Criteria

Inclusion Criteria:

  1. All subjects:

    • Written informed consent is obtained
  2. Subjects with normal hepatic function:

    • The subject is in generally good health (age-appropriate) as determined by medical and psychiatric history, physical examination, ECG, serum chemistry, hematology, coagulation, urinalysis, and serology.
  3. Subjects with hepatic impairment:

    • The subject's health is otherwise clinically stable as determined by medical history, physical examination, ECG, serum chemistry, hematology, coagulation parameters (PT, activated partial thromboplastin time [aPTT], and international normalized ratio [INR]), urinalysis, and serology except for those signs and symptoms attributable to liver disease.
    • The subject has case record notes demonstrating physical signs consistent with 1 or more of the following characteristic clinical manifestations of liver cirrhosis: liver firmness to palpation, splenic enlargement, spider angiomas, palmar erythema, parotid hypertrophy, testicular atrophy, ascites (accumulation of fluid in the abdominal cavity), or gynecomastia.
    • The subject has a Child-Pugh Classification score of 7-9 points (moderate).

Exclusion Criteria:

  1. All subjects:

    • The subject has any clinically significant, uncontrolled medical condition.
    • The subject is a poor metabolizer of CYP2D6 substrates based on genotyping performed at screening.
    • The subject has previously participated in a study with CEP-33237.
    • The subject has a known sensitivity or idiosyncratic reaction to hydrocodone or hydromorphone, related compounds, or to any metabolites, or any compound listed as being present in a study formulation.
  2. Subjects with normal hepatic function:

    • The subject has a positive test result for HBsAg or antibodies to hepatitis C.
    • The subject has a history of alcohol, narcotic, or any other substance abuse.
  3. Subjects with hepatic impairment:

    • The subject has severe ascites.
    • The subject has an acute exacerbation of liver disease as indicated by worsening clinical signs of hepatic impairment.
