A Phase I, Multicenter, Open-label, Single-dose Study to Assess the Pharmacokinetics of MEK162 in Subjects With Mild, Moderate and Severe Hepatic Impairment

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.


Inclusion Criteria:

- Written informed consent prior to any screening procedures

- Male or female (postmenopausal or sterilized)

- Subject body weight at least 45 kg and a body mass index (BMI) in the range of 18 to
35.0 kg/m2

- Subjects with normal hepatic function must have total bilirubin ≤ upper limit of
normal (≤ ULN), alanine aminotransferase (ALT), aspartate aminotransferase (AST),
gamma-glutamyl transferase (GGT) and alkaline phosphatase (AP) ≤ ULN, serum
creatinine ≤ ULN, serum amylase and lipase ≤ ULN

Additional inclusion criteria for subjects with abnormal liver function determined by
elevation of serum total bilirubin are:

- Absolute neutrophil count (ANC) > 1000 cell/mm3

- Hb > 9 mg/dl,

- Platelet count > 30,000/mm3

- Serum creatinine ≤ 1.8 mg/dl

- Otherwise considered healthy and free of significant medical disorders unrelated to
the subject's hepatic disorder

Exclusion Criteria:

- Women of child-bearing potential

- Pregnant or nursing (lactating) women

- Subjects with impaired cardiovascular function or clinically significant
cardiovascular diseases

- Uncontrolled arterial hypertension despite medical treatment

- History or current evidence of retinal vein occlusion (RVO) or current risk factors
of RVO (e.g. uncontrolled glaucoma or ocular hypertension, history of hyperviscosity
or hypercoagulability syndromes),

- History of Gilbert's syndrome

- Immuno-compromised subjects (including known history/seropositivity of HIV)

- 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)

- Subjects who have undergone major surgery ≤ 3 weeks prior to starting study drug or
who have not recovered from side effects of such procedure

- History of clinically significant drug allergy

- Prior therapy with a MEK-inhibitor

- Use of an investigational drug within 30 days of screening

- Current smoker or has used tobacco products or products containing nicotine within 7
days prior to dosing of study drug

- Consumption of alcohol within 3 days prior to dosing or during the study

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. ALT and
AST beyond the normal range before inclusion Presence of impaired renal function as
indicated by abnormal creatinine (creatinine clearance < 80 mL/min) values and/or serum
creatinine ≥1.8 mg/dL- A positive Hepatitis B or Hepatitis C test result

Additional exclusion criteria for subjects with elevation of serum bilirubin > UNL:

- Symptoms or history of encephalopathy (Grade II or worse) within 4 weeks of study
entry

- Clinical evidence of severe ascites requiring intervention

- International normalized ratio (INR) >2.5

- Any evidence of progressive liver disease within the last 3 weeks prior to the
screening visit) as indicated by worsening of clinical manifestations (i.e.: ascites,
encephalopathy) and/or laboratories abnormalities (liver transaminases, alkaline
phosphatase and GGT or a ≥ 50% worsening of serum bilirubin or prothrombin time)

- History of surgical portosystemic shunt with complications (i.e. hepatic
encephalopathy, heart failure)

- Active bleeding during the last 28 days prior to dosing including variceal bleeding
