ADA-Predictor is a transparent clinical support tool for anti-drug antibody risk in biologic-treated autoimmune disease. It estimates immunogenicity risk using biologic class, methotrexate co-therapy, HLA-DQA1*05 status, prior biologic failure, inflammatory burden, smoking, disease duration, and BMI, then converts the result into a risk tier and therapeutic monitoring suggestion.

Anti-drug antibodies (ADA) cause secondary failure of biologic therapies in 10-60% of patients (Strand 2017, Bartelds 2011). ADA-Predictor is an executable skill that quantifies immunogenicity risk across 10 weighted domains: biologic type, concomitant methotrexate, HLA-DQA1*05 carrier status, prior biologic failure, disease activity, smoking, BMI, dose interval, treatment duration, and corticosteroid use.
