Revolutionizing the treatment of 
ischemic stroke and heart attack,

re-establishing blood flow faster,

without bleeding, soon in the ambulance 

Thrombolytic Science (TSci) is a private, clinical stage, vascular medicine & biotech company

Our Focus

Current treatment options for patients experiencing a stroke or heart attack are limited and delay the
re-establishment of blood flow.

TSci is dedicated to transforming standards of care, by bringing a simple intravenous biotherapy to the patient, closer to the time of onset.


TSci's bio-inspired solution is 

  • A low dose, efficacious, safer dual thrombolytic Rx

  • Based on a clinically validated mechanism

  • To be given on suspicion of a stroke or heart attack


Clinical Trials

TSci recently completed a Phase 1 clinical study confirming the safety and tolerability of its novel tPA / HisproUK dual regimen.  


TSci's dual regimen is currently being tested in a Phase 2 clinical trial in ischemic stroke patients.



tPA's biological role is limited to degrading the surface of the clot.

With TSci’s regimen, once this occurs, the small amount of tPA used is rapidly cleared from the blood flow. HisproUK, TSci's compound, exclusively targets the now degraded clot and dissolves it.


Should there be no degraded clot, as in the case of stroke mimics or a hemorrhagic stroke, HisproUK will remain safely in its inactive pro enzymatic form before being cleared in minutes from the blood flow. 


TSci's thrombolytic regimen could therefore be given safely on simple suspicion of an ischemic stroke, as soon as possible after stroke onset.
