In what it says is the biggest obesity deal to date, Zealand Pharma A/S has signed up Roche AG to a potential $5.3 billion global collaboration and license agreement to develop petrelintide, an amylin analog that is currently in phase IIb development. The two companies will co-develop and co-commercialize petrelintide and combination products, including a fixed-dose combination of petrelintide and CT-388, Roche’s dual GLP-1/GIP receptor agonist.

Abbvie Inc. is buying into the obesity fray in a potential $1.875 billion development and commercialization agreement with Danish peptide drug discovery specialist Gubra A/S. In addition, there will be a $350 million up-front payment as Abbvie takes over the reins of GUB-014295 (referred to as Gubamy), a long-acting analog of the satiety hormone amylin, currently in phase I development.
