Wave Life Sciences Stock Rockets 120% After Obesity Drug Shows Deep Fat Reduction, Muscle Gain — Traders See A ‘Blockbuster' Candidate

Wave jumped after WVE-007 showed clear fat loss, lean-mass gains, durable biomarker effects, and good tolerability.

• Single-dose results showed clear shifts in visceral fat, total fat, and lean mass at three months.
• Activin E levels dropped sharply and remained suppressed through Day 85.
• WVE-007 was generally well tolerated with no severe or serious adverse events reported.

Shares of Wave Life Sciences (WVE) jumped over 120% on Monday after the company released positive interim results from its Phase 1 INLIGHT trial evaluating WVE-007, an investigational INHBE-targeting GalNAc-siRNA for obesity.

Results At Three Months

Wave said that a single 240 mg dose of WVE-007 produced clear changes in body composition by the three-month check. On average, participants saw a 9.4% drop in visceral fat, a 4.5% reduction in total body fat, or 3.5 lbs, and a 3.2% increase in lean mass, or 4 lbs. In the placebo group, the corresponding changes were a 0.2% decrease in visceral fat, a 0.5% decrease in total body fat, and a 2.3% increase in lean mass.

The company highlighted consistent and durable suppression of serum Activin E, with maximum reductions of 78% observed 43 days after dosing and mean reductions above 75% maintained through Day 85. Wave said the durability of these reductions supports a potential dosing schedule of once or twice per year.

Wave described WVE-007 as generally safe and well tolerated up to 600 mg. There were no discontinuations or severe or serious treatment-emergent adverse events. All treatment-related events were mild. There were no clinically meaningful changes from baseline in lipid profiles or liver function tests.

Genetic Rationale 

Wave noted that individuals with a natural loss-of-function variant in one copy of the INHBE gene tend to have healthier body composition, lower visceral fat, and reduced risk of type 2 diabetes and cardiovascular disease. The company said this human genetics foundation supports the therapeutic potential of WVE-007.

Phase 2 Planning 

The company said that planning was ongoing for Phase 2 studies evaluating WVE-007 as a monotherapy, as an add-on to incretin therapies and as a maintenance therapy after stopping incretin treatment. More clinical updates are expected in the first quarter of 2026, including six-month data from the 240 mg cohort and three-month data from the 400 mg cohort.

Wave also said that in the second quarter of 2026, it expects to report six-month follow-up data from the 400 mg single-dose cohort and three-month follow-up data from the 600 mg single-dose cohort.

Analyst Takes

Leerink called the update “an exciting first look,” saying the data build on Wave’s prior Activin E reductions and show the preclinical findings are “translating very nicely,” while maintaining an 'Outperform' rating. 

Jefferies said the lowest-dose data met its base case and offered “incremental confidence” for later readouts, reiterating its 'Buy' rating and $26 target. Truist said the results “fundamentally" improve the obesity landscape outlook and validate Wave’s siRNA platform, keeping a 'Buy' rating and $36 target.
