Alzheimer's Disease With Vascular Pathology Clinical Trial
Official title:
A Phase 2a Study Evaluating the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of CY6463 When Administered to Participants With Alzheimer's Disease and Vascular Pathology
This study is being conducted to test the safety, tolerability, and pharmacokinetics of the investigational drug CY6463 compared with placebo in individuals who are aged 60 years or older and have Alzheimer's disease (AD) along with common cardiovascular risk factors.
CY6463 is an investigational drug being developed as a symptomatic and potentially disease-modifying therapy for Alzheimer's disease (AD) and other serious central nervous system disorders. As a soluble guanylate cyclase (sGC) stimulator, CY6463 can cross the blood-brain barrier and boosts the activity of the nitric oxide-soluble guanylate cyclase-cyclic guanosine monophosphate (NO-sGC-cGMP) pathway. This signaling pathway is important in many aspects of brain health, including in the control of blood flow in the brain, how brain cells use energy, and how those cells communicate with one another. Impairment of this pathway is a critical part of the origin of many neurodegenerative diseases that can cause a loss of brain function including memory and decision-making abilities. There are clear links between disrupted NO signaling and impaired brain function in patients with AD and vascular pathology (ADv). ("Vascular pathology" refers to abnormalities of the blood vessels that are more likely to occur when a person has cardiovascular risk factors like high blood pressure, diabetes, and/or obesity.) It is hypothesized that CY6463 may help patients with ADv maintain or recover some of their original cognitive function. In this study, participants will be randomized to receive approximately 87 sequential days (~3 months) of study drug (CY6463 or placebo) once daily (QD) and will complete 7 scheduled site visits over the course of the study, from Screening through Follow up. ;
