Key result
Milvexian use after recent acute coronary syndrome is the subject of a late-breaking trial at ESC Congress 2026, with clinical results currently pending.
Expert reaction lands here the moment LIBREXIA ACS reports.
The Phase 3 LIBREXIA ACS trial evaluated milvexian, an oral factor XIa inhibitor, added to standard antiplatelet therapy in patients after acute coronary syndrome. The trial was discontinued after a preplanned interim analysis by the IDMC determined it was unlikely to meet its primary efficacy endpoint (time to first MACE). No new safety concerns were identified. Two other Phase 3 milvexian trials (Librexia AF and Librexia STROKE) continue, with data expected in 2026. Reaction has been limited to corporate statements and analyst notes, with no major independent clinical commentary yet available.
