A Study in Patients With Moderate to Severe Active Crohn's Disease

Study Purpose

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 Early withdrawn subjects during the first treatment phase cannot enter the extension phase.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

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.

Searching Both is inclusive of interventional and observational studies.

Trial Details

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

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.
