Merck says US rejects its MS drug

(AFP) – German pharmaceutical group Merck KgaA said Wednesday that the US Food and Drug Administration (FDA) has refused to approve use of its multiple sclerosis treatment Cladribine.

The FDA declined to approve the drug "in its present form" and asked Merck to "provide an improved understanding of the safety risks and the overall benefit-risk profile," either through additional analyses or studies.
