A Long Term Follow-up Study up to 4 Years After Study Vaccination to Assess Immunogenicity and Safety of the Investigational Vaccine in Adults

March 12, 2021 updated by: GlaxoSmithKline

A Long-term Follow-up Study of the Investigational GSK Biologicals' GSK3277511A Vaccine in Adults

The purpose of this long-term follow-up of a Phase I study is to evaluate the kinetics of the antibody response to NTHi-Mcat antigens and long-term safety, in subjects aged between 50-71 years at the time of enrolment in the NTHi-Mcat-001 study. These subjects were previously exposed to two adjuvanted formulations of the NTHi-Mcat vaccine administered according to a 0, 2 months schedule in the NTHi-Mcat-001 (201281) study. The subjects that had received saline placebo controls will also be included in this follow-up study to make comparisons with the investigational vaccines. No vaccinations will be administered in this trial.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Subjects Reported With Any Serious Adverse Event (SAE)
Time Frame: From first visit (Month 20) up to study conclusion (Month 50)
A SAE is any untoward medical occurrence that results in death, is life-threatening, requires hospitalisation or prolongation of existing hospitalisation, results in disability/incapacity.
From first visit (Month 20) up to study conclusion (Month 50)
Number of Subjects Reported With Any Potential Immune-mediated Disease (pIMD)
Time Frame: From first visit (Month 20) up to study conclusion (Month 50)
pIMD's are a subset of Adverse Events that include autoimmune diseases and other inflammatory and/or neurologic disorders of interest which may or may not have an autoimmune aetiology.
