Biofrontera provides clinical development updates

Leverkusen, Germany, February 19, 2020 - Biofrontera AG (NASDAQ: BFRA; Frankfurt Stock Exchange: B8F) (the "Company"), an international biopharmaceutical company, today provides an update on its clinical developments.

On February 3, 2020, the Company announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) issued a positive opinion with respect to our submission for the Ameluz^(R) label extension for the treatment of actinic keratosis (AK) on the extremities and trunk/neck. In addition, the results of the follow-up phase of the clinical comparison study for daylight PDT with Ameluz^(R) and Metvix^(R) will be included in the product information (SmPC). Based on the positive opinion received from the CHMP, the Company anticipates that the European Commission will issue formal approval towards the end of the first quarter of 2020.

Biofrontera has also entered into discussions with the U.S. Food and Drug Administration (FDA) for approval in the U.S. of a label extension to include the treatment of AK on the extremities and trunk/neck. The FDA provided positive and constructive feedback requesting additional clinical trials in order to approve expanded indications for Ameluz^(R) on additional areas of the body. The study protocol is currently being prepared for review by the FDA and commencement of patient recruitment is planned for the second half of 2020.

In addition, after consultation with the FDA, Biofrontera has initiated a pharmacokinetics study (PK study) testing the safety of PDT with three tubes of Ameluz^(R). The purpose of this phase I study is to obtain pharmacokinetic profiles after Ameluz^(R)-PDT in subjects with actinic keratosis in an expanded treatment field located on the face/scalp or in the periphery. Furthermore, subjects' safety and tolerability during and after treatment will be assessed. The program provides for patient recruitment to last 3-5 months and for completion of this phase I study to be in the third quarter of 2020. The data from this study is expected to establish a basis to obtain coverage and reimbursement approval by governments, insurance companies and other third-party payors for the use of several tubes of Ameluz^(R) in conjunction with a newly developed lamp for PDT of larger peripheral body regions.

Biofrontera is currently working to develop a new PDT lamp, the "BF-RhodoLED-XL", which would allow the use of Ameluz^(R) on larger surfaces of the body. The schedule provides for submission of the application with the FDA in the second half of 2020.

With respect to the letter of intent between Biofrontera and Maruho Co. Ltd. regarding a possible indication expansion of Ameluz^(R) for acne as well as the expansion of commercializing Ameluz^(R) into parts of Asia and Oceania (see ad hoc-release on March 19, 2019), Biofrontera has prepared a development plan for the indication extension of Ameluz^(R) to acne and requested FDA to comment on the plan. FDA has in the meantime provided feedback regarding the design of the required clinical trials, such that the trial program is ready to be initiated shortly.
