Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Tenecteplase

No intervention: Standard-dose intravenous tenecteplase (0.25 mg/kg body weight) - The intervention group will receive intravenous tenecteplase as a single bolus as per the standard manufacturers' instructions for use. The dose administered will be 0.25 mg/kg body weight (maximum dose 25 mg) over 10-20 seconds as soon as possible after randomization.

Active comparator: 2) IVT with tenecteplase at low-dose: 0.18 mg/kg - The intervention group will receive intravenous tenecteplase as a single bolus as per the standard manufacturers' instructions for use. The dose administered will be 0.18 mg/kg body weight (maximum dose 18 mg) over 10-20 seconds as soon as possible after randomization.

Active comparator: 3) No IV thrombolysis [(only in those undergoing EVT or those on DOACs) - No intravenous tenecteplase only applied to subjects on DOACs over the last 24 hours or those planned for emergency EVT

Patients potentially eligible for IVT with conditions described as relative contraindications in national guidelines where physician discretion is recommended are eligible. Patients who received a DOAC, and those planned for emergency EVT are eligible.
2. Consent process completed as per national laws and regulation and the applicable ethics committee requirements.
