About this study

Official title: Efficacy and Safety of Low-Dose Tenecteplase for Acute Ischemic Stroke Treatment in Aging Patients: A Prospective, Multicenter, Randomized Controlled Study

The DATE-AGING study is a prospective, multicenter, randomized controlled trial investigating low-dose tenecteplase in elderly patients with acute ischemic stroke. Its primary objective is to evaluate the safety and efficacy of low-dose tenecteplase in elderly patients within 4.5 hours of acute ischemic stroke onset.

Being tested
low-dose tenecteplase intravenous thrombolysis, standard-dose tenecteplase intravenous thrombolysis

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • low-dose tenecteplase intravenous thrombolysisDrug

    Subjects will be randomized to low-dose group or standard-dose group in a 1:1 ratio. Patients in the low-dose group received tenecteplase (0.175 mg/kg) for intravenous thrombolysis. The upper dose limit is set to 17.5 mg/patient.

  • standard-dose tenecteplase intravenous thrombolysisDrug

    Subjects will be randomized to low-dose group or standard-dose group in a 1:1 ratio. Patients in the standard-dose group received tenecteplase (0.25 mg/kg) for intravenous thrombolysis. The upper dose limit is set to 25 mg/patient.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With Modified Rankin Scale (mRS) Score of 0 or 1

    Modified Rankin Scale (mRS) is a standardized measure that describes the extent of disability after a stroke. The mRS is a single item scale. It increases from 0 (no symptoms at all) to 6 (death).

    Measured: At Day 90±7 days

Secondary outcomes (8)
  1. Percentage of participants with major neurological improvement (National Institutes of Health Stroke Scale (NIHSS) score of 0 or improvement of at least 4 points compared with baseline)

    National Institutes of Health Stroke Scale (NIHSS) is a 11-item neurologic examination stroke scale used to evaluate the effect of acute cerebral infarction on the levels of consciousness, language, neglect, visual-field loss, extraocular movement, motor strength, ataxia, dysarthria, and sensory loss. A trained observer rates the patent's ability to answer questions and perform activities. Ratings for each item are scored with 3 to 6 grades with 0 as normal, and there is an allowance for untestable items.Total NIHSS score (0-42) = sum of 11 individual item scores, higher total scores meaning more severe deficits.

    Measured: At 24 hours

  2. Percentage of Participants With Modified Rankin Scale (mRS) Score of 0-2

    Modified Rankin Scale (mRS) is a standardized measure that describes the extent of disability after a stroke. The mRS is a single item scale. It increases from 0 (no symptoms at all) to 6 (death).

    Measured: At Day 90±7 days

  3. Distribution of Modified Rankin Scale (mRS)

    Modified Rankin Scale (mRS) is a standardized measure that describes the extent of disability after a stroke. The mRS is a single item scale. It increases from 0 (no symptoms at all) to 6 (death).

    Measured: At Day 90±7 days

  4. Percentage of Participants With Barthel Index Score ≥95

    The Barthel Index is an ordinal scale used to measure performance in activities of daily living (ADL). The Barthel Index consists of 10 items. The total score of the Barthel Index ranges from 0 to 100, and higher scores indicate better outcome.

    Measured: up to 90 days

  5. EQ-5D-5L score

    Health-related quality of life (the score on the EuroQol Group 5-Dimension 5-Level [EQ-5D-5L] questionnaire, range, -0.39 to 1, with higher scores indicating better quality of life)

    Measured: At Day 90±7 days

  6. Percentage of Participants With Symptomatic Intracerebral Haemorrhage (sICH)

    sICH via criteria adapted from the European Cooperative Acute Stroke Study (ECASS III), defined as any apparent extravascular blood in the brain or within the cranium that is associated with clinical deterioration defined by an NIHSS score increase of four points or more from baseline.

    Measured: up to 36 hours

  7. All-cause mortality

    All-cause mortality at 90 days

    Measured: up to 90 days

  8. Percentage of Participants With Modified Rankin Scale (mRS) Score of 5 or 6

    Modified Rankin Scale (mRS) is a standardized measure that describes the extent of disability after a stroke. The mRS is a single item scale. It increases from 0 (no symptoms at all) to 6 (death).

    Measured: At Day 90±7 days

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing low-dose tenecteplase intravenous thrombolysis and standard-dose tenecteplase intravenous thrombolysis in people with Acute Ischemic Stroke Patients, run by Southwest Hospital, China at 51 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 20 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: looking for participants now, as of the sponsor's last update on 23 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 51 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Hou Xianhua (86-13594020663, houxianhua@tmmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants With Modified Rankin Scale (mRS) Score of 0 or 1 (time frame: At Day 90±7 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 23 Jun 2026.
