- Drug: Placebo
- Registration Number
- NCT06176781

- Simcere Pharmaceutical Co., Ltd
- Brief Summary
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.
- Detailed Description
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.
