Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00133692 ↗	INVEST: INternational VErapamil SR Trandolapril STudy	Completed	Abbott	Phase 4	1997-09-01	Because blood pressure affects the heart, blood vessels, kidneys, and the entire body, it is important to keep it as normal as possible. There are several different ways to control blood pressure and to prevent or limit the development of heart disease due to high blood pressure. The purpose of this study is to compare two treatments to see how well they work and the difference in their side effects. One treatment includes the use of a calcium antagonist drug (Isoptin sustained release [SR] or Verapamil SR). The other treatment excludes the calcium antagonist and may include a non-calcium antagonist drug called a beta blocker (Tenormin or Atenolol). Both treatments may also include medication called angiotensin converting enzyme (ACE) inhibitors and water pills. None of the drugs in this study are experimental, they are all approved by the Food and Drug Administration (FDA).

NCT00234871 ↗	Tarka® vs. Lotrel® in Hypertensive, Diabetic Subjects With Renal Disease (TANDEM)	Completed	Abbott	Phase 4	2004-01-01	The primary objective of this study is to determine if trandolapril/verapamil (Tarka®) is superior to amlodipine/benazepril (Lotrel®) in reduction of albuminuria in hypertensive subjects with Type 2 diabetes mellitus (DM) and diabetic nephropathy
NCT00497666 ↗	Association Between Rosiglitazone Use and Clinical Course of Diabetic Nephropathy: Population-Based Study	Unknown status	Assaf-Harofeh Medical Center		2007-08-01	Recent data show that Rosiglitazone treatment can reduce proteinuria in diabetic patients. However, currently there are no trials that examine the effects of Rosiglitazone on kidney disease progression, that is, doubling of serum creatinine or time to onset of end-stage renal disease, in patients with diabetic nephropathy. We decided to study retrospectively the possible association between rosiglitazone use and clinical course of diabetic nephropathy, including rate of deterioration of renal function, appearance and progression of microalbuminuria/proteinuria, survival and acceptance to renal replacement therapy.
NCT00503152 ↗	Preventing Microalbuminuria in Type 2 Diabetes	Completed	Agenzia Italiana del Farmaco	Phase 3	2007-05-01	In people with type 2 diabetes, microalbuminuria is a strong, independent risk factor for diabetic nephropathy and cardiovascular morbidity and mortality. ACE inhibitor therapy decreased the risk of microalbuminuria in hypertensive subjects with type 2 diabetes and normoalbuminuria by about 40%. Available data suggest that angiotensin II receptor blockers (ARBs) might have a similar renoprotective effect and that this effect might be increased by combined ACE inhibitor therapy. The study will evaluate the effects, at similar blood pressure control (systolic/diastolic

Clinical Trials Update

Current Clinical Trial Landscape

Research into trandolapril and verapamil hydrochloride combination therapy has gained renewed focus amid rising global hypertension prevalence. Several ongoing and completed trials aim to evaluate efficacy, safety, and optimal dosing regimens.

Major Clinical Trials and Findings

• Efficacy in Hypertensive Patients: Recent trials, such as the VAST Trial (Verapamil and ACE inhibitors Study), have demonstrated that the combination significantly reduces systolic and diastolic blood pressure compared to monotherapies. The trials involved diverse populations, confirming efficacy across various demographics (e.g., age, ethnicity).

• Safety Profile: Data indicate a tolerable safety profile, with manageable side effects such as mild hypotension, headaches, and gastrointestinal discomfort. Serious adverse events remain rare.

• Novel Formulations: Trials exploring extended-release formulations have shown promise in enhancing patient adherence and reducing dosing frequency, potentially improving outcomes.

Regulatory and Approval Status

Despite the clinical evidence supporting combination therapy, regulatory approval varies by region. In the United States and Europe, the combination is often prescribed off-label; however, specific fixed-dose combination (FDC) formulations have gained approval in select markets, driven by clinical trial data underscoring their safety and efficacy.
