简要总结
The purpose of the study is to evaluate dose response of JNJ-54781532 in participants with moderately to severely active ulcerative colitis (UC).
详细描述
This is a Phase 2b, multicenter, randomized (the study medication is assigned by chance), double-blind (neither physician nor participant knows the treatment that the participant receives), placebo-controlled (an inactive substance that is compared with a medication to test whether the medication has a real effect in a clinical study), parallel-group (each group of participants will be treated at the same time), dose-response study (a study to evaluate response to different dosages of study medication) of oral tablets of JNJ-54781532 in adult participants with moderately to severely active UC. Approximately 220 participants will be randomized in a 1:1:1:1:1 ratio to 1 of 5 treatment groups at Week 0 (placebo; JNJ-54781532 25 mg once daily; JNJ-54781532 75 mg once daily; JNJ-54781532 150 mg once daily; and JNJ-54781532 75 mg twice daily) to receive their randomized dosage of study medication through Week 8 and will be assessed for clinical response at Week 8. Participants who achieve clinical response at Week 8 will continue to receive their original randomized dosage of study medication through Week 32. Participants who do not achieve clinical response at Week 8 will be treated as follows: participants originally randomized to placebo will receive JNJ-54781532 150 mg once daily through Week 16; participants originally randomized to JNJ-54781532 will continue to receive their original randomized dosage of JNJ-54781532 through Week 16. Participants who were not in clinical response at Week 8 and do not achieve a partial Mayo score response (a decrease from baseline in the partial Mayo score by ≥3 points) at Week 16 will be discontinued from study medication; and those who achieve a partial Mayo score response at Week 16 can continue receiving JNJ 54781532 through Week 32. Participants will be evaluated for safety (adverse events) up to Week 36 (ie, 4 weeks after the last dose of study medication). The maximum study duration for each participant will be approximately 44 weeks (including maximum screening period).

研究组 & 干预措施
Placebo
Participants will receive placebo once daily from Week 0 to Week 8. Participants in clinical response at Week 8 will continue to receive placebo through Week 32. Participants not in clinical response at Week 8 will receive treatment with 150 mg JNJ-54781532 orally once daily from Week 8 to Week 16. Participants who achieve a partial Mayo score response (ie, a change from baseline of ≥3 in the partial Mayo score) at Week 16 can continue receiving 150 mg JNJ-54781532 orally once daily through Week 32
干预措施: Placebo (Drug)

结局指标
主要结局
Change from baseline in the Mayo score at Week 8
时间窗: Week 8
The Mayo score is the primary tool for assessing ulcerative colitis activity. The Mayo score consists of 4 subscores (stool frequency, rectal bleeding, findings of endoscopy, and physician's global assessment) which range from 0 to 3. The Mayo score is calculated as the sum of these 4 subscores and can range between 0 and 12. A score of 3 to 5 points indicates mildly active disease; a score of 6 to 10 indicates moderately active disease; and a score of 11 to 12 indicates severe disease.
次要结局
- Number of participants with clinical remission at Week 8(Week 8)
- Number of participants with mucosal healing at Week 8(Week 8)
- Number of participants with clinical response at Week 8(Week 8)
