Wilex developed WX-UK1 as a specific inhibitor of human trypsin-2, human trypsin-3 and urokinase-plasminogen activator. WX-UK1 participated in phase I clinical trial in combination with capecitabine in advanced malignancies to determine the safety, tolerability, maximum tolerated dose, pharmacokinetics, and pharmacodynamics. However, in April 2014, the clinical development of this drug was discontinued, as part of a company restructure.
