AAD 2025: Almirall presents early-stage pipeline progress and real-world evidence on demonstrating AK treatment success and patient satisfaction with Tirbanibulin

• New data analysis on Tirbanibulin shows consistent treatment response for actinic keratosis (AK): data from phase IV and real-world evidence studies show consistently high levels of response as well as patient satisfaction.
• Presentation of phase I data of the early-stage pipeline asset LAD191, a high affinity monoclonal antibody targeting IL-1RaP (interleukin-1 receptor accessory protein), which is expected to impact immune-modulated skin diseases by blocking multiple proinflammatory pathways.
• Almirall´s strong presence at the AAD conference, sharing new data on Almirall’s dermatology and pipeline portfolio demonstrate its dedication to the medical community and patients living with skin diseases.

Almirall, S.A. (ALM), a global pharmaceutical company dedicated to medical dermatology presents five scientific posters at the 2025 American Academy of Dermatology (AAD) Annual Meeting - including new data on tirbanibulin, a topical treatment for actinic keratosis (AK) and progress of its early-stage asset LAD191, a high-affinity monoclonal antibody targeting interleukin-1 receptor accessory protein (IL-1RAP). These presentations provide valuable insights into patient outcomes, safety, and real-world effectiveness of tirbanibulin for the treatment of AK and demonstrate the ongoing commitment of Almirall to finding novel solutions for skin diseases through progressing its early-stage clinical development pipeline.

"Our close collaboration with the dermatology community and patients allows us to better understand their needs and develop effective solutions. The findings presented at AAD 2025 show our focus on delivering impactful data on our established products as well as progressing our early-stage pipeline. The data on tirbanibulin for the treatment of actinic keratosis highlight the importance of a patient-centered approach to achieve treatment success. Presenting data from the phase I study of our early-stage asset LAD191 is an important step towards adding new impactful treatments to our dermatology portfolio in the future," stated Dr. Volker Koscielny, Almirall’s Chief Medical Officer.

Tirbanibulin data: The new data analysis presented at the AAD demonstrates the impact of tirbanibulin on overall AK treatment success and clearance while also assessing patient satisfaction and willingness to continue the treatment. The data show the product´s demonstrated safety and tolerability profile through a combination of clinical trial data and real-world evidence. The analysis from Phase III, phase IV, and real-world studies provide further evidence for tirbanibulin´s tolerability, safety profile and patient satisfaction.

According to Dr. Darrell Rigel, MD MS and Clinical Professor, Mount Sinai Icahn School of Medicine, "Patient satisfaction is a significant aspect of treatment outcomes. The results of these studies with tirbanibulin indicate notable improvements in patient satisfaction in real-world scenarios, which supports adherence to AK treatment protocols thus paving the way for more sustainable outcomes. By prioritizing patient experience and addressing their needs, the effectiveness of therapies can be enhanced, which can lead to an overall improvement in the quality of care."

LAD191 data: Almirall also presents progress on its early-stage pipeline showing data from the Phase I clinical study with LAD191, a high-affinity monoclonal antibody targeting interleukin-1 receptor accessory protein (IL-1RAP), which is in development for the treatment of immune-modulated skin diseases such as Hidradenitis suppurutiva. The results in healthy volunteers support the safety and tolerability and add to previous pre-clinical studies that have demonstrated LAD191’s ability to inhibit pro-inflammatory cytokines. Blocking multiple pathways through IL-1RaP inhibition is anticipated to provide greater clinical benefit in attenuating proinflammatory responses compared to single cytokine inhibition.

Addressing Unmet Needs in Medical Dermatology

Medical dermatology remains a field with significant unmet needs, as many skin conditions still have limited treatment options. Dermatological diseases not only impact physical health but also affect emotional wellbeing and quality of life of patients. As a key participant in AAD 2025, Almirall continues to foster knowledge exchange and collaboration, reinforcing its commitment to deliver transformative dermatological solutions that improve patient lives.

With over 80 years of experience in healthcare, Almirall is committed to advancing science in dermatology through continuous investment in research and development and by fostering strong partnerships with the medical and scientific communities. The company's expanding portfolio in medical dermatology, particularly its focus on advanced biologic solutions for psoriasis and atopic dermatitis, underscores its dedication to improving dermatological treatments and enhancing patient outcomes.

Almirall´s presence at the AAD 2025 is an important opportunity to connect with healthcare professionals, partners, and industry peers at AAD 2025, a leading international forum for medical dermatology expertise and collaboration.
