The growing prevalence of obesity has spurred intensive research into novel therapeutic agents capable of addressing this complex health issue. Among the most promising are peptides, which offer targeted mechanisms for metabolic regulation. Cagrilintide, an investigational peptide from Novo Nordisk, stands out as a significant development in this field, acting as a potent amylin analog with dual receptor activity.

Cagrilintide's primary mechanism of action centers on its role as a long-acting amylin analog. Amylin, a hormone naturally produced by the pancreas, plays a vital role in regulating blood glucose levels and promoting satiety after meals. It does this by slowing gastric emptying and inhibiting glucagon secretion, both of which contribute to reduced food intake and better glycemic control. Cagrilintide is engineered to mimic these beneficial actions, offering a more stable and prolonged effect compared to natural amylin, making it a valuable tool in obesity treatment.

Furthermore, Cagrilintide acts as a dual amylin and calcitonin receptor agonist. This means it can bind to and activate both amylin receptors (AMYR) and calcitonin receptors (CTR). The interaction with amylin receptors primarily influences appetite control, leading to enhanced satiety and reduced food cravings. The role of the calcitonin receptor in glucose metabolism is also an area of active investigation, potentially contributing to Cagrilintide's overall metabolic benefits.

The development of Cagrilintide involves sophisticated peptide modifications designed to enhance its stability and in vivo presence. For instance, specific amino acid substitutions are made to minimize amyloid fibril formation, a common issue with amylin analogs. Additionally, the incorporation of a C-20 fatty diacid prolongs its duration of action by binding to albumin in the bloodstream. These technical advancements ensure that Cagrilintide can be administered effectively, often weekly, and maintain its therapeutic effects.

Clinical studies, including those involving combination therapy with semaglutide, have provided compelling evidence of Cagrilintide's efficacy in driving substantial weight loss. In these trials, Cagrilintide has been shown to significantly reduce body weight and improve metabolic markers. The ability of Cagrilintide to enhance satiety and reduce caloric intake makes it a key component in the pharmacological management of obesity.
