Summary
This study will evaluate what effect renal dysfunction has on a drug that has an intravenous (CP-70,429) and an oral form (PF-03709270).
Eligibility Criteria
Inclusion Criteria
Subjects must meet one of the following renal function categories:
- Normal renal function (CLcr >80 mL/min).
- Mild renal impairment (CLcr >50 and 30 and <50 mL/min).
- Severe renal impairment (CLcr <30 mL/min).
Exclusion Criteria
Women who are pregnant or nursing or women who are of childbearing potential. History of clinically significant allergies, including seasonal allergies, and especially drug hypersensitivity including known allergies to components of the study drug formulation, penicillin, carbapenems and/or cephalosporin antibiotics (eg, amoxicillin, amoxicillin/clavulanate, ampicillin, cefadroxil, cephalexin, cefaclor and cefixime).
Subjects should not have evidence of a history of the following:
- normal renal function: clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurological or allergic disease.
- renal impairment: any clinically significant (hepatic, cardiac or pulmonary or subjects with acute nephritic syndrome) diseases (except diabetes). Stable co-morbid disease where it is unlikely that the disease and medication will alter the outcome of the study will be allowed.
