Description of intervention(s) / exposure
Treatment: Drugs - TD-1473 Dose A
Treatment: Drugs - TD-1473 Dose B
Treatment: Drugs - TD-1473 Dose C
Treatment: Drugs - Placebo

Experimental: Active Treatment TD-1473 Dose A - Participants will be randomized to receive an oral daily dose of TD-1473. Responders will be re-randomized into the Phase 3 Maintenance portion of the study. Non-responders may participate in an extended induction.

Experimental: Active Treatment TD-1473 Dose B - Participants will be randomized to receive an oral daily dose of TD-1473. Responders will be re-randomized into the Phase 3 Maintenance portion of the study. Non-responders may participate in an extended induction.

Experimental: Active Treatment TD-1473 Dose C - Participants will be randomized to receive an oral daily dose of TD-1473. Responders will be re-randomized into the Phase 3 Maintenance portion of the study. Non-responders may participate in an extended induction.

Placebo comparator: Placebo - Participants will be randomized to receive an oral daily dose of placebo. Participants who received Placebo (and were non-responders) may move to an extended induction. Subjects who are on placebo will be assigned to active TD-1473 for the extended induction (they will be blinded to dose).
