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.

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 an open label study, randomization and blinding are not applicable to this study. All patients entering this study will be treated with VBI-S.

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

Analysis Populations: * Safety Analysis Set (SAF): all patients who have received any amount of VBI-S. * Intent to treat (ITT) population: all patients who have received any amount of VBI-S

Inclusion criteria:

1. Male or female at least 18 years of age

2. Evidence of bacterial infection demonstrated by positive blood culture and/or a known source of infection or an elevated procalcitonin of ≥ 2 ng/ml.

3. Patient has a mean blood pressure < 65 mmHg that is unresponsive to fluids currently available on the market.

4. Sequential Organ Failure Assessment (SOFA) score >= 5.

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
   • Mottled skin
   • Decreased capillary refill of nail beds or skin

   • Elevated procalcitonin in serum (≥ 2 ng/ml)
   • Arterial hypoxemia (PaO2/FiO2 < 300)
   • Acute drop in urine output (<0.5 ml/kg/hr for at least 2 hours despite fluid resuscitation, or about 30 ml/hour for a 70 kg person)
   • Creatinine increase > 0.5 mg/dL
