About this trial

This is an interventional prevention trial for Rabies focused on measuring Rabies, Purified Vero Rabies Vaccine - Serum Free, Human Diploid Cell Vaccine, Imovax® Rabies

Eligibility Criteria

18 Years - 64 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • Aged 18 to < 65 years on the day of inclusion
  • Informed consent form has been signed and dated - Able to attend all scheduled visits and comply with all trial procedures.

Exclusion Criteria:

  • Subject is pregnant, or lactating, or of childbearing potential (to be considered of non-childbearing potential, a female must be post-menopausal for at least 1 year, surgically sterile, or using an effective method of contraception or abstinence from at least 4 weeks prior to the first vaccination and until at least 4 weeks after the last vaccination)
  • Participation at the time of study enrollment or planned participation during the present trial period in another clinical trial investigating a vaccine, drug, medical device, or medical procedure
  • Receipt of any vaccine in the 4 weeks preceding the first trial vaccination or planned receipt of any vaccine during the course of the trial
  • Previous vaccination against rabies (in pre- or post-exposure regimen) with either the trial vaccine or another vaccine
  • Receipt of immunoglobulins, blood or blood-derived products in the past 3 months
  • Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy, within the preceding 6 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months)
  • Self-reported seropositivity for Human Immunodeficiency Virus (HIV), Hepatitis B, or Hepatitis C
  • At high risk of rabies infection during the trial
  • Known systemic hypersensitivity to any of the components of either vaccine or HRIG, or history of a life-threatening reaction to the vaccines used in the trial or to a vaccine containing any of the same substances
  • Self-reported thrombocytopenia, contraindicating intramuscular (IM) vaccination
  • Bleeding disorder, or receipt of anticoagulants in the 3 weeks preceding inclusion, contraindicating IM vaccination
  • Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily
  • Current alcohol abuse or drug addiction
  • Chronic illness that, in the opinion of the Investigator, is at a stage where it might interfere with trial conduct or completion
  • Moderate or severe acute illness/infection (according to investigator judgment) on the day of vaccination or febrile illness (temperature ≥ 100.4°F). A prospective subject should not be included in the study until the condition has resolved or the febrile event has subsided
  • Identified as an Investigator or employee of the Investigator or study center with direct involvement in the proposed study, or identified as an immediate family member (i.e., parent, spouse, natural or adopted child) of the Investigator or employee with direct involvement in the proposed study
  • History of Guillain-Barré Syndrome.

5. Study Description

Brief Summary
The aim of the study is to document the safety and immunogenicity of Purified Vero Rabies Vaccine (VRVg) when given in a simulated post-exposure regimen, i.e. with co-administration of human rabies immunoglobulins (Imovax® Rabies). Primary Objectives: To demonstrate that VRVg is non-inferior to Imovax® Rabies in terms of proportion of subjects achieving a rabies virus neutralizing antibody (RVNA) titer ≥ 0.5 international units (IU)/mL at Day 14. To demonstrate that the observed proportion of subjects achieving an RVNA titer ≥ 0.5 IU/mL at Day 14 is at least 99%, with a lower limit of the 95% confidence interval (CI) of at least 97%. Secondary Objectives: To assess the clinical safety of each vaccine after each vaccine injection when administered in a simulated post-exposure schedule. To describe the geometric mean titer ratio (GMTR) between the 2 vaccine groups at Day 14.
Detailed Description
All participants will receive five vaccine injections, i.e. one at Day 0, at Day 3, at Day 7, at Day 14 and at Day 28, respectively, (Essen regimen). In addition, human rabies immunoglobulins (HRIG) will be concomitantly administered to all subjects on Day 0. Safety will be assessed in all participants up to 28 days after vaccination, as applicable, in terms of occurrence of adverse events (AEs), and serious adverse events (SAEs) and adverse events of special interest (AESIs) up to 6 months post-vaccination 5.
