Descriptive Information
Brief Title  ICMJE A Study In Healthy Volunteers To Estimate The Pharmacokinetics Of Four Modified-Release Formulations Of Dimebon (Latrepirdine)
Official Title  ICMJE A Phase 1, Randomized, Open-Label, Single Dose Cross-Over Study In Healthy Volunteers To Estimate The Pharmacokinetics Of Four Modified-Release Formulations Of Dimebon (Latrepirdine)
Brief SummaryThis 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.
