About this study
Aim: to compare the treatment effects of Bisoprolol (beta 1 receptor specific beta blocker (BB)) and Verapamil (cardio-specific calcium channel blockers (CCB)) in patients with non-obstructive hypertrophic cardiomyopathy (HCM).
Background: Hypertrophic cardiomyopathy (HCM) is characterized by hypertrophy of the left ventricular wall and a hypercontracted state of the sarcomeres. This narrows the left ventricular cavity, but though the left ejection fraction is increased the stroke volume and the cardiac output cannot be fully compensated. The disease manifestations can be mild or develop into severe functional limitations and devastating complications at early age. Dyspnea, chest pain, palpitations and syncope are the most common symptoms, and patients are at risk of supraventricular and ventricular arrhythmias. Arrhythmias and sudden cardiac deaths may precede heart failure symptoms. Patients with symptomatic HCM are treated initially with beta blockers and calcium channel blockers. However, there is limited evidence supporting the effectiveness of this guideline-recommended treatment in HCM.

Methods: The study is a multicenter, double-blinded, randomized, placebo-controlled cross-over trial. Patients are randomized in to three 35-days treatment periods with Bisoprolol, Verapamil and Placebo. Each treatment period includes a 7-days up titration period, a 21-days target dose period and a 7-days down titration period. Between treatment periods 45 days treatment pause is allowed. End point will be evaluated at day 21 (- 4 days). Patients will be evaluated by cardiopulmonary exercise test, echocardiography, 7 day Holter-monitoring, biomarkers and the Kansas City Cardiomyopathy Questionnaire (KCCQ). A subgroup of patients will also be evaluated with cardiac magnetic resonance imaging.
Hypotheses: Three separate phases each with one primary effect parameters will be analyzed between treatment with Bisoprolol and Verapamil:
Phase 1: The maximal oxygen consumption (VO2 max) is different (ΔVO2 max ≥1 ml/kg/min) between treatments in non-obstructive HCM patients Phase 2: The left ventricular enddiastolic volume (LVvol) is different (ΔLVvol ≥3 ml) between treatments in non-obstructive HCM patients.
Phase 3: The incidence of non-sustained ventricular tachycardia (NSVT) is different (Hazard ratio ≥ 0.5) between treatments in non-obstructive HCM patients.
The trial will be performed and analyzed in three phases, and each phase may be unblinded and analyzed separately.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Aim: to compare the treatment effects of Bisoprolol (beta 1 receptor specific beta blocker (BB)) and Verapamil (cardio-specific calcium channel blockers (CCB)) in patients with non-obstructive hypertrophic cardiomyopathy (HCM).

Arrhythmias and sudden cardiac deaths may precede heart failure symptoms. Patients with symptomatic HCM are treated initially with beta blockers and calcium channel blockers. However, there is limited evidence supporting the effectiveness of this guideline-recommended treatment in HCM.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Verapamil and Bisoprolol in people with Non-obstructive Hypertrophic Cardiomyopathy, run by Morten Steen Kvistholm Jensen at 4 sites in Denmark.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 20 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Morten SK Jensen (004540145482, morten.jensen@rm.dk), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Maximal oxygen consumption (VO2 max) (time frame: Changes will be evaluated at day 21 in each treatment arm). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Mar 2025.
