Onychomycosis affects approximately 5.5%¹of the global population and accounts for 50% of all nail disorder consultations². It is an often persistent and difficult to treat condition with low rates of treatment success due to challenging long term adherance. The low binding affinity of efinaconazole topical to keratin, the main component of nails, allows high nail-penetrating properties supporting strong efficacy.

With the addition of this treatment, Almirall enhances its European medical dermatology portfolio and reaffirms its commitment to people living with skin infections and dermatologists by providing innovative therapeutic options that make a significant impact on their lives.

"At Almirall, we are dedicated to medical dermatology, andto addressing unmet needs of people living with skin conditions such as persistent and difficult to treat nail infections. The completion of the decentralized regulatory procedure for efinaconazole in Europe enables European countries to approve this advanced treatment option to support people with onychomycosis. Efinaconazole as a topical treatment is a valuable addition to our expanding onychomycosis portfolio and we are looking forward to being able to offer it to European dermatologists and their patients in the near future said Almirall Executive VP of R&D and CSO Dr. Karl Ziegelbauer.

In July 2021, Kaken and Almirall entered into a license and distribution agreement, granting Almirall the exclusive rights for the development and commercialization of this topical formulation in Europe.

The product has been marketed in Japan since 2014 under the trade name Clenafin. It has also been launched in the United States, Canada, Korea, Hong Kong, and Macau by Kaken Pharmaceutical's partner companies under the trade name Jublia

The successful completion of the decentralized procedure is the final step before national marketing authorizations can be granted by European countries. Work with the national regulatory authorities is now underway, and marketing authorizations are expected within H1 2025.
