Safety and Immunogenicity Study of GSK's Clostridium Difficile Vaccine 2904545A When Administered in Healthy Adults Aged 18-45 Years and 50-70 Years

Clostridium Infections Clinical Trial

Official title:
A Phase I, Single-center, Randomized, Observer-blind, Placebo-controlled Study to Evaluate Safety, Reactogenicity and Immunogenicity of GSK's Clostridium Difficile Investigational Vaccine Based on the F2 Antigen With or Without AS01B Adjuvant, When Administered Intramuscularly According to a 0, 1-month Schedule to Healthy Adults Aged Between 18-45 Years and Between 50-70 Years, Followed by an Additional Dose Administered in a Partial Blind Manner Within an Interval of Approximately 15 Months After Dose 2, in a Subcohort of Subjects Aged 50-70 Years

Status Completed

Clinical Trial Summary

The purpose of this study is to generate safety, reactogenicity (assessment of any expected or unexpected side effect of the vaccine) and immunogenicity (ability to induce an immune response) data for the development of a candidate Clostridium difficile (C. difficile) vaccine that would protect against primary cases of Clostridium difficile infection (CDI) and CDI recurrence. Clostridium difficile infection is a major cause of gastrointestinal illness with approximately 500,000 infections and the leading cause of gastroenteritis associated death with 29,000 deaths annually in the United States of America (USA). The emergence of extremely infectious varieties/types of C. difficile has contributed to increase the number and severity of CDI cases. In recent years, some countries (United Kingdom) have implemented hospital hygiene and other measures which resulted in significant reductions in the number of cases. The burden is, however, expected to remain significant until vaccination is available.
