Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Change in measured glomerular filtration rate (as determined by iohexol serum clearance) at the end of Period 1 from baseline. [ Time Frame: End of Period 1, approximately Day 43 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Change in measured glomerular filtration rate (mGFR) at the end of Period 2 from baseline. [ Time Frame: End of Period 2, approximately Day 72 ] [ Designated as safety issue: Yes ]
  • Change in mGFR at the end of Period 2 from the end of Period 1. [ Time Frame: End of Period 2, approximately Day 29 ] [ Designated as safety issue: Yes ]
  • Change in estimated glomerular filtration rate (eGFR) from baseline to the end of Period 1. [ Time Frame: End of Period 1, approximately Day 43 ] [ Designated as safety issue: Yes ]
  • Change in eGFR from baseline to the end of Period 2. [ Time Frame: End of Period 2, approximately Day 72 ] [ Designated as safety issue: Yes ]
  • Change in serum creatinine from baseline to the end of Period 1. [ Time Frame: End of Period 1, approximately Day 43 ] [ Designated as safety issue: Yes ]
  • Change in serum creatinine from baseline to the end of Period 2. [ Time Frame: End of Period 2, approximately Day 72 ] [ Designated as safety issue: Yes ]
  • American College of Rheumatology (ACR) 20/50/70 and Disease Activity Score 28 joint count and using C-Reactive Protein (DAS28 [CRP]) at end of Period 1. [ Time Frame: End of Period 1, approximately Day 43 ] [ Designated as safety issue: No ]
  • ACR20/50/70 and DAS28 (CRP) at end of Period 2. [ Time Frame: End of Period 2, approximately Day 72 ] [ Designated as safety issue: No ]

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • The patient must meet the American College of Rheumatology (ACR) classification criteria for the diagnosis of rheumatoid arthritis by satisfying at least four of the seven criteria.
  • The patient must have active disease at both Screening and predose on Day 1 of Period 1.
  • Patient must have had an inadequate response to at least one disease-modifying antirheumatic drug (DMARD), non-biologic or biologic, due to ineffectiveness or intolerance.

Exclusion Criteria:

  • Pregnant or lactating women
  • Serious medical conditions that would make treatment with CP-690,550 potentially unsafe.
  • A patient who has a history of asthma, multiple allergies or severe allergy (eg, anaphylaxis) to any substance. In particular, a history of allergy to iodine, povidone-iodine, iohexol or other iodinated contrast media.
