NCT04732871

Brief Summary

The purpose of this study is to assess the safety, reactogenicity, immunogenicity and long-term persistence of immune response up to 5 years following a single dose vaccination of GSK's investigational vaccine RSVPreF3 OA, in adults aged 60 years and above. The study will also evaluate the immunogenicity, safety and reactogenicity of additional vaccine doses given according to different revaccination schedules.

Study Arms (3)

RSV_annual Group

EXPERIMENTAL

Participants receive one dose of RSVPreF3 OA investigational vaccine at Day 1 and 2 revaccination doses at 12 months post-Dose 1 and at 24 months post-Dose 1, respectively and are followed up until Month 60.

Biological: RSVPreF3 OA investigational vaccine

RSV_Flexible revaccination Group

EXPERIMENTAL

Participants receive one dose of RSVPreF3 OA investigational vaccine at Day 1 and 2 revaccination doses at 24 months post-Dose 1 and at 48 months post-Dose 1, respectively and are followed up until Month 60.

Biological: RSVPreF3 OA investigational vaccine

RSV_1dose Group

EXPERIMENTAL

Participants receive one dose of RSVPreF3 OA investigational vaccine at Day 1 and are followed up until Month 36. At Month 36, participants in this group will be re-randomized in 2 groups: RSV\_1dose\_M36 (which will receive 1 additional revaccination dose at Month 36 and will be followed up until Month 60) and RSV\_1dose\_Flexible (which will receive 1 additional revaccination dose at Month 60, and will be followed up until study end at Month 72).

Biological: RSVPreF3 OA investigational vaccine

Interventions

RSVPreF3 OA investigational vaccine administered intramuscularly in the deltoid region of the non-dominant arm.

Eligibility Criteria

Age60 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female participants ≥60 YOA at first vaccination, who live in the community (CD participants) or in a Long-term care facility (LTCF participants).
  • Participants who, in the opinion of the investigator, can and will comply with the requirements of the protocol.
  • Written or witnessed informed consent obtained from the participant prior to performance of any study specific procedure.
  • Participants who are medically stable in the opinion of the investigator at the time of first vaccination. Patients with chronic stable medical conditions with or without specific treatment, such as diabetes, hypertension or cardiac disease, are allowed to participate in this study if considered by the investigator as medically stable.

You may not qualify if:

  • Medical conditions
  • Any confirmed or suspected immunosuppressive or immunodeficient condition resulting from disease or immunosuppressive/cytotoxic therapy, based on medical history and physical examination.
  • History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine.
  • Hypersensitivity to latex.
  • Serious or unstable chronic illness.
  • Recurrent or un-controlled neurological disorders or seizures. Participants with medically-controlled active or chronic neurological diseases can be enrolled in the study as per investigator assessment, provided that their condition will allow them to comply with the requirements of the protocol.
  • Significant underlying illness that in the opinion of the investigator would be expected to prevent completion of the study.
  • Any medical condition that in the judgment of the investigator would make intramuscular injection unsafe.
  • Any history of dementia or any medical condition that moderately or severely impairs cognition.
  • Prior/Concomitant therapy
  • Use of any investigational or non-registered product other than the study vaccine during the period beginning 30 days before the first dose of study vaccine, or planned use during the study period.
  • Planned or actual administration of a vaccine not foreseen by the study protocol in the period starting 30 days before each dose and ending 30 days after each dose of study vaccine administration, with the exception of inactivated, split virion and subunit influenza vaccines which can be administered up to 14 days before or from 14 days after each study vaccination.
  • Previous vaccination with an RSV vaccine.
  • Administration of long-acting immune-modifying drugs or planned administration at any time during the study period.
  • Administration of immunoglobulins and/or any blood products or plasma derivatives during the period starting 90 days before the first dose of study vaccine or planned administration during the study period.
