Expansion of indication for Ameluz^®: Biofrontera completes patient recruitment for Phase III Trial

● Enrollment of 50 patients at 6 sites in Germany completed

● Completion of the phase III trial for photodynamic therapy of actinic keratoses on the extremities and trunk/neck expected Q1 2019

● Filing for approval anticipated for Q3 2019

Leverkusen, Germany, July 26, 2018 – Biofrontera AG (NASDAQ: BFRA; Frankfurt Stock Exchange: B8F), an international biopharmaceutical company, has completed patient enrollment in another phase III trial with Ameluz^®. The study investigates the safety and efficacy of conventional photodynamic therapy (PDT) with Ameluz^® and the BF-RhodoLED^® lamp for the treatment of actinic keratoses (AK) on the extremities as well as the trunk and neck.

“Our goal is to entitle patients to treatment of actinic keratoses and field cancerization on the entire body,” explains Prof. Dr. Hermann Lübbert, CEO of Biofrontera: “Patients with actinic keratoses on their face and scalp, most likely have other severely affected areas of the body that are exposed to the sun, such as the hands, cleavage and neckline. Following successful approval, Ameluz^® would be the only PDT drug in Europe and the USA that can be used to treat actinic keratoses of all degrees of severity on the extremities, trunk and neck. The study is therefore another important milestone in increasing the competitiveness of Ameluz^® in both Europe and the USA”.

The multi-center, randomized, double-blind, intra-individual study included 50 patients at six study sites in Germany. Each patient had four to ten AK lesions in comparable areas on the right and left side of the extremities and/or trunk/neck. Mild, moderate and severe actinic keratoses are treated with one or, if required, two PDTs. The last assessment of the patients will take place three months after the last PDT. The clinical phase of the study is followed by a follow-up phase of twelve months after the last PDT. The results of the clinical phase are expected in the first quarter of 2019. Applications for marketing authorization extensions are to be submitted to the European Medicines Agency (EMA) and the US Food and Drug Administration (FDA) by the third quarter of 2019.

Each patient in the trial will be treated with Ameluz^®-PDT on one side and a placebo-PDT on the other side of the extremities or trunk/neck. The assignment of the sides is random. The primary endpoint of the study is efficacy defined as complete lesion clearance rate per patient’s side. In addition, safety and secondary efficacy parameters are evaluated.

Actinic keratoses are changes of the skin that manifest themselves as non-healing redness with a rough surface on typical sunlight-exposed skin areas. They mainly occur in people over 50. The main risk factor for the development of actinic keratoses is long-term exposure to the sun, whether at work or during leisure activities. Actinic keratoses can develop into squamous cell carcinoma, the second most common, potentially malignant skin tumor, and thus has to be treated rigorously. The number of annual treatments of actinic keratoses is estimated at over 12 million In the USA alone, and at over 2 million in the EU.
