Primary Outcome Measures:

Percent of patients that achieve biochemical remission of (AIH) at Month 6 during treatment with LCP-Tacro + prednisone or azathioprine + prednisone. Biochemical remission is defined as ALT, total bilirubin and gamma globulin within normal limits. [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Percent of patients who achieve biochemical remission by Month 3 during treatment with LCP-Tacro + prednisone or azathioprine + prednisone. [ Time Frame: 3 months ] [ Designated as safety issue: No ]
Percents of patients in each treatment group classified as either in remission, having an incomplete response, a treatment failure, or a case of relapse. Each patient will be classified as being one of the four states at Month 6. [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Estimated Enrollment:	60
Study Start Date:	December 2007
Study Completion Date:	July 2009
Primary Completion Date:	February 2009 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: LCP-Tacro LCP-Tacro tablets(1,2,and 5mg tacrolimus)+ prednisone tablets(5mg)	Drug: LCP-Tacro (tacrolimus) LCP-Tacro(tacrolimus)tablets starting at 2 mg once daily, then adjusted to achieve and maintain target whole blood tacrolimus levels of 3 - 6 ng/mL, plus 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. Other Name: 1,2,and 5mg tacrolimus tablets
Active Comparator: Azathioprine Azathioprine tablets(50mg)+ prednisone tablets(5mg)	Drug: Azathioprine Azathioprine tablets 50 - 100 mg (approximately 1 mg/kg) once daily, plus 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. Other Name: 50mg azathioprine tablets + 5mg prednisone tablets

Detailed 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.
