Database locks for studies on actinic keratosis (AK) and acne vulgaris achieved on January 5, 2026
Data generated will support key regulatory milestones for Ameluz PDT in both indications
AK and acne are the two most commonly diagnosed skin disorders in the US¹

WOBURN, Mass., Jan. 08, 2026 (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 the successful database lock of two clinical studies evaluating Ameluz^® PDT, marking an important milestone ahead of several anticipated data and regulatory events in 2026.

The databases for the treatment phase of the Company's Phase 3 clinical study evaluating Ameluz^® PDT for the treatment of actinic keratosis (AK) on the extremities, neck and trunk as well as its Phase 2 clinical study evaluating the treatment of moderate to severe acne vulgaris were successfully locked on January 5, 2026.

All data from participants that is collected throughout each study is captured in a specific database. Locking the database enables unblinding and statistical analysis of the study results in accordance with the pre-specified study endpoints. Biofrontera expects data for both studies to be available in February of this year.

Actinic keratosis and acne vulgaris are the two skin disorders most commonly diagnosed by dermatologists in the US¹, with tens of millions of patients impacted.

"Despite the prevalence of AK and acne vulgaris, a large unmet need still exists for the treatment of these common skin conditions. An in-office treatment could significantly improve the compliance rate compared to other therapies for each of these disorders. Growing concerns about antibiotic resistance, systemic safety, and treatment burden have led dermatologists to look at different approaches to prolonged oral antibiotic and isotretinoin use for the treatment of acne². Together with the large number of AKs appearing on areas of the body other than the face and scalp we believe these two indications have the potential to increase the use of Ameluz PDT substantially if approved," commented Prof. Hermann Luebbert, Biofrontera's CEO.

Pending positive outcomes of the Phase 3 AK study, the company plans to submit a supplemental New Drug Application (sNDA) to the U.S. Food and Drug Administration (FDA) in Summer of 2026 to expand the approved use of Ameluz^® PDT for AK beyond the face and scalp. Results from the Phase 2 acne vulgaris study are expected to be presented to the FDA in early Q3 2026 and are intended to provide the basis of a future Phase 3 program, with the goal of achieving approval for Ameluz^® PDT in this indication.

Together with the submission in December 2025 of the Company's sNDA for the treatment of superficial Basal Cell Carcinoma (sBCC) with Ameluz^® PDT, these milestones support Biofrontera's strategy to expand the clinical utility of its PDT platform and advance additional growth opportunities.

For further information on the two studies, please see Biofrontera's press releases³^,⁴ from September 16, 2025, and August 25, 2025. The 1-year follow-up phase of the phase III study on AK is still ongoing, but not required for FDA approval of the indication.

About Actinic Keratosis

AK is the most common pre-cancerous skin lesion caused by chronic sun exposure that may, if left untreated, develop into life-threatening skin cancer called squamous cell carcinoma. 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.⁵

About Acne Vulgaris

Acne vulgaris is the most common skin condition in the United States, affecting an estimated 50 million people each year¹. Although often associated with adolescence, it persists into adulthood, impacting approximately 40% of adults². The condition ranges from mild blackheads and whiteheads to severe inflammatory forms such as nodules and cysts, which can cause permanent scarring and have profound effects on mental health and self-esteem³. Current U.S. guidelines recommend topical therapies, oral antibiotics, and isotretinoin for moderate to severe acne⁴. However, these treatments are frequently limited by significant systemic side effects, driving demand for safer and more effective alternatives. The U.S. acne treatment market, valued at $5.7 billion in 2024 and projected to grow at a 5.3% CAGR, reflects this unmet need⁵. More than 55% of spending is currently directed to oral antibiotics and isotretinoin⁶, underscoring the reliance on systemic therapies and the opportunity for novel treatment approaches.
