SELUTION SLR™ 014 In-stent Restenosis
Study Details
Study Description
Brief Summary
Prospective, multi-center, randomized, single blind, controlled, noninferiority clinical trial.
Subjects with previous bare-metal or drug-eluting coronary stent will be randomized 1:1 to treatment with either the SELUTION SLR™ DEB or SOC to include contemporary DES (zotarolimus-eluting stents and everolimus-eluting stents only) or non-DEB BA. A maximum of 418 randomized subjects will be included. Subjects will be followed for 5 years post-intervention. Primary endpoint will be target lesion failure (TLF) determined at 12-month clinical follow-up.

Detailed Description
Prospective, multi-center, randomized, single blind, controlled, noninferiority clinical trial.
Subjects with previous bare-metal or drug-eluting coronary stent and qualifying evidence for ISR will be screened per the protocol inclusion and exclusion criteria to achieve a maximum of 418 randomized subjects (includes 5% allowance for loss to follow-up). Eligible subjects will be randomized 1:1 to treatment with either the SELUTION SLR™ DEB or SOC to include contemporary DES (zotarolimus-eluting stents and everolimus-eluting stents only) or non-DEB BA. A maximum of 20% of patients randomized to SOC will be treated with BA.
Randomization will be stratified by DES or bare-metal stent (BMS) ISR and whether there has been previous repeat stenting of target lesion. Subjects with > 2 previous repeat stent procedures involving the target lesion will be excluded.
The study will test for noninferiority of DEB versus SOC and additionally noninferiority of DEB vs DES.
Primary endpoint will be target lesion failure (TLF) determined at 12-month clinical follow-up.
After initial randomized treatment subjects in the SOC group may receive DEB (including SELUTION SLR™) treatment for recurrent clinical restenosis requiring a repeat target lesion revascularization (TLR) (i.e. after the study primary endpoint has been failed).
A subset of subjects (120 subjects including the first 60 randomized in the United States (US) and first 60 randomized in Europe who receive successful study treatment) will undergo planned angiographic follow-up at 12-13 months after completion of primary endpoint clinical follow-up/assessment.
At 12-13 months, and after clinical primary endpoint has been assessed, a subset of the angiographic follow-up cohort (~60) will also undergo planned optical coherence tomography (OCT) follow-up, 30 United States (US) and 30 Europe.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: SELUTION SLR™ DEB
|
Device: SELUTION SLR™ DEB
The SELUTION Sustained Limus Release (SLR)™ drug-eluting balloon (DEB) catheter is a combination product consisting of a standard percutaneous transluminal angioplasty (PTA) balloon catheter coated with a drug (Sirolimus). The drug coating is formulated with Sirolimus microspheres suspended in a phospholipid blend. The balloon catheter component of the SELUTION SLR™ DEB is a conventional single use, sterile, rapid exchange catheter to dilate vascular lesions. The semi-compliant balloon is inflated for 60 seconds (minimum of 30 seconds) to transfer the Sirolimus loaded microspheres to the target vessel wall. The balloon is then deflated and removed from the body.

| Active Comparator: Control Treatment For subjects randomized to the control group (SOC) the treating physician may chose to implant a commercially available DES or alternatively may use POBA only to treat the patient. The decision should be based on the treating physicians' assessment of the best treatment option for the individual patient. However, it is expected that patients with one prior stent will receive DES and patients with two prior stents will receive POBA. Treating physicians may deviate from this if it is determined to be in the best interest of the patient, but the justification for the treatment decision must be recorded in eCRF. Choice of DES is at the treating physician's discretion, but is limited to ZES and EES devices. |

Outcome Measures
Primary Outcome Measures
- Target Lesion Failure [12 months post-index procedure]
The primary endpoint for effectiveness is target lesion failure (TLF) rate at 12 months post-index procedure. TLF is defined as a composite of: all cardiac death, target vessel myocardial infarction (SCAI definition), and clinically driven TLR.
Secondary Outcome Measures
- In-segment minimal luminal diameter (MLD) [at 12 months]
The powered secondary endpoint will be in-segment minimal luminal diameter (MLD) at 12 months (after documented completion of 12 months of clinical follow-up) in the angiographic follow-up subset.
- Device success [at 12 months]
Attainment of < 30% residual stenosis of the target lesion using the assigned study treatment only.
- Lesion Success [at 12 months]
Attainment of < 30% residual stenosis of target lesion using any percutaneous method.
- Procedure Success [at 12 months]
Attainment of < 30% residual stenosis of the target lesion using the assigned study device only without occurrence of in-hospital MACE.
