Soliris (eculizumab) approval (2007)
The FDA approved Soliris, the first complement inhibitor, for paroxysmal nocturnal hemoglobinuria, a rare blood disease previously managed with transfusions and supportive care.
Soliris became the standard of care for the disease and proved targeted therapies could command premium pricing in rare diseases.
It set a commercial template for ultra-rare disease drugs with small patient populations and high per-patient costs.
Like Soliris, Lisraya is a first-targeted-therapy for a rare disease with a small US population, testing how far mechanism-based drugs can reshape rare disease care.
