Managing inflammatory bowel disease patients with anti-TNF biological medicines such as Adalimumab is challenging. Patients may respond well to treatment initially, only to encounter loss or response further ahead in their treatment pathway. Others may not respond to treatment at all. One approach to potentially improve outcomes for patients on Adalimumab is to measure trough drug levels and to determine if patients have developed antibodies to the drug. However, drug level and antibody testing will only be useful if it actually creates positive outcomes for patients. The challenge lies in optimising when these analyses take place and how best to interpret the data in making clinical decisions that benefit patients.
