“Prurigo nodularis is a miserable disease and treatment options are desperately needed that offer early and durable relief by both reducing the relentless itching associated with the disease and allowing for healing of the painful lesions that are the hallmark of PN,” said
The randomized, double-blind, placebo-controlled, parallel group study is evaluating the efficacy and safety profile of 2 dose levels of barzolvolimab compared to placebo in approximately 120 patients with moderate to severe PN who had inadequate response to prescription topical medications, or for whom topical medications are medically inadvisable (such as concerns for safety), including patients who received prior biologics. Patients will be randomly assigned on a 1:1:1 ratio to receive barzolvolimab injections of 150 mg Q4W after an initial loading dose of 450 mg, 300 mg Q4W after an initial loading dose of 450 mg, or placebo during a 24‑week treatment phase. Participants will then enter a follow-up phase with no study treatment for an additional 16 weeks through week 40. The primary objective of this study is to evaluate the clinical effect of barzolvolimab, compared to placebo, on itch response as measured by the proportion of participants with ≥ 4-point improvement in the worst intensity itch per a numeric rating scale (WI-NRS). Secondary objectives include but are not limited to additional measures of itch response from baseline compared to different timepoints, the assessment of skin lesions as measured by the Investigator Global Assessment (IGA), QoL outcomes and safety. The study will include approximately 50 clinical trial centers worldwide, including

About Prurigo Nodularis (PN)
PN is a chronic skin disease that causes hard, intensely itchy lumps/nodules to form on the skin. The itching (pruritus) can be intense, causing people to scratch themselves to the point of bleeding or pain, which can form lesions and perpetuate the disease cycle. With limited treatment options available, PN is also associated with significant impact on quality of life including sleep disturbance, psychological distress, social isolation, anxiety and depression. Mast cells are believed to play an important role in amplifying chronic itch and neuroinflammation, including in PN where mast cells are associated with pruritic sensory neurons in PN lesions.
About Barzolvolimab
Barzolvolimab is a humanized monoclonal antibody that binds the receptor tyrosine kinase KIT with high specificity and potently inhibits its activity. KIT is expressed in a variety of cells, including mast cells, which mediate inflammatory responses such as hypersensitivity and allergic reactions. KIT signaling controls the differentiation, tissue recruitment, survival and activity of mast cells. In certain inflammatory diseases, such as chronic urticaria, mast cell activation plays a central role in the onset and progression of the disease. Barzolvolimab is currently being studied in chronic spontaneous urticaria (CSU), chronic inducible urticaria (CIndU), prurigo nodularis (PN) and eosinophilic esophagitis (EOE) with additional indications planned for the future, including atopic dermatitis (AD).
