2026년 11월 5일 업데이트: The George Institute

뇌졸중에 대한 다요인, 다군, 다단계, 무작위, 글로벌 적응형 플랫폼 시험(ACT-GLOBAL)

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.

상세 설명

Stroke is the second leading cause of death, worldwide. It is also the second largest cause of disability-adjusted-life-years (DALYs) lost after ischaemic heart disease in developing countries, and third largest contributor to DALYs in developed countries (after ischaemic heart disease, low back and neck pain). In 2019, the absolute numbers of new strokes (12.2 million), stroke-related deaths (6.6 million), and people living with stroke (101.5 million) had increased globally from 1990 (70%, 43%, and 85% increases, respectively).

Steady progress has been made in establishing specific management strategies for patients affected by, or at high-risk of, stroke. Unfortunately, only a few acute treatments have been proven to be beneficial: thrombolysis, endovascular thrombectomy, hemicraniectomy, stroke unit care, and aspirin. There is a continued need for interventions that improve outcomes which can be implemented with wide applicability for stroke.

ACT-GLOBAL is an investigator-initiated, multi-factorial, multi-arm, multi-stage, randomised, global adaptive platform trial for stroke, aiming to find the treatment/s associated with the highest chance of improving outcome after stroke. In ACT-GLOBAL multiple questions will be evaluated simultaneously and sequentially as data accrues and can evaluate interactions between different treatment options.

Frequent adaptive analyses are conducted to assess whether a given intervention is superior, inferior, or equivalent either within a domain or for specific populations within the domain. Where it is anticipated that interactions between interventions in different domains may be likely, the statistical models will allow evaluation of such interactions. Each intervention within a domain with prospectively defined and mutually exclusive strata (sub-groups) of participants will be evaluated within the strata, while information from one stratum may be used (via 'borrowing') to contribute to the analysis of the effect of that intervention in other strata. Specific interventions or subgroups within overall populations may be dropped or cease to enrol, based on pre-specified rules.

The adaptive design allows new interventions or domains or both to be introduced. A Response Adaptive Randomisation algorithm may be used to preferentially randomize participants to interventions that appear to be performing better in domains where applicable.

Unlike traditional trial designs which explicitly prohibit co-enrollment of patients into different trials or multiple therapies, or use a factorial design, the adaptive platform design allows investigators to replicate the real-world environment to estimate possible synergy, competitive interference, or safety profiles of complex treatment protocols.

The ACT-GLOBAL platform is organized into four states defined by stroke type, treatment phase, or therapeutic purpose: Acute Ischemic Stroke (AIS), Intracerebral Hemorrhage (ICH), Secondary Prevention, and Rehabilitation. AIS and ICH are acute stroke-type states, whereas Secondary Prevention and Rehabilitation are therapeutic-purpose states that can span stroke types. Eligibility is assessed hierarchically at platform, state, and domain levels. State subprotocols provide the clinical framework, and domain-specific appendices define additional eligibility criteria, intervention comparisons, procedures, outcomes, follow-up, and analysis requirements.

The AIS State includes patients with a clinical diagnosis of acute ischemic stroke; the ICH State requires confirmation of intracerebral hemorrhage by brain imaging. Core functional outcome assessments use the modified Rankin scale at 90 days in AIS and at 6 months in ICH, with domain-specific requirements specified in the relevant appendices.

The Secondary Prevention State addresses prevention of recurrent stroke and other vascular events after stroke or transient ischemic attack. The index event must have been clinically assessed and the participant sufficiently stable for the relevant intervention. Domains may evaluate antithrombotic, blood pressure, lipid or metabolic, cardiac-monitoring, vascular or procedural, adherence, lifestyle, or service-delivery strategies. Each domain prospectively specifies its own primary outcome and follow-up schedule; the state does not mandate a single universal primary outcome.

The Rehabilitation State includes medically stable adults with stroke who have a rehabilitation need or a personally meaningful goal relevant to an active domain. Domains may evaluate therapy timing or dose, mobility, upper-limb function, activities of daily living, cognition, communication, swallowing, mood or fatigue, technology or telerehabilitation, care transitions, or service delivery. Each domain prespecifies an appropriate primary outcome and assessment time. For broad pragmatic or service-delivery domains, the preferred default is the Barthel Index or a validated activities-of-daily-living measure at 6 months; targeted domains use a construct-valid target-specific outcome. Domain availability and intervention eligibility are determined by the relevant protocol and participating site. Additional states and domains may be introduced through platform governance and applicable approvals.

CoPRIME is a planned phase 2a safety and feasibility domain within the Secondary Prevention State. Under the updated CoPRIME protocol (DAPT062026, version 1.0, 18 September 2026), 300 eligible adults with non-cardioembolic acute ischemic stroke treated with intravenous thrombolysis and/or endovascular thrombectomy will be randomized 1:1:1 to aspirin alone, aspirin plus clopidogrel, or aspirin plus ticagrelor for 21 days, with follow-up to 90 days. As of 5 November 2026, the updated protocol has been submitted to Health Canada and has not yet enrolled participants. NCT07844603 remains the CoPRIME registration; enrolment under the earlier protocol is distinct from enrolment under the updated protocol.

실험적: IA Thrombolysis Domain

This domain will be conducted as part of ACT-GLOBAL platform trial and will have the nested domain name of REACT. This domain aims to efficiently, reliably, and simultaneously, determine the effectiveness of targeted intraarterial (IA) thrombolysis using either tenecteplase or alteplase vs. no IA thrombolysis in all patients who undergo EVT. It has a prospective, randomised, controlled, open-label, parallel group with blinded endpoint assessment (PROBE) design of up to 1,500 subjects with AIS who undergo EVT.

Randomisation will be stratified by country/ region, and the IA thrombolytic agent (tenecteplase or alteplase). Minimal sufficient balance algorithm will operate within each stratum to preserve balance on key covariates while maintaining allocation randomness.

The duration of follow-up is 90 days. Primary outcome will be mRS, conducted through centralized telephone interviews or online media performed by central trial personnel blinded treatment assignment and received.

Participants randomised to the IA thrombolysis group will receive IA thrombolysis (tenecteplase or alteplase) at the time of completion of the mechanical thrombectomy part of the EVT procedure. Tenecteplase will be given at a dose of 0.0625mg/kg (maximum dose of 6.25mg) and alteplase at a dose of 0.225 mg/kg (maximum dose 22.5mg) intraarterially by the treating neuro-interventional staff. The selection of thrombolytic agent will be determined according to local availability.

The study drug dose will be increased to 0.125 mg/ kg (maximum dose 12.5mg) for tenecteplase or 0.45 mg/kg (maximum dose 40mg) for alteplase if above dose meet prespecified posterior probabilities at the first or second interims per adaptive design report.

Participants randomised to the No IA thrombolysis group will not receive IA thrombolysis.

실험적: IMP-ACT domain

This is a randomized, open-label, blinded-endpoint, phase 3 domain within the Acute Ischemic Stroke State. Up to 800 adults with stroke due to medium-vessel occlusion are randomized to usual care, mechanical endovascular thrombectomy (EVT) without intra-arterial (IA) thrombolysis, or mechanical EVT followed by adjunctive IA thrombolysis with tenecteplase or alteplase. Usual medical and stroke-unit care is provided in all groups; intravenous thrombolysis may be given when eligible. Participants are followed for 90 days. Treatment details are specified in the IMP-ACT domain registration (NCT07906275).

Usual medical and stroke-unit care, including intravenous thrombolysis when eligible. This is the usual-care strategy in IMP-ACT (NCT07906275), without assigned mechanical endovascular thrombectomy or adjunctive intra-arterial thrombolysis.

Mechanical endovascular thrombectomy (EVT) using tools and techniques selected by the treating neurointerventionalist. This procedure is used in both EVT strategies in IMP-ACT (NCT07906275); the EVT-alone strategy does not include intra-arterial thrombolysis.

Adjunctive intra-arterial tenecteplase or alteplase delivered by microcatheter into the affected arterial territory following mechanical endovascular thrombectomy. The agent is selected according to local availability. This intervention is used only in the EVT-plus-intra-arterial-thrombolysis strategy. Regimen details are specified in the IMP-ACT domain registration (NCT07906275).

실험적: CoPRIME domain

CoPRIME is a planned phase 2a, multicentre, randomized, open-label, blinded-endpoint safety and feasibility domain within the Secondary Prevention State of ACT-GLOBAL. It will enrol 300 eligible adults with non-cardioembolic acute ischemic stroke treated with intravenous thrombolysis and/or endovascular thrombectomy. Eligible participants are randomized 1:1:1 within 30 hours after the end of acute reperfusion therapy, after a post-reperfusion non-contrast CT and with NIHSS <=10 at randomization, to aspirin alone, aspirin plus clopidogrel, or aspirin plus ticagrelor for 21 days. Study treatment starts within 60 minutes of randomization, and participants are followed for 90 days. As of 5 November 2026, the updated protocol has been submitted to Health Canada; the domain remains in the planning phase, with no enrolment under the updated protocol. Domain registration: NCT07844603.

Aspirin 160 mg on day 1, followed by 81 mg once daily on days 2-21. Study treatment starts within 60 minutes of randomization. This is the aspirin-alone strategy in CoPRIME.

Aspirin 160 mg plus clopidogrel 300 mg on day 1, followed by aspirin 81 mg once daily plus clopidogrel 75 mg once daily on days 2-21. Study treatment starts within 60 minutes of randomization. This is the aspirin-plus-clopidogrel strategy in CoPRIME.

Aspirin 160 mg plus ticagrelor 180 mg on day 1, followed by aspirin 81 mg once daily plus ticagrelor 90 mg twice daily on days 2-21. Study treatment starts within 60 minutes of randomization. This is the aspirin-plus-ticagrelor strategy in CoPRIME.

modified Rankin scale (mRS) scores
기간: Platform level time frame: 90 days in Ischaemic Stroke State; 6 months in Intracerebral Haemorrhage State; Domain specific time frame may differ (details will be included in domain-specific registration)

The mRS is a 7-outcome ordered categorical scale that assesses functional neurological status after stroke. It is not intended for use as a measure of historical functional status. It is well accepted as a standard outcome around the world in the stroke community, by patients and by regulatory authorities. The seven values and the clinical summary of the individual scores are summarized in the following:

0 = No symptoms

  1. = No significant disability; able to carry out all usual activities
  2. = Slight disability; can look after own affairs, but unable to carry out all previous activities
  3. = Moderate disability; require some help
  4. = Moderately severe disability; unable to attend to own bodily needs without assistance
  5. = Severe disability; bedridden and requiring constant nursing care and attention
  6. = Dead
