New Nemluvio (nemolizumab) post-hoc data from the ARCADIA long-term extension (LTE) study showed the majority of Week 16 responders maintained deep and lasting skin lesion and itch response for up to three years1
Additional long-term data further demonstrate Nemluvio’s consistent safety profile and sustained efficacy, including improvements in skin clearance, itch, sleep and quality of life in adults with prurigo nodularis up to 148 weeks, and people with atopic dermatitis aged 12 and older up to 152 weeks2,3
Phase II pediatric data will also be presented, with nemolizumab driving meaningful and sustained improvements in children aged 2-11 years with moderate-to-severe atopic dermatitis4
Alongside a product theatre exploring how targeted IL-31 treatment may impact patient outcomes, these findings reinforce Galderma's leadership in advancing treatment goals in atopic dermatitis and prurigo nodularis
