Yonah S. Tehrani: Providing Clarity for Anticoagulant Selection in Acute Venous Thromboembolism
Yonah S. Tehrani, Physician at Shaare Zedek Medical Center, Jerusalem, shared a post on LinkedIn about a recent article by Lana A. Castellucci et al, published in New England Journal of Medicine:
”Recent head-to-head data from the COBRRA trial (NEJM, March 2026) provides much-needed clarity for anticoagulant selection in acute venous thromboembolism.
In this randomized study of >2,700 patients with symptomatic PE or proximal DVT, apixaban (standard dosing) was associated with a significantly lower rate of clinically relevant bleeding compared with rivaroxaban over 3 months (3.3% vs 7.1%; RR 0.46, p<0.001), with no difference in recurrent VTE.
These findings have direct implications for daily clinical decision-making: when balancing efficacy and safety — particularly in older adults, patients with renal impairment, or those at elevated bleeding risk — apixaban now offers a clear safety advantage without compromising antithrombotic protection.
At the system level, preferential use could translate to reduced bleeding-related hospitalizations, lower transfusion rates, and more confident outpatient PE management.
Important to note the open-label design and potential contribution of dosing regimen differences, but the magnitude of effect is clinically meaningful and should inform local protocols and shared decision-making discussions.
What are your thoughts?
Has this data already shifted prescribing patterns in your institution?
Looking forward to the discussion.”
