Brief Summary:
This is a Phase 2a, multi-center, placebo-controlled study in which patients with autoimmune hepatitis will receive zetomipzomib or placebo in addition to standard-of-care for 24 weeks; an optional open-label extension period allows patients to receive zetomipzomib (KZR-616) for an additional 24 weeks of treatment.
Detailed Description:
This is a Phase 2a, multi-center, randomized, double-blind, placebo-controlled study with an open-label extension to evaluate safety, tolerability, and efficacy of zetomipzomib in patients with autoimmune hepatitis (AIH) who have not benefited from standard-of-care treatment, had an incomplete response to ≥3 months of standard-of-care treatment, or had a disease flare after standard of care.
Zetomipzomib or placebo will be administered weekly for a 24-week treatment period in addition to standard-of-care (glucocorticoids), followed by a 4-week off-treatment safety follow-up period. Zetomipzomib and placebo will be administered subcutaneously (SC) once weekly.
At the end of the 24-week treatment period, eligible patients from both the zetomipzomib- and placebo-treated arms who complete the double-blind treatment period can enroll in the open-label extension period to receive an additional 24 weeks of treatment with zetomipzomib.
Primary completion date represents the anticipated completion date of the double-blind portion of the study. Study completion date represents the anticipated completion date of the open-label extension portion of the study.
