CAMBRIDGE, Mass., May 08, 2025 (GLOBE NEWSWIRE) -- Wave Life Sciences Ltd. (Nasdaq: WVE), a clinical-stage biotechnology company focused on unlocking the broad potential of RNA medicines to transform human health, today announced financial results for the first quarter ended March 31, 2025, and provided a business update.

“We’ve continued our consistent execution across modalities as we completed dosing in the first two cohorts of our INLIGHT trial in obesity, advanced our RestorAATion-2 trial in AATD, and delivered positive data from our FORWARD-53 clinical trial in DMD. We are on track to deliver multiple clinical datasets this year that will further demonstrate our broad capabilities across modalities and our leadership in RNA medicines,” said Paul Bolno, MD, MBA, President and Chief Executive Officer at Wave Life Sciences. “Our RestorAATion-2 trial of WVE-006, a subcutaneously-dosed GalNAc-conjugated RNA editing oligonucleotide, continues to advance and we are on track to deliver data from multiple dose cohorts this year, which will inform the therapeutic potential of WVE-006 and our pipeline of wholly-owned GalNAc-RNA editing programs. In obesity, we are evaluating WVE-007, our INHBE GalNAc-siRNA in our ongoing INLIGHT clinical trial, and are on track to deliver the first clinical data in the second half of this year. This program has potential to transform the obesity treatment paradigm with healthy weight loss, preservation of muscle mass, and infrequent dosing of once or twice a year.”

Dr. Bolno continued, “In DMD, we delivered the first-ever substantial improvements in muscle health with an exon skipping therapy and showed statistically significant and clinically meaningful functional data from our FORWARD-53 trial of WVE-N531 in March. We have been engaged with the community in discussing our recent clinical results and are excited by the potential to bring a meaningful new potential treatment option to boys with DMD. In HD, our WVE-003 program has industry-leading CSF mutant lowering, and remains the only program to have successfully demonstrated allele-selective knockdown with wild-type HTT preservation in the clinic. We are actively engaged with both the HD community and prospective strategic partners, as we continue to prepare for our potentially registrational Phase 2/3 study.”

Recent Business Highlights and Expected Milestones

Obesity

• WVE-007 is a GalNAc-conjugated small interfering RNA (GalNAc-siRNA) designed to silence INHBE mRNA, an obesity target with strong evidence from human genetics. WVE-007 is Wave’s first siRNA candidate to enter clinical development and uses Wave’s best-in-class proprietary oligonucleotide chemistry.
• INLIGHT is an ongoing, first-in-human, placebo-controlled, clinical trial evaluating WVE-007 in adults living with overweight or obesity and assesses safety, tolerability, pharmacokinetics, biomarkers for target engagement, body weight and composition, and metabolic health.
• Today, Wave announced that it has completed dosing in the first and second single dose cohorts of INLIGHT.
• Next week, in oral presentations at the 32^nd European Congress on Obesity (ECO) and the American Society of Gene and Cell Therapies (ASGCT) 28^th Annual Meeting, Wave will highlight its preclinical data supporting WVE-007’s potential in multiple treatment settings with potential for dosing once or twice a year, including:
  • A single dose of Wave’s INHBE siRNA led to weight loss on par with semaglutide, but with no muscle loss.
  • When administered as an add-on to semaglutide, a single dose of Wave’s INHBE siRNA doubled the amount of weight loss.
  • Wave’s INHBE siRNA curtailed rebound weight gain when semaglutide treatment was discontinued, highlighting its potential as an off-ramp and maintenance treatment following GLP-1 treatment.
• Expected milestones: Wave expects to deliver clinical data from INLIGHT in the second half of 2025, including safety, tolerability and biomarkers reflective of healthy weight loss.

AATD (Alpha-1 antitrypsin deficiency)

• WVE-006 is a GalNAc-conjugated, subcutaneously delivered, A-to-I RNA editing oligonucleotide (AIMer) that is uniquely designed to address alpha-1 antitrypsin deficiency (AATD)-related lung disease, liver disease, or both.
• RestorAATion clinical program: Multi-dosing is complete in RestorAATion-1 (healthy volunteers) at a dose level greater than those planned for any cohort in its ongoing RestorAATion-2 study. RestorAATion-2 is a Phase 1b/2a open-label study with both single and multiple ascending dose portions, which is evaluating the safety, tolerability, pharmacodynamics and pharmacokinetics of WVE-006 in individuals with AATD who have the homozygous Pi*ZZ mutation.
• Multi-dosing is ongoing in the first cohort of RestorAATion-2, where patients are receiving 200 mg subcutaneous doses every two weeks.
• Dosing is also underway in the second single dose cohort at 400 mg.
• In October 2024, Wave delivered proof-of-mechanism data from a single, lowest dose of WVE-006 from the first two patients in the ongoing RestorAATion-2 clinical study, representing the first-ever clinical demonstration of RNA editing in humans. Circulating wild-type M-AAT protein in plasma reached a mean of 6.9 micromolar, representing more than 60% of total AAT. Mean total AAT protein increased to 10.8 micromolar, meeting the level that has been the basis for regulatory approval for AAT augmentation therapies.
• Expected milestones: Wave expects to share data from the complete 200 mg multidose and single dose cohorts of RestorAATion-2 in the third quarter of 2025, and data from the complete 400 mg single dose cohort in the fall of 2025.

Emerging wholly owned siRNA and RNA editing pipeline

• Wave is advancing new targets across multiple disease areas to expand its pipeline of wholly owned programs in both rare and common diseases. Wave’s pipeline of preclinical candidates utilize Wave’s proprietary chemistry to achieve best-in-class silencing using siRNA and RNA editing in a variety of hepatic and extrahepatic tissues, including in the CNS with multiple AIMers such as MECP2. Within RNA editing, Wave has demonstrated the ability to correct single variants to restore wild-type protein function and to increase the stability of the mRNA transcript to upregulate protein levels.
• Wave’s wholly owned RNA editing pipeline includes programs that use GalNAc conjugation and have efficient clinical paths to proof-of-concept. These include PNPLA3 mRNA correction to potentially address the nine million homozygous I148M carriers in the US and Europe at risk for a variety of liver diseases, and mRNA upregulation (LDLR) and mRNA correction (APOB), which together would address approximately one million people living with heterozygous familial hypercholesterolemia (HeFH) in the US and Europe.
• Next week, in an oral presentation at the ASGCT 28^th Annual Meeting, Wave plans to share preclinical data demonstrating proof-of-principle for the use of AIMers in lung indications, including cystic fibrosis (CF). Available therapies for CF cannot address stop codon mutations in the CFTR gene. In human bronchial epithelial cells with CFTR mutation W1282X, CFTR AIMers increased expression of CFTR mRNA 3-fold and restored up to 50% of functional wild-type CFTR protein levels.
• Expected milestones: Wave plans to share new preclinical data from hepatic and extra-hepatic RNA editing programs in 2025 and to initiate clinical development of additional RNA editing programs, including PNPLA3, LDLR, and APOB, in 2026.

DMD (Duchenne muscular dystrophy)

• WVE-N531 is an exon skipping oligonucleotide being developed as a disease modifying treatment for boys with Duchenne muscular dystrophy amenable to exon 53 skipping. WVE-N531 was designed using Wave’s best-in-class oligonucleotide chemistry modifications, including PN backbone chemistry. WVE-N531 has received Orphan Drug Designation and Rare Pediatric Disease Designation from the U.S. Food & Drug Administration.
• In March 2025, Wave announced positive 48-week data from its Phase 2, open-label FORWARD-53 clinical trial of WVE-N531, which included:
  • Statistically significant and clinically meaningful improvement of 3.8 seconds in Time-to-Rise vs. natural history with largest effect observed relative to any approved dystrophin restoration therapy at 48 weeks; additional functional benefits observed in other outcome measures including NSAA.
  • First-ever demonstration of substantial improvements in muscle health with exon skipping – statistically significant reduction in fibrosis driven by decreases in inflammation and necrosis, coupled with transition from regenerative to mature muscle; decreases in creatine kinase and circulating inflammatory biomarkers.
  • Dystrophin expression stabilized between 24 and 48 weeks and averaged 7.8%, with 88% of boys above 5% average dystrophin.
  • WVE-N531 remains safe and well-tolerated with no Serious Adverse Events.
• All participants in FORWARD-53 elected to advance to the extension portion of the clinical trial, which is currently ongoing with boys receiving monthly doses of WVE-N531. To augment monthly data and ensure a monthly regimen at a potential launch, Wave is also expanding FORWARD-53 to include additional boys who will be dosed monthly.
• Also in March 2025, Wave announced that the company met with the U.S. Food and Drug Administration (FDA) on WVE-N531 to discuss its interim 24-week data and initial plans for the confirmatory trial, where the Agency confirmed that the accelerated approval pathway using dystrophin expression as a surrogate endpoint remains open.
• Expected milestones: Wave plans to file a New Drug Application (NDA) in 2026 to support accelerated approval of WVE-N531 with monthly dosing. Wave expects to submit clinical trial applications (CTAs) for additional exon skipping programs in 2026.
  

HD (Huntington’s disease)

• WVE-003 is a first-in-class, allele-selective oligonucleotide for the treatment of Huntington’s disease (HD). In the SELECT-HD clinical trial, data demonstrated the first-ever allele-selective reduction in CSF mHTT protein and preservation of healthy, wtHTT with multiple doses of WVE-003, as well as a statistically significant correlation between mHTT reduction and slowing of caudate atrophy. By reducing mHTT at the mRNA and protein level, WVE-003 addresses underlying drivers of neurodegeneration. In addition, by sparing wtHTT protein, which is critical to the health of the central nervous system, WVE-003 is uniquely positioned to address presymptomatic HD patients, as well as symptomatic patients.
• Wave has received supportive initial feedback from FDA, who recognize the severity of HD and are receptive to and engaged with Wave regarding a potential pathway to accelerated approval. Preparation is ongoing for a potentially registrational, global Phase 2/3 study of WVE-003 in adults with SNP3 and HD using caudate atrophy as a primary endpoint.
• Expected milestones: Wave expects to submit an Investigational New Drug (IND) application for a potentially registrational Phase 2/3 study of WVE-003 in HD in the second half of 2025.
