Summary

This study tested a new blood thinner, abelacimab, against the standard drug apixaban in about 1,150 people with cancer who had a blood clot. The goal was to see which drug better prevented new clots and caused less bleeding. The study was stopped early, but the results may still help doctors choose safer treatments for cancer patients at risk of dangerous clots.
