Biofrontera : European Medicines Agency recommends indication expansion of Ameluz® for treatment of basal cell carcinoma (BCC)

Press Release European Medicines Agency recommends indication expansion of Ameluz® for treatment of basal cell carcinoma (BCC)

• Approval by the European Commission expected in the next few weeks
• Increased market potential for Ameluz® particularly in hospitals

Leverkusen, Germany, December 20, 2016 - Biofrontera AG (FSE: B8F), the specialist for the treatment of sun-induced skin cancer, today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has issued a positive opinion with respect to Biofrontera's submission for label extension for its topical pre- scription drug Ameluz®. The extended approval will include the treatment of superficial and/or nodular basal cell carcinoma unsuitable for surgical treatment due to possible treatment-re- lated morbidity and/or poor cosmetic outcome in adults. Based on the positive opinion, Bio- frontera anticipates that the European Commission will issue formal approval within the coming weeks, significantly expanding the European market opportunity for Ameluz®. This will greatly extend the market opportunity for Ameluz®.

The approval for BCC allows Biofrontera to increase its efforts in placing the medicine in hos- pitals, where BCC is treated more frequently than AK. Dermatologists are predominantly based in hospitals in many European healthcare systems, and the new indication will be most relevant for those markets.

BCCs are the most common invasive tumors in humans and account for 50-80% of all invasive skin cancers. Around 30% of all Caucasians develop at least one BCC in their lifetime, and cases are increasing rapidly worldwide due to elevated exposure to UV light. Surgical removal of BCCs is the most frequent treatment currently used, but this can result in clearly visible scarring. The treatment with photodynamic therapy (PDT) is an alternative particularly for thin BCCs, and gives rise to excellent cosmetic results.

As a prerequisite for the approval of BCC Biofrontera had conducted a pivotal phase III trial with a total of 278 patients. The trial was conducted under the clinical supervision of Prof. Colin Morton (UK) and Prof. Markus Szeimies (Germany) and was carried out at 27 clinical trial centers in the UK and Germany. The results of the trial have been available since January 2016 and formed the basis for the application for approval extension. Efficacy and safety of Ameluz® were compared with that of Metvix®, a medication already approved in the EU for the treatment of BCC. The results confirmed the company's positive expectations. Non-aggressive (superficial and nodular) BCCs with a thickness of up to 2 mm were included in the trial. Ame- luz® achieved the complete eradication of all BCCs in 93.4% of the patients, compared to 91.8% with Metvix®. There were greater differences in the case of thicker BCCs. With Ameluz®, 89.3% of the nodular carcinomas were completely removed, compared to only 78.6% with Metvix®. Additionally, after 12 months the recurrence rates were higher for Metvix® than for Ameluz® thereby increasing the distance between Ameluz® and Metvix®.

"We are very pleased with the CHMP's favourable review regarding the label extension for Ameluz®, another important validation of the qualities of Ameluz®," commented Prof. Dr. Her- mann Lübbert, CEO of Biofrontera. "We now look forward to the positive decision by the Euro- pean Commission, which will allow us to expand our sales and marketing efforts by promoting basal cell carcinomas throughout Europe together with our marketing partners. This represents another important milestone in our strategic efforts to expand the market penetration of Ame- luz® und to increase the product's revenue potential."
