). 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. Consider supportive care with transfusions or growth factors as needed. 0 Darzalex SC (daratumumab injection) Page 16 of 144 Administration-Related Reactions Darzalex SC can cause severe and/or serious administration-related reactions (ARRs), including anaphylactic reactions.
In clinical trials with Darzalex SC in patients with multiple myeloma (n=1253) or light chain (AL) amyloidosis (n=193), ARRs (defined as administration-related systemic reactions) were reported in approximately 7% of patients. Most ARRs occurred following the first injection and were Grade 1-2.
ARRs occurring with subsequent injections were seen in 1% of patients. Severe ARRs occurred in 1% of patients treated with Darzalex SC. 08-83 hours). The majority of ARRs occurred on the day of treatment. Delayed ARRs have occurred in 1% of patients.
Signs and symptoms of ARRs may include respiratory symptoms, such as nasal congestion, cough, throat irritation, allergic rhinitis, wheezing as well as pyrexia, chest pain, pruritis, chills, vomiting, nausea, hypotension, and blurred vision.
Severe reactions have occurred, including bronchospasm, hypoxia, dyspnea, hypertension, tachycardia and ocular adverse events (including choroidal effusion, acute myopia and acute angle closure glaucoma) (see 8 ADVERSE REACTIONS). 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.
To reduce the risk of delayed ARRs, administer oral corticosteroids to all patients after each injection of Darzalex SC. g. inhaled corticosteroids, short and long acting bronchodilators) for patients with a history of chronic obstructive pulmonary disease to manage respiratory complications should they occur.
Pre- and post-injection medications may vary when Darzalex SC is used in combination therapy. If ocular symptoms occur, interrupt Darzalex SC and seek immediate ophthalmologic evaluation prior to restarting Darzalex SC (see 4 DOSAGE AND ADMINISTRATION).
Hypogammaglobulinemia Hypogammaglobulinemia can occur in patients treated with Darzalex SC. Immunoglobulin levels should be monitored during treatment with Darzalex SC. In patients with low immunoglobulin levels, pre-emptive measures according to local guidelines such as infection precautions, antibiotic prophylaxis and immunoglobulin replacement should be considered.

Hepatitis B Virus Reactivation Hepatitis B Virus (HBV) reactivation, in some cases fatal, has been reported in patients treated with daratumumab. HBV screening should be performed in all patients before initiation of treatment with 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. Monitoring and Laboratory Tests Interference with indirect antiglobulin test (indirect Coombs test) Daratumumab binds to CD38 found at low levels on red blood cells (RBCs) and may result in a positive indirect Coombs test.
Daratumumab-mediated positive indirect Coombs test may persist for up to 6 months after the last daratumumab dose. […]
