Remission & chronicity

Spontaneous remission

No spontaneous remission; lifelong clotting factor deficiency; joint damage progressive with each bleed without treatment; with prophylaxis, normal lifespan achievable

Best-intervention remission

Emicizumab prophylaxis (HAVEN studies): 87% reduction in bleeds vs on-demand FVIII; fitusiran (antithrombin RNAi): monthly subcutaneous injection, 89% reduction in bleeds; gene therapy (valoctocogene roxaparvovec): 94% reduction in bleeds at 5 years (GENEr8-1)

Gap size

Large — gene therapy offers functional cure but access is essentially the entire gap

Primary barrier

access

Barrier detail: Gene therapy for haemophilia A (valoctocogene roxaparvovec/Roctavian, FDA approved 2023) and B (fidanacogene elaparvovec/Beqvez) represent functional cures in eligible patients but cost $2.9-3.5M; IgG immune responses limit retreatment; durability questions persist at 5 years; most patients in LMICs remain on factor concentrates

Last SoC change: 2023 — fidanacogene elaparvovec (Beqvez, gene therapy for HemB) FDA approved; 2023 valoctocogene roxaparvovec (Roctavian) FDA approved for HemA; fitusiran (antithrombin siRNA) 2023; emicizumab (Hemlibra) 2017; factor concentrates standard since 1960s

Alterations

32 total · Types A (molecular) through E (functional). Molecular rows are Open Targets gene–disease associations (evidence column = OT association score), not measured levels; phenotypes are HPO terms annotated directly to this disease (Monarch); type T rows are outcome measures used in completed ClinicalTrials.gov studies, not alterations of the disease.
