CPC-201 Experimental

Criteria

Inclusion Criteria:

Aged 50 - 79 years inclusive.
Meeting the diagnosis of probable Alzheimer's Disease
Of moderate severity (Mini-Mental Status Exam [MMSE] score 10 - 20 inclusive).
Patients must be in generally good health as indicated by their medical history and physical examination, vital signs, electrocardiogram (ECG), and standard laboratory tests.

Exclusion Criteria:

Women of child bearing potential.
History or presence of a seizure disorder.
History of peptic ulcer disease, urinary or gastric retention; asthma or obstructive pulmonary disease.
History or presence of bladder outflow obstruction, gastrointestinal obstructive disorder or reduced GI motility, or narrow-angle glaucoma.
History or presence of gastrointestinal, hepatic, or renal disease, or other condition known to interfere with the absorption, distribution, metabolism or excretion of drugs.
History or presence of myasthenia.
Known hypersensitivity to donepezil, solifenacin or related drugs.
Any other clinically relevant acute or chronic diseases which could interfere with patients' safety during the trial, or expose them to undue risk, or which could interfere with study objectives.
Patients who have participated in another clinical trial with an investigational drug within previous 30 days.
