- Healthy male and/or female (non-childbearing potential) subjects between the ages of
18 and 55 years, inclusive (Healthy is defined as no clinically relevant abnormalities
identified by a detailed medical history, full physical examination, including blood

Show details

- A known sensitivity or previous intolerance to Dimebon or warfarin.

- Evidence or history of clinically significant hematological, renal, endocrine,
pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or
allergic (including drug allergies, but excluding untreated, asymptomatic, seasonal

Official Title  ICMJE A Phase 1, Randomized, Open-Label, Two-Way Crossover Study To Evaluate The Steady-State Effect Of Dimebon (PF 01913539) On The Single-Dose Pharmacokinetics And Pharmacodynamics Of Warfarin In Healthy Subjects
Brief SummaryThis study will evaluate the potential drug-drug interaction of Dimebon with the FDA-recommended CYP2C9 substrate warfarin in healthy subjects. Conformance with the guidance includes general study design using a randomized, open label, single-dose warfarin, steady-state Dimebon, 2-sequence, 2-treatment, 2-period crossover design with a minimum 7-day washout period between treatments.
