Administration
MONJUVI can cause infusion-related reactions [see Adverse Reactions (6.1)].
In L-MIND, infusion-related reactions occurred in 6% of the 81 patients with DLBCL who received MONJUVI. Eighty percent of infusion-related reactions occurred during cycle 1 or 2. In inMIND, infusion-related reactions occurred in 16% of the 274 patients with FL who received MONJUVI in combination with lenalidomide and rituximab. Signs and symptoms included fever, chills, rash, flushing, dyspnea, and hypertension. These reactions were generally managed with temporary interruption of the infusion and/or with supportive medication.
Premedicate patients prior to starting MONJUVI infusion [see Dosage and Administration (2.4)]. Monitor patients frequently during infusion. Based on the severity of the infusion-related reaction, interrupt or discontinue MONJUVI [see Dosage and Administration (2.5)]. Institute appropriate medical management.
MONJUVI can cause serious or severe myelosuppression, including neutropenia, lymphopenia, thrombocytopenia, and anemia [see Adverse Reactions (6.1)].
In L-MIND, among 81 patients with DLBCL who received MONJUVI, Grade 3 neutropenia was reported in 25%, Grade 3 thrombocytopenia in 12%, and Grade 3 anemia in 7%. Grade 4 neutropenia was reported in 25% and Grade 4 thrombocytopenia in 6%. Neutropenia led to treatment discontinuation in 3.7% of the patients with DLBCL. Febrile neutropenia occurred in 12%.
In inMIND, among 274 patients with FL who received MONJUVI in combination with lenalidomide and rituximab, new or worsening Grade 3 or 4 cytopenias included decreased neutrophils in 48% (Grade 4, 19%), decreased lymphocytes in 22% (Grade 4, 1.8%), decreased hemoglobin in 9%, and decreased platelets in 8% (Grade 4, 4%). Febrile neutropenia occurred in 4.4%.
Monitor CBCs before 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 (2.5)]. Refer to the lenalidomide prescribing information for dosage modifications.
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 with DLBCL who received MONJUVI developed an infection. Grade 3 or higher infection occurred in 30%. Infection-related deaths occurred in 2.5% of patients, including a case of progressive multifocal leukoencephalophathy (PML). The most frequent Grade 3 or higher infection was pneumonia (7%). The most frequent infections of any grade were respiratory tract infections (51%, including pneumonias) and urinary tract infection (17%).
Among 274 patients with FL who received MONJUVI in combination with lenalidomide and rituximab in inMIND, Grade 3 or higher infections occurred in 24%, including fatal infections in 1.1% of patients. The most frequent Grade ≥ 3 infections were respiratory tract infections (19%), including Grade 3 or higher pneumonia (14%) and COVID-19 infection (11%). Opportunistic infections of any grade occurred in 6% of patients, including herpes simplex or zoster infection (5%), fungal pneumonia (1.1%, including Pneumocytis jirovecii pneumonia in 0.4%), and cytomegalovirus (CMV) reactivation (0.4%).
Monitor patients for signs and symptoms of infection and manage infections as appropriate. Consider infection prophylaxis per institutional guidelines. Consider treatment with subcutaneous or intravenous immunoglobulin (IVIG) as appropriate
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 3 months after the last dose [see Use in Specific Populations (8.1, 8.3)].
The combination of MONJUVI with lenalidomide and of MONJUVI with lenalidomide and rituximab 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.
The following clinically significant adverse reactions are described elsewhere in the labeling:
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in other clinical trials of another drug and may not reflect the rates observed in practice.
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:
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%), and 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 interruptions 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, respiratory tract infection, fatigue, anemia, diarrhea, thrombocytopenia, cough, pyrexia, peripheral edema, and decreased appetite.

Relapsed or Refractory Follicular Lymphoma
The safety of MONJUVI in patients with relapsed or refractory FL was evaluated in the inMIND trial [see Clinical Studies (14.2)]. Patients received MONJUVI 12 mg/kg (N = 274) or placebo (N = 272) intravenously for a maximum of 12 cycles in combination with lenalidomide 20 mg (Days 1-21 of Cycles 1 to 12) and rituximab 375 mg/m2 (Cycles 1 to 5). MONJUVI was administered as follows:
In the MONJUVI arm, 54% of patients completed all 12 cycles. The median age in that arm was 64 years (range: 36-88 years); 20% were age 75 years or older; 55% were male; 80% were White, 15% Asian, and 0.4% Black.
In the MONJUVI arm, serious adverse reactions occurred in 33% of patients, including serious infections in 24% of patients (including pneumonia and COVID-19 infection). Other serious adverse reactions in ≥ 2% of patients included renal insufficiency (3.3%), second primary malignancies (2.9%), and febrile neutropenia (2.6%). Fatal adverse reactions occurred in 1.5% of patients, including from COVID‑19, sepsis, and adenocarcinoma.
Adverse reactions led to permanent discontinuation of MONJUVI in 11% of patients and dosage interruptions in 74%. The most frequent adverse reactions leading to dosage interruptions of MONJUVI were neutropenia (37% of all patients), COVID-19 (22%), pneumonia (11%), and infusion-related reaction (8%).

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.
MONJUVI is administered in combination with lenalidomide, as well as in combination with lenalidomide and rituximab for up to 12 cycles. Lenalidomide can cause embryo-fetal harm and is contraindicated for use in pregnancy. Refer to the lenalidomide prescribing information for additional information. Lenalidomide is only available through a REMS program.
Clinical Considerations
Fetal/Neonatal Adverse Reactions
Immunoglobulin G (IgG) monoclonal antibodies are transferred across the placenta. Based on its mechanism of action, MONJUVI may cause depletion of fetal CD19 positive immune cells. Defer administering live vaccines to neonates and infants exposed to tafasitamab-cxix in utero until a hematology evaluation is completed.
Data
Animal Data
Animal reproductive studies have not been conducted with tafasitamab-cxix. Tafasitamab-cxix is an IgG antibody and thus has the potential to cross the placental barrier permitting direct fetal exposure and depleting fetal B lymphocytes.
Risk Summary
There are no data on the presence of tafasitamab-cxix in human milk or the effects on the breastfed child or milk production. Maternal immunoglobulin G is known to be present in human milk. The effects of local gastrointestinal exposure and limited systemic exposure in the breastfed infant to MONJUVI are unknown. Because of the potential for serious adverse reactions in the breastfed child, advise women not to breastfeed during treatment with MONJUVI and for 3 months after the last dose. Refer to lenalidomide prescribing information for additional information.
MONJUVI can cause fetal B-cell depletion when administered to a pregnant woman [see Use in Specific Populations (8.1)].
Pregnancy Testing
Refer to the prescribing information for lenalidomide for pregnancy testing requirements prior to initiating the combination of MONJUVI with lenalidomide or the combination of MONJUVI with lenalidomide and rituximab .
Contraception
Females
Advise females of reproductive potential to use effective contraception during treatment with MONJUVI and for 3 months after the last dose. Additionally, refer to the lenalidomide prescribing information for additional recommendations for contraception.
Males
Refer to the lenalidomide prescribing information for recommendations.
The safety and effectiveness of MONJUVI in pediatric patients have not been established.
Relapsed or Refractory Diffuse Large B-Cell Lymphoma
Among the 81 patients who received MONJUVI and lenalidomide in L-MIND, 72% were 65 years and older, while 38% were 75 years and older. Clinical studies of MONJUVI did not include sufficient numbers of patients aged 65 and older to determine whether effectiveness differs compared to that of younger subjects. Patients 65 years and older had more serious adverse reactions (57%) than younger patients (39%).
Relapsed or Refractory Follicular Lymphoma
Among the 274 patients with FL who received MONJUVI in combination with lenalidomide and rituximab in inMIND, 137 (50%) were 65 years and older and 54 (20%) were 75 years and older. No clinically meaningful differences in safety or effectiveness were observed between these patients and younger patients.
Tafasitamab-cxix is a humanized CD19-directed cytolytic monoclonal antibody that contains an IgG1/2 hybrid Fc-domain with 2 amino acid substitutions to modify the Fc-mediated functions of the antibody. It is produced by recombinant DNA technology in mammalian cells (Chinese hamster ovary). Tafasitamab-cxix has a molecular weight of approximately 150 kDa.
MONJUVI (tafasitamab-cxix) for injection is supplied as a sterile, preservative-free, white to slightly yellowish lyophilized powder in a single-dose vial for intravenous use after reconstitution and further dilution. After reconstitution with 5 mL of Sterile Water for Injection, USP, the resulting concentration is 40 mg/mL with a pH of 6.0. Each single-dose vial contains 200 mg tafasitamab-cxix, citric acid monohydrate (3.7 mg), polysorbate 20 (1 mg), sodium citrate dihydrate (31.6 mg) and trehalose dihydrate (378.3 mg).
Tafasitamab-cxix is an Fc-modified monoclonal antibody that binds to CD19 antigen expressed on the surface of pre-B and mature B lymphocytes and on several B-cell malignancies, including diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL).
Upon binding to CD19, tafasitamab-cxix mediates B-cell lysis through apoptosis and immune effector mechanisms, including antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP).
In studies conducted in vitro in DLBCL tumor cells, tafasitamab-cxix in combination with lenalidomide resulted in increased ADCC activity compared to tafasitamab-cxix or lenalidomide alone.
Tafasitamab-cxix reduced peripheral blood B cell counts by 97% after 8 days of treatment in patients with relapsed or refractory DLBCL. Nadir, with a reduction to undetectable levels (< 1 cell/microliter), was reached within 16 weeks of treatment.
Circulating B-cells decreased to undetectable levels (< 1 cell/microliter) by Cycle 1 Day 15 after administration of the recommended dosage of MONJUVI in patients with FL who had detectable B-cells at treatment initiation and the depletion was sustained while patients remained on treatment.
Pharmacokinetic (PK) parameters are presented as geometric mean (CV%) unless otherwise specified.
Tafasitamab-cxix maximum concentration is achieved at the end of weekly dosing (i.e., end of Cycle 3). PK exposures are summarized for the recommended dosage of MONJUVI in Table 8.

Elimination
Tafasitamab-cxix estimated elimination half-life was 13.4 days (31.7%) with an apparent clearance of 0.44 L/day (29.2%).
Specific Populations
Body weight (37.6 to 163 kg) has a significant effect on the PK of tafasitamab‑cxix, with higher clearance and volume of distribution expected with higher body weight. No clinically meaningful differences in the PK of tafasitamab-cxix were observed based on age (16 to 90 years), sex, race (Asian versus non-Asian), mild to severe renal impairment (creatinine clearance [CLcr] 15 to < 90 mL/min as estimated by Cockcroft-Gault formula), and mild to moderate hepatic impairment (total bilirubin ≤ ULN and AST > ULN, or total bilirubin 1 to 3.0 times ULN and any AST).
The effect of end-stage renal disease (CLcr < 15 mL/min) and severe hepatic impairment (total bilirubin > 3.0 times ULN and any AST) on the PK of tafasitamab-cxix are unknown.
Drug Interaction Studies
No clinical studies evaluating the drug interaction potential of tafasitamab-cxix have been conducted. In population PK analyses, no clinically meaningful differences in tafasitamab-cxix PK were observed when used concomitantly with lenalidomide and with the combination of lenalidomide and rituximab.
The observed incidence of anti-drug antibodies (ADA) is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude clinically meaningful comparisons of the incidence of ADA in the studies described below with the incidence of ADA in other studies, including those of MONJUVI or other tasfasitamab products.
Following MONJUVI treatment, anti-tafasitamab-cxix antibodies developed in 2.5% (2/81) of patients with DLBCL in Study L-MIND (up to 23 cycles) and 0.9% (3/327) of patients with FL in Study inMIND (up to 12 cycles) [see Clinical Studies (14.1, 14.2)]. Because of the low occurrence of ADA, the effect of these antibodies on the pharmacokinetics, pharmacodynamics, safety, and effectiveness of tasfasitamab products is unknown.
Carcinogenicity and genotoxicity studies have not been conducted with tafasitamab-cxix.
Fertility studies have not been conducted with tafasitamab-cxix.
In the 13-week repeat-dose general toxicity study in cynomolgus monkeys, no adverse effects on male and female reproductive organs were observed up to the highest dose tested, 100 mg/kg/week (approximately 9 times the human exposure based on AUC at the clinical dose of 12 mg/kg/week).
The efficacy of MONJUVI in combination with lenalidomide followed by MONJUVI as monotherapy was evaluated in L-MIND, an open-label, multicenter, single arm trial (NCT02399085). Eligible patients had relapsed or refractory DLBCL after 1 to 3 prior systemic therapies, including a CD20-directed cytolytic antibody, and were not candidates for high dose chemotherapy (HDC) followed by autologous stem cell transplantation (ASCT). Patients received MONJUVI 12 mg/kg intravenously in combination with lenalidomide (25 mg orally on Days 1 to 21 of each 28-day cycle) for a maximum of 12 cycles, followed by MONJUVI as monotherapy until disease progression or unacceptable toxicity as follows:
Of the 71 patients with DLBCL confirmed by central laboratory who received the combination therapy, the median age was 71 years (range: 41 to 86 years); 55% were males, and 100% had received a prior CD20-containing therapy. Race was collected in 92% of patients; of these, 95% were White, and 3% were Asian. The median number of prior therapies was 2; 49% had 1 prior line of treatment, and 51% had 2 to 4 prior lines. Thirty-two patients (45%) were refractory to their last prior therapy and 30 (42%) were refractory to rituximab. Nine patients (13%) had received prior ASCT. The primary reasons patients were not candidates for ASCT included age (47%), refractoriness to salvage chemotherapy (27%), comorbidities (13%) and refusal of high dose chemotherapy/ASCT (13%).
Efficacy was established based on best overall response rate, defined as the proportion of complete and partial responders, and duration of response, as assessed by an Independent Review Committee using the International Working Group Response Criteria (Cheson, 2007). Results are summarized in Table 9.

The efficacy of MONJUVI in combination with lenalidomide and rituximab in patients with relapsed or refractory FL was evaluated in inMIND, a randomized, double-blind, placebo‑controlled trial (NCT04680052). The study enrolled a total of 548 patients with relapsed or refractory FL Grade 1, 2, or 3a after at least 1 systemic therapy, including an anti-CD20 antibody.
Patients were randomized in a 1:1 ratio to receive MONJUVI or placebo in combination with lenalidomide and rituximab. Randomization was stratified by progression of disease within 24 months after initial diagnosis (POD24) (yes versus no), refractoriness to prior CD20-directed antibody therapy (yes versus no), and the number of prior lines of systemic therapy (< 2 versus ≥ 2). Treatment was administered in 28-day cycles as follows:
Patients on the control arm received the same regimen, but with placebo in lieu of MONJUVI.
Of all patients with FL randomized, the median age was 64 years (range: 31-88 years), with 20% being age 75 or older; 55% were male; 80% were White, 15% Asian, and 0.2% were Black. The median number of prior lines of systemic therapy was 1 (range 1-10) with 55% receiving 1 prior line, 25% receiving 2 prior lines, and 20% receiving 3 or more prior lines. In total, 32% had POD24 and 43% had refractory disease to prior CD20-directed therapy.
The major efficacy outcome measure was investigator-assessed progression‑free survival (PFS) using the Lugano criteria. Efficacy results are summarized in Table 10 and Figure 1. The median duration of PFS follow-up was 14.1 months.

Figure 1: Kaplan-Meier Curve for PFS by Investigator Assessment in inMIND
At the time of the PFS analysis, the median overall survival had not been reached in either arm with a total of 38 deaths: 15 deaths (5.5%) in the MONJUVI arm and 23 deaths (8.4%) in the placebo arm.
Lack of efficacy in patients with relapsed or refractory marginal zone lymphoma (MZL) was observed in the inMIND trial (NCT04680052), a prospective, randomized clinical trial in which a cohort of 106 patients with relapsed or refractory MZL were randomized 1:1 to receive MONJUVI or placebo in combination with lenalidomide and rituximab. There was no evidence of improvement in investigator-assessed PFS in the MONJUVI arm.
At the time of the PFS analysis, the median overall survival had not been reached in either arm with a total of 8 deaths: 7 deaths (13.2%) in the MONJUVI arm and 1 death (1.9%) in the placebo arm.
MONJUVI is not indicated and is not recommended for the treatment of patients with relapsed or refractory MZL outside of controlled clinical trials.
