A Phase II Study in Patients With Moderate to Severe Active Crohn's Disease
- Registration Number
- NCT03677648
- Lead Sponsor
- Reistone Biopharma Company Limited
- Brief Summary
The proposed study is a randomized, double-blind, placebo-controlled, multi-center Phase II study to investigate the safety and efficacy of SHR0302 in patients with moderate to severe active Crohn's Disease. The study aims to evaluate the optimal dose of SHR0302 and time needed in inducing clinical remission in active CD. This is an 12+12 weeks study, in which participants who complete the first 12 weeks treatment phase, will have the option to enter a blinded active arms 12-week extension phase. Early withdrawn subjects during the first treatment phase cannot enter the extension phase. The total duration of the study participation, including extension and follow-up, will be approximately 26 weeks.
With the wealth of scientific evidence on JAK/STAT involvement in IBD, the data from similar class of new drugs and the current data on SHR0302 (JAK1 inhibitor), support the rationale to proceed with phase II studies to evaluate the efficacy and safety of SHR0302 in patients with moderate to severe active CD.

- Arm && Interventions
Group Intervention Description SHR0302 dose B SHR0302 Participants randomized in this arm will receive dose B of SHR0302 until end of study at week 24. SHR0302 dose C SHR0302 Participants randomized in this arm will receive dose C of SHR0302 until end of study at week 24. Placebo Placebos Participants randomized in this arm will receive placebo until week 12, and then will be re-randomized into one of the 3 active arms (dose A, dose B, and dose C of SHR0302) in a 1:1:1 allocation ratio until the end of study at week 24. SHR0302 dose A SHR0302 Participants randomized in this arm will receive dose A of SHR0302 until end of study at week 24. Placebo SHR0302 Participants randomized in this arm will receive placebo until week 12, and then will be re-randomized into one of the 3 active arms (dose A, dose B, and dose C of SHR0302) in a 1:1:1 allocation ratio until the end of study at week 24.
