Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Standard-dose intravenous tenecteplase
Treatment: Drugs - Low-dose intravenous tenecteplase
Other interventions - No intravenous tenecteplase
Other interventions - Conservative Blood Pressure Control
Other interventions - Moderate Blood Pressure Control
Other interventions - Intensive Blood Pressure Control
Other interventions - Placebo
Treatment: Drugs - NoNO-42
Other interventions - No deferoxamine mesylate and no colchicine
Treatment: Drugs - Deferoxamine mesylate only
Treatment: Drugs - Colchicine only
Treatment: Drugs - Both deferoxamine mesylate and colchicine

Experimental: IV thrombolysis domain - This domain has a prospective, randomized, controlled, open-label, parallel group with blinded endpoint assessment (PROBE) design to optimize the use of intravenous Tenecteplase in participants with Acute Ischemic Stroke.

Experimental: Blood Pressure domain - Third Enhanced Control of Hypertension and Thrombectomy Stroke Study (ENCHANTED3/MT) as a domain of ACT-GLOBAL to compare three BP lowering management strategies, that of conservative, moderate and intensive BP lowering in patients with Acute Ischaemic Stroke admitted to participating hospitals who has an elevated SBP after reperfusion therapy via Endovascular Thrombectomy, and reliably determine, which approach leads to improved functional outcome.

Locally available and approved i.v. BP lowering agents can be used in this domain.

Experimental: ACT-42 domain - This domain has a Phase 2b, multicenter, prospective, randomized, open label, blinded-endpoint (PROBE) controlled single-dose adaptive design and aim to determine the efficacy and safety of NoNO-42 in participants with Acute Ischaemic Stroke selected for thrombolysis with or without Endovascular Thrombectomy.

Experimental: INTERACT5 Domain - This is a domain within the Intracerebral Haemorrhage State of the ACT-GLOBAL adaptive platform trial for stroke.

The objective of this domain is to determine the efficacy of intravenous deferoxamine and low-dose oral colchicine, both individually and in combination, compared to standard of care alone, on improving functional outcome in patients with acute spontaneous supratentorial ICH.


Treatment: Drugs: Standard-dose intravenous tenecteplase
Standard-dose intravenous tenecteplase (0.25 mg/kg body weight); one-time IV bolus injection soon after randomisation

Treatment: Drugs: Low-dose intravenous tenecteplase
Low-dose intravenous tenecteplase (0.18 mg/kg body weight); one-time IV bolus injection soon after randomisation

Other interventions: No intravenous tenecteplase
No intravenous tenecteplase only in subjects on direct oral anticoagulant (DOACs) or those planned for emergency endovascular thrombectomy (EVT)

Other interventions: Conservative Blood Pressure Control
No or minimal Systolic Blood Pressure (SBP) control; SBP reduction by 5-10mmHg or a target of 175-180mmHg if very-high baseline SBP (=180mmHg); the timing of administration of interventions is specified to be immediately after randomisation; the intervention target is to be achieved ideally at 1 hour after randomisation and maintained for 24 hours (or until hospital discharge or death if this should occur earlier)

Other interventions: Moderate Blood Pressure Control
SBP reduction by 10-20mmHg or a target of 160 ± 5, whichever is higher; no control if low-high baseline SBP (150-160mmHg); the timing of administration of interventions is specified to be immediately after randomisation; the intervention target is to be achieved ideally at 1 hour after randomisation and maintained for 24 hours (or until hospital discharge or death if this should occur earlier)

Other interventions: Intensive Blood Pressure Control
SBP reduction by 30-50mmHg or a target of 140±5 mmHg, whichever is higher after endovascular thrombectomy (EVT); the timing of administration of interventions is specified to be immediately after randomisation; the intervention target is to be achieved ideally at 1 hour after randomisation and maintained for 24 hours (or until hospital discharge or death if this should occur earlier)

Other interventions: Placebo
100 mL of 0.9% normal saline, administered as a single IV infusion with a 20-minute dosing duration.

Treatment: Drugs: NoNO-42
NoNO-42 at weight-based dosing - 2.6 mg/Kg, administered as a single IV infusion with a 20-minute dosing duration

Other interventions: No deferoxamine mesylate and no colchicine
No deferoxamine mesylate and no colchicine

Treatment: Drugs: Deferoxamine mesylate only
Deferoxamine mesylate at a dose of 32mg/kg/day via intravenous infusion immediately (within 1 hour) and continued for 2 consecutive days

Treatment: Drugs: Colchicine only
0.5mg of oral colchicine daily for 30 days

Treatment: Drugs: Both deferoxamine mesylate and colchicine
Deferoxamine mesylate at a dose of 32mg/kg/day via intravenous infusion immediately (within 1 hour) and continued for 2 consecutive days; plus 0.5mg of oral colchicine daily for 30 consecutive days

Summary
Brief summary
Stroke is causing 6.6 million deaths and is a major cause of disability worldwide in 2019. There remains an urgent need for interventions that improve outcomes which can be implemented with wide applicability for stroke. ACT-GLOBAL is a multi-factorial, multi-arm, multi-stage, randomised, global adaptive platform trial for stroke, aiming to identify the treatment/s associated with the highest chance of improving outcome in stroke patients. In ACT-GLOBAL multiple questions will be evaluated simultaneously and sequentially as data accrues and can evaluate interactions between different treatment options.
