4FDA approves leucovorin calcium as first treatment for CFD-FOLR1
The FDA has approved expanded use of Wellcovorin (leucovorin calcium) tablets for cerebral folate deficiency caused by confirmed FOLR1 gene variants, marking the first approved treatment for this rare neurological condition in adults and children.
FDA approves tividenofusp alfa for neurologic Hunter syndrome
The FDA approved Avlayah (tividenofusp alfa-eknm) to treat the neurologic manifestations of MPS II (Hunter syndrome), marking the first therapy specifically indicated for the CNS dimension of this rare lysosomal storage disorder.
FDA approves first gene therapy for severe LAD-I
The FDA approved Kresladi (marnetegragene autotemcel), the first gene therapy indicated for severe Leukocyte Adhesion Deficiency Type I, marking the first approved treatment specifically targeting the genetic root cause of this rare, life-threatening immune disorder.
Newborn screening expansion is uneven across US states
RUSP additions tell only half the story - state-level implementation timelines stretch the diagnostic-to-treatment gap, and the variation has consequences for treatment-eligibility windows in time-sensitive rare disease.

Eculizumab, ravulizumab, satralizumab, inebilizumab, and emerging mechanism programs define a competitive NMOSD prescribing landscape.
Spinal muscular atrophy long-term outcome data reshapes treatment expectations
Multi-year outcome data across nusinersen, onasemnogene abeparvovec, and risdiplam plus emerging combination strategies are clarifying long-term SMA treatment expectations.
Hemophilia gene therapy real-world data starts to clarify durability
Approved factor VIII and factor IX gene therapy products are accumulating real-world durability data that defines the addressable-population reality.
Hereditary angioedema oral options reach maturity
Oral plasma kallikrein inhibitors and emerging factor XIIa inhibitor programs are restructuring HAE prophylaxis and on-demand therapy.
Cell therapy moves into non-malignant rare disease
Cell-therapy approaches are beginning to land in non-malignant rare-disease indications including severe lupus, scleroderma, and inherited metabolic conditions.
ASO platform diversification beyond DMD is reshaping rare-disease commercial planning
The antisense oligonucleotide (ASO) platform has moved beyond the DMD foundation into multiple rare-disease indications including SMA, AdLD, Stargardt disease and adjacent conditions. The platform-level commercial logic is reshaping rare-disease portfolio strategy at multiple sponsors.
Newborn screening expands the rare-disease frontier
The expanding newborn-screening panel is changing when and how rare diseases are identified - and what therapy that opens up.
Rare-disease gene therapy after the first wave
After the first wave of approvals, the durability and access questions around rare-disease gene therapy are coming into focus.
Sickle cell gene therapy: science vs access
Approved gene therapies for sickle cell disease have created a new test of how access works for one-time, high-cost therapy.
Decentralised trials and the rare-disease infrastructure
Software-as-a-medical-device, in-vitro diagnostics, and decentralised trial infrastructure are reshaping how rare-disease therapy gets developed and delivered.

2Sickle cell disease curative therapy uptake exposes the conditioning-regimen access gap
Approved curative therapies for sickle cell disease (lentiviral gene therapy and CRISPR-edited autologous stem-cell therapy) are facing real-world uptake constrained by the conditioning regimen requirements and the specialist-centre infrastructure for autologous cell therapy.
Friedreich's ataxia real-world treatment uptake reveals the access-versus-efficacy gap
Real-world uptake of the first approved disease-modifying therapy for Friedreich's ataxia has been slower and more uneven than the pivotal trial population would have predicted. The drivers are infrastructure, payer behaviour, and patient-specialist matching, not the underlying clinical evidence.
