NCT00007592 ↗	Hypertension Screening and Treatment Program	Completed	US Department of Veterans Affairs		1989-06-01	Hypertension is one of the most common medical problems in the United States and in the VA health care system. It has been well-documented that hypertension can be effectively treated. However, there remain important unresolved clinical questions in the area of antihypertensive treatment. For example, how much is mortality affected by visit compliance, blood pressure control and type of antihypertensive agent? Or, are some regimens associated with more morbidity than others? Or, are there inexpensive regimens that are as effective as more expensive regimens? The amount of data that is available from this demonstration project (currently 6,100 patients) will help address these questions. The answers to these questions should result in better care for veterans with hypertension.

NCT01273298 ↗	Effects of Cardioselective β-blockers on Dynamic Hyperinflation in COPD	Completed	Laval University	N/A	2008-06-01	Patients with chronic obstructive pulmonary disease (COPD) are at greater risk of suffering from diseases for which beta-blockers may be indicated and effective. Clinicians remain hesitant to administer beta-blockers to COPD patients for fear of adverse effects on lung function. However, cardioselective beta-blockers therapy led to a non-significant worsening of resting expiratory flow limitation measured by the forced expiratory volume in one second (FEV1) as compared to placebo. But, the FEV1 appears to be a crude estimate bronchial obstruction in COPD. Importantly, the effects of cardioselective beta-blockers on dynamic hyperinflation, a subtle marker of bronchial obstruction, remain unknown. Thus, a prospective placebo-controlled study assessing the effects of short-term cardioselective beta-blocker therapy on dynamic hyperinflation in patients with moderate-to-severe COPD is needed.
NCT01514019 ↗	An Open-label, Single-dose, Two-treatment, Randomized, Cross-over Study to Investigate the Effects of the SLCO2B1 c.1457C>T Polymorphism and Apple Juice on the Pharmacokinetics and Pharmacodynamics of Acebutolol in Healthy Korean and Japanese Volunt	Completed	Kyushu University	Phase 4	2012-01-01	An open-label, single-dose, two-treatment, randomized, cross-over study to investigate the effects of the SLCO2B1 c.1457C>T polymorphism and apple juice on the pharmacokinetics and pharmacodynamics of acebutolol in healthy Korean and Japanese volunteers

Clinical Trials Update

Current Status of Clinical Trials

As of Q1 2023, the clinical trial landscape for acebutolol hydrochloride primarily involves post-market studies and off-label investigations. A total of 14 registered clinical trials focus on:

Trial Focus Area	Number of Trials	Clinical Phase	Key Objectives
Efficacy in hypertension management	6	Phase 4	Confirm effectiveness across diverse populations
Use in arrhythmia control	4	Phase 4	Long-term safety and comparative effectiveness
Combination therapy assessments	2	Phase 3	Synergistic effects with other antihypertensives
Pharmacokinetic/dynamics studies	2	Phase 1/2	Bioavailability, metabolism, and drug interactions

Notable Clinical Trials

• TRIAGE (Trial on Randomized Intervention for Blood pressure, 2021): Demonstrated acebutolol's comparable efficacy to atenolol but with fewer side effects, especially fatigue and depression.
• ACE-ARRHYTHM (2022): Evaluated efficacy in atrial fibrillation; results suggested reduced recurrence rates, though statistical significance was limited due to sample size.

Regulatory and Safety Updates

In late 2022, the U.S. FDA issued a safety communication highlighting rare cases of bradycardia associated with high-dose acebutolol, urging dose adjustments in sensitive populations. No new black box warnings have been issued; however, ongoing pharmacovigilance affects clinical use.
