About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age ≥ 70 years;

Diagnosis of ischaemic stroke with a measurable neurological deficit on National Institutes of Health Stroke Scale (NIHSS) (1≤ NIHSS ≤25); if NIHSS <4, patients have to be with at least a measurable deficit on motor power (upper or lower limbs ≥1);

Stroke symptoms should have been present for at least 30 minutes (min) without significant improvement prior to randomisation;

Thrombolytic therapy can be initiated within 4.5 Hour(s) (h) of Acute ischaemic stroke (AIS) onset;

Disqualifiers

Imaging demonstrates multi-lobar infarction (hypodensity >1/3 cerebral hemisphere);

Acute bleeding diathesis or allergy to tenecteplase, including but not limited to

Known genetic predisposition to bleeding or significant bleeding disorder at present or within the past 6 Month(s) (m)

Administration of heparin within the previous 48 h and activated partial thromboplastin time (aPTT) exceeding the upper limit of normal for laboratory measurement

Trial design

Design model

Parallel

Treatments tested in this trial

  • low-dose tenecteplase intravenous thrombolysis

    Drug

    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 thrombolysis

    Drug

    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.

Trial outcomes

Primary outcomes

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).

Time frame
At Day 90±7 days

Secondary outcomes

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.

Time frame
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).

Time frame
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).

Time frame
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.

Time frame
up to 90 days
