Control Crohn Safe Trial

Study Purpose

Crohn's disease (CD) is a chronic disease with a heterogeneous clinical presentation, relapse rate and treatment response. Insufficient control of mucosal inflammation results in irreversible bowel damage and complications and at present no markers are available to predict such a complicated disease course at diagnosis. Therefore, to prevent overtreatment of low risk patients, step-up treatment with subsequent introduction of corticosteroids, thiopurines maintenance and TNF-blockers if a previous category fails is standard care. Combination treatment with thiopurines and a TNF-blocker is more effective than monotherapy but associated with a higher risk for infectious complications. Landmark studies convincingly showed an improved long-term outcome if the TNF-blocker infliximab is introduced early after diagnosis. The standard step-care approach thus prolongs steroid exposure and delays start of disease modifying biologicals in high risks patients. Given the higher efficacy of combination therapy with a thiopurine of infliximab and potential allergic reactions and lower response rates after re-initiation of this chimeric biological, temporary monotherapy with this TNF-blocker has not been studied as first line treatment before. Adalimumab is a humanised monoclonal antibody and subsequently, combination therapy of adalimumab + thiopurines has only a marginal effect on anti-drug anti-body formation. Furthermore, combination therapy with adalimumab does not enhance the clinical response. Therefore, periodic treatment with adalimumab in combination with close monitoring after drug-discontinuation, in newly diagnosed CD might improve outcome, reduce drug-related side effects while still preventing overtreatment. The aim of this study is to compare the long-term efficacy and safety of periodic adalimumab as initial treatment in newly diagnosed CD patients compared to standard step-care with corticosteroid/budesonide as the initial treatment

Recruitment Criteria

Accepts Healthy Volunteers

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

Study Type

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.

Eligible Ages 18 Years - 70 Years
Gender All

Trial Details

Trial ID:

This trial id was obtained from, 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.


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.
