Primary Outcome Measures :
  1. Proportion of Participants Who Achieve Endoscopic Response [ Time Frame: Week 14 ]
    Endoscopic response is defined as ≥ 50% decrease from baseline in simple endoscopic score in Crohn's disease (SES-CD)


Secondary Outcome Measures :
  1. Proportion of Participants Who Achieve Clinical Remission Worst Daily Abdominal Pain With Loose/Watery Stool Frequency Scores (APSF) [ Time Frame: Week 14 ]
    Clinical remission APSF is defined as unweighted average worst daily abdominal pain (AP) score ≤ 1 (using a 4-point scale; ie, 0 [none] to 3 [severe]) and unweighted average daily loose/watery (Bristol Stool Form Scale [BSFS] type 6 or 7) SF score ≤ 3.

  2. Number and Severity of Adverse Events [ Time Frame: Up to Week 66 ]
