Pharmacokinetics of TNO155 in Participants With Mild, Moderate, or Severe Hepatic Impairment Compared to Matched Healthy Participants

This is an interventional diagnostic trial for Hepatic Impairment focused on measuring Hepatic, Impairment, TNO155, Phase 1, pharmacokinetics, safety, Tolerability, Child-Pug Read More

Inclusion Criteria:

All participants Participants must weigh at least 50 kg and no more than 120 kg and must have a body mass index (BMI) within the range of 18.0 to 38.0 kg/m2, inclusive, for healthy participants. For participants with hepatic impairment without overt ascites, the BMI should be within the range of 18.0 to 40.0 kg/m2. For participants with hepatic impairment with overt ascites, the BMI should be within the range of 18.0 to 45.0 kg/m2.

Group 1

•Each healthy control participant must match in age (± 10 years), sex, body weight (± 20%), and smoking status to at least 1 hepatic impairment participant in Groups 2, 3 and/or 4.

Groups 2 to 4 •Participants with mild, moderate or severe hepatic impairment must have a Child-Pugh score clinically determined at screening and confirmed unchanged at baseline calculated as per the Child-Pugh classification in line with the hepatic impairment status of each Group

Exclusion Criteria:

All Participants

• Use of drugs (prescription, non-prescription and herbal remedies such as St John's wort) known to affect CYP3A or UGT1A3, including UGT1A3 inhibitors and inducers and strong and moderate CYP3A inhibitors and inducers, within 4 weeks prior to dosing until completion of the End of Study Visit.
• Acute or chronic hepatitis B or C infection or active infection requiring therapy that will not be completed before screening.

Left ventricular ejection fraction (LVEF) < 50% or below the institutional standard lower limit, whichever is higher, as determined by multiple gated acquisition (MUGA) scan or Trans-thoracic echocardiography (TTE) at screening or baseline.

•At screening, history of retinal vein occlusion (RVO) or presence of predisposing factors to RVO or central serous retinopathy, or any other clinically significant ophthalmologic abnormalities determined by an ophthalmologist.

Group 1

• Any single parameter of alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), or alkaline phosphatase (ALP) exceeding 2.5 × upper limit of normal (ULN) or total bilirubin ≥ 1.5 ULN OR any elevation above ULN of more than 1 parameter of ALT, AST, GGT, ALP, or serum bilirubin at screening or baseline.
• Impaired renal function as indicated by clinically significantly abnormal creatinine or blood urea nitrogen and/or other urea values outside local laboratory ranges or abnormal urinary constituents at screening or baseline.

Groups 2 and 3

• Severe complications of liver disease within the preceding 3 months prior to dosing.
• Hospitalization due to liver disease within the preceding 1 month prior to dosing.
• Participant has received liver transplant at any time in the past and is on immunosuppressant therapy.
• Participants requiring paracentesis more than every 3 weeks for the management of ascites are excluded.

Other protocol-defined inclusion/exclusion criteria may apply.
