About this study

Official title: A Multicenter, Randomized, Open-Label, Blinded-Endpoint Trial of Tenecteplase Versus Dual Antiplatelet Therapy in Mild Disabling Ischemic Stroke With Large Vessel Occlusion Beyond 4.5 Hours (TIME-MINOR Trial)

To verify the efficacy and safety of intravenous tenecteplase (TNK) in patients with disabling minor stroke and large vessel occlusion (LVO) within a 4.5-24 hour time window.

Read the detailed description

Stroke is a leading cause of death and disability. Minor stroke (NIHSS ≤5) accounts for 48% of ischemic strokes, with its "mild symptom" presentation masking the potential risk of disability. About 30% of patients have poor 90-day outcomes (mRS ≥2) due to disabling deficits (e.g., unilateral limb weakness ≥2, aphasia, or hemianopia), resulting not only in loss of personal independence but also a surge in family and social medical expenses. Notably, up to 55% of patients present beyond the standard time window (4.5-24 hours). Having missed the golden window for thrombolysis, they are often relegated to conservative treatment. When complicated by large vessel occlusion (LVO), the recanalization rate with dual antiplatelet therapy (DAPT) alone is less than 5%, creating a "silent epidemic" of accumulating disability risk.

The PRISMS trial showed no benefit of thrombolysis within 4.5 hours in non-disabling stroke, but due to the exclusion of the LVO subgroup and early termination (actual enrollment only 313), the potential benefit for disabling patients remains an open question. The TEMPO-2 trial found increased mortality (5% vs 1%) in patients receiving tenecteplase (TNK) without selecting for ischemic penumbra, potentially masking recanalization benefits in certain subgroups (e.g., those with mismatch ratio ≥1.8). A subgroup analysis of TEMPO-2 for onset 4.5-12h, minor disabling stroke (median NIHSS 4), showed a 3-month mRS 0-1 rate of 61.7% in the tenecteplase group vs. 47.2% in the standard care group, but this was not statistically significant due to the small subgroup size. While CHANCE series studies confirmed that DAPT reduces the risk of stroke recurrence by 33%, it is ineffective for LVO recanalization, leaving disability rates high.

The 2023 "Chinese Guidelines for Clinical Management of Cerebrovascular Diseases" and the European Stroke Organisation (ESO) guidelines explicitly state that treatment for disabling minor stroke with LVO beyond the time window (4.5-24 hours) lacks a Class I recommendation (Evidence Level C), leaving clinical decision-making in a dilemma without evidence-based guidance.

DAWN/DEFUSE-3/TRACE Ⅲ studies validated the value of imaging selection in thrombectomy, but they excluded patients with NIHSS ≤5, leaving a gap in penumbra assessment criteria for minor stroke.

Therefore, the investigators designed the TIME-MINOR trial to evaluate whether intravenous tenecteplase, guided by multimodal imaging, can improve outcomes in patients with NIHSS ≤5 and LVO presenting 4.5-24 hours after onset.

A Phase 3 study testing Tenecteplase (0.25mg/kg) and Standard Medical Management in people with Stroke, run by First Hospital of China Medical University at 30 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 7 inclusion and 16 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: opening soon, as of the sponsor's last update on 17 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 30 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 Chuansheng Zhao, M.D (+86 13940369251, cszhao@mail.cmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of patients with a modified Rankin Scale (mRS) score of 0-1 at 90 days. (time frame: 3 months after randomization). 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 17 Mar 2026; AzTrials last refreshed its copy on 30 Oct 2026.
