Inclusion criteria
-
Chronic liver disease, defined as cirrhosis with ascites based on clinical findings (biopsy not necessary).
-
Subjects with either Type 1 or Type 2 HRS defined in a and b below:
a. Type 1: i. At least a doubling of the serum creatinine to a minimum of 220 µmol/L (2.5 mg/dL) at enrollment, occurring over a period of less than 14 days, OR ii. A 50% or greater reduction in the estimated glomerular filtration rate (GFR - calculated by the method of Cockcroft-Gault) to below 20 mL/min at enrollment occurring over a period of less than 14 days.
iii. A projected doubling of serum creatinine to a minimum of 2.5 mg/dL, expected to occur in less than 14 days based on the rate of change observed.
b. Type 2: defined as at least a 33% reduction in creatinine clearance occurring over a period of greater than 2 weeks, with a serum creatinine (SCr) > 133µmol/L (1.5 mg/dL).
-
Oliguria occurring within 48 hours prior to the first administration CTM. Oliguria is defined as an average urine output of < 35 mL/hr (measured for a minimum of 4 hours) under either of the following circumstances:
a. When measured central venous pressure (CVP) > 12 mmHg, OR b. following a fluid challenge consisting of either: i. at minimum 20 mL/kg isotonic fluid (e.g. any combination of 5% albumin, normal saline, blood or blood products) given over no more than 6 hours ii. at minimum 1 g/kg of hypertonic fluid (e.g. 25% albumin) given over no more than 24 hours iii. an equivalent combination of 3.b.i and 3.b.ii

- Burns > 30% body surface area
- Exposed to investigational drugs within 30 days before 1st CTM administration.
- Inability to understand the requirements of the study. (Subjects must be willing to provide written informed consent or consent of legally recognized representative, as evidenced by signature on an informed consent document approved by an Institutional Review Board [IRB], and agree to abide by the study restrictions. If the subject is incapacitated, informed consent will be sought from a legally recognized representative).
- Refusal to provide written authorization for use and disclosure of protected health information.
- Be otherwise unsuitable for the study, in the opinion of the Investigator.
