Study Arms:
- SHR0302 8mg QD (Type: EXPERIMENTAL): Participants randomized in this arm will receive SHR0302 8mg QD for the treatment phase. All participants that had completed the 8-week treatment phase (non-responders or responders) had the option to enter a blinded 8-week extension phase to continue to receive SHR0302 8mg QD.~Those who had completed the first 8-week of the treatment phase, but decided not to enter into the extension phase were also required to attend the 2-week follow-up visit. Participants who immaturely withdrew during the first treatment phase could not enter the extension phase.~SHR0302: The study drug, SHR0302, is designed to block the activity of an enzyme protein called JAK (known as a JAK inhibitor).
- SHR0302 4mg BD (Type: EXPERIMENTAL): Participants randomized in this arm will receive SHR0302 4mg BD for the treatment phase. All participants that had completed the 8-week treatment phase (non-responders or responders) had the option to enter a blinded 8-week extension phase to continue to receive SHR0302 4mg BD.~Those who had completed the first 8-week of the treatment phase, but decided not to enter into the extension phase were also required to attend the 2-week follow-up visit. Participants who immaturely withdrew during the first treatment phase could not enter the extension phase.~SHR0302: The study drug, SHR0302, is designed to block the activity of an enzyme protein called JAK (known as a JAK inhibitor).
- SHR0302 4mg QD (Type: EXPERIMENTAL): Participants randomized in this arm will receive SHR0302 4mg QD for the treatment phase. All participants that had completed the 8-week treatment phase (non-responders or responders) had the option to enter a blinded 8-week extension phase to continue to receive SHR0302 4mg QD.~Those who had completed the first 8-week of the treatment phase, but decided not to enter into the extension phase were also required to attend the 2-week follow-up visit. Participants who immaturely withdrew during the first treatment phase could not enter the extension phase.~SHR0302: The study drug, SHR0302, is designed to block the activity of an enzyme protein called JAK (known as a JAK inhibitor).
- placebo (Type: PLACEBO_COMPARATOR): Participants randomized in this arm will receive the placebo until week 8, and then will be re-randomized into one of the 3 active arms ( 4mg QD, 4mg BD, 8mg QD of SHR0302) in a 1:1:1 allocation ratio until the end of the study at week 16.~Those who had completed the first 8-week of the treatment phase, but decided not to enter into the extension phase were also required to attend the 2-week follow-up visit. Participants who immaturely withdrew during the first treatment phase could not enter the extension phase.~SHR0302: The study drug, SHR0302, is designed to block the activity of an enzyme protein called JAK (known as a JAK inhibitor).~Placebos: Placebo Oral Tablet
