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.

Detailed Description

Open label study to assess the safety and immunogenicity of MVA-mBN85B in healthy vaccine-naive, measles-naive and measles-experienced children. The study is comprised of three groups with 30 children each. Two groups will receive two subcutaneous (s.c.) immunizations 4 weeks (28±3 days) apart of either either 1 x 10E7 TCID50 (Group A) or 1 x 10E8 TCID50 (Group B) MVA mBN85B. The control group (Group C) will receive two s.c. doses (0.5 ml, 1000 TCID50) of Rouvax® (Sanofi-Pasteur) 24 weeks apart.

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

6 months to 6 years (Child)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Read, signed and dated informed consent document from one parent/guardian of the child after being advised of the risks and benefits of the study in a language understood by the parent/guardian. This document must be signed prior to performance of any study specific procedure.
  2. Male or female child between the age of 6 months to 6 years (Group C: 9 months to 6 years).
  3. Prior or no prior measles vaccination indicated on the RTHC.
  4. No known exposure to measles within 30 days prior to study entry.
  5. No history of measles disease.
  6. Negative human immunodeficiency virus antibody test (anti-HIV) and hepatitis B surface antigen (HBsAG).
  7. Child is in good health as determined by medical history, physical examination and clinical judgment.
  8. Children for whom the investigator reasonably believes its parents/guardian can and will comply with the requirements of the protocol

Exclusion Criteria:

  1. Any clinically significant condition that may influence participation in this study, including febrile convulsions.
  2. Severe malnutrition as assessed by the investigator by weight for age and clinical criteria.
  3. History of splenectomy.
  4. Clinically significant anaemia (laboratory and clinical criteria).
  5. Having received any vaccinations or planned vaccinations with a live vaccine within 30 days prior to or after study vaccination.
  6. Having received any vaccinations or planned vaccinations with a killed vaccine within 14 days prior to or after study vaccination.
  7. Administration or planned administration of immunoglobulins and/or any blood products during a period starting from 3 months prior to administration of the vaccine and ending at study conclusion.
  8. Use of any investigational or non-registered drug or vaccine other than the study vaccine within 30 days preceding the first dose of the study vaccine, or planned administration of such a drug during the study period.
  9. History of any serious medical condition, which in the opinion of the investigator, would compromise the safety of the child.
  10. History of or currently active autoimmune disease. Children with vitiligo or thyroid disease on thyroid replacement therapy are not excluded.
  11. History of malignancy, especially leukaemia or lymphoma.
  12. History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
  13. History of anaphylaxis or severe allergic reaction.
  14. Known allergy to egg proteins, gelatine, neomycin or gentamycin.
  15. Chronic administration (defined as more than 14 days) of systemic high dose immuno-suppressant drugs during a period starting from six months prior to administration of the vaccine and ending at study conclusion. High dose is defined as 2 mg/kg/day or more of prednisolone or its equivalent, or 20 mg/day or more for children who weigh more than 10 kg.
  16. Previous participation in an MVA-based vaccination study

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

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.
