Clinical Trial Summary

Comparison of Angiography-derived Fractional FLow Reserve And IntraVascular Ultrasound-guided Intervention Strategy for Clinical OUtcomes in Patients with CoRonary Artery Disease

Description:

1. The primary hypothesis is that angiography-derived FFR-guided strategy for PCI with a drug-eluting stent (DES) will show non-inferiority in rates of patients-oriented composite outcomes (POCO) at 12 months after randomization, compared with IVUS-guided strategy for PCI with a DES in patients with coronary artery disease. 2. Study population and sample size calculation： Sample size calculation based on the event rates of previous trials, investigators predicted the rates of POCO at 12 months after PCI will be 7% in the Angiography-derived FFR-guided arm, and 8% in the IVUS-guided arm - Primary endpoint: patient-oriented composite outcome (a composite of all-cause death, MI, any revascularization) at 12 months after PCI - Design: non-inferiority, delta = 2.5% - Sampling ratio: angiography-derived FFR-guided strategy: IVUS-guided strategy = 1:1 - Type I error (α): One-sided 2.5% - Accrual time: 3 years - Total time: 4 years (accrual 3 years + follow-up 1 years) - Assumption: POCO 7.0% vs. 8.0% in angiography-derived FFR or IVUS-guided strategy, respectively - Statistical power (1- β): 80% - Primary statistical method: Kaplan-Meier survival analysis with log-rank test - Estimated attrition rate: total 5% - Stratification in Randomization: Presence of diabetes mellitus (35% of patients in each group) Based on the above assumption, we would need total 1,872 patients (936 patients in each group) with consideration of an attrition rate. 3. Research Materials and Indication for Revascularization： For the angiography-derived FFR-guided strategy arm, criteria for revascularization: angiography-derived FFR ≤ 0.80. For the IVUS-guided strategy arm, the criterion for revascularization is MLA ≤ 3mm2 or [3mm2 < MLA ≤ 4mm2 and plaque burden > 70%].
