Phase II AutoImmune Hepatitis
- Registration Number
- NCT03593460
- Lead Sponsor
- Christopher O'Brien, MD
- Brief Summary
This is a Phase IIa open label adaptive design dose finding study in male and female patients with autoimmune hepatitis (AIH) with compensated liver function currently under standard of care. The purpose of this study is to evaluate the sPIF dose that normalizes and maintains the serum ALT when given for 14 doses.
Autoimmune Hepatitis is disease where the patient's immune system produces an inappropriate immune response against their own liver. PreImplantation factor (PIF) is a substance that is secreted by viable fetuses during pregnancy. PIF initiates both maternal tolerance preventing the loss/rejection of the fetus. Synthetic PIF (sPIF) successfully translates PIF endogenous properties to pregnant and non-pregnant immune disorders. sPIF was found to be effective in preclinical models of autoimmunity and transplantation. Specifically, sPIF protected the liver against immune attack.
- Detailed Description
The study is an open label, dose finding trial in patients with AIH who have an elevated ALT levels. Patients will be administered a starting dose of sPIF 1mg/kg (n=10/cohort) for 14 days assessing safety, tolerability and clinical response based on the effect on ALT levels until day 84. This will be followed by enrolling (n=10) patients administering 2mg/kg sPIF for 14 days assessing safety, tolerability and clinical response based on the effect on ALT levels until day 84. This be followed by an interim analysis that will determine clinical efficacy by comparing the 1mg and 2mg dose results; testing the decrease in mean ALT percent and determining the number of patients in remission defined as normalized ALT level. The successful cohort will enroll additional patients to enable power analysis. If no significant improvement is observed in the two cohorts, N=10 patients will be enrolled and administered 3mg/kg sPIF for 14 days assessing safety and tolerability. If no significant improvement is noted and safety and tolerability is maintained additional 10 patients will be enrolled at 4mg/kg. Following the same analysis, the maximal dose to be administered will be 5mg/kg.

Group Intervention Description sPIF 1 mg/kg (Starting Dose) Synthetic PreImplantation Factor Patients will be administered a starting dose of sPIF 1mg/kg (n=10/cohort) for 14 days assessing safety, tolerability and clinical response based on the effect on ALT levels sPIF 4 mg/kg Synthetic PreImplantation Factor Patients will be administered a starting dose of sPIF 4mg/kg (n=10/cohort) for 14 days assessing safety, tolerability and clinical response based on the effect on ALT levels sPIF 5 mg/kg Synthetic PreImplantation Factor Patients will be administered a starting dose of sPIF 5mg/kg (n=10/cohort) for 14 days assessing safety, tolerability and clinical response based on the effect on ALT levels. sPIF 2 mg/kg Synthetic PreImplantation Factor Patients will be dosed at 2mg/kg sPIF for 14 days assessing safety, tolerability and clinical response based on the effect on ALT levels. sPIF 3 mg/kg Synthetic PreImplantation Factor Patients will be administered a starting dose of sPIF 3mg/kg (n=10/cohort) for 14 days assessing safety, tolerability and clinical response based on the effect on ALT levels
- Primary Outcome Measures
Name Time Method Evaluate the safety and tolerability of multiple ascending, subcutaneously administered doses of sPIF in patients with autoimmune hepatitis (AIH) by measuring changes in ALT 12 weeks Change of ALT from baseline to normal range
Evaluate the pharmacokinetics of sPIF levels in the circulation after multiple ascending, subcutaneously administered doses of sPIF by normalization of liver enzymes, immunoglobulins, and bilirubin levels 12 weeks normalized AST, ALP, GGT, IgG, and bilirubin levels
Evaluate the safety and tolerability of the increased sPIF dose and treatment duration by no SAEes greater than grade 3 12 weeks No SAE \> Grade 3 observed
