Trial Outcomes & Findings for Hybrid Coronary Revascularization Trial (NCT NCT03089398)

NCT ID: NCT03089398

Last Updated: 2025-05-23

Results Overview

The current sample size of 200 patients will not provide sufficient power to test the original null hypothesis of the trial. However, it will allow for an estimate of the MACCE rate in the two groups. A 2-year follow-up will be used to capture and understand the difference in MACCE between the two procedures. This reasoning is based on the NHLBI-funded Hybrid Revascularization Observational Study (ClinicalTrials.gov Identifier NCT01121263), which enrolled 200 HCR and 98 multi-vessel PCI with drug-eluting stent (DES) patients, and demonstrated similar risk-adjusted MACCE rates over the first 12 months following the intervention but divergence by approximately 18 months of followup. Therefore, it is important to continue the follow-up of the 200 randomized patients to at least 24 months. Of note, some patients who were enrolled early in the trial will have up to 3 years of follow-up data collected by the time the final patient randomized completes the 2-year time point.

Hybrid Coronary Revascularization Group
Hybrid Coronary Revascularization (HCR) is defined, for the purposes of this trial, as a planned off-pump minimally invasive (sternal-sparing), isolated LIMA-LAD revascularization, combined with percutaneous revascularization of at least one non-LAD target. Hybrid Coronary Revascularization (isolated LIMA-LAD): sternal-sparing, off-pump, isolated LIMA-LAD revascularization Hybrid Coronary Revascularization (PCI): percutaneous revascularization of at least one non-LAD target
Percutaneous Coronary Intervention
PCI will be performed using standard techniques at the discretion of the operator. Only Food and Drug Administration (FDA) and Health Canada approved commercially available metallic drug-eluting stents may be used in this protocol. Percutaneous Coronary Intervention: Multi-vessel PCI with metallic drug-eluting stents (DES) including the LAD and or LM. Only FDA approved commercially available metallic drug-eluting stents may be used in this protocol.

The current sample size of 200 patients will not provide sufficient power to test the original null hypothesis of the trial. However, it will allow for an estimate of the MACCE rate in the two groups. A 2-year follow-up will be used to capture and understand the difference in MACCE between the two procedures. This reasoning is based on the NHLBI-funded Hybrid Revascularization Observational Study (ClinicalTrials.gov Identifier NCT01121263), which enrolled 200 HCR and 98 multi-vessel PCI with drug-eluting stent (DES) patients, and demonstrated similar risk-adjusted MACCE rates over the first 12 months following the intervention but divergence by approximately 18 months of followup. Therefore, it is important to continue the follow-up of the 200 randomized patients to at least 24 months. Of note, some patients who were enrolled early in the trial will have up to 3 years of follow-up data collected by the time the final patient randomized completes the 2-year time point.

Population: The overall analysis population represents the number of patients who contributed to at least one of the pre/post measurements. Patients randomized to the HCR arm and received PCI only OR patients randomized to the PCI arm and received CABG are not included. Most patients switched interventions due to their preference. Patients who did not receive any procedures are also excluded. Patients received no interventions due to physician decision or early termination (withdrawal or lost to follow-up).

For HCR patients, medications are prior/during/after CABG. For PCI patients, medications are prior/during/after the last PCI. Number of participants requiring medications at any time 24 Hours Prior to, During, and Within 24 Hours of the Procedure. Procedures can occur up to 90 days after randomization.

SECONDARY outcome

Timeframe: Up to 24 months

Population: While quality of life data was collected, they are not usable in a cost-effectiveness analysis due to the reduced sample size and reduced follow-up. In addition, since the trial was halted prematurely, cost data was not collected. Therefore, a cost-effectiveness analysis is not feasible.

Health Status as measured by cost-effectiveness. Cost-effectiveness will be evaluated using a micro-simulation model, which will predict the accrued health care costs and quality-adjusted life expectancy for each subject at the end of the trial follow-up period and in addition over a lifetime horizon.

SECONDARY outcome

Timeframe: Up to 24 months

Population: HCR: Obtaining data from the STS registry was not straightforward and was related to difficulty in obtaining the data and linking all clinical trial patients with their STS data. In general, more work needs to be done before registry data can be incorporated into clinical trials. PCI: Researchers were unable to obtain data from CATH-PCI registry. At the time of trial start-up, the registry was being restructured and moved to a different platform. Linkage to clinical trial data was not possible.

For the HCR group, partial data will be extracted and transferred from the STS registry. Thus, this study will also allow evaluation of the process of data transfer, assessment of the data quality, and eventually determination of the feasibility to conduct a clinical trial with data linked to a registry.
