Primary Outcome Measures
NameTimeMethod
Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events (SAEs)Up to Week 48 (up to 30 days following discontinuation of the study drug)

A TEAE was defined as any adverse event (AE) that occurred after the first dose of study drug in the APD334-005 (NCT02536404) study, including any AE that started in Study APD334-003 (NCT02447302) and was ongoing, worsened, or ended in Study APD334-005. A SAE was any untoward medical occurrence that at any dose resulted in the following outcomes: death, was life-threatening, required/prolonged hospitalization, disability/incapacity, congenital anomaly/birth defect, and important medical events.

Secondary Outcome Measures
NameTimeMethod
Proportion of Participants Who Achieved Clinical Response at Week 12 in APD334-003 and Maintained Clinical Response at Week 46 in APD334-005Week 12 (core study APD334-003) and Week 46 (extension study APD334-005)

A participant was considered to have achieved clinical response if he/she met the criteria of clinical remission or met criteria of clinical response. Clinical remission was defined as individual subscores of the 3-component Mayo Clinic score as follows: (1) an endoscopy score (using flexible proctosigmoidoscopy) of 0 or 1, (2) a rectal bleeding score of 0, and (3) a stool frequency score of 0 or 1 with a decrease of ≥ 1 point at Week 46 compared to APD334-003 baseline. Clinical response was defined as a decrease in 3-component Mayo Clinic score of ≥ 2 points and at least 30% with either a decrease of rectal bleeding of ≥ 1 or rectal bleeding score of 0 or 1 at Week 46 compared with baseline of study APD334-003. A score of 0 = normal and 1 = mild disease.

Proportion of Participants Who Achieved Clinical ResponseWeek 46 (extension study APD334-005)

A participant was considered to have achieved clinical response if he/she met the criteria of clinical remission or met criteria of clinical response. Clinical remission was defined as individual subscores of the 3-component Mayo Clinic score as follows: (1) an endoscopy score (using flexible proctosigmoidoscopy) of 0 or 1, (2) a rectal bleeding score of 0, and (3) a stool frequency score of 0 or 1 with a decrease of ≥ 1 point at Week 46 compared to APD334-003 baseline. Clinical response was defined as a decrease in 3-component Mayo Clinic score of ≥ 2 points and at least 30% with either a decrease of rectal bleeding of ≥ 1 or rectal bleeding score of 0 or 1 at Week 46 compared with baseline of study APD334-003. A score of 0 = normal and 1 = mild disease.

Proportion of Participants Who Achieved Clinical RemissionWeek 46 (extension study APD334-005)

A participant was considered to have achieved clinical remission if he/she had: (1) an endoscopy score (using flexible proctosigmoidoscopy) of 0 or 1, (2) a rectal bleeding score of 0, and (3) a stool frequency score of 0 or 1 with a decrease of ≥ 1 point at Week 46 compared with baseline of study APD334-003. A score of 0 = normal and 1 = mild disease.

Proportion of Participants Who Achieved Clinical Remission at Week 12 in APD334-003 and Also Maintained Clinical Remission at Week 46 in APD334-005Week 12 (core study APD334-003) and Week 46 (extension study APD334-005)

A participant was considered to have achieved clinical remission if he/she had: (1) an endoscopy score (using flexible proctosigmoidoscopy) of 0 or 1, (2) a rectal bleeding score of 0, and (3) a stool frequency score of 0 or 1 with a decrease of ≥ 1 point at Week 46 compared with baseline of study APD334-003. A score of 0 = normal and 1 = mild disease.
