E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
The condition to be treated is the stroke of “minor” grade (National Institutes of Health Stroke Scale (NIHSS) score < 5). |
La condizione medica oggetto di studio è l’ictus minore (punteggio alla scala NIHSS <5). |
|
E.1.1.1 | Medical condition in easily understood language |
A stroke is the rapid loss of brain function(s) due to ischemia, a disturbance in the blood supply to the brain caused by blood vessel thrombosis. |
L’ictus consiste in una rapida perdita di funzioni cerebrali dovuta ad ischemia, un disturbo nell’apporto di sangue al cervello causato da trombosi di un vaso sanguigno. |

E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
to demonstrate the reduction in disability (mRS at 90 days: 0-1) in treated patients with “minor” stroke (NIHSS <5 at the time of the decision to treat).
to demonstrate the safety of rt-PA in minor stroke, investigating overall mortality at day 90, any hemorrhage, symptomatic or not at day 90.
|
dimostrare la riduzione della disabilità (mRS a 90 giorni: 0-1) nei pazienti trattati con “minor” stroke (NIHSS <5 al momento della decisione a trattare).
Dimostrare la sicurezza dello rtPA negli ictus minori, valutando la mortalità e le complicanze emorragiche sintomatiche ed asintomatiche a 90 giorni.
|
|
E.2.2 | Secondary objectives of the trial |
The secondary objective of the trial is to make a contribution to the empirical European Guidelines for rt-PA treatment which currently recommend treating only patients with an NIHSS score between 5 and 24. |
In caso di risultati positivi, con questo studio ci si propone anche di contribuire a rafforzare l’affermazione finale dell’IST-3 che sostiene non esistano criteri di gravità per l’esclusione dei pazienti dal trattamento, e a modificare le raccomandazioni delle linee guida Europee ed Italiane dell’ictus, che raccomandano il trattamento con rtPA per NIHSS tra 5 e 24. |

• blood glucose level lesser than 50 mg per deciliter or greater than 400 mg per deciliter;

• emorragia intracranica alla TC
• tempo d’ esordio non conosciuto
• ictus moderati o severi con NIHSS > 5
• ASPECT score alla TC >7
• crisi epilettiche all’esordio dello ictus, con impossibilità d’ utilizzare PI-TC o RM PI-DWI. Le crisi epilettiche non sono criterio d’esclusione se viene dimostrata l’ischemia mediante le tecniche di mismatch.
• ictus o grave trauma cranico nei precedenti 3 mesi
• somministrazione di eparina nelle 48 ore precedenti l’ictus, con aumento del tempo parziale della tromboplastina al di sopra dei limiti di norma al momento della valutazione
• numero di piastrine inferiore a 100.000/mmc
• pressione arteriosa sistolica maggiore di 185 e diastolica superiore a 110, non correggibili con opportuna terapia
• livello ematico del glucosio inferiore a 50 mg/dl o superiore a 400 mg/dl;
• sintomatologia suggestiva per emorragia subaracnoidea, anche in presenza di TC negativa;
• trattamento anticoagulante orale con INR > 1,4;
• trattamenti chirurgici maggiori o trauma grave nei 3 mesi precedenti
• altri disordini maggiori associati ad un aumentato rischio di sanguinamento
