 The study investigates the correlation between adalamumab serum levels and clinical response measured as absolute posi in patients with psoriasis treated with adalamumab. Significant differences were found in serum trough levels between patients achieving an excellent response, an appropriate response and an inappropriate response. The therapeutic range for adalamumab serum levels was from 3.30 to 7.30 GML. Monitoring of absolute posi and serum levels can provide a personalized and cost-effective evaluation.
