Evaluating the relationship between antidrug antibodies and efficacy and safety outcomes in patients with Fabry disease receiving enzyme replacement therapy: a systematic literature review. (PubMed, Orphanet J Rare Dis) - Jul 18, 2026 - "This SLR found evidence that ADA positivity may be associated with increased IRR risk and may have a negative effect on some measures of ERT efficacy. Inconsistencies in the identified data were likely driven by study design differences, including prior ERT exposure, follow-up time, and ADA assessment protocols. Additional prospective studies with standardized ADA assessments and accounting for patient baseline characteristics and disease severity, are needed to better understand the clinical implications of ADA formation on ERT outcomes, including an assessment of causality."
