Medico-economic Evaluation of the Therapeutic Drug Monitoring of Anti-TNF-α Agents in Inflammatory Bowel Diseases
A study testing Immuno monitoring in people with Crohn's Disease and Ulcerative Colitis, run by University Hospital, Montpellier at 1 site in France.
Trial summary
Since their appearance more than a decade ago, anti-tumor necrosis factor (TNF) inhibitors have demonstrated beneficial activity in the treatment of inflammatory bowel diseases (IBD). However, more than one-third of patients present primary resistance, and one more third become resistant over time. Read more about this study

About this study
Official title: Medico-economic Evaluation of the Therapeutic Drug Monitoring of Anti-TNF Agents in the Management of Patients With Inflammatory Bowel Disease Treated With Anti-TNFalpha Biotherapy.
Since their appearance more than a decade ago, anti-tumor necrosis factor (TNF) inhibitors have demonstrated beneficial activity in the treatment of inflammatory bowel diseases (IBD). However, more than one-third of patients present primary resistance, and one more third become resistant over time. One of the main factors associated with loss of response is the immunogenicity of anti-TNF biologics leading to the production of antibodies targetting the TNF inhibitor, namely anti-drug antibodies (ADAbs), that accelerate drug elimination from the serum and decrease its therapeutic activity. In this study the investigators propose a medico-economic evaluation of the measurement of anti-TNF agents and anti-drug antibodies serum concentrations in the management of patients with inflammatory bowel disease treated with anti-TNFalpha inhibitors. 280 patients with Crohn's disease (CD) or ulcerative colitis (UC) will be included and randomized in 2 groups with or without drug and ADAbs monitoring. In the monitored group, in case of loss of response, the clinician will use biological informations to adapt the treatment following a simple treatment algorithm. In the unmonitored group, drug and ADAbs measurements will not be transmitted to the clinician. Clinical and economical benefits of the biological monitoring will be evaluated after a follow-up period of two years.
Read the detailed description
280 patients with Crohn's disease (CD) or ulcerative colitis (UC) will be recruited in 13 french centers and randomized in 2 groups with or without drug and ADAbs monitoring.
Anti-TNF inhibitors and ADAbs will be simultaneously measured in the patients serum by ELISA (LisaTracker - Theradiag) at weeks 6 and 24, months 4, 8, 12, 16, 20 and 24.
In the unmonitored group, drug and ADAbs measurements will not be transmitted to the clinician.
In the monitored group, in case of loss of response the clinician will use immunomonitoring data to adapt the treatment following a simple treatment algorithm:
- loss of response with therapeutic serum trough level of anti-TNF switch to another biologic
- loss of response with subtherapeutic serum trough level of anti-TNF but without detectable ADAbs increase doses and/or shorten interval between infusions
- loss of response with subtherapeutic serum trough level of anti-TNF and detectable ADAbs switch to another anti-TNF if inefficient switch to another biologic.
Clinical and economical benefits of the biological monitoring will be evaluated after a follow-up period of two years:
- primary outcome: Cost-utility analysis of the immunomonitoring strategy using incremental cost effectiveness ratio
- secondary outcome: Evaluation of the quality of life (IBDQ score)

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Since their appearance more than a decade ago, anti-tumor necrosis factor (TNF) inhibitors have demonstrated beneficial activity in the treatment of inflammatory bowel diseases (IBD). However, more than one-third of patients present primary resistance, and one more third become resistant over time. One of the main factors associated with loss of response is the immunogenicity of anti-TNF biologics leading to the production of antibodies targetting the TNF inhibitor, namely anti-drug antibodies (ADAbs), that accelerate drug elimination from the serum and decrease its therapeutic activity. In this study the investigators propose a medico-economic evaluation of the measurement of anti-TNF agents and anti-drug antibodies serum concentrations in the management of patients with inflammatory bowel disease treated with anti-TNFalpha inhibitors. 280 patients with Crohn's disease (CD) or ulcerative colitis (UC) will be included and randomized in 2 groups with or without drug and ADAbs monitoring. In the monitored group, in case of loss of response, the clinician will use biological informations to adapt the treatment following a simple treatment algorithm. In the unmonitored group, drug and ADAbs measurements will not be transmitted to the clinician. Clinical and economical benefits of the biological monitoring will be evaluated after a follow-up period of two years.

Questions about this trial
What is this clinical trial studying?
A study testing Immuno monitoring in people with Crohn's Disease and Ulcerative Colitis, run by University Hospital, Montpellier at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 30 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
cost-utility analysis of the immunomonitoring strategy (time frame: 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02508012, which also lists 15 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Sep 2025.
