  • The EMEA coordinates the evaluation and supervision of medicinal products throughout the European Union.
  • The Agency brings together the scientific resources of the 25 EU Member States in a network of the national competent authorities.
the emea
The EMEA
  • A network of some 3,500 European experts underpins the scientific work of the EMEA and its committees.
  • Began its activities in 1995, when the European system for authorizing medicinal products was introduced
  • Is primarily involved in the Centralised Procedure (CP).

  • April 2003 – aggravation of Myasthenia gravis
variations of product information
Variations of product information
  • October 2003 –
    • ADR section updated with info concerning hepatic ADRs, anaphylactic reactions and visual disorders
    • Driving section updated with information concerning visual disorders which may impair the ability to drive
variations of product information19
Variations of product information
  • November 2004 – monitoring of PT-INR while patients are receiving telithromycin and anticoagulants simulataneously
  • July 2005 –transient loss of consciousness added to ADR section and accordingly also a driving warning was introduced
variations of product information20
Variations of product information
  • February 2006 – warnings regarding severe hepatitis and liver failure which may occur with short latency and in most cases were reversible. Patient should be informed of signs and symptoms
  • September 2006 – contraindication in patients with previous liver reactions during exposure to telithromycin + hepatic fatalities
assessment of hepatic safety january 2006
Assessment of hepatic safetyJanuary 2006
  • The PhVWP and the CHMP considered that:
    • characteristics of serious hepatic reactions were not well described in the product information
    • that the short latency to onset of these reactions was of concern in patients treated in primary care
    • an update of product information be requested
hepatic safety january 2006 contd
Hepatic safety January 2006 contd.
  • further assessment of available data needed
  • a Risk Management Plan on hepatic safety be requested

Accordingly, the product information was updated and a List of Question was sent to the MAH

assessment hepatic safety may 2006 follow up measure 26
Assessment hepatic safety, May 2006.(Follow-up measure 26).
  • Most of the available data on hepatic safety was considered consistent with the current labelling.
  • No risk factors could be identified except a tendency for patients with CAP to be at higher risk of liver reactions
assessment hepatic safety may 2006
Assessment hepatic safety, May 2006.
  • The RMP was considered satisfactory and the presented protocol for an epi-study of severe hepatic events in the USA should be updated.
  • The risk-benefit of Ketek was still considered favourable
assessment hepatic safety may 200625
Assessment hepatic safety, May 2006.
  • The assessment of available data on hepatic safety of Ketek in the EU member states was continued.
renewal of the marketing authorization
Renewal of the Marketing Authorization
  • The application for renewal of the MA was assessed in parallell with the re-assessment of the hepatic safety

renewal of the marketing authorization27
Renewal of the Marketing Authorization
  • Considering the increased awareness of safety issues, especially the hepatic safety, the CHMP was of the opinion that one additional five-year renewal on the basis of pharmacovigilance ground was required.

assessment of cases of serious hepatic adrs reported in the eu september 200629
Assessment of cases of serious hepatic ADRs reported in the EU (September 2006)
  • The reporting rate or serious hepatic reactions was estimated to be 4-10 cases per million courses
  • These data were in line with the current product information and did not alter the conclusions drawn by the CHMP in June 2006.
assessment of cases of serious hepatic adrs reported in the eu september 200630
Assessment of cases of serious hepatic ADRs reported in the EU (September 2006)

  • A full Risk Management Plan was requested (according to the new legislation)
additional regulatory measures in the eu
Additional regulatory measures in the EU
