A Phase III, Open Label, Randomized, Controlled Study of VBI-S in the Treatment of Hypovolemia in Patients With Septic Shock (VBI-S-02)

PURPOSE OF THE STUDY This study is being conducted to evaluate the safety and effectiveness of VBI-S in elevating the blood pressure of septic shock patients with absolute or relative hypovolemia.

STUDY TREATMENT Sepsis is a serious condition resulting from the presence of harmful microorganisms in the blood or other tissues and the body's response to their presence, leading to the malfunctioning of various organs. When hypotension due to sepsis cannot be reversed with the infusion of fluids the patient is in a state of septic shock. Septic shock is therefore an acute medical emergency and delayed therapy can lead to organ injury. VBI-S is intended to raise blood pressure in patients with septic shock.

Randomization and blinding: This is a randomized, controlled, open-label study and blinding is not applicable to this study.

Data Safety Monitoring Board: A Data Safety Monitoring Board (DSMB) will review the study data.

Inclusion criteria

• Male or female at least 18 years of age.
• Evidence of bacterial infection demonstrated by positive blood culture and/or a known source of infection and/or an elevated procalcitonin of ≥ 2 ng/ml.
• Patient has a mean blood pressure < 65 mmHg that is unresponsive to fluids currently available on the market.
• Sequential Organ Failure Assessment (SOFA) score ≥ 5
• Sepsis diagnosis: The presence of infection which can be proven or suspected by 2 or more of the following criteria:

• Lactate > 2 mmol/L
• Fever > 38.3°C, or 101°F
• Hypothermia < 36°C core temperature (<96.8°F)

• Acute Mesenteric ischemia
• Emergency major surgery
• Diagnosis of acute Hepatitis B or C.
• Hematologic or coagulation disorders including thrombocytopenia (platelet count <50,000) and associated with hemodynamically significant active bleeding that causes a decrease in blood pressure.
