NCT02982642

Brief Summary

This study is a 52-weeks, multicenter, randomized, double-blind, placebo controlled, parallel trial which will be carried out in 15 centers around China. The study population includes amnestic mild cognitive impairment patients (planned a total of 240) aged 55-85 in both gender. Participants will be randomly allocated to 1612 capsules (1.14g per time, 3 times per day) or placebo for a 52-weeks double-blind treatment period. The primary outcome measure is change from baseline in the Alzheimer's Disease Assessment Scale- Cognition Subscale (ADAS-cog) and rate of conversion to dementia. The secondary outcomes are changes from baseline in the Mini-Mental State Examination (MMSE), Delayed Story Recall test (DSR), Alzheimer's Disease Cooperative Study/Activities of Daily Living scale adapted for MCI patients (ADCS/MCI/ADL24). Safety is being assessed by observing side effects and adverse reaction during the entire treatment period. Statistical analysis will be conducted according to per-protocol population and intend-to-treat population and the safety will be analyzed in safety set.

Outcome Measures

Primary Outcomes (2)

  • Change in cognitive scores: Alzheimer Disease Assessment Scale-cognitive subscale (ADAS-cog)

    Cognition will accessed with the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog), at baseline (day 1 clinic visit) and week 4, week 12, week 24 ,week 36 , week 48 and week 52.

    52 weeks

  • Change from baseline to end of double-blind treatment of rate of dementia conversion from mild cognitive impairment

    The rate of demention conversion will accessed from baselin at week 0 and week 4, week 12, week 24 ,week 36 , week 48 and week 52.

    52 weeks
