简要总结
This study is a prospective,multi-center, open-label, randomized controlled clinical trial,aims to assess the clinical noninferiority of 3 months (short-term) vs 12 months (long-term) of Dual Anti-Platelet Therapy (DAPT) in patients undergoing percutaneous coronary intervention implanted sirolimus target- eluting stent with abluminal grooves containing a biodegradable polymer (Firehawk™ stent). All participants met the inclusion criteria begin taking aspirin and open-label thienopyridine therapy before index procedure, and will be 1:1 randomized to 3 months or 12 month of DAPT at index procedure.
详细描述
This study will recruit 2,446 subjects with stable coronary artery disease in no more than 40 research centers in China. All participants met the inclusion criteria will be 1:1 randomized to 3 months or 12 month of DAPT after implanting Firehawk™ coronary stent.Clinical follow-up will be carried out at 30 days, 3 months, 6 months, 12 months, 18 months, 2 years and 3 years after index procedure.The primary study endpoint is Net Adverse Clinical and Cerebral Events (NACCE), a composite of all-cause death, myocardial infarction (MI), cerebral vascular accident (CVA) and major bleeding (academic research consortium [ARC] definition and GUSTO definition) at 18 months. Subjects that complete of 18 months follow-up will be regarded as having completed the primary endpoint. The secondary study endpoints contain ARC defined stent thrombosis (ST) at all study time-points; NACCE at 30 days,6,12,24 and 36 months of follow-up;major adverse cardiovascular events (MACE),major adverse cardiovascular and cerebral events (MACCE),target lesion revascularization (TLR),target lesion failure(TLF),ST at 30 days,6,12 ,18,24 and 36 months of follow-up; major bleeding at 1, 3, 6, 12 ,18,24 and 36 months of follow up; as well as cost-effective at 18 months of follow-up.

- •Subjects associated with drugs allergy (such as sirolimus, or structure-related compounds fluorinated polymers, thienopyridine or aspirin)
- •Subjects being suffered from other serious illness (such as cancer, congestive heart failure), which may cause drop in life expectancy to less than 18 months
