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 Early withdrawn subjects during the first treatment phase cannot enter the extension phase.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.

Arms and Interventions

Arm Intervention/treatment
Active Comparator: SHR0302 dose A
Participants randomized in this arm will receive dose A of SHR0302 until end of study at week 24.
 Drug: SHR0302
The study drug, SHR0302, is designed to block the activity of an enzyme protein called JAK (known as a JAK inhibitor).
Experimental: SHR0302 dose B
Participants randomized in this arm will receive dose B of SHR0302 until end of study at week 24.
 Drug: SHR0302
The study drug, SHR0302, is designed to block the activity of an enzyme protein called JAK (known as a JAK inhibitor).
Experimental: SHR0302 dose C
Participants randomized in this arm will receive dose C of SHR0302 until end of study at week 24.
 Drug: SHR0302
The study drug, SHR0302, is designed to block the activity of an enzyme protein called JAK (known as a JAK inhibitor).
Placebo Comparator: Placebo
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.
 Drug: SHR0302
The study drug, SHR0302, is designed to block the activity of an enzyme protein called JAK (known as a JAK inhibitor).

Primary Outcome Measures :
  1. The percentage of subjects achieving clinical remission at week 12. [ Time Frame: week12 ]
    The percentage of subjects achieving clinical remission at week 12, defined as Crohn's Disease Activity Index (CDAI) score < 150.


Secondary Outcome Measures :
  1. The percentage of subjects achieving clinical remission defined as mean daily stool frequency (SF) ≤2.5, and abdominal pain (AP) ≤ 1 using the Patient Reported Outcome from CDAI at week 1, 4, 8, 12, 13, 16, and 24. [ Time Frame: week 1, 4, 8, 12, 13, 16, and 24 ]
    The percentage of subjects achieving clinical remission defined as mean daily stool frequency (SF) ≤2.5, and abdominal pain (AP) ≤ 1 using the Patient Reported Outcome from CDAI at week 1, 4, 8, 12, 13, 16, and 24.

  2. The percentage of subjects achieving clinical remission defined as PRO2 < 8 at week 1, 4, 8, 12, 13, 16, and 24. [ Time Frame: week 1, 4, 8, 12, 13, 16, and 24 ]
    The percentage of subjects achieving clinical remission defined as PRO2 < 8 at week 1, 4, 8, 12, 13, 16, and 24.

  3. The percentage of subjects achieving clinical response defined as a CDAI decrease from baseline of ≥ 100 points at week 1, 4, 8, 12, 13, 16, and 24. [ Time Frame: week 1, 4, 8, 12, 13, 16, and 24 ]
    The percentage of subjects achieving clinical response defined as a CDAI decrease from baseline of ≥ 100 points at week 1, 4, 8, 12, 13, 16, and 24.
