About this study
Official title: Phase II Dose-finding Open Study of Recombinant Human TNK Tissue-type Plasminogen Activator (rhTNK-tPA) Injection Administered Within 3 Hours After Onset of Hyperacute Ischemic Stroke
To explore the safe and efficacious dose of rhTNK-tPA injection administered within 3 hours after onset of hyperacute ischemic stroke; to provide dose evidence for phase III clinical trial.
Read the detailed description
To evaluate the safety and efficacy of rhTNK-tPA at different doses of 0.10 mg/kg, 0.25 mg/kg and 0.32 mg/kg compared with standard rt-PA intravenous thrombolytic therapy within 3 hours after onset of ischemic stroke. The primary objective of this study is to evaluate the differences of NIHSS scores among the four treatment groups at 14 days after intravenous thrombolysis.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing TNK-tPA in people with Acute Ischemic Stroke, run by Beijing Tiantan Hospital at 24 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 24 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
National Institutes of Health Stroke Scale (NIHSS) (time frame: 14 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04676659, which also lists 19 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Dec 2020.
