Alteplase use safe in stroke patients above 80 years also: Study

A recent study has found that Alteplase has a positive benefit-risk profile among elderly patients. The study was published in the journal, "Stroke" 2020.

Expert guidelines specify no upper age limit for alteplase for thrombolysis of acute ischemic stroke (AIS) but, until recently, European regulatory criteria restricted its use to patients aged 18 to 80 years. 

Intravenous Alteplase is a recombinant tissue-type plasminogen activator prescribed for thrombolytic treatment of acute ischemic stroke (AIS). It is generally administered in 3-4.5hrs after the onset of symptoms of stroke in various areas as the regulatory approval differs in different areas. Recently regulatory criteria have restricted its use to patients aged 18-80yrs.

Researchers from Germany and United Kingdom conducted pooled analyses of the randomized controlled trial (RCT) and registry data to evaluate the benefit-risk profile of alteplase for Acute ischaemic stroke among patients aged >80 years to support a regulatory application and to lift the upper age restriction.

The authors evaluated individual patient data from 7 randomized trials of alteplase (0.9 mg/kg) versus placebo or open control for acute ischaemic stroke, and the European SITS-UTMOST registry database. They evaluated patients who met the existing European regulatory criteria for alteplase, excluding upper age restriction. Clinical outcomes, including good functional outcome (score 0–1, modified Rankin Scale day 90 or Oxford Handicap Score day 180), were evaluated in the full RCT and registry populations, and specified age-based subgroups (≤80 or >80 years).
