Indication ADCETRIS is indicated for the treatment of patients with classical HL at high risk of relapse or progression as post autologous hematopoietic stem cell transplantation (auto-HSCT) consolidation. Important Safety Information BOXED WARNING the infusion and institute appropriate medical management. If anaphylaxis occurs, immediately and permanently discontinue the infusion and administer appropriate medical therapy. Patients who experienced a prior infusion-related reaction should be premedicated for subsequent infusions. Premedication may include acetaminophen, an antihistamine, and a corticosteroid. severe renal impairment compared to patients with normal renal function. Avoid the use of ADCETRIS in patients with severe renal impairment. • Increased toxicity in the presence of moderate or severe hepatic impairment: The frequency of ≥Grade 3 adverse reactions and deaths was greater in patients with moderate or severe hepatic impairment compared to patients with normal hepatic function. Avoid the use of ADCETRIS in patients with moderate or severe hepatic impairment. • Hematologic toxicities: Prolonged (≥1 week) severe neutropenia and Grade 3 or 4 thrombocytopenia or anemia can occur with ADCETRIS. Febrile neutropenia has been reported • Hepatotoxicity: Serious cases of hepatotoxicity, with ADCETRIS. Monitor complete blood counts including fatal outcomes, have occurred prior to each dose of ADCETRIS and consider with ADCETRIS. Cases were consistent with Contraindication: more frequent monitoring for patients with Grade hepatocellular injury, including elevations of ADCETRIS is contraindicated with concomitant 3 or 4 neutropenia. Monitor patients for fever. If transaminases and/or bilirubin, and occurred bleomycin due to pulmonary toxicity (e.g., interstitial Grade 3 or 4 neutropenia develops, consider dose after the first dose of ADCETRIS or rechallenge. infiltration and/or inflammation). delays, reductions, discontinuation, or G-CSF Preexisting liver disease, elevated baseline liver prophylaxis with subsequent doses.

Monitor liver enzymes and causes a PN that is predominantly sensory. Cases Infections such as pneumonia, bacteremia, and bilirubin. Patients experiencing new, worsening, of motor PN have also been reported. ADCETRISsepsis or septic shock (including fatal outcomes) or recurrent hepatotoxicity may require a delay, induced PN is cumulative.

In addition to ADCETRIS therapy, other possible contributory factors include prior
