Biocitech Park, Paris (France), July 8th, 2010 - Endotis Pharma, the biopharmaceutical company
dedicated to the discovery and development of small-glyco drugs for applications in thrombosis and
oncology, announced that Phase I clinical trial results for EP217609 will be presented on July 8th at the
21st International Congress on Thrombosis (ICT) in Milan, Italy.
EP217609 is a first-in-class synthetic, parenteral anticoagulant which can be neutralized by a specific
antidote, avidin. EP217609 has a dual mechanism of action, which combines direct free and clot-bound
thrombin inhibition and indirect factor Xa inhibition.
In this first Phase I study, EP217609 was well tolerated in 24 healthy subjects exposed to single,
ascending doses. As expected, administration of EP217609 resulted in dose-dependent increases in
standard and specific coagulation tests and, a decrease in thrombin generation. EP217609
pharmacodynamic and pharmacokinetic profiles were predictable, with low inter-subject variability.
Eric Neuhart, MD, Head of Clinical Research and Development at Endotis Pharma commented:
“EP217609 and its specific antidote avidin are being developed in patients undergoing cardiac surgery.
These drugs could represent the first alternative to unfractionated heparin and its antidote protamine
which, despite their known limitations and side effects, have been used for more than 50 years during
cardiopulmonary bypass and extracorporeal circulation. Following positive results of two separate first-
in-man studies with EP217609, and avidin2, Endotis has initiated an additional Phase I study for
assessing EP217609 neutralization by avidin in healthy subjects.” Dr Eric Neuhart added: “Along with
ongoing preclinical pharmacology studies3, these Phase I clinical studies with EP217609 and avidin
represent key steps towards developing the two drugs in high-risk patients undergoing cardiac surgery.
Endotis’ strategy is to develop breakthrough drugs for clinical indications with high unmet medical
