Abstract
From the pioneering moment in 1987 when the insulinotropic effect of glucagon-like peptide 1 (GLP-1) was first demonstrated in humans, to today's pharmaceutical gold rush for GLP-1-based treatments of obesity, the journey of GLP-1 pharmacology has been nothing short of extraordinary. The sequential conceptual developments of long-acting GLP-1 receptor (GLP-1R) mono-agonists, GLP-1R/glucose-dependent insulinotropic polypeptide receptor (GIPR) dual-agonists, and GLP-1R/GIPR/glucagon receptor (GcgR) triple agonists, have led to profound body weight-lowering capacities, with benefits that extend past obesity and towards obesity-associated diseases. The GLP-1R/GIPR dual-agonist tirzepatide has demonstrated a remarkable 23% body weight reduction in individuals with obesity over 72 weeks, eclipsing the average result achieved by certain types of bariatric surgery. Meanwhile, the GLP-1R/GIPR/GcgR triple-agonist retatrutide achieves similar body weight loss (∼25%) in just two-thirds of the time, potentially surpassing the efficacy of Roux-en-Y gastric bypass. These remarkable achievements rightfully raise the question whether and why there is still need for novel anti-obesity medications (AOMs) in the future.
