Abstract

Obesity, type 2 diabetes, and the numerous associated metabolic co-morbidities are growing global threats to public health. Despite recent progress in pharmacotherapies for metabolic diseases, the current treatment options have limited efficacy and provide mostly symptomatic relief with little or no impact on disease reversal. Thus, improved therapies are urgently needed. As a result, the scientific community has increasingly invested in leveraging new pathophysiological insights into more efficacious pharmacotherapies for metabolic complications. A heightened understanding of the large, interindividual variation in responsiveness to certain metabolic medicines combined with advances in engineering multi-agonist candidates are important steps towards this goal. Additionally, the emerging pharmacological concept of peptide-mediated targeting of small molecules for tissue-specific delivery holds promise for more powerful treatment solutions in the future. In this review, we summarize recent advances in medicinal chemistry and molecular pharmacology that have enabled the engineering of several, novel, poly-agonist drug candidates for treatment of metabolic diseases, and we discuss the recent results from clinical trials assessing the efficacy and safety of glucagon-like peptide (GLP)-1/glucagon and GLP-1/GIP co-agonists.
