Biofrontera reports further positive results from the phase III trial with Ameluz for photodynamic therapy of actinic keratoses on the extremities and trunk/neck

Leverkusen, Germany, April 16, 2019 (GLOBE NEWSWIRE) -- Biofrontera AG (NASDAQ: BFRA; Frankfurt Stock Exchange: B8F) (the "Company"), an international biopharmaceutical company, today reports positive results for the secondary endpoints of its Phase III clinical trial evaluating the safety and efficacy of conventional photodynamic therapy (PDT) with Ameluz® in combination with the BF-RhodoLED® lamp for the treatment of actinic keratoses (AK) on the extremities or trunk/neck. Patients were treated with Ameluz® on one side of the body and with a placebo gel on the other side.

In line with the result for the primary endpoint of the study (see ad hoc report dated March 20, 2019), which showed a mean lesion clearance rate per patient's side of 86% for Ameluz® compared to 33% for placebo, significant superiority of Ameluz® was demonstrated for all secondary parameters investigated. Even if mild AKs were ignored and only moderate AKs were considered, mean lesion clearance rates per patient's side were 84% with Ameluz® compared to 27% with placebo. In patients treated on the extremities, mean lesion clearance rates per patient's side were also 84% with Ameluz® compared to 27% with placebo. Mean lesion clearance rates in the area trunk/neck were even higher. Furthermore, the comparison parameter "patient complete clearance" also emphasized the superiority of Ameluz®: 67% of the patients' sides were completely cleared 12 weeks after the last PDT compared to 12% of the placebo-treated sides. All of the results were statistically highly significant. Thus, all secondary endpoints also confirm the high superiority of Ameluz® over the control group.

"It is generally accepted in dermatology that actinic keratoses of the trunk and extremities are particularly difficult to treat. Once we have received the approval both in Europe and the U.S., our excellent results for the treatment of these body regions will make Ameluz® stand out even more compared to alternative forms of therapy," explained Prof. Dr. Hermann Lübbert, CEO of Biofrontera AG.

These results support the primary endpoint data for the applications to the European Medicines Agency (EMA) and U.S. Food and Drug Administration (FDA), which Biofrontera plans to submit during the third quarter of 2019.

The multi-center, randomized, double-blind, intra-individual study included 50 patients at six study sites in Germany, each with four to ten clinically confirmed AK lesions in comparable areas on the right and left side of the extremities and/or trunk/neck. Mild, moderate and severe actinic keratoses were treated with one or two PDT treatments. The final examination of the patients took place three months after the last PDT treatment. The clinical study phase is now followed by a follow-up phase of twelve months after the last PDT, in which recurrence rates and/or numbers of new AKs and skin tumors are determined.
