FDA Clearance Information

Pathway ? PMA
Number ? P110010 ↗
Decision Date ? November 19, 2020
Product Code ? NIQ
Device Class ? Class 3
Evidence ? 0 studies

The Promus Premier stent received FDA clearance through the PMA pathway on November 19, 2020. Manufactured by Boston Scientific, it is classified as a Class III medical device.

What It Is

The Promus Premier is a drug-eluting stent that releases everolimus to prevent restenosis in coronary arteries. It is made from platinum chromium, offering improved conformability and radiopacity.

FDA-Cleared Indications

  • Modification to the midshaft adhesive bond length.

Clinical Applications

  • Use within the coronary arteries as part of a coronary stent system.
  • Placement after percutaneous coronary intervention to support the treated coronary segment.
  • Delivery of everolimus from a drug-eluting coronary stent system.

Reported off-label uses

  • Use in selected coronary anatomy or clinical situations outside the specific approved labeling may occur in practice, but such use should be determined by the treating interventional cardiologist.

Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.

Evidence Summary

The literature includes randomized controlled trials and observational studies, with a focus on real-world applications. Approximately 7 studies span from 2018 onwards, evaluating safety and efficacy.

Reported Outcomes

Published studies report that the Promus Premier stent demonstrates improved radial strength and conformability compared to older stent models. Clinical outcomes indicate effective prevention of restenosis with a favorable safety profile.

Safety Profile

Reported complications include typical stent-related issues such as thrombosis and restenosis, though the incidence is low. The safety profile is consistent with other drug-eluting stents.

Evidence Limitations

Current evidence is limited by the lack of long-term follow-up data and the need for more diverse population studies. Further research is needed to assess long-term outcomes and safety in varied clinical settings.

Practical Considerations

  • The system is a balloon-expandable, everolimus-eluting stent made with a platinum chromium platform; available diameters and lengths depend on the specific product configuration.
  • It is delivered through a compatible coronary guide catheter and guidewire during fluoroscopic angiography; vessel preparation and accurate sizing are important.
  • Patients generally require antiplatelet medication after placement. The treating cardiologist determines the drug regimen and duration.
  • MRI conditions should be confirmed in the current device labeling before scanning; the stent is not automatically safe for every MRI setting or protocol.
  • Contraindications and precautions include unsuitable vessel anatomy, inability to receive required antiplatelet therapy, significant bleeding risk, and known sensitivity to device or drug components.
