GSK is acquiring efruxifermin alfa from Boston Pharmaceuticals for up to $2 billion, including $1.2 billion upfront and $800 million in milestone payments. The FGF21 analogue therapy, originally developed by Novartis, targets metabolic dysfunction-associated steatohepatitis (MASH) and alcohol-related liver disease (ALD).
Phase 2 data showed significant reversal of liver fibrosis, improvements in glucose and triglycerides, and strong tolerability. The once-monthly injectable will now join GSK’s internal pipeline alongside GSK532990, an investigational siRNA for liver conditions. Commercial launch is expected by 2029.
