Inclusion criteria
The factors, or reasons, that allow a person to participate in a clinical study.
Show details

- 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
pressure and pulse rate measurement, 12 lead ECG and clinical laboratory tests).

- Prothrombin time (PT)/INR, and partial thromboplastin time (PTT).

- Plasma Protein C and Protein S activity (functional) within the normal reference
range.

Exclusion criteria
The factors, or reasons, that prevent a person from participating in a clinical study.
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
allergies at time of dosing) disease or clinical findings at Screening.

- Subjects receiving warfarin for treatment of active thromboembolic events (ie,
pulmonary embolism, deep vein thrombosis), as well as subjects anticoagulated with
prosthetic heart valves.

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
This 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.
