Evaluating a new combination treatment for high blood pressure in elderly patients

An Open-Label, Superiority, Randomized, Comparative Study to Evaluate the Efficacy and Safety of Telmisartan, Amlodipine, and Chlorthalidone Fixed-Dose Combination Versus Telmisartan, Amlodipine, and Hydrochlorothiazide in Elderly Patients with Essential Hypertension Uncontrolled by Telmisartan and Amlodipine Combinations

Phase 4 Interventional Yuhan Corporation · NCT06041529

What this trial studies

This study aims to compare the efficacy and safety of a fixed-dose combination of Telmisartan, Amlodipine, and Chlorthalidone against a combination of Telmisartan, Amlodipine, and Hydrochlorothiazide in elderly patients suffering from essential hypertension that is not adequately controlled by the standard combination of Telmisartan and Amlodipine. It is a Phase IV, randomized, open-label, superiority study designed to determine which treatment provides better blood pressure control and safety for this demographic. Participants aged 65 and older with uncontrolled hypertension will be enrolled and monitored throughout the trial.

Who should consider this trial

Good fit: Ideal candidates for this study are elderly patients aged 65 and older with uncontrolled essential hypertension.

Not a fit: Patients with a history of drug allergies or hypersensitivity to the study medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for elderly patients with essential hypertension.

How similar studies have performed: Other studies have shown success with similar combination therapies for hypertension, indicating potential for positive outcomes in this trial.
