Brodalumab in The Treatment of Moderate-To-Severe Psoriasis in Patients Refractory to Anti-Interleukin-17A Therapies: Evaluation of Secondary Endpoints

Background: Brodalumab is an interleukin-17 receptor A antagonist approved for the treatment of moderate-to-severe plaque psoriasis. Our prior publication reported significant disease improvement with brodalumab in psoriasis patients who had previously failed treatment with an anti-IL-17A agent. Methods: We conducted an Institutional Review Board (IRB)-approved open-label study of a total of 39 subjects enrolled at 3 sites with moderate-to-severe psoriasis. All patients previously failed treatment with an IL-17A agent. Subjects received brodalumab 210 mg via subcutaneous injection at weeks 0, 1, and 2, followed by 210 mg every 2 weeks, up to week 16. Subjects were evaluated monthly for improvement in PASI and sPGA. Results: Of the baseline comorbidities assessed, the only statistically significant difference between responders and non-responders was the presence of higher weight/BMI in non-responders in the AO dataset; this trend disappeared in the NRI dataset. Of the patients that dropped out of the trial early, 3 of the 5 had PASI improvements of >60%. A rapid onset to disease improvement was seen in the trial. Conclusion: These results indicate that brodalumab may be a good treatment choice for psoriasis patients, including those with severe disease and/or underlying comorbidities.
