  5. Change in Crohn's Disease Endoscopic Index of Severity (CDEIS) [ Time Frame: Baseline through week 26 ]
  6. Change in Inflammatory Bowel Disease Questionnaire (IBDQ) and Short Form 36 (SF-36) [ Time Frame: Baseline through Week 52 ]
  7. Change in inflammatory markers [ Time Frame: Baseline through Week 52 ]
  8. Proportion of subjects tapered off steroids [ Time Frame: Baseline through Week 52 ]
  9. Tissue levels of the active agents of RHB-104 in colon biopsy samples [ Time Frame: Baseline to Week 26 ]
