One crucial observation made in the early clinical trials with GLP-1RA was that treated patients consistently lost weight relative to controls receiving placebo

For weight loss, the main options are Wegovy (semaglutide), Saxenda (liraglutide), and Mounjaro (tirzepatide)

46 The mainstream view holds that the canonical GLP-1 receptor is not expressed in the human liver, and any hepatic effects are likely mediated through extrahepatic mechanisms rather than direct action

This example demonstrates how acquisition can shortcut capacity growth, but at the cost of a complex transfer and harmonization process
