Total minimum score 0 (better), total maximum score 60 (worse).

  • Change in GSS From Baseline to Week 12 - ITT Population [ Time Frame: Baseline to Week 12 ]
    GSS - Abdominal Pain & Symptom Rating, scale 0-none (better) to 6-severe (worse) for each of the following categories: abdominal pain, abdominal tenderness, nausea/vomiting, bloating, constipation, diarrhea, mucus in stool, feeling urge to evacuate but no bowel movement, painful straining with bowel movement, pain/difficulty urinating. Total minimum score 0 (better), total maximum score 60 (worse).

  • Change in GSS From Baseline to Week 52 - ITT Population [ Time Frame: Baseline to Week 52 ]
