A stroke occurs when the blood supply to brain tissue is blocked by a blood clot (ischemic stroke), or when a blood vessel in the brain ruptures (hemorrhagic stroke), causing brain cells to die and leading to functional impairments. Stroke is a leading cause of death and disability both globally and in the U.S., where approximately 800,000 people experience a stroke each year1.

Comparison of TNK With Wild-Type Tissue Plasminogen ...

Mar 01, 2001·Wild-type tissue plasminogen activator (tPA) is an effective thrombolytic therapy for stroke patients, despite an increased rate of cerebral hemorrhage. 1 2 Tenecteplase (TNK) is a genetically modified form of wild-type tPA, which seems to produce more rapid and complete thrombolysis. TNK has a longer biological half-life and is 14 times more fibrin specific than tPA. 3 The …
