Study Description

Brief Summary:

Crohn's disease and ulcerative colitis affect about 1.6 to 3 million people in the United States with many of those being young children and adolescents. Physicians need better ways to inform decisions on therapy selection and recognize ongoing intestinal injury while on treatment.

The main reason for this research study is to see if a blood test or stool test, which measures specific proteins, taken just before starting a new treatment for Crohn's disease can predict a patient's ability to achieve complete intestinal healing. The investigators also want to see if the intensity of gut inflammation can be detected by measuring a separate set of proteins in the blood.

Condition or disease	Intervention/treatment
Crohn's Disease; IBD	Drug: Infliximab; Drug: Adalimumab

Detailed Description:

Despite the heterogeneity of CD phenotypes and a potentially aggressive course of inadequately treated CD, treatment selection for newly diagnosed patients is currently based on clinical factors which do not define CD sub-types. Now, with additional biologic therapies for CD, there is a critical need for individual biochemical analysis both pre-treatment, and following induction to assess the probability of durable remission. These data will inform decisions on continued dosing of the current biologic, or whether addition of combination therapy or switching to a therapy with an alternative mechanism of action will be more beneficial.

The Food & Drug Administration (FDA) defines a companion diagnostic as a device that can identify patients most likely to benefit from a therapy or a device to monitor response with the purpose to adjust the treatment to achieve improved effectiveness.Our global aim is to develop a companion diagnostic (peripheral blood panel) that accurately predicts the probability of deep remission (clinical remission with MH) to anti-TNF and a protein (blood) biomarker panel that reproducibly distinguishes endoscopic MH from active (ulcerated) intestinal inflammation in patients with CD.

The long-term strategy is to utilize the "low-risk" anti-TNF specific module (protein panel) to personalize CD therapy. With the addition of new biologics for CD, patients with a low-risk inflammatory profile would not only be expected to achieve MH but also predicted to respond to treatment escalation strategies while avoiding or stopping the drug (if drug exposure is optimized) sooner in patients in which the protein profile predicts a low probability of deep remission with anti-TNF. As additional therapies are approved for pediatric CD, the priority would be to avoid anti-TNF in patients with a "high-risk" protein profile and specifically select therapies that target the patient's individual inflammatory signature. Additionally, the investigators expect the protein profile of patients failing to achieve deep remission to provide further insight into molecular mechanisms contributing to the continued inflammation and thereby directing the next therapeutic option.

Groups and Cohorts

Group/Cohort	Intervention/treatment
Phase I - Cross-sectional Study (CD and Suspected IBD); 150 children and young adults who have been previously diagnosed with CD (anti-TNF naïve) or suspected of having IBD (based on clinical symptoms and laboratory testing) who are scheduled for a clinically-indicated colonoscopy are eligible to be enrolled in this cohort.

Drug: Infliximab; No standard dosing regimen will be used and the dose will be determined by the treating physician; Other Name: Remicade; Drug: Adalimumab; No standard dosing regimen will be used and the dose will be determined by the treating physician; Other Name: Humira
