). Serious cardiac disorders occurred in 16% and fatal cardiac disorders occurred in 10% of patients. Patients with NYHA Class IIIA or Mayo Stage IIIA disease may be at greater risk. Patients with NYHA Class IIIB or IV were not studied.
Monitor patients with cardiac involvement of AL amyloidosis more frequently for cardiac adverse reaction and administer supportive care as appropriate. Hematologic Neutropenia/Thrombocytopenia Darzalex SC alone or in combination with other medications increases neutropenia.
In lower body weight patients receiving Darzalex SC, further increases in the rate of neutropenia and thrombocytopenia, including higher rates of Grade 3-4 events, were observed. When used in combination with background therapy, Darzalex SC increases neutropenia and thrombocytopenia induced by the background therapy (see 8 ADVERSE REACTIONS).
Monitor complete blood cell counts periodically during treatment according to manufacturer’s prescribing information for background therapies. Monitor patients with neutropenia for signs of infection. Darzalex SC dose delay may be required to allow recovery of blood cell counts (neutrophils or platelets).
No dose reduction is recommended.

Pre medicate patients with antihistamines, antipyretics and corticosteroids to reduce the risk of ARRs prior to treatment with Darzalex SC.
Patients should be monitored and counselled regarding ARRs, especially during and following the first and second injections. If an anaphylactic reaction or life threatening (Grade 4) reactions occur, institute appropriate emergency care and permanently discontinue Darzalex SC.

For patients with evidence of positive HBV serology, monitor for clinical and laboratory signs of HBV reactivation during, and for at least six months following the end of Darzalex SC treatment. Manage patients according to current clinical guidelines.
Consider consulting a hepatitis disease expert as clinically indicated. In patients who develop reactivation of HBV while on Darzalex SC, suspend treatment with Darzalex SC and any concomitant steroids, chemotherapy, and institute appropriate treatment.
Resumption of Darzalex SC treatment in patients whose HBV reactivation is adequately controlled should be discussed with physicians with expertise in managing HBV.
