The CORE Platform Trial

Background: The leading cause of death worldwide is cardiovascular disease, with an estimated 19.8 million deaths per year. Coronary artery disease is a type of cardiovascular disease that can be treated with revascularisation interventions like coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI) and hybrid revascularisation (CABG and PCI). The COronary Revascularisation (CORE) Platform Trial is a multicentre, investigator-initiated, platform trial designed to evaluate several procedural and medical interventions for treatment of patients with coronary artery disease referred for coronary artery revascularisation. Methods: This Master Protocol describes the overarching design, organisation, and methodology of the CORE Platform Trial. The target population will be adults with coronary artery disease referred for coronary artery revascularisation. The platform will allow interventions to be assessed in parallel or sequentially across separate domains, each with predefined sample sizes, outcomes, and statistical analysis plans. The CORE Platform Trial is guided by three overarching principles: to promote and establish international collaboration; to conduct pragmatic trials that generate findings applicable to routine clinical practice while avoiding compromise to methodological rigor; and to avoid unnecessary complexity in methodology and statistical analyses. The HYCORE1 trial serves as the initial domain within the platform, with future domains including colchicine; sodium-glucose co-transporter 2 inhibitor; and hybrid versus PCI revascularisation. Randomisation will be web-based with allocation concealment, stratification by site and domain, and blinding where feasible. Discussion: The CORE Platform Trial provides a collaborative, pragmatic, and methodologically rigorous framework for evaluating interventions in patients with coronary artery disease referred for coronary artery revascularisation. By using shared infrastructure and predefined domain-specific protocols, the platform aims to improve efficiency, reduce research waste, and strengthen the evidence base for coronary artery disease care.

Inclusion Criteria: The CORE Platform Trial will include adults (greater or equal to 18 years of age) with coronary artery disease who are referred for coronary artery revascularization of any type. Separate inclusion criteria will be defined for each randomised comparison in the platform. Exclusion Criteria: Separate exclusion criteria will be defined for each randomised comparison in the platform.
