MHRA requests further information on Cilansetron, Solvay ‘s proposed treatment for irritable bowel syndrome with diarrhea predominance (D-IBS)

Solvay Pharmaceuticals announced today that the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) has completed its review of cilansetron, a novel drug for the treatment of irritable bowel syndrome with diarrhea predominance (D-IBS) in both men and women.  The agency has concluded that it is unable to grant a marketing authorization without further clinical trials.  Solvay Pharmaceuticals is examining its priorities and will discuss future steps with the MHRA and other experts for this product in Europe.

About D-IBS
On average, IBS affects more than 11% of the EU population, with total annual direct costs of some £45 million in the UK alone. The common symptoms of D-IBS are diarrhea, abdominal pain/discomfort, and fecal urgency. IBS has a significant, negative impact on the quality of life for the many men and women who suffer from this condition, causing lost days off work and interfering as well with home-based, social and leisure activities.
