NCT ID NCT07373353

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests a new device called AMJ-401 in 50 people with ischemic heart disease (blocked heart arteries) in Japan. Participants receive the device during a standard procedure to open blocked arteries. The main goals are to check for acute strut fractures right after the procedure and to see how well the device is covered by tissue after 6 months. This is an early-stage trial focused on safety and device performance.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
AMJ-401 device
What this could lead to
If successful, this device could improve outcomes for patients with blocked heart arteries by reducing complications like strut fractures.
What could go wrong
This is a small, early-phase study with only 50 participants. It focuses on device performance, not long-term patient benefits. The device may not show clear advantages over existing stents.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria 1. Subject must be at least 18 years of age. 2. Subject or a legally authorized representative must be able to provide written Informed Consent prior to any study related procedure, per site requirements. 3. Subject must have evidence of myocardial ischemia (e.g., stable angina, silent ischemia, unstable angina, acute myocardial infarction) suitable for elective PCI. 4. Subject must be an acceptable candidate for coronary artery bypass graft (CABG) surgery. 5. Subject must be able to take dual antiplatelet therapy (DAPT) for minimum of 12 months following the index procedure and anticoagulants prior/during the index procedure, and the subject has no known allergic reaction, hypersensitivity or contraindication to aspirin, clopidogrel, prasugrel, ticagrelor, ticlopidine or heparin. 6. Female subjects of childbearing potential must not be pregnant\* at screening and do not plan pregnancy for at least 12 months following the index procedure. \* Female subjects of child-bearing potential must have a negative pregnancy result within 7 days prior to the index procedure. 7. Female subjects must not be breast-feeding at the time of the screening visit and will not be breast-feeding for at least 12 months following the index procedure. 8. Subject agrees to not participate in any other investigational or invasive clinical study for a period of 13 months following the index procedure. Exclusion Criteria: 1. Elective surgery planned within 12 months after the procedure that will require general anesthesia or discontinuing either aspirin or P2Y12 inhibitor. 2. Subject has known hypersensitivity or contraindication to device material and its degradants (everolimus, PLLA, PDLLA, platinum, lactic acid, and lactide) that cannot be adequately pre-medicated. 3. Subject has a known contrast sensitivity that cannot be adequately pre-medicated. 4. Subject with known diagnosis of ST-elevation myocardial infarction (STEMI) within 72 hours of the index procedure. 5. The subject is currently experiencing clinical symptoms consistent with new onset acute myocardial infarction (AMI), such as nitrate-unresponsive prolonged chest pain with ischemic ECG changes. 6. Subject has an unstable cardiac arrhythmia which is likely to become hemodynamically unstable due to their arrhythmia 7. Subject has a known left ventricular ejection fraction (LVEF) \< 30% (LVEF may be obtained at the time of the index procedure prior to subject registration if the value is unknown and the site Investigator believes it is necessary). 8. The target vessel was treated by PCI within 12 months prior to index procedure. 9. Prior PCI within the non-target vessel is acceptable if performed anytime \> 30 days before the index procedure, or between 24 hours and 30 days before the index procedure if successful and uncomplicated. 10. Subject requires future staged PCI either in target or non-target vessels. 11. Subject has a malignancy that is not in remission. 12. Subject is receiving immunosuppressant therapy or has known life-threatening immunosuppressive or life-threatening autoimmune disease (e.g., human immunodeficiency virus, systemic lupus erythematosus, etc.). Note: corticosteroids are not included as immunosuppressant therapy, diabetes mellitus is not regarded as autoimmune disease. 13. Subject has received any solid organ transplants or is on a waiting list for any solid organ transplants. 14. Subject has previously received or scheduled to receive radiotherapy to coronary artery (brachytherapy), or chest/mediastinum. 15. Subject is receiving or will require chronic anticoagulation therapy (e.g., warfarin). 16. Subject has a platelet count \< 100,000 cells/mm3 or \> 700,000 cells/mm3. 17. Subject has documented or suspected cirrhosis of Child-Pugh ≥ Class B. 18. Subject has known renal insufficiency: * Dialysis at the time of screening or * An estimated GFR \< 30 ml/min/1.73m2 19. Subject has a high risk of bleeding, or; * Subject has a history of bleeding diathesis or coagulopathy. * Subject has had a significant gastro-intestinal or significant urinary bleed within the past six months. * Subject has prior intracranial bleed (including severe permanent neurologic deficit that seems to be caused by previous intracranial bleeding). * Subject has known intracranial pathology that may cause intracranial bleeding per investigator assessment (e.g., untreated aneurysm greater than 5 mm, arteriovenous malformation) * Subject will refuse blood transfusions. * Subject is receiving antiplatelet medication other than aspirin or P2Y12 inhibitor for the treatment of another condition and cannot discontinue them 20. Subject has had a cerebrovascular accident or transient ischemic neurological attack (TIA) within the past six months, 21. Subject has extensive peripheral vascular disease that precludes safe 6 French sheath insertion via any vessel. 22. Subject has life expectancy \< 3 years. 23. Subject is in the opinion of the Investigator or designee, unable to comply with the requirements of the study protocol or is unsuitable for the study for any reason. 24. Subject is currently participating in another clinical trial that has not yet completed its primary endpoint. 25. Subject whose willingness to volunteer in a clinical investigation could be unduly influenced by the expectation, whether justified or not, of benefits associated with participation or of retaliatory response from senior members of a hierarchy in case of refusal to participate (e.g., subordinate hospital staff or sponsor staff).
