E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to compare the percentage of subjects in complete (clinical and endoscopic) remission after 12 months of maintenance treatment with 2.4g/day MMX mesalamine/mesalazine given once daily (QD) between subjects who were in complete remission and subjects who were in partial remission at the end of 8 weeks acute treatment with 4.8g/day MMX mesalamine/mesalazine given QD. |
|
E.2.2 | Secondary objectives of the trial |
1. To compare the percentage of subjects in clinical remission at 12 months between subjects who were in complete remission and subjects who were in partial remission at the end of 8 weeks acute treatment.
2. To compare the time to relapse between subjects who were in complete remission and subjects who were in partial remission at the end of 8 weeks acute treatment.
3. To compare the percentage of subjects who achieve or maintain mucosal healing (endoscopy score ≤1) at 12 months between subjects who were in complete remission and subjects who were in partial remission at the end of 8 weeks acute treatment.
4. To assess the improvement in symptoms at 3 and 8 weeks of acute treatment.
5. To assess the percentage of subjects who achieve complete remission at the end of 8 weeks acute treatment.
6. To assess the safety and tolerability of MMX mesalamine/mesalazine. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Subjects meeting all of the criteria listed below at screening may be included in the study:
1. Adults aged 18 years or older.
2. Male, or non-pregnant, non-lactating female who agrees to comply with any applicable contraceptive requirements of the protocol.
3. Diagnosis of active mild to moderate UC (acute flare or newly diagnosed with a total score of 4–10 inclusive on the modified UC-DAI with an endoscopy score of ≥1 and a PGA of ≤2)*. The original diagnosis of UC must be established by endoscopy, colonoscopy, or barium enema and have compatible histology.
4. Stable maintenance therapy of 5-ASA ≤3.2g/day (excluding MMX mesalamine/mesalazine), if 5-ASA is being taken at the onset of acute flare. Stable maintenance therapy is defined as no change in dose, or no initiation of 5-ASA, from the onset of the acute flare through baseline. |
|
E.4 | Principal exclusion criteria |
Subjects are excluded from the study if any of the following criteria are met at screening:
1. Severe UC (assessed by PGA =3).*
2. Acute flare with onset >6 weeks prior to baseline.
3. Acute flare while on maintenance MMX mesalamine/mesalazine (LIALDA®, MEZAVANT®, MEZAVANT® XL,MEZAVANT® LP).
4. Unsuccessfully treated current acute flare using steroids or 5-ASA doses >3.2g/day.
5. Acute flare on a 5-ASA maintenance therapy of >3.2g/day.
6. Systemic or rectal steroids use within the 4 weeks prior to screening or immunosuppressants within the last 6 weeks prior to screening.
7. History of biologic (anti-TNF agent) use.
8. Antibiotic use or repeated use (>3 consecutive days of use at doses above the prescribed over-the-counter dose) of any anti-inflammatory drugs, including non-steroidal anti-inflammatory drugs such as aspirin, COX-2 inhibitors or ibuprofen, within 7 days prior to screening. However, prophylactic use of a stable dose of aspirin up to 325mg/day for cardiac disease is permitted.
9. Current or recurrent disease, other than UC, that could affect the colon, the action, absorption, or disposition of the investigational medicinal product, or clinical or laboratory assessments.
* The symptom parameters of the modified UC-DAI (rectal bleeding and stool frequency) will be assessed at screening and baseline, and endoscopy and PGA scores will be obtained at baseline to confirm eligibility. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is to compare the proportion of subjects in complete (clinical and endoscopic) remission after 12 months of maintenance treatment with 2.4g/day MMX mesalamine/mesalazine given QD between subjects who were in complete remission and subjects who were in partial remission at the end of 8 weeks acute treatment with 4.8g/day MMX mesalamine/mesalazine given QD.
Complete (clinical and endoscopic) remission is defined as a modified UC-DAI ≤1 with a score of 0 for rectal bleeding and stool frequency and at least a 1-point reduction in endoscopy score from baseline (Visit 0).
Partial remission is defined as a modified UC-DAI ≤3 with a combined stool frequency and rectal bleeding score of ≤1 and not in complete remission. |
