Frequently asked questions about Meningococcal Polysaccharide Diphtheria Toxoid Conjugate: Menactra

What is Menactra used for?

Menactra is a vaccine used to prevent meningitis and meningococcal infection caused by meningococcal groups A, C, Y and W-135. It is a meningococcal polysaccharide diphtheria toxoid conjugate vaccine developed by Sanofi. Clinical studies have evaluated it in healthy volunteers, including adults and children, for protection against these meningococcal serogroups.

Who makes Menactra?

Menactra is made by Sanofi, which trades under the ticker SNY. Sanofi is the developer of this meningococcal polysaccharide diphtheria toxoid conjugate vaccine.

What phase is Menactra in?

Menactra has been studied in Phase 3 clinical development. Two completed trials are registered, one Phase 2 and one Phase 3, with a combined enrollment of 957 participants. The Phase 3 trial evaluated two doses of Menactra or one dose of a monovalent meningococcal group C vaccine alongside routine immunizations.

What clinical trials is Menactra in?

Menactra has been evaluated in two completed clinical trials: NCT01442675, a Phase 2 study of a single dose of Menactra vaccine 4 to 6 years after a prior Menactra dose, and NCT01359449, a Phase 3 study of two doses of Menactra or one dose of monovalent meningococcal group C vaccine with routine immunizations.
