What happened

  • An anonymous complainant challenged AstraZeneca’s UK promotional website for Trixeo Aerosphere (www.trixeo.co.uk) and a downloadable Trixeo formulary pack.
  • Allegations included: public access (no HCP gating), non-proprietary name too small, prescribing information (PI) not easily accessible on mobile, misleading efficacy/safety claims (relative vs absolute risk; “prevent exacerbations”; “Protection you can count on”; “A well-established safety profile”), use of capitalisation, and a dragon image implying special properties.
  • AstraZeneca said the site was intended for UK health professionals with an HCP declaration pop-up and footer notice; it took the site down after the complaint to address mobile-display issues.
  • AstraZeneca acknowledged technical/certification failures affecting mobile view: (1) generic name difficult to read on mobile, (2) PI required two clicks on mobile, and (3) the mobile view had not been certified.
  • The website and formulary pack referenced comparator arms in ETHOS/KRONOS using non-proprietary names for budesonide/formoterol (Symbicort) and glycopyrrolate/formoterol (Bevespi); PI for those products was not provided.
⚖️

Outcome

  • No breach found for alleged promotion to the public (complainant did not establish, on the balance of probabilities, that the website constituted promotion to the public).
  • Breach for non-proprietary name readability on mobile devices.
  • Breach for PI not being accessible via a single click on mobile devices.
  • Breach for failure to certify the website for mobile viewing (final form differed from certified view).
  • Breach for missing PI for AstraZeneca comparator products (Bevespi Aerosphere and Symbicort Turbohaler) mentioned on the website and in the downloadable formulary pack.
  • No breach for the challenged claims/images (including “Unleash protection from exacerbations with Trixeo”, relative/absolute risk presentation, “You can prevent exacerbations”, “Protection you can count on”, “A well-established safety profile”, capitalisation/font, and the dragon image).
  • No breach of Clause 2 (Panel did not consider the circumstances warranted that level of censure).
