A Phase 2 Multi-Center, Randomized, Double-Blind, Placebo˗Controlled, Parallel-Group Study to Evaluate the Efficacy and Safety of Induction Therapy With 2 Doses of TD-1473 in Subjects With Moderately-to-Severely Active Crohn's Disease

A Phase 2 study to evaluate the efficacy, safety and tolerability of TD-1473 in subjects with
moderately-to-severely active Crohn's Disease with up to 36 weeks of treatment.

A Phase 2 multi-center, randomized, double blind, placebo-controlled, parallel-group study to
evaluate the efficacy and safety of 12 weeks of induction therapy with TD˗1473 in subjects
with moderately-to-severely active CD. This study includes 3 phases: Screening, Induction,
and Active Treatment Extension (ATE). The Induction phase of the study is a randomized,
double blind, placebo controlled, parallel group study evaluating 2 oral dose levels of
TD-1473 compared to placebo for 12 weeks in subjects with moderately to-severely active CD.
Subjects who complete Induction will continue to receive TD-1473 in the ATE, for up to 24
additional weeks.

- Males and females with clinical evidence of Crohn's disease for at least 3 months
duration at screening

Disease Activity Index (CDAI) score of 220-450 inclusive

- SES-CD score of ≥ 6 (≥ 4 if isolated ileal disease) with ulceration (corresponding to
a score of 1) in at least 1 of the 5 ileocolonic segments on the Presence of Ulcers

- Is corticosteroid-dependent or has demonstrated inadequate response, or intolerance to
conventional therapy (aminosalicylates, corticosteroids and immunomodulators such as

investigational drug, whichever is longer, or is currently participating in another
trial of an investigational drug (or medical device)

- Subject has failed ≥ 3 biologic agents of 3 different mechanisms of action (i.e.,
