Chase's lead compound, CPC-201, is a patent-protected combination of the most commonly prescribed acetylcholinesterase inhibitor (AChEI), donepezil[Aricept], and the peripherally acting cholinergic blocker, solifenacin. AChEIs have been shown to improve cognition in Alzheimer's disease patients. Currently approved AChEIs are only modestly effective due to dose-limiting side effects, including diarrhea, nausea and vomiting.
In Phase 2 clinical trials, 29 out of 33 patients (88%) reached 40 mg/day of donepezil (maximum dose allowed), without experiencing dose-limiting adverse events.,, Chase's next-generation formulations offer the possibility of greater and more tolerable dosing, and may provide the potential for significantly improved cognition and function in Alzheimer's disease patients.
Chase Pharmaceuticals recently completed an End of Phase 2 meeting with the Food and Drug Administration (FDA). Based on feedback from the FDA, Allergan intends to advance CPC-201 into a single Phase 3 registration study in 2017.
