Vortosiran in Atrial Fibrillation

This is a randomised, actively controlled Phase IIb trial to evaluate the safety and pharmacodynamics (PD) of two blinded doses of subcutaneously administered vortosiran and open-label apixaban in patients with AF. The trial consists of three groups including 50 participants each. The participants will be randomized to either the low dose group or the high dose group receiving vortosiran or to the group receiving apixaban. The treatment will be open-label for vortosiran vs apixaban. The vortosiran dose will be blinded to patients and investigators. Both the low- and the high-dose group will receive two doses of vortosiran, the first dose at Day X and the second at Day Y. After 24 weeks, at the end of the vortosiran treatment period, the participants will start an open-label part of the trial and will be switched to standard-of-care apixaban treatment until Week 64 (End of Trial; EOT). Participants in the open-label apixaban arm will receive apixaban as standard of care during the entire trial.

WATCHMAN FLX Pro European Registry

The WATCHMAN FLX Pro European registry is intended to gather real world clinical data for patients undergoing left atrial appendage closure (LAAC) with the WATCHMAN FLX™ Pro device. In a subregistry with approximately 300 patients, it is intended to use the VersaCross Connect™ LAAC Access Solution.
