FOR IMMEDIATE RELEASE Cardiorentis AG and Roche Announce Collaboration to Establish Therapeutic Impact of Ularitide Z UG and ROTKREUZ, Switzerland – October 16, 2014 -- Cardiorentis AG, a privately held biopharmaceutical company, today announced a collaboration with Roche to establish the therapeutic efficacy and safety of Ularitide, the Company’s investigational drug for acute heart failure (AHF). Under the terms of the collaboration, Cardiorentis will incorporate Roche’s advanced in vitro diagnostic tests into its TRUE-AHF Phase III Study to characterize the pharmacological properties of Ularitide, evaluate its benefit-risk profile and the appropriate clinical application in patients. “Roche is the world leader in in vitro diagnostics and has been consistently recognized for its breakthrough medical innovations for the treatment of cardiovascular diseases. This collaboration allows us to incorporate the most advanced biomarkers into our TRUE-AHF trial and we are hopeful it will result in proven outcome benefits for patients with acute heart failure,” stated Johannes Holzmeister, M.D. Chief Executive Officer and Chief Medical Officer, Cardiorentis. “Our in vitro diagnostic tests provide critical clinical information addressing doctor’s needs to guide the patient’s treatment regime. Incorporating these tests into the TRUEAHF trial will enable us to further validate their clinical value in a large patient population but more importantly advance the development of new treatment options for acute heart failure,” added Prof. Christian Zaugg, Head of Disease Area Strategy at Roche Professional Diagnostics. The TRUE-AHF Phase III trial was initiated in August 2012. It is led by the international principal investigator Milton Packer, M.D., University Texas, Southwestern Medical Center in Dallas, Texas and includes over 200 centers across the U.S., Europe, Canada and Latin America. TRUE-AHF is an event driven trial, which may enroll up to 4,000 patients with acute heart failure. There are two co-primary endpoints. The first is a composite endpoint for acute heart failure which assesses a patient’s symptoms and persistence or worsening of heart failure within the first 48 hours after treatment initiation. The second co-primary endpoint is cardiovascular mortality. About Ularitide Ularitide is a natriuretic peptide in Phase III development as an intravenous infusion treatment for acute heart failure (AHF), limited by United States law to investigational use only. Ularitide is the chemically synthesized form of urodilatin - a human, natriuretic peptide that is produced in the kidneys and induces excretion of sodium into the urine (natriuresis) and increased urine production (diuresis) to regulate fluid balance and sodium homeostasis. Ularitide induces natriuresis and diuresis by binding to specific natriuretic peptide receptors (NPR-A, NPR-B and other natriuretic peptide receptors), thereby increasing intracellular cyclic guanosine monophosphate (cGMP) helping to relax smooth muscle tissues, leading to vasodilation and in creased blood flow. About AHF Heart failure is a growing problem worldwide. More than 26 million people around the world are affected.[1],[2] AHF can be defined as the sudden or gradual onset of the signs or symptoms of heart failure resulting in a need for urgent therapy or hospitalisation. In 2011, there were nearly 3 million hospital admissions with heart failure as ang J, Mensah GA, Croft JB, Keenan NL. Heart failure-related hospitalization in the U.S.,1979 to 2004.

It is a life- threatening condition which requires immediate medical attention. Signs and symptoms of AHF include extreme fatigue and shortness of breath, worsening kidney function, severe swelling, sudden weight gain and a dis tended jugular vein along the side of the neck.
