Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
1. Patient must be at least 18 years of age
2. Patient is able to understand the risks, benefits and treatment alternatives of receiving the DynamX Sirolimus Eluting CBS and provide written informed consent, as approved by the NZ Ethics Committee, prior to any clinical study-related procedure
3. 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)
4. Patient must be an acceptable candidate for coronary artery bypass graft (CABG) surgery
5. Women of childbearing potential with a negative pregnancy test within 7 days and women who are not pregnant or nursing
6. Patient must agree to undergo all clinical study required follow up visits, angiograms, and imaging testing
7. Patient must agree not to participate in any other clinical research study for a period of one year following the index procedure Angiographic inclusion criteria- Target Lesion/Vessel
8. Target lesion(s) must be located in a native coronary artery with a vessel diameter of = 2.5 and =3.5 mm assessed visually or by online QCA
9. Target lesion(s) must measure = 24 mm in length
10. Target lesion(s) must be in a major artery or branch with a visually estimated stenosis of = 50% and < 90% with a TIMI flow of = 2. When two target lesions are treated, they must be located in separate major epicardial vessels
11. The lesion(s) must be successfully pre-dilated (less than 35% DS) prior to enrollment
12. The target lesion length is 24 mm and able to be covered by a single DynamX Sirolimus Bioadaptor with 2 mm of healthy vessel on either side of planned implantation site
13. Treatment of a single, non-target lesion located in a separate major epicardial vessel
Minimum age
18 Years
Maximum age
80 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Patient has a diagnosis of ST elevation myocardial infarction (STEMI) within 72 hours preceding the index procedure, and CK and CK-MB have not returned within normal limits at the time of procedure
2. Patient requires the use of rotational atherectomy during the index procedure
3. Patient has current unstable ventricular arrhythmias
4. Patient has a known left ventricular ejection fraction (LVEF) < 30%
5. Patient has received a heart transplant or any other organ transplant or is on a waiting list for an organ transplant
6. Patient is receiving or scheduled to receive chemotherapy for malignancy within 30 days prior to or after the procedure
7. Patient is receiving immunosuppression therapy, other than steroids or has known immunosuppressive or autoimmune disease (e.g. human immunodeficiency virus, systemic lupus erythematosus etc.)
8. Patient has a known hypersensitivity or contraindication to aspirin, both heparin and bivalirudin, clopidogrel, prasugrel or ticagrelor, Sirolimus, CoCr alloys, PLLA polymers or contrast sensitivity that cannot be adequately pre-medicated
9. Elective surgery is planned within the first 6 months after the procedure that will require discontinuing either aspirin or clopidogrel or other P2Y12 inhibitors.
10. Patient has a platelet count < 100,000 cells/mm3 or > 700,000 cells/mm3, a WBC of < 3,000 cells/mm3, or documented liver disease.
11. Patient has severe renal dysfunction (CKD IV or V, eGFR <30) or is on dialysis.
12. Patient has a history of bleeding diathesis or coagulopathy or will refuse blood transfusions
13. Patient has had a cerebrovascular accident (CVA) or transient ischemic neurological attack (TIA) within the past six months
14. Patient has had a significant GI or urinary bleed within the past six months
15. Patient has a condition that precludes safe 6 French sheath insertion; or other medical conditions or known history of substance abuse (alcohol, cocaine, heroin etc.) that may cause non-compliance with the clinical study plan, confound the data interpretation or associated with a limited life expectancy (i.e., less than one year)
16. Patient is already participating in another clinical study which has not reached the primary endpoint (long-term follow-up is not an exclusion) Angiographic Exclusion Criteria Target Lesion/Vessel

1. Target/Vessel / Target lesion(s) meets any of the following criteria:

1. Aorto-ostial location
2. Left main location
3. Located within 5 mm of the origin of the LAD or LCX
4. Located within an arterial or saphenous vein graft or distal to a diseased arterial or saphenous vein graft
5. Lesion involving a bifurcation with a side branch >2mm in diameter
6. Previous placement of a stent within 10 mm of the target lesion
7. Total or sub-total occlusion (TIMI flow =1)
8. The proximal target vessel or target lesion is severely calcified by visual assessment, or the lesion prevents full pre-dilatation balloon expansion
9. Previous intervention restenosis 2. The target vessel contains visible thrombus 3. Another clinically-significant lesion (>50%) is located in the same major epicardial vessel as the target lesion 5. Target vessel was previously treated with any type of PCI < 6 months prior to index procedure 6. Non-Target vessel was previously treated with any type of PCI < 30 days prior to the index procedure
