Merck & Co Inc (NYSE:MRK) suffered a rare setback as the US regulator rejected its application for a heart disease safety reference to be included with its diabetes best seller Januvia.
Merck wanted to highlight that a major trial involving the best seller drug indicated no heart problems for patients with type 2 diabetes.
This would have differentiated it from rivals known to have cardiovascular risks, such as Astrazeneca’s (LON:AZN) Onglyza.
Merck, though, received a Complete Response Letter from the US Food and Drug Administration on the use of Sitagliptin, the generic treatment for type 2 diabetes.
A complete response letter from the FDA means a drug will not be approved in its current form.
The pharma giant said it is reviewing the letter and will discuss its next steps with the FDA.
Shares eased 0.5% to US$62.95.
