Brief Summary:
Multicentre, open, randomised, and controlled trial conducted in patients diagnosed with acute on chronic liver failure (ACLF) who meet inclusion/exclusion criteria.The objective of GRAFT-trial is to evaluate efficacy and safety of subcutaneously administered granulocyte colony-stimulating factor (G-CSF) in patients with ACLF. All patients will receive standard medical care for ACLF according to the guidelines. Patients in the experimental arm additional receive subcutaneous injections of G-CSF.

Condition or disease Intervention/treatment
Acute-On-Chronic Liver Failure Drug: G-CSF Other: Standard therapy

Detailed Description:
The acute on chronic liver failure (ACLF) is characterised by a severe deterioration of liver function due to a precipitating event on top of an underlying chronic liver disease. As therapeutic options are limited the mortality rate lies between 40 and 80% at 3 months. The granulocyte colony-stimulating factor (G-CSF) mobilized stem- as well as immune cells and improved liver function in preclinical trials. G-CSF treatment reduced the rate of infectious complications and significantly improved patients´ survival in acute on chronic liver failure, shown recently in small randomised studies. Thus, G-CSF is a promising treatment option that needs to be evaluated in a multi-centre controlled trial. The GRAFT trial will randomise patients with ACLF between standard of care with and without G-CSF. All participants will be followed for 12 months in order to evaluate safety and efficacy of G-CSF. If successful, the GRAFT trial has the potential to change clinical practice in acute on chronic liver failure.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Acute-on-chronic liver failure (ACLF) according to the consensus criteria recently defined by the CANONIC study group [Moreau 2013]. Patients with acute decompensation of cirrhosis [defined as acute development of one or more of the following: ascites (onset and/or worsening), hepatic encephalopathy (onset and/or worsening), gastrointestinal haemorrhage, bacterial infection] are classified as ACLF if one of the following applies:

    • single kidney failure (serum creatinine level ≥ 2 mg/dl) or
    • single failure of one of the following organ systems: liver, coagulation, circulation, or respiration, together with a serum creatinine level ranging from 1.5 to < 2.0 mg/dl and/or mild to moderate hepatic encephalopathy or
    • single cerebral failure together with serum creatinine level ranging from 1.5 to < 2.0 mg/dl or
    • two or more organ failures. Organ failures are defined according to the CLIF-C OFs [Jalan 2014].
  2. Age ≥ 18 years, male or female
  3. Written informed consent from patient, legal or authorized representative or a confirmation of justification of trial participation by an independent medical consultant PLEASE NOTE: In case of confirmation by the independent medical consultant a deferred informed consent from patient, legal or authorized representative has to be given

Exclusion Criteria:

  1. Prior not curatively treated or active malignancies
  2. Sickle cell disease
  3. Septic shock as defined by ACCP/SCCM consensus [Bone 1992]
  4. WBC-count of > 50 x 109/L
  5. Known HIV infection
  6. Known intolerance to filgrastim
  7. Suspected lack of compliance
  8. Pregnant or nursing women
  9. Fertile women (within two years of their last menstruation) without appropriate contraceptive measures (implanon, injections, oral contraceptives, intrauterine devices, partner with vasectomy) while participating in the trial (participants using a hormone-based method have to be informed of possible effects from the trial medication on contraception).
  10. Participation in other interventional trials
