Correcting and Replacing Wave Life Sciences Announced Positive Target Engagement Data from INLIGHT Clinical Trial of WVE-007 for Obesity During Annual Research Day
This press release corrects and replaces the company’s press release issued today, 10/29, at 4:15 p.m. ET in order to correct a typographical error in the first sub-bullet under “WVE-007 (GalNAc-siRNA)” – “Next steps.”
Dose-dependent mean reductions of Activin E of up to 85% one month post single dose of WVE-007 in INLIGHT clinical trial, exceeding levels that led to weight loss in preclinical models; WVE-007 is generally safe and well tolerated to date
Activin E reduction in lowest dose cohort of INLIGHT was sustained through 6 months, supporting once or twice a year dosing
Multiple clinical data updates from INLIGHT, including body composition and body weight, are anticipated starting in 4Q 2025
Additional updates included announcement of WVE-008, PNPLA3 RNA editing candidate for liver disease, with CTA submission anticipated in 2026
Preclinical data supports Wave’s emerging pipeline of hepatic and extra-hepatic RNA editing and siRNA programs; emerging modality adds capability to simultaneously edit and silence two unique targets with a single oligonucleotide construct
CAMBRIDGE, Mass., October 29, 2025 – 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 Activin E target engagement data from its INLIGHT clinical trial of WVE-007, a GalNAc-siRNA, for the treatment of obesity during the company’s annual analyst and investor Research Day.
“We are incredibly excited to be observing potent, durable, and dose-dependent Activin E reductions with just single doses of WVE-007 in the first three cohorts of our INLIGHT clinical trial for obesity. This indicates our preclinical data are translating and affirms we have a potential best-in-class RNAi modality enabled by our proprietary chemistry, including PN,” said Paul Bolno, MD, MBA, President and Chief Executive Officer of Wave Life Sciences. “We also continue to lead the field in RNA editing. With the successful clinical translation of WVE-006 for AATD, we are further expanding our editing pipeline and have now selected WVE-008 as our PNPLA3 RNA editing clinical candidate for liver disease. WVE-008 is on track to enter clinical development next year with the filing of a CTA. In addition to that, we are pioneering a new modality by uniting editing and silencing in a single oligonucleotide construct. With multiple planned clinical updates across our RNA editing and RNAi programs, Wave is in a unique position to unlock tremendous value from our robust RNA medicines pipeline.”
INLIGHT clinical study and target engagement update:
WVE-007 (GalNAc-siRNA): INHBE silencing approach designed to reduce fat while preserving muscle mass
| • | Wave’s INHBE program has a strong foundation in human genetics. People living with naturally low levels of INHBE have lower levels of unhealthy visceral fat, lower fasting glucose and triglycerides, and a lower risk of type 2 diabetes and cardiovascular disease. Silencing INHBE mRNA aims to reduce Activin E levels, thereby inducing fat loss without impacting muscle mass. |
| • | In Wave’s preclinical studies of mice with diet-induced obesity (DIO), single doses of GalNAc INHBE-siRNA led to potent and durable Activin E reductions of greater than 70%, and weight loss driven by reduction in visceral fat, without affecting muscle mass. Preclinical studies also support the use of INHBE GalNAc-siRNA as an add-on to GLP-1s or to curtail weight regain following cessation of GLP-1s. These reduced Activin E levels led to adipocyte shrinkage, fewer pro-inflammatory macrophages, less fibrosis, and improved insulin sensitivity in visceral adipose tissue, linking increased lipolysis to lower cardiometabolic risk. |
| • | Today, Wave announced highly significant, dose-dependent Activin E reductions were observed in the first three cohorts of its ongoing INLIGHT clinical trial evaluating WVE-007 (3:1 active: placebo). The trial is designed to address safety and tolerability as well as target engagement (Activin E reduction). One-month follow-up was available from Cohort 2 (240 mg) and Cohort 3 (400 mg), and six-month follow-up from Cohort 1. |
| • | At day 29 (one month post single dose), mean Activin E reductions from baseline were all highly significant (p<0.0001 for all doses): |
| • | Cohort 3 (400 mg): 85% reduction |
| • | Cohort 2 (240 mg): 75% reduction |
| • | Cohort 1 (75 mg): 56% reduction |
| • | The one-month reductions of Activin E observed in the 240 mg and 400 mg cohorts exceed levels that led to fat loss in preclinical models. |
| • | In Cohort 1 (75 mg), Activin E reductions were durable throughout the 6-month follow-up, supporting WVE-007’s potential for once or twice yearly doing. |
| • | WVE-007 is safe and well tolerated to date. An independent data monitoring committee supported dose expansion of the 600 mg cohort and dose escalation beyond that. |
| • | WVE-007 aims to achieve fat loss on par with semaglutide by six months of follow up post-single WVE-007 dose. |
| • | Next steps: Wave expects to deliver multiple clinical data updates from INLIGHT, including body composition and body weight: |
| • | 4Q 2025: anticipated three-month follow-up data from the expanded Cohort 2 (240 mg), as well as data from Cohort 1 (75 mg). |
| • | 1Q 2026: anticipated six-month follow-up data from Cohort 2 and three-month follow-up data from Cohort 3. |
| • | 2Q 2026: anticipated six-month follow-up data from Cohort 3 and three-month follow-up data from Cohort 4. |
Additional details can be found in the company’s Research Day presentation.
Additional updates from today’s presentation:
WVE-006 (RNA Editing): potential first- and best-in-class therapy for AATD that addresses both lung and liver manifestations of the disease
| • | The ongoing Phase 1b/2a RestorAATion-2 study is evaluating WVE-006, a GalNAc-conjugated RNA editing oligonucleotide, as a treatment for alpha-1 antitrypsin deficiency (AATD). The multidose portion of Cohort 2 is currently ongoing with monthly doses of 400 mg. Today, Wave announced Cohort 3 is now underway at doses of 600 mg of WVE-006. |
| • | In September 2025, Wave announced WVE-006 has already achieved key treatment goals by restoring protein levels associated with lower risk of AATD liver and lung diseases. Total AAT levels reached 13 µM, wild-type M-AAT protein accounted for 64% of circulating total AAT after treatment, with a corresponding reduction in Z-AAT. Notably, WVE-006 restored the ability to dynamically produce therapeutically relevant levels of AAT protein during an acute phase response, with an individual reaching over 20 µM AAT protein. |
| • | Next steps: 400 mg multidose cohort data expected in the first quarter of 2026; 600 mg single dosing is underway in the third and final cohort, with single and multi-dose data expected in 2026. |
WVE-008 (RNA Editing): potential first-in-class, disease modifying therapy for PNPLA3-I148M liver disease
| • | Building on the successful clinical translation of Wave’s RNA editing capability, the company has selected WVE-008 as its clinical candidate for PNPLA3-I148M liver disease. |
| • | There are an estimated 9 million homozygous PNPLA3-I148M individuals with liver disease in the U.S. and Europe. These homozygous carriers have a significantly higher risk of liver-related death compared to heterozygous carriers. Wave’s RNA editing approach aims to achieve at least 50% correction to restore the heterozygous phenotype with low risk of liver disease, similar to the approach with WVE-006. |
| • | Next steps: Wave expects to file a Clinical Trial Application (CTA) for WVE-008 in 2026. |
Wave’s platform innovations: extra-hepatic delivery and an emerging new modality
| • | Through chemistry optimization tailored to target and cell type, Wave is expanding its emerging pipeline of siRNAs (SpiNAs) and RNA editing oligonucleotides (AIMers) to both hepatic and extrahepatic tissues, including skeletal muscle, heart, adipose, and kidney. |
| • | Emerging modality adds capability to simultaneously edit and silence two unique targets with a single oligonucleotide construct. Wave presented preclinical data demonstrating that a single GalNAc-oligonucleotide construct upregulated LDLR protein and silenced PCSK9 mRNA. |
