A Phase 1, Non-Randomized, Open-Label, Single-Dose Study To Evaluate The Pharmacokinetics, Safety, And Tolerability Of Dimebon [PF 01913539] In Subjects With Severely-Impaired And Normal Renal Function
December 29, 2009 updated by: Pfizer
This study is to compare the pharmacokinetics of Dimebon in subjects with severe renal impairment to subjects with normal renal function after oral administration of a single oral 20-mg dose of Dimebon.
This study is also to assess the safety and tolerability of a single oral 20-mg dose of Dimebon in subjects with severe renal impairment and subjects with normal renal function.

Description
Inclusion Criteria:
- Male and/or female subjects between the ages of 18 and 75 years, inclusive
- For severe renal impairment group, subjects with creatinine clearance of less than 30 mL/min, but not yet on dialysis and in good general health commensurate with the population with chronic renal disease; however, subjects with type 1 and 2 diabetes that are reasonably controlled and who do not have a predisposition to severe hypoglycemia can both be included.
- For normal renal function group, healthy subjects with creatinine clearance of greater than 80mL/min and demographically comparable to subjects with impaired renal function
Exclusion Criteria:
- Pregnant or nursing women; women of childbearing potential (WOCBP) who are unwilling or unable to use an acceptable method of contraception as outlined in the protocol from at least 14 days prior to the first dose of study medication.
- For normal renal function group, use of prescription or non-prescription drugs, vitamins, or dietary supplements within 7 days of 5 half-lives (whichever is longer) prior to the first dose of study medication.
Herbal supplements and hormone replacement therapy must be discontinued 28 days prior to the first dose of study medication. Acetaminophen at doses of ≤ 2 grams/day is permitted.
- For renal impairment group, a known history of clinically significant coronary heart disease, cerebrovascular disease or peripheral vascular disease and/or an event/intervention during the past 6 months. Systemic therapy with CYP3A or CYP2D6 inhibitors within 7 days or 5 halflives (whichever is longer) prior to the first dose of trial medication.
