eXIthera is a clinical stage biotech company focused on developing small molecule anti-thrombotics to inhibit Factor Xla, an important enzyme in the blood coagulation pathway.  


Inappropriately activated clotting can lead to serious consequences including venous thromboembolism, deep vein thrombosis, stroke and heart attack. eXIthera's novel development candidates are expected to prevent thrombosis without causing bleeding and without the need for a reversal agent, the primary complications associated with all currently approved products.  eXIthera has both parenteral and oral programs in development to facilitate a smooth transition from inpatient to outpatient treatment settings.
