5 Warnings and Precautions

5.1 Infusion-Related Reactions

Additions and/or revisions underlined:

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.

5.2 Myelosuppression

Additions and/or revisions underlined:

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 worse 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.

5.3 Infections

Additions and/or revisions underlined:

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 greater than or equal to 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 prophyaxis per institutional guidelines. Consider treatment with subcutaneous or intravenous immunoglobulin (IVIG) as appropriate.

5.4 Embryo-Fetal Toxicity

Additions and/or revisions underlined:

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.

Additions and/or revisions underlined:

. . .

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.

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.

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:

  • Cycle 1 to 3: Days 1, 8, 15, and 22 of each 28-day cycle;
  • Cycles 4 to 12: Days 1 and 15 of each 28-day cycle.

In the MONJUVI arm, 54% of patients completed all 12 cycles. The median age in that arm was 64 years (range: 36-88); 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 greater than or equal to 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%).

The most common adverse reactions (greater than or equal to 20%) in recipients of MONJUVI, excluding laboratory abnormalities, were respiratory tract infections (including COVID-19 infection and pneumonia), diarrhea, rash, fatigue, constipation, musculoskeletal pain, and cough. The most common Grade 3 or 4 laboratory abnormalities (greater than or equal to 20%) were decreased neutrophils and decreased lymphocytes.

8 Use in Specific Populations

8.1 Pregnancy

Additions and/or revisions underlined:

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.

8.5 Geriatric Use

Additions and/or revisions underlined:

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.
