Is this trial a fit for you?

Likely a good fit

Adults with hypertension who completed a QCZ484 parent study and have no safety concerns preventing long-term therapy.

Probably not a fit

Patients with significant liver disease, certain cardiac arrhythmias, persistent atrial fibrillation, or new significant valvular disease may not benefit and could be excluded.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a single-arm, multicenter extension assessing QCZ484 safety, tolerability, and efficacy over long term in hypertensive patients who completed prior QCZ484 studies. Participants receive QCZ484 subcutaneously every six months. The study collects ongoing safety data and evaluates whether blood pressure control is maintained or improved in the extension setting. Enrollment is offered to eligible participants who completed the parent study, with continued monitoring at ongoing study visits.

Why it matters

Potential benefit: If successful, participants may maintain BP control with QCZ484 and experience continued safety monitoring.

How similar studies have gone: Open-label extensions are commonly used to assess long-term safety and tolerability of therapies after initial trials; results have been favorable for several biologic agents in HTN programs, though each agent is unique.

Inclusion Criteria:

1. Signed informed consent must be obtained prior to participation in the study.
2. Successful completion of treatment period on QCZ484 study medication in parent study.

Exclusion Criteria:

Participants meeting any of the following criteria, may it be pre-existing or developed during the parent study, are not eligible for inclusion in this study:

1. Evidence of hepatic disease that would put participant at risk by taking QCZ484 for long term as determined by the Investigator.
2. Clinically significant cardiac arrhythmias (e.g., ventricular tachycardia), high-grade atrioventricular (AV) block (e.g., Mobitz type II and third-degree AV block in absence of a pacemaker) developed during the parent study.
3. Permanent or persistent atrial fibrillation developed during the parent study.
4. Clinically significant valvular heart disease developed during the parent study.
5. Acute myocardial infarction (AMI) or unstable angina, or any percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) developed during the parent study. Any history of ischemic or hemorrhagic stroke or transient ischemic attack any time prior to enrollment.
