Retrospective analysis showed longer OS in AYVAKIT patients, including in SM - AHN where clinical practice has historically prioritized AHN treatment A multi - center, global, observational, retrospective chart review study was conducted at 6 study sites (4 European, 2 US) to ide ntify and collect data from AdvSM patients who received BAT. SM - AHN patients were identified using inclusion/exclusion criteria similar to the EXPLORER and PATHFINDER trials.
