What happened

  • A UK-based doctor complained about an interaction at Theramex’s commercial booth at a gynaecological endocrinology congress in Italy (May 2024).
  • The complainant alleged the representative discussed endometriosis and ongoing trials, implied linzagolix (Yselty) would be licensed for endometriosis soon, and gave the impression it was readily available.
  • The complainant later understood linzagolix was not licensed for endometriosis and was not available for prescription in the UK and most European countries.
  • No hardcopy materials were provided; the complainant did not know the representative’s name and believed they were not a UK representative.
  • Theramex denied the allegations, said it could not identify the individual, and described pre-congress briefings/SOPs requiring booth conversations to stay within the licensed indication and unsolicited off-licence questions to be referred to medical via a medical information request process.
  • The Panel noted Yselty was licensed (uterine fibroids) at the time, but not licensed for endometriosis.
  • The Panel reviewed a promotional panel which stated the licensed indication and included “Non commercializzato in Italia - not marketed in Italy”.
