Cyclerion Therapeutics to Present Preclinical Data on its Clinical-Stage sGC Stimulators for Neurodegenerative and Cardiometabolic Diseases at the 9th International Conference on cGMP
– Series of preclinical studies provide further rationale for study of IW-6463 as a potential treatment for neurodegenerative diseases –
– Preclinical data provide insights into praliciguat’s metabolic effects and mechanism of action –
One presentation will discuss the results of a series of preclinical studies on IW-6463, Cyclerion’s central nervous system (CNS)-penetrant sGC stimulator designed to address serious neurodegenerative diseases, showing an association between treatment with IW-6463 and decreased markers of neuroinflammation, enhanced blood flow in brain regions associated with cognition, improved dendritic spine density and structure and restored cognitive performance. Two presentations will address preclinical studies with praliciguat, Cyclerion’s systemic sGC stimulator currently in clinical development as a potential treatment for diabetic nephropathy and for heart failure with preserved ejection fraction (HFpEF). The first preclinical study demonstrated an association between treatment with praliciguat and improved insulin sensitivity, lower triglycerides and increased fat oxidation. The second study provided insights into praliciguat’s mechanism of action by characterizing the nature of its high affinity binding to sGC.
“We are excited to present preclinical data supporting the potential of sGC stimulation to treat neurodegenerative and cardiometabolic diseases, both of which are growing medical concerns facing our aging global population,” said
Cyclerion is focused on unlocking the full therapeutic potential of the nitric oxide-cyclic guanosine monophosphate (cGMP) signaling pathway, a clinically validated pathway with potential for therapeutic applications in a wide range of cardiovascular, metabolic, inflammatory, fibrotic and neurological diseases. sGC is a key node in this pathway, and Cyclerion’s targeted sGC stimulators are designed to enhance pathway signaling in the tissues of greatest relevance to the diseases each is intended to treat.
Cyclerion’s Oral Presentations:
- Cyclerion will present the results of a series of preclinical studies that evaluated the pharmacological effects of IW-6463 and informed the initiation of a Phase 1 clinical study to evaluate the safety, tolerability, pharmacodynamics and pharmacokinetics of IW-6463 in single- and multiple-ascending dose studies in healthy human volunteers.

IW-6463 is a central nervous system (CNS)-penetrant sGC stimulator that Cyclerion believes is the first and only sGC stimulator designed to address neurodegenerative diseases. Nitric oxide is a fundamental neurotransmitter with demonstrated impact on memory and cognition. In serious CNS diseases associated with nitric oxide deficiency, IW-6463 may amplify endogenous nitric oxide signaling to restore neuronal health and function. More broadly, in neurodegenerative diseases of varying etiologies, IW-6463 has the potential to enhance cognition and combat neurodegeneration via the neuroprotective and neurofunctional benefits of nitric oxide signaling.
In preclinical studies, IW-6463 demonstrated significant exposure in the CNS. Treatment with IW-6463 was associated with increases in cerebral blood flow, reductions in markers of neuroinflammation, increased neuroprotection and enhanced cognition across a variety of preclinical models. IW-6463 is currently being evaluated in a Phase 1 clinical study in healthy human volunteers.
Praliciguat, a once-daily, orally available systemic sGC stimulator in development for the treatment of cardiometabolic diseases, is being studied in patients with diabetic nephropathy and in patients with heart failure with preserved ejection fraction (HFpEF). Both conditions are growing global epidemics with few or no approved treatment options. Diabetic nephropathy affects an estimated eight million Americans and 20 to 40 percent of all diabetic patients worldwide. It is the leading cause of end-stage renal disease. Currently available products do not treat the underlying pathophysiology of the disease or fully address the needs of this patient population. HFpEF affects an estimated three million Americans and 40 to 70 percent of heart failure patients worldwide. It is a highly symptomatic condition with high rates of morbidity and mortality that can cause insufficient delivery of oxygen to the tissues, fluid in the lungs and edema of the extremities, causing patients to be short of breath and have compromised exercise tolerance. There are no approved therapies to treat HFpEF.
Currently in Phase 2 development for diabetic nephropathy and for HFpEF, praliciguat has the potential to address the underlying causes of these devastating diseases by improving nitric oxide signaling, which may improve vascular and metabolic function and decrease the inflammatory and fibrotic consequences associated with these diseases.
