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

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.

About this study

This study is the first in human trial of GC3110A and is designed as an adaptive Phase I/IIa to ensure participants protection. Part A is an open-label and single arm study in 9 healthy volunteers. Data and Safety Monitoring Board (DSMB) will review the solicited/unsolicited adverse events conditionally if any toxicity of Grade 3 or 4 has been reported during 7 days after vaccination. Part B is a randomized (2:1), double-blind, active controlled study and a total of 75 volunteers will participate in this part. Adverse events assessment will be done according to the 'Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials'.
