Evaluation of the Predictive Value of Early Serum Trough Concentrations and Anti-drug Antibodies of Brodalumab and the Development of Concentration-response Curve of Brodalumab of Psoriasis Patients.
Biologics, such as brodalumab, are currently the most effective treatment option for patients with moderate-to-severe psoriasis. But they are costly for health care systems and prescribed according to a 'one dose fits all' dosing regimen, leading to potential over- and undertreatment. Within this study we aim to investigate the predictive value of early serum trough levels of brodalumab and determine the therapeutic window of brodalumab in psoriasis patients.
