STAT News: GLP-1 Pioneers DiMarchi and Tschöp Propose Dropping GLP-1 as a Drug Target for Obesity
Richard DiMarchi and Matthias Tschöp — whose work enabled Eli Lilly's Zepbound and the modern GLP-1 class — published a peer-reviewed draft paper arguing that targeting GIP and glucagon receptors alone, without GLP-1, may deliver comparable weight loss without the nausea and vomiting that plague current therapies. The experimental molecule, backed by BlueWater Biosciences, challenges the central dogma of obesity drug design. Results are preclinical and must still translate to humans.
