Trial summary

Percutaneous recanalization of total coronary occlusions (TCO) was historically hampered by high rates of restenosis and reocclusion. In the PRISON II and III trial we showed landmark reduction in restenosis with sirolimus-eluting stents (Cypher, Cordis Corporation) compared to conventional bare metal stents in TCO.

About this study

Official title: Hybrid Sirolimus-eluting Stent With Bioresorbable Polymer Versus Everolimus-eluting Stent With Durable Polymer for Total Coronary Occlusions in Native Coronary Arteries (PRISON-IV)

Percutaneous recanalization of total coronary occlusions (TCO) was historically hampered by high rates of restenosis and reocclusion. In the PRISON II and III trial we showed landmark reduction in restenosis with sirolimus-eluting stents (Cypher, Cordis Corporation) compared to conventional bare metal stents in TCO. In the PRISON III trial, we observed similar favourable results with second-generation zotarolimus-eluting stent (Resolute, Medtronic Inc.). Another drugs-eluting stent mounted with everolimus (Xience Prime, Abbott) also demonstrated favourable results in TCO. Recently, drug-eluting stents (DES) with bioresorbable polymer coatings were developed, to address safety concerns regarding the observation of very late stent thrombosis, due to hypersensitivity reactions, and chronic inflammation, on the durable polymer coating of DES. However, none of these DES with bioresorbable polymers were evaluated in patients with TCO. The PRISON IV trial is a prospective, randomized, single-blinded, multi-center trial, designed to evaluate the safety, efficacy, and angiographic outcome of hybrid sirolimus-eluting stents with bioresorbable polymers (ORSIRO, Biotronik Inc.) compared to everolimus-eluting stents with durable polymers (Xience Prime, Abbott) in patients with successfully recanalized TCOs.

Read the detailed description

A total of 330 patients are randomized to either hybrid sirolimus-eluting stent or everolimus-eluting stent after successful recanalization of TCO. Clinical follow-up at 1, 6, 12 months, 2, 3, 4, 5 year with angiographic follow-up at 9 months. In 60 patients a optical coherence tomography is performed during the 9 months follow-up angiography. Quantitative coronary and optical coherence tomography analysis is performed by two independent core laboratory. The primary end point is in-segment late luminal loss at 9 month angiographic follow-up. Secondary angiographic end points include the following; in-stent luminal loss, acute recoil, acute gain, net luminal gain, late loss index, minimal lumen diameter, percentage of diameter stenosis, in-stent and in-segment binary restenosis and reocclusions at 9 months angiographic follow-up. Secondary clinical endpoints include a composite of major adverse cardiac events (death, MI and clinically driven target lesion revascularization); clinically driven target vessel revascularisation (TVR), target vessel failure (cardiac death, MI, clinically driven TVR) and stent thrombosis up to 5 year clinical follow-up. Tertiary optical coherence tomography end points at 9 months follow-up are the following: Percentage of uncovered stent struts, percentage of malapposed stent struts, tissue strut thickness, absolute and percentage of intimal hyperplasia.

Questions about this trial

What is this clinical trial studying?

A study testing Hybrid sirolimus- and everolimus-eluting stents (ORSIRO, XIENCE PRIME) in people with Coronary Artery Disease and Coronary Disease, run by R&D Cardiologie at 4 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Netherlands, Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

In-segment late luminal loss at 9 months as assessed by an independent angiographic core lab. (time frame: 9 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01516723, which also lists 16 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Aug 2026.
