Ionis partner Roche announces new Phase 3 data showing sefaxersen significantly reduced proteinuria in people with IgA nephropathy (IgAN)
Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) partner Roche announced today late-breaking oral presentation data from the ongoing Phase 3 IMAgINATION study in adults with primary IgA nephropathy (IgAN) receiving optimized standard of care, demonstrating that investigational sefaxersen achieved a statistically significant and clinically meaningful 43.1% reduction in proteinuria (95% confidence interval [CI]: 32.5 - 52.0, P<0.0001), relative to placebo at 37 weeks, as measured by 24-hour urine protein-to-creatinine ratio (UPCR). Proteinuria is a key indicator of kidney damage and a reduction in UPCR is strongly associated with the preservation of long-term kidney function. Results presented at the American Society of Nephrology (ASN) Kidney Week 2026 also showed that, among patients with baseline hematuria (blood in urine), a greater proportion of patients achieved hematuria resolution at Week 37 with sefaxersen versus placebo.

Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending the indication extension for TRYNGOLZA® (olezarsen) as an adjunct to diet, in combination with other lipid-lowering therapies, for the treatment of adult patients with severe hypertriglyceridemia (sHTG, fasting triglyceride levels of ≥880 mg/dL [≥10 mmol/L]).

Ionis announces positive interim data from partner Roche’s Phase 3 IMAgINATION study in IgA nephropathy (IgAN)
Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) and partner Roche today announced positive prespecified interim results from the ongoing Phase 3 IMAgINATION study evaluating investigational sefaxersen in adults with primary IgA nephropathy (IgAN). The study met its primary endpoint with sefaxersen achieving statistically significant and clinically meaningful improvements in proteinuria reduction, compared to placebo at 37 weeks, as measured by 24-hour urine protein-to-creatinine ratio (UPCR).
