About

An open-label, multi-center, prospective, randomized study to evaluate the efficacy, safety and tolerability of LCP-Tacro tablets given once daily vs. azathioprine, each in combination with prednisone, for the treatment of autoimmune hepatitis (AIH).

Full description

An open-label, multi-center, prospective, randomized study to evaluate the efficacy, safety and tolerability of LCP-Tacro tablets given once daily vs. azathioprine for the treatment of autoimmune hepatitis (AIH).

Patients with histologically confirmed chronic hepatitis who fulfill criteria established by the International Autoimmune Hepatitis Group (IAIHG) and Inclusion and Exclusion criteria will be enrolled after having signed an informed consent document.

Up to 60 patients will be randomized (1:1) to receive treatment with LCP-Tacro + prednisone vs. azathioprine (AZA) + prednisone.

  • LCP-Tacro will be started at 2 mg once daily (q.d.) with weekly measurement of tacrolimus whole blood trough levels and adjustment of the daily dose of LCP-Tacro to achieve target tacrolimus levels of 3 - 6 ng/mL. Patients with histological evidence of cirrhosis and a Model for End-Stage Liver Disease (MELD) score ≤ 8 will commence LCP-Tacro at a fixed dose of 1 mg once daily, with subsequent dosage adjustments to maintain tacrolimus trough levels at 3 - 6 ng/mL.
  • AZA will be started at 50 - 100 mg (approximately 1 mg/kg) once daily (q.d.).

Patients will also commence treatment with prednisone 30 mg/day for one week, then 20 mg/day for one week, then 15 mg/day for two weeks, then 10 mg/day through Month 6.

  • Patients with alpha-fetoprotein ≥ 20 ng/mL
  • Patients with severe anemia (hemoglobin < 8 g/dL), leukopenia (WBC < 4000/mm3), or thrombocytopenia (platelet count < 100,000/mm3)
  • Patients with a history of recent exposure to hepatotoxic drugs
  • Patients who require therapy with any immunosuppressive agent other than those prescribed in the study
  • Patients unable or unwilling to provide informed consent
  • Pregnant or nursing women
  • Patients with reproductive potential who are unwilling/unable to use a double barrier method of contraception
  • Patients who have been treated with another investigational agent in the three months prior to enrollment

  • Patients with current malignancy or a history of malignancy (within the past 5 years), except basal or non-metastatic squamous cell carcinoma of the skin that has been treated successfully
  • Patients with uncontrolled concomitant infection, a systemic infection requiring treatment, or any other unstable medical condition that could interfere with the study objectives
  • Patients with severe diarrhea, vomiting, active peptic ulcer or gastrointestinal disorder that may affect the absorption of tacrolimus
  • Patients with a known hypersensitivity to azathioprine, corticosteroids or tacrolimus
  • Patients with any form of current substance abuse, psychiatric disorder or a condition that, in the opinion of the Investigator, may invalidate communication with the Investigator
  • Patients who are recipients of an organ transplant or who require treatment with immunosuppressives or corticosteroids for any disease other than AIH.
