Risk of Hepatotoxicity

Monitoring of Transaminases

  • Before initiating KYNAMRO and during treatment, monitor transaminases as recommended in Table 2.

Table 2: Recommendations for Monitoring Transaminases

  • Before initiating treatment
    • Measure ALT, AST, alkaline phosphatase, and total bilirubin.
    • If abnormal, consider initiating KYNAMRO only after an appropriate work-up and the baseline abnormalities have been explained or resolved.
    • KYNAMRO is contraindicated in patients with moderate or severe hepatic impairment, or active liver disease, including unexplained persistent elevations of serum transaminases.
  • During the first year
    • Measure liver-related tests (ALT and AST, at a minimum) prior to each increase in dose or monthly, whichever occurs first.
    • After the first year
    • Measure liver-related tests (ALT and AST, at a minimum) at least every 3 months and before any increase in dose.
  • At any time during treatment
    • If transaminases are abnormal, reduce or withhold dosing of KYNAMRO and monitor as recommended.
    • Discontinue JUXTAPID for persistent or clinically significant elevations.
    • If transaminase elevations are accompanied by clinical symptoms of liver injury (such as nausea, vomiting, abdominal pain, fever, jaundice, lethargy, flu-like symptoms), increases in bilirubin =2x ULN, or active liver disease, discontinue treatment with JUXTAPID and identify the probable cause.
