入选标准
- •Male or female adults who are 18 to 64 years of age (inclusive) at the time of first study vaccination.
- •Written informed consent obtained from subject.
- •Subjects who the investigator believes can and will comply with the requirements of the protocol .
- •Healthy subjects as established by medical history and physical examination.
- •Access to a consistent means of telephone contact.
- •For subjects who undergo a screening visit: results of all safety laboratory tests obtained at the screening visit must be within reference ranges. Results of any repeat testing cannot be used to qualify a subject for enrolment.
- •Female subjects of non-childbearing potential may be enrolled in the study. Non-childbearing potential is defined as current tubal ligation, hysterectomy, ovariectomy or post-menopause.
- •Female subjects of childbearing potential may be enrolled in the study, if they
- •have practiced adequate contraception for 30 days prior to vaccination, and
- •have a negative pregnancy test on the day of vaccination, and
- •agree to continue to practice adequate contraception until 2 months after the last dose administered.
排除标准
- •Presence or evidence of neurological or psychiatric diagnoses which, although stable, are deemed by the investigator to render the potential subject unable/unlikely to provide accurate safety reports.
- •Presence or evidence of substance abuse.
- •Diagnosed with cancer, or treatment for cancer within three years.
- •Diagnosed with excessive daytime sleepiness, or narcolepsy; or history of narcolepsy in a subject's parent, sibling or child.
- •Presence of a temperature ≥ 38.0ºC (≥100.4ºF), or acute symptoms greater than "mild" severity on the scheduled date of first vaccination.
- •Any confirmed or suspected immunosuppressive or immunodeficient condition including history of human immunodeficiency virus (HIV) infection.
- •Receipt of systemic glucocorticoids within 30 days prior to the first dose of study vaccine/placebo, or any other cytotoxic, immunosuppressive or immune-modifying drugs within 6 months of first study vaccine/ placebo dose.
- •Any significant disorder of coagulation or treatment with warfarin derivatives or heparin.
- •An acute evolving neurological disorder or Guillain Barré Syndrome within 42 days of receipt of prior seasonal or pandemic influenza vaccine.
- •Administration of an inactive vaccine within 14 days or of a live attenuated vaccine within 30 days before the first dose of study vaccine/placebo.
- •Planned administration of any vaccine other than the study vaccine/placebo before blood sampling at the Day 42 visit.
- •Previous administration of any H7 vaccine or physician-confirmed H7 disease.
- •Use of any investigational or non-registered product other than the study vaccine within 30 days preceding the first dose of study vaccine/placebo, or planned use during the study period.
- •Receipt of any immunoglobulins and/or any blood products within 90 days before the first dose of study vaccine/placebo, or planned administration of any of these products during the study period.
- •Any known or suspected allergy to any constituent of influenza vaccines or component used in the manufacturing process of the study vaccine including a history of anaphylactic-type reaction to consumption of eggs; or a history of severe adverse reaction to a previous influenza vaccine.
- •Known pregnancy or a positive urine beta-human chorionic gonadotropin (β-hCG) test result before the first dose of study vaccine/placebo.
- •Lactating or nursing women.
- •Any condition which, in the opinion of the investigator, prevents the subject from participating in the study.
结局指标
主要结局
Humoral immune response in terms of vaccine-homologous hemagglutination inhibition (HI) antibody titers
时间窗: At Day 42
The following aggregate variables will be calculated for each adjuvanted H7N9 vaccine group: • Seroconversion rates (SCR); • Seroprotection rates (SPR); • Mean Geometric Increase (MGI)
Occurrence of each solicited general symptom
时间窗: During a 7-day follow-up period (i.e., day of vaccination and 6 subsequent days) after each vaccination
Occurrence of clinical safety laboratory abnormalities reported for samples
时间窗: At Day 42 visit
Occurrence of unsolicited adverse events
时间窗: 21 days after each dose
Occurrence of Medically Attended Adverse Events (MAEs), potential Immune Mediated Diseases (pIMDs) and Serious Adverse Events (SAEs)
时间窗: From Day 0 until the Day 42
Occurrence of each solicited local symptom
时间窗: During a 7-day follow-up period (i.e., day of vaccination and 6 subsequent days) after each vaccination
次要结局
- Humoral immune response in terms of vaccine-homologous (H7N9) HI antibody titers(GMTs and Seropositivity rates at Days 0, 21, 42 and Months 6 and 12; SCR and MGI at Day 21, 42 (Placebo group only) and Months 6 and 12; SPR at Days 0, 21, 42 (Placebo group only) and Months 6 and 12)
- Humoral immune response in terms of vaccine homologous (H7N9) neutralizing (MN) antibody titers(GMTs and Seropositivity rates at Days 0, 21, 42 and Month 6; VRR at Days 21, 42 and Month 6)
- Occurrence of MAEs, pIMDs and SAEs(Until the Month 12 visit)
- Humoral immune response in terms of vaccine-homologous (H7N9) HI antibody titers by age stratum(GMTs, Seropositivity rates and SPR at Days 0, 21, 42 and Months 6 and 12; SCR and MGI at Day 21, 42 and Months 6 and 12)
- Humoral immune response in terms of vaccine-homologous hemagglutination inhibition (HI) antibody titers(At Day 42)
