A 6-Month Study Of CP-690,550 Versus Tacrolimus In Kidney Transplant Patients
A 6-Month, Phase 2, Multicenter, Randomized, Open-Label, Comparative Study Of 2 Dose Levels Of CP-690,550 Administered Concomitantly With IL-2 Receptor Antagonist Induction Therapy, Mycophenolate Mofetil And Corticosteroids Versus A Tacrolimus-Based Immunosuppressive Regimen For The Prevention Of Allograft Rejection In De Novo Renal Allograft Recipients

Brief Summary
This Phase 2 study was designed to evaluate the safety and efficacy of 2 dose levels of CP-690,550 (15 mg twice daily and 30 mg twice) against tacrolimus, in combination with basiliximab induction, mycophenolate mofetil and corticosteroids, in kidney transplant patients. Stage 1 was to randomize approximately 54 subjects. After all Stage 1 subjects had completed 6 months of treatment, Stage 2 was to randomize an additional 195 subjects to the same treatment groups.

Outcome Measures
Primary Outcomes (2)
Number of Participants With First Biopsy Proven Acute Rejection (BPAR) at Month 6
BPAR categorized as acute rejection as interpreted by the central blinded pathologist according to the Banff 97 working classification.
Baseline up to Month 6
Glomerular Filtration Rate (GFR) by Nankivell Equation at Month 6
GFR: index of kidney function described the flow rate of filtered fluid through the kidney. GFR was measured directly or estimated using established formulas. GFR was calculated by creatinine clearance (CLcr) using Nankivell equation. CLcr by Nankivell equation= (6.7 per serum creatinine) plus (0.25\*body weight) minus (0.5\*serum urea) minus (100 per square height) plus (35 for male/25 for female). A normal GFR is \>90 milliliter/minute (mL/min), although children and older people usually have a lower GFR. Lower values indicated poor kidney function. A GFR \<15 mL/min indicated kidney failure.
