Dupixent’s Expanding Therapeutic Reach And Market Success In 2025
In 2025, Dupixent (dupilumab), developed by Sanofi and Regeneron, continues to solidify its position as a leading treatment for various inflammatory diseases.
Recent FDA approvals and impressive sales figures underscore its growing significance in the pharmaceutical landscape.
FDA Approves Dupixent For Chronic Spontaneous Urticaria
On April 18, 2025, the U.S. Food and Drug Administration (FDA) approved Dupixent for the treatment of chronic spontaneous urticaria (CSU) in patients aged 12 years and older. CSU is a skin condition characterized by itchy rashes and swelling beneath the skin.
This approval marks a significant milestone, especially after a previous FDA rejection in 2023 due to insufficient efficacy data.
With this new indication, Dupixent is now authorized to treat CSU alongside its existing uses for asthma, eczema, and chronic lung conditions. The eligible CSU patient population in the U.S. is estimated to exceed 300,000.
Strong Financial Performance Driven By Dupixent
Sanofi’s first-quarter financial results for 2025 highlight Dupixent’s substantial contribution to the company’s growth. The drug’s sales increased by 20.3% to €3.48 billion, significantly boosting Sanofi’s business operating income by 20.1% to €2.90 billion.
This performance surpassed analysts’ expectations and underscores Dupixent’s role as a key revenue driver. Despite global economic uncertainties, Sanofi maintains its full-year profit and sales forecasts, emphasizing its commitment to research and development investments to sustain growth.
European Approval For COPD Treatment
In July 2024, the European Union approved Dupixent for the treatment of chronic obstructive pulmonary disease (COPD), commonly known as ‘smoker’s lungs.
This approval was granted faster than in the United States, where the FDA postponed its review to September 27 to obtain additional efficacy data. COPD affects approximately 16 million adults in the U.S. and over 35 million people in Europe.
Sanofi estimates that around 300,000 patients in the U.S. could be eligible for this treatment. Dupixent’s approval for COPD adds to its portfolio of indications, further solidifying its position in the market.
Conclusion
Dupixent’s recent FDA approval for CSU, strong financial performance, and European approval for COPD treatment underscore its expanding impact in the pharmaceutical industry.
As Sanofi and Regeneron continue to explore new indications and invest in research and development, Dupixent is poised to remain a cornerstone in the treatment of various inflammatory diseases.
