Ionis Reports Positive Phase III Endpoints in ALS and Kidney Disease
Question
Ionis Reports Positive Phase III Endpoints in ALS and Kidney Disease
Direct answer
Ionis Pharmaceuticals announced positive data across two partnered Phase III clinical programs. In the FUSION study, antisense candidate ulefnersen achieved its primary endpoint for patients with FUS-associated amyotrophic lateral sclerosis (FUS-ALS), prompting development partner Otsuka to initiate regulatory discussions. Concurrently, the IMAgINATION Phase III trial evaluating sefaxersen in patients with IgA nephropathy (IgAN) demonstrated statistically significant reductions in proteinuria. Both trial readouts validate Ionis' RNA targeting platform in rare neurodegenerative and renal indications. — bullish pressure on IONS.
