Background and aim: Vascular dementia (VaD) is the second most common cause of dementia and currently there is scarcity of therapies for VaD. We aimed to investigate the efficacy and safety of MLC601 in the treatment of VaD.
Methods: In this multicenter, pilot, randomized, double-blind trial, 82 patients with VaD according to DSM-5 criteria received MLC601 or placebo capsules three times a day for 2 years. The primary efficacy end-point was evaluated by comparing Mini-Mental State Examination (MMSE) and Alzheimer’s Disease Assessment Scale-cognitive subscale (ADAS-cog) score between the two groups over 2 years of study. Safety was also assessed by recording adverse events and abnormal laboratory results.
Results: Eighty-one patients completed the study and were included in the analysis. One patient was lost to follow-up in the placebo group. After 2 years, mean (±SD) changes in the MMSE score were –3.71 (±4.50) for MLC601 group and –9.33 (±4.80) for placebo group. ADAS-cog score showed (±SD) changes of 7.34 (±9.55) and 19.00 (±11.28) for MLC601 and placebo group, respectively. Repeated measures analyses showed that both MMSE and ADAS-cog scores were significantly better in the treatment group at 24 months (p<0.001). Ten (24.39%) patients reported predominantly transient gastrointestinal adverse events in MLC601 group. No patient left the study due to adverse events. There were no clinically significant abnormalities on laboratory tests.
Conclusion: Patients treated with MLC601 over the 2 years showed dramatically better cognitive outcome compared with those treated with placebo. MLC601 was devoid of any serious adverse events and was well-tolerated.
