Detailed Description

A multi-center, randomized, double-blind, parallel, placebo-controlled trial design was adopted, and subjects were randomly assigned to Y-3 for injection group and placebo group in a 1:1 ratio. randomization stratification factors include: onset time (≤12 hours, >12 hours) and research site.

Treatment was continued for 10 days (10 times), and follow-up was conducted until the 90th day from the first dose.

The trial is divided into three phases: screening/baseline phase, treatment phase, and follow-up phase.

Screening/baseline period: After the subjects sign the informed consent form, they enter the screening/baseline period for screening examination.

Treatment period: Qualified subjects are randomly divided into groups in a 1:1 ratio and receive continuous treatment for 10 days (10 times) with Y-3 for injection and placebo respectively. During the treatment period, relevant examinations and evaluations required by the protocol will be carried out; PK blood samples from subjects were collected for population pharmacokinetic analysis.

Follow-up period: Subjects who have completed treatment will enter the follow-up period until the 90th day of treatment.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Y-3 for injection test group
The special solvent Y-3 for injection was extracted with a sterile syringe and injected into a Y-3 lyophilized powder vial for injection. The vial was artificially vibrated until the powder was completely dissolved, and then injected into 250mL 0.9% sodium chloride injection with a sterile syringe for dilution, gently shaken and mixed, and intravenous infusion was performed for 60min±10min. The treatment was performed 10 times for 10 days. The first dose should be completed as soon as possible after randomization; The time from the second dose to the first dose shall not be less than 12h, but not more than 24h+1h. The time interval of each subsequent administration is 24h±1h
Drug: Y-3 for injection
Qualified subjects were randomly divided into groups in a 1:1 ratio and received continuous treatment with Y-3 injection (40 mg/dose, qd) or placebo control drug. The treatment was performed 10 times for 10 days.
Placebo Comparator: Placebo control group
The special solvent Y-3 for injection was extracted with a sterile syringe and injected into the lyophilized powder vial of Y-3 simulant for injection. The vial was artificially vibrated until the powder was completely dissolved, and then injected into 250mL 0.9% sodium chloride injection with a sterile syringe for dilution, gently shaken and mixed, and intravenous infusion was performed for 60min±10min.

Measure the scores of subjects using the National Institute of Health stroke scale(NIHSS). Measure on the 10th and 30th day of treatment to evaluate the effectiveness of the medication.National Institute of Health stroke scale(NIHSS) A larger difference from baseline means a better patient recovery, and a smaller difference means a worse patient recovery.
