- receipt of immunostimulants within the past 6 months,
- receipt of parenteral immunoglobulin preparation, blood products, and/or plasma derivates within the past 3 months and for the full length of the study, or
- suspected or known human immunodeficiency virus (HIV) infection or HIV related disease
▫ Has known or suspected drug or alcohol abuse within the past 2 years;
▫ Has bleeding diathesis or conditions associated with prolonged bleeding time that, in the investigator’s opinion, would interfere with the safety of the subject;
▫ Is not able to comprehend and to follow all required study procedures for the whole period of the study;
▫ Has a history or any illness that, in the opinion of the investigator, would pose additional risk to the subjects because of participation in the study;
▫ Has the following within the past 6 months:
- had any laboratory confirmed seasonal or pandemic influenza disease
- received any seasonal or pandemic influenza vaccine
▫ Has received any other vaccine within 4 weeks prior to enrollment in this study or who are planning to receive any vaccine during the study;
▫ Has acute or chronic infections requiring antiviral therapy within the last 7 days;
▫ Has experienced fever (ie, body temperature [preferably oral] ≥38.0°C) within the last 3 days of intended study vaccination;
▫ Has been participating in any clinical trial with another investigational product 4 weeks prior to first study visit or intends to participate in another clinical study at any time during the conduct of this study;
▫ Is part of study personnel or has close family members conducting this study;
▫ Has a body mass index (BMI) >35 kg/m2 (BMI is calculated by dividing the subject’s weight in kilograms by the subject’s height in meters multiplied by the subject’s height in meters);
▫ Is pregnant (confirmed by positive urine pregnancy test) or nursing (breastfeeding) or is a female of childbearing potential who refuses to use an acceptable method of birth control for the whole duration of the study.
Female of childbearing potential is defined as a post onset menarche and premenopausal female capable of becoming pregnant. This does not include females who meet any of the following conditions: (1) menopause at least 2 years earlier, (2) tubal ligation at least 1 year earlier, or (3) bilateral oophorectomy or hysterectomy.
Reliable birth control method is defined as hormonal (eg, oral, injection, transdermal patch, implant, cervical ring), barrier (eg, condom with spermicide or diaphragm with spermicide), intrauterine device (eg, IUD), monogamous relationship with partner who has been vasectomized for 6 months or more prior to the subject’s study entry, or sexual abstinence for 2 months or more prior to the subject’s study entry and agreement at enrollment to continue abstinence through day 22 ( 1/+3) of the study.

E.5 End points |
E.5.1 | Primary end point(s) |
Immunogenicity Endpoints:
Antibody responses will be evaluated by the SRH assay according to the following endpoints:
▫ The percentage of subjects with SRH area ≥25 mm2
▫ The percentage of subjects achieving seroconversion or significant increase by SRH area
- Seroconversion is defined as day 1 SRH area with a negative result (SRH area ≤4 mm2) and day 22 ( 1/+3) SRH area ≥25 mm2
- Significant increase is defined as a positive day 1 SRH area (SRH area >4 mm2) and at least a 50% increase in SRH area on day 22 ( 1/+3)
▫ Geometric mean ratio (GMR) day 22 ( 1/+3)/day 1
Antibody responses will be evaluated by the HI assay according to the following endpoints:
▫ The percentage of subjects with HI titer ≥1:40
▫ The percentage of subjects achieving seroconversion or significant increase in HI titer
- Seroconversion is defined as day 1 HI titer <1:10 and day 22 ( 1/+3) HI titer ≥1:40
- Significant increase is defined as day 1 HI titer ≥1:10 and at least a 4-fold increase in HI titer on day 22 ( 1/+3)
▫ GMR day 22 ( 1/+3)/day 1 |

|
E.5.2 | Secondary end point(s) |
Safety Endpoints:
Safety endpoints are based on solicited and unsolicited AEs.
The measures for assessing safety are as follows:
▫ Percentages of subjects with solicited local and systemic AEs and other solicited events as measured for 4 days (day 1 through day 4, inclusive) following vaccination
- Calculated for 2 time intervals after vaccination: 30 minutes, day 1 (after 6 hours) through day 4 (inclusive, ie, excluding the observations at 30 minutes)
▫ Percentages of subjects with any unsolicited AEs reported for 4 days (day 1 through day 4, inclusive) following vaccination
▫ Percentages of subjects reporting unsolicited SAEs, medically attended AEs, AEs leading to withdrawal from the study, and concomitant medications/vaccinations associated with these events as collected from day 1 through day 22 ( 1/+3)
Solicited local AEs will include injection-site induration, erythema, ecchymosis, and pain.
Solicited systemic AEs will include fever (derived from measured body temperature [preferably oral] ≥38.0°C), shivering/chills, myalgia, arthralgia, headache, fatigue, and malaise.
Other solicited AEs will include use of analgesic/antipyretic medication before and after vaccination in response to fever or pain. |
