Description of intervention(s) / exposure
Treatment: Drugs - Placebo
Treatment: Drugs - TD-1473

Active comparator: Active Treatment TD-1473 with Dose A - 1 oral Dose A daily of TD-1473 for 12 weeks in subjects with moderately to-severely active CD.

Subjects who complete Induction will continue to receive TD-1473 at Dose A in the Active Treatment Arm for up to 48 additional weeks.

Active comparator: Active Treatment TD-1473 with Dose B - 1 oral Dose B daily of TD-1473 for 12 weeks in subjects with moderately to-severely active CD.

Subjects who complete Induction will continue to receive TD-1473 at Dose B in the Active Treatment Arm for up to 48 additional weeks.

Placebo comparator: Placebo - 1 oral dose daily of placebo for 12 weeks in subjects with moderately to-severely active CD.

Subjects who complete Induction will receive TD-1473 at Dose A in the Active Treatment Arm for up to 48 additional weeks.


Treatment: Drugs: Placebo
Placebo will be taken daily by mouth (orally) for up to 12 weeks in the morning before eating.

Treatment: Drugs: TD-1473
TD-1473, at Dose A or Dose B depending upon arm, will be taken daily by mouth (orally) for up to 12 weeks in the morning before eating. An additional 48 weeks either at Dose A or Dose B, depending on arm, may be administered if subjects finish the 12 week induction period.
