WOBURN, Mass., Jan. 08, 2025 (GLOBE NEWSWIRE) -- Biofrontera Inc. (Nasdaq: BFRI) (“Biofrontera” or the “Company”), a biopharmaceutical company specializing in the development and commercialization of photodynamic therapy (PDT), today announced that a key milestone in its Phase 3 study of the use of Ameluz and RhodoLED PDT in the treatment of sBCC (ALA-BCC-CT013) was met with the last patient completing the 1 year follow-up visit in December of 2024. The double-blind, randomized, placebo-controlled, multi-center study evaluated safety and efficacy in 187 patients with one or more clinically and histologically confirmed superficial BCCs. They each received one cycle of two PDT treatments (either Ameluz® -PDT or placebo-PDT) 1-2 weeks apart. Lesions that were not completely resolved after 3 months were retreated. The FDA has advised Biofrontera to submit the sNDA with one-year follow-up data. While 1-year data will support the FDA submission, the superficial BCC lesions will in total be followed up for five years. Long-term follow-up studies are often required by the FDA for dermatology product submissions, in particular for skin cancers, and they are important in trials enrolling sBCC patients due to the risk of local recurrence, or subsequent additional skin cancer development. “We were delighted with the highly statistically significant results for the primary and secondary endpoints that we communicated last year”, stated Dr Hermann Luebbert, CEO and Chairman of Biofrontera Inc. “The completion of the 1-year follow-up is a crucial milestone in our path to an FDA submission in 2025 and potentially expanding our label to the treatment of a cutaneous malignancy. It demonstrates our continued investment in PDT and supports our vision of partnering with the dermatology community to improve patient care” he concluded. “We routinely use PDT in our institution for the treatment of actinic keratoses” commented Dr Shane Chapman, Chair of the Department of Dermatology at Dartmouth Hitchcock Medical Center and the Geisel School of Medicine at Dartmouth, and an investigator for ALA-BCC-CT013. “We were impressed with the results of the 12-week data and I look forward to being able to offer Ameluz-PDT as a treatment option for my patients with sBCC”. About Basal Cell Carcinoma BCC is the most common form of skin cancer and the most frequently occurring form of all cancers. In the U.S. alone, an estimated 3.6 million cases are diagnosed each year, a subset of which is superficial basal cell carcinoma. BCCs arise from abnormal, uncontrolled growth of basal cells at the bottom of the epidermis. They rarely spread beyond the original tumor site but, if untreated, can become locally invasive, grow wide and deep into the skin, and destroy skin, tissue and bone. 1 https://www.skincancer.org/skin-cancer-information/basal-cell-carcinoma/ About Biofrontera Inc.

Biofrontera started commercial distribution of the RhodoLED XL in June 2024 and has seen rapid uptake in the US market since launch.The RhodoLED XL is approved by the FDA in combination with Ameluz® (aminolevulinic acid hydrochloride) topical gel, 10% for photodynamic therapy (PDT) of actinic keratoses of mild-to-moderate severity on the face and scalp.Biofrontera’s RhodoLED XL and BF-RhodoLED lamps deliver red light energy using long-lasting light-emitting diode (LED) arrays. WOBURN, Mass., Dec. 23, 2024 (GLOBE NEWSWIRE) -- Biofrontera Inc. (Nasdaq: BFRI) (“Biofrontera” or the “Company”), a biopharmaceutical company specializing in the development and commercialization of photodynamic therapy (PDT), today announced that the 100th commercial RhodoLED® XL Lamp has now been installed in the US market. The RhodoLED XL was approved by the FDA for use in combination with Ameluz® in 2022 and was launched in June of this year. Since then, it has seen rapid adoption by offices who had previously used Ameluz and those who are new to the product, with 100 now being installed since launch. The main difference between the company’s existing BF-RhodoLED lamp and the new RhodoLED XL is the number of LED panels which allows a larger surface area to be illuminated during a single PDT treatment with Ameluz®. “We are delighted that the RhodoLED XL Lamp has had such an enthusiastic reaction from dermatologists who perform PDT, with more than 10% of offices using Ameluz already installing one” said Dr Hermann Luebbert, CEO and Chairman of Biofrontera Inc. “It is remarkable to have placed this many in such a short span of time post launch, and our customers have been very complimentary about the level of service we have delivered both in the lead up to installation, and with the training and support afterwards,” he continued. After a three-month evaluation of the RhodoLED XL, Dr. Aaron Hoover of Front Range Dermatology, Colorado was so impressed with its performance that his practice decided to purchase not one but two units, including the 100th installed RhodoLED XL lamp. “We were thoroughly impressed by the lamp’s robust yet elegant design, as well as its exceptional maneuverability and adjustability, which made it ideal for Photodynamic Therapy (PDT) treatments in our offices,” Dr. Hoover explained. “The larger illumination area has significantly increased our patient throughput while also enhancing the overall quality of care and patient experience.” Dr. Hoover also noted the high level of satisfaction among both staff and patients with the outcomes of using Ameluz PDT in conjunction with the RhodoLED XL. “Additionally, the Biofrontera team made the purchase and transition to the XL an entirely seamless process for us,” he added. “We were pleased to receive FDA approval for the use of up to 3 tubes of Ameluz® in one treatment in October of this year” stated Dr Luebbert. “With this capability and the larger illumination area of the RhodoLED XL our physicians can now treat a larger surface area on the face and scalp at one time which is efficient for the office and convenient for their patients” he concluded.

AKs typically appear on sun-exposed areas such as the face, bald scalp, arms or the back of the hands. In 2020, approximately 58 million people in the US were affected by AK and 13 million AK treatments were performed.21. https://www.skincancer.org/skin-cancer-information/basal-cell-carcinoma/2. https://www.skincancer.org/skin-cancer-information/actinic-keratosis/ About Biofrontera Inc.
