Immunogenicity and Safety of Verorab™ in Indian Population

January 10, 2014 updated by: Sanofi Pasteur, a Sanofi Company

Immunogenicity and Safety of Purified Vero Cell Rabies Vaccine (PVRV, Verorab™) Administered for Rabies Post-exposure Treatment. Comparison of Essen-IM, Zagreb-IM, and Thai Red Cross (TRC)-ID Regimens in the Indian Population.

  • To demonstrate that rabies vaccine administered according to the Thai Red Cross, (TRC)-ID regimen (2-2-2-0-1-1) is not inferior to rabies vaccine administered according to the ESSEN IM regimen in terms of Geometric Mean Titers (GMTs) at D28, in subjects with a WHO category III rabies exposure,or,
  • To demonstrate that Rabies vaccine administered according to the ZAGREB-IM regimen (2-1-1) is not inferior to Rabies vaccine administered according to the ESSEN IM regimen in terms of GMTs at D28, in subjects with a WHO category III rabies exposure.

Secondary objectives:

  1. To describe the immunogenicity profile of each regimen
  2. To assess the safety of the vaccine in each group.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
