Premedications may include acetaminophen, histamine H 1 receptor antagonists, histamine H 2 receptor antagonists, and/or glucocorticosteroids. For patients not experiencing infusion-related reactions during the first 3 infusions, premedication is optional for subsequent infusions. If a patient experiences an infusion-related reaction, administer premedications before each subsequent infusion. Thromboprophylaxis Refer to the lenalidomide prescribing information for recommendations on prophylaxis for venous and arterial thrombotic events. 2.5 Dosage Modifications for Adverse Reactions The recommended dosage modifications for adverse reactions are summarized in Table 3. Table 3: Dosage Modifications for Adverse Reactions Adverse Reaction Severity MONJUVI Dosage Modification Infusion-related reactions [see Warnings and Precautions ( 5.1 )] Ensure premedications administered before subsequent infusions [see Dosage and Administration (2.4)]. Grade 2 (moderate) Interrupt infusion immediately and manage signs and symptoms. Once signs and symptoms resolve or reduce to Grade 1, resume infusion at no more than 50% of the rate at which the reaction occurred. If the patient does not experience further reaction within 1 hour and vital signs are stable, the infusion rate may be increased every 30 minutes as tolerated to the rate at which the reaction occurred. Grade 3 (severe) Interrupt infusion immediately and manage signs and symptoms. Once signs and symptoms resolve or reduce to Grade 1, resume infusion at no more than 25% of the rate at which the reaction occurred. If the patient does not experience further reaction within 1 hour and vital signs are stable, the infusion rate may be increased every 30 minutes as tolerated to a maximum of 50% of the rate at which the reaction occurred. If Grade 3 reaction returns, stop the infusion immediately and permanently discontinue MONJUVI. Grade 4 (life-threatening) Stop the infusion immediately and permanently discontinue MONJUVI. Myelosuppression [see Warnings and Precautions ( 5.2 )] Platelet count of 50,000/mcL or less Withhold MONJUVI and lenalidomide and monitor complete blood count (CBC) weekly until platelet count is 50,000/mcL or higher. Resume MONJUVI at the same dose and lenalidomide at a reduced dose. Refer to lenalidomide prescribing information for dosage modifications. Neutrophil count of 1,000/ mcL or less for at least 7 days OR Neutrophil count of 1,000/ mcL or less with an increase of body temperature to 100.4°F (38°C) or higher OR Neutrophil count less than 500/mcL Withhold MONJUVI and lenalidomide and monitor CBC weekly until neutrophil count is 1,000/ mcL or higher. Resume MONJUVI at the same dose and lenalidomide at a reduced dose. Refer to lenalidomide prescribing information for dosage modifications. 2.6 Preparation and Administration Reconstitute and dilute MONJUVI prior to infusion. Reconstitution Calculate the dose (mg) and determine the number of vials needed. Reconstitute each 200 mg MONJUVI vial with 5 mL Sterile Water for Injection, USP with the stream directed toward the wall of each vial to obtain a final concentration of 40 mg/mL tafasitamab-cxix. Gently swirl the vial(s) until completely dissolved. Do not shake or swirl vigorously. Complete dissolution may take up to 5 minutes. Visually inspect the reconstituted solution for particulate matter or discoloration. The reconstituted solution should appear as a colorless to slightly yellow solution. Discard the vial(s) if the solution is cloudy, discolored, or contains visible particles. Use the reconstituted MONJUVI solution immediately. If needed, store the reconstituted solution in the vial for a maximum of 12 hours either refrigerated at 36°F to 46°F (2°C to 8°C) or room temperature at 68°F to 77°F (20°C to 25°C) before dilution. Protect from light during storage. Dilution Determine the volume (mL) of the 40 mg/mL reconstituted MONJUVI solution needed based on the required dose. Remove a volume equal to the required MONJUVI solution from a 250 mL 0.9% Sodium Chloride Injection, USP infusion bag and discard it. Withdraw the necessary amount of MONJUVI and slowly dilute in the infusion bag that contains the 0.9% Sodium Chloride Injection, USP to a final concentration of 2 mg/mL to 8 mg/mL. Discard any unused portion of MONJUVI remaining in the vial. Gently mix the intravenous bag by slowly inverting the bag. Do not shake . Visually inspect the infusion bag with the diluted MONJUVI infusion solution for particulate matter and discoloration prior to administration. If not used immediately, store the diluted MONJUVI infusion solution refrigerated for up to 18 hours at 36°F to 46°F (2°C to 8°C) and/or at room temperature for up to 12 hours at 68°F to 77°F (20°C to 25°C). The room temperature storage includes time for infusion. Protect from light during storage. Do not shake or freeze the reconstituted or diluted infusion solutions. Administration Administer MONJUVI as an intravenous infusion. For the first infusion, use an infusion rate of 70 mL/h for the first 30 minutes, then, increase the rate so that the infusion is administered within 1.5 to 2.5 hours. Administer all subsequent infusions within 1.5 to 2 hours. Infuse the entire contents of the bag containing MONJUVI. Do not co-administer other drugs through the same infusion line. No incompatibilities have been observed between MONJUVI with infusion containers made of polypropylene (PP), polyvinylchloride (PVC), polyethylene (PE), polyethylene terephthalate (PET), or glass and infusion sets made of polyurethane (PUR) or PVC.

Relapsed or Refractory Diffuse Large B-cell Lymphoma The safety of MONJUVI in patients with relapsed or refractory DLBCL was evaluated in L-MIND [see Clinical Studies ( 14 .1 )]. 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.
