Outcome Measures

Primary Outcomes (1)

  • Number of Patients Achieving Necrotizing Infections Clinical Composite Endpoint (NICCE)

    NICCE was made up of the following 5 components, all of which had to be met to successfully achieve the primary outcome measure (i.e., a "responder"): (i) Alive at Day 28, (ii) ≤ 3 debridements through Day 14, (iii) No amputation performed after the first debridement, (iv) Day 14 modified Sequential Organ Failure Assessment (mSOFA) score ≤ 1, and (v) Reduction of ≥ 3 mSOFA score points between Baseline and Day 14. This analysis compared responders in the reltecimod group versus responders in the placebo group. Modified Sequential Organ Failure Assessment (mSOFA) total scores range from 0 to 20, with higher scores reflecting a worse clinical status or outcome. An mSOFA total score of 0 or 1 reflects resolution of organ dysfunction/failure.

Secondary Outcomes (9)

  • Number of Patients With One or More Adverse Events (AEs)

    28 days

  • Number of Patients With One or More Serious Adverse Events (SAEs)

Other Outcomes (10)

    90 days

  • Number of Deaths After Day 14 Through Day 90

    76 days (after Day 14 through Day 90)

  • Number of Deaths From Day 0 Through Day 90 Among Patients With a Screening mSOFA Score of at Least 5

Eligibility Criteria

Age12 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Surgical confirmation of NSTI by attending surgeon;
  • mSOFA score ≥3 (in any one or combination of the 5 major components of SOFA score with one organ component having a score of at least 2: cardiovascular, respiratory, renal, coagulation, CNS), measured as close as possible to the first debridement;
  • IV drug administration within 6 hours from the clinical diagnosis and the decision at the study site, to have an urgent surgical exploration and debridement (drug should not be administered until surgical confirmation is established);
  • If a woman is of childbearing potential, she must consistently use an acceptable method of contraception from baseline through Day 28;
  • If a male patient's sexual partner is of childbearing potential, the male patient must acknowledge that they will consistently use an acceptable method of contraception (defined above) from baseline through Day 28.
  • Signed and dated informed consent (ICF) as defined by the Institutional Review Board (IRB) and, if applicable, California Bill of Rights. If patient is unable to comprehend or sign the ICF, patient's legally acceptable representative may sign the ICF

You may not qualify if:

  • BMI\>51;
  • Patient who has been operated at least once for the current NSTI infection and had a curative deep tissue debridement;
  • Patients with overt peripheral vascular disease in the involved area ;
  • Diabetic patients with peripheral vascular disease who present with below the ankle infection;
  • Patient with burn wounds;
  • Current condition of: (a) Inability to maintain a mean arterial pressure \> 50 mmHg and/or systolic blood pressure \> 70 mmHg for at least 1 hour prior to screening despite the presence of vasopressors and IV fluids or (b) a patient with respiratory failure such that an SaO2 of 80% cannot be achieved or (c) a patient with refractory coagulopathy (INR \>5) or thrombocytopenia (platelet count \<20,000) that does not partially correct with administration of appropriate factors or blood products;
  • Chronic neurological impairment that leads to a neuro mSOFA component ≥2;
  • Recent cerebrovascular accident in the last 3 months;
  • Patients with cardiac arrest requiring cardiopulmonary resuscitation within the past 30 days;
  • Patient is not expected to survive throughout 28 days of study due to underlying medical condition, such as poorly controlled neoplasm;
  • Patient or patient's family are not committed to aggressive management of the patient's condition;
  • Any concurrent medical condition, which in the opinion of the Investigator, may compromise the safety of the patient or the objectives of the study or the patient will not benefit from treatment such as:
  • Congestive heart failure (CHF){ New York Heart Association (NYHA) class III-IV}
  • Severe chronic pulmonary obstructive disease (COPD)
  • Liver dysfunction {Childs-Pugh class C}
  • +11 more criteria
