Denmark’s Novo Nordisk saw its shares rise as much as 13% to 659.20 kroner this morning, after it announced top-line results from a Phase Ib/IIa clinical trial with amycretin once weekly subcutaneous (SC) administration.

Amycretin could give Novo a buzzy product in a newly competitive obesity market. It works similarly to existing GLP-1 products by mimicking a hormone in the body that provides a satiated feeling, which curbs hunger, but adds a different hormone in the pancreas.
