Title: A Multicentre, Randomized, Double-blind, Placebo-controlled, Parallel-group Study Of Oral Cp-690,550 As An Induction Therapy In Subjects With Moderate To Severe Ulcerative Colitis.
Brief Summary: This study is designed to evaluate the efficacy and safety of tofacitinib (CP-690,550) in patients with moderate to severe ulcerative colitis who have failed or be intolerant to one of following treatments for ulcerative colitis: oral steroids, azathiopurine/6-mercaptopurine, or anti-TNF-alpha therapy.


Options:
A: Inclusion Criteria:

* Participants who received all study agent administrations and completed the Week 6 Mayo score evaluation in induction study C0524T16 (NCT00488774) or C0524T17 (NCT00487539)
* Participants who completed the Week 0 visit for this maintenance study C0524T18 (NCT00488631) on the same day as the Week 6 visit of the induction study C0524T16 (NCT00488774) or C0524T17 (NCT00487539)

Exclusion Criteria:

* Participants who increased the dose of their concomitant (given at the same time) UC medications since Week 0 of induction study C0524T16 (NCT00488774) or C0524T17 (NCT00487539)
* Participants who initiated a concomitant UC medication since Week 0 of an induction study C0524T16 (NCT00488774) or C0524T17 (NCT00487539)
* Participants who had a partial or total colectomy (surgery to remove part or all of the colon) or an ostomy (surgical construction of an artificial opening (stoma) for external fistulization of a duct or vessel by insertion of a tube with or without a supportive stent) since Week 0 of an induction study C0524T16 (NCT00488774) or C0524T17 (NCT00487539)
* Participants with signs or symptoms of latent or active granulomatous infection (including TB); a nontuberculous mycobacterial infection or opportunistic infection; or infection with HIV (Human Immunodeficiency Virus), hepatitis B, or hepatitis C
* Participants with signs and symptoms of any malignancy or suggestive of a possible lymphoproliferative disease (disorders characterized by proliferation of lymphoid tissue, general or unspecified)
B: Inclusion Criteria:

* Subject must be at least 18 years of age.
* Males and females with a documented diagnosis of UC at least 4 months prior to entry into the study.
* Subjects with moderately to severely active UC based on Mayo score criteria.
* Subjects must have failed or be intolerant of at least one of the following treatments for UC:

  * Corticosteroids (oral or intravenous).
  * Azathioprine or 6 mercaptopurine (6 MP).
  * Anti TNF therapy.

Exclusion Criteria:

* Presence of indeterminate colitis, microscopic colitis, ischemic colitis, infectious colitis, or clinical findings suggestive of Crohn's disease.
* Subjects with disease limited to distal 15 cm.
* Subjects without previous treatment for UC (ie, treatment naïve).
* Subjects displaying clinical signs of fulminant colitis or toxic megacolon.
C: Inclusion Criteria:

* Has a clinical diagnosis of Ulcerative Colitis (UC) at least 3 months before Screening
* Has moderately to severely active UC, defined as a Baseline (Week 0) Mayo score of 6 to 12, including a Screening endoscopy subscore of the Mayo score greater than or equal to (\>=) 2 as determined by a central reading of the video endoscopy
* Have failed biologic therapy, that is, have received treatment with 1 or more tumour necrosis factor (TNF) antagonists or vedolizumab at a dose approved for the treatment of UC, and have a documented history of failure to respond to or tolerate such treatment; OR Be naïve to biologic therapy (TNF antagonists or vedolizumab) or have received biologic therapy but have not demonstrated a history of failure to respond to, or tolerate, a biologic therapy and have a prior or current UC medication history that includes at least 1 of the following: a. Inadequate response to or failure to tolerate current treatment with oral corticosteroids or immunomodulators (6-mercaptopurine \[6-MP\] or azathioprine \[AZA\]) OR b. History of failure to respond to, or tolerate, at least 1 of the following therapies: oral or IV corticosteroids or immunomodulators (6-MP or AZA) OR c. History of corticosteroid dependence (that is, an inability to successfully taper corticosteroids without a return of the symptoms of UC)
* Before the first administration of study agent, the following conditions must be met: vedolizumab must have been discontinued for at least 4 months and anti-tumor necrosis factors (TNFs) for at least 8 weeks

Exclusion Criteria:

* Has severe extensive colitis and is at imminent risk of colectomy
* Has UC limited to the rectum only or to \< 20 centimeters (cm) of the colon
* Presence of a stoma or history of a fistula
* Participants with history of extensive colonic resection (for example, less than 30 cm of colon remaining) that would prevent adequate evaluation of the effect of study agent on clinical disease activity
* Participants with history of colonic mucosal dysplasia. Participants will not be excluded from the study because of a pathology finding of "indefinite dysplasia with reactive atypia''
D: Inclusion Criteria:

* Subjects who met study entry criteria and completed 8-week induction treatment from Study A3921094 or A3921095
* Subjects who achieved clinical response in Study A3921094 or A3921095
* Women of childbearing potential must test negative for pregnancy prior to study enrollment
* Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures
* Evidence of a personally signed and dated informed consent document(s) indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the study.

Exclusion Criteria:

* Subjects who had major protocol violation (as determined by the Sponsor) in Study A3921094 or A3921095
* Presence of indeterminate colitis, microscopic colitis, ischemic colitis, infectious colitis, or clinical findings suggestive of Crohn's disease
* Subjects who have had surgery for UC or in the opinion of the investigator, are likely to require surgery for UC during the study period.
