Rosiglitazone: a question mark about the safety

The European Medicines Agency (EMA) is reassessing the hypoglycemic medicines containing rosiglitazone used in the treatment of type 2 diabetes, following the publication of new studies on the cardiovascular risk associated with their use. The Committee for Medicinal Products for Human Use (CHMP) of the EMA, at its next plenary meeting (19-22 July 2010), will decide whether it is appropriate to withdraw, suspend or modify the marketing authorisation of these medicines.

The European Medicines Agency has started a review of the rosiglitazone-containing anti-diabetes medicines Avandia, Avandamet and Avaglim, to determine whether new data on the risk of cardiovascular problems have an impact on their benefit-risk profile.

The review by the Agency’s Committee for Medicinal Products for Human Use (CHMP) follows the recent publication of further studies on the cardiovascular safety of rosiglitazone.

Rosiglitazone on its own is authorised in the EU as Avandia, in combination with metformin as Avandamet and with glimepiride as Avaglim. At the time of their authorisation, these medicines were contra-indicated in patients with heart failure or a history of heart failure. Since then, the product information has been updated to include warnings and contra-indications on the use of these medicines in patients with heart problems.

In 2008, the CHMP concluded that on the basis of the available evidence and with the restrictions in place, rosiglitazone retained a small, if diminishing, place in diabetes type 2 therapy. The Committee is now assessing the new data and will be discussing the issue at its next plenary meeting of 19-22 July 2010. Once all relevant data on the benefits and the risks of rosiglitazone have been looked at, the CHMP will issue an opinion on whether the marketing authorisations for these medicines should be revoked, suspended or changed.
