ZUG, Switzerland--(BUSINESS WIRE)--Galderma today announced that the U.S. Food and Drug Administration (FDA) has approved Nemluvio® (nemolizumab) as a pre-filled pen for subcutaneous injection for the treatment of adults with prurigo nodularis.1 Nemluvio was granted Breakthrough Therapy Designation in December 2019 and Priority Review in February 2024 by the U.S. FDA – a status reserved for medicines with the potential to significantly improve the treatment of serious conditions.

Prurigo nodularis is an underdiagnosed neuroimmune skin disease which is estimated to affect up to 181,000 people in the United States.7,8 This condition is characterized by several debilitating symptoms, including chronic itch, skin nodules covering large body areas, and poor sleep quality.5,9 Given the significant burden on patients, there is a need for alternative treatment options that may effectively relieve key signs and symptoms of the disease.10 Nemluvio specifically inhibits IL-31 cytokine signaling, which is known to drive itch and is involved in inflammation, altered epidermal differentiation, and fibrosis (hardening of skin tissue) in prurigo nodularis.1-3,11,12
