Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The ORION study is being conducted to determine whether the Epic™ Nitinol Stent for primary stenting of iliac atherosclerotic lesions shows acceptable performance at 9 months.
Detailed description
ORION is a prospective, single arm, non-randomized, multicenter study. A subject could receive a maximum of 2 study stents for up to 2 target lesions. A maximum of 1 non-target lesion in 1 non-target vessel could be treated with a commercially approved treatment during the index procedure.

- Adult, Older adult
Key inclusion criteria (10 listed)
- Documented chronic, symptomatic iliac artery atherosclerotic disease (Rutherford/Becker category 1, 2, 3 or 4)
- Lifestyle-limiting claudication or rest pain
- De novo or restenotic lesions in the common and/or external iliac artery
- Subjects with bilateral disease may have only one target lesion treated per side
- Two target lesions may be treated with a maximum of two stents (if two target lesions are treated, each lesion must be covered with a maximum of one stent)
Key exclusion criteria (21 listed)
- Target vessel with in-stent restenosis
- Acute critical limb ischemia
- Tissue loss (Rutherford/Becker category 5 or 6)
- Any major amputations to the target limb
- Any minor amputation of the target limb in the last 12 months. If a minor amputation occurred greater than 12 months, stump needs to be completely healed.
Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.
Interventions
| Intervention | Type | Arms |
|---|---|---|
| Epic™ Nitinol Stent SystemThe Epic™ Nitinol Stent System is comprised of two components: the implantable nitinol endoprosthesis and the stent delivery system. | Device | ORION |
| Anti-platelet therapyInvestigators must prescribe concomitant anti-platelet medication consistent with current clinical practice. Anti-platelet therapy should be administered preprocedure and continued throughout participation in the trial. | Drug | ORION |
| Anti-coagulation therapyAnti-coagulation therapy must be administered during the procedure consistent with current clinical practice. | Drug | ORION |

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Epic™ Nitinol Stent System, Anti-platelet therapy and Anti-coagulation therapy in people with Iliac Artery Stenosis, run by Boston Scientific Corporation at 28 sites in United States.
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 10 inclusion and 21 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 7 May 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 28 sites in United States. 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.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 3 Jul 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Device- and/or Procedure-related Major Adverse Events (MAE) (time frame: 9 Months). 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 NCT00896337, which also lists 1 linked publication.
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 7 May 2015.
