Trial Outcomes & Findings for Safety, Efficacy and Dose Titration of Sodium Oligo-mannurarate Capsule on Mild to Moderate Alzheimer's Disease (NCT NCT01453569)

NCT ID: NCT01453569

Last Updated: 2015-01-27

Results Overview

Alzheimer's Disease Assessment Scale-cognitive Subscale(ADAS-cog)/12 is the most popular cognitive testing instrument used in clinical trials. It consists of 12 tasks measuring the disturbances of memory, language, praxis, attention and other cognitive abilities which are often referred to as the core symptoms of AD. The total score ranges 0-75, the higher score indicates more severity of the disease. Change after 24 wks treatment was calculated by the week 24 minus week 0 (baseline), and a negative change represents an improvement.

PRIMARY outcome

Timeframe: 24 weeks

Population: 85, 84, 86 patients were enrolled, and 2, 8 and 3 subjects were excluded from FAS in placebo, 600 mg and 900 mg group respectively. So the case No. ananlysed were 83, 76, 83 for placebo, 600 mg and 900 mg group respectively.

Clinician's Interview-Based Impression of Change Plus(CIBIC-plus) is widely used in antidementia drug trials. It comprises Likert scales for disease severity and changes, and written accounts summarizing semistructured interviews evaluating behavior, cognition, and function. The results classified as 7 degrades as: Markedly improved, Moderately improved, Minimally improved, No change, Minimally worse, Moderately worse, and Markedly worse.

Alzheimer's Disease Cooperative Study/Activities of Daily (ADCS-ADL) is a scale assessed the daily activties of AD patients after interviewed the caregiver. The scale mainly assess the eating, walking, writing, bathing and reading, et al of the subject. The total score ranges 0-78, the higher score indicate improvement in daily activities. Change after 24 wks treatment was calculated by the week 24 minus week 0 (baseline), and a positive change represents an improvement.

Neuropsychiatric Inventory (NPI) is a scale to obtain information on the presence of psychopathology in patient with brain disorders. The NPI was developed for application to patients with AD and other dementias, but it may be useful in the assessment of behavioral changes in other conditions. Twelve behavioral areas included in the NPI will be assessed in this trial: delusions, hallucinations, agitation/aggression, depression/dysphoria, anxiety and elation/euphoria, et al. The total score ranges 0 to 120, the higher score indicates worse state of the AD patient. Change after 24wks treatmnt was calculated by the week 24 minus week 0 (baseline), and a negative change represents an improvement.
