Cilansetron. Solvay

Cilansetron is a 5-HT3 antagonist tinder development by Solvay Pharmaceuticals as a potential treatment for irritable bowel syndrome (IBS). The compound targets non-constipated men and women with IBS. Cilansetron is being evaluated in phase III trials, but up to now, only scarce information has been made available and most publications have appeared in abstract form only. In July 2001, it was reported that regulatory submissions were expected in 2003 [416185]. Also in July 2001, after discussion with the FDA, Solvay initiated a revised phase III program in diarrhea-predominant IBS and signed a five-year 'preferred-provider' clinical services agreement with Quintiles Transnational to conduct the trial. At this time, Solvay was also seeking marketing partners for cilansetron [416185]. By October 1999, Solvay was treating cilansetron as one of its main priorities, as it represented a novel class of compound [342434]. Solvay has predicted peak sales of euro 100 m to euro 1000 m [420654].
