Bioresorbable sirolimus‑coated scaffold for new coronary artery blockages

Official title: A Bioresorbable Sirolimus-eluting scaffold Versus a Metallic Sirolimus-eluting Stent for the Treatment of de Novo Coronary Artery Lesions: a Randomized, Open-label, Non-inferiority Trial

Run by Xijing Hospital · NCT07022587 · Data updated 2026-11-12

This tests a dissolving sirolimus‑coated coronary scaffold as an alternative to metal drug‑eluting stents for adults undergoing PCI for new (de novo) coronary narrowings.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–75 with acute or chronic coronary syndrome who need PCI for a single de novo lesion sized 2.5–4.0 mm in diameter and ≤25 mm in length and who can consent and attend follow-up are ideal candidates.

Probably not a fit

Patients with severely calcified lesions, in‑stent restenosis, lesions requiring overlapping stents, left main/ostial/proximal major vessel ostial involvement, bifurcations requiring two stents, chronic total occlusion, severe vessel tortuosity, or age outside 18–75 are unlikely to benefit or are excluded.

What this trial studies

This interventional trial uses the latest Firesorb poly-L-lactic acid scaffold with an abluminal sirolimus coating to treat selected de novo coronary lesions during percutaneous coronary intervention. Eligible lesions are 2.5–4.0 mm in diameter and ≤25 mm long, and complex lesions such as severe calcification, in‑stent restenosis, bifurcations needing two stents, left main or ostial disease, chronic total occlusions, or severe tortuosity are excluded. Patients will receive the bioresorbable sirolimus‑eluting scaffold and undergo regular clinical and imaging follow-up to monitor vessel healing, scaffold performance, and safety outcomes. The protocol emphasizes optimized implantation technique and follow-up to detect late scaffold-related events.

Why it matters

Potential benefit: If successful, the device could provide temporary vessel support and drug delivery while eventually dissolving, potentially lowering late complications from permanent metal stents and restoring more natural vessel function.

How similar studies have gone: Earlier bioresorbable scaffolds such as ABSORB were linked to higher late scaffold thrombosis and are not preferred in practice, while Firesorb represents a newer, thinner‑strut design but currently has limited outcome data compared with established drug‑eluting stents.
