Warnings and precautions
Myelosuppression : Delay or reduce dose, and restart treatment based on ANC and platelet count recovery. ( 5.1 )
Infections : Monitor for fever and other signs of infection or reactivation of infections and treat promptly. ( 5.2 )
Progressive multifocal leukoencephalopathy (PML) : Monitor for new or worsening neurological, cognitive or behavioral signs or symptoms suggestive of PML. ( 5.3 )
Anaphylaxis and Infusion-Related Reactions : Severe anaphylactic reactions have occurred. Monitor clinically and discontinue drug for severe reactions. Pre-medicate in subsequent cycles for milder reactions. ( 5.4 )
Tumor Lysis Syndrome : May lead to acute renal failure and death; anticipate and use supportive measures in patients at high risk. ( 5.5 )
Skin Reactions : Discontinue for severe skin reactions. Cases of SJS, DRESS and TEN, some fatal, have been reported. ( 5.6 ).
Hepatotoxicity : Monitor liver chemistry tests prior to and during treatment. ( 5.7 )
Other Malignancies : Pre-malignant and malignant diseases have been reported. ( 5.8 )
Extravasation Injury : Take precautions to avoid extravasation, including monitoring intravenous infusion site during and after administration. ( 5.9 )
Embryo-Fetal Toxicity : Can cause fetal harm. Advise females of reproductive potential and males with female partners of reproductive potential of the potential risk to a fetus and to use an effective method of contraception. ( 5.10 , 8.1 , 8.3 )
5.1Myelosuppression
VIVIMUSTA causes myelosuppression. Bendamustine hydrochloride caused severe myelosuppression (Grade 3-4) in 98% of patients in the two NHL studies [see Adverse Reactions ( 6.1 )] . Three patients (2%) died from myelosuppression-related adverse reactions; one each from neutropenic sepsis, diffuse alveolar hemorrhage with Grade 3 thrombocytopenia and pneumonia from an opportunistic infection (CMV). Monitor complete blood counts, including leukocytes, platelets, hemoglobin (Hgb), and neutrophils frequently.
In the clinical trials, blood counts were monitored every week initially. Hematologic nadirs were observed predominantly in the third week of therapy. Myelosuppression may require dose delays and/or subsequent dose reductions if recovery to the recommended values has not occurred by the first day of the next scheduled cycle. Delay the next cycle of therapy if ANC less than 1 x 10 9 /L or platelet count less than 75 x 10 9 /L [see Dosage and Administration ( 2.1 , 2.2 )].
5.2Infections
Infection, including pneumonia, sepsis, septic shock, hepatitis and death has occurred in adult and pediatric patients in clinical trials and in postmarketing reports for bendamustine hydrochloride [ see Adverse Reactions ( 6.1 , 6.2 ) ]. Patients with myelosuppression following treatment with bendamustine hydrochloride are more susceptible to infections. Advise patients with myelosuppression following VIVIMUSTA treatment to contact healthcare provider immediately if they have symptoms or signs of infection.
Patients treated with VIVIMUSTA are at risk for reactivation of infections including (but not limited to) hepatitis B, cytomegalovirus, Mycobacterium tuberculosis, and herpes zoster. Implement appropriate measures (including clinical and laboratory monitoring, prophylaxis, and treatment) for infection and infection reactivation prior to administration.
Progressive multifocal leukoencephalopathy (PML), including fatal cases, have occurred following treatment with bendamustine, primarily in combination with rituximab or obinutuzumab [see Adverse Reactions ( 6.2 )] . Consider PML in the differential diagnosis in patients with new or worsening neurological, cognitive or behavioral signs or symptoms. If PML is suspected, withhold VIVIMUSTA treatment and perform appropriate diagnostic evaluations.
Consider discontinuation or reduction of any concomitant chemotherapy or immunosuppressive therapy in patients who develop PML.
5.4Anaphylaxis and Infusion-Related Reactions
Infusion-related reactions to bendamustine hydrochloride have occurred commonly in clinical trials. Symptoms include fever, chills, pruritus and rash. In rare instances, severe anaphylactic and anaphylactoid reactions have occurred, particularly in the second and subsequent cycles of therapy. Monitor clinically and discontinue drug for severe reactions. Ask patients about symptoms suggestive of infusion-related reactions after their first cycle of therapy.
Do not rechallenge patients who experienced Grade 3 or worse allergic-type reactions. Consider measures to prevent severe reactions, including antihistamines, antipyretics and corticosteroids in subsequent cycles in patients who have experienced Grade 1 or 2 infusion-related reactions. Discontinue VIVIMUSTA for patients with Grade 4 infusion-related reactions. Consider discontinuation for Grade 3 infusion-related reactions as clinically appropriate considering individual benefits, risks, and supportive care.
5.5Tumor Lysis Syndrome
Tumor lysis syndrome associated with bendamustine hydrochloride has occurred in patients in clinical trials and in postmarketing reports. The onset tends to be within the first treatment cycle of bendamustine hydrochloride and, without intervention, may lead to acute renal failure and death. Administer vigorous hydration and monitor blood chemistry, particularly potassium and uric acid levels at baseline and closely during treatment with VIVIMUSTA.
Allopurinol has also been used during the beginning of bendamustine hydrochloride therapy. However, there may be an increased risk of severe skin toxicity when bendamustine hydrochloride and allopurinol are administered concomitantly [see Warnings and Precautions ( 5.6 )].
5.6Skin Reactions Fatal
and serious skin reactions have been reported with bendamustine hydrochloride treatment in clinical trials and postmarketing safety reports, including toxic skin reactions [Stevens-Johnson Syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS)], bullous exanthema, and rash. Events occurred when bendamustine hydrochloride was given as a single agent and in combination with other anticancer agents or allopurinol.
Where skin reactions occur, they may be progressive and increase in severity with further treatment. Monitor patients with skin reactions closely. If skin reactions are severe or progressive, withhold or discontinue VIVIMUSTA.
5.7Hepatotoxicity Fatal
and serious cases of liver injury have been reported with Bendamustine Hydrochloride Injection [see Adverse Reactions ( 6.1 )]. Combination therapy, progressive disease or reactivation of hepatitis B were confounding factors in some patients [see Warnings and Precautions ( 5.2 )]. Most cases were reported within the first three months of starting therapy. Monitor liver chemistry tests prior to and during treatment with VIVIMUSTA.
5.8Other Malignancies Pre-malignant
and malignant diseases have developed in patients who have been treated with bendamustine hydrochloride, including myelodysplastic syndrome, myeloproliferative disorders, acute myeloid leukemia, bronchial carcinoma, and non-melanoma skin cancer including basal cell carcinoma and squamous cell carcinoma [see Adverse Reactions ( 6.2 )] . Monitor patients for the development of secondary malignancies. Perform dermatologic evaluations during and after treatment with VIVIMUSTA.
5.9Extravasation Injury
Bendamustine hydrochloride extravasations have been reported in postmarketing resulting in hospitalizations from erythema, marked swelling, and pain. Assure good venous access prior to starting VIVIMUSTA infusion and monitor the intravenous infusion site for redness, swelling, pain, infection, and necrosis during and after administration of VIVIMUSTA.

Interactions
Consider alternative therapies that are not CYP1A2 inducers or inhibitors during treatment with VIVIMUSTA. ( 7.1 )
7.1Effect of Other Drugs on
VIVIMUSTA CYP1A2 Inhibitors The coadministration of VIVIMUSTA with CYP1A2 inhibitors may increase bendamustine plasma concentrations and may result in increased incidence of adverse reactions with VIVIMUSTA [see Clinical Pharmacology ( 12.3 )]. Consider alternative therapies that are not CYP1A2 inhibitors during treatment with VIVIMUSTA. CYP1A2 Inducers The coadministration of VIVIMUSTA with CYP1A2 inducers may decrease bendamustine plasma concentrations and may result in decreased efficacy of VIVIMUSTA [see Clinical Pharmacology ( 12.3 )].
Consider alternative therapies that are not CYP1A2 inducers during treatment with VIVIMUSTA.
Pregnancy and breastfeeding
8.1Pregnancy Risk Summary
In animal reproduction studies, intraperitoneal administration of bendamustine to pregnant mice and rats during organogenesis at doses 0.6 to 1.8 times the maximum recommended human dose (MRHD) resulted in embryo-fetal and/or infant mortality, structural abnormalities, and alterations to growth (see Data). There are no available data on bendamustine hydrochloride use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes.
Advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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.
Data Animal Data Bendamustine hydrochloride was intraperitoneally administered once to mice from 210 mg/m 2 (approximately 1.8 times the MRHD) during organogenesis and caused an increase in resorptions, skeletal and visceral malformations (exencephaly, cleft palates, accessory rib, and spinal deformities) and decreased fetal body weights. This dose did not appear to be maternally toxic and lower doses were not evaluated.
Repeat intraperitoneal administration of bendamustine hydrochloride in mice on gestation days 7 to 11 resulted in an increase in resorptions from 75 mg/m 2 (approximately 0.6 times the MRHD) and an increase in abnormalities from 112.5 mg/m 2 (approximately 0.9 times the MRHD), similar to those seen after a single intraperitoneal administration. Bendamustine hydrochloride was intraperitoneally administered once to rats from 120 mg/m 2 (approximately the MRHD) on gestation days 4, 7, 9, 11, or 13 and caused embryo and fetal lethality as indicated by increased resorptions and a decrease in live fetuses.
A significant increase in external (effect on tail, head, and herniation of external organs [exomphalos]) and internal (hydronephrosis and hydrocephalus) malformations were seen in dosed rats.

6.1Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Chronic Lymphocytic Leukemia (CLL) The data described below reflect exposure to bendamustine hydrochloride in 153 patients. Bendamustine hydrochloride was studied in an active-controlled, randomized trial.
The population was 45-77 years of age, 63% were male, 100% were White, and had treatment naïve CLL. All patients started the study at a dose of 100 mg/m2 intravenously over 30 minutes on Days 1 and 2 every 28 days. Adverse reactions were reported according to NCI CTC v.2.0. In the randomized CLL clinical study, non-hematologic adverse reactions (any grade) in the bendamustine hydrochloride group that occurred with a frequency greater than 15% were pyrexia (24%), nausea (20%), and vomiting (16%).
Other adverse reactions seen frequently in one or more studies included asthenia, fatigue, malaise, and weakness; dry mouth; somnolence; cough; constipation; headache; mucosal inflammation and stomatitis. Worsening hypertension was reported in 4 patients treated with bendamustine hydrochloride and in none treated with chlorambucil. Three of these 4 adverse reactions were described as a hypertensive crisis and were managed with oral medications and resolved.
The most frequent adverse reactions leading to study withdrawal for patients receiving bendamustine hydrochloride were hypersensitivity (2%) and pyrexia (1%). Table 2 summarizes the adverse reactions that were reported in ≥ 5% of patients in either treatment group in the randomized CLL clinical study. Table 2: Non-Hematologic Adverse Reactions that Occurred in at Least 5% of Patients Who Received Bendamustine Hydrochloride or Chlorambucil in the Randomized CLL Clinical Study Adverse Reaction Bendamustine Hydrochloride (N=153) Chlorambucil (N=143) All Grades n (%) Grade 3 or 4 n (%) All Grades n (%) Grade 3 or 4 n (%) Total number of patients with at least 1 adverse reaction 121 (79) 52 (34) 96 (67) 25 (17) Gastrointestinal disorders Nausea 31 (20) 1 (<1) 21 (15) 1 (<1) Vomiting 24 (16) 1 (<1) 9 (6) 0 Diarrhea 14 (9) 2 (1) 5 (3) 0 General disorders and administration site conditions Pyrexia 36 (24) 6 (4) 8 (6) 2 (1) Fatigue 14 (9) 2 (1) 8 (6) 0 Asthenia 13 (8) 0 6 (4) 0 Chills 9 (6) 0 1 (<1) 0 Immune system disorders Hypersensitivity 7 (5) 2 (1) 3 (2) 0 Infections and infestations Nasopharyngitis 10 (7) 0 12 (8) 0 Infection 9 (6) 3 (2) 1 (<1) 1 (<1) Herpes simplex 5 (3) 0 7 (5) 0 Investigations Weight decreased 11 (7) 0 5 (3) 0 Metabolism and nutrition disorders Hyperuricemia 11 (7) 3 (2) 2 (1) 0 Respiratory, thoracic and mediastinal disorders Cough 6 (4) 1 (<1) 7 (5) 1 (<1) Skin and subcutaneous tissue disorders Rash 12 (8) 4 (3) 7 (5) 3 (2) Pruritus 8 (5) 0 2 (1) 0 Hematology laboratory abnormalities are described in Table 3.
Red blood cell transfusions were administered to 20% of patients receiving bendamustine hydrochloride compared with 6% of patients receiving chlorambucil. Bilirubin elevation occurred in 34% of patients, some without associated significant elevations in AST and ALT. Grade 3 or 4 increased bilirubin occurred in 3% of patients. Increases in AST and ALT of Grade 3 or 4 were limited to 1% and 3% of patients, respectively.
Patients treated with bendamustine hydrochloride may also have changes in their creatinine levels.

The population was 31-84 years of age; 60% were male; 89% were White, 7% were Black, 3% were Hispanic, 1% were other, and <1% were Asian. These patients received bendamustine hydrochloride at a dose of 120 mg/m 2 intravenously on Days 1 and 2 for up to eight 21-day cycles. In both studies, serious adverse reactions, were reported in 37% of patients receiving bendamustine hydrochloride. The most frequent serious adverse reactions occurring in ≥5% of patients were febrile neutropenia and pneumonia.
Other important serious adverse reactions reported in clinical trials and/or postmarketing experience were acute renal failure, cardiac failure, hypersensitivity, skin reactions, pulmonary fibrosis, and myelodysplastic syndrome. Serious adverse reactions reported in clinical trials included myelosuppression, infection, pneumonia, tumor lysis syndrome and infusion-related reactions [see Warnings and Precautions ( 5 )].
Adverse reactions occurring less frequently but possibly related to bendamustine hydrochloride treatment were hemolysis, dysgeusia/taste disorder, atypical pneumonia, sepsis, herpes zoster, erythema, dermatitis, and skin necrosis. The most common non-hematologic adverse reactions (≥30%) were nausea (75%), fatigue (57%), vomiting (40%), diarrhea (37%) and pyrexia (34%). The most common non-hematologic Grade 3 or 4 adverse reactions (≥5%) were fatigue (11%), febrile neutropenia (6%), and pneumonia, hypokalemia and dehydration, each reported in 5% of patients.
Non-hematologic adverse reactions are shown in Table 4.
