With this approval, Ameluz becomes the first and only PDT drug approved by the FDA for the treatment of a skin cancer, and the only topical PDT in the United States indicated to treat both a pre-cancerous skin condition, actinic keratosis (AK), and a skin cancer. The sBCC indication expands the addressable market for Ameluz and strengthens its position in medical dermatology. This label expansion also furthers Biofrontera's strategy of broadening the clinical utility of its Red-Light PDT platform. Hermann Luebbert, Chief Executive Officer and Chairman of Biofrontera, stated: "FDA approval of Ameluz for superficial basal cell carcinoma is a defining milestone for Biofrontera. Ameluz is now the first and only photodynamic therapy approved in the United States to treat a skin cancer, which sets our platform apart in medical dermatology and gives dermatologists an effective, non-surgical option for a very common tumor. This approval reflects years of disciplined investment in the clinical development of Ameluz, and the latest stage in the ongoing expansion of our PDT platform." He added "We are planning an official launch of the sBCC indication late in the fourth quarter of 2026 through the first quarter of 2027 with our existing commercial organization and installed lamp base. We believe the approval represents a further driver of long-term growth for our existing customers. It also gives new Dermatology practices a reason to purchase a RhodoLED lamp and begin to use Ameluz PDT, expanding our overall installed base." This new indication utilizes the same topical product (Ameluz) and the same red-light device as the Company’s AK indication, so our existing customers will be able to rapidly adopt this new treatment option.

Basal cell carcinoma (BCC) is the most common skin cancer in the United States, with approximately 3.6 million cases diagnosed annually, according to the Skin Cancer Foundation. Published estimates suggest that the superficial subtype accounts for approximately 15%-20% of BCC cases, or an estimated 540,000 to 720,000 sBCC cases annually in the U.S.2. Superficial BCC lesions can be up to several cm in diameter and are frequently located on the trunk and extremities and often present as multiple lesions, for which non-surgical, tissue-sparing treatment options are limited.

The approval is supported by a multicenter, randomized, double-blind, vehicle-controlled Phase 3 trial in 187 adults with histologically confirmed sBCC. The primary endpoint was a composite of both clinical and histological complete response of a main target lesion 12 weeks after the start of the last PDT cycle. This rigorous target was achieved in 66% of subjects treated with Ameluz PDT (95/145) compared with 5% of subjects treated with placebo-PDT (2/42). Histological clearance of the main target lesion was seen in 76% of Ameluz PDT treated patients versus 19% with Placebo-PDT, and 83% of Ameluz-treated subjects achieved complete clinical clearance of all target lesions compared with 21% for Placebo-PDT. The most common adverse reactions were application-site reactions consistent with the known safety profile of Ameluz PDT.

Dr. M. Shane Chapman, MBA, board certified dermatologist, Professor and Founding Chair, Department of Dermatology, Dartmouth Hitchcock Medical Center and the Dartmouth Geisel School of Medicine, and a key contributor to the Phase 3 study added "For many patients with superficial basal cell carcinoma — those with multiple lesions, lesions in cosmetically sensitive locations, or for whom surgery would not be preferred — treatment options have been limited. This FDA approval for Ameluz® and the RhodoLED gives us a rigorously studied, non-surgical option that we can deliver in our office. As someone who has worked with PDT for many years, I see this as a meaningful expansion in the use of this treatment."
