A Phase I/IIa Study of GC3110A (Quadrivalent Influenza Vaccine)

연구 개요

The purpose of this study is to determine whether GC3110A (a QIV) is effective compared to GC Flu Pre-filled Syringe Inj. (a marketed TIV) after single intramuscular administration in Korean healthy adults. The comparator, GC Flu pre-filled syringe inj. is a trivalent influenza vaccine (TIV) including viruses representing 3 influenza strains (one A/HIN1, one A/H3N2, and one B). However, two antigenically distinct lineages of influenza B (Victoria and Yamagata) co-circulate annually in the United States. Predicting which lineage of influenza B will predominate during a season is challenging, and cross-protection by immunization against the other lineage is expected to be low. One proposed alternative is to produce a quadrivalent influenza vaccine (QIV) including an influenza B virus from each of the two circulating lineages. GC3110A is a new quadrivalent influenza vaccine (QIV), which contains all of 4 vaccine components WHO recommends for use in the 2013-14 influenza season (northern hemisphere winter) and includes two influenza B viruses. GC3110A is expected to show the additional public health benefit compared with traditional TIV.
