Detailed Description

A prospective, multicenter, single-arm clinical study. The study will be conducted in 3 to 5 investigational sites in the US and Canada and will enroll up to 60 participants. The population for this study is adult participants undergoing non-emergent percutaneous coronary intervention (PCI) as a stand-alone procedure or following non-emergent diagnostic angiography performed during the same procedure.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Male and Female subjects >18 years old.
  • Patients undergoing clinically indicated non-emergent PCI as a stand-alone procedure or in combination with diagnostic angiography during the same procedure.
  • Study target lesion characteristics: a) native de-novo coronary stenosis of at least 70% visually estimated stenosis, or at least 50% visually estimated stenosis and shown to be physiologically significant by flow-mediated criteria (FFR <0.80, IFR <0.91); b) estimated reference vessel diameter 2.0-4.5mm; c) lesion length <25mm; d) calcification not greater than mild.
  • Per investigator assessment, the patient may benefit from inflation distal perfusion during balloon inflation. Examples include, but are not limited to: (i) LV systolic dysfunction with LVEF<50% by any modality; (ii) a territory subtended by the target vessel downstream from the target lesion that is estimated to be in excess of 25% of viable LV mass; (iii) prior hemodynamic or electrical instablility during intervention on the target lesion; (iv) the potential to avoid placement of a coronary stent if a stent-like result can be achieved through prolonged balloon inflation.
  • Female subjects of childbearing potential must have a negative pregnancy test per standard of care for PCI and be practicing contraception.
  • Informed consent provided.

Exclusion Criteria:

  • Hemodynamic or arrhythmic instability within 48 hours or a myocardial infarction within 72 hours of PCI.
  • More than 2 lesions planned during index PCI.
  • Procedural complication developing prior to PCI of study target.
  • Ejection fraction (EF) <25%.
  • Creatinine clearance (Cr-Cl) <25 mg/dL.
  • Baseline flow at study target <TIMI-2.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Experimental
Adult subjects clinically indicated for non-emergent percutaneous coronary intervention (PCI) as a stand-alone procedure or following non-emergent diagnostic angiography performed during the same procedure that, in the physician's estimation, requires prolonged balloon inflation with distal perfusion.
Device: Ringer Perfusion Balloon Catheter
Non-emergent Percutaneous Coronary Intervention (PCI) for treatment of a coronary artery lesion with Ringer Perfusion Balloon Catheter.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Effectiveness of device success in dilatation/pre-dilatation of coronary stenosis during PCI.
Time Frame: During Procedure
Successful delivery, inflation, deflation and withdrawal of the Ringer device; final thrombolysis in myocardial infarction (TIMI) flow grade of 3 at the conclusion of the PCI procedure.
During Procedure
Rate of clinically relevant events
Time Frame: Discharge or 30 days, whichever comes first
Rate of Ringer related complications arising during delivery, inflation or removal of Ringer; freedom from major cardiac adverse events (MACE)
Discharge or 30 days, whichever comes first

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Successful PCI
Time Frame: During Procedure
Final residual stenosis ≤20% diameter stenosis (in-stent) or ≤50% diameter stenosis (stand-alone balloon) by visual angiographic estimation and freedom from MACE.
During Procedure
TIMI Flow
Time Frame: During Procedure
Maintenance of TIMI-2 or -3 flow into distal coronary bed during Ringer inflation
During Procedure
