Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults aged 18 to under 85 with stable angina or a stabilised acute coronary syndrome who can have a planned stent procedure (PCI).

Age
At least 18 years and younger than 85 years.
Sex
All sexes can join.
Disease stage
Stable angina, or acute coronary syndrome affecting only vessels other than the one that caused the event, outside the main procedure during an acute STEMI.
Earlier treatment
No chest or coronary artery radiotherapy before or planned. Not currently in another drug or device study.

Main reasons for not taking part

  • STEMI as the way the illness first showed itself
  • A chronic total occlusion as the target vessel
  • Severe kidney problems (eGFR 30 mL/min/1.73 m2 or lower)
  • Planned major surgery within 24 months
  • Pregnancy or nursing

The registry criteria, word for word

Show all 24 criteriaShow less

Who can take part

  • The subject must be at least 18 years of age and younger than 85 years old
  • Eligible for elective PCI
  • Stable angina or ACS (non-culprit vessels only and outside of primary intervention during acute STEMI)
  • Subject willing to participate and able to understand, read and sign the Informed Consent

Who cannot take part

  • Inability to take DAPT (both aspirin and a P2Y12 inhibitor) for at least 12 months in the patient presenting with an ACS, or at least six months in the patient presenting with stable CAD, unless the patient is also taking chronic oral anticoagulation in which case a shorter duration of DAPT may be prescribed per local standard of care
  • The subject has received a functioning solid organ transplant or is active on a waiting list for any solid organ transplants with expected transplantation within 24 months
  • The subject has previously received or is scheduled to receive radiotherapy to a coronary artery (vascular brachytherapy) or the chest/mediastinum
  • The subject has a history of bleeding diathesis or coagulopathy or has had a significant gastro-intestinal or significant urinary bleed within the past six months. The subject has had a cerebrovascular accident or transient ischemic neurological attack (TIA) within the past six months, any prior intracranial bleed, any permanent neurologic defect, or any known intracranial pathology (e.g., aneurysm, arteriovenous malformation, etc. The subject has a life expectancy of <2 years for any non-cardiac cause
  • The subject is currently participating in another investigational drug or device clinical study
  • Significant contraindication to adenosine administration (e.g. heart block, severe asthma)
  • Severe valvular disease
  • Planned major cardiac or non-cardiac surgery within 24 months after the index procedure. Note: major surgery is any invasive procedure in which an extensive resection is performed, e.g., a body cavity is entered, organs are removed, or normal anatomy is altered. Note: minor surgery is an operation on the superficial structures of the body or a manipulative procedure that does not involve a serious risk. Planned minor surgery is not excluded
  • Subject has known hypersensitivity or contraindication to any of the study drugs (including all P2Y12 inhibitors, one or more components of the study devices, including everolimus, zotarolimus, biolimus, sirolimus, cobalt, chromium, nickel, platinum, tungsten, acrylic, and fluoropolymers, or radiocontrast dye that cannot be adequately pre- medicated
  • The subject receives immunosuppressant therapy or has known immunosuppressive or severe autoimmune disease that requires chronic immunosuppressive therapy (e.g., human immunodeficiency virus, systemic lupus erythematosus, etc.). Note: corticosteroids are not included as immunosuppressant therapy
  • The subject has a documented or suspected hepatic disorder defined as cirrhosis or Child-Pugh ≥ Class B
  • Presence of other anatomic or comorbid conditions or other medical, social, or psychological conditions that, in the investigator's opinion, could limit the subject's ability to participate in the clinical investigation or to comply with follow-up requirements or impact the scientific soundness of the clinical investigation results
  • Severe renal dysfunction defined as an eGFR ≤30 mL/min/1.73 m2
  • Subject has a platelet count <100,000 cells/mm3 or >700,000 cells/mm3
  • Comorbidity with life expectancy ≤ 2 years
  • STEMI as clinical presentation
  • Chronic total occlusion as a target vessel
  • Uncontrolled or recurrent ventricular tachycardia
  • Hemodynamic instability
  • Pregnancy or nursing

About the trial

What the trial wants to find out

Recently, a new device for measuring physiological lesion severity, the pressure microcatheter, was introduced. The pressure microcatheter provides similar information to the conventional measurement technique but differs as it is easily advanced on a customary coronary wire and simplifies pullback maneuvers. The pressure microcatheter has been shown to provide comparable FFR results to pressure wires.

Insightful-FFR is an investigator-driven, multicenter, randomized, open-label and prospective trial of patients with stable coronary artery disease or stabilised non-ST elevation acute coronary syndrome (ACS) with epicardial stenosis considered for PCI aiming at comparing clinical outcomes between pressure microcatheter and pressure wire-guided strategies. The study hypothesis states that the use of a Pressure Microcatheter for clinical decision making would be non-inferior to pressure wire-based strategy

After determining the presence of a coronary artery disease/ stabilized acute coronary syndrome, patients will be randomized to use a pressure microcatheter (investigational device) or a pressure wire (comparator) to guide and optimize percutaneous coronary intervention (PCI). Patients will be followed up in hospital at 12 months and yearly until five years.

The 4 groups in the trial

  • Pressure Microcatheter guided strategy - PIOS-MCTreatment being tested

    Patients will be treated with the Pressure Microcatheter during PCI. After completing an angiographically successful PCI, patients will be randomized to FFR-guided stent optimization (PIOS).

  • Pressure Wire guided strategy - PIOS-PWExisting treatment, for comparison

    Patients will be treated with the Pressure Wire during PCI. After completing an angiographically successful PCI, patients will be randomized to FFR-guided stent optimization (PIOS).

  • Pressure Microcatheter guided strategy - Standard of careTreatment being tested

    Patients will be treated with the Pressure Microcatheter during PCI. After completing an angiographically successful PCI, patients will receive the standard of care treatment.

  • Pressure Wire guided strategy - Standard of careExisting treatment, for comparison

    Patients will be treated with the Pressure Wire during PCI. After completing an angiographically successful PCI, patients will receive the standard of care treatment.
