Exclusion criteria:
The subject will be excluded from entry if ANY of the criteria listed below are met:
1. Have severe extensive colitis as evidenced by:

OR
b. Subjects with at least 4 of these symptoms at Screening or Baseline visits as described in the protocol.
2. Require, or are required within the 2 mths prior to baseline, surgery for active gastrointestinal bleeding, peritonitis, intestinal obstruction, or intra-abdominal or pancreatic abscess requiring surgical drainage or other conditions possibly confounding the evaluation of disease activity;

4. Have current evidence of colonic obstruction or history within the 6 mths prior to baseline, confirmed with objective radiographic or endoscopic evidence of a stricture with resulting
5. Have a history of colonic mucosal dysplasia;
6. Presence on screening endoscopy of adenomatous colonic polyps, if not removed prior to study entry, or history of adenomatous colonic polyps that were not removed;
7. Have the presence of a stoma;
8. Have a history of extensive colonic resection that would prevent adequate evaluation of clinical disease activity
9. Have a positive stool culture for enteric pathogens, pathogenic ova or parasites within 4 months prior to Baseline unless subject has received treatment and had a negative stool examination 1 wk or longer after the end of treatment;
10. Have a concomitant diagnosis of CHF, including medically controlled asymptomatic subjects;
11. Have had serious infections within 2 mths of screening. Less serious infections need not be considered as an exclusion at the discretion of the investigator;

13. Have a known infection with HIV and/or hepatitis B or hepatitis C;

17. Presence of a transplanted organ (with the exception of a corneal transplant >3 months prior to screening);

Have a history of lymphoproliferative disease including lymphoma, or signs and symptoms suggestive of possible lymphoproliferative disease, such as lymphadenopathy of unusual size or location (eg, nodes in the posterior triangle of the neck, infra-clavicular, epitrochlear, or periaortic areas), or splenomegaly;
19. Have any current known malignancy or malignancy within 5 years prior to screening (except for squamous or basal cell carcinoma of the skin that has been treated with no evidence of recurrence);

Primary Outcome(s)

Primary end point(s): The primary efficacy endpoint for Part 1 of the study is the proportion of subjects in remission at Wk 16 (ie, total Mayo score of 2 points or lower, with no individual subscore exceeding 1 point, without the use of corticosteroids).The primary efficacy endpoint for Part 2 is the average remission rate over duration of treatment.

Main Objective: There are 2 parts. The primary objective of Part 1 of this study is to compare the proportion of subjects with moderate to severe active UC who achieve remission at Wk 16 on IFX/AZA combination therapy versus AZA monotherapy. Clinical remission at Wk 16 is defined as a total Mayo score of 2 points or lower, with no individual subscore exceeding one point, without the use of corticosteroids. The primary objective of Part 2 of this study is to determine whether remission in UC is better sustained by maintenance (q8w) or intermittent (upon relapse) infliximab treatment.

Secondary Objective: Part 1 of this study are:
- To compare the proportion of subjects with moderate to severe active UC who achieve remission at Wk 16 on infliximab monotherapy versus AZA monotherapy.
- To compare the proportion of subjects with moderate to severe active UC who achieve remission at Wk 16 on IFX/AZA combination therapy versus IFX monotherapy.
Secondary objectives for Part 2 are:
- To assess the long-term safety and efficacy of maintenance versus intermittent therapy with 5 mg/kg IFX in a moderate to severe active UC population.
-To assess mucosal healing
- To determine the number of colectomies.
- To determine the number of hospitalizations and unscheduled physician visits and surgeries due to UC.
- To determine the number and outcome of surgical procedures due to UC.
- To determine antibody formation to IFX in subjects who receive IFX monotherapy or IFX/AZA combination therapy as intermittent or maintenance IFX treatment in Part 2.
