A Phase II Study in Patients With Moderate to Severe Active Ulcerative Colitis.

Study Purpose

The proposed study is a randomized, double-blind,placebo-controlled, multi-center phase II study to investigatethe safety and efficacy of SHR0302 in patients with moderate to severe activeulcerative colitis. The study aims to evaluate the optimal dose of SHR0302 andtime needed in inducing clinical response in active ulcerative colitispatients. This is an 8+8 weeksstudy, in which participants who complete the first 8 weeks treatment phase, will have the option to enter a blinded activearms 8-week extension phase. Early withdrawn subjects during the first treatment phasecannot enter the extension phase. The total duration of the study participation, including extension and follow-up, will be approximately 18weeks. SHR0302 is a JAK1 inhibitor, capable of blocking JAK-STATs pathway and control inflammation. Therefore it has the potential to be a treatment for UC.

Recruitment Criteria

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Accepts Healthy Volunteers

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Trial ID:

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
