WVE-007 induces fat loss without muscle loss, with clinical data supporting 1-2x per year dosing; preclinical data demonstrate Wave's INHBE GalNAc-siRNA in combination with GLP-1 doubled weight loss compared with GLP-1 alone
Maintenance clinical trial evaluating WVE-007's ability to curtail weight regain after incretin cessation on track to initiate 2H 2026
CAMBRIDGE, Mass., Sept. 23, 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 the initiation of its Phase 2a clinical trial evaluating WVE-007, an investigational GalNAc-siRNA, in combination with tirzepatide in adults living with obesity.
"This combination trial of WVE-007 with weekly tirzepatide marks an important milestone in our development plan to advance WVE-007 across three distinct obesity treatment settings: monotherapy, combination therapy, and as a post-incretin maintenance therapy to prevent weight recurrence," said Christopher Wright, MD, PhD, Chief Medical Officer at Wave Life Sciences. "Our preclinical data, as well as emerging clinical data in the field, support the potential for enhanced fat loss and preservation of muscle with WVE-007 as compared to incretins alone. The consequence of muscle loss is particularly important since beyond strength, skeletal muscle also plays an important role in both metabolism and weight maintenance. In our clinical data to date, we have demonstrated a differentiated profile for WVE-007, with potential for best-in-class INHBE silencing, favorable safety and tolerability, and once- or twice-yearly dosing."
The INLIGHT clinical program is evaluating WVE-007 as a monotherapy and in combination with tirzepatide as a treatment for obesity and other cardiometabolic indications, including MASH. The placebo-controlled (3:1) Phase 2a combination trial will evaluate 240 mg and 400 mg doses of WVE-007 in combination with weekly tirzepatide in individuals living with obesity (BMI 35-50 kg/m2) and type 2 diabetes. The INLIGHT clinical program also includes an ongoing Phase 2a monotherapy trial, which includes multiple assessments over a 12-month period, and these results will inform further development of WVE-007 in obesity, as well as MASH, type 2 diabetes, and cardiovascular disease.
Wave also remains on track to initiate a clinical trial of WVE-007 as a maintenance therapy to preserve weight loss following discontinuation of incretin treatment in the second half of 2026.
Wave previously presented preclinical data at ObesityWeek® 2025 demonstrating that WVE-007 has potential for use synergistically with GLP-1s as well as to curtail weight regain after the cessation of treatment with GLP-1.
