Condition/Disease

Primary Biliary Cholangitis

Objectives

主要目標 療效:評估 seladelpar 相較於安慰劑對無事件存活期 (EFS) 的影響。EFS 定義為從治療開始到第 156 週首次出現以下任何經裁定事件所經過的時間: •因任何原因死亡 •肝臟移植 •末期肝病模型 (MELD) 評分≥15 •需要治療的腹水 •因發生以下任何符合條件的事件而住院: o食道或胃靜脈曲張出血 o肝性腦病變(定義為 West Haven 評分 ≥2) o透過診斷性腹腔穿刺術,依據白血球 (WBC) 計數、分類、和/或嗜氧和/或厭氧血液培養瓶生長呈陽性,確認為自發性細菌性腹膜炎 安全性:評估 seladelpar 在 156 週治療期間相較於安慰劑的安全性 次要目標: 評估 seladelpar 對以下項目的影響: •整體存活期 •無肝臟移植存活期 (LTFS),定義為從開始治療到首次發生肝臟相關死亡或肝臟移植所經過的時間 •因以下任何符合條件的經裁定事件而住院發生前經過的時間: o食道或胃靜脈曲張出血 o肝性腦病變或 o自發性細菌性腹膜炎 •其他各項經裁定 PBC 臨床事件發生前經過的時間(MELD 評分≥ 15 以及需要治療的腹水) 探索性目標: 評估疾病和 seladelpar 對個別經裁定 PBC 臨床事件發生前經過時間、疾病和肝損傷的肝臟生化標記、肝臟組織學、肝臟硬度、疾病和/或惡化生物標記、藥物動力學 (PK)、患者自述生活品質指標、PBC 預後標準和搔癢的影響。

2.評估治療引發不良事件 (TEAE);生物化學和血液學實驗室評估

Inclution Criteria

Inclusion Criteria:

Individuals must meet the following criteria to be eligible for study participation:

Must be at least 18 years old.
Must have a confirmed prior diagnosis of PBC
Evidence of cirrhosis
CP Score A or B
Females of reproductive potential must use at least 1 barrier contraceptive and a second effective birth control method during the study and for at least 90 days after the last dose. Male individuals who are sexually active with female partners of reproductive potential must use barrier contraception, and their female partners must use a second effective birth control method during the study and for at least 90 days after the last dose
Individuals must be able to comply with the instructions for study drug administration and be able to complete the study schedule of assessments (SOA)

Exclusion Criteria

Exclusion Criteria:

Individuals must not meet any of the following criteria to be eligible for study participation:

Prior exposure to seladelpar
A medical condition other than PBC that, in the Investigator's opinion, would preclude full participation in the study
History of liver transplantation or actively listed for cadaveric or planned living donor transplant.
Decompensated cirrhosis
Evidence of portal vein thrombosis based on imaging at time of Screening by Doppler ultrasound or prior evidence by CT or MRI
Hospitalization for liver-related complication within 12 weeks of Screening
Laboratory parameters at Screening:

Alkaline phosphatase (ALP) < 1.5× Upper limit of normal (ULN) or ≥ 10×ULN
Alanine aminotransferase (ALT) or Aspartate aminotransferase (AST) ≥5×ULN
Total bilirubin (TB) ≤ 0.6 × ULN or ≥ 5 × ULN
