MEK162 in Healthy Subjects With Normal Hepatic Function and Subjects With Impaired Hepatic Function

Stopped early · Phase 1

Conditions studied: Hepatic Impairment

In brief

This study is a phase I, multi-center, open-label, single oral dose, parallel group study to assess the PK and safety of MEK162 in subjects with impaired hepatic function and healthy subjects with normal hepatic function. Subjects will be assigned by hepatic function defined by elevation of serum total bilirubin and serum AST as determined at the screening and baseline visits. The study population will be healthy male and postmenopausal or sterile female subjects who meet all of the inclusion and none of the exclusion criteria. A minimum of 24 evaluable subjects (6 subjects per group) will be enrolled. The groups are: Group 1-healthy volunteers, Group 2-Mild hepatic impairment, Group 3-Moderate hepatic impairment and Group 4-Severe hepatic impairment. Once approved for enrollment, participants will be confined to the facility for 5 days, given a single dose of MEK162 and monitored for safety assessments, labs and PK will be assessed.

• Any surgical or medical condition (other than hepatic impairment) or receiving any pharmacological treatment which might significantly alter the absorption or metabolism of drugs or which may jeopardize the subject in case of participation in the study
• Antecedent of malignancy with the following exceptions: adequately treated basal cell or squamous cell carcinoma of the skin
• Subjects who have neuromuscular disorders that are associated with elevated CK (e.g., inflammatory myopathies, muscular dystrophy, amyotrophic lateral sclerosis, spinal muscular atrophy)

• Additional exclusion criteria for subjects with normal hepatic function:
• Clinical evidence of liver disease or liver injury as indicated by abnormal liver function tests such as ALT, AST, GGT, alkaline phosphatase, or serum bilirubin.
