    The use of obeticholic acid (OCA) was recently approved as second line therapy for patients with primary biliary cholangitis (PBC) with insufficient response or intolerance to ursodeoxycholic acid (UCDA).

    Aim:

    To assess the efficacy and safety of obeticholic acid as second line therapy by patients with PBC (as monotherapy or add-on to UCDA).

    Methods:

    Our study included 28 PBC patients (89.2% women) with a mean age of 61.1 ± 10.1 years from 7 Austrian centers (Klagenfurt, Villach, Salzburg, Linz, Vienna, Eisenstadt and Innsbruck), who received therapy with obeticholic acid because of intolerance or insufficient response under the maximal dose of UCDA (14.2% monotherapy with OCA, 85.8% combination therapy OCA + UCDA). We evaluated the response of alkaline phosphatase (AP), alanine transaminase (ALT), gamma-glutamyltransferase (GGT) and bilirubin under the therapy with OCA. Furthermore, adverse events were assessed.

    Results:

    The median follow up of therapy with OCA was 10.5 months (between 0.5 and 24 months).

    A significant reduction of AP, GGT and ALT was observed under the therapy with obeticholic acid (Table).

    Adverse events were observed in 15/28 (53.5%) of patients. The following adverse events were recorded: pruritus 9/28 (32.1%), fatigue 4/28 (14.2%), joint pain 4/28 (14.2%), abdominal pain 2/28 (7.1%), peripheral edema 1/28 (3.5%), nausea 1/28 (3.5%), exanthem 1/28 (3.5%), and generalized musculoskeletal pain 1/28 (3.5%) of patients.

    The treatment was stopped in 6/28 (21.4%) patients: in one case because of increase of AP and bilirubin after 7 months of therapy and in 5 cases because of adverse events (pruritus -2 cases, severe joint pain and peripheral edema – 1 case, exanthem-1 case and generalized musculoskeletal pain-1 case). One patient was lost from follow-up.

    Conclusion:

    The therapy with obeticholic acid is effective and relatively safe in patients with PBC.
