Trial Outcomes & Findings for TNK-tPA Evaluation for Minor Ischemic Stroke With Proven Occlusion (NCT NCT01654445)

NCT ID: NCT01654445

Last Updated: 2020-11-25

Results Overview

The primary safety outcome will be the rate of expected serious adverse events associated with study drug. This will be defined as the number patients with at least one SAE divided by the number of patients enrolled by dose-tier. Thus, the unit of analysis will be the patient and not the SAE.

SECONDARY outcome

Timeframe: 90 days

Population: All enrolled participants

Complete neurological and functional recovery at 90 days defined as: NIHSS 0 and mRS 0 iii)Complete neurological and functional recovery at 90 days defined as: a. NIHSS 0-1 and mRS 0-1 and Barthel Index \> 90 NIHSS = National Institutes of Health Stroke Scale. This integer scale ranges 0-42 and is a quantitative measure of the neurological examination. mRS = modified Rankin Scale. This integer scale ranges from 0-6 and is a criterion-based quantitative measure of functional neurological disability. BI = Barthel Index. This scale range from 0-100 (in increments of 5 points) and is a summative categorical score measuring activities of daily living.
