Trial Outcomes & Findings for Phase 1/2 Study of TAK-850 Intramuscular Injection in Healthy Pediatric Participants (NCT NCT02367885)

NCT ID: NCT02367885

Last Updated: 2016-04-07

Results Overview

Local reactions and systemic events were recorded using a diary. Number of participants with local reactions (Injection site tenderness, Injection site ecchymosis, Irritability postvaccinal) and systemic events (Pyrexia, sweaty, vomiting, crying abnormal, inappetence, somnolence, sleeplessness) were reported. Participants may be represented in more than 1 category.

Participant Flow

Participants took part in the study at 2 investigative sites in Japan from 14 February 2015 to 2 May 2015.

Healthy pediatric participants of age group 6 months-19 years were enrolled in 1 of the 3 treatment groups: TAK-850 0.25 milliliter (mL): 6 - 35 months; TAK-850 0.5 mL: 3-12 Years and TAK-850 0.5 mL: 13-19 Years.

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 (example, 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. A SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; or congenital anomaly; or a medically important event. AEs included both SAE and non-SAE.

Seroconversion rate was defined as the percentage of participants achieving a minimal 4-fold increase from baseline (with a baseline HI antibody titer of \>=10), or achieving a HI antibody titer of \>=40 (with a baseline HI antibody titer of \<10) for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain).

SECONDARY outcome

Timeframe: Day 22 (21 days after Vaccination 1 for all groups), Day 43 (21 days after Vaccination 2 for 6-35 months old group and 3-12 years old group)

Population: All participants included in the FAS (all participants who received at least 1 dose of study vaccination) who had data available for specified strain at specified post-baseline time points.

Seroconversion rate was measured by SRH antibody titer (Vero antigen) for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain), 21 days after each vaccination for all groups. Seroconversion rate was defined as the percentage of participants achieving a minimal 50% increase from baseline (with a baseline SRH antibody titer of \>4 mm\^2), or achieving a SRH antibody titer of \>=25 mm\^2 (with baseline SRH antibody titer of \<=4 mm\^2) for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain). Analysis after Vaccination 2 is only applicable for 6-35 months old group and 3-12 years old group.
