Status Recruiting

Clinical Trial Summary

Recently a smartphone application IBDoc® was developed to enable patients to measure faecal calprotectin at home in an easy way. In this HELP-AID trial we want to evaluate the value of these home based IBDoc® faecal calprotectin measurements in predicting short- and mid-term outcome to ADA induction therapy in patients with moderate-to-severe IBD.

Patients known with moderate-to-severe CD and ulcerative colitis starting ADA therapy will be asked to participate in this study. They will be asked to collect a stool sample at 3 different time points (week 0, 4 and 8). This faecal sample needs to be loaded on a test cassette with an extraction device. In a second step, the patient can turn his smartphone into an easy to use test cassette reader by taking a picture and using the CalApp® which is based on an immunochromatographic test. Finally, the CalApp® will transmit the test results securely to the health care professional.

In this study we want to evaluate the predictive value of absolute and relative faecal calprotectin values measured by IBDoc® on clinical, biological and endoscopic outcome at week

12. Furthermore, we want to evaluate the correlation between IBDoc® and classical ELISA measurements of faecal calprotectin, and the convenience of this system to the patient and the health care professional.

Clinical Trial Description

Adalimumab (Humira®), a fully human monoclonal antibody to TNF, has been given an important position in the treatment of patients with an inflammatory bowel disease (IBD). However, not all patients respond adequately to this relatively expensive and potentially toxic therapy. Adapting the standard treatment regimen to the individual needs of the patient may favor the short and long term outcome of this therapy.

Following daily clinical practice, patients will receive standard induction therapy with 160 mg adalimumab at week 0, followed by 80 mg adalimumab at week 2. Starting at week 4 patients will receive a maintenance therapy with 40 mg adalimumab every other week. If a patient shows an insufficient response, the dose can be increased to 40 mg adalimumab every week.

Defining predictors of response to ADA has become a major objective in scientific research. One of the predictors of response may be an early decrease in faecal calprotectin. Faecal calprotectin is a protein which presence in the stool of a patient correlates with endoscopic disease activity. A persistently elevated faecal calprotectin after start up with adalimumab treatment may suggest that this patient needs a higher dose.
