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.

Ages Eligible for Study

14 years to 36 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Inclusion Criteria:

  1. Compliant with protocol procedures and available for clinical F/U until the protocol-defined end of the trial
  2. Physical examination and laboratory results without clinically significant findings
  3. Body Mass Index (BMI) ≥ 18.0 and ≤ 32.0 kg/m2
  4. Subjects must use reliable forms of contraception (barrier method with spermicidal agent or true abstinence) and must refrain from sperm donation during treatment and the 4-week F/U period after the last treatment.

Exclusion Criteria:

  1. Use of any investigational or non-registered product (adjuvant, drug) other than CV8102 within 4 weeks preceding the administration of the CV8102, or planned use of any such agent during the trial period
  2. Subject has received any licensed or non-licensed vaccines within 4 weeks prior to the administration of CV8102 alone or in combination with the licensed rabies vaccine or planned vaccinations during the trial period
  3. Any treatment with immunosuppressants or other immune-modifying drugs within 6 months prior to the administration of CV8102 alone or in combination with the licensed rabies vaccine. The use of inhaled and nasal steroids, as well as topical steroids outside the vaccination area, will be permitted
  4. Any medically diagnosed or suspected immune deficient condition based on medical history and physical examination
  5. History of autoimmune disease or suspected autoimmune disease based on medical history and physical examination that cannot be ruled out based on further examinations
  6. Administration of immunoglobulins (Igs) and/or any blood products within the 3 months preceding the administration of CV8102 or licensed rabies vaccine
  7. Acute disease at the time of enrolment. Acute disease is defined as the presence of any acute condition including but not limited to non-febrile or febrile common colds, urinary tract infections, inflammatory, allergic or traumatic conditions that may interfere with safety assessment of the investigational products
  8. Presence or evidence of significant acute or chronic disease, in particular heart disease including coronary artery disease and chronic pulmonary diseases (e.g., chronic obstructive pulmonary disease [COPD]); uncontrolled medical or psychiatric illness (subjects with uncomplicated chronic diagnoses stable and treated for ≥ 3 months e.g., mild hypertension well-controlled with medication, may be enrolled - provided the condition and its therapy are known not to be associated with an immunocompromised state or an autoimmune disease)
  9. Major congenital defects
  10. Known allergy to any component (or closely related substance) of the licensed rabies vaccine product
  11. Known type I allergy to beta-lactam antibiotics
  12. Evidence of current alcohol or drug abuse
  13. History of any neurological disorders or seizures
  14. Known seropositivity for human immunodeficiency virus (HIV), hepatitis B virus (HBV) (except in subjects previously vaccinated against HBV) or hepatitis C virus (HCV)
  15. Foreseeable non-compliance with protocol as judged by the Investigator
  16. History of any life-threatening anaphylactic reactions

  17. Subjects with impaired coagulation in whom an IM injection is contraindicated.

    Additional exclusion criteria for subjects participating in the (adjuvanted) rabies vaccination part:

  18. Subject has previously received any investigational or licensed rabies vaccine
  19. Intending to travel to regions/countries for which rabies vaccinations are recommended or where high risk of infection exists according to travel recommendations by the German Society of Tropical Medicine and International Health (DTG) during the trial and F/U period
  20. Subject is taking chloroquine for malaria treatment or prophylaxis.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures
