- Seladelpar Treatment of PBC Patients for Two Years Predicts Improved Transplant-Free Survival
In a poster presentation titled, “Seladelpar Treatment of Patients With Primary Biliary Cholangitis (PBC) For 2 Years Improves the GLOBE PBC Score and Predicts Improved Transplant-Free Survival,”1
Patients with PBC having an incomplete response or intolerance to UDCA (defined as alkaline phosphatase (ALP) ≥ 1.67xULN) had completed an open-label one-year phase 2 study of daily oral seladelpar therapy (NCT: 02955602). After 1 year, patients were eligible for an open label long-term study (NCT: 03301506). Treatment of 50 patients with oral seladelpar 5 mg or 10 mg daily for 2 years resulted in a mean (SD) change from baseline in GLOBE score of -0.417 (0.269), resulting in a corresponding hazard ratio of 0.66 for transplantation or death compared to no prior treatment with seladelpar (baseline). The improvement in GLOBE score and predicted survival did not depend on age. However, an analysis of subpopulations of high risk patients by GLOBE score (> 0.3) revealed that while patients of all ages improved, the younger patients tended to have numerically greater improvements, although these differences did not achieve significance.
“These findings demonstrate that seladelpar treatment over 2 years resulted in a sustained decrease in GLOBE score for patients with PBC. These results provide an estimate of seladelpar’s treatment effect on transplant-free survival for patients with PBC supporting its continued long-term evaluation in patients with PBC,” said Dr.

About PBC
PBC is a rare, chronic inflammatory liver disease primarily affecting women (1 in 1,000) over the age of 40. PBC is characterized by impaired bile flow (known as cholestasis) and the accumulation of toxic bile acids in the liver, leading to inflammation and destruction of the bile ducts within the liver and causing increased levels of alkaline phosphatase (ALP) and total bilirubin. The most common early symptoms of PBC are itching (pruritus) and fatigue, which can be very debilitating for some patients. Progression of PBC is associated with an increased risk of liver cancer and liver-related mortality.
About Seladelpar
Seladelpar is a first-in-class oral, selective PPARδ agonist shown to regulate critical metabolic and liver disease pathways in indications with high unmet medical need. Preclinical and clinical data support its ability to regulate genes involved in bile acids synthesis, inflammation, fibrosis and lipid metabolism, storage and transport.
