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.

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.

Methodological rigourDEFINITIVE

A definitive-grade design for a study of this type, judged from its ClinicalTrials.gov record.

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

A prospective, multinational, randomized, double-blind, clinical trial evaluating the safety and effectiveness of a novel atrioventricular interval modulation (AVIM) algorithm downloaded into a dual-chamber Medtronic Astra/Azure pacemaker.

The study will be conducted in three phases: 1) Screening Phase, 2) Double-blind Randomized Phase (1 year), and 3) Unblinded Phase (2 years). Patients scheduled for implantation of an Astra/Azure pacemaker, or those who already have one implanted, who also have hypertension, may be screened for inclusion into this study. Subjects meeting randomization eligibility criteria will have the investigational AVIM Therapy RAMware downloaded into the Astra/Azure pacemaker and be randomized 1:1 to either have AVIM therapy turned ON or turned OFF. All subjects will continue to receive antihypertensive drug therapy.
