Clinical trial Recruiting at 3 sites Interventional Ages 18 and up

Identifying autoantibodies before immune therapy for cancer

Official title: Prospective Study of Autoimmune Endocrine Disease-related Antibodies Before the Start of Immune Checkpoint Inhibitor Therapy

Run by Brugmann University Hospital · NCT06993727 · Data updated 2026-11-12

This study is testing if certain antibodies in the blood can help predict if cancer patients will have side effects from immune therapy and how well the treatment might work for them.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients eligible for immune checkpoint therapy who consent to participate in the study.

Probably not a fit

Patients who are pregnant will not benefit from this study due to exclusion criteria.

What this trial studies

This study aims to identify biomarkers that predict the development of autoimmune side effects in patients undergoing immune checkpoint inhibitor therapy for cancer. By analyzing blood samples for specific autoantibodies, the researchers hope to determine if the presence of these antibodies can indicate both the likelihood of adverse effects and the potential for improved cancer outcomes. The focus is particularly on thyroid autoantibodies and their correlation with thyroiditis and oncologic prognosis, as well as exploring less common endocrinopathies. The study will include all eligible patients consenting to participate at the specified locations in Brussels.

Why it matters

Potential benefit: If successful, this study could help identify patients at risk for autoimmune side effects while also predicting better cancer treatment outcomes.

How similar studies have gone: While the approach of identifying biomarkers for autoimmune reactions in immunotherapy is gaining interest, this specific focus on endocrine autoantibodies is relatively novel.
