Trial Outcomes & Findings for A Study to Evaluate the Shedding and Safety of Trivalent Influenza Virus Vaccine Live, Intranasal in Infants and Young Children (NCT NCT00344305)

NCT ID: NCT00344305

Last Updated: 2017-07-24

Results Overview

Viral shedding is defined as the detection of virus by viral culture and vaccine-type virus was confirmed by polymerase chain reaction (PCR) based assays. Viral shedding (A/New Caledonia/20/99 \[H1N1\]; A/Wyoming/03/2003 \[H3N2\] (A/Fujian/411/2002-like); B/Jilin/20/2003 B/Shanghai/361/2002-like\]) was measured from samples obtained from nasal swabs daily from Days 1 to 7 post vaccination and approximately every other day thereafter from Days 9 to 28. Participants whose Day 25 or 28 shedding sample was positive for vaccine virus had additional shedding samples collected approximately every 7 days, or as soon as possible upon awareness of culture positivity, until 2 consecutive samples were negative for vaccine virus.

Participant Flow

A total of 200 participants were enrolled in the study from 15-May-2006 through 22-Jun-2006 at 16 sites in the United States of America.

A total of 200 participants were stratified on the basis of their age into two cohorts: Cohort 1 (participants aged between 6 to less than \[\<\] 24 months) and Cohort 2 (participants aged between 24 to \< 60 months).

Cohort 1: Participants Between 6 to < 24 Months Age
Participants received a single, intranasal dose of 0.2 millilitre (mL) (approximately 0.1 mL in each nostril FluMist trivalent influenza virus vaccine live on Day 0 of the study. Each dose of FluMist vaccine contained 10\^7 fluorescent focus units (FFU) of three influenza virus strains namely, A/New Caledonia/20/99 (H1N1), A/Wyoming/03/2003 (H3N2) (A/Fujian/411/2002-like) and B/Jilin/20/2003 (B/Shanghai/361/2002-like).
Cohort 2: Participants Between 24 to < 60 Months Age
Participants received a single, intranasal dose of 0.2 mL (approximately 0.1 mL in each nostril) FluMist trivalent influenza virus vaccine live on Day 0 of the study. Each dose of FluMist vaccine contained 10\^7 FFU of three influenza virus strains namely, A/New Caledonia/20/99 (H1N1), A/Wyoming/03/2003 (H3N2) (A/Fujian/411/2002-like) and B/Jilin/20/2003 (B/Shanghai/361/2002-like).

Population: Shedding population: all participants who received a full dose of study drug and had assay results from nasal specimens obtained at any post-dosing time point. Here, number of participants analyzed signified those participants who were evaluable for this outcome and "n" signified those participants who were evaluable for a specified category.

The genetic and phenotypic stability of shed vaccine virus was evaluated by determination of genomic sequence and assessment of the cold-adapted (ca) and temperature-sensitive (ts) phenotypes. Viruses were considered ts if their titer at 39 degrees Celsius (°C) was at least two logs (100-fold) lower than their titer at 33°C. Viruses were considered ca if they replicated at 25°C to a titer that was no more than two logs (100-fold) lower than the titer at 33°C. After additional phenotypic and genotypic analyses, all evaluable samples retained the ca and ts phenotypes.

An SAE was 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; congenital anomaly. An SNMC is defined as a newly diagnosed medical condition that was of a chronic, ongoing nature and was assessed by the investigator as medically significant. SNMCs included, but were not limited to, diabetes, asthma, autoimmune disease (lupus, rheumatoid arthritis), and neurological disease (epilepsy, autism).
