FDA Clears Trial Restart of Recurring Stroke Device
FDA has given Nobles Medical Technology II the green light to restart its pivotal clinical trial evaluating the NobleStitch EL system, a device-free, suture-mediated method for closing a patent foramen ovale (PFO) to reduce recurrent cryptogenic stroke. The trial was paused in 2023 over a protocol update to address observations made by FDA.
In a separate but related matter, the agency in 2024 issued a Warning Letter regarding deficiencies in the company’s monitoring and oversight of clinical studies. The letter cited the firm’s failure to obtain accurate financial disclosure information from investigators, raising concerns about the study's data validity and subject protection.
The company says the trial restart is intended to progress the company’s development program, which aims to demonstrate that PFOs — small openings between the heart’s upper chambers — can be safely and effectively closed without leaving behind a permanent implant.
NobleStitch EL is currently FDA-cleared for cardiovascular suturing and for PFO closure. It is manufactured and distributed by HeartStitch.
