Trial Outcomes & Findings for CSL H1N1 Influenza Vaccine Administered at Two Dose Levels in Adult and Elderly Populations (NCT NCT00943488)

NCT ID: NCT00943488

Last Updated: 2012-10-31

Results Overview

Blood was collected from all participants prior to vaccination and at the 8-10 day follow up visit for testing in the HAI assay with Influenza H1N1 2009 virus as the assay antigen. A participant met the threshold of a 4-fold rise in titer if the Day 0 titer was less than 1:10 (the assay's lowest level of detection) and the Day 8-10 titer was 1:40 or greater, or the Day 0 titer was greater than or equal to 1:10 and the Day 8-10 titer was an increase by 4-fold or more.

PRIMARY outcome

Timeframe: Day 0-7 after first vaccination

Population: All participants receiving the first vaccination are included in the safety ITT cohort

Participants maintained a memory aid to record daily the occurrence of local reactions of pain, tenderness and swelling for 8 days after vaccination (Day 0-7) based on their interference with daily activities, with a severity grade of mild meaning no interference, moderate as some interference and severe as significant interference/prevented daily activity. Participants are counted if they reported experiencing the symptom at any severity on any of the 8 days.

Participants maintained a memory aid to record daily the occurrence of local reactions of swelling and redness for 8 days after vaccination (Day 0-7). If the reaction was present, the maximum diameter was measured in millimeters (mm). Participants are counted if they reported experiencing the reaction with any measurement greater than 0 mm on any of the 8 days.

Serious adverse events included any untoward medical occurrence that resulted in death; was life threatening; was a persistent/significant disability/incapacity; required in-patient hospitalization or prolongation thereof; resulted in a congenital anomaly/birth defect; or may have jeopardized the participant or required intervention to prevent one of these outcomes. Association to vaccination was determined by a study clinician licensed to make medical diagnoses.

Timeframe: Day 0 prior to first vaccination and Day 21 after the second vaccination

Population: Participants were included in the analyses if they received the first vaccination and had blood collected at the timepoint. Participants were analyzed as treated and restricted to age stratum. One participant was excluded due to presumed natural Influenza H1N1 infection, and four due to receiving non-study vaccines prior to the visit.

Blood was collected from all participants prior to the initial vaccination and 21 days after the second vaccination for testing in the HAI assay with Influenza H1N1 2009 virus as the assay antigen. A participant met the threshold of a 4-fold rise in titer if the Day 0 titer was less than 1:10 (the assay's lowest level of detection) and the Day 21 post vaccination 2 titer was 1:40 or greater, or the Day 0 titer was greater than or equal to 1:10 and the Day 21 post vaccination 2 titer was an increase by 4-fold or more.

Timeframe: Day 8-10 after the second vaccination

Population: Participants were included in the analyses if they received both vaccinations, with the second vaccination given within 4 days of the window, and had blood collected at both timepoints. Participants were analyzed as treated. This outcome measure restricts to age stratum.

Blood was collected from all participants at Day 8-10 post second vaccination for testing in the HAI assay with Influenza H1N1 2009 virus as the assay antigen. Each sample was tested at least twice according to standard operating procedures and the result of each replicate reported. A participant is counted if the geometric mean of the replicate values was 1:40 or greater.
