Impact of Aortic Valve Calcification on Functional Valve Area and Cardiac Structure and Function in a Phase 2 Trial of Ataciguat (AHA 2025) - P2 | "ATA may have other favorable effects on ventricular, valvular, and/or vascular pathophysiology relevant to patients with CAVS.Hypothesis:We hypothesized that slowing the rate of AVC deposition is associated with improvements in valvular compliance and in measures of cardiac structure and function.A phase 2 study randomized patients with moderate CAVS 1:1 to receive ATA 200 mg/day or placebo for up to 12 months (NCT02481258). These data suggest that slowing the rate of AVC deposition with ATA may result in improvements in CO through improved myocardial function and valvular compliance. Larger controlled trials are needed to assess such favorable myocardial/valvular effects that may help to preserve functional capacity and slow progression to HF."

Discovery of the Soluble Guanylate Cyclase Activator Runcaciguat (BAY 1101042). (PubMed, J Med Chem) - "The first generation of sGC activators like cinaciguat or ataciguat exhibited limitations and were discontinued. This program resulted in the discovery of the oral sGC activator runcaciguat (compound 45, BAY 1101042). Runcaciguat is currently investigated in clinical phase 2 studies for the treatment of patients with chronic kidney disease and nonproliferative diabetic retinopathy."

Soluble guanylate cyclase stimulators and their potential use: a patent review. (PubMed, Expert Opin Ther Pat) - "After the first generation of sGC stimulators like riociguat or lificiguat, new compound classes with different physicochemical and kinetic profiles were identified, like the sGC stimulators vericiguat or praliciguat...Expert Opinion: With the recent advancements reported in the patent literature, sGC stimulators might be differentiated due to tissue selectivity or route of application although exhibiting the same molecular mode of action. The indication space of these compounds is potentially very broad and multiple indications in cardiovascular diseases and beyond are under investigation."
