Stroke Society Australasia 2012; it begins.

This week is the Stroke Society Australasia Meeting in Sydney incorporating Smart Strokes, IJS will be in attendance keeping you up to date. Andrei Alexandrov will be there speaking on his imaging 'helmet', Val Pomeroy on Neurorehabilitation, Rustam Al-Shahi Salman on mechanisms of intracerebral and subarachnoid haemorrhage, and Christian Stapf whose interests are brain vascular malformations and other conditions predisposing to intracranial haemorrhage. Caroline Watkins will be be talking about stoke service development. Stephanie Ho stroke survivor and Noel Hayman, Queensland Australian of the Year 2011 who works in Indigenous Health.

Last year IJS collected a fabulous series of interviews from SSA.

Protocol for the perfusion and angiography imaging sub- study of the Third International Stroke Trial (IST-3) of alteplase treatment within six hours of acute ischaemic stroke.

Abstract
Rationale: Intravenous thrombolysis with recombinant tissue plasminogen Activator (rt- PA) improves outcomes in patients treated early after stroke but at the risk of causing intracranial haemorrhage. Restricting rt-P A use to patients with evidence of still salvageable tissue, or with definite arterial occlusion, might help reduce risk, increase benefit and identify patients for treatment at late time windows.
Aims: To determine if perfusion or angiographic imaging with CT or MR help identify patients who are more likely to benefit from rt-PA in the context of a large multicentre randomised trial of rt-PA given within six hours of onset of acute ischaemic stroke, the Third International Stroke Trial (IST-3).
Design: IST-3 is a prospective multicentre randomised controlled trial testing rt-PA (0.9mg/kg, maximum dose 90mg) started up to six hours after onset of acute ischaemic stroke, in patients with no clear indication for or contraindication to rt-PA. Brain imaging (CT or MR) was mandatory pre-randomisation to exclude haemorrhage. Scans were read centrally, blinded to treatment and clinical information. In centres where perfusion and/or angiography imaging were used routinely in stroke, these images were also collected centrally, processed and assessed using validated visual scores and computational measures.
Study Outcomes: The primary outcome in IST-3 is alive and independent (Oxford Handicap Score 0-2) at 6 months; secondary outcomes are symptomatic and fatal intracranial haemorrhage, early and late death. The perfusion and angiography study additionally will examine interactions between rt-PA and clinical outcomes, infarct growth and recanalisation in the presence or absence of perfusion lesions and/or arterial occlusion at presentation. The study is registered ISRCTN25765518.

NeuroThera® Efficacy and Safety Trial – 3 (NEST-3): a double-blind, randomized, sham-controlled, parallel group, multicenter, pivotal study to assess the safety and efficacy of transcranial laser therapy with the NeuroThera® Laser System for the treatment of acute ischemic stroke within 24 h of stroke onset

Rationale Transcranial laser therapy is undergoing clinical
trials in patients with acute ischemic stroke. The NeuroThera
® Efficacy and Safety Trial-1 was strongly positive for
90-day functional benefit with transcranial laser therapy,
and post hoc analyses of the subsequent NeuroThera® Efficacy
and Safety Trial-2 trial suggested a meaningful beneficial
effect in patients with moderate to moderately severe
ischemic stroke within 24 h of onset. These served as the
basis for the NeuroThera® Efficacy and Safety Trial-3 randomized
controlled trial.
Aim The purpose of this pivotal study was to demonstrate
safety and efficacy of transcranial laser therapy with the
NeuroThera® Laser System in the treatment of subjects diagnosed
with acute ischemic stroke.
Design NeuroThera® Efficacy and Safety Trial-1-3 is a
double-blind, randomized, sham-controlled, parallel group,
multicenter, pivotal study that will enroll 1000 subjects at up
to 50 sites. All subjects will receive standard medical management
based on the American Stroke Association and
European Stroke Organization Guidelines. In addition to
standard medical management, both groups will undergo
transcranial laser therapy procedure between 4·5 and 24 h of
stroke onset. The study population will be randomized into
two arms: the sham control group will receive a sham transcranial
laser therapy procedure and the transcranial laser
therapy group will receive an active transcranial laser
therapy procedure. The randomization ratio will be 1:1 and
will be stratified to ensure a balanced subject distribution
between study arms.
Study Outcomes The primary efficacy end point is disability
at 90 days (or the last rating), as assessed on the modified
Rankin Scale, dichotomized as a success (a score of 0–2) or a
failure (a score of 3 to 6).
