Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00118950 ↗	Effect of Metformin Versus Repaglinide Treatment in Non-Obese Type 2 Diabetic Patients Uncontrolled by Diet	Completed	Steno Diabetes Center	Phase 4	2001-03-01	Background: Metformin is the first drug of choice in obese patients with type-2 diabetes (T2DM) due to its antiglycaemic as well as its cardiovascular protective potentials. In non-obese T2DM patients insulin-secretagogues are empirically used as first choice. The aim of this study was to evaluate the effect of metformin versus an insulin-secretagogue, repaglinide on glycaemic regulation and non-glycaemic cardiovascular risk markers in non-obese patients with T2DM. Methods: Single-center, randomised, double-masked, double-dummy, cross-over-study of 96 non-obese (BMI ≤ 27 kg/m2) Caucasian T2DM-patients. After a one month run-in on diet-only treatment, patients were randomised to either repaglinide 2mg three times a day (t.i.d). followed by metformin 1g twice a day (b.i.d.) or vice versa each for a period of four months with a one month wash-out between interventions.

NCT00118963 ↗	Effect of Repaglinide Versus Metformin Treatment in Non-Obese Patients With Type-2-Diabetes	Completed	Steno Diabetes Center	Phase 4	2003-01-01	Aim: The United Kingdom Prospective Diabetes Study (UKPDS) showed a reduction in cardiovascular events in obese patients with type-2-diabetes treated with metformin compared with other hypoglycaemic treatments with no difference in glycemic control between treatments. Non-obese patients with type-2-diabetes are usually treated with insulin-secretagogues or insulin when diet fails. Since non-obese patients with type-2-diabetes also carry a high risk of cardiovascular events, the use of metformin for this sub-group of patients might be more beneficial. Moreover, when insulin-treatment is initiated ongoing oral hypoglycaemic agents (OHA) are often continued, but in non-obese patients with type-2 diabetes little evidence exist for choosing the optimal class of OHA to be combined with insulin. The aim of the project is therefore to investigate the effect of metformin vs. an insulin-secretagogue (repaglinide) in combination with insulin on glycemic control and non-glycemic cardiovascular risk-factors in non-obese patients with type-2-diabetes, uncontrolled on diet alone. Methodology: Single-center, double-blind, double-dummy, randomized, parallel study involving 100 non-obese (BMI 27 kg/m2 or lower) patients with type-2-diabetes investigating the effect of treatment with metformin vs. repaglinide each in combination with biphasic insulin (Insulin-aspart 30/70, BIAsp30) for a period of 12 months.

NCT00399711 ↗	Effect of Repaglinide and Metformin Combination Tablet or Rosiglitazone and Metformin in Fixed Dose Combination on Blood Glucose Control in Patients With Type 2 Diabetes	Completed	Novo Nordisk A/S	Phase 3	2006-11-01	This trial is conducted in the United States of America (USA). This trial compares the changes in HbA1c after 26 weeks of repaglinide and metformin fixed dose combination tablet given as twice daily versus three times daily regimens or versus twice daily rosiglitazone and metformin fixed dose combination tablet in subjects with type 2 diabetes currently on monotherapy.
NCT00491725 ↗	Efficacy and Safety of Repaglinide and Metformin Combination Therapy in Type 2 Diabetes Failing on Oral Anti-diabetic Drugs	Completed	Novo Nordisk A/S	Phase 4	2005-09-01	This trial is conducted in Asia. The aim of this trial is to evaluate the efficacy and safety of repaglinide and metformin combination therapy in Chinese subjects with type 2 diabetes inadequately controlled with OAD (oral anti-diabetic drugs).

5. FAQs

Q1: What are the main benefits of combining repaglinide with metformin?

A1: The combination offers complementary mechanisms—repaglinide stimulates rapid insulin release post-meal, while metformin reduces hepatic glucose production and improves insulin sensitivity. This dual action enhances glycemic control, reduces postprandial spikes, and can simplify treatment regimens.

Q2: What are the primary safety concerns associated with repaglinide and metformin combination therapy?

A2: The main risks include hypoglycemia (less common with repaglinide but still possible), lactic acidosis (rare but serious with metformin, especially in renal impairment), and gastrointestinal disturbances. Proper patient selection and monitoring mitigate these risks.

Q3: How does recent clinical trial data influence the future adoption of this combination?

A3: Positive outcomes such as sustained HbA1c reductions, low adverse events, and cardiovascular safety support broader adoption. Ongoing trials focusing on long-term safety and specific populations may further improve confidence among clinicians.

Q4: What market segments are most poised for expansion for this drug?

A4: Developing countries with rising diabetes prevalence, elderly populations requiring simplified regimens, and healthcare systems emphasizing cost-effective therapies.

Q5: How do regulatory agencies impact the development and approval of repaglinide and metformin formulations?

A5: Agencies like the FDA and EMA prioritize safety, efficacy, and quality, requiring robust clinical data. Recent approvals of fixed-dose combinations facilitate market entry, while post-market surveillance ensures ongoing safety assessment.

6. Key Takeaways

• Clinical Efficacy & Safety: Recent trials confirm the combination’s robust hypoglycemic efficacy with a favorable safety profile, especially when appropriately monitored.
• Market Dynamics: The global market for oral antidiabetics continues to expand, with fixed-dose combinations gaining preference due to improved adherence and convenience.
• Growth Drivers: Increasing diabetic prevalence, regulatory support, and technological innovation underpin future market expansion.
