GSK’s Shingrix proven effective in immune-compromised patient populations

BY Michael Johnsen

GlaxoSmithKline on Wednesday announced that new data from a Phase III clinical study supports the safety and efficacy of Shingrix ((Zoster Vaccine Recombinant, Adjuvanted) in preventing shingles (herpes zoster) when given to adults 18 years and above shortly after undergoing autologous haematopoietic stem cell transplant (auHSCT).

“The immune systems of these stem cell transplant recipients is substantially weakened compared to the general older adult populations studied in other Shingrix efficacy trials,” Emmanuel Hanon, senior vice president and head of vaccines R&D for GSK said. “This puts them at much higher risk for viral diseases like shingles and, at the same time, makes developing an effective vaccine to help protect them more challenging. Today’s results, demonstrating the vaccine’s ability to help prevent shingles and its complications with just two doses, may provide a much-needed benefit to these patients considering the high incidence and burden of disease they face.”

GSK is evaluating these results together with those of other Phase III studies in immune-compromised patient populations. All these data will be shared and discussed with regulatory as well as public health agencies with the objective of best informing health care providers on the use of Shingrix in those patients with greatest medical need.

Shingrix is a non-live, recombinant adjuvanted subunit vaccine given intramuscularly in two doses and is the first shingles vaccine to combine a non-live antigen, to trigger a targeted immune response, with a specifically designed adjuvant to generate a strong and sustained immune response.

Shingrix is now approved in Canada and U.S. for the prevention of herpes zoster in adults aged 50 years and above. Regulatory reviews are currently underway in the European Union, Australia and Japan.
