Study Description

Brief Summary:

Purpose: The purpose of this study is to examine the efficacy and safety of Fufangdanshen Tablets in patients with mild to moderate vascular dementia (VaD).

Condition or disease	Intervention/treatment	Phase
Vascular Dementia	Drug: Fufangdanshen Tablets; Drug: Placebo	Phase 2

Detailed Description:

This multicenter, double-blind, placebo-controlled study will evaluate the safety and effectiveness of Fufangdanshen Tablets in patients with vascular dementia. All patients will initially receive placebo for a 2 weeks period and then will receive Fufangdanshen Tablets or placebo for 6 months. The primary measures of effectiveness include the change from baseline to the end of treatment in the ADAS-cog/11 score (Alzheimer's Disease Assessment Scale: sum of 11 cognitive items) and the CIBIC-plus score (Clinician's Interview Based Impression of Change - Plus Caregiver Input). Additional measures of effectiveness include the change from baseline to the end of the treatment in the MMSE score (Mini-mental State Examination), the ADL (Ability of Daily Living) score. Safety evaluations (incidence of adverse events, electrocardiograms (ECGs), physical examinations, laboratory tests) will be performed throughout the study. Patients who complete the double-blind portion of the study will be followed up 12 weeks. Effectiveness will be assessed at 12 weeks, 24weeks and 36 weeks. Safety evaluations (incidence of adverse events, ECGs, physical examinations, laboratory tests) will be performed at 12 weeks, 24weeks and 36 weeks of the study. The study hypothesis is that Fufangdanshen Tablets will be effective in the treatment of patients with vascular dementia and will be well tolerated. Double-blind: Fufangdanshen Tablets: 3 tablets per time, 3 times per day, and placebo : 3 tablets per time, 3 times per day. The placebo has similar smile and appearance as the Fufangdanshen Tablets.

Outcome Measures

Primary Outcome Measures :

1. Change from baseline to end of double-blind treatment Clinician's Interview Based Impression of Change - Plus Caregiver Input; Alzheimer Disease Assessment Scale-cognitive subscale [ Time Frame: 24 weeks ]
   Global cognition was assessed with the CIBIC-plus, at baseline (day 1 clinic visit) and at 12-week intervals thereafter until week 24.
2. Change in cognitive scores: Alzheimer Disease Assessment Scale-cognitive. subscale (ADAS-cog) [ Time Frame: 24 weeks ]
   Cognition was assessed with the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog), at baseline (day 1 clinic visit) and at 12-week intervals thereafter until week 24.

Secondary Outcome Measures :

1. Change in functional scores: Activities of Daily Living (ADL). [ Time Frame: 24 weeks ]
   Functional ability was evaluated with the ADL was evaluated at baseline (day 1 clinic visit), at the mid-study (week 12), and at the endpoint of treatment (week 24).
2. Change from baseline to the end of double-blind treatment in Mini-mental state examination (MMSE) scores [ Time Frame: 24 weeks ]
   Change in global cognition:Mini-mental state examination at baseline (day 1 clinic visit) and at 12-week intervals thereafter until week 24.
