Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
General Inclusion Criteria:
- Patient must be at least 18 years of age.
- Patient is able to verbally confirm understanding of risks, benefits and treatment alternatives of receiving the DynamX Novolimus Eluting Coronary Stent System (CSS) and he/she provides written informed consent, as approved by the appropriate Ethics Committee of the respective clinical site, prior to any clinical study related procedure.
- Patient must have evidence of myocardial ischemia (e.g., stable or unstable angina, silent ischemia, positive functional study or electrocardiogram (ECG) changes consistent with ischemia)
- Patient must be an acceptable candidate for coronary artery bypass graft (CABG) surgery
- Patient must agree to undergo all clinical study required follow-up visits, angiograms, and IVUS testing
- Patient must agree not to participate in any other clinical study for a period of one year following the index procedure.
Angiographic Inclusion Criteria - Target Lesion/Vessel
- Target lesion must be located in a native coronary artery with a nominal vessel diameter of ≥ 2.5 and ≤3.5 mm assessed visually or by online QCA
- Target lesion must measure ≤ 24 mm in length
- Target lesion must be in a major artery or branch with a visually estimated stenosis of ≥ 50% and < 90% with a TIMI flow of ≥ 2
- The lesion must be successfully pre-dilated (less than 35% DS) prior to enrollment
Angiographic Inclusion Criteria - non-Target Lesion/Vessel Treatment
- Treatment of a single, non-target lesion located in a separate major epicardial vessel (defined as LAD with septal and diagonal branches, LCX with obtuse marginal and/or ramus intermedius branches and RCA and any of its branches) attempted during the index procedure must be completed first using an approved 'olimus drug eluting stent. The segment must be located such that any injury that might occur during intervention can be clearly attributable to the treated non-target vessel. If the procedure is deemed uncomplicated and optimal, treatment of the target lesion with the DynamX stent can be considered.
Optimal lesion/vessel treatment defined as:
- < 10% but no more than 15% residual diameter stenosis by visual assessment
- no evidence of dissection
- no evidence of thrombus in the treated lesion or vessel
- TIMI 3 flow
- Stent completely covers lesion and extends to healthy vessel on both sides (healthy to healthy)
General Exclusion Criteria
- Patient has a known diagnosis of acute myocardial infarction (AMI) within 72 hours preceding the index procedure and CK and CK-MB have not returned within normal limits at the time of procedure
- Patient is currently experiencing clinical symptoms consistent with AMI
- Patient requires the use of any rotablator intervention during the index procedure
- Patient has current unstable arrhythmias
- Patient presenting with heart failure, chronic arrhythmia, COPD or lung function impairment

- Patient is receiving immunosuppression therapy and has known immunosuppressive or autoimmune disease (e.g. human immunodeficiency virus, systemic lupus erythematosus etc.)
- Patient is receiving chronic anticoagulation therapy (e.g., heparin, coumadin) that cannot be stopped and restarted according to local hospital standard procedures.
- Patient has a known hypersensitivity or contraindication to aspirin, both heparin and bivalirudin, clopidogrel, prasugrel or ticagrelor, Novolimus, CoCr alloys, PLLA polymers or contrast sensitivity that cannot be adequately pre-medicated
- Elective surgery is planned within the first 6 months after the procedure that will require discontinuing either aspirin or clopidogrel or other P2Y12 inhibitors.

- Located within an arterial or saphenous vein graft or distal to a diseased arterial or saphenous vein graft
- Lesion involving a side branch >2mm in diameter or bifurcation
- Previous placement of a stent proximal to or within 10 mm of the target lesion
- Total or sub-total occlusion (TIMI flow ≤ 1)
- Excessive tortuosity or angulation (≥ 45o) proximal to or within the lesion
- The proximal target vessel or target lesion is moderately or severely calcified by visual assessment, or lesion prevents full pre-dilatation balloon expansion

Official title: Evaluation of a Thin Strut Metallic Stent: the Elixir DynamXTM Novolimus Eluting Coronary Bioadaptor System
The DynamX (Bioadaptor) study is a prospective, consecutive enrollment study designed to enroll up to 50 patients requiring treatment of a single, de novo lesion ≤ 24 mm in length located in a vessel ≥ 2.5 mm and ≤ 3.5 mm in diameter. All patients be followed clinically at 30 days, 6 and 9 months, and 1, 2 and 3 years.
All patients will undergo imaging (angiography and IVUS) follow-up with approximately one-half of the patients returning for follow up at 9 months and approximately one-half returning for follow up at 12 months.

The DynamX (Bioadaptor) study is a prospective, consecutive enrollment study designed to enroll up to 50 patients requiring treatment of a single, de novo lesion ≤ 24 mm in length located in a vessel ≥ 2.5 mm and ≤ 3.5 mm in diameter. All patients be followed clinically at 30 days, 6 and 9 months, and 1, 2 and 3 years.
All patients will undergo imaging (angiography and IVUS) follow-up with approximately one-half of the patients returning for follow up at 9 months and approximately one-half returning for follow up at 12 months.
At select centers, a subset of approximately 20 patients will undergo FFR pressure wire measurement at baseline and at follow-up (or at a minimum follow-up) in conjunction with the IVUS imaging, and will also undergo OCT imaging at 9 or 12 months.
The primary safety endpoint is Target Lesion Failure at 6 months. TLF is a composite endpoint defined as cardiac death, target vessel MI, and clinically-indicated target lesion revascularization.
The primary imaging/efficacy endpoints for those patients undergoing imaging follow-up is the change in mean in-device area and mean lumen area at 9 or 12 months compared to post-procedure as measured by IVUS.
Co-primary imaging/efficacy endpoints for those patients undergoing imaging follow-up is late lumen loss as measured by QCA and IVUS at 9 or 12 months.

Questions about this trial
What is this clinical trial studying?
A study testing Percutaneous Coronary Intervention in people with Coronary Artery Disease, run by Elixir Medical Corporation at 2 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?
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 20 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Belgium, Italy. 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?
Target Lesion Failure (TLF) (time frame: 6 months). The study lists 5 primary outcomes in all. 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 NCT03429894, 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 20 Jul 2022.
