Merck Partners with Hansoh to Enter Oral GLP-1 Obesity Drug Market with $2 Billion Deal

In a strategic move to expand its presence in the obesity treatment market, Merck has formed a partnership with Chinese biotech company Hansoh Pharma to develop an oral GLP-1 receptor agonist pill, known as HS-10535[1][2]. Merck will pay Hansoh $112 million upfront, with additional payments potentially reaching $1.9 billion as specific clinical, regulatory, and commercial milestones are achieved[1]. While Merck will hold rights to develop and commercialize the drug outside China, Hansoh retains the option to co-promote or exclusively commercialize it within China[2]. This deal marks Merck’s first significant venture into obesity therapies and underscores the company's interest in diversifying its pharma portfolio beyond its leading oncology product, Keytruda[1][2].
