Sites in EU countries currently marked recruiting
SONATA-HCMAdult obstructive + non-obstructive HCM62
CEDAR-HCMPediatric obstructive HCM4

SONATA-HCM's sponsor reported global randomization complete in July 2026, so CTIS recruiting status may overstate remaining patient competition. CEDAR-HCM is pediatric.
