One of Novo Nordisk's next-generation obesity shots to follow up on the success of Wegovy helped patients lose 22% of their weight in 36 weeks, according to early-stage trial results on Friday, boosting the drugmaker's shares.

The new treatment targets gut hormone GLP-1 but also mimics amylin, a hormone released by the pancreas that suppresses hunger.

Novo Nordisk shares jumped on Friday as the Danish drugmaker said an experimental drug was able to reduce weight by as much as 22%.
