NCT01482052

Brief Summary

The purpose of this study is to evaluate the safety of a new conjugate vaccine, NmVac4-A/C/Y/W-135-DT, compared to the safety of a similar, licensed meningococcal A/C/Y/W-135-DT conjugate vaccine. The investigators will also evaluate the production of antibodies to of NmVac4-A/C/Y/W-135-DT™ conjugate vaccine compared to the licensed vaccine, as a measure of vaccine effectiveness.

Outcome Measures

Primary Outcomes (1)

  • Adverse Reactions

    local and systemic rates throughout the course of the study

    up to 6 months

Secondary Outcomes (1)

  • Immune Response

    4 and 8 weeks after injection

Study Arms (2)

Test Vaccine

EXPERIMENTAL

NmVac4-A/C/Y/W-135-DT™ conjugate vaccine

Biological: meningococcal meningitis conjugate vaccine, quadrivalent

US Licensed Vaccine

ACTIVE COMPARATOR

Meningococcal (Groups A, C, Y and W-135) Polysaccharide Diphtheria Toxoid Conjugate Vaccine

Biological: meningococcal meningitis conjugate vaccine, quadrivalent

Interventions

NmVac4-A/C/Y/W-135-DT™conjugate is a vaccine in liquid form composed of purified polysaccharides (PS) conjugated to diphtheria toxoid. Single intramuscular 0.5 mL dose contains 4 µg each Serogroup A, C, W-135, Y PS conjugated to approximately 16 µg total diphtheria toxoid.

Also known as: NmVac4-A/C/Y/W-135-DT™

Eligibility Criteria

Age18 Years - 50 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Willing and able to give informed consent and comply with all aspects of the evaluation after the nature of the study is explain
  • For the purpose of this study, a healthy volunteer is defined as healthy male or female, with no significant chronic conditions
  • Age 18 to 50 years old
  • Either gender. Abstinence or use of contraception during the eight weeks after vaccination will be required for non menopausal (\< two years post-menopause) or non surgically sterile women
  • Persons with antibody titer(s) of \<2 µg/mL to serogroup(s) A, C, Y, or W-135 polysaccharides as measured by ELISA

You may not qualify if:

  • Age less than 18 years or over 50 years.
  • History of Guillain-Barré syndrome (GBS).
  • Pregnancy or lactation.
  • History of meningococcal meningitis.
  • History of invasive (clinical or laboratory diagnosis) meningococcal disease.
  • History of meningococcal meningitis vaccination.
  • Screening laboratory abnormalities (in the opinion of the Investigator) that would raise safety concerns for participation in the study.
  • Use of immunosuppressive drugs within 30 days prior to study enrollment, not including topical or inhaled steroids/cytotoxic agents.
  • History of anaphylactic shock, asthma, urticaria, or other allergic or hypersensitivity reactions following vaccination.
  • History of severe allergic disorders or autoimmune connective tissue disorders, including rheumatoid arthritis. A high sensitivity C-Reactive Protein (CRP) test at screening will be used as part of the assessment of autoimmune disorders by the Principal Investigator.
  • Use of systemic antibiotics within 72 hours prior to study enrollment.
  • History of cirrhosis.
  • Positive results of testing for HepBsAg, Hepatitis C or HIV-1 or HIV-2 antibodies.
  • Positive results of drug screen (amphetamine, THC, cocaine).
  • Persons with antibody titer(s) of \>2 µg/mL to serogroup (s) A, C, Y, or W 135 as measured by ELISA.
  • +7 more criteria
