Real-world experience with odevixibat in children with progressive familial intrahepatic cholestasis

Abstract: Background & aims: A previously published trial demonstrated that odevixibat is effective in the treatment of cholestatic pruritus of children with progressive familial intrahepatic cholestasis (PFIC). Real-world experience is necessary to confirm the results of registration trials with selective eligibility criteria. We present our 'real-life experience' of the effectiveness and safety of odevixibat in patients with different PFIC subtypes. Methods: We carried out a multicenter prospective study of patients with PFIC treated with odevixibat (40 or escalated to 120 μg/kg/day). Pruritus was assessed by 'Physician Global Impression of Symptom' at baseline and monthly up to 6 months. Serum bile acids (sBA) responders were patients who achieved a reduction in sBA levels ≥70% from baseline (or a value <70 μmol/L) after 6 months; pruritus responders were patients who reported improvement in their pruritus score. Results: <0.001). No serious adverse events were recorded. Conclusions: Odevixibat is effective and safe in reducing sBA levels and improving pruritus in a real-life scenario in both patients with classic PFIC types and in those with other rarer subtypes. Dose escalation is required in some patients to improve the response to treatment. Impact and implications: Published data on the use of odevixibat in a real-world scenario are lacking. We explored the effectiveness of odevixibat in a heterogenous cohort of children diagnosed with PFIC (including patients with classic as well as rarer types of PFIC, and with advanced liver disease and associated comorbidities). Our results demonstrate that odevixibat is effective for the treatment of cholestasis and pruritus in children with different PFIC subtypes in a real-life scenario. These results support the use of odevixibat in children with any type of PFICs, including those with different stages of liver disease and comorbidities.
