ABSTRACT
The identification of amylin as a glucoregulatory peptide hormone with roles in meal-ending satiation sparked a surge of experimental development, which culminated in the amylin mimetic drug pramlintide. Pramlintide was approved by the FDA in 2005 for the treatment of type 1 diabetes mellitus and insulin-requiring type 2 diabetes, and was also explored as a novel anti-obesity treatment. Despite this exciting potential, efforts to develop an amylin-based anti-obesity therapeutic stalled owing to challenges around dosage frequency, safety and formulation. Generally, anti-obesity therapies have displayed modest efficacy and mixed safety profiles, leaving a clear unmet clinical need that requires addressing. Advances in peptide chemistry have reinvigorated the amylin field by enabling the manufacture of effective new amylin-based molecules, resulting in therapeutics that are now on the cusp of approval. At present, there are growing concerns around GLP1 receptor agonist-based therapeutics, in particular their association with loss of lean body mass. Additionally, treatment of patients with overweight or obesity without associated comorbidities is increasingly common. The widespread pharmacotherapy of otherwise healthy populations with overweight or obesity with the goal of improving future health requires further regulatory and ethical consideration. This Review describes how amylin controls energy homeostasis and provides a current overview of amylin-based therapeutic development.
