Hormonal

The dual GLP-1R/GCGR agonist BI 456906 produces clinically meaningful body weight loss (up to 13.8% over 16 weeks) in adults with overweight/obesity, driven by target engagement at both receptors.

BI 456906 is a once-weekly injection for people with overweight or obesity that works by targeting two hormones (GLP-1 and Glucagon). In early studies, it led to significant weight loss (nearly 14% over 4 months). The main side effects are gastrointestinal (nausea, vomiting), which are common but often manageable. It is designed for people who may not achieve sufficient weight loss with single-target therapies.

Why this rating

Phase I clinical trial in healthy volunteers and overweight/obese adults; safety and efficacy data are present but sample sizes are small (N=24 and N=125) and duration is short (16 weeks).
