About this study
Official title: A Multicenter, Randomized, Double-blind, Placebo-controlled Phase III Clinical Trial to Evaluate the Efficacy and Safety of Edaravone Dexborneol Sequential Therapy in the Treatment of Patients With Acute Ischemic Stroke
SIM0308-302 is a multicenter, randomized, double-blind, placebo-controlled clinical III trial with the primary objective of evaluating the efficacy of Edaravone Dexborneol sequential therapy, consisting of Edaravone Dexborneol Injections followed by Edaravone Dexborneol Sublingual Tablets for total 14 days, in patients with acute ischemic stroke (AIS). The subject has a clinical diagnosis of AIS, within 48 hours from stroke onset to start of study treatment, with a National Institutes of Health Stroke Scale (NIHSS) between 6 and 20, had a total score of upper and lower limbs on motor deficits ≥ 2. The primary outcome is the proportion of subjects with modified Rankin scale score ≤ 2 at 90 days after treatment.

SIM0308-302 is a multicenter, randomized, double-blind, placebo-controlled clinical III trial with the primary objective of evaluating the efficacy of Edaravone Dexborneol sequential therapy, consisting of Edaravone Dexborneol Injections followed by Edaravone Dexborneol Sublingual Tablets for total 14 days, in patients with acute ischemic stroke (AIS). The subject has a clinical diagnosis of AIS, within 48 hours from stroke onset to start of study treatment, with a NIHSS score between 6 and 20, had a total score of upper and lower limbs on motor deficits ≥ 2. The primary outcome is the proportion of subjects with modified Rankin scale score ≤ 1 at 90 days after treatment. The secondary outcomes included mRS score on day 90, the proportion of subjects with mRS score ≤2 on day 90, the change of NIHSS score from baseline to day 14 and the proportion of subjects with NIHSS score ≤1 on day 14, 30, 90 after treatment. Safety outcomes included adverse events, treatment related adverse events within day 90, and changes in vital signs and laboratory data before and after treatment.
Subjects in the Sequential group receive Edaravone Dexborneol concentrated solution for injections 37.5 mg BID administered intravenously for 5 - 10 days, and then followed by Edaravone Dexborneol Sublingual Tablets 30 mg BID administered sublingually for the last days, the total duration of treatment was 14 days. Subjects in the Placebo group receive placebo for 14 days. All the subjects were followed up to day 90 after the treatment.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Edaravone Dexborneol Sequential Therapy in people with Subjects With Acute Ischemic Stroke, run by Simcere Pharmaceutical Co., Ltd.
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 1 inclusion and 1 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 20 Dec 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 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact yi wang, Master (15805160455, wangyi4@simcere.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The proportion of subjects with modified Rankin scale score ≤ 1 on 90 days after treatment (time frame: on 90 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 20 Dec 2023.
