What happened

  • A “concerned UK health professional” complained about GW Pharmaceuticals’ UK corporate website (gwpharm.co.uk).
  • GW was the marketing authorisation holder (MAH) of Sativex; in the UK, Sativex was promoted by Bayer (per GW).
  • GW had submitted a marketing authorisation application (MAA) to the EMA for Epidiolex (cannabidiol) for seizures associated with Lennox-Gastaut syndrome (LGS) and Dravet syndrome; other cannabinoid products were in development.
  • The complainant alleged the patients/caregivers section was not sufficiently delineated from the general public and there was no separate general public section.
  • The complainant alleged that the health professional section made claims for Sativex but did not include prescribing information.
  • The complainant alleged the “pipeline” section was “blatant pre-licence promotion” (including statements such as “highly promising data” and detailed information about Epidiolex and regulatory status).
  • Because an alleged breach of undertaking was raised, the Director took that aspect up (PMCPA responsibility for undertakings).
⚖️

Outcome

  • Breach found: Clause 3.1 (promotion of an unlicensed medicine), Clause 4.1 (prescribing information not provided in promotional material), Clause 4.6 (internet promotional material lacked clear, prominent statement as to where prescribing information can be found).
  • No breach found: Clauses 2, 3.2, 16.1, 26.1, 26.2, 28.1, 29.
  • The Panel did not consider the ruling in this case to be a breach of the undertaking given in Case AUTH/3014/1/18.
