Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Low-dose rtPA (Recruitment completed in August 2015)
low-dose 0.6 mg/kg (maximum of 60 mg) i.v. rtPA
Low-dose rtPA
Patients allocated to low-dose will receive 0.6 mg/kg (maximum of 60 mg) i.v. (15% bolus \[maximum bolus dose of 9mg\] and 85% infusion over 60 mins) recombinant tissue plasminogen activator (rtPA).
Standard-dose rtPA (Recruitment completed in August 2015)
standard-dose 0.9 mg/kg (maximum of 90 mg) i.v. rtPA
Standard-dose rtPA
Patients allocated to standard-dose will receive 0.9 mg/kg (maximum of 90 mg) i.v. (10% bolus and 90% infusion over 60 mins) rtPA.
Early intensive BP lowering
The trial is an assessment of BP lowering management strategies, using routinely available drugs.
Intensive blood pressure (BP) lowering to a target systolic BP range 130-140 mmHg within one hour and to maintain this level for at least 72 hours (or until hospital discharge or death if this should occur earlier). A standardised i.v. BP lowering regimen using locally available and approved i.v. BP lowering agents (e.g. Labetalol Hydrochloride, Metoprolol tartrate, Hydralazine Hydrochloride, Glycerol Trinitrate, Phentolamine mesylate, Nicardipine, Urapidil, Esmolol, Clonidine, Enalaprilat, Nitroprusside) will be used, commenced in the emergency department and later in a high dependency area (e.g. acute stroke or neurointensive care unit) as is usual for patients receiving rtPA.
Intensive blood pressure (BP) lowering
Intensive blood pressure (BP) lowering to a target systolic BP range 130-140 mmHg within one hour and to maintain this level for at least 72 hours (or until hospital discharge or death if this should occur earlier). A standardised i.v. BP lowering regimen using locally available and approved i.v. BP lowering agents will be used, commenced in the emergency department and later in a high dependency area (e.g. acute stroke or neurointensive care unit) as is usual for patients receiving rtPA.
The trial is an assessment of BP lowering management strategies, using routinely available drugs. There is some flexibility in the use of particular BP lowering agents to achieve BP targets.
Control / guideline-based BP management
The trial is an assessment of BP lowering management strategies, using routinely available drugs.
Patients allocated to the control group will receive management of BP that is based on a standard guideline, as published by the American Heart Association (AHA). For this group, the attending clinician may consider commencing BP treatment if the systolic level is greater than 180 mmHg, however and the first line treatment will be oral (including nasogastric if required) and/or transdermal routes. Should control of systolic BP not be achieved via these routes, i.v. treatment may be started until the target systolic BP of 180 mmHg is achieved.
BP management policies
Patients allocated to the control group will receive management of BP that is based on a standard guideline, as published by the AHA. For this group, the attending clinician may consider commencing BP treatment if the systolic level is greater than 180 mmHg, however and the first line treatment will be oral (including nasogastric if required) and/or transdermal routes. Should control of systolic BP not be achieved via these routes, i.v. treatment may be started until the target systolic BP of 180 mmHg is achieved.
