NCT05437900

Brief Summary

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.

  • 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.

  • 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 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 previously received or is scheduled to receive radiotherapy to a coronary artery (vascular brachytherapy) or the chest/mediastinum.

Model Details: Patients with one or more coronary stenoses will be randomized to either pressure microcatheter or pressure wire-based strategies for clinical decision making. Clinical decision making for PCI could be based either on FFR or NHPR. FFR or NHPR will support clinical decisions to defer or treat at the operator discretion. In cases with a positive FFR (≤ 0.80) or NHPR (≤0.89), patients will undergo a hyperemic FFR pullback to guide the PCI procedure further. PCI will be performed using last-generation drug-eluting stents (DES) at operator's discretion. After completing an angiographically successful PCI, patients will be randomized to FFR-guided stent optimization (PIOS) or standard of care (SOC). The one-step randomization process in four groups permits an uninterrupted invasive procedure avoiding the logistic issues related to a second randomization during the invasive procedure while preserving the statistical power and balance between groups.
