Primary outcomes

  1. Change in Disease Activity by Harvey Bradshaw Index

    Time frame: 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

  2. Change in Disease Activity by Fecal Calprotectin (FCP)

    Time frame: 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.

Secondary outcomes

  1. The Change in High-sensitivity C-reactive Protein (hsCRP)

    Time frame: enrollment visit (baseline) and 15 days

    A secondary outcome measure will be the change in high-sensitivity C-reactive protein between the enrollment visit and day 15. The high-sensitivity C-reactive protein is a blood test which measures systemic inflammation.

  2. Safety and Tolerability of the Treatment Regimen Based on Medication Side Effects and/or Adverse Events (AEs).

    Time frame: 105 days

    Number of Medication Side Effects and/or Adverse Events (AEs)
