About this study

Official title: Effects of Y-6 Sublingual Tablets for Patients With Acute Ischemic Stroke: A Phase Ⅱ, Randomized, Double-blind, Double-dummy, Placebo-controlled Parallel Trial

Read the detailed description

This study rationale is based on the following scheme: in patients with acute ischemic stroke caused by LVO, receiving reperfusion therapy may cause futile recanalization and thus lead to microcirculation dysfunction and thrombo-inflammation as consequences. Cilostazol has antiplatelet effects and BBB protection and Dexborneol has anti-inflammatory effects; therefore, the multi-component tablet may exert neuroprotective effects in terms of improving microcirculation dysfunction and reducing thrombo-inflammation in patients with AIS after reperfusion therapy.

The primary purpose of this study is to investigate the proportion of modified-Rankin scale (mRS) score recovered to 0~1 score at 90±7 days after randomization.

The follow-up duration is 3 months, and the visit schedule is as follows: Subjects enrolled based on randomization procedures will receive visits at screening/baseline period, 24 ± 2 hours, 7 ± 2 days, 28 + 3 days and 90 ± 7 days after randomization, and in case of any events.

Conditions: Acute Ischemic Stroke, Large Vessel Occlusion, Reperfusion
Being tested: Low-dose Y-6 sublingual tablets, High-dose Y-6 sublingual tablets, Low-dose Cilostazol, High-dose Cilostazol, Placebo
Keywords: Y-6, cilostazol, dexborneol, acute ischemic stroke, large vessel occlusion, reperfusion therapy, FUTURE
Medical subject headings: Ischemic Stroke

What is being measured

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

Proportion of mRS score recovered to 0~1 score
The modified Rankin Scale (mRS) decreasing to 0~1 score. mRS Mainly measures patients' independent living ability, including physical function, activity ability and participation in daily life. A score of 0 on the mRS Scale indicates no symptoms and a score of 5 indicates severe disability.
Measured: At 90±7 days after randomization

Secondary outcomes (4)

The mRS score at 90±7 days after randomization
The modified Rankin Scale (mRS) decreasing to 0~1 score. mRS Mainly measures patients' independent living ability, including physical function, activity ability and participation in daily life. A score of 0 on the mRS Scale indicates no symptoms and a score of 5 indicates severe disability.
Measured: At 90±7 days after randomization
Changes of NIHSS score between baseline and at 24 ± 2 hours, 7 ± 2 days and 28 + 3 days after randomization
NIHSS score after reperfusion therapy within 2 hours changing compared with baseline NIHSS. The NIHSS score ranges from 0 to 42. The higher the score, the more severe the nerve damage.
Measured: At 24 ± 2 hours, 7 ± 2 days and 28 + 3 days after randomization
Proportion of patients with early progression of stroke at 24 ± 2 hours after randomization
Early progression of stroke was defined as: within 7 days after onset, compared to baseline, an increase of ≥ 2 points in NIHSS; or an increase of ≥ 1 point in limb hemiplegia; or an increase of ≥ 1 point in consciousness disorder, excluding those caused by intracranial hemorrhage and other non-stroke causes such as cardiac insufficiency, liver insufficiency, renal insufficiency, etc.
Measured: At 24 ± 2 hours after randomization
Proportion of patients with combined vascular events at 90 ± 7 days after randomization
Combined vascular events were defined as: symptomatic stroke, myocardial infarction and vascular death.
Measured: At 90 ± 7 days after randomization

Primary outcome

Proportion of mRS score recovered to 0~1 score
Time frame: At 90±7 days after randomization
The modified Rankin Scale (mRS) decreasing to 0~1 score. mRS Mainly measures patients' independent living ability, including physical function, activity ability and participation in daily life. A score of 0 on the mRS Scale indicates no symptoms and a score of 5 indicates severe disability.

4 secondary outcomes

The mRS score at 90±7 days after randomization
Time frame: At 90±7 days after randomization
Changes of NIHSS score between baseline and at 24 ± 2 hours, 7 ± 2 days and 28 + 3 days after randomization
Time frame: At 24 ± 2 hours, 7 ± 2 days and 28 + 3 days after randomization
Proportion of patients with early progression of stroke at 24 ± 2 hours after randomization
Time frame: At 24 ± 2 hours after randomization

Questions about this trial

What is this clinical trial studying?

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 8 inclusion and 19 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: status not confirmed, as of the sponsor's last update on 18 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

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 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?

Results are not available in the source record.

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

Contact Yilong Wang, PhD+MD (0086-010-67092222 ext. 0, 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 mRS score recovered to 0~1 score (time frame: At 90±7 days after randomization). 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 NCT06138834, which also lists 16 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 18 Nov 2023.
