What happened

  • Pharmacosmos complained that Vifor’s promotion of Ferinject (ferric carboxymaltose) showed a pattern of misleading and disparaging claims about competitor product Monofer (iron isomaltoside), particularly on safety.
  • Pharmacosmos said there were no head-to-head comparative safety/efficacy studies between Monofer and Ferinject, yet HCP feedback suggested Vifor reps implied Monofer had more adverse reactions.
  • Pharmacosmos cited six anecdotal examples (UK and Ireland) but stated these were provided to show an overall pattern rather than as individual, specific allegations.
  • A key piece of evidence was a medical information email sent to a specialist nurse enclosing the Dutch pharmacovigilance Lareb report. The email stated the report had not mentioned any specific safety concerns with Ferinject—this was untrue (the report included 7 hypersensitivity/anaphylactic reaction reports for Ferinject).
  • The Panel and Appeal Board focused heavily on Vifor’s internal/promotional materials, including:
    • Intravenous Iron Differentiator tool designed to be used proactively in accounts “threatened” by switching to Monofer or that had switched to Monofer, including slides comparing side-effects/contraindications.
    • SPC Comparator tool used to directly compare Ferinject and Monofer SPC sections in a promotional context, with insufficient guidance on appropriate use.
    • Briefings that highlighted Grant et al (a local audit of 40 Monofer patients) and the Lareb report, without adequate context or clear instructions limiting use.
⚖️

Outcome

  • Breach found: Clause 8.1 (disparagement).
  • Breach found: Clause 7.2 (misleading information).
  • Vifor appealed; the Appeal Board upheld both breaches and the appeal was unsuccessful.
