研究概览

简要总结

This study will evaluate four different modified release formulation to estimate the amount of dimebon available to the body relative to the current dimebon formulation that is given three times a day. The results of this study will help inform and guide further formulation development efforts with the ultimate goal of reducing dose frequency to once-a-day or twice-a-day.
