WILEX starts first oral Phase I study with MEK inhibitor WX-554
Munich, 15 September 2011. WILEX AG (ISIN DE0006614720 / WL6 / Frankfurt Stock Exchange) announced today the start of another Phase I trial with the small-molecule MEK inhibitor WX-554. The study is being conducted in healthy volunteers at a single site in Germany. The trial aims to determine safety, pharmacokinetic and pharmacodynamic properties of various single doses of the orally administered MEK inhibitor. Studies in cancer patients are expected to commence early next year.
The oral Phase I programme follows the successfully completed Phase I study with an intravenous formulation and will therefore also deliver an estimate of the bioavailability of the drug candidate.
The German Federal Institute for Drugs and Medical Devices (BfArM) approved this Phase I trial with the WX-554 in August 2011. WILEX expects study data in the first quarter of 2012.
The small-molecule MEK inhibitor is one of five oncology preclinical programmes obtained under the strategic alliance agreed with UCB in January 2009 and is being clinically developed by WILEX. Mitogen activated protein kinase (MEK) has been shown to play a central role in signal transduction. The MEK signalling pathway is over expressed in more than 30% of cancers, resulting in uncontrolled cell growth and proliferation. The first Phase I trial was successfully completed in the summer of 2010. The 25 volunteers in the dose escalation trial safely tolerated the intravenously administered WX-554.
