+++ End of Ad hoc release +++

MESUPRON® (INN: Upamostat) is a proprietary, first-in-class urokinase-type plasminogen activator (uPA) inhibitor administered by oral capsule. The uPA system has been shown to play a key role in tumor cell growth, invasion and the metastasis process. High uPA levels are associated with poor prognosis in various solid tumor cancers, such as pancreatic, gastric, breast and prostate cancers. MESUPRON® presents a promising new non-cytotoxic approach to cancer therapy with several potential mechanisms of action to inhibit both tumor metastasis and growth. MESUPRON® has completed several Phase I studies and two Phase II proof of concept studies, the first Phase II study in locally advanced non-metastatic pancreatic cancer and the second in metastatic breast cancer, which have established its safety and tolerability profile. The Phase II studies with MESUPRON® in both indications suggested activity as measured by both tumor response rate and overall survival of patients when administered in combination with first-line chemotherapeutic agents.
