Summary

Efruxifermin (BMS‑986089) is a long‑acting Fc‑fusion analog of fibroblast growth factor‑21 designed for metabolic diseases such as non‑alcoholic steatohepatitis (NASH) and type‑2 diabetes.

Mechanism of Action

Binds to the FGFR1c/KLB receptor complex, activating downstream signaling that improves insulin sensitivity, reduces hepatic lipogenesis, and enhances fatty‑acid oxidation.

Routes of Administration

Subcutaneous
