Study to evaluate whether a fixed-dose of RHB-104 is safe and effective in subjects suffering from moderate to Severely Crohn’s disease. Subjects will be separated in two groups that will be treated in parallel to receive study drug or placebo. Neither the treating physician nor the subject will be aware of the actual treatment received.

Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective is to assess whether subjects randomized to receive RHB-104 have a higher probability of being in a state of remission at the 26 week assessment as compared to subjects randomized to receive placebo. ; Secondary Objective: Assess whether subjects randomized to receive RHB-104 have a higher probability of being in a state of 1) response at the 26 week assessment 2) remission at the 52 week assessment 3) remission in assessments from week 26 through week 52 4) remission at the 16 week assessment 5) steroid free remission at the 52 week assessment (subjects must be maintained off steroids for 3 weeks in order to be determined to be in steroid free remission e.g. by week 49.) as compared to subjects randomized to receive placebo. ;Primary end point(s): Remission (primary outcome measure) – Remission in a subject is defined as a CDAI score of <150. ;Timepoint(s) of evaluation of this end point: Week 26

Secondary

MeasureTime frame
Secondary end point(s): Response - A response in the individual subject is defined as reduction in CDAI score of =100 from Baseline;Timepoint(s) of evaluation of this end point: Week 26
