Mechanism of Action
Key takeaways
- Lixisenatide is a GLP-1 receptor agonist combined with insulin glargine in the approved product Soliqua 100/33.
- It is indicated as an adjunct to diet and exercise for glycemic control in adults with type 2 diabetes.
- The combination is not recommended with other GLP-1 receptor agonist products or for diabetic ketoacidosis.
- More than 75 registered trials have studied lixisenatide, including completed phase 3 and phase 4 studies.
- FAERS reports for products containing lixisenatide most often involve blood glucose changes and product handling issues, not necessarily drug-caused effects.
What Lixisenatide Is
Lixisenatide is a glucagon-like peptide-1 (GLP-1) receptor agonist. In the approved product Soliqua 100/33, it is paired with insulin glargine, a long-acting insulin analog. Insulin glargine lowers blood glucose by promoting glucose uptake into muscle and fat tissue and by reducing glucose production in the liver. Insulin also suppresses the breakdown of fat and protein. Lixisenatide works through the GLP-1 receptor pathway, complementing insulin's glucose-lowering action.
What Lixisenatide Is Approved For
Soliqua 100/33, the combination of insulin glargine and lixisenatide, is approved as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. The label states that combining this product with another GLP-1 receptor agonist is not recommended. It is also not recommended for treating diabetic ketoacidosis, and it has not been studied alongside prandial insulin. The current label does not carry a boxed warning.
What the Evidence Shows
Lixisenatide has been studied in more than 75 registered clinical trials. One completed phase 3 trial assessed its efficacy and safety in patients with type 2 diabetes who had insufficient control on basal insulin, with or without metformin. A separate completed phase 4 trial examined the combination product alongside sulfonylurea as an add-on to basal insulin in patients who chose to fast during Ramadan. Another completed phase 3 trial compared the iGlarLixi combination against IDegAsp in participants in China following oral antidiabetic drugs.
Reported Side Effects
Reports submitted to FAERS for lixisenatide-containing products most frequently describe increases in blood glucose, with 467 reports. A substantial share of reports relate to product handling rather than a direct drug effect, including storage errors (402), off-label use (355), accidental exposure to the product (340), exposure via skin contact (203), and inappropriate dosing schedules (149). Gastrointestinal and visual symptoms were also reported, including nausea (154) and visual impairment (146). These figures reflect the number of reports submitted, not confirmed incidence or a proven causal link to the drug.
