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

Focus

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.

Clinical
Science

Science

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.

Results of a Phase II trial of Thrombolytic Science's low dose dual therapy vs alteplase in mild stroke patients, published in JAMA Neuro.

  • No significant difference between groups in All ICH, i.e.: asymptomatic + symptomatic ICH, the primary endpoint.

  • Secondary endpoints show positive trends in favor of a safe, low dose dual therapy

    • No symptomatic ICH

    • Less disability

    • No fibrinogen depletion, i.e.: less risk of bleeding

Authors conclude further exploration in more severe stroke patients is warranted.
