Safety Study of Group A, C, Y & W-135 Meningococcal Polysaccharide Diphtheria Toxoid Conjugate Vaccine for Meningitis

Completed · Phase 1

Conditions studied: Meningococcal Meningitis, Meningococcal Infections

In brief

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.

• 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.

• 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.

• 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).

• Unable to understand all of the study requirements.
• Prisoners.
• Participation in a clinical trial in the last three months.
• History of any serious chronic medical or psychiatric illnesses.
• History of significant head trauma, alcohol or substance abuse or other medical illnesses that could cause a neurological deficit (e.g., cerebro-vascular disease) .
• Chronic medication use that, in the opinion of the Investigator, may influence or bias the clinical outcome of the trial.
