Trial Outcomes & Findings for SITS-IVT in Patients >80 Years Study (NCT NCT04260347)

NCT ID: NCT04260347

Last Updated: 2024-07-05

Results Overview

Defined as the number of participants presenting intracerebral haemorrhage (parenchymatous haemorrhage type 2, PH2), at the 22-36 hours post-treatment scan or earlier, if clinically indicated, combined with neurological deterioration leading to an increase of 4 points on the National Institutes of Health Stroke Scale (NIHSS) from baseline to 24h or death within 24 hours (SITS-MOST definition). The NIHSS is a neurological examination tool used to objectively quantify stroke severity. It is composed by 11 items, 3 of which with more than one component, scoring between 0 (normal function) and 2, 3, 7 or 8 (highest degree of impairment) for a specific ability (item). The sum of the individual scores from each item originate the total NIHSS score, where: 0 = no stroke symptoms; 1-4 = minor stroke; 5-15 = moderate stroke; 16-20 = moderate to severe stroke; and 21-42 = severe stroke.

Participant Flow

Observational retrospective study based on existing data collected from the Safe Implementation of Treatment in Stroke-International Stroke Treatment Registry (SITS-ISTR) of ischaemic stroke patients older than 80 years of age treated with Actilyse® (alteplase) according to the Summary of Product Characteristics (SmPC) criteria during post-approval and pre-approval periods.

The patients were selected based on the sites fulfilling the criteria defined and treated according to the Summary of Product Characteristics (SmPC) of Actilyse® (alteplase) during pre-approval and post-approval period. The data was collected between June 2015 and December 2021. A patient was excluded from the entire cohort when had missing data on one of the selection steps.

Actilyse® (Alteplase) Pre-approval
Patients older than 80 years presenting acute ischaemic stroke symptoms, between June 2015 and July 2018 (or the exact approval date), received once intravenous thrombolysis treatment with off-label Actilyse® (alteplase) within 4.5 hours after stroke onset, according to the Summary of Product Characteristics (SmPC). The recommended total dose was 0.9 milligrams (mg) alteplase per kilogram body weight (maximum of 90 mg) starting with 10% of the total dose as an initial intravenous bolus, immediately followed by the remainder of the total dose infused intravenously over 60 minutes.
Actilyse® (Alteplase) Post-approval
Patients older than 80 years old presenting acute ischaemic stroke symptoms, between 1st July 2018 (or the first day of the next month after exact approval date) to December 2021, received once intravenous thrombolysis treatment with Actilyse® (alteplase) within 4.5 hours after stroke onset, according to the Summary of Product Characteristics (SmPC). The recommended total dose was 0.9 milligrams (mg) alteplase per kilogram body weight (maximum of 90 mg) starting with 10% of the total dose as an initial intravenous bolus, immediately followed by the remainder of the total dose infused intravenously over 60 minutes.
