Wave Life Sciences Announces Initiation of Phase 2a Portion of INLIGHT™ Trial of WVE-007 (INHBE GalNAc-siRNA) for Obesity and Cardiometabolic Diseases
Rhea-AI Summary
Wave Life Sciences (Nasdaq: WVE) has initiated the Phase 2a multidose portion of the INLIGHT trial of WVE-007, an investigational INHBE GalNAc-siRNA, in individuals with obesity and comorbidities.
Phase 1 single-dose data showed 14% visceral fat, 5% total fat, and 3% waist reductions at six months, with safety up to 600 mg and potential once or twice-yearly dosing. Phase 2a will assess body composition, weight, liver fat, HbA1c, and lipids over 12 months and is expected to inform development in obesity, MASH, type 2 diabetes, and cardiovascular disease, with additional Phase 2 trials planned for 2H 2026.

- Phase 1: 14% visceral fat reduction at six months post-dose
- Additional Phase 1 reductions in total fat (5%) and waist (3%)
- Safety data support dosing of WVE-007 up to 600 mg
- Potential for once or twice-yearly WVE-007 dosing based on data
- Initiation of Phase 2a multidose INLIGHT trial in obesity
- Planned Phase 2 WVE-007 incretin combination trials in 2H 2026
Negative
- None.

In Phase 1 portion of trial, WVE-007 improved body composition by inducing fat loss, including harmful visceral fat, while maintaining muscle; data continue to support once or twice-yearly dosing
Phase 2a portion in individuals with higher BMI and body fat, with and without type 2 diabetes, includes multiple assessments to inform further development of WVE-007 in obesity as well as MASH, type 2 diabetes, and cardiovascular disease
Wave is on track to initiate additional Phase 2 trials in 2H 2026 evaluating WVE-007 in combination with incretins and as post-incretin maintenance
CAMBRIDGE, Mass., June 24, 2026 (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 it has initiated the Phase 2a multidose portion of the INLIGHT™ trial, a placebo-controlled (3:1) study evaluating WVE-007, an investigational GalNAc-siRNA, as monotherapy in individuals living with obesity with high BMI (35-50 kg/m2) and comorbidities.
The INLIGHT trial also includes an ongoing Phase 1 single dose portion investigating WVE-007 in otherwise healthy individuals living with overweight or obesity, with an average BMI of 32 kg/m2. In this portion of the trial, at six months of follow-up, a single 240 mg dose of WVE-007 continued to drive clinically meaningful reductions in visceral fat (-
“We have strong conviction in WVE-007’s potential to redefine obesity treatment and long-term cardiometabolic health, with early clinical results demonstrating a
The Phase 2a portion of the INLIGHT trial is expected to enroll participants across the U.S. and Europe and includes multiple assessments over a 12-month period, including body weight, waist circumference, body composition (MRI and DEXA), liver fat (MRI-PDFF), HbA1c, and lipid levels. The results will inform further development of WVE-007 in obesity, as well as MASH, type 2 diabetes, and cardiovascular disease.
Wave also expects to initiate new clinical trials evaluating WVE-007 as an incretin add-on and as post-incretin maintenance in the second half of 2026.
About WVE-007
WVE-007 is an investigational GalNAc-siRNA that utilizes Wave’s best-in-class proprietary oligonucleotide chemistry and the company’s Stereopure interfering Nucleic Acid (SpiNA) next generation siRNA design. WVE-007 is designed to silence INHBE mRNA, an obesity target with strong evidence from human genetics. Individuals who have a protective loss-of-function variant in one copy of the INHBE gene have a healthier body composition and cardiometabolic profile, including less visceral fat and lower risk of type 2 diabetes or cardiovascular disease. In preclinical models, INHBE GalNAc-siRNA led to adipocyte shrinkage, fewer pro-inflammatory macrophages, less fibrosis, and improved insulin sensitivity in visceral adipose tissue, supporting potential for metabolic improvement. As an add-on to semaglutide, Wave’s GalNAc-siRNA doubled weight loss in mice and prevented weight regain upon cessation of semaglutide.
About the INLIGHT™ Clinical Trial
The INLIGHT trial is an ongoing randomized, placebo-controlled (3:1) study that includes a Phase 1, single-ascending dose portion in otherwise healthy individuals living with overweight or obesity. This portion is designed to assess safety, tolerability, pharmacokinetics, and Activin E target engagement. The INLIGHT trial is currently ongoing at multiple trial sites, including in the U.S. A Phase 2a portion of the INLIGHT trial is evaluating multiple WVE-007 doses in individuals with high BMI, with and without type 2 diabetes, and will assess metabolic and body composition improvements as well as weight loss.
