April 26 (Reuters) - Swiss drugmaker Roche said first-quarter sales dropped 7% on falling demand for its COVID-19 therapies and diagnostics kits.

Quarterly group revenue fell to 15.3 billion Swiss francs ($17.2 billion), the company reported on Wednesday, beating market expectations of 14.8 billion francs.
