Description

Summary

Prospective, multicenter, randomized, open-label study of standard of care plus the PMX cartridge versus standard of care alone in patients with endotoxemic septic shock

Official Title

A Prospective, Multicenter, Randomized, Open-Label Study to Evaluate the Efficacy and Safety of PMX Cartridge in Addition to Standard Medical Care for Patients With Endotoxemic Septic Shock

Details

This is a prospective, multicenter, randomized, open-label trial of standard medical care plus the PMX cartridge versus standard medical care alone, in subjects with endotoxemia and septic shock. Subjects in critical care areas will be assessed for septic shock using known or suspected infection, multiple organ failure, fluid resuscitation and hypotension requiring vasopressor support as primary criteria. Subjects will meet all entry criteria for study if endotoxin activity is within the range of ≥ 0.60 to <0.90.

Eligible and consented subjects will be randomized to receive either the PMX cartridge (administered twice for 1½ to 2 hours per treatment session approximately 24 hours apart) plus standard medical care or standard medical care alone. For all randomized subjects, a follow-up visit (if they are still in the hospital) or a telephone call will be completed at Day 28 (or later) to determine their mortality status. In surviving subjects, a follow-up visit or telephone call to determine their mortality status will also take place at approximately three months (i.e. Day 90) and 12 months after the subject was randomized.

Eligibility

You can join if…

Open to people ages 18 years and up

  1. Age ≥18 years of age
  2. Hypotension requiring vasopressor support: Requirement for at least one of the vasopressors listed below, at the dose shown below, for at least 2 continuous hours and no more than 30 hours
    1. Norepinephrine > 0.05mcg/kg/min
    2. Dopamine > 10 mcg/kg/min
    3. Phenylephrine > 0.4 mcg/kg/min
    4. Epinephrine > 0.05 mcg/kg/min
    5. Vasopressin > 0.03 units/min
    6. Vasopressin (any dose) in combination with another vasopressor listed above
  3. The subject must have received intravenous fluid resuscitation of a minimum of 30mL/kg administered within 24 hours of eligibility
  4. Documented or suspected infection defined as definitive or empiric intravenous antibiotic administration
  5. The subject must have a screening multi-organ dysfunction score (MODS) >9 OR a sequential organ failure assessment (SOFA) >11, in the event a complete MODS cannot be obtained due to missing measurements
  6. Endotoxin Activity Assay between ≥ 0.60 to <0.90 EA units
  7. Evidence of at least 1 of the following criteria for new onset organ dysfunction that is considered to be due to the acute illness:
    1. Requirement for positive pressure ventilation via an endotracheal tube or tracheostomy tube
    2. Thrombocytopenia defined as acute onset of platelet count <150,000µ/L or a reduction of 50% from prior known levels
    3. Acute oliguria defined as urine output <0.5mL/kg/hr for at least 6 hours despite adequate fluid resuscitation

You CAN'T join if...

  1. Inability to obtain an informed consent from the subject, family member or an authorized surrogate
  2. Lack of commitment for full medical support
  3. Inability to achieve or maintain a minimum mean arterial pressure (MAP) of ≥ 65mmHg despite vasopressor therapy and fluid resuscitation
  4. Subject has end-stage renal disease and requires chronic dialysis
  5. There is clinical support for non-septic shock such as:
    1. Acute pulmonary embolus
    2. Transfusion reaction
    3. Severe congestive heart failure (e.g. NYHA Class IV, ejection fraction < 35%)
  6. Subject has had chest compressions as part of CPR during this hospitalization without immediate return to communicative state
  7. Subject has had an acute myocardial infarction (AMI) within the past 4 weeks
  8. Subject has uncontrolled hemorrhage (acute blood loss requiring > 3 UPC in the past 24 hours)
  9. Major trauma within 36 hours of screening
  10. Subject has severe granulocytopenia (leukocyte count less than 500 cells/mm3) or severe thrombocytopenia (platelet count less than 30,000 cells/mm3)
  11. HIV infection in association with a last known or suspected CD4 count of <50/mm3
  12. Subject's baseline state is non-communicative
  13. Subject has sustained extensive third-degree burns within the past 7 days
  14. Body weight < 35 kg (77 pounds)
  15. Known hypersensitivity to Polymyxin B
  16. Subject has known sensitivity or allergy to heparin or has a history of heparin associated thrombocytopenia (H.I.T.)
  17. Subject is currently enrolled in an investigational drug or device trial
  18. Subject has been previously enrolled in the current trial
  19. Any other condition, that in the opinion of the investigator, would preclude the subject from being a suitable candidate for enrollment, such as end-stage chronic illness (eg. lack of source control and bowel necrosis) with no reasonable expectation of survival to hospital discharge
