Trial Type	Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
New Combination	NCT00151697 ↗	LANN-study: Lantus, Amaryl, Novorapid, Novomix Study	Completed	Rijnstate Hospital	Phase 3	2005-05-01	Many diabetics gain weight while on insulin therapy. In this study, we evaluate the efficacy of the combination of glimepiride and short-acting insulin on weight control and glucose control. In this study, 150 diabetics whose diabetic control is inadequate while on maximal oral treatment will be randomized to either the new combination treatment or twice daily injections with a mixture of short- and longacting insulin or once-daily injection with a basal insulin analog. The study will compare glucose control and weight gain during a year after randomisation between the three treatments.

Clinical Trials Update, Market Analysis, and Projection for Glimepiride

Last updated: January 26, 2026

Summary

Glimepiride, a third-generation sulfonylurea, remains a key oral hypoglycemic agent for type 2 diabetes management. Approved by FDA in 1995, it works by stimulating insulin secretion from pancreatic beta cells. Recent developments include ongoing clinical evaluations of its combined use with other agents and novel formulations aimed at improving efficacy and safety. The global market for Glimepiride is driven by increasing diabetes prevalence, especially in emerging economies. Market forecasts predict steady growth with compound annual growth rates (CAGR) of approximately 3-5% through 2028. This report provides a detailed review of current clinical trials, market dynamics, competitive landscape, and future projections ensuring industry stakeholders are well-informed.
