Conjugated meningococcal ACWY-TT is a vaccine being developed for the prevention of meningococcal infections. It is intended to protect against meningococcal disease, which is caused by Neisseria meningitidis bacteria. The vaccine is in Phase 2 clinical development and has been studied in children.
Conjugated meningococcal ACWY-TT targets ESR2 and ESR1 as an agonist. These molecular targets are associated with the vaccine's mechanism of action. The vaccine is designed to induce an immune response against meningococcal serogroups A, C, W, and Y.
Conjugated meningococcal ACWY-TT is being developed by GSK plc, which trades under the ticker symbol GSK. GSK is a global pharmaceutical company involved in the research and development of vaccines and medicines.
Conjugated meningococcal ACWY-TT is in Phase 2 clinical development. It is an investigational vaccine and has not been approved by the FDA. The Phase 2 trials have been completed, and the vaccine remains under clinical evaluation.
Conjugated meningococcal ACWY-TT has been studied in two completed Phase 2 trials: NCT00196976 and NCT00126984. NCT00196976 evaluated safety and immunogenicity in children aged 12-14 months and 3-5 years in Austria and Greece. NCT00126984 assessed four formulations in children in Austria and Germany.
Yes, conjugated meningococcal ACWY-TT is also known as conjugated meningococcal ACWY-TT (vaccine). The parenthetical addition clarifies that it is a vaccine. Both names refer to the same investigational product developed by GSK.
