CAMBRIDGE, Mass., June 27, 2025 (GLOBE NEWSWIRE) -- Biogen Inc. (Nasdaq: BIIB) today announced new data that reinforce the clinical impact of nusinersen across a broad spectrum of individuals affected by spinal muscular atrophy (SMA). These latest findings from Part C of the DEVOTE trial evaluating a higher dose regimen of nusinersen and the NURTURE trial which evaluated the approved 12 mg regimen (SPINRAZA®) in clinically presymptomatic SMA were presented at the SMA Research & Clinical Care Meeting hosted by Cure SMA in Anaheim, Calif. Biogen’s applications for the higher dose regimen of nusinersen are currently under review in the U.S., Europe, Japan and other global markets. The higher dose regimen of nusinersen comprises a more rapid loading regimen – two 50 mg doses 14 days apart – and a higher maintenance regimen – 28 mg every four months.

Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) today announced that its partner, Biogen, shared positive topline results from the Phase 1 study of salanersen (ION306/BIIB115), an investigational antisense oligonucleotide (ASO) being developed for the potential treatment of spinal muscular atrophy (SMA). Leveraging the same mechanism of action as SPINRAZA® (nusinersen) but designed to achieve greater potency, salanersen has the potential to achieve high efficacy and enable once-yearly dosing. Both dose levels tested, 40 mg and 80 mg, given once a year, were generally well-tolerated and led to substantial slowing of neurodegeneration, as shown by reductions in neurofilament. Exploratory clinical outcome data show clinically meaningful improvements in function and attainment of new World Health Organization (WHO) milestones over one year. These data will be presented today at the SMA Research & Clinical Care Meeting hosted by Cure SMA in Anaheim, Calif.

CAMBRIDGE, Mass., June 25, 2025 (GLOBE NEWSWIRE) -- Biogen Inc. (Nasdaq: BIIB) announced topline results from the Phase 1 study of salanersen (BIIB115/ION306), an antisense oligonucleotide (ASO) being developed for the treatment of spinal muscular atrophy (SMA). Leveraging the same mechanism of action as SPINRAZA (nusinersen) but designed to achieve greater potency, salanersen has the potential to achieve high efficacy and enable once yearly dosing. An interim analysis of the Phase 1 study in participants with SMA who were previously treated with gene therapy was conducted to inform the decision on whether to move salanersen forward into registrational studies. Both dose levels tested, 40 mg and 80 mg, given once a year, were generally well-tolerated and led to substantial slowing of neurodegeneration, as shown by reductions in neurofilament. Exploratory clinical outcome data shows clinically meaningful improvements in function and attainment of new World Health Organization (WHO) milestones over 1 year. These data will be presented today at the SMA Research & Clinical Care Meeting hosted by Cure SMA in Anaheim, Calif.

Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) today announced positive topline results from the Essence study of olezarsen in people with moderate hypertriglyceridemia (fasting triglycerides ≥150 mg/dL to <500 mg/dL) with or at risk for atherosclerotic cardiovascular disease (ASCVD). Nearly all the participants were on current standard of care lipid-lowering medicines. The trial met its primary endpoint with a statistically significant placebo-adjusted 61% and 58% reduction in triglyceride (TG) levels at 6 months with the 80 mg and 50 mg monthly doses, respectively (p <0.0001). Olezarsen also met all key secondary endpoints in the study. The vast majority of participants reached <150mg/dL, reflecting a reduction to normal TG levels. Olezarsen demonstrated a favorable safety and tolerability profile in the study. Ionis plans to submit an abstract for presentation at an upcoming scientific conference. Data from the pivotal Phase 3 CORE and CORE2 studies evaluating olezarsen for the treatment of severe hypertriglyceridemia (sHTG) are expected in Q3 2025.

Applications are based on data from the DEVOTE study, which demonstrate the potential for the investigational higher dose regimen of nusinersen to advance the treatment of SMA

CAMBRIDGE, Mass., Oct. 08, 2024 (GLOBE NEWSWIRE) -- Biogen Inc. (Nasdaq: BIIB) today announced detailed results from Part B and Part C of the Phase 2/3 DEVOTE study evaluating the safety and efficacy of an investigational higher dose regimen of nusinersen in spinal muscular atrophy (SMA), showing benefits in both individuals previously treated and treatment-naïve to nusinersen with infantile-onset or later-onset SMA. The investigational, higher dose regimen of nusinersen comprises a more rapid loading regimen, two 50 mg doses 14 days apart, and higher maintenance regimen, 28 mg, every 4 months, compared to the approved nusinersen regimen (SPINRAZA®). Data to be presented during the World Muscle Society (WMS) 2024 Congress (Oct. 8-12, 2024 in Prague) highlight the potential of this investigational higher dose regimen to help address remaining unmet need in SMA.

BOSTON, Sept. 04, 2024 (GLOBE NEWSWIRE) -- Praxis Precision Medicines, Inc. (NASDAQ: PRAX), a clinical-stage biopharmaceutical company translating genetic insights into the development of therapies for central nervous system (CNS) disorders characterized by neuronal excitation-inhibition imbalance, today announced that that it will present preclinical and clinical data from three of its epilepsy programs at the International League Against Epilepsy (ILAE) 15th European Epilepsy Congress (EEC), being held from September 7 to 11, 2024 in Rome, Italy.

CAMBRIDGE, Mass., Sept. 04, 2024 (GLOBE NEWSWIRE) -- Biogen Inc. (Nasdaq: BIIB) today announced positive, topline data from the pivotal cohort (Part B) of the Phase 2/3 DEVOTE study evaluating the safety and efficacy of a higher dose regimen of nusinersen in treatment-naïve, symptomatic infants with spinal muscular atrophy (SMA). The investigational higher dose regimen of nusinersen comprises a more rapid loading regimen, two 50 mg doses 14 days apart, and a higher maintenance regimen, 28 mg, every 4 months, compared to the approved nusinersen regimen (SPINRAZA). The study met its primary endpoint at six months, achieving a statistically significant improvement in motor function in infants who received the higher dose regimen as compared to a prespecified matched sham (untreated) control group from the ENDEAR study.

CAMBRIDGE, Mass. and CARLSBAD, Calif., May 16, 2024 (GLOBE NEWSWIRE) -- Biogen Inc. (Nasdaq: BIIB) and Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) announced the decision to terminate development of BIIB105 (ION541) an investigational antisense oligonucleotide (ASO) for amyotrophic lateral sclerosis (ALS) based on topline results from the Phase 1/2 ALSpire study. BIIB105 was designed to reduce expression of ataxin-2 (ATXN2) protein and demonstrated statistically significant cerebrospinal fluid (CSF) ATXN2 protein reductions in the study. However, over the 6-month placebo-controlled period, treatment with BIIB105 did not result in a reduction in levels of plasma neurofilament light chain (NfL), a marker of neurodegeneration and neuronal damage. Additionally, BIIB105 did not demonstrate an impact on clinical outcome measures of function, breathing, and strength.
