Dupixent Wins Two NMPA Approvals in China – First Biologic for Bullous Pemphigoid and Pediatric Asthma Expansion

Dupixent Wins Two NMPA Approvals in China – First Biologic for Bullous Pemphigoid and Pediatric Asthma Expansion

Sanofi (NASDAQ: SNY) announced that Dupixent (dupilumab) has been approved by China’s National Medical Products Administration (NMPA) for two new indications: bullous pemphigoid (BP) in adults and maintenance treatment of asthma in children aged 6 and above. The approvals establish Dupixent as China’s first and only targeted biologic for BP and the first anti‑IL‑4Rα antibody covering pediatric asthma patients ≥ 6 years, expanding access to breakthrough therapy for underserved patient populations.

Regulatory Milestones

IndicationPatient PopulationSignificance
Bullous pemphigoid (BP)Adult patientsFirst and only targeted biologic approved for BP in China
Asthma maintenanceChildren aged ≥ 6 yearsFirst anti‑IL‑4Rα antibody covering pediatric asthma ≥ 6 in China

Disease Context

DiseaseCurrent ChallengeDupixent Value Proposition
Bullous pemphigoid (BP)Chronic autoimmune blistering disease; glucocorticoids/immunosuppressants cause significant side effects in elderly patientsSteroid‑sparing targeted therapy; improved safety profile
Pediatric asthmaCommon chronic respiratory disease; overall control levels in China remain unsatisfactoryFirst biologic maintenance option for children ≥ 6; addresses uncontrolled disease

Strategic Implications

  • BP Market Creation: As the first approved biologic for bullous pemphigoid in China, Dupixent establishes a new treatment category in an autoimmune disease with no prior targeted therapies, capturing significant unmet need in the elderly population.
  • Pediatric Asthma Leadership: The ≥ 6 years asthma approval fills a critical gap in China’s pediatric respiratory care, where biologic options were previously limited to adults—positioning Dupixent as the standard‑of‑care for severe pediatric asthma.
  • Label Expansion Momentum: These two NMPA approvals add to Dupixent’s 10+ global indications, reinforcing its position as the leading biologic for type 2 inflammatory diseases across all age groups and organ systems.
  • China Market Growth: With 60+ million asthma patients and rising autoimmune disease recognition, China represents a high‑growth market for Dupixent; these approvals expand addressable population by millions of patients.

Market Context

FactorImpact
BP Prevalence (China)Estimated 50,000–100,000+ patients; predominantly elderly; high steroid‑related morbidity
Pediatric Asthma (China)~ 10 million+ children affected; biologic penetration < 5% vs. 15–20% in US/EU—significant expansion opportunity
Dupixent Revenue (China)Growing contribution to global > $10 billion franchise; NMPA approvals support continued double‑digit growth
Competitive MoatFirst‑mover advantage in BP and pediatric asthma creates barriers to entry for emerging IL‑4/IL‑13 competitors
