Read the detailed description

This is a multicenter, randomized, double-blind, placebo-controlled, seamless adaptive Phase II/III clinical trial to evaluate the efficacy and safety of Y-6 sublingual tablets in patients with acute perforating artery infarction. The study consists of two stages. In Stage 1, participants will be randomly assigned to receive high-dose Y-6 sublingual tablets (2 tablets, containing a total of 12 mg of borneol and 50 mg of cilostazol), low-dose Y-6 sublingual tablets (1 tablet containing 6 mg of borneol and 25 mg of cilostazol plus 1 matching placebo tablet), or placebo (2 matching placebo tablets), in addition to standard antiplatelet therapy with aspirin (100mg). The purpose of Stage 1 is to evaluate the efficacy and safety of different doses of Y-6 sublingual tablets and select the recommended dose for Stage 2 based on interim analyses reviewed by an independent data monitoring committee (IDMC). In Stage 2, participants will be randomly assigned to receive the selected dose of Y-6 sublingual tablets or placebo, in addition to concomitant aspirin therapy, to confirm the efficacy and safety of Y-6 sublingual tablets. Participants will receive study treatment and be followed for efficacy and safety outcomes, including functional outcomes, adverse events, bleeding events, and other safety assessments

What is being measured

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

  1. Proportion of participants achieving a modified Rankin Scale (mRS) score ≤1 after treatment

    The scale ranges from 0 to 6, where a score of 0 indicates no symptoms and a score of 6 indicates death. Higher mRS scores represent greater disability.

    Measured: Day 90(+7 days)

Secondary outcomes (17)
  1. Distribution of mRS scores after treatment

    The scale ranges from 0 to 6, where a score of 0 indicates no symptoms and a score of 6 indicates death. Higher mRS scores represent greater disability.

    Measured: Day 90(+7 days)

  2. Proportion of participants with stroke-related disability after treatment

    Stroke disability is defined as disability (modified Rankin Scale [mRS] score of 3-5), major adverse cardiovascular events (MACE), including myocardial infarction, stroke, and vascular death, and all-cause mortality.

    Measured: Day90 (+7 days)

  3. Change from baseline in NIHSS (National Institutes of Health Stroke Scale) scores at each assessment time point

    The NIHSS total score ranges from 0 to 42, with higher scores indicating worse neurological outcomes.

    Measured: Day90 (+7 days)

  4. Proportion of participants achieving a Barthel Index score ≥95 after treatment

    The Barthel Index (BI) is a measure of activities of daily living, with scores ranging from 0 to 100. Higher scores indicate greater independence, while lower scores indicate greater dependence on assistance for daily activities.

    Measured: Day 90 (+7 days)

  5. Proportion of participants with early neurological deterioration after treatment

    Early neurological deterioration means within 7 days after stroke attack, an increase in NIHSS of ≥2 points or an increase in hemiparesis of ≥1 point or an increase in impaired consciousness of ≥1 point from baseline and excluding progression of disease due to intracranial hemorrhage by examination of cranial CT or MRI and exacerbation of disease due to other non-stroke causes, such as cardiac insufficiency, hepatic insufficiency, renal insufficiency, etc.

    Measured: 72 hours (±12 hours) after treatment、Day 7 (±1 day)

  6. Proportion of participants with ischemic stroke after treatment

    Measured: Day90 (+7 days)

  7. Incidence of moderate and severe bleeding events after treatment

    Bleeding events will be classified according to the GUSTO bleeding criteria. Severe or life-threatening bleeding is defined as intracerebral hemorrhage or bleeding resulting in substantial hemodynamic compromise requiring treatment. Moderate bleeding is defined as bleeding requiring blood transfusion. Minor bleeding is defined as other bleeding events not requiring transfusion or causing hemodynamic compromise.

    Measured: Day 30 (±3 days)、Day 90 (+7 days)

  8. Incidence of intracranial hemorrhage after treatment

    Measured: Day 30 (±3 days)、Day 90 (+7 days)

  9. Incidence of any bleeding events after treatment

    Measured: Day 30 (±3 days)、Day 90 (+7 days)

  10. All-cause Mortality after treatment

    Measured: Day 30 (±3 days)、Day 90 (+7 days)

  11. Incidence of platelet count ≤100 × 10⁹/L after treatment

    Measured: Day 30 (±3 days)、Day 90(+7 days)

  12. Incidence of new-onset moderate-to-severe headache after treatment

    Headache severity will be assessed using the 11-point Numerical Rating Scale (11-NRS). The scale ranging from 0 to 10, where 0 indicates no headache and 10 indicates the worst imaginable headache. Higher scores indicate greater headache severity.

    Measured: Day 30 (±3 days)、Day 90 (+7 days)

  13. Incidence and severity of adverse events after treatment

    Measured: Day 90 (+7days)

  14. The Incidence of subject getting abnormal results of physical examinations after treatment

    Measured: Day 90 (+7days)

  15. The Incidence of subject getting abnormal results of vital signs after treatment

    Measured: Day 90 (+7days)

  16. The Incidence of subject getting abnormal results of laboratory tests after treatment

    Measured: Day 90 (+7days)

  17. The Incidence of subject getting abnormal results of 12-lead electrocardiograms after treatment

    Measured: Day 90 (+7 days)

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Y-6 tablet in people with Perforating Artery Infarction and PAI, run by Neurodawn Pharmaceutical Co., Ltd. at 1 site 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 10 inclusion and 25 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 23 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined 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.

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 Yilong Wang (13911666571, yilong528@aliyun.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of participants achieving a modified Rankin Scale (mRS) score ≤1 after treatment (time frame: 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 Jul 2026.
