Clinical Trial Summary

This clinical trial was planned for the purpose to re-evaluate the safety and efficacy of naloxone hydrochloride in ischemic cerebral nerve disorders caused by stroke and cerebral hemorrhage.

Eligible subjects will be randomized to the naloxone hydrochloride group or placebo group at 1:1 ratio.

Also, factors, such as disease subtype and severity, which might impact the efficacy endpoints will be used to stratify.

• Stratification factor: cerebral infarction (NIHSS 5-15 points or 16-20 points) or cerebral hemorrhage

Administration of investigational product should be started within 48 hours from the onset of symptoms.

Subject receive the investigational product 7 consecutive times (for 7 days) in a single dose of intravenous infusion for 24 hours.

• Patients who have passed more than 48 hours since the onset of symptoms.

• Subjects who received other therapeutic investigational product within the last 30 days.

• Patients who transient ischemic attack.

• Patients whose life expectancy is less than 3 months due to comorbidities other than stroke

• Thrombolysis (including non-drug treatments such as thrombolytic drugs and mechanical procedures used in thrombolysis) or extraventricular drainage (surgical treatment) has been performed or is scheduled to be performed.

• Thrombolytic agent used in thrombolysis[ex. Streptokinase, Alteplase, Anistreplase, Urokinase, Reteplase, Tenecteplase, Tissue-plasminogen activator (t-PA), Single-chain urokinase-type plasminogen activator (Scu-PA), Lanoteplase, Monteplase, Plasminogen activator inhibitors (PAI)]

• Surgical treatment [ex. mechanical thrombectomy, external ventricular drainage (EVD), extralesional drainage (ELD), decompression], Subarachnoid hemorrhage (SH), Trauma patients [ex. SH coiling, traumatic intracranial hemorrhage (ICH)], Among patients with infarction, patients who need or are scheduled to perform Depressive craniomy.

• Any condition that, in the opinion of the investigator, would inappropriate to participate in the clinical trial

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of subjects who have the modified Rankin Scale (mRS) score of 2 or less on Day 90	Modified Rankin Scale is an index that evaluates the patient's global functional outcome according to the independence of daily life and the degree of need for help from others. It is evaluated in seven stages (0 to 6 points), from asymptomatic to death. The higher score means a worse outcome, and 3 to 6 points are considered to be poor functional outcome.	Day 90
Secondary	The change from baseline in Modified Rankin Score (mRS) up to Day 90	Modified Rankin Scale is an index that evaluates the patient's global functional outcome according to the independence of daily life and the degree of need for help from others. It is evaluated in seven stages (0 to 6 points), from asymptomatic to death. The higher score means a worse outcome, and 3 to 6 points are considered to be poor functional outcome.	Baseline, Day 3, Day 7, Day 14(or discharge), Day 30 and Day 90
Secondary	The change from baseline in Modified Barthel Index (mBI) up to Day 90.		Baseline, Day 3, Day 7, Day 14(or discharge), Day 30 and Day 90
Secondary	The change from baseline in EuroQol five dimensions questionnaire(EQ-5D) up to Day 90		Baseline, Day 3, Day 7, Day 14(or discharge), Day 30 and Day 90
Secondary	The change from baseline in Korean Mini-Mental State Examination(KMMSE) up to Day 90		Baseline, Day 3, Day 7, Day 14(or discharge), Day 30 and Day 90
Secondary	The change from baseline in Global Deterioration Scale (GDS) up to Day 90	The GDS is a staging scale indicating deterioration in dementia, The scale details clinical descriptions of seven major distinguishable stages, ranging from normal cognition to severe dementia.; Stages 1 - 3 are the pre dementia stages. Stages 4 -7 reflect the stages of dementia. People beginning with stage 5 are no longer survive without assistance.	Baseline, Day 3, Day 7, Day 14(or discharge), Day 30 and Day 90
Secondary	The change from baseline in National institutes of health stroke scale(NIHSS) up to Day 90	It will be evaluated in patients with cerebral infarction.; The NIHSS is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke.; The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4.; For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment.; The individual scores from each item are summed in order to calculate a patient's total NIHSS score.; The maximum possible score is 42, with the minimum score being a 0.	Baseline, Day 3, Day 7, Day 14(or discharge), Day 30 and Day 90
Secondary	The change from baseline in Glasgow Coma Scale(GCS) up to Day 90	It will be evaluated in patients with cerebral hemorrhage. The Glasgow Coma Scale (GCS) is used to objectively describe the extent of impaired consciousness in all types of acute medical and trauma patients.; The Glasgow Coma Scale divides into three parameters: best eye response (E), best verbal response (V) and best motor response (M). The levels of response in the components of the Glasgow Coma Scale are 'scored' from 1, for no response, up to normal values of 4 (Eye-opening response) 5 ( Verbal response) and 6 (Motor response) The total Coma Score thus has values between three and 15, three being the worst and 15 being the highest.	Baseline, Day 3, Day 7, Day 14(or discharge), Day 30 and Day 90
Secondary	The odds ratio of the factors which contribute to a mRS score to be less than or equal to 2 on Day 90	The factors, such as sex, age, disease subtype and severity, investigational product compliance, which might impact the mRS score to be less than or equal to 2 will be analyzed.	Day 90
