Clinical Trial Summary

PIONEER-II OPC trial is a prospective, multicenter, single-arm registry trial. 1000 subjects from approximately 40 interventional cardiology centers will be enrolled to evaluate the target lesion failure(TLF) as the primary endpoint at 1 year. And all the subjects will be followed up to 5 years to attain the data of the secondary endpoints.

Description:

Realizing even more uniform and complete endothelial coverage, BuMA Supreme™ biodegradable drug coating coronary stent system comprises a new generation of biodegradable drug eluting stent under development by Sino medical science(SINOMED). BuMA Supreme™ reconfigures BuMA™ DES utilizing a high caliber cobalt chromium platform coated with rapidly degrading PLGA scaffold.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Target Lesion Failure	Target Lesion Failure(TLF) is defined as cardiac death, target vessel myocardial infarction(MI), or clinically-driven target lesion revascularization (TLR).	1 year
Secondary	Stent implantation success rate	The stent implantation success rate includes device, lesion and clinical success rate.	5 years after PCI
Secondary	Device-oriented Composite Endpoint(DoCE)	Device-oriented Composite Endpoint is defined as cardiac death, target vessel MI, or clinically-driven TLR (TLF).	1, 6, 12 month, and annually up to 5 years post procedure
Secondary	Patient-oriented Composite Endpoint (PoCE)	Patient-oriented Composite Endpoint is defined as all cause death, all MI, or any revascularization.	1, 6, 12 month, and annually up to 5 years post procedure
Secondary	Academic Research Consortium(ARC) defined stent thrombosis	Definite and probable stent thrombosis during acute, subacute, later and very late phase.	5 years after PCI
