SIMPLAAFY Clinical Trial

Why SIMPLAAFY Clinical Trial?

The current post-implant antithrombotic therapy options include short-term OAC with a full-dose NOAC and aspirin for the first 45 days post-implant followed by P2Y12 and aspirin until 6 months post-implant or DAPT only including P2Y12 and aspirin for 6 months post implant. Patients remain on aspirin indefinitely. These current options may still carry bleeding risk during the peri-procedural period.

SIMPLAAFY is a randomized controlled trial that will evaluate two monotherapy regimens vs. DAPT after implant with the WATCHMAN FLX™ Pro Device in patients with AF. SIMPLAAFY will assess whether a less intensive drug regimen may help mitigate post-implant bleeding risk and provide other viable options for post-implant treatment.
