(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 second quarter ended June 30, 2025, and provided a business update. “We have rapidly advanced our RestorAATion-2 study following positive proof-of mechanism data last year where we observed mean total AAT protein that met the level that has been the basis for regulatory approval for AAT augmentation therapies following a single, lowest planned dose of WVE-006, our GalNAc-RNA editing candidate for AATD,” said Paul Bolno, MD, MBA, President and Chief Executive Officer at Wave Life Sciences. “We remain on track to share two comprehensive data sets from our RestorAATion-2 trial this year, beginning with multidose data in the third quarter, which will inform the therapeutic potential of WVE-006, and our pipeline of wholly-owned GalNAc-RNA editing programs.” Dr. Bolno continued, “We are also advancing our INLIGHT trial of WVE-007, our INHBE GalNAc-siRNA that uses our propriety chemistry and best-in-class design, in individuals living with overweight and obesity. Since our last update, we have expanded Cohort 2 based on the favorable safety and tolerability data and robust target engagement we observed in Cohort 1, our lowest single dose cohort, and dosed 24 additional patients in Cohort 2. This achievement confirms the successful clinical translation of our siRNA platform and preclinical modeling. It also strengthens our conviction in upcoming data from Cohort 2, which tests a dose that is projected to be therapeutically active based on preclinical weight loss data. Additionally, WVE-N531, for DMD, and WVE-003, for HD, remain on track, both of which have demonstrated potential best-in-class therapeutic profiles. Our consistent execution in the clinic has positioned us to deliver multiple robust data sets in the second half of 2025 that carry the potential to further extend our leadership in RNA medicines.” Recent Business Highlights and Expected Milestones 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: RestorAATion-1 (healthy volunteers) completed in 2024 and RestorAATion-2 (Phase 1b/2a open-label study with both single and multiple ascending dose portions) is ongoing and evaluating the safety, tolerability, pharmacodynamics and pharmacokinetics of WVE-006 in individuals with AATD who have the homozygous Pi*ZZ mutation. Positive proof-of-mechanism data was announced in October 2024 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. In addition, increases in AAT from baseline were observed as early as Day 3 and as late as Day 57.Multi-dosing is complete in the first cohort of RestorAATion-2, where patients received 200 mg subcutaneous doses every two weeks and single dosing is complete in the second single dose cohort at 400 mg. Expected milestones: Wave expects to share data from the complete 200 mg single and multidose 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. 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. Published preclinical data on Wave’s siRNA designs demonstrate unprecedented Ago2 loading following a single dose of Wave’s siRNA, leading to improved potency and durability in vivo versus comparator siRNA formats.INLIGHT is an ongoing, first-in-human clinical trial (3:1 active: placebo) 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. In the second quarter of 2025, Cohort 2 of INLIGHT, which is evaluating single 240 mg doses of WVE-007, was expanded from eight to 32 individuals. This expansion was triggered by favorable safety and tolerability, as well as robust Activin E reduction observed in Cohort 1 (75 mg; n=8), the lowest single dose cohort. The 240 mg dose level is predicted to be therapeutically active based on Wave’s preclinical diet-induced obesity (DIO) mice data, where a single dose of INHBE GalNAc-siRNA led to potent and durable reductions of both INHBE mRNA and Activin E protein and drove weight loss.Today, Wave announced dosing is complete for these additional participants in the expanded Cohort 2 and data from both Cohort 1 and Cohort 2 are expected in the fourth quarter of 2025.Dosing is also underway in Cohort 3 (400 mg) with data anticipated in the first quarter of 2026. In June 2025, at the American Diabetes Association’s 85th Annual Scientific Sessions, Wave presented its preclinical DIO data that support WVE-007’s potential to reduce fat, preserve muscle and induce healthy weight loss with dosing once or twice a year. Key highlights include: A single dose of INHBE GalNAc-siRNA led to potent and durable reductions of both INHBE mRNA and Activin E protein, which drove weight loss on par with semaglutide with preserved muscle mass.A single dose of INHBE GalNAc-siRNA led to shrinkage of adipocytes and lower inflammatory state of visceral adipose tissues in DIO mice, with strong suppression of pro-inflammatory M1 macrophages in visceral fat of DIO mice, highlighting potential mechanistic insights into the risk reduction for type 2 diabetes and coronary artery disease suggested by human genetics. Expected milestones: Wave expects to deliver data from the expanded Cohort 2 (240 mg) as well as data from Cohort 1 (75mg) of INLIGHT in the fourth quarter of 2025, including safety, tolerability and measurements reflective of healthy weight loss. Data from Cohort 3 (400 mg) of INLIGHT are anticipated in the first quarter of 2026. 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 utilizes Wave’s proprietary chemistry to achieve best-in-class siRNA silencing and RNA editing in a variety of hepatic and extrahepatic tissues. 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 plans to host a Research Day in the fall of 2025, where the company expects to share updates from its clinical and preclinical pipeline of RNA medicines. 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 a positive Phase 2, open label clinical trial, boys receiving WVE-N531 for 48 weeks had a statistically significant and clinically meaningful improvement in Time-to-Rise vs. natural history, the first-ever demonstration of substantial improvements in muscle health with exon skipping. Additionally, WVE-N531 was safe and well-tolerated with no Serious Adverse Events.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 individuals living with HD who are presymptomatic as well as those who are symptomatic.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. Financial Highlights Cash and cash equivalents were $208.5 million as of June 30, 2025, compared to $302.1 million as of December 31, 2024. Wave expects that its current cash and cash equivalents will be sufficient to fund operations into 2027. Potential future milestones and other payments to Wave under its GSK collaboration are not included in its cash runway.Revenue recognized was $8.7 million for the second quarter of 2025 as compared to $19.7 million in the prior year quarter.Research and development expenses were $43.5 million in the second quarter of 2025 as compared to $40.4 million in the same period in 2024.General and administrative expenses were $18.0 million in the second quarter 2025 as compared to $14.3 million in the same period in 2024.Net loss was $50.5 million for the second quarter of 2025 as compared to $32.9 million in the prior year quarter.
