Months reduction in the risk of disease progression or death with DARZALEX ® + Vd
CASTOR was an open-label , randomized , active-controlled phase 3 trial comparing treatment with DARZALEX ® 16 mg / kg + Vd ( n = 251 ) to Vd alone ( n = 247 ) in multiple myeloma patients who received a minimum of 1 prior therapy . Patients receiving DARZALEX ® were treated with pre- and post-infusion medications . DARZALEX ® was given until disease progression . Ef� cacy was evaluated by PFS based on International Myeloma Working Group ( IMWG ) criteria . 1 , 2

Important Safety Information ( cont ’ d )
Interference with Determination of Complete Response
Daratumumab is a human IgG kappa monoclonal antibody that can be detected on both the serum protein electrophoresis ( SPE ) and immuno� xation ( IFE ) assays used for the clinical monitoring of endogenous M-protein . This interference can impact the determination of complete response and of disease progression in some patients with IgG kappa myeloma protein .
Adverse Reactions
In patients who received DARZALEX ® in combination with lenalidomide and dexamethasone , the most frequently reported adverse reactions ( incidence ≥20 %) were : neutropenia ( 92 %), thrombocytopenia ( 73 %), upper respiratory tract infection ( 65 %), infusion reactions ( 48 %), diarrhea ( 43 %), fatigue ( 35 %), cough ( 30 %), muscle spasms ( 26 %), nausea ( 24 %), dyspnea ( 21 %) and pyrexia ( 20 %). The overall incidence of serious adverse reactions was 49 %. Serious adverse reactions were pneumonia ( 12 %), upper respiratory tract infection ( 7 %), in� uenza ( 3 %) and pyrexia ( 3 %).
DRUG INTERACTIONS
Effect of Other Drugs on Daratumumab : The coadministration of lenalidomide or bortezomib with DARZALEX ® did not affect the pharmacokinetics of daratumumab .
Effect of Daratumumab on Other Drugs : The coadministration of DARZALEX ® with bortezomib did not affect the pharmacokinetics of bortezomib .
