How this study is set up

The points below are drawn from the public registry record for this study. Each one cites the field or sentence it came from. A dash (—) means the record does not state something — not that it is missing or wrong. Many well-run studies, especially small ones, leave some of these blank.

  • Intervention regulatory context: investigational, within a phased regulatory pathway.

Trial stature

Three independent measures of this study, described from its registry record — not a recommendation about it. A rigorous study by investigators nobody has heard of is better evidence than a weak study led by a famous one. How these are scored.

Investigator standingUNKNOWN

We have no verifiable track record for the investigator named on this trial. That is common for early-career investigators and for records held outside ClinicalTrials.gov — it is not a negative signal.

How this score is built
  • Investigator standing0/100

    No investigator recorded in the registry for this trial

These describe the registry record only, and today we hold ClinicalTrials.gov data. Absent fields lower a score, and absence often reflects registration practice rather than study quality. A high-stature trial is not necessarily safer or a better choice for you — enrolling in a large definitive trial can mean a higher chance of receiving placebo, while a small early-phase study may be the only route to a new therapy.

Summary

The purpose of this extension study is to collect additional safety and efficacy on QCZ484 for hypertensive patients who successfully completed the parent study, CQCZ484A12201 or additional QCZ484 studies as specified in the respective parent study protocols.

This is a single arm, multicenter, OLE study designed to evaluate long-term safety, tolerability and efficacy of QCZ484, administered SC, once Q6M, in patients with HTN, who have successfully completed treatment period in the parent studies of the QCZ484 HTN program. Participants at sites from the parent study will be offered the option to enroll in this extension study at the Month 12 visit upon successful completion of the parent study treatment.

Eligibility as written in the registry

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. 3. No significant safety issue that may place participant at safety risk as determined by the Investigator. 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. Other protocol-defined inclusion/exclusion criteria may apply
