Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

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).
