inclusion and 21 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 25 Apr 2022. 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 Philippines. 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 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?

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?

Percentage of participants with seroconversion on Day 14 (time frame: Day 14 post vaccination). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01622062, which also lists 1 linked publication.

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 25 Apr 2022.
