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.

  • Present: Registered before enrolment beganFirst posted 2019-11-06; recorded start 2020-11-12
  • Present: Has a defined primary outcomeA primary outcome measure is listed in the record
  • Present: The primary outcome states a time frameThe primary outcome measure records a time frame
  • Not stated: Participants are not randomly assignedAllocation is recorded as non-randomised
  • Present: Has a comparison groupThe record lists a placebo or comparator arm, or more than one study arm
  • Not stated: Open label (no blinding)Masking is recorded as none (open label)
  • Not stated: An ethics committee is not stated in the registry recordThis registry's ingested record has no ethics-committee field
  • Not stated: Regulatory oversight (such as an IND or IDE) is not stated in the registry recordThis registry's ingested record has no regulatory-authorisation field
  • Not stated: A data monitoring committee is not stated in the registry recordThis registry's ingested record has no data-monitoring-committee fieldA data monitoring committee is not required for many smaller studies, and its absence here is not unusual.
  • Present: No cost to participants is mentioned in the recordChecked the summary, description and eligibility text; no cost-to-participant phrase found
  • Present: Sponsor has 47 other studies in this databaseCounted from the lead sponsor named in the record (Edwards Lifesciences)
  • Present: Sponsor has posted results for at least one studyBased on the sponsor’s studies in this database
  • The record lists 2 conditions.
  • Lead sponsor type recorded as: industry.

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 rigourMODERATE

A moderately rigorous 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.

תקציר

This study will establish the safety and effectiveness of the SAPIEN M3 System in subjects with symptomatic, at least 3+ mitral regurgitation (MR) for whom commercially available surgical or transcatheter treatment options are deemed unsuitable. Following completion of enrollment, subjects will be eligible for enrollment in the continued access phase of the trial.

This is a prospective single-arm, multicenter study.

  2. מדד תוצאה משני

    Improvement in NYHA functional class compared to baseline

    New York Heart Association (NYHA) functional classification of heart failure is based on how much a patient is limited during physical activity. The rating ranges from I-IV. I = no limitations of physical activity; II = slight limitations of physical activity, ordinary physical activity results in fatigue, palpitation, shortness of breath; III = marked limitations of physical activity, less than ordinary activity causes fatigue, palpitation, or shortness of breath; IV = unable to carry on any physical activity without discomfort, symptoms of heart failure at rest.

  3. מדד תוצאה משני

    Improvement in KCCQ Overall Score compared to baseline

    The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. An overall summary score can be derived from the physical function, symptom (frequency and severity), social function and quality of life domains. Scores are transformed to a range of 0-100, in which higher scores reflect better health status.
