More than 50% of the 160 patients have been treated since end of May 2010. The Phase IIb trial is a double-blind, randomized, parallel group study examining three doses of Remimazolam compared with midazolam in 160 patients undergoing a colonoscopy. The patients receive either one of three different doses of Remimazolam or Midazolam followed by 'top-ups' (i.e. multiple doses) as required to maintain an adequate sedation level to undergo a standard colonoscopy procedure. The study is being conducted in multiple sites in the U.S. It is designed to evaluate the safety of Remimazolam and the success of the sedation, the time to peak sedation, time to full recovery and discharge, in comparison to the gold-standard agent, midazolam. PAION expects to report results towards the end of 2010. Based on the successful Phase Ib and IIa studies, this Phase IIb study of Remimazolam will further refine the optimal dose regimen before moving into Phase III trials. 'We have been able to recruit patients faster than expected and therefore will deliver results possibly towards the end of 2010. Our collaborators and our team have done a great job in exceeding our own expectations,' commented Wolfgang Söhngen, CEO of PAION. 'These data are expected to be the triggering signal in the partnering process.' ### About Remimazolam (CNS 7056) Remimazolam is an innovative short-acting general anaesthetic/sedative. Sedatives are used, for example, in endoscopic procedures such as colonoscopies. After intravenous administration Remimazolam rapidly induces the desired sedation. Importantly, this sedative effect quickly disappears. This rapid offset of the effect of the substance is due to its metabolism by tissue esterase enzymes that are widely distributed throughout the body. Remimazolam is being developed as a sedative agent for day case procedures (procedural sedation) as well as for the induction and maintenance of anaesthesia. It could also be used as a sedative for patients on ventilation in the Intensive Care Unit (ICU). PAION is exploring partnering opportunities for the territories outside Japan, where the compound is partnered to Ono Pharmaceuticals in order to be able to initiate the development of Remimazolam in other indications as early as possible. As recently published, the INN (International Nonproprietary Name) for CNS 7056 recommended by the World Health Organisation is Remimazolam.
