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 Landscape

Current Clinical Trials and Developments

Both Glimepiride and Pioglitazone Hydrochloride are part of extensive clinical evaluations focusing on safety, efficacy, and their roles in combination therapies.

Glimepiride:
As a third-generation sulfonylurea, Glimepiride’s clinical trials predominantly investigate its long-term safety profile, especially concerning hypoglycemia risk and cardiovascular outcomes. Notably, recent studies examine its use in specific populations, such as elderly patients and those with comorbidities. The ongoing trials aim to position Glimepiride within combination regimens that reduce adverse events.

Pioglitazone Hydrochloride:
Despite past controversies relating to bladder cancer risk, Pioglitazone continues to be actively evaluated. Recent clinical trials focus on its cardiovascular benefits, effects on insulin sensitivity, and potential neuroprotective properties. Notably, trials such as the "PROactive" study and subsequent observational studies reinforce its role, although regulatory restrictions in certain markets remain.

Regulatory Status and Ongoing Evaluations

• FDA Position:
  The U.S. Food and Drug Administration (FDA) has maintained warnings regarding Pioglitazone's bladder cancer risk, leading to cautious prescribing. Conversely, Glimepiride remains widely approved but subject to REMS (Risk Evaluation and Mitigation Strategies).

• EMA and Global Approvals:
  The European Medicines Agency (EMA) downscaled concerns over Pioglitazone but emphasizes careful patient selection. Both drugs are under continuous review support their ongoing clinical use.

Emerging Clinical Trials

Emerging research explores combination therapies integrating Glimepiride or Pioglitazone with novel agents such as SGLT2 inhibitors and GLP-1 receptor agonists. These trials aim to optimize glycemic control and reduce adverse event profiles.
