INDUSTRY SHIFTS & MARKET DYNAMICS

Pemphigus vulgaris causes painful blisters and erosions affecting the skin and mucous membranes, often requiring prolonged treatment and specialist supervision. Greater diagnostic awareness among dermatologists and improved testing for disease-associated antibodies are helping identify patients who need treatment. Corticosteroids remain an important treatment option for controlling active disease, while immunosuppressive medicines such as azathioprine and mycophenolate mofetil can help manage disease activity and reduce reliance on long-term steroid treatment. Fact.MR estimates that corticosteroids will account for 48% of the product segment in 2026.

Biologic therapies are reshaping treatment strategies, particularly for patients with moderate-to-severe disease. Rituximab, which targets B cells involved in antibody production, has become an important option in treatment protocols. Its expanding clinical use is shifting part of the market toward targeted therapies with higher per-patient treatment costs. Intravenous immunoglobulin therapy also serves selected patients, including those with difficult-to-control disease. The emergence of biosimilar products may improve affordability and broaden access in markets where treatment costs remain a barrier.

Despite these developments, the market faces challenges related to the high cost of advanced therapies, differences in healthcare access, and regulatory timelines for new treatments. Diagnosis and treatment can be delayed when symptoms are initially mistaken for other skin or oral conditions. Access to specialist dermatology services and biologic medicines also varies between countries. Pharmaceutical companies that support clinical education, evidence-based prescribing, and affordable access strategies may be better positioned to serve this specialized market.

REGIONAL MARKET SUMMARY

Fact.MR projects the following country-level growth rates for the 2026–2036 period:

India is projected to record the fastest growth among the highlighted markets, at a CAGR of 9.5%, followed by China at 9.2%. Japan is expected to expand at 8.8%, while the United States and Germany are forecast to register CAGRs of 7.9% and 7.4%, respectively. These forecasts reflect differences in treatment access, healthcare infrastructure, diagnostic capabilities, and adoption of newer therapies.

ANALYST INSIGHTS

“The pemphigus vulgaris treatment market is being transformed by the shift from corticosteroid-dependent management to rituximab-based therapy. Clinical evidence establishing rituximab as first-line treatment for moderate-to-severe disease is changing prescribing patterns from steroid-centric suppression toward targeted B-cell depletion that achieves deeper and more durable remissions. Companies with established anti-CD20 biologic platforms and dermatology specialist relationships are capturing a growing share of the treatment value. The development of neonatal Fc receptor inhibitors and other targeted biologics is expected to further expand the treatment option portfolio,” stated Shambhu Nath Jha, Principal Consultant at Fact.MR.
