• LEO Pharma is seeking to expand the availability of Enstilar^® (LEO 90100) to China, as the company announces the submission of a New Drug Application (NDA) to the National Medical Products Administration (NMPA).

NOT INTENDED FOR DISTRIBUTION IN THE UK

LEO Pharma A/S, a global leader in medical dermatology, has today announced its submission of a New Drug Application (NDA) to the National Medical Products Administration (NMPA) for Enstilar^® (LEO 90100) to treat adult patients living with plaque psoriasis.

Following a week of significant LEO Pharma treatment and data milestones in the EU and the U.S., today’s news of the NDA submission in China is the latest example of LEO Pharma’s global strategy in action across medical dermatology. If approved, China would join 50 other markets in the world to be approved to bring Enstilar to patients, and would be the largest country to date.

Enstilar^®, a calcipotriol/betamethasone cutaneous foam, is an improved formulation of Daivobet^® ointment, which is one of the current standard treatment options in China for adults living with plaque psoriasis.⁴ Both Daivobet ointment and Enstilar are LEO Pharma products.

“LEO Pharma strives to enhance patient care and elevate quality of life for those living with complex skin conditions like plaque psoriasis,” said Byron Yin, General Manager for LEO Pharma, China. “Today’s submission is a crucial step towards offering a much-needed new treatment option in our region, in addition to the existing portfolio offering from LEO Pharma China.”

“Today’s submission of our NDA for Enstilar is a testament to LEO Pharma’s truly global outlook and ambition in advancing dermatology, following on from a week of milestones across both the EU and U.S.” said Becki Morison, Executive Vice President, Global Product Strategy & International Operations for LEO Pharma. “China is a key market for LEO Pharma, with dermatology growing rapidly in the country and our revenue steadily increasing through a strong performance from our team. We will continue to leverage our extensive dermatology expertise to enhance the treatments we can provide in the region, unwavering in our goal to provide support to those in China that need it most.”

The NDA submission is supported by results from a phase 3 trial comparing the efficacy and safety of a once daily application with Enstilar and Daivobet ointment after 4 weeks of treatment in adult Chinese subjects with stable plaque psoriasis (N=604).^1,2 The trial achieved its primary and secondary endpoints, with Enstilar demonstrating superiority to Daivobet ointment.²

“The trial showed the potential that Enstilar has to improve the quality of life for millions of Chinese patients living with plaque psoriasis,” said Professor Zhang Jianzhong from Peking University People's Hospital, lead investigator of the phase 3 Enstilar trial. “Through today’s milestone, we take a step towards new treatment options for the millions that live with plaque psoriasis in the near future.”

Following the Enstilar submission, the Centre for Drug Evaluation (CDE) will validate the filing, before the full evaluation of the NDA is conducted by the CDE. The regulatory review process is expected to conclude in the first half of 2026.
