Over the period of 1 year, secukinumab 300 mg every 2 weeks demonstrated superior efficacy compared with secukinumab 300 mg every 4 weeks in overweight patients with moderate to severe plaque psoriasis, results from a multicenter, double-blind, parallel-group trial showed.
The more frequent dosing was also associated with comparable safety, consistent with the established secukinumab safety profile.
"Weight may have an impact on pharmacokinetics and, therefore, on the clinical outcome of biologic treatment for psoriasis," Matthias Augustin, MD, and colleagues wrote in the study, published recently in the British Journal of Dermatology. "Dose optimization may be highly beneficial for patients with higher body weight," they noted, adding that their study supports previous study findings and pharmacokinetic/pharmacodynamic modelling data, showing that secukinumab dosed every 2 weeks "leads to a clinically and statistically significant advantage in PASI 90 response," compared with standard dosing every 4 weeks in patients who weight 90 kg (about 198 pounds) or more, after 16 weeks of treatment, which was maintained until week 52.
For the studyAugustin, of the Institute for Health Services Research in Dermatology and Nursing at University Medical Center Hamburg-Eppendorf (Germany), and colleagues randomized 331 patients with moderate to severe chronic plaque psoriasis who weighed 90 kg or more to receive
