NCT00576784 ↗	Metabolic Effects of Pioglitazone in Type II Diabetic Patients Previously Treated With Insulin	Completed	IKFE Institute for Clinical Research and Development	Phase 4	2005-04-01	The goal of the study is to demonstrate whether a switch from insulin therapy to an oral therapy with pioglitazone/glimepiride will lead to a deterioration of glycemic control (increase in HbA1c by more than 0.5 %) within a 6 month observation period.
NCT00700856 ↗	Thiazolidinediones Or Sulphonylureas and Cardiovascular Accidents.Intervention Trial	Unknown status	Associazione Medici Diabetologi (AMD)	Phase 4	2008-09-01	Background: In patients with type 2 diabetes inadequately controlled with metformin, two main therapeutic options are equally plausible: add-on a sulfonylurea (SU) or a thiazolidinedione (TZD). Since the two classes of drugs clearly differ in terms of mechanisms of action, side effects, economic costs and cardiovascular risk factors profile, a direct comparison of the two therapeutic strategies would be most appropriate. Aims: 1) To evaluate the effects of add-on pioglitazone as compared with add-on a SU on the incidence of cardiovascular events in type 2 diabetic patients inadequately controlled with metformin; 2) To compare the two treatments in terms of glycemic control, safety, and economic costs. Methods: multicentre, randomised, open label, parallel group trial of 48 months duration. Eligible participants (type 2 diabetic males and females, aged 50-75 years, BMI 20-45 Kg/m2, in treatment for the last two months with metformin 2 gr/die in monotherapy and with HbA1c > =7.0% and 8.0 % on two consecutive occasions will lead to addition of insulin to ongoing oral therapy. Primary efficacy outcome: a composite endpoint of all-cause mortality, non fatal MI (including silent MI), non fatal stroke, and unplanned coronary revascularization. Secondary outcomes. Principal secondary outcome: a composite ischemic endpoint of sudden death, fatal and non fatal acute MI (including silent MI), fatal and non fatal stroke, major amputations (above ankle), endovascular or surgical intervention on the coronary, leg or carotid arteries. Other secondary outcomes - a composite cardiovascular end point including the primary end point plus hospitalization for heart failure, endovascular or surgical intervention on the coronary, leg or carotid arteries, silent MI, angina - by WHO criteria and confirmed by a new electrocardiogram abnormality - intermittent claudication with an ankle/brachial index lower than 090; events of heart failure; a microvascular endpoint including: plasma creatinine increase of 2 times above the baseline value or creatinine clearance reduction of 20ml/min/1. 73m2 or development of overt nephropathy (dialysis or plasma creatinine >3,3 mg/dl) or macroalbuminuria; glycemic control (changes from baseline in HBA1c, time to failure of glycemic control, i.e., HBA1c >8.0% on two consecutive occasions three months apart); major CV risk factors (lipids, blood pressure, microalbuminuria, inflammation markers, waist circumference); safety and side effects; direct and indirect costs. Data regarding CV endpoints, safety, tolerability, and study conduct will be monitored and analyzed by an independent committee, and will be not available to the study investigators until the closing of data collection. Efficacy end points will be analyzed on an intention-to-treat basis.

Clinical Trials Update

Ongoing and Recent Clinical Studies

Recent years have witnessed increased research interest in Pioglitazone Hydrochloride and Glimepiride combinations, especially concerning safety profiles, cardiovascular outcomes, and personalized therapy.

• Cardiovascular Safety Trials: The PROactive study, a landmark trial completed years ago, established pioglitazone's beneficial effects on macrovascular outcomes in certain populations but also highlighted risks like edema and heart failure. Current trials, such as PRIME (Preventing Renal and Cardiac Disease in Diabetes with Pioglitazone), focus on renal and cardiovascular endpoints among T2DM patients with high cardiovascular risk profiles.

• Combination Therapy Efficacy: Multiple phase III trials evaluate the efficacy and safety of fixed-dose combinations (FDCs) of Pioglitazone and Glimepiride than their monotherapy counterparts. These include assessments of glycemic control, weight gain, hypoglycemia incidence, and lipid profile impacts.

• Safety Profiles and Side Effect Management: A critical focus remains on mitigating adverse effects—particularly weight gain, edema, and osteoporosis risk from pioglitazone, and hypoglycemia risk from Glimepiride. Novel formulations and dosing strategies aim to optimize therapeutic windows.

• Innovative Delivery Systems: Research into sustained-release formulations, combination patches, and novel delivery mechanisms continues to explore improved patient adherence and reduced side effects.

Regulatory and Approval Landscape

• Global Approvals: Pioglitazone was approved by the FDA in 1999, but the market has seen restrictions due to safety concerns. The European Medicines Agency (EMA) withdrew pioglitazone’s marketing authorization in some EU countries over potential bladder cancer risks, though usage persists in others under strict regulations.

• Emerging Data and Labeling Changes: Recent studies incorporating real-world evidence have led regulatory agencies to update safety labels, emphasizing caution among patients with risk factors for heart failure or bladder cancer.

Research Gaps and Future Directions

• Personalized Medicine: Future trials are increasingly emphasizing pharmacogenomics to optimize patient-specific responses and minimize adverse effects.

• Long-Term Safety and Outcomes: There remains a need for expansive, long-term studies to balance the benefits of glycemic control with potential risks, particularly with regard to cancer and cardiovascular health.
