MONJUVI

5 WARNINGS AND PRECAUTIONS Infusion-Related Reactions : Monitor patients frequently during infusion. Interrupt or discontinue infusion based on severity. ( 2.3 , 5.1 ) Myelosuppression : Monitor complete blood counts. Manage using dose modifications and growth factor support. Interrupt or discontinue MONJUVI based on severity. ( 2.3 , 5.2 ) Infections : Bacterial, fungal and viral infections can occur during and following MONJUVI. Monitor patients for infections. ( 2.3 , 5.3 ) Embryo-Fetal Toxicity : May cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and use of effective contraception. ( 5.4 ) 5.1 Infusion-Related Reactions MONJUVI can cause infusion-related reactions [see Adverse Reactions (6.1) ] . In L-MIND, infusion-related reactions occurred in 6% of the 81 patients. Eighty percent of infusion-related reactions occurred during cycle 1 or 2. Signs and symptoms included fever, chills, rash, flushing, dyspnea, and hypertension. These reactions were managed with temporary interruption of the infusion and/or with supportive medication. Premedicate patients prior to starting MONJUVI infusion [see Dosage and Administration (2.2) ] . Monitor patients frequently during infusion. Based on the severity of the infusion-related reaction, interrupt or discontinue MONJUVI [ see Dosage and Administration (2.3) ] . Institute appropriate medical management. 5.2 Myelosuppression MONJUVI can cause serious or severe myelosuppression, including neutropenia, thrombocytopenia, and anemia [see Adverse Reactions (6.1) ] . In L-MIND, Grade 3 neutropenia occurred in 25% of patients, thrombocytopenia in 12%, and anemia in 7%. Grade 4 neutropenia occurred in 25% and thrombocytopenia in 6%. Neutropenia led to treatment discontinuation in 3.7% of patients. Monitor CBC prior to administration of each treatment cycle and throughout treatment. Monitor patients with neutropenia for signs of infection. Consider granulocyte colony-stimulating factor administration. Withhold MONJUVI based on the severity of the adverse reaction [see Dosage and Administration (2.3) ]. Refer to the lenalidomide prescribing information for dosage modifications. 5.3 Infections Fatal and serious infections, including opportunistic infections, occurred in patients during treatment with MONJUVI and following the last dose [see Adverse Reactions (6.1) ]. In L-MIND, 73% of the 81 patients developed an infection. The most frequent infections were respiratory tract infection (24%), urinary tract infection (17%), bronchitis (16%), nasopharyngitis (10%) and pneumonia (10%). Grade 3 or higher infection occurred in 30% of the 81 patients. The most frequent grade 3 or higher infection was pneumonia (7%). Infection-related deaths were reported in 2.5% of the 81 patients. Monitor patients for signs and symptoms of infection and manage infections as appropriate. 5.4 Embryo-Fetal Toxicity Based on its mechanism of action, MONJUVI may cause fetal B-cell depletion when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with MONJUVI and for at least 3 months after the last dose [see Use in Specific Populations (8.1 , 8.3) ] . MONJUVI is initially administered in combination with lenalidomide. The combination of MONJUVI with lenalidomide is contraindicated in pregnant women because lenalidomide can cause birth defects and death of the unborn child. Refer to the lenalidomide prescribing information on use during pregnancy.

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Infusion-related reactions [see Warnings and Precautions (5.1) ] Myelosuppression [see Warnings and Precautions (5.2) ] Infections [see Warnings and Precautions (5.3) ] The most common adverse reactions (≥20%) are neutropenia, fatigue, anemia, diarrhea, thrombocytopenia, cough, pyrexia, peripheral edema, respiratory tract infection, and decreased appetite.

Relapsed or Refractory Diffuse Large B-Cell Lymphoma The safety of MONJUVI was evaluated in L-MIND [see Clinical Studies (14) ]. Patients (n=81) received MONJUVI 12 mg/kg intravenously in combination with lenalidomide for a maximum of 12 cycles, followed by MONJUVI as monotherapy until disease progression or unacceptable toxicity as follows: Cycle 1: Days 1, 4, 8, 15 and 22 of the 28-day cycle; Cycles 2 and 3: Days 1, 8, 15 and 22 of each 28-day cycle; Cycles 4 and beyond: Days 1 and 15 of each 28-day cycle. Among patients who received MONJUVI, 57% were exposed for 6 months or longer, 42% were exposed for greater than one year, and 24% were exposed for greater than two years. Serious adverse reactions occurred in 52% of patients who received MONJUVI. Serious adverse reactions in ≥6% of patients included infections (26%), including pneumonia (7%), and febrile neutropenia (6%). Fatal adverse reactions occurred in 5% of patients who received MONJUVI, including cerebrovascular accident (1.2%), respiratory failure (1.2%), progressive multifocal leukoencephalopathy (1.2%) and sudden death (1.2%). Permanent discontinuation of MONJUVI or lenalidomide due to an adverse reaction occurred in 25% of patients and permanent discontinuation of MONJUVI due to an adverse reaction occurred in 15%. The most frequent adverse reactions which resulted in permanent discontinuation of MONJUVI were infections (5%), nervous system disorders (2.5%), respiratory, thoracic and mediastinal disorders (2.5%). Dosage interruptions of MONJUVI or lenalidomide due to an adverse reaction occurred in 69% of patients and dosage interruption of MONJUVI due to an adverse reaction occurred in 65%. The most frequent adverse reactions which required a dosage interruption of MONJUVI were blood and lymphatic system disorders (41%), and infections (27%). The most common adverse reactions (≥ 20%) were neutropenia, fatigue, anemia, diarrhea, thrombocytopenia, cough, pyrexia, peripheral edema, respiratory tract infection, and decreased appetite.

Table 4: Select Laboratory Abnormalities (>20%) Worsening from Baseline in Patients with Relapsed or Refractory Diffuse Large B-Cell Lymphoma Who Received MONJUVI in L-MIND Laboratory Abnormality MONJUVI The denominator used to calculate the rate was 74 based on the number of patients with a baseline value and at least one post-treatment value. All Grades (%) Grade 3 or 4 (%) Chemistry Glucose increased 49 5 Calcium decreased 47 1.4 Gamma glutamyl transferase increased 34 5 Albumin decreased 26 0 Magnesium decreased 22 0 Urate increased 20 7 Phosphate decreased 20 5 Creatinine increased 20 1.4 Aspartate aminotransferase increased 20 0 Coagulation Activated partial thromboplastin time increased 46 4.1 6.2 Immunogenicity As with all therapeutic proteins, there is the potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assays. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors, including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies in the studies described below with the incidence of antibodies in other studies or to other tafasitamab products may be misleading. Overall, no treatment-emergent or treatment-boosted anti-tafasitamab antibodies were observed. No clinically meaningful differences in the pharmacokinetics, efficacy, or safety profile of tafasitamab-cxix were observed in 2.5% of 81 patients with relapsed or refractory DLBCL with pre-existing anti-tafasitamab antibodies in L-MIND.
