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).

Condition Intervention Phase
Drug: CP-70,429 and PF-03709270
Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Endpoint Classification: Pharmacokinetics Study
Intervention Model: Crossover Assignment
Masking: Open Label
Official Title: An Open-Label, 2-Way Crossover Study To Investigate The Pharmacokinetics, Safety And Tolerability Of IV CP-70429 And Oral PF-03709270 In Subjects With Varying Degrees Of Renal Impairment And Normal Renal Function

Further study details as provided by Pfizer:

Primary Outcome Measures:
  • The primary pharmacokinetic endpoints to be evaluated for CP 70429 include Cmax, Tmax, AUClast, AUCinf, and CLr. [ Time Frame: Day 1-3 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Pharmacokinetics of CP-70429 and PF-03709270 metabolites. [ Time Frame: Day 1-3 ] [ Designated as safety issue: No ]
  • Safety and tolerability will be assessed by adverse events, vital signs, 12 lead ECGs, physical examinations, laboratory safety tests (blood and urine). [ Time Frame: Screening -Day 4 ] [ Designated as safety issue: Yes ]
  • Secondary pharmacokinetic endpoints will include t1/2, time above MIC1.0 (duration of plasma concentrations of CP 70429 exceeding 1.0 μg/mL) and time above MIC0.5 (duration of plasma concentrations of CP 70429 exceeding 0.5 μg/mL). [ Time Frame: Day 1-3 ] [ Designated as safety issue: No ]

Enrollment: 29
Study Start Date: November 2008
Study Completion Date: March 2010
Primary Completion Date: March 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: IV CP-70,429 and cross over to PF-03709270 Drug: CP-70,429 and PF-03709270
Study Periods 1 and 2 will be separated by a minimum of 14 days. In Period 1, subjects will receive a single dose of CP-70429 (800 mg given as a 1.5 hour intravenous infusion), while in Period 2, subjects will receive a single oral dose of PF-03709270 (1000 mg).
Other Name: CP-70,429 - sulopenem

Detailed Description:
To evaluate the pharmacokinetics and safety.

Ages Eligible for Study:   18 Years to 85 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes

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 <80 mL/min).
  • Moderate renal impairment (CLcr >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.
