Mesalamine 2 g Sachet for the Maintenance of Clinical and Endoscopic Remission in Ulcerative Colitis (UC)

The proportion of subjects with remission was defined by Clinical and Endoscopic Response Score: 0 for rectal bleeding; 0 or 1 for stool frequency; 0 or 1 for endoscopic score. The Clinical and Endoscopic Response Score ranged between 0 (normal) to 9 (severe disease), higher scores indicating greater disease severity. The score included clinical response component to assess subject's symptoms and endoscopic response component to assess objective evidence of inflammation. Clinical response component had two subscales: stool frequency ranging from 0 (normal number of stools) to 3 (\>=5 stools more than normal) and rectal bleeding ranging from 0 (no blood seen) to 3 (blood alone passes). The Endoscopic response component had one subscale: flexible sigmoidoscopy/colonoscopy ranging from 0 (normal) to 3 (severe disease). Data is presented cumulative for all pathways.

The IBDQ is an instrument used to assess quality of life in adult subjects with ulcerative colitis. It includes 32 questions on 4 domains of Health-Related Quality-of-Life (HRQOL): Bowel Systems (10 items), Emotional Function (12 items), Social Function (5 items), and Systemic Function (5 items). Subjects were asked to recall symptoms and quality of life from the last 2 weeks and rate each item on a 7-point Likert scale (1=worst to 7=best). The total IBDQ was computed as the sum of the responses to the individual IBDQ questions. The total score can range between 32 to 224 with higher scores indicating a better HRQOL. The adjusted mean change from baseline at Month 2, 4, and 6 for the IBDQ total scores were reported. Data is presented cumulative for all pathways.

An AE is defined as any untoward medical occurrence in a subject participating in a clinical trial. Any AEs includes serious as well as non-serious AEs. An SAE is defined as any untoward medical occurrence that at any dose resulted in death, was life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, resulted in a congenital anomaly/birth defect, or was an important medical event. Any AE which occurred in the time interval from initial dosing (investigational medicinal product \[IMP\] intake) to the end of treatment visit (Month 6) was considered treatment-emergent. Data is presented cumulative for all pathways.

Time frame: Up to Month 6

Population: The analysis was based on safety analysis set which included all subjects who received at least 1 dose of IMP.

The proportion of subjects in clinical remission was defined as a score of 0 for rectal bleeding and 0 or 1 for stool frequency based on clinical response score component of the Clinical and Endoscopic Response Score. Clinical response score component had two subscales to assess subject's symptoms: rectal bleeding ranging from 0 (no blood seen) to 3 (blood alone passes) and stool frequency ranging from 0 (normal number of stools) to 3 (\>=5 stools more than normal). The scores of clinical response component ranged from 0 (normal) to 6 (severe disease), higher scores indicating greater disease severity. Data is presented cumulative for all pathways.

The proportion of subjects with an increase from baseline in the Clinical and Endoscopic Response Score by 2 or more points in at least 1 component, or by 1 or more points in at least 2 components were reported. The Clinical and Endoscopic Response Score ranged between 0 (normal) to 9 (severe disease), higher scores indicating greater disease severity. The score included clinical response component to assess subject's symptoms and endoscopic response component to assess objective evidence of inflammation. Clinical Response component had two subscales: stool frequency ranging from 0 (normal number of stools) to 3 (\>=5 stools more than normal) and rectal bleeding ranging from 0 (no blood seen) to 3 (blood alone passes). The Endoscopic Response component had one subscale: flexible sigmoidoscopy/colonoscopy ranging from 0 (normal) to 3 (severe disease). Data is presented cumulative for all pathways.
