Chiesi Global Rare Diseases Supports Continued Generation of Real-World and Scientific Evidence in Epidermolysis Bullosa (EB), Including New Data Presented at 2026 PeDRA Annual Conference

-- New mechanistic research and clinician-reported real-world experience adds to the evolving evidence base for birch triterpenes in EB --

-- Chiesi proudly marks EB Awareness Week (October 25–31) with continued research, awareness and support for the EB community --

BOSTON, Oct. 15, 2026 (GLOBE NEWSWIRE) -- Chiesi Global Rare Diseases, a business unit of the Chiesi Group established to deliver innovative therapies and solutions for people living with rare diseases, today announced the presentation of new scientific data and real-world experience relating to birch triterpenes topical gel at the 14^th Annual Conference of the Pediatric Dermatology Research Alliance (PeDRA), to be held October 15–17, 2026, in Alexandria, Virginia.

The presentations add to a growing body of real-world clinical evidence and scientific data, providing further insights into birch triterpenes topical gel in clinical practice and advancing scientific understanding of its mechanism of action. Birch triterpenes topical gel was approved by the European Commission in June 2022 for the treatment of partial-thickness wounds in patients 6 months and older with junctional and dystrophic epidermolysis bullosa (EB) and approved for the same indication by U.S. Food and Drug Administration (FDA) in December 2023 and by the UK Medicines and Healthcare products Regulatory Agency (MHRA) in September 2022.

Together, the PeDRA presentations will bring new and evolving insights to the pediatric dermatology community. Two of the three presentations build on real-world experience and scientific evidence presented in 2026, including an expanded analysis of mechanism-of-action data introduced at the 55^th Annual European Society for Dermatological Research (ESDR) Meeting in September, and additional real-world experience with birch triterpenes as part of combination treatment approaches first shared at the 51^st Annual Society for Pediatric Dermatology (SPD) Meeting in July. A third presentation will share new real-world observations, for the first time at PeDRA, on the use of birch triterpenes in adolescents with chronic, life-long wounds.

“For a condition such as epidermolysis bullosa, where long-term clinical experience is essential, real-world evidence can provide important insights into how wound management approaches are being used across different care settings,” said Dr. Lara Wine Lee, MD, PhD, FAAD, Pediatric Dermatologist at Medical University of South Carolina. “Sharing these observations alongside mechanistic research helps expand the evidence base and identify questions that warrant further investigation, ultimately contributing to continued learning across the EB community.”

“Every piece of evidence generated through research and clinical experience is ultimately in service of people living with epidermolysis bullosa and their families,” said Rachele Berria, MD, PhD, Senior Vice President, Medical Affairs of Chiesi Global Rare Diseases. “This year’s research is especially meaningful because it brings together laboratory insights and real clinical care. Combining what we learn about birch triterpenes with what clinicians' experience caring for patients helps guide where the science needs to go next. Heading into EB Awareness Week, we are proud to support research that brings progress to the EB community.”

For Chiesi, advancing the science is only one part of showing up for the EB community. As the global EB community comes together for EB Awareness Week (October 25-31), Chiesi continues to support initiatives that amplify the voices and everyday experiences of people living with EB. These include the LivingWithEB platform, a digital space where people with EB can connect through personal stories and disease information, and the amplification of DEBRA International's Inside Out campaign, which brings greater visibility to the often-unseen impact of EB in daily life. Together, these efforts reflect Chiesi’s commitment to listening to and working alongside the EB community to increase understanding and help advance better care for those living with this rare disease.

About Birch Triterpenes Topical Gel
Birch triterpenes topical gel (birch bark extract gel) is indicated for the treatment of partial thickness wounds associated with dystrophic and junctional epidermolysis bullosa (EB) in patients 6 months and older. The gel should be applied to the wound surface at a thickness of approximately 1 mm and covered with a sterile, non-adhesive wound dressing. Alternatively, the gel can be applied to the dressing so that the gel is in direct contact with the wound. Birch triterpenes topical gel should be applied to cleansed wounds and reapplied at each wound dressing change.¹

About Epidermolysis Bullosa
Epidermolysis bullosa (EB) is a rare genetic disorder characterized by extreme skin fragility and blistering. Severe forms lead to chronic blisters, ulcerations, scarring, joint contractures, esophageal strictures, a high risk of squamous cell carcinoma, infections and premature death.²

Epidermolysis Bullosa is a group of rare, inherited skin fragility disorders in which the skin is very weak and fragile. Even minor friction to the skin can cause painful blisters and open wounds that are slow to heal and can lead to significant scarring.² Not only does EB affect the external skin, but the lining of the mouth, throat, eyes, and the digestive system.³ There are four main types of EB and they range in how severely they affect a person. Some of the most severe forms of EB include junctional EB (JEB) and dystrophic EB (DEB). These severe EB subtypes may be accompanied by multiple complications (e.g. sepsis, failure to thrive, severe anemia, and cancer) leading to a reduced lifespan. People with EB must take extraordinary measures to protect their fragile skin, and despite their efforts, many live with chronic wounds all over their body. These wounds are extremely painful and itchy.³ Pain can be persistent and severe in EB patients.⁴ Globally, an estimated 500,000 people are living with EB.⁵
