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.

Boehringer Ingelheim GmbH terminated its second metabolic dysfunction-associated steatohepatitis (MASH) alliance on March 6, ending an $870 million license agreement inked with Yuhan Corp. for dual GLP-1/FGF21 agonist, BI-3006337 (YH-25724). Yuhan said March 7 that Boehringer, of Ingelheim, Germany, returned rights to YH-25724, a dual-acting glucagon-like peptide-1 and fibroblast growth factor 21 receptor agonist, based on the counterparty’s “strategic judgement” on developing MASH therapeutics.
