Pemphigus Vulgaris Market
- In the total Pemphigus Vulgaris market size in the 7MM, the United States accounted for the highest Pemphigus Vulgaris market share, i.e. more than 75% in 2023, followed by Germany.
- According to the National Organization for Rare Disorders (2023), pemphigus vulgaris (PV) is a severe, rare autoimmune disorder marked by painful blisters and erosions on the skin and mucous membranes, including the mouth, throat, and sometimes genital areas. It occurs when the immune system mistakenly attacks desmogleins, proteins essential for cell adhesion in the epidermis, leading to cell separation and blister formation.
- Blisters associated with pemphigus are typically flaccid and fragile, forming mainly on areas like the scalp, face, chest, and back, and particularly within mucous membranes such as the mouth. They rupture easily, often resulting in painful, open sores that are slow to heal. Unlike pemphigoid, which affects deeper skin layers and produces firmer, more resilient blisters, pemphigus involves more superficial skin layers, resulting in delicate, easily ruptured blisters.
- In Pemphigus Vulgaris, autoantibodies specifically target desmogleins (proteins crucial for cell-to-cell adhesion) in the epidermis. This leads to the breakdown of cellular connections, resulting in the separation of skin cells (acantholysis) and subsequent blister formation.
- Diagnosing Pemphigus Vulgaris involves differentiating it from other blistering diseases, such as bullous pemphigoid or other types of pemphigus, through biopsy and antibody testing, particularly identifying anti-desmoglein antibodies.
- Treatment focuses on controlling the autoimmune activity that causes blistering, primarily through corticosteroids, immunosuppressants like azathioprine or mycophenolate, and biologic therapy with Rituximab, which targets B-cells responsible for autoantibody production. Currently, RITUXAN (rituximab) is the only FDA-approved therapy for the treatment of pemphigus vulgaris; it has become an effective option for achieving remission, especially in moderate-to-severe cases, often allowing for lower corticosteroid doses.
- Additional supportive treatments include antibiotics for infection prevention, pain management for oral lesions, and proper wound care to aid healing. Despite a tendency for relapse, close monitoring and these therapies help many patients manage PV, and new-targeted treatments are under investigation to improve outcomes further.
- CABA-201, a CD19-CAR T therapy developed by Cabaletta Bio, is in Phase I/II development for treating PV.
- In 2023, the United States accounted for the highest diagnosed prevalent cases of Pemphigus Vulgaris followed by Germany.
- In the 7MM, Females reported more cases than males for Pemphigus Vulgaris.
- In the United States, individuals of the 60-69 year age group reported the highest number of pemphigus Vulgaris cases.

Key Factors Driving Pemphigus Vulgaris Market
Rising Pemphigus Vulgaris Prevalence in Aging Populations
In the 7MM, Pemphigus Vulgaris cases continue to rise, with the United States accounting for nearly 40K cases in 2023, over 75% of the total market share. Prevalence is notably higher among females, and the highest number of cases is reported in individuals aged 60–69 years. By 2034, diagnosed cases are projected to increase further, reflecting both demographic shifts and improved diagnostic awareness.
Launch of Emerging Biologic and Cell-Based PV Therapies
RITUXAN (rituximab) remains the only FDA-approved therapy for Pemphigus Vulgaris, serving as a cornerstone in moderate-to-severe cases. However, the pipeline is advancing with innovative therapies, most notably Cabaletta Bio’s CABA-201, a CD19-CAR T-cell therapy currently in Phase I/II clinical development. Designed to transiently deplete CD19-positive B cells, CABA-201 aims to “reset” the immune system and deliver long-term remission with a single infusion. Additional approaches under investigation include novel B-cell–directed antibodies and antigen-specific cell therapies.
Expanding R&D and Clinical Trial Investments in PV
Over a dozen pharmaceutical and biotech companies, including Cabaletta Bio, Roche, Sanofi, Novartis, and others, are investing in next-generation Pemphigus Vulgaris therapies. Multiple RESET Phase I/II trials are ongoing for CABA-201 across autoimmune indications, with pemphigus cohorts advancing in parallel. The orphan-drug designation previously granted to DSG3-CAART underscores the increasing regulatory and commercial interest in targeted PV therapies.
Advances in Diagnostics and Early Disease Management
Improved diagnostic accuracy, through antibody testing for anti-desmoglein 1 and 3 and confirmatory skin biopsies, has enabled more precise disease differentiation from related blistering disorders, such as bullous pemphigoid. Early detection now accounts for a growing share of identified cases, allowing timely intervention with corticosteroids, immunosuppressants, and biologics. This shift toward earlier diagnosis and personalized therapy has already begun to improve outcomes and reduce relapse frequency.

Pemphigus Vulgaris Treatment Market
Pemphigus Vulgaris Overview
Pemphigus is a rare autoimmune blistering disorder that affects the outermost layer of the skin (epidermis) and mucous membranes. It is characterized by the formation of fragile blisters and lesions that rupture easily, leaving painful sores. This condition arises when the immune system mistakenly produces autoantibodies—particularly against proteins called desmoglein 1 and desmoglein 3, which are essential for maintaining the adhesion between skin cells. The disruption of these cellular junctions leads to a loss of skin integrity, causing the skin cells to separate, a process known as acantholysis. As a result, fluid accumulates between the skin layers, leading to the formation of blisters.

Pemphigus Vulgaris (PV) Diagnosis
The current diagnosis of Pemphigus Vulgaris involves a combination of clinical assessment, histopathological examination, and advanced immunological techniques such as direct and indirect immunofluorescence and ELISA. The diagnosis of Pemphigus Vulgaris should be suspected in any patient with mucocutaneous erosions or blisters. The oral mucosa is the first site of involvement in the majority of cases, and Pemphigus Vulgaris may remain confined to the mucosal surfaces or extend to involve the skin (average lag period of 4 months).
Further details related to country-based variations are provided in the report…
Pemphigus Vulgaris Treatment
The treatment of Pemphigus Vulgaris has significantly improved with the use of systemic corticosteroids, which reduced the disease's mortality rate by 60%. These steroids remain the first-line therapy, particularly for mild cases, though they require careful monitoring due to side effects like infections and osteoporosis. For moderate-to-severe PV, rituximab, an anti-CD20 monoclonal antibody, is commonly used in combination with corticosteroids, helping to deplete B-cells responsible for producing the autoantibodies that attack the skin. Steroid-sparing agents like azathioprine and mycophenolate mofetil (MMF) are also used to reduce steroid dependence and minimize side effects. For refractory cases, treatments such as IVIg and cyclophosphamide may be considered. While these therapies have improved outcomes, Pemphigus Vulgaris treatment remains complex, requiring ongoing management to balance efficacy and side effects.
