Uses
1 INDICATIONS AND USAGE MONJUVI, in combination with lenalidomide, is indicated for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) not otherwise specified, including DLBCL arising from low grade lymphoma, and who are not eligible for autologous stem cell transplant (ASCT). This indication is approved under accelerated approval based on overall response rate [see Clinical Studies (14) ] . Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).
Dosage
2 DOSAGE AND ADMINISTRATION Administer premedications prior to starting MONJUVI. ( 2.2 ) The recommended dosage of MONJUVI is 12 mg/kg as an intravenous infusion according to the following dosing schedule: ( 2.1 ) 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. Cycle 4 and beyond: Days 1 and 15 of each 28-day cycle. Administer MONJUVI in combination with lenalidomide for a maximum of 12 cycles and then continue MONJUVI as monotherapy until disease progression or unacceptable toxicity. ( 2.1 ) See Full Prescribing Information for instructions on preparation and administration.

Warnings
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) ] . 4 CONTRAINDICATIONS None. None.
Pregnancy
8.1 Pregnancy Risk Summary Based on its mechanism of action, MONJUVI may cause fetal B-cell depletion when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no available data on MONJUVI use in pregnant women to evaluate for a drug-associated risk. Animal reproductive toxicity studies have not been conducted with tafasitamab-cxix. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
