About this study

Official title: Immunogenicity, Reactogenicity and Safety Assessment of the Meningococcal Serogroup C Vaccine Produced by Bio-Manguinhos / FIOCRUZ in Infants, Children and Adolescents

TYPE / DESIGN STUDY: Clinical trial phase II / III, randomized, double-blind, national multi-center, with a total of 1,644 research participants stratified into 3 groups according to age for starting of the primary vaccination schedule (Stratum I - 11 to 19 years, Stratum II - 1 to 10 years; Stratum III - less than 1 year old).

BACKGROUND / STUDY CASE: Clinical trial phase II / III, which purpose is to evaluate immunogenicity, safety and reactogenicity of the vaccine against meningococcus C, conjugated to tetanus toxoid, developed by Bio-Manguinhos / FIOCRUZ (MenCC-Bio). The hypothesis of the study is that MenCC-BIO vaccine is safe and not inferior in terms of immunogenicity to the comparator vaccine currently available for the National Immunization Program in the child's immunization schedule. Thus, MenCC-Bio vaccine may meet the need for expansion of the target age group of vaccination in routine public health services and will be available to the National Immunization Program as a strategy to ensure sustainability and self-sufficiency to vaccination policy.

OBJECTIVES PRIMARY: To assess the immunogenicity of MenCC Bio-vaccine in patients from 3 months to 19 years of age, in relation to the vaccine against meningococcus C currently provided by the National Immunization Program. To evaluate the safety and reactogenicity of MenCC Bio-vaccine in patients from 3 months to 19 years old.

SECONDARY OBJECTIVES: Evaluate the cellular immune component to meningococcal C conjugate vaccine in a subset of survey participants, aged 11 to 19 years.

STUDY POPULATION: Individuals of both sexes, healthy, aged between 3 months and 19 years, attending the campus of Fiocruz / Rio de Janeiro, or municipal health units in Rio de Janeiro (living in areas covered by the municipal units health participants) that fit in the study eligibility criteria.

NUMBER OF CENTRES: Two Clinical sites.

STUDY DURATION: Estimate of 19 months.

INTERVENTION / TREATMENT: Two intervention groups (MenCC-BIO Vaccine and Comparator) in three age groups, with specific vaccination schedules. For the age groups I and II are applied 2 doses ideal interval of 6 months between them. In stratum III, are recommended 3 doses of the vaccine, at ages 3, 5 and 12 months of age, according to calendar of the National Immunization Program.

OUTCOMES PRIMARY:

Immunogenicity:

Proportion of seroconversion defined by the seronegative status change (titles of bactericidal antibodies in children rabbit complement than 1: 8) to seropositive (titers of bactericidal antibodies in larger rabbit complement or equal to 1: 8) or increase 4 times of post vaccinal compared to pre-vacianais after the full vaccination schedule by age stratum.

Geometric mean antibody titers (TGM) pre- and post-vaccination, for each vaccine group, and the ratio of these securities after the full vaccination schedule by age stratum.

Safety and reactogenicity: Frequency and intensity of adverse events solicited and unsolicited, which occurred 30 days after vaccination.

SECONDARY OUTCOME : cell detection B (CD19 +) memory phenotype (CD27 + IgD +, CD27 + IgD) in a subgroup of patients in the age stratum I (11-19 years old). ADDITIONAL INFORMATION age escalation, with interim analysis of inter-layer security and approval by the Security Independent Monitoring Committee of progression to the next lower age stratum.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MenCC-BIO VaccineBiological

    The Bio-MenCC vaccine is composed of serogroup C meningococcal polysaccharide conjugated to tetanus toxoid as the carrier protein, with 10 microgram of capsular polysaccharide of group C, 10-20 microgram of tetanus toxoid per dose and aluminum hydroxide at a concentration of 1 milligram dose (0.35 milligram Al3 +) with phosphate buffered saline as diluent. The vaccine is lyophilized and must be reconstituted with diluent and homogenized at the time of application. The lyophilised vaccine is presented as a white powder and the sterile diluent is translucent. Both are presented in vial of colorless neutral glass.

  • Combined - CRM197Biological

    The comparison is against meningococcal C vaccine produced by the Foundation Ezequiel Dias (FUNED), licensed by ANVISA and currently provided by the National Immunization Program in the child's immunization schedule. This vaccine containing 10 microgram of meningococcal C oligosaccharide conjugate 12,5-25microgram of CRM197 protein of Corynebacterium diphtheriae, and presents aluminum hydroxide (0.3 to 0.4 milligram Al3 +) in its formulation. It is also a lyophilized product must be reconstituted and homogenized before use. The meningococcal C vaccine adsorbed (combined - CRM197) comprises two frascos- ampoule, containing a white or off-white lyophilized powder and another vial containing a white opalescent suspension (diluent).

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing MenCC-BIO Vaccine and Combined - CRM197 in people with Serogroup C Meningococcal Meningitis, run by The Immunobiological Technology Institute (Bio-Manguinhos) / Oswaldo Cruz Foundation (Fiocruz) at 1 site in Brazil.

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 7 inclusion and 23 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: status not confirmed, as of the sponsor's last update on 10 Oct 2018. 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 Brazil. 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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Maria LB Santos (+552138827062, maria.santos@bio.fiocruz.br), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Measure seroconversion proportion (time frame: Immediately before administration of the booster dose). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 10 Oct 2018.
