Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals diagnosed with probable Alzheimer's Disease dementia who exhibit symptoms of agitation and meet specific cognitive assessment criteria.

Probably not a fit

Patients with forms of dementia other than Alzheimer's or those with severe cognitive impairment may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to assess the efficacy and safety of ONO-2020 in patients experiencing agitation associated with Alzheimer's Disease dementia. The study will involve administering ONO-2020 or a placebo to eligible participants, who must have a confirmed diagnosis of Alzheimer's and meet specific criteria related to their cognitive function and agitation symptoms. The trial will take place in Japan, focusing on hospitalized patients to ensure close monitoring throughout the treatment period.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce agitation in Alzheimer's patients, improving their quality of life.

How similar studies have gone: While there have been studies on agitation in Alzheimer's patients, the specific use of ONO-2020 represents a novel approach that has not been extensively tested.
