A health professional complained about four webpages within GSK’s UK HCP promotional site (GSKPro) for Jemperli (dostarlimab).
They alleged the mobile versions differed from desktop (text colour/placement and a mobile “Product menu” navigation label) and therefore required separate certification for mobile.
They also alleged a homepage claim was misleading/unqualified: “JEMPERLI + CP offers a manageable safety profile consistent with the known profiles of its individual components after 2 years of follow-up”, arguing serious AEs can require permanent discontinuation (black triangle product).
GSK said desktop and mobile views were reviewed and certified within the same job; differences were formatting/navigation for legibility and user experience, not substantive content changes.
GSK argued “manageable” was supportable in oncology context and consistent with SmPC guidance that management can include discontinuation, plus trial/publication support.
