Thrombocheck: a drug-drug interactions guide for cardiologists prescribing antithrombotic therapy (ESC-WCC 2025) - " First, a clinical pharmacist and a physician independently analysed the literature on DDI for 8 AT: 5 OAC (rivaroxaban, apixaban, edoxaban, dabigatran and acenocoumarol) and 3 AA (clopidogrel, ticagrelor and prasugrel). Aspirin was excluded as it is not known for PK DDI... Antithrombotic therapies are susceptible to numerous DDI. This simple yet important tool can help cardiologists minimize significant DDI when prescribing new AT, guiding them toward safer et more effective treatment options."

The key determinants of oral anticoagulant treatment experience in atrial fibrillation patients (ESC-WCC 2025) - "NOACs were used by 53% of patients, mainly rivaroxaban (38%), apixaban (11%), and edoxaban (4%), while 47% used VKAs, primarily warfarin (25%) and acenocoumarol (22%). The study highlights that socioeconomic factors, particularly education level and household income, play a crucial role in the perceived convenience and satisfaction with OAC therapy in AF patients. Patients receiving VKA therapy reported lower treatment convenience, possibly due to the need for frequent monitoring and dietary restrictions.These findings underscore the importance of individualized patient support and education to optimize adherence and overall treatment experience in anticoagulated AF patients."

Comparative clinical outcomes of acenocoumarol versus direct oral anticoagulants (DOACs) and warfarin in patients with atrial fibrillation: real-world-evidence (SIESTA-A study). (PubMed, Front Pharmacol) - "The aim of this study was to evaluate the effectiveness and safety of direct oral anticoagulants (DOACs: dabigatran, rivaroxaban, apixaban and edoxaban) and warfarin versus acenocoumarol in patients with atrial fibrillation under real-world clinical practice conditions. Although DOACs were clearly associated with a lower risk of intracranial bleeding compared to acenocoumarol, our data did not reveal a significant reduction in thromboembolic events. Warfarin was found to be both less effective and less safe than acenocoumarol."

A PHASE IB, MULTICENTRE, OPEN-LABEL, DOSE-ESCALATION STUDY TO EVALUATE THE SAFETY, TOLERABILITY, PHARMACOKINETICS AND PHARMACODYNAMICS OF SUBCUTANEOUSLY ADMINISTERED MOSUNETUZUMAB IN PARTICIPANTS WITH SYSTEMIC LUPUS ERYTHEMATOSUS (EULAR 2025) - P1 | "Four of 15 patients experienced a total of 5 cytokine release syndrome (CRS) events; all were Grade 1-2 and none required tocilizumab administration...One patient receiving concomitant acenocoumarol experienced a transient increase in international normalised ratio due to expected cytochrome P450 inhibition by transient cytokine release, requiring acenocoumarol dose adjustment... Preliminary data from this Phase Ib study indicated that mosunetuzumab exhibits an acceptable safety profile in patients with SLE and that its PK profile in the SLE population is closely aligned with that observed in the relapsed or refractory NHL population. Deep B-cell depletion in the higher-dose cohorts demonstrated the potential for treating B-cell–driven autoimmune diseases. Whilst this study was designed to evaluate the safety and PK profile of mosunetuzumab with a limited dosing regimen, there did appear to be a positive impact on clinical activity."
