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 2021-11-01; recorded start 2022-01-04
- 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
- Present: Participants are randomly assignedAllocation is recorded as randomised
- Present: Has a comparison groupThe record lists a placebo or comparator arm, or more than one study arm
- Present: Uses blinding (masking)A masking level is recorded in the record
- 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 6 other studies in this databaseCounted from the lead sponsor named in the record (Shockwave Medical, Inc.)
- Present: Sponsor has posted results for at least one studyBased on the sponsor’s studies in this database
- The record lists 1 condition.
- 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.
A strong methodological design for a study of this type, judged from its ClinicalTrials.gov record.

Shockwave Medical, Inc. has led 7 trials in our corpus
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
To demonstrate the safety and effectiveness of the Shockwave Reducer for treatment of patients with refractory angina pectoris treated with maximally tolerated guideline-directed medical therapy who demonstrate objective evidence of reversible myocardial ischemia in the distribution of the left coronary artery and who are deemed unsuitable for revascularization. A non-randomized single-arm registry will further assess the safety and effectiveness of the Shockwave Reducer in selected subjects with reversible myocardial ischemia in the distribution of the right coronary artery and who are deemed unsuitable for revascularization, subjects without documented obstructive coronary disease and abnormal coronary flow reserve (ANOCA), and subjects who cannot complete an exercise tolerance test due to lower limb amputation (above the ankle) or other physiologic condition with documented chronic mobility or balance issues that require the use of a walking aid.

Seattle Angina Questionnaire (SAQ) Score
Change in other Seattle Angina Questionnaire (SAQ) domain scores and clinical summary score at 6 months (primary endpoint), 12 month and annually post procedure compared to baseline. The Seattle Angina Questionnaire (SAQ) is a disease-specific questionnaire used to quantify patients' symptoms of angina and the extent to which their angina affects their functioning and quality of life. Possible scores range from 0 (daily angina) to 100 (no angina). Lower scores indicate worse angina symptoms.
