Polydatin Injectable (HW6) for Shock Treatment

Phase 2

• Conditions: Shock, Hemorrhagic; Shock, Traumatic; Shock, Septic
• Interventions: Drug: Polydatin Injectable

• Registration Number: NCT01780129
• Lead Sponsor: Neptunus Pharmaceuticals Inc.

Brief Summary

HW6 can prolong animal's survival time and increase the survival rate. HW6 enhances cardiac function, improves microcirculation, and increases blood pressure and pulse pressure, and improves blood perfusion of important organs; HW6's anti-shock activity comes from a combined multiple target pharmacological effects.

Based on a completed phase II trial conducted in China, HW6 can effectively treatment shock patient.

This is a phase II clinical study to further evaluate the efficacy and safety of Polydatin Injectable 100mg/5mL/via (HW6) in the treatment of shock in the United States. Patients with traumatic/hemorrhagic shock or septic shock admitted to the emergency room or ICU with systolic blood pressure \< 90mmHg, or is on vasopressor(s) for systolic blood pressure stabilization, regardless the types of completed, on-going, or projected Standard of Care or surgery will be recruited to participant in the trial. A total of 120 patients with traumatic/hemorrhagic shock and 120 patients with septic shock will be enrolled. For each type of shock, sixty patients each will be in test group and control group. Both adult males and females aged 18-80 years are eligible. The primary clinical endpoint is the time length (TL) between the start of HW6 administration to the onset of the first treatment success, that is: the systolic blood pressure is stabilized at ≥90mmHg and MAP≥65mmHg for 1 hour without the use of vasopressors. Several secondary endpoints and biomarkers will be measured.

Efficacy data will be compared using group t-test or Wilcoxon log-rank test between treatment groups and placebo groups. Safety data will also be reported accordingly.

Arm && Interventions

Group	Intervention	Description
Polydatin Injectable (HW6)	Polydatin Injectable	10ml(2 ampoules) diluted in 500ml of 0.9% NaCl solution for i.v. infusion over 2 hours; once daily for 5 consecutive days

Primary Outcome Measures

Name	Time	Method
The time length (TL) between the start of HW6 administration to the onset of the first TS.	From the start of drug administration to the onset of TS (OTS) where the first systolic blood pressure≥90mmHg and MAP≥65mmHg is observed in the 7 consecutive measures	Treatment success (TS): the systolic blood pressure is stabilized at ≥90mmHg and MAP≥65mmHg for 1 hour without the use of vasopressor(s).; Blood pressure will be recorded every 10 min. Treatment success is considered to have been achieved when 7 consecutive systolic blood pressure to be≥90mmHg and MAP≥65mmHg.; The TL is the time from the start of drug administration to the onset of TS (OTS) where the first systolic blood pressure≥90mmHg and MAP≥65mmHg is observed in the 7 consecutive measures.; Blood pressure will be measured every hour after the TS. If blood pressure become unstable, standard care will be in practice.

Secondary Outcome Measures

Name	Time	Method
The amount and duration of total vasopressor(s) used during this TL period	From the start of drug administration to the onset of TS (OTS) where the first systolic blood pressure≥90mmHg and MAP≥65mmHg is observed in the 7 consecutive measures	Observation period: From start of study drug treatment to OTS. Record the details of the use of vasopressor(s) during TL for each subject, including name of medication, infusion concentration and rate, and the duration of each concentration and rate being maintained.; Duration of vasopressor(s) use: accurate to the minute, or by the cumulative time of each administration if used intermittently.; Total dose of vasopressor(s)：The total dose of each vasopressor.
The degree of fluid dependence	from the start of testing drug to the OTS
Metabolic indicators	Within 6 days	Arterial blood lactate, lactate clearance, oxygen saturation mixed venous blood, blood gas levels
Severity of organ dysfunction in the ICU	Daily during the administration stay after enrollment	Compare the changes in SOFA score during the administration stay between the two groups to assess the protective effect of the study drug on vital organs.
Duration of ICU stay	The total time (in hours) of ICU admission from the day of administration to day 7 (7 days)
28-day survival	From the end of drug administration to Day 28
