Information source: The George Institute
ClinicalTrials.gov processed this data on August 23, 2015
Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Intracerebral Hemorrhage; Stroke; Hypertension

Intervention: Blood pressure management policies (Other)

Phase: N/A

Status: Completed

Sponsored by: The George Institute

Official(s) and/or principal investigator(s):
Craig Anderson, PhD, Principal Investigator, Affiliation: The George Institute

Summary

The purpose of this academic lead study is to determine if a treatment strategy of early intensive blood pressure (BP) lowering compared to conservative BP lowering policy in patients with elevated blood pressure within 6 hours of acute intracerebral haemorrhage (ICH) improves the outcome of death and disability at 3 months after onset.

Clinical Details

Official title: An International Randomised Controlled Trial to Establish the Effects of Early Intensive Blood Pressure Lowering in Patients With Intracerebral Haemorrhage.

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: A Composite of Death or Dependency, With Dependency Being Defined by a Score of 3 to 5 on the Modified Rankin Scale (mRS)

Secondary outcome: Death at 90 Days

Detailed description: Intracerebral haemorrhage (ICH) is one of the most serious subtypes of stroke, affecting over a million people worldwide each year, most of whom live in Asia. About one third of people with ICH die early after onset and the majority of survivors are left with major long-term disability. Despite the magnitude of the disease burden and cost on healthcare resources, there remains uncertainty about the role of surgery for ICH and no acute medical therapies have been shown to definitely alter outcome in ICH. The INTERACT2 study follows the recently completed initial pilot study vanguard phase) which established the feasibility of the protocol, safety of early intensive BP lowering, and effects on haematoma expansion within 6 hours of onset of ICH. Having established 'proof-of-concept' that BP lowering may improve outcome by reducing haematoma expansion, INTERACT2 aims to establish the effects of the treatment on major clinical endpoints in patients with ICH recruited from an expanding clinical network around the world.

Eligibility

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Patients with CT-confirmed spontaneous Intracerebral Haemorrhage (ICH)

- Elevated systolic blood pressure (>150mmHg and <220mmHg)

- Capacity to commence randomly assigned treatment within 6 hours of onset of ICH.

- Able to be 'actively' treated and admitted to a monitored facility

Exclusion Criteria:

- Clear indication or contraindication to intensive BP lowering.

- Evidence ICH secondary to a structural abnormality

- Use of thrombolytic agent

- Previous ischaemic stroke within 30 days

- A very high likelihood that the patient will die within the next 24 hours on the

basis of clinical and/or radiological criteria

- Score of 3-5 on the Glasgow Coma Scale (indicating deep coma)

- Significant pre-stroke disability or advanced dementia

- Planned early neurological intervention

- Participation in another clinical trial.

- A high likelihood that the patient will not adhere to the study treatment and

follow-up regimen.
