Researchers at the University of Copenhagen have identified a signaling pathway that simultaneously increased energy expenditure and decreased food intake. In both human and primate studies, agonists of the tachykinin NK2 receptor (NK2R) led to both decreased food intake and increased energy expenditure. And in behavioral tests, they were not aversive, suggesting they do not cause the nausea that is a major side effect of GLP-1 agonists.

But given the lateness of the day in the Biden administration, the proposal may be more symbolic than historic.

Sales balloon for GLP-1 drugs from Novo Nordisk, Eli Lilly

Nearly $3.8 billion was earned by Novo Nordisk A/S and Eli Lilly and Co. in the third quarter for their glucagon-like peptide-1 (GLP-1) drugs to treat obesity. Novo’s GLP-1 drug, Wegovy (semaglutide), approved by the U.S. FDA in June 2021, had sales of DKK17.3 billion (US$2.5 billion), while Lilly’s Zepbound (tirzepatide), which is a GLP-1 and glucose-dependent insulinotropic polypeptide dual agonist FDA-approved in November 2023, posted sales of $1.26 billion for the quarter.
