A Phase Ib Randomized, Placebo-controlled, Double-blinded Study Evaluating the Safety of Ataciguat (HMR1766) in Patients With Moderate Calcific Aortic Valve Stenosis
This study will determine whether Ataciguat (HMR1766) is well-tolerated in patients with
mild to moderate calcific aortic valve stenosis. The primary focus of these studies will be
on changes in blood pressure and orthostatic tolerance (i.e., ability to stand up without
passing out), and determining whether treatment with Ataciguat results in significant
reductions in blood pressure in this patient population.
