Why is Corticosteroids Segment Acquiring the Largest Share?

On the basis of product type, the corticosteroids segment is projected to account for the largest Prurigo Nodularis Therapeutics Market share of 37.2% in 2026. The segment’s growth is owing to the its entrenched role as first-line topical and intralesional therapy for reducing inflammation, flattening nodules, and interrupting the itch-scratch cycle before patients move to biologics, especially in mild-to-moderate or localized disease managed by dermatologists.

NIH’s NCBI Bookshelf lists class I topical corticosteroids as suggested first-line therapy, with clobetasol 0.05% used under occlusion for 2–4 weeks, while intralesional triamcinolone 10–20 mg/mL is reported to flatten lesions and relieve pruritus. In FDA-reviewed OLYMPIA studies, enrolled PN patients had at least 20 nodular lesions and severe itch score ≥7/10, showing the high symptom burden that sustains prescription topical use.

On the basis of Distribution Channel, the retail pharmacies segment lead with a major 42.1% share in 2026. The growth is owing to the prurigo nodularis being treated mainly through outpatient dermatology prescriptions, repeat refills for topical corticosteroids, antihistamines, neuromodulators, and newer injectable biologics that patients continue after diagnosis.

FDA notes PN is a rare disease causing intensely itchy nodules and affecting approximately 87,000 U.S. adults per year, creating a steady chronic-prescription base rather than one-time hospital use. FDA also states Dupixent, the first FDA-approved PN therapy, is supplied as a single-dose supporting pharmacy-led dispensing and refill management.

Market Drivers

Rising Innovations in Targeted Biologics are Transforming the Prurigo Nodularis Therapeutics Industry in the U.S.

The U.S. prurigo nodularis therapeutics industry is shifting from symptomatic management toward targeted biologic therapies. Historically, the treatment relied on corticosteroids, antihistamines, capsaicin, phototherapy, and off-label immunomodulators. However, the FDA-approved biologics are changing treatment standards by directly targeting immune pathways involved in itch, inflammation, as well as nodule formation.

In August 2024, Galderma received the U.S. FDA approval for Nemluvio (nemolizumab), a pre-filled pen for adults with prurigo nodularis. The IL-31-targeting monoclonal antibody showed substantial improvements in itch, skin nodules, and sleep disturbance in Phase III OLYMPIA trials versus placebo. This development is expected to strengthen the adoption of targeted injectable biologics in dermatology specialists, hospital outpatient departments, specialty pharmacies, and long-term PN care pathways.

IL-31 Receptor Blockade: A Major Breakthrough in Prurigo Nodularis Therapeutics Market

IL-31 receptor blockade is a major breakthrough in the Prurigo Nodularis Therapeutics Market. It targets one of the central biologic pathways involved in chronic itch. Traditional PN therapy has relied heavily on topical corticosteroids, antihistamines, phototherapy, immunosuppressants, and off-label systemic agents. However, many patients with moderate-to-severe disease remain uncontrolled because PN is driven by complex neuroimmune signaling. IL-31 receptor inhibition addresses this unmet need by directly reducing itch signaling and helping reduce scratching, lesion worsening, and sleep disruption.

Nemolizumab is one of the most important recent advances in this area. According to Galderma, in the OLYMPIA 1 and OLYMPIA 2 trials, 56% and 49% of Nemluvio-treated patients achieved at least a four-point reduction in itch intensity at Week 16, compared with 16% in placebo groups. Galderma also reported that around 41% of Nemluvio-treated patients achieved this itch reduction by Week 4, thereby demonstrating the rapid clinical benefit. These results position IL-31 receptor blockade as a differentiated approach within targeted PN therapy.

In February 2025, Galderma received the European Commission approval for Nemluvio (nemolizumab) to treat adults with moderate-to-severe prurigo nodularis. The IL-31 receptor alpha-targeting biologic showed significant improvements in itch, skin lesions, and sleep disturbance in Phase III OLYMPIA trials.

Market Report Scope 

Analyst Opinion

• The Prurigo Nodularis Therapeutics Market growth is not only supported by new drug launches but by structural unmet need in chronic itch management. According to Regeneron and Sanofi, about 75,000 adults in the U.S. with PN were most in need of new treatment options when Dupixent was approved. This indicates that demand will remain resilient because moderate-to-severe PN patients often require long-term specialist care.
• Targeted biologics are expected to redefine the treatment algorithm. According to Galderma, Nemluvio delivered clinically meaningful itch reduction in 56% and 49% of treated patients at Week 16 across OLYMPIA 1 and 2, compared with 16% in placebo groups. This matters because therapies that reduce itch and sleep disturbance can support better adherence as well as premium pricing.
• North America will remain the revenue anchor, but Asia Pacific will offer faster volume expansion. According to WHO, the population aged 60 years and above is expected to rise to 1.4 billion by 2030 and 2.1 billion by 2050 globally. This demographic shift will support demand in Japan, China, India, and South Korea as diagnosis improves and biologic access expands.
