TReatment for ImmUne Mediated PathopHysiology

Summary

TReatment for ImmUne Mediated PathopHysiology (TRIUMPH) is a multi-center, three arm, randomized, controlled trial of immunosuppressive therapy for children with acute liver failure. The study will determine if suppressing inflammatory responses with either corticosteroids or equine anti-thymocyte globulin therapy improves survival for children with this rare, life-threatening condition.

Eligibility

Inclusion Criteria:

1. Patient with liver injury of ≤ 6 weeks duration resulting in an international normalization ratio (INR) of ≥ 1.5 or \< 2.0 (not corrected by vitamin K) with evidence of hepatic encephalopathy (HE), INR of ≥ 1.5 or \< 2.0 for at least 7 days duration without evidence of HE or INR ≥ 2.0 without evidence of HE.
2. Age is greater than or equal to 1 year and less than 18 years of age.
3. Patient or their legally authorized representative(s) (LAR) must consent (and assent, if applicable) to be in the study and must have signed and dated an approved informed consent form which conforms to federal and institutional guidelines.
4. Females of reproductive potential should not plan on conceiving children during the study and must agree to use a medically accepted form of contraception.

Exclusion Criteria:

1. Evidence of active infection with Hepatitis A, B, C, E or evidence of acute herpes simplex virus (HSV) or adenovirus infection
2. Travel within the past 3 months to an area highly endemic for Hepatitis E
3. Diagnosis of hemophagocytic lymphohistiocytosis (HLH) Note: Patients with a history of consanguinity and/or central nervous system (CNS) dysfunction that is exaggerated compared to the degree of liver dysfunction (as judged by the site investigator) will not be enrolled until results of rapid genetic testing are available. Turn-around time for genetic testing results is estimated to be 72-96 hours.
4. Aplastic anemia as defined by standardized criteria \[1\] diagnosed prior to enrollment
5. Diagnosis of autoimmune Hepatitis (AIH)
6. Diagnosis of acute Wilson disease
7. Diagnosis of inborn error of metabolism Note: Suspicion of metabolic disease is not an exclusion for entry into the Trial.
8. Diagnosis of acute drug or toxin-induced liver injury
9. History of recreational drug use within the past 4 weeks
10. Therapy with an immunosuppressive agent, including chemotherapy, biological therapies or an experimental drug or device within the past 6 weeks
11. Liver injury due to ischemia
12. Liver dysfunction diagnosed more than 6 weeks prior to screening
13. History of allergy to horse dander
14. Sepsis
15. Imminent risk of death as judged by the clinical site investigator, including but not limited to; signs of cerebral herniation at the time of enrollment and presence of intractable arterial hypotension
16. Solid organ or stem cell transplant recipient
17. Pregnant or breast-feeding at the time of proposed study entry
18. Clinical AIDS or HIV positive
19. History of any form of malignant neoplasm and/or tumors treated within five years prior to study entry (other than non-melanoma skin cancer or in situ cervical cancer) or where there is current evidence of recurrent or metastatic disease
20. Received a live-virus vaccine within 4 weeks of study entry
21. Patients with positive respiratory secretion testing for respiratory viral infection including SARS-CoV-2, influenza and respiratory syncytial virus only if they also have declining respiratory function
22. Psychiatric or addictive disorders that would preclude obtaining informed consent/assent
23. Patient is unwilling or unable to adhere with study requirements and procedures
24. Currently receiving other experimental therapies
