Clinical Trial Summary

The purpose of this study is to evaluate the safety and immunogenicity of a single subcutaneous injection of TAK-850 as compared to intramuscular injection of TAK-850 in healthy Japanese adults

Description:

The drug being tested in this study is called TAK-850. This drug is being tested to evaluate the safety and immunogenicity of a single subcutaneous injection as compared to a single, intramuscular injection.

A total of 110 healthy participants (55 per group) will take part in this study.

Each participant will be randomly (like flipping a coin) assigned to receive one of the following :

• A single injection of TAK-850, subcutaneously , or

• A single injection of TAK-850, intramuscularly.

Participants will make up to 3 visits to the study site. Total duration of this study is 22 days.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants Reporting Solicited Local and Systemic Adverse Events (AEs)	Number of participants with local reactions (injection site pain, injection site redness, injection site swelling, injection site induration, injection site tenderness, and injection site ecchymosis) and systemic events (pyrexia, malaise, chills, fatigue, headache, sweaty, myalgia, arthralgia, nausea and vomiting) were reported using an electronic diary.	Up to 21 days (Day 22) after vaccination	Yes
Primary	Number of Participants Who Experience at Least One Treatment Emergent Adverse Event (TEAE)	An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A TEAE is defined as an adverse event with an onset that occurs after receiving study drug.	Up to 21 days (Day 22) after vaccination	Yes
Primary	Percentage of Participants With Seroprotection in Hemagglutination Inhibition (HI) Antibody Titer (Egg-derived Antigen) of >=40.
