Phase III Study of Intramuscular TAK-816 in Healthy Infants
A Phase III, Multicenter, Open-Label Study to Evaluate the Safety and Immunogenicity of Intramuscular TAK-816 in Healthy Infants
Study Overview
Status
Intervention / Treatment
Detailed Description
The vaccine being tested in this study is called TAK-816. TAK-816 was being tested to evaluate its safety and immune response after intramuscular (IM) injection with TAK-816. This study evaluated adverse events and the seroprotection rate and geometric mean titer (GMT) of anti-polyribosylribitol phosphate (PRP)-antibodies in participants who were administered TAK-816 IM.
The study enrolled 31 participants. All participants received 3 doses of TAK-816 IM at 4-week intervals as part of the primary vaccination and 1 booster vaccination 52 weeks after the third dose of the primary vaccination.
This multi-center trial was conducted in Japan. The overall time to participate in this study was 64 weeks. Participants made multiple visits to the clinic including a final visit 4 weeks after last dose of study drug for a follow-up assessment.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With Adverse Events
Time Frame: For 64 Weeks
|
Adverse events are defined as unfavorable and unintended signs, symptoms or diseases temporally associated with the use of a medicinal product, regardless of relationship to the medicinal product.
Among these, events which are considered possibly associated with a medicinal product are defined as adverse reactions.
|
For 64 Weeks
|
Number of Participants With Adverse Reactions Related to Body Temperature (Pyrexia)
Time Frame: For 64 Weeks
|
Body temperature was assessed for 14 days after each vaccination and was recorded by the caregiver in a diary.
Adverse reactions related body temperature was reported as pyrexia.
|
For 64 Weeks
|
Number of Participants With Adverse Reactions Related to Local Reactions
Time Frame: For 64 Weeks
|
Local Reactions were assessed 14 days after each vaccination and were recorded by the caregiver in a diary.
Local reactions (injection site) were erythema, swelling, induration and pain (tenderness).
|
For 64 Weeks
|
Number of Participants With Adverse Reactions Related to Systemic Reactions
Time Frame: For 64 Weeks
|
Systemic Reactions were assessed 14 days after each vaccination and were recorded by the caregiver in a diary.
Systemic reactions were rash, irritability, crying, decreased appetite, vomiting, diarrhoea, somnolence (sleepiness) and insomnia (sleeplessness).
|
For 64 Weeks
|
