Galderma Receives Filing Acceptances for Nemolizumab in Prurigo Nodularis and AD in Four Additional Countries

Galderma  has received filing acceptances for nemolizumab for the treatment of patients with prurigo nodularis and for adolescents and adults with moderate-to-severe atopic dermatitis (AD) in Australia, Singapore, Switzerland, and the United Kingdom, whose regulatory authorities are members of the Access Consortium. An approval decision is expected from the consortium next year.

Nemolizumab is a therapy specifically inhibiting IL-31 signaling to provide relief from itch.^1-7

According to Galderma, the Access Consortium is a collaborative initiative comprised of regulatory authorities which work together to address shared challenges, sharing knowledge and promoting greater collaboration to make regulatory systems more efficient.⁸ 

These acceptances are in addition to those received from the FDA and European Medicines Agency (EMA) for nemolizumab for the treatment of prurigo nodularis and atopic dermatitis in February 2024. Nemolizumab was also granted Breakthrough Therapy designation by the FDA in December 2019 for the treatment of pruritus associated with prurigo nodularis, a status reconfirmed in March 2023. The FDA subsequently granted nemolizumab 'Priority Review' for the treatment of prurigo nodularis; its decisions on prurigo nodularis and atopic dermatitis are anticipated this year. Further submissions to regulatory authorities in additional countries are ongoing.

The regulatory submissions of nemolizumab in prurigo nodularis are based on data from the phase 3 OLYMPIA clinical trial program, which evaluated the efficacy and safety of nemolizumab administered subcutaneously every 4 weeks in patients with prurigo nodularis.^9,10 Both trials in the OLYMPIA program met all primary and key secondary endpoints. Results demonstrated nemolizumab’s ability to rapidly improve itch, clear skin nodules and reduce sleep disturbance, with sustained improvements for up to one year.^11-13

The regulatory submissions of nemolizumab in atopic dermatitis are based on data from the phase 3 ARCADIA clinical trial program, which evaluated the efficacy and safety of nemolizumab administered subcutaneously every 4 weeks in adolescents and adults with moderate-to-severe atopic dermatitis.^14,15 Both trials in the ARCADIA program met all primary and key secondary endpoints. Results showed that nemolizumab clinically improved skin lesions and rapidly improved itch and sleep disturbance.¹⁶
