GSK plc GSK announced positive topline results from a phase III study evaluating the co-administration of its two marketed vaccines — RSV vaccine Arexvy and shingles vaccine Shingrix — in older adults (aged 50 years and older).

(Reuters) -British drugmaker GSK said on Wednesday administration of its respiratory syncytial virus (RSV) vaccine and shingles shot together generated the same immune response in a late-stage trial as separate adminstration of the vaccines.

GSK plc (NYSE:GSK) released topline data from the phase 3 trial in adults 50 years and older evaluating the immunogenicity, reactogenicity and safety of Arexvy (Respiratory Syncytial Virus Vaccine) when co-administered with Shingrix (Zoster Vaccine).

If approved, the co-administration of Arexvy and Shingrix could provide a more convenient vaccination regimen for patients and potentially bolster GSK’s faltering sales for both vaccines.

In the study, co-administration of GSK's RSV vaccine Arexvy and shingles shot Shingrix elicited non-inferior immune responses compared with separate administration of the vaccines.

UK drugmaker GSK presented positive Phase III trial data at the European Geriatric Medicine Society Congress. The trial showed that co-administering Arexvy (RSV vaccine) and Shingrix (shingles vaccine) in adults 50+ produced a non-inferior immune response and was well tolerated.
