Main Inclusion:
1. Subject must be able and willing to provide written informed consent and comply with the
requirements of this study protocol.;2. Male or female >= 18 and <= 75 years of age at the Baseline visit.;3. Subject with a diagnosis of UC for 90 days or greater prior to Baseline, confirmed by endoscopy (colonoscopy or flexible sigmoidoscopy) during the Screening Period, with exclusion of current infection, dysplasia and/or malignancy. Appropriate documentation of biopsy results consistent with the diagnosis of UC, in the assessment of the Investigator, must be available.;4. Active UC with a Mayo Score of 6 to 12 points and endoscopy subscore of 2 to 3 (confirmed by
central reader) despite concurrent treatment with at least one of the following oral corticosteroids or immunosuppressants as defined below:
- Subject taking oral corticosteroids, excluding budesonide or beclomethasone:
Oral corticosteroid dose must be <= 40 mg/day (prednisone or equivalent):
Dose > 10 and <= 40 mg/day: dose has been stable for at least 7 days prior to Baseline and the duration of the current steroid course has been at least 14 days prior to Baseline.
Dose <= 10 mg/day, dose has been stable for at least 10 days prior to Baseline and the duration of the current steroid course has been at least 14 days prior to Baseline.;- Subject taking oral budesonide: Dose must not exceed 9 mg/day:
Dose >= 6 mg/day, dose has been stable for at least 7 days prior to Baseline and the duration of the current steroid course has been at least 14 days prior to Baseline.
Dose < 6 mg/day, dose has been stable for at least 10 days prior to Baseline and the duration of the current steroid course has been at least 14 days prior to Baseline.;• Subject taking oral beclomethasone: dose must not exceed 5 mg/day;
* Dose has been stable for at least 7 days prior to Baseline and the duration of the current steroid course has been at least 14 days prior to Baseline.;or,
At least a consecutive 42-day course of azathioprine, 6-mercaptopurine (6-MP) or injectable
methotrexate (MTX) prior to Baseline, with a stable dose for at least 28 days prior to Baseline of
azathioprine >= 1.5 mg/kg/day or 6-MP >= 1 mg/kg/day (rounded to the nearest available tablet or half tablet formulation) or a documented 6-TGN level of at least 230 pmol/8 x 108 RBC to clarify a therapeutic level was achieved on the current dosing regimen or MTX >= 15 mg/week (Subcutaneous [SC]/Intramuscular [IM]), or a dose that is
the highest tolerated by the subject (e.g., due to leukopenia, elevated liver enzymes, nausea)
during that time.
Note: If a subject is taking (both an oral corticosteroid and an immunosuppressant listed above)BOTH of the drugs need to meet the above dosing and duration of use criteria. Oral MTX use is allowed during the study (at a stable dose for 28 days prior to Baseline), however prior or current use of oral MTX is not sufficient for inclusion into the study.
or,
Concurrent therapy with oral corticosteroids or immunosuppressants (azathioprine, 6-MP or
SC/IM MTX) is not required for subjects not currently taking these medications who were
previously treated during the past 1 year and have confirmed documentation of failure to
respond, or were previously treated during the past 5 years and have confirmed documentation
indicating lack of tolerability.;5. Subject may be included if they have previously experienced a benefit for their UC from infliximab and discontinued its use due to a subsequent loss of response (i.e., judged by the Investigator to have responded to infliximab in the past and subsequently experienced an overall lack of improvement or worsening of UC related symptoms) or intolerance (i.e., in the opinion of the investigator therapy was discontinued as a result of a significant acute or delayed infusion/administration reaction to the medication). Confirmed documentation indicating loss of response or lack of tolerability will be required.;6. If female, subject is either not of childbearing potential, defined as postmenopausal for at least
1 year or surgically sterile (bilateral tubal ligation, bilateral oophorectomy and/or hysterectomy) or

guidelines, whichever is longer) of an ongoing TB prophylaxis or have documented completion of a full course of TB prophylaxis, prior to Baseline.;9. Subject is judged to be in otherwise good health as determined by the Principal Investigator based upon the results of medical history, laboratory profile, physical examination, chest x-ray, and a 12-lead
electrocardiogram (ECG) performed during Screening.;10. Subject must be able and willing to self-administer subcutaneous (SC) injections or have a qualified person available to administer SC injections.
