Study of Seladelpar in Participants With Primary Biliary Cholangitis (PBC)

Korábbi kezelés

• Treatment-related adverse event (AE) leading to study drug discontinuation in a previous PBC study with seladelpar
• Use of colchicine, methotrexate, azathioprine, or long-term use of systemic steroids (eg prednisone, prednisolone, budesonide) (\>2 weeks) within 2 months prior to Screening
• Current use of fibrates or use of fibrates within 3 months prior to Screening
• Current use of obeticholic acid or use of obeticholic acid within 3 months prior to Screening
• Use of an experimental or unapproved treatment for PBC within 3 months prior to Screening
• Treatment with any other investigational therapy or medical device within 30 days or within 5 half-lives, whatever is longer, prior to Screening
• Immunosuppressant therapies (eg, cyclosporine, tacrolimus, anti-TNF or other immunosuppressive biologics)
• Other medications that effect liver or GI functions such as absorption of medications or the roux-en-y gastric bypass procedure may be prohibited and should be discussed with the medical monitor on a case-by-case basis

Más betegség

• A medical condition, other than PBC, that in the Investigator's opinion would preclude full participation in the study or confound its results (eg, cancer, any active infection)
• Auto-immune hepatitis
• Known history of alpha-1-antitrypsin deficiency
• Known history of chronic viral hepatitis
• History of malignancy diagnosed or treated, actively or within 2 years, or active evaluation for malignancy; localized treatment of squamous or non-invasive basal cell skin cancers and cervical carcinoma in-situ is allowed if appropriately treated prior to Screening
• Any other condition(s) that would compromise the safety of the individual or compromise the quality of the clinical study, as judged by the Investigator
• Positive for:
  • Hepatitis B, defined as the presence of hepatitis B surface antigen
  • Hepatitis C, defined as the presence of hepatitis C virus ribonucleic acid (RNA)
  • Human immunodeficiency virus (HIV) antibody
• Active COVID-19 infection during screening
  • Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Laborértékek

• AST or ALT above 3 × the upper limit of normal (ULN)
• Total bilirubin above 2 × ULN
• MELD score ≥ 12. For individuals on anticoagulation medication, evaluation of the baseline INR, in concert with any current dose adjustments in anti-coagulant medications, will be taken into account when calculating this score. This will be done in consultation with the medical monitor.
• Evidence of advanced PBC as defined by the Rotterdam criteria: albumin below 1× the lower limit of normal (LLN) AND total bilirubin above 1 × ULN)
• eGFR ≤45 mL/min/1.73 m2 (calculated by MDRD formula)

Egyéb

• Primary sclerosing cholangitis
• For females, pregnancy or breast-feeding

• Must have given written informed consent (signed and dated)
• Participated in a PBC study with seladelpar
• Females of reproductive potential must use at least one 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
