4 Contraindications
VIVIMUSTA is contraindicated in patients with a known hypersensitivity (e.g., anaphylactic and anaphylactoid reactions) to bendamustine, polyethylene glycol 400, dehydrated alcohol, or monothioglycerol [see Warnings and Precautions (5.4)]
History of a hypersensitivity reaction to bendamustine, polyethylene glycol 400, dehydrated alcohol, or monothioglycerol. Reactions to bendamustine hydrochloride have included anaphylaxis and anaphylactoid reactions. (4, 5.4)
5 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)
5.1 Myelosuppression
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 109/L or platelet count less than 75 x 109/L [see Dosage and Administration (2.1, 2.2)].
5.2 Infections
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. 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.
5.3 Progressive Multifocal Leukoencephalopathy (PML)
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.
5.4 Anaphylaxis 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.
5.5 Tumor 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 (5.5)].
5.6 Skin 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.
5.7 Hepatotoxicity
Fatal and serious cases of liver injury have been reported with bendamustine hydrochloride injection. 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.
5.8 Other 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.
5.9 Extravasation 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.
5.10 Embryo-Fetal Toxicity
Based on findings from animal reproduction studies and the drug's mechanism of action, VIVIMUSTA can cause fetal harm when administered to a pregnant woman. Single intraperitoneal doses of bendamustine (that approximated the maximum recommended human dose based on body surface area) to pregnant mice and rats during organogenesis caused adverse developmental outcomes, including an increase in resorptions, skeletal and visceral malformations, and decreased fetal body weights. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use an effective method of contraception during treatment with VIVIMUSTA and for 6 months after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with VIVIMUSTA and for 3 months after the last dose [see Use in Specific Populations (8.1, 8.3) and Clinical Pharmacology (12.1)].

6.1 Clinical 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.

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.

Non-Hodgkin Lymphoma (NHL)
The data described below reflect exposure to bendamustine hydrochloride in 176 patients with indolent B-cell NHL treated in two single-arm studies. 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/m2 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.

7 Drug Interactions
Consider alternative therapies that are not CYP1A2 inducers or inhibitors during treatment with VIVIMUSTA. (7.1)
7.1 Effect 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.
8 Use In Specific Populations
• Lactation: Advise not to breastfeed. (8.2) • Infertility: May impair fertility. (8.3) • Renal Impairment: Do not use in patients with creatinine clearance < 30 mL/min. (8.6) • Hepatic Impairment: Do not use in patients with total bilirubin 1.5-3 x ULN and AST or ALT 2.5-1.0 x ULN, or total bilirubin > 3 x ULN. (8.7)
8.1 Pregnancy
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/m2 (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/m2 (approximately 0.6 times the MRHD) and an increase in abnormalities from 112.5 mg/m2 (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/m2 (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.
8.2 Lactation
Risk Summary There are no data on the presence of bendamustine hydrochloride or its metabolites in either human or animal milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in the breastfed child, advise women not to breastfeed during treatment with VIVIMUSTA and for 1 week after the last dose.
8.3 Females and Males of Reproductive Potential
VIVIMUSTA can cause embryo-fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)].
Pregnancy Testing Pregnancy testing is recommended for females of reproductive potential prior to initiation of treatment with VIVIMUSTA.
Contraception
Females Advise female patients of reproductive potential to use effective contraception during treatment with VIVIMUSTA and for 6 months after the last dose. Males Based on genotoxicity findings, advise males with female partners of reproductive potential to use effective contraception during treatment with VIVIMUSTA and for 3 months after the last dose [see Nonclinical Toxicology (13.1)]. Infertility Based on findings from clinical studies, VIVIMUSTA may impair male fertility. Impaired spermatogenesis, azoospermia, and total germinal aplasia have been reported in male patients treated with alkylating agents, especially in combination with other drugs. In some instances spermatogenesis may return in patients in remission, but this may occur only several years after intensive chemotherapy has been discontinued. Advise patients of the potential risk to their reproductive capacities. Based on findings from animal studies, VIVIMUSTA may impair male fertility due to an increase in morphologically abnormal spermatozoa. The long-term effects of VIVIMUSTA on male fertility, including the reversibility of adverse effects, have not been studied [see Nonclinical Toxicology (13.1)].
8.4 Pediatric Use
Safety and effectiveness in pediatric patients have not been established. Safety, pharmacokinetics and efficacy were assessed in a single open-label trial (NCT01088984) in patients aged 1-19 years with relapsed or refractory acute leukemia, including 27 patients with acute lymphocytic leukemia (ALL) and 16 patients with acute myeloid leukemia (AML). Bendamustine hydrochloride was administered as an intravenous infusion over 60 minutes on Days 1 and 2 of each 21-day cycle. There was no treatment response (CR+ CRp) in any patient. The safety profile in these patients was consistent with that seen in adults and no new safety signals were identified. The pharmacokinetics of bendamustine in 43 patients, aged 1 to 19 years (median age of 10 years) were within range of values previously observed in adults given the same dose based on body surface area.
8.5 Geriatric Use
No overall differences in safety were observed between patients ≥65 years of age and younger patients. Efficacy was lower in patients 65 and over with CLL receiving bendamustine hydrochloride based upon an overall response rate of 47% for patients 65 and over and 70% for younger patients. Progression free survival was also longer in younger patients with CLL receiving bendamustine (19 months vs. 12 months). No overall differences in efficacy in patients with non-Hodgkin Lymphoma were observed between geriatric patients and younger patients.
8.6 Renal Impairment
Do not use VIVIMUSTA in patients with creatinine clearance (CLcr) less than 30 mL/min [see Clinical Pharmacology (12.3)].
8.7 Hepatic Impairment
Do not use VIVIMUSTA in patients with AST or ALT 2.5 to 10 times upper limit of normal (ULN) and total bilirubin 1.5 to 3 times ULN or total bilirubin greater than 3 times ULN [see Clinical Pharmacology (12.3)]
10 Overdosage
The intravenous lethal dose 50 (LD50) of bendamustine hydrochloride is 240 mg/m2 in the mouse and rat. Toxicities included sedation, tremor, ataxia, convulsions and respiratory distress. Across all clinical experience, the reported maximum single dose received was 280 mg/m2. Three of four patients who received this dose showed ECG changes considered dose-limiting at 7 and 21 days post-dosing. These changes included QT prolongation (one patient), sinus tachycardia (one patient), ST and T wave deviations (two patients) and left anterior fascicular block (one patient). Cardiac enzymes and ejection fractions remained normal in all patients. No specific antidote for bendamustine hydrochloride overdose is known. Management of overdosage should include general supportive measures, including monitoring of hematologic parameters and ECGs.
11 Description
Bendamustine hydrochloride is an alkylating agent. The chemical name of bendamustine hydrochloride monohydrate is 5-[Bis(2-chloroethyl)-amino]-1-methyl-1H-benzimidazole-2- butanoic acid hydrochloride monohydrate. Its empirical molecular formula is C16H21Cl2N3O2 ∙ HCl.H2O and the molecular weight is 412.74. Bendamustine hydrochloride monohydrate contains a mechlorethamine group and a benzimidazole heterocyclic ring with a butyric acid substituent, and has the following structural formula:
VIVIMUSTA (bendamustine hydrochloride injection) is intended for intravenous use after dilution with either 0.9% Sodium Chloride Injection, USP or 2.5% Dextrose/0.45% Sodium Chloride Injection, USP. It is supplied as a sterile, clear, and colorless to yellow solution in a clear glass multiple-dose vial. Each millilitre contains 25 mg of bendamustine hydrochloride equivalent to 22.7 mg of bendamustine, 5 mg of monothioglycerol, 39.45 mg dehydrated alcohol, and q.s. to 1 mL polyethylene glycol 400.
12 Clinical Pharmacology
12.1 Mechanism of Action
Bendamustine is a bifunctional mechlorethamine derivative containing a purine-like benzimidazole ring. Mechlorethamine and its derivatives form electrophilic alkyl groups. These groups form covalent bonds with electron-rich nucleophilic moieties, resulting in interstrand DNA crosslinks. The bifunctional covalent linkage can lead to cell death via several pathways. Bendamustine is active against both quiescent and dividing cells. The exact mechanism of action of bendamustine remains unknown.
12.2 Pharmacodynamics
Based on the pharmacokinetics/pharmacodynamics analyses of data from adult patients with NHL, nausea increased with increasing bendamustine maximum concentrations (Cmax). Cardiac Electrophysiology The effect of bendamustine on the QTc interval was evaluated in 53 patients with indolent NHL and mantle cell lymphoma on Day 1 of Cycle 1 after administration of rituximab at 375 mg/m2 intravenous infusion followed by a 30-minute intravenous infusion of bendamustine at 90 mg/m2/day. No mean changes greater than 20 milliseconds were detected up to one hour post infusion. The potential for delayed effects on the QT interval after one hour was not evaluated.
12.3 Pharmacokinetics
Absorption
Following a single IV dose of bendamustine hydrochloride Cmax typically occurred at the end of infusion. The dose proportionality of bendamustine has not been studied. Distribution The protein binding of bendamustine ranged from 94-96% and was concentration independent from 1 to 50 μg/mL. The blood to plasma concentration ratios in human blood ranged from 0.84 to 0.86 over a concentration range of 10 to 100 μg/mL. The mean steady-state volume of distribution (Vss) of bendamustine was approximately 20 to 25 L. Elimination After a single intravenous dose of 120 mg/m2 of bendamustine over 1 hour, the intermediate half-life (t½) of the parent compound was approximately 40 minutes. The mean terminal elimination t½ of two active metabolites, γ-hydroxybendamustine (M3) and N desmethylbendamustine (M4) were approximately 3 hours and 30 minutes, respectively. Bendamustine clearance in humans was approximately 700 mL/min. Metabolism Bendamustine is extensively metabolized via hydrolytic, oxidative, and conjugative pathways. Bendamustine is primarily metabolized via hydrolysis to monohydroxy (HP1) and dihydroxy-bendamustine (HP2) metabolites with low cytotoxic activity in vitro. Two active minor metabolites, M3 and M4, are primarily formed via CYP1A2 in vitro. M3 and M4 concentrations of these metabolites in plasma are 1/10th and 1/100th that of the parent compound, respectively. Excretion Following intravenous infusion of radiolabeled bendamustine hydrochloride in patients with cancer, approximately 76% of the dose was recovered. Approximately 50% of the dose was recovered in the urine (3.3% unchanged) and approximately 25% of the dose was recovered in the feces. Less than 1% of the dose was recovered in the urine as M3 and M4, and less than 5% of the dose was recovered in the urine as HP2. Specific Populations No clinically meaningful effects on the pharmacokinetics of bendamustine were observed based on age (31 to 84 years), sex, mild to moderate renal impairment (CLcr ≥ 30 mL/min), or hepatic impairment with total bilirubin 1.5 < ULN and AST or ALT < 2.5 × ULN. The effects of severe renal impairment (CLcr < 30 mL/min), or hepatic impairment with total bilirubin 1.5 to 3 × ULN and AST or ALT 2.5 to 10 × ULN or total bilirubin > 3 × ULN on the pharmacokinetics of bendamustine is unknown. Race/Ethnicity Exposures in Japanese subjects (n=6) were 40% higher than non-Japanese subjects receiving the same dose. The clinical importance of this difference on the safety and efficacy of bendamustine hydrochloride in Japanese subjects has not been established. Drug Interaction Studies

13 Nonclinical Toxicology
13.1 Carcinogenesis & Mutagenesis & Impairment Of Fertility
Bendamustine was carcinogenic in mice. After intraperitoneal injections at 37.5 mg/m2/day (the lowest dose tested, approximately 0.3 times the maximum recommended human dose [MRHD]) and 75 mg/m2/day (approximately 0.6 times the MRHD) for 4 days, peritoneal sarcomas in female AB/jena mice were produced. Oral administration at 187.5 mg/m2/day (the only dose tested, approximately 1.6 times the MRHD) for 4 days induced mammary carcinomas and pulmonary adenomas. Bendamustine is a mutagen and clastogen. In a reverse bacterial mutation assay (Ames assay), bendamustine was shown to increase revertant frequency in the absence and presence of metabolic activation. Bendamustine was clastogenic in human lymphocytes in vitro, and in rat bone marrow cells in vivo (increase in micronucleated polychromatic erythrocytes) from 37.5 mg/m2, (the lowest dose tested, approximately 0.3 times the MRHD). Bendamustine induced morphologic abnormalities in spermatozoa in mice. Following tail vein injection of bendamustine at 120 mg/m2 or a saline control on days 1 and 2 for a total of three weeks, the number of spermatozoa with morphologic abnormalities was 16% higher in the bendamustine-treated group as compared to the saline control group.
14 Clinical Studies
14.1 Chronic Lymphocytic Leukemia (CLL)
The efficacy of bendamustine hydrochloride was evaluated in an open-label, randomized, controlled multicenter trial comparing bendamustine hydrochloride to chlorambucil. The trial was conducted in 301 previously-untreated patients with Binet Stage B or C (Rai Stages I - IV) CLL requiring treatment. Need-to-treat criteria included hematopoietic insufficiency, B-symptoms, rapidly progressive disease or risk of complications from bulky lymphadenopathy. Patients with autoimmune hemolytic anemia or autoimmune thrombocytopenia, Richter’s syndrome, or transformation to prolymphocytic leukemia were excluded from the study. Patients were randomly assigned to receive either bendamustine hydrochloride 100 mg/m2 intravenously over 30 minutes on Days 1 and 2 of each 28-day cycle or chlorambucil 0.8 mg/kg (Broca’s normal weight) orally on Days 1 and 15 of each 28-day cycle. The patient populations in the bendamustine hydrochloride and chlorambucil treatment groups were balanced with regard to the following baseline characteristics: age (median 63 vs. 66 years), sex (63% vs. 61% male), Binet stage (71% vs. 69% Binet B), lymphadenopathy (79% vs. 82%), enlarged spleen (76% vs. 80%), enlarged liver (48% vs. 46%), hypercellular bone marrow (79% vs. 73%), “B” symptoms (51% vs. 53%), lymphocyte count (mean 65.7 x 109/L vs. 65.1 x 109/L), and serum lactate dehydrogenase concentration (mean 370.2 vs. 388.4 U/L). Ninety percent of patients in both treatment groups had immuno-phenotypic confirmation of CLL (CD5, CD23 and either CD19 or CD20 or both). Efficacy endpoints of objective response rate and progression-free survival were calculated using a pre-specified algorithm based on NCI working group criteria for CLL. The results of this open-label randomized study demonstrated a higher rate of overall response and a longer progression-free survival for bendamustine hydrochloride compared to chlorambucil (see Table 6). Survival data are not mature. Table 6: Efficacy Data for CLL

Figure 1. Progression-Free Survival
14.2 Non-Hodgkin Lymphoma (NHL)
The efficacy of bendamustine hydrochloride was evaluated in a single arm study of 100 patients with indolent B-cell NHL that had progressed during or within six months of treatment with rituximab or a rituximab-containing regimen. Patients were included if they relapsed within 6 months of either the first dose (monotherapy) or last dose (maintenance regimen or combination therapy) of rituximab. All patients received bendamustine hydrochloride 120 mg/m2 intravenously on Days 1 and 2 of a 21-day treatment cycle for up to 8 cycles. The median age was 60 years, 65% were male, and 95% had a baseline WHO performance status of 0 or 1. Major tumor subtypes were follicular lymphoma (62%), diffuse small lymphocytic lymphoma (21%), and marginal zone lymphoma (16%). Ninety-nine percent of patients had received previous chemotherapy, 91% of patients had received previous alkylator therapy, and 97% of patients had relapsed within 6 months of either the first dose (monotherapy) or last dose (maintenance regimen or combination therapy) of rituximab. Efficacy was based on the assessments by a blinded independent review committee (IRC) and included overall response rate (complete response + complete response unconfirmed + partial response) and duration of response (DR) as summarized in Table 7. Table 7: Efficacy Data for NHL*
