Leverkusen, Germany (pta034/08.06.2022/14:15 UTC+2)

Biofrontera AG (ISIN: DE0006046113), an international biopharmaceutical company, announces that its license partner and marketing authorization holder in Switzerland, Louis Widmer SA, has successfully obtained an extension of its marketing authorization for the treatment of actinic keratosis in extremities, trunk and neck with Ameluz®.

The use of Ameluz® PDT for actinic keratosis also in the body periphery, which has already been approved by the European Medicines Agency, EMA, since 2020, was submitted separately by Louis Widmer to the Swiss Medicines Authority, Swissmedic. Louis Widmer had adapted the European marketing authorization documents and submitted an application to the authority for an extension of the marketing authorization. Following the approval that has now been granted, the Swiss product label of Ameluz® covers the same range of applications that has already been approved in the countries of the European Union and the United Kingdom since 2020.

An exclusive licensing agreement for the marketing of Ameluz® and BF-RhodoLED® in Switzerland and Liechtenstein has been in existence between Biofrontera and Louis Widmer since 2014, under which Louis Widmer began marketing Ameluz® in 2016, following the granting of approval by Swissmedic. In addition to the expansion to include the treatment of actinic keratosis on the trunk, neck, and extremities, Louis Widmer had previously added the use of Ameluz® in daylight, field cancer, and superficial inoperable forms of basal cell carcinoma to its Swiss approval.
