FDA-approved Investigator-initiated Pre-market Clinical Trial of LAmbre™ Plus LAA Closure System Obtained Medical Insurance Coverage in the US

SHENZHEN,China,Sept. 5,2022 -- LifeTech Scientific Corporation (Stock Code: 1302.HK) is pleased to announce that on 30 August 2022,an FDA-approved investigator-initiated pre-market clinical trial of its proprietary LAmbre™ Plus Left Atrial Appendage (LAA) Closure System has obtained medical insurance coverage in the United States,meaning that all patient enrollment of the clinical trial will be fully covered by the USA medical insurance. This is expected to facilitate the marketing and registration process of the innovative device in the United States and provide strong clinical data to support the development of the device in the global market.

The investigator-initiated pre-market clinical trial received FDA approval in March 2022.This prospective,randomized,controlled,multicenter clinical trial aims to evaluate the safety and efficacy of the implantation of LAmbre™ Plus LAA occluder in non-valvular atrial fibrillation patients with large and/or irregularly shaped appendages,as compared to oral anticoagulants.The trial is planning to enroll more than 3,000 subjects from up to 75 investigational sites in the United States and undertake more than 1,500 implantations of the LAmbre™ Plus LAA occluders at a fee. After reaching the established clinical objectives and conditions,the company will submit the marketing application of the device to the FDA.

"This is a great milestone in LifeTech's international roadmap. Our LAA occluders had been successfully implanted in the United States on a basis of 'compassionate use',providing a new treatment for non-valvular atrial fibrillation patients with irregularly shaped appendages. Today,the approval for the first ever USA based investigator-initiated pre-market clinical trial and the medical insurance coverage gives us a greater confidence to further accelerate our process for providing this innovative,safe and effective stroke prevention solution to patients in the United States," said Mr. Xie Yuehui,Chairman and CEO,LifeTech Scientific Corporation.
