Fluorescence imaging of a new drug for inflammatory bowel disease

Investigating the Safety, Feasibility, and Optimal Dose of Fluorescently Labeled Adalimumab-680LT for Visualizing Drug Targeting in Inflammatory Bowel Diseases

Phase1; Phase2 Interventional University Medical Center Groningen · NCT06117423

This study is testing a new version of a drug for inflammatory bowel disease to see how safe it is and how well it works in helping patients with Crohn's Disease and Ulcerative Colitis.

What this trial studies

This study evaluates the safety and optimal dosing of a fluorescently labeled version of adalimumab, known as adalimumab-680LT, in patients with Crohn's Disease and Ulcerative Colitis. The goal is to visualize and quantify the local concentration of the drug using fluorescence molecular imaging, which may help predict treatment response. Patients eligible for adalimumab therapy and with active disease will be included, and the study will involve both in vivo and ex vivo imaging techniques. The research is being conducted at the University Medical Center Groningen.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with an established diagnosis of Crohn's Disease or Ulcerative Colitis and active disease.

Not a fit: Patients who are pregnant, breastfeeding, or have recently undergone anti-TNF therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved prediction of treatment responses for patients with inflammatory bowel disease.

How similar studies have performed: While the use of fluorescence imaging in this context is novel, similar approaches in other areas have shown promise.
