• The safety and effectiveness of TNKase
• In pediatric patients have not been established

In the ASSENT-2 study, 41% (3500/8458) of patients who were treated with TNKase were aged 65 years or older. In this population, rates of 30-day mortality, stroke, intracranial hemorrhage and major bleeds requiring blood transfusion or leading to hemodynamic complications were higher than in those aged less than 65 years.

TNKase is contraindicated in patients with [see Warnings and Precautions (5.1) ] : Active internal bleeding History of cerebrovascular accident Intracranial or intraspinal surgery or trauma within 2 months Intracranial neoplasm, arteriovenous malformation, or aneurysm Known bleeding diathesis Severe uncontrolled hypertension Active internal bleeding ( 4 ) History of cerebrovascular accident ( 4 ) Intracranial or intraspinal surgery or trauma within 2 months ( 4 ) Intracranial neoplasm, arteriove …

During TNKase therapy, results of coagulation tests and/or measures of fibrinolytic activity may be unreliable unless specific precautions are taken to prevent in vitro artifacts. ( 7.1 ) 7.1 Drug/Laboratory Test Interactions During TNKase therapy, results of coagulation tests and/or measures of fibrinolytic activity may be unreliable unless specific precautions are taken to prevent in vitro artifacts. Tenecteplase is an enzyme that, when present in blood in pharmacologic concentrations, remains active under in vitro conditions. This can lead to degradation of fibrinogen in blood samples removed for analysis.

Bleeding: Increases the risk of bleeding. Avoid intramuscular injections. Monitor for bleeding. ( 5.1 ) Thromboembolism: The use of thrombolytics can increase the risk of thrombo-embolic events in patients with high likelihood of left heart thrombus. ( 5.2 ) Cholesterol Embolization: Has been reported in patients treated with thrombolytic agents. ( 5.3 ) Arrhythmias: It is recommended that anti-arrhythmic therapy for bradycardia and/or ventricular irritability be available when TNKase is administered. …

The following adverse reactions are discussed in other sections of the label: Bleeding [see Contraindications (4) , Warnings and Precautions (5.1) ] Hypersensitivity [see Warnings and Precautions (5.6) ] The most common adverse reactions are bleeding and hypersensitivity.
