CERE-110 in Subjects With Mild to Moderate Alzheimer's Disease

A Phase I, Dose-Escalating Study to Assess the Safety and Tolerability of CERE-110 [Adeno-Associated Virus (AAV)-Based Vector-Mediated Delivery of Beta-Nerve Growth Factor (NGF)] in Subjects With Mild to Moderate Alzheimer's Disease

This is a Phase I clinical study to assess the safety, tolerability and biologic activity of in vivo AAV-mediated delivery of CERE-110. Up to 12 subjects will receive open label CERE-110 in dose-escalating fashion. All subjects will receive bilateral, stereotactic injections of CERE-110 for a total of four (Dose A and B) and six (Dose C) injections to target the basal forebrain region of the brain containing the nucleus basalis of Meynert (NBM). All study participants will be observed for a 24-month period and then followed annually.

• A Hamilton Depression Scale score of ≤ 12 on a 17-item scale and no history of major depressive episode within the last 2 years
• A score of < 15 on the Beck Depression Inventory
• Adequate visual and auditory acuity to allow neuropsychological testing
• Good health with no clinically significant medical or psychological conditions
• An MRI of the head at screen that is negative for evidence of infection, tumor, infarction or other focal (e.g., subdural hematoma) or generalized lesions(e.g., v hydrocephalus) and without clinical symptoms suggestive of intervening neurological disease
• Normal serum B12, thyroid function tests, and negative syphilis antibody test
• The informed consent document must be signed by both:

a competent and willing subject, and a surrogate identified by the participant, or a legally authorized power of attorney for Health Care, or a family member

Exclusion Criteria:
