Brief Summary:
This is a prospective, multicenter, randomized controlled clinical trial, which plans to enroll 260 subjects.

Condition or disease Intervention/treatment Phase
Coronary Artery Disease In Stent Restenosis Device: drug-coated balloon Catheter Not Applicable

Detailed Description:

This is a prospective, multicenter, randomized (1:1) controlled clinical trial, which plans to enroll 260 subjects. The aim of study is to assess the safety and efficacy of SeQuent® SCB in the treatment of in-stent restenosis in coronary arteries.

All eligible subjects with ISR lesion in coronary will be randomly assigned to receive SeQuent® SCB (study group) or receive SeQuent® Please Neo (control group) balloon treatment. All subjects will be scheduled to clinical follow up at 30 days, 6 months, 9 months and 12 months after index procedure and will be scheduled to receive the angiography at 9 months after index procedure. The primary endpoint was segment late luminal loss at 9 months after index procedure.

Primary Outcome Measures :
  1. In-segment late loss [ Time Frame: at 9 months after index procedure ]
    In-segment late loss(LLL) is defined as the difference between the MLD immediately after the procedure and the MLD at 9-month follow-up angiography after index procedure. MLDs are measured by QCA.


Secondary Outcome Measures :
  1. The success rate of intervention treatment [ Time Frame: 1-3 days ]
    including device success, lesion success and clinical success

  2. Binary restenosis rate of target lesion [ Time Frame: 9 months after index procedure ]
    A diameter stenosis of > 50% at the previously treated lesion site, including the originally treated site plus the adjacent vascular segments 5 mm , proximal and 5 mm distal to the site . Percent diameter stenosis was defined as [1(MLD/reference vessel diameter)]100.

  3. Target lesion failure (TLF) rate [ Time Frame: 30 days, 6 months, 9 moths, 12 months after index procedure ]
    The composite of ischemia-driven revascularization of the target lesion, MI related to the target vessel, or cardiac death related to the target vessel

  4. PoCE [ Time Frame: 30 days, 6 months, 9 moths, 12 months after index procedure ]
    a composite of all death, MI and any revascularization

  5. ARC-defined stent thrombosis [ Time Frame: 30 days, 6 months, 9 moths, 12 months after index procedure ]
    timing (acute, subacute, late and very late stent thrombosis); relationship (definite, probable and possible stent thrombosis)
