This study examines CERE-110, a gene therapy that uses an adeno-associated virus to deliver nerve growth factor (NGF) to the brain, in people with mild to moderate Alzheimer's disease. It enrolled patients whose diagnosis was confirmed by NINCDS/ADRDA criteria and who were stable on standard treatments. The research was conducted in Phase 1 and has been completed.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
Inclusion Criteria: * Alzheimer's disease as determined by NINCDS/ADRDA criteria. * Score of ≤ 4 on a modified Hachinski Ischemia Scale * Mini-Mental State Exam (MMSE) score in the range of 16 to 28, inclusive * No significant neurological or medical abnormalities contraindicating surgery, MRI/PET imaging or study participation * Subjects stable on standard-of-care medications (i.e., acetylcholinesterase inhibitors) for Alzheimer's disease for 3 months prior to entry * 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: * History of cancer within the last five years, except superficial basal or squamous cell skin cancer or cervical carcinoma in situ * History of alcohol abuse or dependence within the last two years * Liver serum transaminases (AST and/or ALT) \> 5 times the upper limit of normal; total and/or direct bilirubin \> 1.5 mg/dL, hemoglobin \< 9mg/dL; PT and PTT \> 2 times the upper limit of normal; creatinine clearance \< 30 mL/min; positive serology for HBV or HCV; absolute neutrophil count \< 1,500 cells/mm3 and a platelet count \< 100,000/mm3 * Any significant systemic illness, unstable or severe medical condition(s) that could put the subject at risk during the study, interfere with outcome measures or affect compliance with the protocol procedures * Centrally active beta-blockers, anti-Parkinsonian medications, psychostimulants, antipsychotics, neuroleptics, or narcotic analgesics, long-acting benzodiazepines or barbiturates, hypertensive agents with a CNS effect, short-acting anxiolytics or sedative hypnotics more frequently than two times per week within 14 days of screening, herbal products for Alzheimer's disease, antidepressants with significant cholinergic side effects (e.g., tricyclics), initiation or change in dose of standard treatment for Alzheimer's disease * Other medication with significant cholinergic or anticholinergic side effects * Warfarin (coumadin), nonsteroidal anti-inflammatory drugs, aspirin, Prozac, or Ginkgo biloba within 14 days of surgery * Subjects who have received investigational agents or been exposed to investigational devices for 30 days prior to enrollment * Subjects with a history of receiving gene transfer products of any kind * Subjects who cannot undergo MRI or PET screening
