WVE shares fell to their lowest levels in more than 10 months and cracked the crucial 200-day moving average (200-DMA) for the first time since Dec. 8, 2025.

Overall Weight Loss Was Modest

At the six-month mark, patients receiving a 240 mg dose saw a 14% reduction in visceral fat, a 5% reduction in total fat, and a 3% decrease in waist circumference. However, total body weight declined by just 1%, a figure that fell short of retail expectations in a highly competitive obesity drug market.

The company said there were 32 participants in the 240 mg trial. WVE-007 is an investigational RNA-based drug to silence the INHBE gene to help reduce fat and improve metabolism.

Wave Life Sciences plans to begin a Phase 2a study of WVE-007 in the second quarter of 2026. The study will track weight, fat levels, and other health markers over 12 months. The company said it expects to see greater fat loss while preserving muscle.
