Detailní popis
This study is a phase 2, single dose study of TAK-850 (cell-culture derived TIV) administered subcutaneously in healthy Japanese adults, designed as a randomized, double-blind, parallel-group, comparative study to evaluate the immunogenicity and safety compared to an egg-derived TIV.
The drug being tested in this study is called TAK-850. TAK-850 was tested in healthy volunteers. This study looked at immunogenicity and safety of TAK-850 (cell-derived) compared to an egg-derived influenza vaccine.
The study enrolled 400 patients. Participants were randomly assigned (by chance, like flipping a coin) to one of the two groups-which will remain undisclosed to the patient and study doctor during the study (unless there is an urgent medical need):
- TAK-850
- Influenza HA vaccine All participants received one injection. This single center trial was conducted in Japan. The overall time to participate in this study was 22 days. Participants made multiple visits to the clinic, including a final visit 21 days after the vaccination for a follow-up assessment.

Seroconversion Rate of Hemagglutination Inhibition (HI) Antibody Titer (Egg-Derived Antigen)
Časové okno: Baseline and Day 22
|
Seroconversion rate was measured by hemagglutination inhibition (HI) antibody titer (egg-derived antigen) for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain), 21 days after vaccination. Seroconversion rate was defined as the percentage of participants achieving a minimal 4-fold increase from the Baseline HI antibody titer in participants with a Baseline titer ≥10, or achieving an HI antibody titer of ≥40 in participants with a Baseline titer <10. |
