Laminær LAAX Pivotal IDE-undersøgelse

14. oktober 2026 opdateret af: Jaguar LAA, Inc.

Laminar venstre atriel appendage Elimination (LAAX) pivotal IDE-undersøgelse

The purpose of this study is to compare the safety and effectiveness of Laminar Left Atrial Appendage Closure (LAAC) device as compared to the commercially available LAAC devices in participants with non-valvular atrial fibrillation (NVAF) to reduce the risk of stroke (blocked blood vessel or bleeding in brain) and systemic embolism (blockage in a blood vessel harming vital organs).

Detaljeret beskrivelse

This prospective, randomized, controlled, multicenter, open-label pivotal clinical study will enroll participants with non-valvular atrial fibrillation who are eligible for short-term anticoagulation therapy but have a rationale to seek non-pharmacologic alternative. Participants will be randomized 1:1 to the Laminar Left Atrial Appendage Closure System or commercially available device (WATCHMAN™ left atrial appendage closure device / Amulet™ left atrial appendage occluder).

  • Eligible for the protocol-specified post-procedural antithrombotic regimen
  • Willing and able to comply with the protocol, and has provided written informed consent (participant or legally authorized representative) per institutional review board (IRB) requirements

Exclusion Criteria:

  • Single episode, transient, or reversible atrial fibrillation (AF) (example, secondary to thyroid disorders, acute alcohol intoxication, trauma, recent major surgical procedures)
  • Prior cardiac surgery or any procedure that involved pericardial access
  • Stage IV kidney disease or Renal insufficiency, defined as estimated glomerular filtration rate (eGFR) less than (<) 30 milliliters per minute per (mL/min)/1.73 square meters (m^2) or participants with end stage renal disease who are dialysis dependent
  • Any cardiac or non-cardiac interventional or surgical procedures within 60 days prior to or any planned general surgery, cardiac surgery, or interventional procedure within 60 days after implant (including, but not limited to cardioversion, percutaneous coronary intervention (PCI), cardiac ablation, cataract surgery)
  • Left atrial appendage anatomy which cannot accommodate either commercially available control device or the laminar implant per manufacturer instructions for use (IFU) (that is, the anatomy and sizing must be appropriate for a control and the Laminar device to be enrolled in the study)

Type V

  1. Type Va: Probable fatal bleeding; no autopsy or imaging confirmation but clinically suspicious.

Up to 12 months
Number of Participants With Pericardial Effusion Requiring Drainage
Tidsramme: Up to 12 months

Pericardial effusion is defined as 1) Clinically non-relevant: requiring no intervention, treated pharmacologically and 2) Clinically relevant: treated with therapeutic intervention (pericardiocentesis, surgical intervention, blood transfusion) and/or result in shock or death.

Up to 12 months
Number of Participants With Device Embolization
Tidsramme: Up to 12 months

Participants with device embolization will be reported. Device embolization is defined as movement of a medical device to an unintended location within the body with resulting obstruction of an organ or vessel.

Up to 12 months
Number of Participants With Device or Procedure-Related Events Requiring Open Cardiac Surgery or Major Endovascular Intervention

Tidsramme: Up to 18 Months

Participant reporting ischemic stroke or systemic embolism will be reported. Systemic embolism is defined as acute vascular insufficiency or occlusion of the extremities or any non-CNS organ associated with clinical, imaging, surgical/autopsy evidence of arterial occlusion in the absence of other likely mechanism (example; trauma, atherosclerosis, or instrumentation).

Up to 18 Months

Peri-Device flow is defined as >= 3 mm in width which communicates beyond the device into the body of the left atrial appendage) per transesophageal echocardiogram (TEE) evaluated by independent core laboratory.

Up to 12 Months
Rate of Device-Related Thrombosis
