Brief Summary:
The purpose of this study is to investigate the effectiveness safety and tolerability of an influenza vaccine Influenza is a highly infectious disease that occurs throughout the world in the winter months Infection with an influenza virus is a major public health threat as it has the ability to spread rapidly and affect large numbers of people Up to 1359 healthy adults ages 18 to less than 65 years old will participate in this study for up to 24 days Volunteers will receive an injection of either influenza vaccine with thimerosal vaccine without thimerosal or placebo with thimerosal Volunteers will be asked to document information about any health changes for 21 days following vaccination Volunteers will return to the clinic on days 5 and 21 after vaccination to share this information with study staff On day 21 volunteers will have a physical examination Blood samples will be taken prior to vaccination and at Day 21 post-vaccination
Detailed Description:
The purpose of this Phase III randomized double-blinded placebo-controlled multi-center study is to evaluate the immunogenicity safety and tolerability of CSL Limited Inactivated Influenza Vaccine in adults ages 18 to less than 65 The primary objective of this study is to demonstrate that vaccination with CSL Limited Inactivated Influenza Vaccine produces an immune response sufficient to meet the Committee for Medicinal Products for Human Use CHMP criteria for young adults of 40 serorconversion and 70 seroprotection Secondary objectives are to demonstrate clinical consistency between 3 lots batches of CSL Limited Inactivated Influenza Vaccine multi-dose vial presentation Thimerosal containing to demonstrate clinical consistency between CSL Limited Inactivated Influenza Vaccine multi-dose vial presentation Thimerosal containing and CSL Limited Inactivated Influenza Vaccine pre-filled syringe presentation Thimerosal-free and to demonstrate acceptable safety and tolerability of CSL Limited Inactivated Influenza Vaccine multi-dose vial presentation Thimerosal containing and pre-filled syringe presentation Thimerosal-free Primary endpoints are seroprotection rate and seroconversion rate Seroprotection is defined as a minimum post-vaccination humagglutination inhibition HI titer of 140 and seroconversion is defined as an increase in HI antibody titer of at least 4-fold with a minimum post-vaccination HI titer of 140 Secondary endpoints are comparison of the Geometric Mean Titers to influenza hemagglutinin antigens post vaccination of the active treatment arms and the number and rate of the type frequency and intensity of adverse events AE in the active treatment arms Approximately 1250 and up to 1359 healthy adults ages 18 to less than 65 years old will be enrolled into this clinical trial Subjects who meet the inclusion criteria for the study will be randomized in a 11111 ratio to receive 1 of 3 lots of vaccine in multidose vials a single lot of vaccine in pre-filled syringes or placebo in multi-dose vials 250 subjects per group Vaccine will be prepared and administered by an unblinded vaccine administrator who will not be involved in subsequent assessments Subjects will be observed in the clinic for at least 30 minutes after vaccination and subjects will maintain a 5-day post-vaccination solicited AE and local reaction memory aid and a 21-day unsolicited AE memory aid Subjects will return to the clinic at day 5 to review their reactogenicity memory aid Subjects will also return to clinic on Day-21 post-vaccination for AE and concomitant medication assessment a targeted physical examination if indicated and a review of the memory aid Serum for antibody titers will be drawn prior to vaccination and on Day-21 post-vaccination Subjects will participate for up to 24 days
