Clinical Trial Summary

A Prospective, Multicenter, Randomized, Two-Arm, Single-blind Superiority Trial to Evaluate the Safety and Efficacy of the MagicTouch™ Sirolimus- Coated Balloon in the Treatment of Coronary Drug-Eluting Stent In-Stent Restenosis. Subjects with prior DES implantation presenting with ISR lesions undergoing PCI will be randomized into two groups: treatment with the MagicTouch™ sirolimus-coated balloon or POBA on a 2:1 basis. Approximately 492 subjects will be enrolled in the randomized study in a maximum of 50 study sites located in the United States. The goal is to establish the safety and efficacy of the MagicTouch™ sirolimus- coated balloon in treatment of coronary in-stent restenosis (ISR).

Description:

All subjects providing informed consent will have their medical history reviewed and will undergo a physical examination, laboratory screen, and a standardized 12-lead ECG within 7 days of procedure. Women of childbearing potential will have a pregnancy test within one week prior to the procedure. If subjects meet the inclusion and exclusion criteria of the study, they will be randomized to one of two treatment groups, and will then undergo treatment with MagicTouch™ sirolimus-coated balloon or POBA of the target ISR lesion, per trial protocol. One pre-procedure and all post-procedure biomarker blood draws will be sent to a central core laboratory for analysis of troponin T. Evaluation of post-procedural biomarker blood draws in local laboratories are not mandated but may be performed as part of standard of care. During the index hospitalization, patients will undergo a clinical assessment and 12-lead ECG; and they will have cardiac biomarkers drawn before the intervention to establish baseline biomarker level and confirmation that the biomarkers are falling. At least one post procedure biomarker (core lab) will be drawn at a minimum of 4 hours after PCI as part of the assessment of periprocedural myocardial infarction and significant periprocedural myocardial injury (at 6-8 hour intervals depending on whether the patient remains admitted). If no procedural complications have occurred and there are no signs of ischemia on post-procedure ECG or clinical assessment, the patient may be discharged per local practice and no additional biomarker levels need to be drawn (beyond the protocol-mandated core laboratory draw at a minimum of 4 hours). If the patient remains admitted cardiac biomarkers (core lab) should be drawn every 6-8 hours until at least 2 total post-procedural core laboratory biomarker draws have passed or clinical standard-based biomarker levels have peaked per local labs or the patient is discharged. After hospital discharge, subjects will be followed at 30 days (+1 week), 6 months (+2 weeks), and 12 months (+1 month) and then 24, 36, 48 and 60 months (+1 month) post procedure. Yearly vital status information will be collected by telephone follow-up. At the 12-month visit, subjects will undergo 12-lead ECG, blood count, coagulation profile and blood chemistry tests. New and ongoing AEs and concomitant medications will also be assessed. All elective angiograms performed on the target vessel during the 12-month follow-up period should be preceded by a physician evaluation, during which the physician will indicate whether the subject's clinical status warrants revascularization, i.e. the subject has clinical evidence of ischemia.
