A Study to Evaluate the Reactogenicity, Safety and Immunogenicity of GlaxoSmithKline (GSK) Biologicals' Investigational Supra-seasonal Universal Influenza Vaccines - Inactivated (SUIVs) (GSK3816302A) in Healthy Adults Aged 18 to 39 Years

Completed · Phase 1 · Has a placebo group

Conditions studied: Influenza, Human

In brief

The purpose of this study is to assess the reactogenicity, safety and immunogenicity of different formulations of GlaxoSmithKline (GSK) Biologicals' investigational supra-seasonal universal influenza vaccines (SUIVs) (unadjuvanted or adjuvanted) in 18 to 39 year-old healthy subjects. Subjects will be enrolled and vaccinated with one or 2 primary dose(s) followed by a booster dose one year later.

Who can join

Age: 18 and older, up to 39. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Subjects who, in the opinion of the investigator, can and will comply with the requirements of the protocol.
• Written informed consent obtained from the subject prior to performance of any study specific procedure.
• A male or female between, and including, 18 and 39 years of age at the time of the first vaccination.
• Healthy subjects without acute or chronic, clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as established by medical history and clinical examination before first vaccination and laboratory screening tests (the latter being only applicable for subjects enrolled in Phase I).
• Subjects with no history of influenza vaccination within 6 months prior to first study vaccination and who are willing to forego any influenza vaccination during the entire study period.
• Female subjects of childbearing potential may be enrolled in the study, if the subject:
• Has practiced adequate contraception for 30 days prior to first vaccination, and
• Has a negative pregnancy test on the day of vaccination, and
• Has agreed to continue adequate contraception during the entire treatment period and for 2 months after completion of the vaccination series (last vaccination at Month 14).

You may not qualify if…

• Use of any investigational or non-registered product other than the study vaccines during the period starting 30 days before the first dose of study vaccines, or planned use during the study period.
• Any medical condition that in the judgment of the investigator would make intramuscular injection unsafe.
• Chronic administration of immunosuppressants or other immune-modifying drugs during the period starting 6 months prior to the first vaccine dose. For corticosteroids, this will mean prednisone ≥ 20 mg/day, or equivalent. Inhaled and topical steroids are allowed.
• Administration of long-acting immune-modifying drugs within 6 months before first vaccination, or planned administration any time during the study period.
• Planned administration/administration of a vaccine not foreseen by the study protocol in the period starting 30 days before the first dose up to the blood sampling at Day 85 and in the period starting 30 days before booster vaccination at Month 14 up to the blood sample at Month 14 + 28 days.
• Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational vaccine/product.
• Previous vaccination against influenza within the 6 months preceding the first vaccination at Visit 1 or planned use of such vaccines during the study period.
• History of vaccination with a (pre)pandemic influenza vaccine other than an H1N1pdm09 vaccine or history of laboratory-confirmed influenza infection other than seasonal or H1N1pdm09 influenza.
• Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
• History of or current autoimmune disease.
• Subjects diagnosed with excessive daytime sleepiness or narcolepsy; or history of narcolepsy in a subject's parent or sibling.
• History of Guillain-Barré syndrome.
• History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccines; a history of anaphylactic-type reaction to consumption of eggs; or a history of severe adverse reaction to a previous influenza vaccine.
• Hypersensitivity to latex.
• Acute disease and/or fever at the time of enrolment.
• Fever is defined as temperature ≥ 38.0°C / 100.4°F. The preferred location for measuring temperature in this study will be the oral cavity.
• Subjects with a minor illness without fever may be enrolled at the discretion of the investigator.
• For subjects with acute disease and/or fever at the time of enrolment, Visit 1 may be re-scheduled within the allowed time-window.
• Administration of immunoglobulins and/or any blood products during the period starting 3 months before the first dose of study vaccines or planned administration during the study period.
• Blood donation within 30 days before the first study blood sampling or planned blood donation within 30 days before and up to 30 days after any study blood sampling.
• Pregnant or lactating female.
• History of chronic alcohol consumption and/or drug abuse as deemed by the investigator to render the potential subject unable/unlikely to provide accurate safety reports.
• Female planning to become pregnant or planning to discontinue contraceptive precautions.
• Additional criterion applicable for Phase I subjects:
• Hematological and/or biochemical parameters outside the laboratory normal ranges, unless the laboratory abnormalities are considered not clinically significant by the investigator.
