News Summary: Roche probed for not reporting side effects of cancer, other drugs

SERIOUS CHARGE: Europe's top drug regulator is taking action against pharmaceutical giant Roche for allegedly failing to properly report the side effects of 19 drugs being used by U.S. patients. The regulator added there was no evidence that users of Roche's drugs were at risk.

POTENTIAL PENALTY: If Roche is found to have violated its reporting requirements, it could be fined up to 5 per cent of its sales in the European Union from the preceding year.

RANGE OF TREATMENTS: Eight of the drugs involved are used for the treatment of cancer, including the blockbuster Avastin. The flu drug Tamiflu was also included in the list.
