Ionis partner Biogen announces topline results from Phase 2 CELIA study of diranersen (BIIB080): first study to show reduction in tau pathology and cognitive benefit in patients with early Alzheimer’s diseaseMay 14, 2026 7:05 AM
Business Wire - Based on the strength of the biomarker and efficacy data, Biogen plans to advance diranersen to registrational development; CELIA did not meet its primary endpoint assessing dose response - - Robust reductions in tau pathology were observed across all studied doses, with results generally consistent with those observed in the Phase 1b study - - Pre-specified analyses of cognitive endpoints demonstrated slowing of clinical decline across all studied doses, particularly at the lowest dose - - The safety and tolerability profile of diranersen was generally consistent with the Phase 1b study - - Data will be presented at the Alzheimer’s Association International Conference (AAIC) 2026 and other upcoming scientific congresses - Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) today announced that its partner, Biogen, shared compelling topline results from the Phase 2 CELIA study evaluating diranersen (IONIS-MAPTRx/BIIB080), an investigational antisense oligonucleotide (ASO) therapy targeting tau, in individuals with early Alzheimer’s disease (AD). The CELIA results provide the first evidence from a randomized Phase 2 study of a tau-directed therapy demonstrating both robust biomarker impact and cognitive benefit in early AD. “We are highly encouraged by the topline results from CELIA, which underscore the potential of targeting tau to meaningfully impact patient outcomes in early Alzheimer’s disease,” Holly Kordasiewicz, Ph.D., executive vice president, chief development officer, Ionis. “These findings represent an important advancement for the field and underscore the impact of Ionis’ growing neurology portfolio, which now includes 13 medicines in clinical development including six that are wholly owned. We’re proud to have discovered diranersen and are deeply grateful to everyone who made this research possible.” Pre-specified analyses of cognitive endpoints demonstrated slowing of clinical decline across all studied doses, particularly in participants receiving the lowest dose of diranersen, 60 mg administered every 24 weeks. Diranersen also demonstrated robust reductions in both cerebrospinal fluid (CSF) tau and tau pathology, as measured by positron emission tomography (PET), across all studied doses, with reductions maintained throughout the dosing period. CELIA did not meet its primary endpoint assessing dose response for change from baseline on the Clinical Dementia Rating–Sum of Boxes (CDR-SB) at Week 76. “In CELIA, we believe we have seen an unprecedented and compelling confluence of efficacy and biomarkers results from a tau-directed agent in a randomized early Alzheimer’s disease study,” said Priya Singhal, M.D., M.P.H., Executive Vice President and Head of Development at Biogen. “We are excited by these Phase 2 data, which give us the confidence to advance diranersen to registrational development. We look forward to engaging with regulators and the broader Alzheimer’s disease community on next steps. I would like to thank the patients, families, investigators, and study teams who participated in this pioneering study.” The safety and tolerability profile of diranersen across all studied doses was generally consistent with the Phase 1b study and the known profile of diranersen to date. The incidence of adverse events (AEs) was comparable across dose groups, with a higher incidence of serious adverse events (SAEs) observed at the highest dose studied. CELIA is a pioneering study evaluating diranersen, a first-in-class investigational ASO designed to reduce the production of tau protein at its source in early AD. While tau plays an important role in the normal function of brain cells, in AD, abnormal tau can accumulate and form intracellular tangles that contribute to neurodegeneration and cognitive decline. Unlike many investigational approaches that have focused on targeting extracellular tau, diranersen is designed to reduce both extracellular and intracellular tau. About diranersen (IONIS-MAPTRx/BIIB080) Diranersen (IONIS-MAPTRx/BIIB080) is an investigational antisense oligonucleotide (ASO) therapy designed to target microtubule-associated protein tau (MAPT) mRNA to reduce the production of tau protein. Abnormal accumulation of tau in the brain is a hallmark of Alzheimer’s disease (AD) associated with neurodegeneration and cognitive decline. Diranersen is being investigated as a potential treatment for early AD. In 2025, the U.S. Food and Drug Administration (FDA) granted Fast Track designation to diranersen for the treatment of AD. In December 2019, Biogen exercised a license option with Ionis Pharmaceuticals and obtained a worldwide, exclusive, royalty-bearing license to develop and commercialize diranersen. Diranersen was discovered by Ionis. About the CELIA Study CELIA is a global Phase 2 randomized, double-blind, placebo-controlled, dose-ranging study evaluating the efficacy, safety and tolerability of diranersen in individuals with early Alzheimer’s disease (AD). The study enrolled 416 participants with mild cognitive impairment due to AD or mild AD dementia. All participants enrolled in CELIA had not previously received anti-amyloid therapy. The study evaluated three doses of diranersen administered intrathecally over a 76-week placebo-controlled treatment period: 60 mg every 24 weeks, 115 mg every 24 weeks and 115 mg every 12 weeks. The primary endpoint of CELIA was assessment of dose response for change from baseline on the Clinical Dementia Rating–Sum of Boxes (CDR-SB) at Week 76. Secondary and exploratory endpoints included additional clinical, biomarker and imaging measures, including cerebrospinal fluid tau biomarkers and tau positron emission tomography (PET). Additional information on the CELIA study design is available in the ClinicalTrials.gov listing for the CELIA study. An ongoing long-term extension (LTE) study is continuing to evaluate the long-term safety, tolerability and durability of diranersen in early AD.

Ionis partner GSK announces bepirovirsen accepted for Priority Review and granted Breakthrough Therapy Designation by U.S. FDA as a potential first-in-class medicine for chronic hepatitis BApril 28, 2026 2:06 AM
Business Wire
– Regulatory submission supported by Phase 3 B-Well trials demonstrating statistically significant and clinically meaningful functional cure rates in chronic hepatitis B -
– Breakthrough Therapy designation added to Fast Track Designation, recognizing potential for substantial improvement over existing treatments –
– Chronic hepatitis B is a leading cause of liver cancer globally –
– PDUFA Date of October 26, 2026 –
Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) partner GSK today announced the U.S. Food and Drug Administration (FDA) has accepted for Priority Review the New Drug Application (NDA) for bepirovirsen, an investigational antisense oligonucleotide (ASO) for the treatment of adults with chronic hepatitis B (CHB). The FDA has granted bepirovirsen Breakthrough Therapy designation and set a Prescription Drug User Fee Act (PDUFA) target action date of October 26, 2026.
“Over one million people in the U.S. are living with chronic hepatitis B and as of today, require lifelong antiviral therapy to suppress the virus,” said Brett P. Monia, Ph.D., chief executive officer, Ionis. “As the first medicine to deliver clinically meaningful functional cure rates, bepirovirsen is uniquely positioned to effectively treat CHB based on its potential to reduce the replication of hepatitis B virus, suppress hepatitis B surface antigen and stimulate the immune system. This milestone reflects the broad impact of Ionis’ science, and we look forward to the potential for bepirovirsen to help millions of people living with this devastating condition around the world.”
Breakthrough Therapy designation is intended to expedite the review of medicines that treat a serious or life-threatening condition and have shown preliminary clinical evidence indicating the potential for substantial improvement over available therapies. The designation enables greater FDA guidance on a medicine’s development program. Priority Review designation is granted to marketing applications for medicines that, if approved, would provide a significant improvement in the safety or effectiveness of the treatment, prevention or diagnosis of a serious condition, with the expectation of the FDA taking action within six months, compared to 10 months under standard review. Bepirovirsen also received Fast Track designation from the U.S. FDA in February 2024.
CHB is a major public health challenge, affecting over 250 million people worldwide and 1.7 million in the U.S. The current standard of care, typically nucleos(t)ide analogues, often requires lifelong therapy and the functional cure rates remain low, typically only 1%. Functional cure occurs when hepatitis B virus DNA and viral protein, hepatitis B surface antigen (HBsAg), are undetectable in the blood for at least 24 weeks after stopping all treatment, indicating that the disease can be controlled by the immune system without medication. Achieving functional cure is associated with significant reduction in the risk of long-term liver complications, including liver cancer.
The regulatory submission and Breakthrough Therapy designation were supported by positive results from the Phase 3 B-Well 1 and B-Well 2 trials, where bepirovirsen demonstrated statistically significant and clinically meaningful functional cure rates. Functional cure rates were significantly higher with bepirovirsen plus standard of care compared to standard of care alone across all ranked endpoints, including in patients with lower baseline HBsAg levels, where an even greater effect was observed. Bepirovirsen demonstrated an acceptable safety and tolerability profile consistent with previous studies. The data will be presented at the European Association for the Study of the Liver (EASL) 2026 Congress in May and submitted for simultaneous publication in scientific peer-reviewed journal in 2026.
GSK licensed bepirovirsen from Ionis in 2019 under a collaborative development and licensing agreement. Under the terms of the agreement, Ionis has received an upfront payment, license fee and development and regulatory milestone payments and is eligible to receive additional regulatory and sales milestone payments as well as tiered royalties of 10-12% on net sales of bepirovirsen.
Bepirovirsen is currently under regulatory review with the European Medicines Agency (EMA), the China National Medical Products Administration (NMPA) and Japan’s Ministry of Health, Labour and Welfare (MHLW). Bepirovirsen was also awarded Breakthrough Therapy Designation in China and SENKU Designation in Japan.
About B-Well 1 and B-Well 2
B-Well 1 (NCT05630807) and B-Well 2 (NCT05630820) trials are global multi-center, randomized, double-blind, placebo-controlled trials conducted in 29 countries. They assessed the efficacy, safety, pharmacokinetic profile, and the durability of functional cure in nucleos(t)ide analogue (NA)-treated participants with chronic hepatitis B and baseline surface antigen (HBsAg) ≤3000 IU/ml. The primary endpoint assessed the proportion of participants achieving functional cure in patients with baseline HBsAg ≤3000 IU/ml. A key secondary endpoint evaluated functional cure in participants with baseline HBsAg ≤1000 IU/ml. Functional cure is defined as HBsAg being undetectable in the blood for at least 24 weeks after stopping all treatment, indicating that the disease is controlled by the immune system without medication.
About Chronic Hepatitis B (CHB)
Hepatitis B is a viral infection that can cause both acute and chronic liver disease. Chronic hepatitis B occurs when the immune system is unable to clear the virus, resulting in long-lasting infection that affects more than 250 million people worldwide. The disease causes approximately 1.1 million deaths each year globally. Many patients often require lifelong antiviral therapy for viral suppression; making functional cure a critical goal in disease management.
About Bepirovirsen
Bepirovirsen is an investigational antisense oligonucleotide (ASO) designed to recognize and inhibit the production of the genetic components (i.e. RNA) of the hepatitis B virus that can lead to chronic disease, potentially allowing a person’s immune system to regain control. Bepirovirsen reduces the production of RNA and viral proteins associated with HBV, suppresses the level of hepatitis B surface antigen (HBsAg) in the blood, and stimulates the immune system to increase the chances of a durable and sustained response.

Exicure to Present Data at the Cure Spinal Muscular Atrophy Annual Conference in Dallas
Exicure’s three-dimensional spherical nucleic acid containing the nusinersen sequence prolongs survival and reduces toxicity compared to nusinersen in a spinal muscular atrophy mouse model
SKOKIE, Ill. – June 14, 2018 – Exicure, Inc. (OTCQB:XCUR), the pioneer in gene regulatory and immunotherapeutic drugs utilizing three-dimensional, spherical nucleic acid (SNA™) constructs, announced today that Exicure and its collaborators at The Ohio State University Wexner Medical Center will show preclinical data demonstrating the performance of Exicure’s SNA compound designed for use in spinal muscular atrophy (SMA). These data will be presented at the Cure SMA Annual Conference in Dallas, Texas on June 14, 2018.
“Exicure’s spherical nucleic acid version of nusinersen demonstrates increased survival and decreased toxicity in the translationally-relevant SMA mouse model,” said David Giljohann, PhD, CEO of Exicure. “We believe these results are important for developing improved treatments for patients with SMA. These data also suggest that Exicure’s technology platform could potentially create more potent therapies for other disorders of the central nervous system, including Huntington’s disease, Alzheimer’s disease, and Parkinson’s disease.”
At the meeting, Arthur Burghes, PhD, from Ohio State’s Wexner Medical Center, and Exicure will present data from preclinical studies in a SMA mouse model. The poster is titled “Nusinersen in spherical nucleic acid (SNA) format improves efficacy both in vitro in SMA patient fibroblasts and in ?7 SMA mice and reduces toxicity in mice.” The presentation will highlight that Exicure’s proprietary technology:
Prolonged survival by four-fold (maximal survival of 115 days compared to 28 days for nusinersen-treated mice);
Doubled the levels of healthy full-length SMN2 mRNA and protein in SMA patient fibroblasts when compared to nusinersen;
Doubled the quantity of healthy full-length SMN mRNA levels in spinal cord tissue compared to untreated mice;
Mitigated toxicity of nusinersen at the highest dose tested in mice.
In August 2017, Exicure and The Ohio State University established a collaboration to further validate and characterize the pharmacology of Exicure’s nusinersen-SNA compound in mouse models. This collaboration’s ongoing in vivo research is conducted by Dr. Burghes, an internationally known researcher, leading basic and clinical research on SMA and other genetic neuromuscular disorders.
About Exicure, Inc.
Exicure, Inc. is a clinical stage biotechnology company developing a new class of immunomodulatory and gene regulating drugs against validated targets. Exicure's proprietary 3-dimensional, spherical nucleic acid (SNA™) architecture unlocks the potential of therapeutic oligonucleotides in a wide range of cells and tissues.

About Spinal Muscular Atrophy (SMA)
SMA is the most common genetic cause of death for infants. SMA results from the loss of the SMN1 gene and an inability of SMN2 to produce sufficient full-length protein to make up for the loss of SMN1. The SMN1 gene, in a healthy person, produces a full-length protein that is essential to the function of the nerves that control muscles. Without sufficient SMN protein, the nerve cells cannot properly function and eventually die. This leads to debilitating and even fatal muscle weakness.
About Nusinersen
Nusinersen, marketed as Spinraza® by Biogen, is a modified antisense oligonucleotide. In December of 2016, nusinersen was approved by the US FDA for the treatment of SMA in pediatric and adult patients.
