Brief Summary

To investigate the influence of early therapeutic drug monitoring and dose optimization on disease outcome in Crohn's patients treated with Adalimumab.

Detailed Description

This is an investigator initiated randomized open label study. This study is designed to compare whether increasing the dose of adalimumab based on the level the drug in the blood to a target level early in the treatment course would lead to better outcomes for patients as compared to the standard doses.

GroupInterventionDescription
Standard clinical careAdalimumabAdalimumab induction as per standard clinical care: * Week 0: 160 mg SC * Week 2: 80 mg SC * Followed by 40 mg SC every 2 weeks' maintenance therapy
Active optimizationAdalimumabSame as Standard clinical care Arm, except: * If ADAL trough ≤15 μg/ml, dose escalation with 80 mg SC at week 6 followed by 40 mg SC every week * If ADAL trough \>15 μg/ml, no dose escalation and continued standard of care dosing
Primary Outcome Measures
NameTimeMethod
Proportion of subjects who achieved remissionWeek 12

Clinical remission will be scored by a Harvey-Bradshaw Index \< 5 AND Biochemical remission will be scored by C-reactive protein \< 5 mg/l OR Fecal calprotectin \<250 μg/g (combination endpoint)

Secondary Outcome Measures
NameTimeMethod
Proportion of steroid free subjectsAt Week 12

Steroid free defined as patients being steroid free at Week 12

Rates of complications12 weeks

Rates of complications, including hospitalization, surgery, adverse reaction, and corticosteroid use.

Proportion of subjects who achieved clinical responseFrom Week 0 to Week 12

Clinical response will be evaluated by a decreased in Harvey-Bradshaw Index score AND a decreased level of C-reactive protein OR Fecal calprotectin

Subjects well-beingFrom Week 0 to Week 12

Subjects well-being will be scored using the validated questionnaire Short inflammatory bowel disease questionnaire (SIBDQ)

Therapeutic drug monitoringAt Week 8, 12

Adalimumab drug concentration at week 8 and 12 AND proportion of subjects with antibody to Adalimumab at Week 8 and 12 on the rate i. Clinical response/remission (HBI\<5) ii. Biochemical response/remission (CRP within normal reference range) iii. Endoscopic response (SES-CD reduction of ≥50% from baseline) / remission (SES-CD ≤3)
