Brief summary
A 3-Year Multi-Center, Long-Term Safety (LTS) Study to Evaluate the Safety and Tolerability of TD-1473 in Subjects with Ulcerative Colitis who have participated in the Maintenance Study of Protocol 0157
Detailed description
This is a multi-center, long-term safety study to evaluate the safety and tolerability of TD-1473 for up to 156 weeks (3 years) + 4 week follow-up in subjects with moderate to severe UC exiting the preceding Maintenance Study of Protocol 0157 (NCT03758443).

Outcome results
Number of Participants Who Experienced a Treatment-emergent Adverse Event (TEAE)
A TEAE was defined as any AE with a recorded start date on or after the date of the first dose of study drug up through 4 weeks after the last dose of study drug. Any clinically significant changes in laboratory safety tests, electrocardiograms (ECGs) and vital signs, were also recorded as TEAEs.
Time frame: Day 1 up to 4 weeks after last dose of study drug (median treatment duration was: TD-1473 20 mg - 142 days; TD-1473 80 mg - 180.0 days; TD-1473 200 mg - 158 days)
Population: Includes all participants from the Safety Analysis Set.
