About this trial
Previous studies found that some NMDA-enhancing agents were able to improve cognitive function of patients with early-phase dementia. In addition, several drugs with antioxidant properties have been tested in clinical trials for the treatment of dementia too. Whether combined treatment of an NMDA-enhancing agent and a drug with antioxidant property can be better than an NMDA-enhancing agent alone deserves study.

Trial outcomes
Primary outcomes
Change from baseline in the Alzheimer's disease assessment scale - cognitive subscale at week 8, 16 and 24
Alzheimer's disease assessment scale-cognitive subscale consists of 11 tasks. Its scores range from 0 (best) to 70 (worst).
Secondary outcomes
Change from baseline in Clinician's Interview-Based Impression of Change plus Caregiver Input score at week 8, 16 and 24
Clinician's Interview-Based Impression of Change plus Caregiver Input score is a global assessment of change based on a comprehensive, semi-structured interview which includes caregiver-supplied information. It is a 7-point rating scale ranging from 1-7, where 1 represents markedly improved; 4, no change; and 7, markedly worse.
Change from baseline in Mini-Mental Status examination score at week 8, 16 and 24
Change from baseline in Mini-Mental Status examination score at week 8, 16 and 24
Change from baseline in Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) score at week 8, 16 and 24
Clinical Dementia Rating Scale (CDR) is a global assessment tool that yields global and Sum of Boxes scores (SB). Compared to the global CDR score, the CDR-SB score provides better utility in tracking changes in dementia severity.
Change from baseline in Alzheimer's disease Cooperative Study scale for ADL in MCI (ADCS-MCI-ADL) score at week 8, 16 and 24
ADCS-MCI-ADL appears to be a suitable instrument for evaluating activities of daily living in mild cognitive impairment. Its scores range from 0 (worst) to 78 (best).
