What the current evidence supports

Human editorial judgment · 2026-09-22

Track; not yet

Why
Mechanistically validated and FDA-approved (standard full approval, per FDA.gov) with statistically significant trial results, but the addressable population (~300 US patients) and $1.14M/year price point make this a narrow, single-asset event rather than an emerging wave worth immediate deeper engagement.
Next
Monitor post-launch real-world outcomes, payer coverage decisions, the EU/Japan filings (via Recordati, expected 2027), and whether Ionis' GFAP-lowering ASO mechanism generalizes to other astrocyte-driven neurodegenerative targets before treating this as a broader platform signal.
