结局指标
主要结局
Change in Disease Activity by Harvey Bradshaw Index
时间窗: enrollment visit (baseline) and 15 days
The primary endpoint will be the change in disease activity, as measured by Harvey-Bradshaw Index (HBI) score, between the enrollment visit and Day 15. All participants who withdraw for any reason prior to day 15 will be considered treatment failures. The HBI is a clinical score where points are given for each category below plus number of liquid bowel movements in previous day. A score of 3 or lower is considered remission. A score of 8 or higher is considered severe disease. General Well Being Very well 0 points Slightly below par 1 point Poor 2 points Very poor 3 points Terrible 4 points Abdominal Pain None 0 points Mild 1 point Moderate 2 points Severe 3 points Abdominal Mass None 0 points Dubious 1 point Definite 2 points Definite and tender 3 points Complications None 0 points Arthralgias +1 point Uveitis +1 point Erythema Nodosum + 1 point Aphthous ulcers +1 point Pyoderma Gangrenosum + 1 point Anal fissure + 1 point New fistula + 1
Change in Disease Activity by Fecal Calprotectin (FCP)
时间窗: enrollment visit (baseline) and 15 days
The second primary outcome measure will be the change in disease activity, as measured by fecal calprotectin, between the enrollment visit and day 15. The fecal calprotectin is a stool test which measures intestinal inflammation.
次要结局
- The Change in High-sensitivity C-reactive Protein (hsCRP)(enrollment visit (baseline) and 15 days)
- Safety and Tolerability of the Treatment Regimen Based on Medication Side Effects and/or Adverse Events (AEs).(105 days)
