Petrelintide

Petrelintide (development name ZP8396) is an amylin analogue dosed once weekly, developed by Zealand Pharma for the treatment of type 2 diabetes and obesity. Preclinical data suggests it may be more effective in combination with semaglutide. In June 2024 the company announced results for a Phase 1b trial, which found 8.6 percent weight loss over 16 weeks.

In March 2025, Roche entered into an exclusive collaboration and licensing agreement with Zealand Pharma to co-develop and co-commercialise petrelintide as a potential foundational therapy for overweight and obese people. This development would focus on petrelintide, both as a standalone therapy and in a fixed-dose combination with CT-388 for overweight and obese people.
