Rhea-AI Filing Summary

Biofrontera Inc. reported positive Phase 2b clinical results for its Ameluz® photodynamic therapy in moderate to severe acne vulgaris. In the 3-hour incubation per-protocol group, Ameluz achieved a 57.97% reduction in inflammatory lesions versus 36.51% with vehicle, and 25% of Ameluz patients met the mIGA co-primary endpoint compared with 21.4% on vehicle.

The 3-hour regimen also showed larger absolute reductions in inflammatory, non-inflammatory and total lesion counts and a safety profile consistent with prior PDT experience, with mainly mild to moderate burning and itching. Patient satisfaction was high, and the company plans to present these Phase 2b data to the FDA in Q3 2026 to discuss potential next development steps.

Insights

Phase 2b acne data are encouraging but still mid-stage and exploratory.

Biofrontera reported that Ameluz® PDT with a 3-hour incubation reduced inflammatory acne lesions by 57.97% versus 36.51% for vehicle, and improved mIGA responder rates (25% vs. 21.4%). These outcomes suggest a potential clinical signal in moderate to severe acne vulgaris.

The safety profile aligned with known photodynamic therapy effects, mainly burning sensation and pruritus, with modest pain scores on an 11-point scale. High patient satisfaction, including 85.7% willingness to choose PDT again, may be important for an in-office procedure where tolerability and cosmetic outcomes matter.

The company intends to present the Phase 2b data to the FDA in Q3 2026 to discuss next steps. Actual future impact depends on regulatory feedback, Phase 3 trial design and results, and how Ameluz® PDT might fit among existing acne treatments if ultimately approved.

Exhibit 99.1

 

Biofrontera Inc. Reports Positive Phase 2b Results Supporting Further Development of Ameluz® Photodynamic Therapy for moderate to severe Acne Vulgaris

 

● Phase 2b study demonstrated greater reductions in inflammatory acne lesions with Ameluz® PDT versus vehicle

 

● 3-hour incubation regimen identified as the most promising protocol for further clinical development

 

● Acne vulgaris represents a promising potential future indication for Ameluz®, significantly broadening the Company’s dermatology pipeline

 

WOBURN, Mass. (March 9, 2026) – Biofrontera Inc. (Nasdaq: BFRI) (“Biofrontera” or the “Company”), a biopharmaceutical company specializing in the development and commercialization of photodynamic therapy (PDT), today announced results of its Phase 2b clinical trial evaluating Ameluz® (aminolevulinic acid HCL) topical gel, 10% PDT for the treatment of moderate to severe acne vulgaris (AV).

 

The multicenter, randomized, double-blind study compared Ameluz® and vehicle gel using two incubation times (1 hour and 3 hours) prior to illumination with the BF-RhodoLED® lamp. Participants received one tube of Ameluz® or vehicle gel applied to the entire face, followed by incubation and illumination with the red light. Up to three PDT treatments were administered at one-month intervals, and patients were followed up for two months after receiving the final PDT treatment.

 

The study had co-primary endpoints, one of which looked at the relative reduction in inflammatory lesion counts. The other required an improvement of at least two grades on a 5-point modified Investigator Global Assessment (mIGA) scale and that the patient was rated “clear” or “almost clear” (score 0 or 1).

 

Clinical results

 

Greater improvements in both inflammatory lesion counts and mIGA scores were observed with Ameluz® vs. vehicle with the 3-hour incubation regimen, identifying this as the most promising protocol for further clinical investigation in acne vulgaris.

 

In the 3-hour per-protocol population, the Ameluz group achieved a 57.97% reduction in inflammatory lesions (n=20), compared with 36.51% (n=14) in the corresponding vehicle group. For the mIGA analysis, 25% of the Ameluz treated patients met this co-primary endpoint with 21.4% of the vehicle patients achieving the same outcome.

 

Reductions in absolute lesion counts further supported the efficacy of the 3-hour regimen. The values for inflammatory, non-inflammatory and total lesion reductions were 19.7, 23.1 and 42.7 with Ameluz vs. 15.4, 16.5 and 31.9 with vehicle.

 

 

 

 

Safety, Tolerability and Patient Satisfaction

 

Ameluz® PDT demonstrated a favorable safety profile consistent with previously reported photodynamic therapy experience. The most frequently reported treatment-related adverse events were burning sensation and pruritus, both of which were generally mild to moderate in severity.

 

In addition, the average pain scores during the 3-hour incubation PDT treatments were modest, with the values in the Ameluz group ranging from 3.4 to 3.8, and from 2.0 to 2.1 with vehicle on an 11-point scale.

 

Participants reported high overall satisfaction with PDT treatment. Of the patients who underwent the 3-hour Ameluz incubation, 85.7% said they would choose PDT again and 71.4% of them rated their esthetic outcome as “good” or “very good”.

 

Medical Need for Moderate to Severe Acne

 

Acne vulgaris is one of the most common dermatologic conditions in the US, affecting millions of patients and representing a large treatment market. It may lead to permanent scarring and can carry a significant psychosocial burden, including reduced self-esteem and depression.

 

Current treatment options include topical therapies requiring long-term daily treatment, and systemic antibiotic and oral isotretinoin which may have significant safety considerations. Additionally, increasing antibiotic resistance continues to drive interest in alternative treatment approaches.

 

As an in-office physician-administered procedure, photodynamic therapy may offer dermatologists an alternative treatment option with a high rate of compliance and that avoids patients having to undergo chronic systemic exposure.

 

“We are thrilled to reach this crucial milestone in our clinical program”, said Dr. Hermann Luebbert, CEO and Chairman of Biofrontera Inc. “The results of this Phase 2b study show promising reductions of inflammatory, non-inflammatory and total lesions with Ameluz® PDT after 3-hour incubation, as well as an improvement in the mIGA.

 

The successful completion of this study brings us a step closer to potentially offering an effective and well tolerated treatment option for patients with moderate to severe acne vulgaris. Expanding the potential indications for Ameluz® demonstrates our commitment to the development of PDT and would further strengthen our dermatology franchise.”

 

 

 

 

Mitchel P. Goldman, MD, FAAD, Medical Director of Cosmetic Laser Dermatology, Board Member of Platinum Dermatology Partners and the coordinating investigator of the study, expressed enthusiasm about its’ potential impact for the treatment of acne vulgaris. “Ameluz® PDT has shown encouraging potential for the treatment of moderate to severe acne vulgaris. We see many patients who suffer from this condition, still relying on treatment regimens that often come with a high burden for the patients. The possibility of expanding the use of Ameluz® to treat those patients with PDT is promising for physicians and our patients.”

 

The Company plans to present these Phase 2b data to the U.S. Food and Drug Administration (FDA) in Q3 2026 to discuss potential next steps to develop Ameluz® PDT for the treatment of acne vulgaris.
