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:
a. Investigator judgment that the subject is likely to require colectomy within 12 wks of Baseline
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;
3. Have severe, fixed symptomatic stenosis of the large or small intestine;
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;

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

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.
