A Phase I clinical trial to determine the safety and tolerability of an anti-IL23 antibody for the treatment of patients with alcoholic liver disease

Official Title

A Phase I Clinical Trial to Determine the Safety and Tolerability of Anti-IL23 Monoclonal Antibody, for the Treatment of Patients With Alcohol Associated Liver Disease


This is a phase I study of guselkumab, a humanized anti-IL23 monoclonal antibody, for patients with alcoholic liver disease. This drug is approved for the use in psoriatic arthritis but not for alcoholic liver disease. The investigators will be using a standard 3+3 phase I dose escalation trial design, the dose levels will start from 30 mg, 70 mg and to 100 mg, a maximum total of 24 patients will be evaluable. In this study the investigators propose to establish safety of the product in those with alcoholic liver disease and efficacy (secondary endpoint) will be determined by biomarkers for liver inflammation and fibrosis surrogate biomarkers.

Open to people ages 21 years and up

  1. Able to provide written informed consent (either from patient or patient's legally acceptable representative)
  2. Male or female patients 21 years of age or older with BMI ≥ 20 to ≤ 45 kg/m2
  3. Patients with moderate alcohol use disorder (AUD) as defined by the AASLD Practice

    Guidance to have ≥ 4 symptoms out of 11:

    1. Alcohol is often taken in larger amounts and/or over a longer period than the patient intended.
    2. Persistent attempts or one or more unsuccessful efforts made to cut down or control alcohol use.
    3. A great deal of time is spent in activities necessary to obtain alcohol, use alcohol, or recover from effects.
    4. Craving or strong desire or urge to use alcohol
    5. Recurrent alcohol use resulting in a failure to fulfill major role obligations at work, school, or home.
    6. Continued alcohol use despite having persistent or recurrent social or interpersonal problem caused or exacerbated by the effects of the alcohol.
    7. Important social, occupational or recreational activities given up or reduced because of alcohol use.
    8. Recurrent alcohol use in situations in which it is physically hazardous.
    9. Alcohol use is continued despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by the alcohol.
    10. Tolerance, as defined by either of the following:
    11. Markedly increased amounts of the alcohol in order to achieve intoxication or desired effect
    12. Markedly diminished effect with continued use of the same amount
    13. Withdrawal, as manifested by either of the following:
    14. The characteristic alcohol withdrawal syndrome or
    15. Alcohol (or a closely related substance) is taken to relieve or avoid withdrawal symptoms
  4. Evidence of end-organ damage to the liver as defined by
    1. MRI-PDFF ≥ 8% suggestive of significant hepatic accumulation of triglyceride within 3 months of screening; if patients cannot get an MRI, CAP ≥ 300dB/m
  5. Consumed alcohol within 12 weeks of entry into the study, AND
    1. AST and ALT less than 200 U/L AND
  6. No evidence of active infection as determined by the investigator.
  7. Women of child-bearing potential (defined as females who are not surgically sterile or who are not over the age of 52 and amenorrheic for at least 12 months) must utilize appropriate birth control throughout the study duration. Acceptable methods that may be used are abstinence, birth control pills ("The Pill") or patch, diaphragm, intrauterine device (IUD/ coil), vaginal ring, condom, surgical sterilization or progestin implant or injection, or sexual activity limited to a sterile (e.g., vasectomized) male partner.
  8. Male patients must agree to use a medically acceptable method of contraception/birth control throughout the study duration.

You CAN'T join if...

    7. Acute HCV or chronic hepatitis C with a history of decompensated cirrhosis. (Note: patients with stable chronic Hep C Virus (HCV) or successfully treated HCV are not excluded. Anti-HBc antibody positive patients will be given a prophylaxis with entecavir 0.5mg PO once daily, starting one week prior to start of guselkumab to 6 months after the last dose of guselkumab)
  2. Noninvasive criteria to exclude cirrhosis:
    1. MRE ≥ 3.63 kPa; if MRE not available, VCTE ≥ 16 kPa

  7. Positive Quantiferon test
  8. Significant systemic or major illness other than liver disease, including coronary artery disease, cerebrovascular disease, pulmonary disease, renal failure, serious psychiatric disease, that, in the opinion of the Investigator would preclude the patient from participating in and completing the study
