GSK buys liver disease drug

GSK acquires efimosfermin, a drug candidate for the liver disease MASH, from Boston Pharmaceuticals for USD 1,2 billion. The drug is ready for Phase III studies and, if all goes well, could be launched in 2029. The agreement includes up to USD 800 million in milestone payments. Efimosfermin, a monthly injection, has shown promising results in reducing liver fibrosis and GSK plans to develop the drug for alcoholic liver disease.
