Abstract:
Type 2 diabetes mellitus (T2DM) is a complex, progressive disease affecting an estimated 257 million people worldwide. A number of unmet needs exist with traditional T2DM therapies, which can lead to insufficient glycaemic control and increased risk of diabetes-associated complications. An emerging class of diabetes therapeutics, the glucagon-like peptide-1 (GLP-1) receptor agonists, appear to address many of the unmet needs of patients with T2DM. This review summarises the recent findings and current clinical guidelines of the currently approved GLP-1 receptor agonists and explores the new GLP-1 receptor agonists in development. It also concentrates on the physiological basis for early use of GLP-1 receptor agonists, their use as an alternative to insulin therapy, the rationale for combining them with insulin and their cost-effectiveness.
Insights
Glucagon-like peptide-1 (GLP-1) receptor agonists offer new hope for managing type 2 diabetes, addressing unmet needs in glycaemic control and reducing complication risks. This review explores their current and future roles in diabetes therapy.
Area of Science:
- Endocrinology and Metabolism
- Pharmacology
- Diabetes Research
Background:
- Type 2 diabetes mellitus (T2DM) affects millions globally, with significant unmet needs in current treatment paradigms.
- Traditional T2DM therapies often result in suboptimal glycaemic control and elevated risks of diabetes-related complications.
- Emerging therapeutic classes, such as GLP-1 receptor agonists, show promise in addressing these limitations.
Purpose of the Study:
- To review current clinical guidelines and recent findings on approved glucagon-like peptide-1 (GLP-1) receptor agonists.
- To explore novel GLP-1 receptor agonists currently under development.
- To examine the physiological rationale for early GLP-1 receptor agonist use, their role as insulin alternatives, combination therapy potential, and cost-effectiveness.
Main Methods:
- Comprehensive literature review of recent findings and clinical guidelines.
- Analysis of physiological mechanisms underlying GLP-1 receptor agonist action.
- Evaluation of evidence regarding therapeutic positioning, including early use, insulin substitution, and combination strategies.
Main Results:
- Approved GLP-1 receptor agonists demonstrate efficacy in improving glycaemic control and addressing unmet needs in T2DM management.
- New GLP-1 receptor agonists in development offer potential for enhanced efficacy and expanded therapeutic options.
- Evidence supports the use of GLP-1 receptor agonists as an alternative to or in combination with insulin therapy, with considerations for cost-effectiveness.
Conclusions:
- GLP-1 receptor agonists represent a significant advancement in T2DM therapeutics, addressing key limitations of traditional treatments.
- The review highlights the evolving landscape of GLP-1 receptor agonists, from current approved agents to promising future developments.
- Strategic implementation, including early use and combination therapy, alongside cost-effectiveness analyses, will be crucial for optimizing patient outcomes in T2DM.
