入选标准
- •Male or female, 18 to 49 years of age (not yet reached their 50th birthday) at the time of randomization
- •Healthy by medical history and physical examination
- •Written informed consent and any locally required authorization (eg, Health Insurance Portability and Accountability Act [HIPAA] in the United States of America [USA], European Union [EU] Data Privacy Directive in the EU) obtained from the subject/legal representative prior to performing any protocol-related procedures, including screening evaluations
- •Females of childbearing potential, (ie, unless surgically sterile [eg, bilateral tubal ligation, bilateral oophorectomy, or hysterectomy], has sterile male partner, is at least 1 year post menopause, or practices abstinence) must use an effective method of avoiding pregnancy (including oral, transdermal, or implanted contraceptives, intrauterine device, female condom with spermicide, diaphragm with spermicide, cervical cap, or use of a condom with spermicide by the sexual partner) for 30 days prior to the first dose of investigational product, and must agree to continue using such precautions for 60 days after the second dose of investigational product. In addition, the subject must also have a negative urine or blood pregnancy test at screening and, if screening and Day 1 do not occur on the same day, on the day of vaccination prior to randomization.
- •Males, unless not sexually active, must use an effective method of birth control with a female partner and must agree to continue using such contraceptive precautions for at least 30 days after the second dose of investigational product (from Day 1 through Day 59 of the study)
- •Subject is available by telephone
- •Subject is able to understand and comply with the requirements of the protocol, as judged by the investigator
- •Subject is able to complete follow-up period of 180 days after Dose 2 as required by the protocol
排除标准
- •History of hypersensitivity to any component of the investigational product including egg or egg protein, gelatin or arginine, or serious, life-threatening, or severe reactions to previous influenza vaccinations
- •History of hypersensitivity to gentamicin
- •Any condition for which the inactivated influenza vaccine is indicated, including chronic disorders of the pulmonary or cardiovascular systems (eg, asthma), chronic metabolic diseases (eg, diabetes mellitus), renal dysfunction, or hemoglobinopathies that required regular medical follow-up or hospitalization during the preceding year
- •Acute febrile (> 100.0°F oral or equivalent) and/or clinically significant respiratory illness (eg, cough or sore throat) within 14 days prior to randomization
- •History of asthma
- •Any known immunosuppressive condition or immune deficiency disease, including human immunodeficiency virus infection, or ongoing immunosuppressive therapy
- •History of Guillain-Barré syndrome
- •A household contact who is severely immunocompromised (eg, hematopoietic stem cell transplant recipient, during those periods in which the immunocompromised individual requires care in a protective environment); subject should additionally avoid close contact with severely immunocompromised individuals for at least 21 days after receipt of investigational product
- •Receipt of any investigational agent within 30 days prior to randomization, or expected receipt through 30 days after the second dose of investigational product (use of licensed agents for indications not listed in the package insert is permitted)
- •Expected receipt of antipyretic or analgesic medication on a daily or every other day basis from randomization through 14 days after receipt of each dose of investigational product
- •Administration of intranasal medications within 14 days prior to randomization, or expected receipt through 14 days after administration of each dose of investigational product
- •Receipt of any nonstudy vaccine within 30 days before or after Dose 1 or expected receipt of any nonstudy vaccine within 30 days before or after Dose 2
- •Known or suspected mitochondrial encephalomyopathy
- •Subject is pregnant or a nursing mother
- •Any condition (eg, chronic cough, allergic rhinitis) that, in the opinion of the investigator, would interfere with evaluation of the investigational product or interpretation of subject safety or study results
- •Subject or immediate family member of subject is an employee of the clinical study site or is otherwise in involved with the conduct of the study
结局指标
主要结局
Number of Participants With Fever Post Dose 1 (Days 1-8), Defined as an Oral Temperature ≥ 101°F (38.3°C).
时间窗: Days 1-8
The number of participants with fever between the two treatment groups was compared based on the upper limit of the two-sided 95% exact confidence intervals (CIs) for the rate difference (Vaccine minus Placebo). The upper limit of the two-sided 95% CI was evaluated against the prespecified equivalence criterion of 10% which corresponded to the following hypotheses • H0 (null): rate difference ≥ 10% • HA (alternative): rate difference \< 10%
Number of Participants Who Experienced a Post Dose 1 (Day 15) Seroresponse Against the H1N1 Strain in All Participants Regardless of Baseline Serostatus
时间窗: Day 1, Day 15
Seroresponse was defined as a ≥ 4-fold rise in hemagglutination inhibition (HAI) titer from baseline. All immunogenicity analyses were based on the immunogenicity population.
Number of Participants Who Experienced a Post Dose 1 (Day 29) Seroresponse Against the H1N1 Strain in All Participants Regardless of Baseline Serostatus
时间窗: Day 1, Day 29
Seroresponse was defined as a ≥ 4-fold rise in HAI titer from baseline. All immunogenicity analyses were based on the immunogenicity population.
Number of Participants Who Experienced a Post Dose 2 (Day 57) Seroresponse Against the H1N1 Strain in All Participants Regardless of Baseline Serostatus
时间窗: Day 1, Day 57
Seroresponse was defined as a ≥ 4-fold rise in HAI titer from baseline. All immunogenicity analyses were based on the immunogenicity population.
