Ionis Pharmaceuticals, Inc. - IONS STOCK NEWS

Ionis Pharmaceuticals has announced that its partner Biogen received FDA approval for QALSODY (tofersen) as the first treatment targeting a genetic cause of amyotrophic lateral sclerosis (ALS)SOD1 gene mutation. This accelerated approval is based on a significant reduction of the neurofilament light chain, a biomarker linked to neuronal damage in ALS patients treated with QALSODY. The drug is administered via injection and aims to address the severe impact of SOD1 mutations, with ongoing trials to confirm clinical benefits. Notably, QALSODY joins another Ionis-developed drug, SPINRAZA, in tackling rare neurodegenerative diseases. However, approval is contingent on further demonstration of clinical efficacy from ongoing studies.

Ionis Pharmaceuticals announced successful results from its Phase 3 NEURO-TTRansform study for eplontersen, aimed at treating hereditary transthyretin-mediated amyloid polyneuropathy (ATTRv-PN). The study met all co-primary and secondary endpoints, with a significant reduction of 82% in serum TTR concentration among treated patients compared to an 11% reduction in the placebo group (p<0.0001). Eplontersen also halted disease progression and improved quality of life, as measured by neuropathy impairment and quality of life scores. The findings, presented at AAN 2023, highlight eplontersen's potential as a new treatment option for patients with this fatal disease. The FDA has accepted a New Drug Application for eplontersen, with a PDUFA date set for December 22, 2023, while the company plans further regulatory submissions in Europe and beyond.

Ionis Pharmaceuticals announced new Phase 1b clinical data for IONIS-MAPT_Rx (BIIB080), revealing a dose-dependent reduction of tau protein in cerebrospinal fluid (CSF) in early-stage Alzheimer's patients. The study, presented at AD/PD 2023, showed a significant decrease in tau pathology measured by positron emission tomography (PET) at week 25 through week 100. In all dose groups, there was a 60% reduction in baseline CSF tau levels by study's end. The primary focus was on safety, with mild to moderate adverse events reported. The ongoing Phase 2 CELIA study for IONIS-MAPT_Rx is currently recruiting participants in the U.S.

Ionis Pharmaceuticals reported positive topline results from the 66-week analysis of the Phase 3 NEURO-TTRansform study for eplontersen in patients with hereditary transthyretin-mediated amyloid polyneuropathy (ATTRv-PN). The study met co-primary endpoints, showing significant reductions in TTR levels and improved neuropathy symptoms and quality of life. Results will be shared at the AAN Annual Meeting in April, with U.S. FDA accepting a New Drug Application for eplontersen, targeting a decision by December 22, 2023. The data indicates eplontersen may fulfill a critical need for new treatments for this severe condition.
