Frequently asked questions about Meningococcal vaccine 134612

What is Meningococcal vaccine 134612 used for?

Meningococcal vaccine 134612 is an investigational vaccine being developed for the prevention of meningococcal infections. It is currently in Phase 2 clinical development and has been studied in healthy adolescents and adults. The vaccine is designed to elicit an immune response against meningococcal disease, though it is not yet approved for commercial use.

Who makes Meningococcal vaccine 134612?

Meningococcal vaccine 134612 is being developed by GSK plc, a global biopharmaceutical company. GSK is conducting clinical trials to evaluate the vaccine's safety and immunogenicity in healthy adolescents and adults. The company's ticker symbol is GSK.

What phase is Meningococcal vaccine 134612 in?

Meningococcal vaccine 134612 is in Phase 2 clinical development. It is an investigational vaccine and has not been approved by regulatory authorities. Two Phase 2 trials have been completed, with a total of 919 participants enrolled across studies conducted in Denmark and the United States.

What clinical trials is Meningococcal vaccine 134612 in?

Meningococcal vaccine 134612 has been evaluated in two completed Phase 2 clinical trials. NCT00390143 assessed persistence of immune response up to 3.5 years in 46 adolescents and adults in Denmark. NCT00454909 compared the vaccine to Menactra in 873 healthy adolescents and adults aged 10-25 years in the United States.

How does Meningococcal vaccine 134612 work?

Meningococcal vaccine 134612 is designed to stimulate the immune system to produce antibodies against Neisseria meningitidis, the bacteria that cause meningococcal disease. By inducing a protective immune response, the vaccine aims to prevent infections caused by this pathogen. The exact mechanism involves the presentation of meningococcal antigens to the immune system.
