Posiphen® Dose-Finding, Biomarker Study in Early Alzheimer's and Parkinson's Patients

Summary

Annovis is conducting a clinical study to investigate Posiphen in patients with Early Alzheimer's Disease (AD) and Early Parkinson's Disease (PD). Investigators are looking to recruit 68 patients in two parts of the study. In Part one of the study Investigators will recruit 14 AD and 14 PD patients who will either receive placebo (an inert pill which looks like the study drug) or the study drug Posiphen, both taken daily. In Part two of the study Investigators will recruit 40 PD patients who will receive different strengths of the study drug Posiphen taken daily. Patients will be required to come to the site for 3 face to face visits and have 4 phone calls, tests include but are not limited to, blood and CSF (spinal fluid) sampling, cognitive assessments, clinical examinations and laboratory safety tests. Primarily the Investigators are looking for the safety and tolerability of Posiphen, although Investigators will also evaluate the activity of Posiphen by a number of different biomarkers measuring pathway and target engagements.
