American Marconi Wireless News - Relief Therapeutics Receives FDA Rare Pediatric Disease Designation for RLF-TD011

RLF-TD011 is a differentiated, hypotonic acid-oxidizing solution formulated with hypochlorous acid, designed to deliver potent antimicrobial and anti-inflammatory activity while creating a wound microenvironment conducive to healing. The Company previously reported promising clinical findings supporting RLF-TD011's potential to meaningfully advance EB wound care by modulating the wound microbiome and reducing pathogenic colonization without disrupting beneficial bacteria.

"The FDA's decision to grant Rare Pediatric Disease designation to RLF-TD011 underscores both the critical need for new options for patients living with EB and the potential of our investigational therapy," said Giorgio Reiner, chief scientific officer of Relief. "We look forward to continued engagement with the FDA and to sharing the next steps in our development plan following our upcoming pre-IND meeting."

The FDA grants RPD designation to product candidates targeting serious or life-threatening diseases that primarily affect individuals aged 18 years or younger and impact fewer than 200,000 people in the U.S. Companies that receive marketing approval for an RPD-designated indication may be eligible-subject to certain conditions, including congressional reauthorization of the program for designations granted after December 20, 2024-to receive a Priority Review Voucher (PRV), which grants expedited FDA review for a future marketing application. These vouchers are transferable; in May 2025, a PRV awarded following the approval of a treatment for a rare form of EB was sold for $155 million.

ABOUT EPIDERMOLYSIS BULLOSA
Epidermolysis bullosa (EB) is a group of rare, inherited connective tissue disorders characterized by extreme skin fragility, leading to blistering and wounds from minor friction or injury. In severe cases, blisters can develop into chronic wounds or form in internal organs such as the mouth or esophagus, leading to painful wounds, recurrent infections, and a deeply impacted quality of life. EB is classified into several major inherited subtypes, each defined by the depth of blister formation within the skin's layers: epidermolysis bullosa simplex (EBS), dystrophic epidermolysis bullosa (DEB), junctional epidermolysis bullosa (JEB) and Kindler syndrome (KS). Treatment is intensive and includes wound care, infection prevention, and pain management. Approximately 500,000 individuals worldwide are affected by EB.

ABOUT RLF-TD011
RLF-TD011 is a highly pure, stabilized hypochlorous acid solution developed using Relief's proprietary TEHCLO™ technology. With strong antimicrobial properties, RLF-TD011 is a sprayable, self-administered solution for targeted wound application while avoiding skin contact and cross-contamination. Relief's acid-oxidizing solution has previously demonstrated efficacy in accelerating wound closure and reducing infections in certain clinical trials on non-EB wounds. In an investigator-initiated trial (NCT05533866), RLF-TD011 has also shown promising results in infection control and wound healing in EB patients with the most severe forms of the disease. RLF-TD011 aims to address unmet needs in EB care by efficiently controlling infection and inflammation while reducing antibiotic use and easing the intensive, time-consuming wound care routine required by current treatments. The U.S. Food and Drug Administration has granted RLF-TD011 both Orphan Drug and Rare Pediatric Disease designations for EB, and Relief plans to seek Qualified Infectious Disease Product (QIDP) designation for extended market exclusivity.
