HAE Market Pivots to RNA and Gene Therapies as Patient 'Stickiness' Slows Uptake
SHERIDAN, WYOMING - December 2, 2025 - A wave of first-in-class hereditary angioedema (HAE) therapies is reshaping the U.S. Biotech & Research landscape, but questions remain over how quickly clinicians and patients will adopt these options in an already well-served rare disease market.
New approvals expand hereditary angioedema treatment choices
The HAE pipeline has accelerated dramatically, moving from basic C1 esterase inhibitors to sophisticated RNA-targeting and gene-editing approaches. The disease's life-threatening swelling attacks, including airway involvement, have long justified investment in both acute and prophylactic care, with the first FDA-approved preventive and on-demand therapies arriving in 2008 and 2009.
