Title: A3921024 Lymphocyte Substudy.
Date and version: as for A3921024 long-term open-label follow-up study.
Primary:
To evaluate the changes in the absolute lymphocyte counts (ALCs) and lymphocyte subset counts (LSCs) over time with long-term tofacitinib treatment.
Secondary:
To evaluate the correlation of tofacitinib safety events (eg, infections with ALCs or LSCs)
Exploratory:
To evaluate the reversibility of LSCs and ALCs after temporary discontinuation of tofacitinib and rechallenge; to evaluate the utility of monitoring LCSs in addition to ALCs mitigate the risk of infections. |

| E.3 | Principal inclusion criteria |
Patients who enroll from a qualifying study within a 14 day window must meet Inclusion Criteria 1, 2, 4, 6, 7 and 8 below and must continue to meet safety eligibility criteria of their qualifying study for continued participation. Patients who enroll after the 14 day window must meet all Inclusion Criteria including Inclusion Criteria 3 and 5 to be eligible for enrollment into the trial. 1. Evidence of a personally signed and dated informed consent document indicating that the patient (or a legally acceptable representative) has been informed of all pertinent aspects of the trial. 2. Patient must be at least the legally recognized age of consent or provide assent in writing along with a consent signed by their legally recognized representative. 3. In the opinion of the investigator the patient must have sufficient evidence of RA disease activity to warrant use of CP-690,550 as a DMARD. 4. Patients must have previously completed participation in a qualifying study of CP 690,550 for treatment of RA or have required earlier discontinuation of treatment in a qualifying study for reasons other than CP 690,550 related serious adverse events with the approval of the Pfizer study clinician. 5. No evidence of active or latent or inadequately treated infection with Mycobacterium tuberculosis (TB) as defined by all of the following: • A negative QuantiFERON Gold®TM In-Tube test performed within the 3 months prior to screening. A negative PPD test can be substituted for the QuantiFERON TB Gold In Tube test only if the central laboratory is unable to perform the test or cannot determine the results to be positive or negative and the Pfizer Medical Monitor approves it, on a case-by-case basis; A chest radiograph taken within the 3 months prior to screening without changes suggestive of active TB infection; No history of either untreated or inadequately treated latent or active TB infection. If a patient has previously received an adequate course of therapy for either latent (9 months of isoniazid in a locale where rates of primary multi drug resistant TB infection are <5% or an acceptable alternative regimen) or active (acceptable multi drug regimen) TB infection, neither a PPD test nor a QuantiFERON Gold®TM test need be obtained, but a chest radiograph must still be obtained if not done so within the prior 3 months. A patient who is currently being treated for latent TB infection can only be enrolled with confirmation of current incidence rates of multi drug resistant TB infection, documentation of an adequate treatment regimen, and prior approval of the Sponsor. In Ireland, patients currently being treated for either latent or active TB infection cannot be enrolled. 6. The patient has discontinued disallowed concomitant medications for the required time prior to the first dose of study drug, as defined in Appendix A, and is taking only those concomitant medications in doses and frequency allowed by the protocol. 7. If the patient is a sexually active woman of childbearing potential, she must test negative for pregnancy prior to enrollment in this study. Sexually active women of childbearing potential are required to use adequate contraceptive methods during participation in this study. Men who are on background therapy and whose partners are women of childbearing potential will be required to follow the local label requirements for their background medications (including background DMARDs). Further description of the requirements and a list of contraceptives considered effective and acceptable for use in this study will be found in Lifestyle Guidelines 8. Patients who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other trial procedures.
