Latest Developments in Global Ultra-Orphan Disease Therapeutics Market

• In May 2023, the therapy Elfabrio (pegunigalsidase alfa) was approved by the U.S. Food and Drug Administration (FDA) for the treatment of adults with Fabry disease — a rare, inherited lysosomal disorder. This enzyme-replacement therapy (ERT) delivers functional α-Gal A enzyme into the bloodstream to compensate for the deficiency causing Fabry disease
• In October 2024, results from the Phase 3 “BRIGHT” study of Elfabrio were published by Chiesi Global Rare Diseases, documenting safety and efficacy of a modified dosing regimen (2 mg/kg every four weeks) over 52 weeks in adult Fabry patients previously treated with older enzyme therapies Although this alternate regimen is investigational (not yet approved globally), the study demonstrated the potential for more convenient dosing schedules, which could improve patient adherence and quality of life
• In March 2025, gene-therapy candidate EXG110 — developed for Fabry disease — was granted orphan-drug designation by the FDA. This recognition underlines growing industry commitment to next-generation, one-time gene therapies that could potentially correct the underlying genetic defect — rather than merely alleviating symptoms — offering long-term benefits for ultra-rare disease patients.
