About

This is a Phase 1 non randomized, open label, single dose, parallel cohort study to investigate the effect of hepatic impairment on the PK, safety and tolerability of PF 04965842.

Full description

A minimum of 24 subjects with normal, mild or moderate hepatic function will be enrolled into the study, with approximately 8 subjects in each cohort. The Child Pugh classification score will be utilized to assess entry criteria and to assign subjects into the appropriate hepatic impairment group. For individual subjects, the total maximum duration of study participation from the Screening visit to the end of clinical research unit (CRU) stay is approximately 31 days and approximately 63 days from the Screening visit to the Follow up contact.

  • Subjects who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, and other study procedures.

Additional Inclusion Criteria for subjects with hepatic impairment:

  • Satisfy the criteria for Class A or Class B of the Child Pugh classification (mild: Child Pugh Scores 5 to 6 points, and moderate: Child Pugh Scores 7 to 9 points), within 14 days of investigational product administration.
  • A diagnosis of hepatic dysfunction due to hepatocellular disease (and not secondary to any acute ongoing hepatocellular process) documented by medical history, physical examination, liver biopsy, hepatic ultrasound, computerized tomography scan, or magnetic resonance imaging (MRI).

Exclusion criteria

  • Subjects with clinically significant infections within the past 3 months (for example, those requiring hospitalization, or as judged by the Investigator), evidence of any infection (including influenza) within the past 7 days, history of disseminated herpes simplex infection or recurrent (>1 episode) or disseminated herpes zoster.
  • Subjects with a malignancy or with a history of malignancy, with the exception of adequately treated or excised non metastatic basal cell or squamous cell cancer of the skin or cervical carcinoma in situ.

Additional exclusion criteria for subjects with hepatic impairment:

  • Hepatic carcinoma or hepatorenal syndrome or limited predicted life expectancy (defined as less than 1 year).
  • Subjects who have previously had a transplanted kidney, liver, or heart.
  • At Screening, persistent severe, uncontrolled hypertension.
