Traceability In order to improve the traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded. 8). These reactions can be life-threatening and fatal outcomes have been reported.
All patients should be monitored throughout the infusion for IRRs. For patients that experience any grade IRRs, continue monitoring post-infusion until symptoms resolve. In clinical studies, IRRs were reported in approximately half of all patients treated with DARZALEX.
8). Four percent of all patients had an IRR at more than one infusion. Severe reactions have occurred, including bronchospasm, hypoxia, dyspnoea, hypertension, laryngeal oedema, pulmonary oedema and ocular adverse reactions (including choroidal effusion, acute myopia and acute angle closure glaucoma).
Symptoms predominantly included nasal congestion, cough, throat irritation, chills, vomiting and nausea. 8). Patients should be pre-medicated with antihistamines, antipyretics and corticosteroids to reduce the risk of IRRs prior to treatment with DARZALEX.
DARZALEX infusion should be interrupted for IRRs of any severity and medical management/supportive treatment for IRRs should be instituted as needed. For patients with grade 1, 2, or 3 IRRs, the infusion rate should be reduced when re-starting the infusion.
If an anaphylactic reaction or life-threatening (grade 4) infusion reaction occurs, appropriate emergency resuscitation should be initiated immediately. 3). To reduce the risk of delayed IRRs, oral corticosteroids should be administered to all patients following DARZALEX infusions.
g. inhaled corticosteroids, short and long acting bronchodilators) should be considered for patients with a history of chronic obstructive pulmonary disease to manage respiratory complications should they occur. 2). 8). Complete blood cell counts should be monitored periodically during treatment according to prescribing information for background therapies.

a Indicates grouping of terms. b Post-marketing adverse reaction. c Infusion-related reaction includes terms determined by investigators to be related to infusion, see below. d Incidence is based on a subset of patients who received at least one dose of study treatment on or after 01 February 2020 (the start of the COVID-19 pandemic) from studies MMY3003, MMY3006, MMY3008 and MMY3013, and all daratumumab treated patients from studies MMY3014, MMY3019, and SMM3001 (N=1177).
e Musculoskeletal pain includes back pain, flank pain, groin pain, musculoskeletal chest pain, musculoskeletal pain, musculoskeletal stiffness, myalgia, neck pain, non-cardiac chest pain, and pain in extremity. Description of selected adverse reactions Infusion-related reactions (IRRs) In clinical studies (monotherapy and combination treatments; N=2066) the incidence of any grade IRRs was 37% with the first (16 mg/kg, week 1) infusion of DARZALEX, 2% with the week 2 infusion, and cumulatively 6% with subsequent infusions.
Less than 1% of patients had a grade 3/4 IRR with the week 2 or subsequent infusions. 8 hours). The incidence of infusion modifications due to reactions was 36%. Median durations of 16 mg/kg infusions for the 1st week, 2nd week and subsequent infusions were approximately 7, 4 and 3 hours respectively.
Severe IRRs included bronchospasm, dyspnoea, laryngeal oedema, pulmonary oedema, ocular adverse reactions (including choroidal effusion, acute myopia and acute angle closure glaucoma), hypoxia, and hypertension. 4). 9) months, upon re-initiation of DARZALEX the incidence of IRRs was 11% at first infusion following ASCT.
Infusion rate/dilution volume used upon re-initiation was that used for the last DARZALEX infusion prior to interruption due to ASCT. IRRs occurring at re-initiation of DARZALEX following ASCT were consistent in terms of symptoms and severity (grade 3/4: < 1%) with those reported in previous studies at week 2 or subsequent infusions.
In study MMY1001, patients receiving daratumumab combination treatment (n=97) […]
Patients with neutropenia should be monitored for signs of infection. DARZALEX delay may be required to allow recovery of blood cell counts. No dose reduction of DARZALEX is recommended. Consider supportive care with transfusions or growth factors.
8). Patients should be closely monitored for signs and symptoms of infection prior to and during treatment with DARZALEX and treated appropriately. 2). 8 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 infusion. It should be recognised that daratumumab bound to RBCs may mask detection of antibodies to minor antigens in the patient’s serum.
The determination of a patient’s ABO and Rh blood type are not impacted. Patients should be typed and screened prior to starting daratumumab treatment. Phenotyping may be considered prior to starting daratumumab treatment as per local practice.
Red blood cell genotyping is not impacted by daratumumab and may be performed at any time. 5). If an emergency transfusion is required, non-cross-matched ABO/RhD-compatible RBCs can be given per local blood bank practices. 5). This interference can impact the determination of complete response and of disease progression in some patients with IgG kappa myeloma protein.
Hepatitis B virus (HBV) reactivation Hepatitis B virus reactivation, in some cases fatal, has been reported in patients treated with DARZALEX. HBV screening should be performed in all patients before initiation of treatment with DARZALEX.
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 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, suspend treatment with DARZALEX and institute appropriate treatment. Resumption of DARZALEX treatment in patients whose HBV reactivation is adequately controlled should be discussed with physicians with expertise in managing HBV.
