Brief Summary
This is a study that will follow transplant patients from Study A3921030 to monitor for long term safety, tolerability and efficacy for 5 additional years, except in Portugal where the study will follow transplant patients through Month 36 posttransplant. Patients will continue their study medications that were previously assigned.

Outcome Measures
Primary Outcomes (6)
Kaplan-Meier Analysis of Percentage of Participants With Clinically Significant Infection by Visit
Clinically significant infection was defined as the presence of documented infection confirmed by culture, biopsy, genomic, or serologic findings post-randomization and requiring hospitalization or parenteral anti-infective treatment, or otherwise deemed significant by the investigator. The 'Number' and 'Other Confidence Interval Level' columns represent cumulative proportions and 60% confidence intervals (CIs) as estimated from the fitted Kaplan-Meier curves for each treatment at scheduled visits.
Months 12, 15, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72
Percentage of Participants With Malignancies
All treatment-emergent malignancies in Study A3921050 were included as collected on the Malignancy Case Report Form page.
Months 12 through 72.
Least Squares Means of Measured Glomerular Filtration Rate (GFR) (Iohexol Serum Clearance in Milliliters Per Minute [mL/Min])
Glomerular filtration rate (GFR): an index of kidney function. GFR described the flow rate of filtered fluid through the kidney. GFR was calculated using iohexol serum clearance. For determination of iohexol serum clearance, iohexol was administered as an intravenous (IV) bolus over 5 minutes immediately after morning dosing of Tofacitinib or CsA on day of GFR evaluation. Blood samples for iohexol (3 millilitres \[mL\] each to provide a minimum of 1 mL serum) were collected into appropriately labeled tubes containing no additives at 120, 180, 240, and 300 minutes after the end of the iohexol IV bolus. A normal GFR is greater than (\>) 90 mL/min, although children and older people usually have a lower GFR. Lower values indicated poor kidney function. A GFR less than (\<) 15 mL/min indicated kidney failure.
Month 36
Percentage of Participants With Progression of Chronic Allograft Lesions at Month 36
Progression of chronic allograft lesions was defined as an increase in the Banff chronicity score (Banff-CS) in biopsy from the implantation (baseline) biopsy in a given participant. Banff-CS was the sum of the Banff scores for the 4 chronic basic lesions (allograft glomerulopathy \[cg\] + interstitial fibrosis \[ci\] + tubular atrophy \[ct\] + vascular intimal thickening \[cv\]). The Banff-CS ranged from 0-12, higher score indicated greater lesions and Month 36 Banff-CS greater than the implantation biopsy score indicated progression of lesions.
Month 36
Kaplan-Meier Analysis of Percentage of Participants With First Biopsy Proven Acute Rejection (BPAR) by Visit
BPAR was category acute rejection as interpreted by the central blinded pathologist according to the Banff 97 working classification. The 'Number' and 'Other Confidence Interval Level' columns represent cumulative proportions and 60% confidence intervals (CIs) as estimated from the fitted Kaplan-Meier curves for each treatment at scheduled visits.
Months 12, 15, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72
Kaplan-Meier Analysis of Percentage of Participants With Treated Clinical Acute Rejection by Visit
Treated clinical acute rejection was defined as an acute rejection episode that was diagnosed based on local biopsy readout and received anti-rejection treatment. The 'Number' and 'Other Confidence Interval Level' columns represent cumulative proportions and 60% confidence intervals (CIs) as estimated from the fitted Kaplan-Meier curves for each treatment at scheduled visits.
Months 12, 15, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72
Secondary Outcomes (22)
Kaplan-Meier Analysis of Percentage of Participants With Efficacy Failure by Visit
Months 12, 15, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72
Kaplan-Meier Analysis of Percentage of Participants With Combined Banff Rejection by Visit
Months 12, 15, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72
Kaplan-Meier Analysis of Percent of Participants With Graft Survival With Death Censored by Visit
Months 12, 15, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72
Kaplan-Meier Analysis of Percentage of Participants Surviving by Visit
Months 12, 15, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72
Percentage of Participants Discontinuing From the Study
Months 12 through 72.
