Orion withdraws US application for extending the indication of Stalevo®

Orion - Company announcement
ORION CORPORATION        STOCK EXCHANGE RELEASE      21 October 2009            AT 05.15 pm EET
Orion withdraws US application for extending the indication of Stalevo®
Orion Corporation has withdrawn the US application for extending the current US indication of its proprietary drug Stalevo® (levodopa, carbidopa and entacapone) to patients with early Parkinson's disease. The withdrawal is based upon Orion's assessment of findings from clinical studies with Stalevo, i.e. FIRST-STEP and STRIDE-PD, which indicate that Stalevo does not provide a consistent risk/benefit profile for the early Parkinson's disease patient population at the dosing regimen tested. In early March 2009, Orion withdrew the corresponding EU application.
In the USA, Stalevo is currently indicated to treat patients with idiopathic Parkinson's disease to substitute for immediate-release carbidopa/levodopa and entacapone previously administered as individual products and to replace immediate-release carbidopa/levodopa when certain patients experience the signs and symptoms of end-of-dose "wearing-off".
Previous stock exchange releases dealing with the above-mentioned studies and related actions have been published by Orion on 24 January 2008, 15 April 2008, 24 February 2009 and 6 March 2009. These releases are available on the Orion's homepage, address
