摘要: During preclinical and clinical studies, immunoassays are used to measure the concentration of therapeutic antibody, anti-drug antibodies soluble protein biomarkers. The reliability these assays is crucial since results routinely for safety assessment dose selection. Furthermore, biomarkers can provide information about target engagement, proof mechanism, principle prediction response. Study samples mostly consist complex matrices that exhibit considerable interference, resulting in inaccurate measurements. This perspective discusses source interference strategies mitigate or eliminate during drug development drugs with a focus on antibodies.
