S01E27 | Apixaban vs Rivaroxaban in Acute VTE: The COBRRA Trial
from PRISM Rounds: Pulmonary, Critical Care & Sleep Medicine
In this episode of PRISM Rounds, we break down the new NEJM 2026 COBRRA trial comparing apixaban vs rivaroxaban for acute venous thromboembolism (VTE).Bottom line: in this randomized head-to-head trial, apixaban reduced clinically relevant bleeding compared with rivaroxaban (3.3% vs 7.1%; RR 0.46), including lower major bleeding (0.4% vs 2.4%), with similar observed recurrent symptomatic VTE rates (1.1% vs 1.0%) over 3 months.
