Hepatic Impairment (revised)
  • No adjustment to the starting dose is required for patients with mild or moderate hepatic impairment. KADCYLA was not studied in patients with severe hepatic impairment. Closely monitor patients with hepatic impairment due to known hepatotoxicity observed with KADCYLA.

  • Embryo-Fetal Toxicity: Exposure to KADCYLA during pregnancy can result in embryo-fetal harm. Advise patients of these risks and the need for effective contraception.

  • …In clinical trials… one of which was fatal…NRH should be considered … and/or cirrhosis-like pattern seen on the computed tomography (CT) scan of the liver... 
  • Cases of hemorrhagic events, including central nervous system, respiratory, and gastrointestinal hemorrhage, have been reported in clinical trials with Kadcyla. Some of these bleeding events resulted in fatal outcomes. In the randomized trial (Study 1), the overall frequency of hemorrhage was 32.2% in the KADCYLA-treated group and 16.4% in the lapatinib plus capecitabine-treated group. The incidence of ≥ Grade 3 hemorrhage was 1.8% in the KADCYLA-treated group and 0.8% in the lapatinib plus capecitabine-treated group [see Adverse Reactions (6.1)]. Although, in some of the observed cases the patients were also receiving anti-coagulation therapy, antiplatelet therapy, or had thrombocytopenia, in others there were no known additional risk factors. Use caution with these agents and consider additional monitoring when concomitant use is medically necessary.
