NCT06803823 · Phase 2 · RECRUITING
A Study of ONO-2020 in Patients With Agitation Associated With Alzheimer's Disease Dementia
This Phase 2 trial is testing an experimental drug called ONO-2020 against a placebo to see whether it reduces agitation in people already living with Alzheimer's dementia. Agitation — restlessness, aggression, combativeness — is one of the hardest symptoms for families and caregivers to manage. Phase 2 means researchers are still gathering evidence on whether it works and is safe; it is not approved or proven.
You may qualify if
- Diagnosis of probable AD according to the diagnostic criteria for AD dementia (NIA-AA 2011)
- Mini-Mental State Examination (MMSE) score ≥ 5 to ≤ 22 at the start of the treatment period
- Symptoms of agitation defined by the IPA from at least 14 days before the start of the screening period
- Neuropsychiatric Inventory-Nursing Home version (NPI-NH) Agitation/Aggression domain (NPI-NH-A/A) score ≥ 4 at the start of the treatment period.
- Patients who can participate in the study under hospitalization from 21 days before the start of the treatment period to throughout the treatment period
You're excluded if
- Diagnosis of dementia not due to AD or any other disorder with memory impairment, such as mixed dementia, vascular dementia, Lewy body dementia, dementia associated with Parkinson's disease, frontotemporal dementia, drug-induced dementia, dementia associated with human immunodeficiency virus (HIV) infection, traumatic brain injury, normal pressure hydrocephalus, or other non-AD dementia
- Any MRI or CT scan of the brain performed after the onset of dementia with findings consistent with clinically relevant CNS disease other than AD, such as vascular changes (eg, cortical cerebral infarction, multiple cerebral infarctions), space-occupying lesions (eg, tumors), or any other major structural brain disease
- Delirium within 30 days before the start of the screening period or a history of delirium
- At risk of suicide according to the Columbia-Suicide Severity Rating Scale (C-SSRS) (answers "yes" to Question 4 or 5 of the suicidal ideation section of the C-SSRS) or any suicide attempt within 6 months before the start of the screening period, or at serious risk of suicide in the opinion of the investigator or subinvestigator
