Secukinumab dosing every 2 weeks demonstrated superior efficacy compared with dosing every 4 weeks in patients with psoriasis weighing 90 kg or more: results of a randomized controlled trial.

Secukinumab 300 mg Q2W demonstrated superior and sustained efficacy compared with Q4W in patients with moderate-to-severe plaque psoriasis weighing ≥ 90 kg. PASI 90 nonresponders derived additional benefits from uptitration to a Q2W regimen (ClinicalTrials.gov identifier: NCT03504852). What is already known about this topic? Obesity is a common comorbidity of psoriasis and can attenuate response to biologic treatment. Secukinumab is a fully human monoclonal antibody that selectively neutralizes interleukin-17A in the treatment of moderate-to-severe plaque psoriasis. Subgroup analyses of previous study results and pharmacokinetic/pharmacodynamic modelling data suggest that heavier patients may benefit from higher exposure to secukinumab through an increased dosing frequency [300 mg every 2 weeks (Q2W) vs. every 4 weeks (Q4W)]. What does this study add? Over 52 weeks, secukinumab 300 mg Q2W demonstrated superior efficacy compared with secukinumab 300 mg Q4W in patients with moderate-to-severe plaque psoriasis weighing ≥90 kg, with comparable safety results, consistent with the established secukinumab safety profile. In patients who did not achieve PASI 90 at week 16 on the Q4W regimen, uptitration to the Q2W regimen at week 16 resulted in improved efficacy responses through week 52 after switching.
