LEO Pharma expands its psoriasis portfolio in China with NMPA approval of Enstilar®

BALLERUP, Denmark, April 17, 2026 - LEO Pharma A/S, a global leader in medical dermatology, today announced that China's National Medical Products Administration (NMPA) has approved Enstilar® (calcipotriene/betamethasone dipropionate) to treat adult patients in China living with plaque psoriasis.

The approval means that the estimated 6.5 million people in China suffering from the disease will soon have access to a new treatment option.¹

Enstilar is a foam formulation, which allows the medication to be applied in an aerated form that spreads easily over the skin, including hair-bearing areas, and can facilitate even distribution of the active ingredients with a rapid relief achieved in clinical studies.4

“China is the largest market in terms of patient numbers and represents an important pillar in LEO Pharma’s long-term growth strategy,” said Frederik Kier, EVP, International Operations, LEO Pharma. “The Chinese market is characterized by a growing focus on innovative dermatology treatments. With the introduction of Enstilar, we are proud to broaden our portfolio and offer millions of patients a new treatment option while continuing to invest in innovation and strengthening our commercial presence in one of the world’s most significant dermatology markets.”

LEO Pharma is a global market leader in topical treatments for psoriasis, with close to three million patients worldwide using its products within this disease.⁵ With the approval of Enstilar in China, the company strengthens its position in the largest single market measured by patient numbers. China joins more than 50 other markets where Enstilar is approved, and the country’s large patient population, evolving healthcare landscape and increasing access to innovative treatments provide a strong foundation for the introduction of both established and future dermatology therapies.

“The NMPA approval represents an important milestone for LEO Pharma in China,” said Byron Yin, General Manager, LEO Pharma China. “For patients living with plaque psoriasis, it means access to a treatment that has been widely adopted in other markets and has become an important part of clinical practice. This approval not only expands treatment options for patients in China, but also marks a key step in building the foundation for the broader portfolio of dermatology treatments we plan to bring to the Chinese market in the near future.”

The NMPA-approval is supported by results from a phase 3 trial comparing the efficacy and safety of a once daily application with Enstilar foam and Daivobet® (calcipotriene/betamethasone) ointment after 4 weeks of treatment in adult Chinese subjects with stable plaque psoriasis (N=604).^2,3 The trial achieved its primary and secondary endpoints, with Enstilar demonstrating superiority to Daivobet ointment. ^2,3

Following the approval by the NMPA, the launch of Enstilar in China is planned for later this year.

About Psoriasis

Psoriasis is a chronic, systemic inflammatory disease that primarily affects the skin in 125 million people worldwide.^9,10 Psoriasis is the result of skin barrier cell proliferation and the activation of cytokines (a family of proteins involved in immune responses) that cause inflammation.¹¹ About 80% to 90% of patients are affected by plaque psoriasis, the most common clinical form of psoriasis.¹² The symptoms of plaque psoriasis are itchy or painful raised scaly and inflamed plaques. Plaques may appear anywhere on the body, but often appear on the scalp, knees, elbows and torso.¹²
