Further Reading
The SELECT trial, presented at the American Heart Association 2023 Scientific Sessions, has provided significant insights into the cardiovascular benefits of semaglutide, a GLP-1 receptor agonist popular for its weight loss effects. This trial, involving 17,000 participants without type 1 or type 2 diabetes but with obesity or overweight and at least one weight-related comorbidity, aimed to assess the cardiovascular outcomes of semaglutide 2.4 mg (Wegovy) compared to a placebo, alongside optimal lifestyle management.
The primary outcome focused on a composite of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke. The results were promising, showing a primary outcome event in 6.5% of the semaglutide group compared to 8.0% of the placebo group, indicating a 20% reduction in risk (HR, 0.80; 95% CI, 0.72 to 0.90; P<.001). Secondary outcomes hinted at nonsignificant trends towards benefits in cardiovascular death, heart failure hospitalization or urgent medical visit, all-cause mortality, and an HbA1c of 6.5% or greater.
The trial's findings suggest that the cardiovascular benefits observed with semaglutide are not solely attributable to weight reduction. This revelation has sparked considerable interest, as it indicates a potential shift in the management of cardiovascular risk factors, particularly in individuals with obesity or overweight but without diabetes. The SELECT trial stands as the largest and longest study of its kind, offering a new perspective on the role of GLP-1 receptor agonists in cardiovascular health.
The growing popularity of GLP-1 receptor agonists like semaglutide, evidenced by their increasing use for weight loss and glycemic control, underscores the importance of such trials in understanding the full scope of their benefits and potential applications. While semaglutide has been celebrated for its efficacy in weight management, the SELECT trial's findings broaden its appeal by highlighting its cardiovascular advantages, thereby reinforcing the drug's position in the treatment paradigms for obesity and related conditions.

Carmot Therapeutics is at the forefront of developing innovative treatments for metabolic diseases, including obesity and type 2 diabetes, through a deep understanding of incretin signaling and signaling bias. Their research focuses on the design of novel incretin agonists that could significantly impact weight loss and glycemic control.
The Science Behind Incretin Signaling
Incretins, specifically GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide), play a crucial role in metabolic regulation. These hormones interact with G protein-coupled receptors (GPCRs) on cell surfaces, triggering a cascade of events that ultimately influence blood sugar levels and weight. Upon binding to their respective receptors, GLP-1 and GIP activate the cyclic adenosine monophosphate (cAMP) signaling pathway, a critical process for glucose regulation and insulin secretion. However, this activation also recruits ß-arrestin, which can dampen the signaling over time through receptor internalization and desensitization.
Carmot's research has led to the development of biased GLP-1 receptor agonists. These specially designed molecules preferentially activate the cAMP pathway while minimizing ß-arrestin recruitment. This selective activation is believed to result in prolonged glucose-lowering effects and weight loss, offering a promising therapeutic strategy for managing obesity and type 2 diabetes.
The Potential of Biased Signaling
By focusing on biased signaling, Carmot aims to enhance the therapeutic benefits of incretin agonists. The idea is to maintain prolonged pharmacological activity by reducing receptor desensitization and internalization. This approach could offer advantages over traditional GLP-1 and GIP receptor agonists, potentially leading to better outcomes for patients with metabolic diseases.
The Road Ahead: Clinical Development and Regulatory Considerations
Carmot has two drug candidates in phase 2 and one in phase 1 clinical trials, targeting various aspects of metabolic disease management. These trials are crucial steps in evaluating the safety, efficacy, and optimal dosing of these novel therapeutics.
However, it's important to understand the limitations and uncertainties at this stage of drug development. Before a drug can be considered for approval by the FDA, it must successfully complete phase 3 trials, which are designed to provide more definitive efficacy data and further assess safety in a larger patient population. Phase 2 results, while promising, are preliminary and cannot fully predict the outcome of later-stage trials or regulatory approval processes.
Carmot Therapeutics' work on incretin receptor signaling bias represents a promising avenue for developing new treatments for obesity and type 2 diabetes. Their approach, focusing on biased signaling to enhance therapeutic effects, could lead to significant advancements in managing these conditions. However, the potential of these drug candidates will be more clearly defined as they progress through the clinical development pipeline and undergo rigorous evaluation in phase 3 trials and beyond.
As we await further data, it's crucial for patients, healthcare providers, and stakeholders to maintain a balanced perspective on the potential benefits and limitations of these emerging therapies.
