Study Endpoints

Primary Endpoints

Percentage of Participants With Seroconversion to Vaccine Antigens Following Concomitant Administration of Japanese Encephalitis Chimeric Virus Vaccine (JECV) and MMR or Single Administration of JE-CV and MMR Vaccine at 42 Days Following First Vaccination
Day 0 (pre-vaccination) and Day 42 post-vaccination

JE-CV antigens were measured using a 50% plaque reduction neutralization test (PRNT50); MMR antigens were measured using enzyme linked immunosorbent assay (ELISA). Seroconversion was defined as: for JE-CV - participants with a pre-vaccination titer \<1/10 and post-vaccination titer ≥1/10, or a pre-vaccination titer ≥1/10 and 4-fold increase from pre- to post; for Measles - post-vaccination titer ≥120 mIU/ml, when pre-vaccination titer is \<120 mIU/ml; for Mumps - post-vaccination titer ≥1/10 U/ml when pre-vaccination titer is \<10 U/ml; and for Rubella, post-vaccination titer ≥1/10 U/ml when pre-vaccination titer is \<10 U/ml.

Frequently asked questions about Japanese encephalitis chimeric virus: Measles, mumps, and rubella live attenuated virus

What is the Japanese encephalitis chimeric virus and measles, mumps, and rubella live attenuated virus combination?

It is a study combination of a Japanese encephalitis chimeric virus vaccine given together with a live attenuated measles, mumps, and rubella vaccine. The combination was evaluated in healthy toddlers to assess whether the two vaccines could be administered together. It targets prevention of Japanese encephalitis along with measles, mumps, and rubella.

What is this Japanese encephalitis chimeric virus and MMR combination used for?

It is used for immunization against Japanese encephalitis, measles, mumps, and rubella. The Phase 3 study enrolled healthy toddlers from 12 months of age in Taiwan to evaluate co-administration of the Japanese encephalitis chimeric virus vaccine with the measles, mumps, and rubella vaccine. The program falls within infectious disease prevention.

Who is developing the Japanese encephalitis chimeric virus and MMR combination?

Sanofi is the developer of this Japanese encephalitis chimeric virus and measles, mumps, and rubella vaccine combination. Sanofi trades on the New York Stock Exchange under the ticker SNY. The company sponsored the Phase 3 co-administration study conducted in Taiwanese toddlers.

What phase is the Japanese encephalitis chimeric virus and MMR combination in?

The combination has been studied in Phase 3. One Phase 3 trial has been completed, and no trials are currently active. The program is investigational and is not an approved product. The completed study was randomized and controlled, with 542 participants enrolled.

What clinical trial studied the Japanese encephalitis chimeric virus vaccine with the MMR vaccine?

The trial is NCT01188343, titled Study of Japanese Encephalitis Chimeric Virus Vaccine Given With Measles-Mumps-Rubella Vaccine in Taiwanese Toddlers. It was a completed Phase 3 randomized, controlled study that enrolled 542 healthy toddlers aged 12 months and older in Taiwan. It was not double blind and did not use biomarker selection.
