About

The Children Liver Disease Research and Education Network (ChiLDREN) is conducting a clinical trial to determine the feasibility, acceptability, tolerability and safety profile of IVIG treatment administered to infants after hepatic portoenterostomy (HPE) for biliary atresia, as well as investigate preliminary evidence of activity and explore mechanisms of action.

Full description

In this multicenter prospective phase 1/2A open label trial, the feasibility, tolerability and safety of intravenous immunoglobulin (IVIG) therapy following hepatic portoenterostomy (HPE) will be assessed in 29 infants with biliary atresia (BA), efficacy will be estimated and exploratory mechanistic research studies will be performed. After written consent is obtained from the parent or guardian, the subject will be enrolled and will receive three intravenous doses of IVIG at designated intervals over the first 60 days following HPE and will be followed for 360 days after enrollment. Blood will also be obtained during this study to assess potential mechanisms by which the IVIG may alter or reduce bile duct inflammation and injury and improve bile flow. All infants in this trial will also be treated with standardized doses of other routine standard-of-care treatments for BA during this trial (ursodeoxycholic acid, trimethoprim-sulfamethoxasole, and fat-soluble vitamin supplements). This routine clinical care will not be modified by participation in this study. Subjects in this study will not receive corticosteroid therapy for treatment of biliary atresia, as this is of unproven benefit at the present time.

Inclusion criteria

Infant under 120 days old with established diagnosis of BA. Subjects in this trial must start treatment within 3-5 days of the Kasai procedure and be part of a prospective study of the natural history of biliary atresia also being conducted by ChiLDREN (http://www.clinicaltrials.gov/ct/show/NCT00061828?order=3).
Standard HPE operation has been performed for BA within the previous 3 days
Post-conception age ≥ 36 weeks at time of enrollment
Weight at enrolment ≥ 2000 gm
Written informed consent to participate in the study obtained within 3 days of completion of HPE.

Exclusion criteria

Laparoscopic HPE or "gall bladder Kasai" (cholecysto-portostomy) surgery was performed
Biliary atresia splenic malformation syndrome (presence of asplenia, polysplenia or double spleen)
History of a hypercoagulable disorder
Renal Disease defined as serum creatinine > 1.0 mg/dl prior to enrollment or presence of complex renal anomalies found on imaging
Evidence of congestive heart failure or fluid overload
Presence of significant systemic hypertension for age (defined as persistent systolic blood pressure ≥112 mmHg measured on at least 3 occasions following HPE)
Infants whose mother is known to have human immunodeficiency virus infection
Infants whose mother is known to be serum HBsAg or hepatitis C virus antibody positive
Previous treatment with intravenous immunoglobulin therapy or corticosteroid therapy
Previous treatment with any other investigational agent
History of allergic reaction to any human blood product infusion
Infants with other severe concurrent illnesses, such as neurological, cardiovascular, pulmonary, metabolic, endocrine, and renal disorders, that would interfere with the conduct and results of the study
Any other clinical condition that is a contraindication to the use of IVIG
