`
`2.3 Preparation for Intravenous Administration
`BENDEKA is a hazardous drug. Follow applicable special handling and disposal procedures.1
`
`
` BENDEKA is in a multiple-dose vial. At room temperature, BENDEKA is a clear, and colorless to yellow ready-to-dilute solution.
` Store BENDEKA at recommended refrigerated storage conditions (2°C to 8°C or 36°F to 46°F). When refrigerated, the contents may
`
`
` freeze. Allow the vial to reach room temperature (15°C to 30°C or 59°F to 86°F) prior to use. Do not use the product if particulate
`matter is observed after achieving room temperature.
`Intravenous Infusion
` Aseptically withdraw the volume needed for the required dose from the 25 mg/mL solution as per Table A below and immediately
`
`transfer the solution to a 50 mL infusion bag of one of the following diluents:
`
` 0.9% Sodium Chloride Injection, USP; or
`
` 2.5% Dextrose/0.45% Sodium Chloride Injection, USP; or
`
` 5% Dextrose Injection, USP.
`The resulting final concentration of bendamustine hydrochloride in the infusion bag should be within 0.49 mg/mL to 5.6 mg/mL. After
`transferring, thoroughly mix the contents of the infusion bag. The admixture should be a clear, and colorless to yellow solution.

`Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever
` solution and container permit. Any unused solution should be discarded according to institutional procedures for antineoplastics.
`
`
`2.4 Admixture Stability
`BENDEKA contains no antimicrobial preservative. Prepare the admixture as close as possible to the time of patient administration.
`If diluted with 0.9% Sodium Chloride Injection, USP, or 2.5% Dextrose/0.45% Sodium Chloride Injection, USP, the final admixture is
`
`stable for 24 hours when stored refrigerated (2°C to 8°C or 36°F to 46°F) or for 6 hours when stored at room temperature (15°C to
`30°C or 59°F to 86°F) and room light. Administration of diluted BENDEKA (bendamustine hydrochloride) injection must be
`completed within this period of time.
`In the event that 5% Dextrose Injection, USP is utilized, the final admixture is stable for 24 hours when stored refrigerated (2°C to 8°C
`or 36°F to 46°F) or for only 3 hours when stored at room temperature (15°C to 30°C or 59°F to 86°F) and room light. Administration
`of diluted BENDEKA must be completed within this period of time.
`Retain the partially used vial in original package to protect from light and store refrigerated (2°C to 8°C or 36°F to 46°F) if additional
`dose withdrawal from the same vial is intended.
`
`
`2.5 Stability of Partially Used Vials (Needle Punched Vials)
`BENDEKA is supplied in a multiple-dose vial. Although it does not contain any antimicrobial preservative, BENDEKA is
`
`bacteriostatic. The partially used vials are stable for up to 28 days when stored in its original carton under refrigeration (2°C to 8°C or
`36°F to 46°F). Each vial is not recommended for more than a total of six (6) dose withdrawals.
`After first use, store the partially used vial in the refrigerator in the original carton at 2°C to 8°C or 36°F to 46°F and then discard after
`28 days.
`
`3 DOSAGE FORMS AND STRENGTHS
`Injection: 100 mg/4 mL (25 mg/mL) as a clear and colorless to yellow ready-to-dilute solution in a multiple-dose vial.
`
`
`4 CONTRAINDICATIONS
`BENDEKA is contraindicated in patients with a known hypersensitivity (e.g., anaphylactic and anaphylactoid reactions) to
`bendamustine, polyethylene glycol 400, propylene glycol, or monothioglycerol. [see Warnings and Precautions (5.4)]
`
`5
`
`Reference ID: 4871635
`
`
`
`5 WARNINGS AND PRECAUTIONS
`
` 5.1 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).
`BENDEKA causes myelosuppression. 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 occurred
`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. Prior to the initiation of the next cycle of
`
` therapy, the ANC should be ≥ 1 x 109/L and the platelet count should be ≥ 75 x 109/L. [see Dosage and Administration (2.1)
`
`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 [see Adverse Reactions (6.1)]. Patients with myelosuppression
`following treatment with bendamustine hydrochloride are more susceptible to infections. Advise patients with myelosuppression
`following BENDEKA treatment to contact a physician immediately if they have symptoms or signs of infection.
`Patients treated with BENDEKA are at risk for reactivation of infections including (but not limited to) hepatitis B, cytomegalovirus,
`
`Mycobacterium tuberculosis, and herpes zoster. Patients should undergo 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 BENDEKA
`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 Reactions
`Infusion reactions to bendamustine hydrochloride have occurred commonly in clinical trials [see Adverse Reactions (6.1)]. 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
`
`6
`
`Reference ID: 4871635
`
`
`
`symptoms suggestive of infusion reactions after their first cycle of therapy. Patients who experienced Grade 3 or worse allergic-type
`reactions were not typically rechallenged. Consider measures to prevent severe reactions, including antihistamines, antipyretics and
`
` corticosteroids in subsequent cycles in patients who have experienced Grade 1 or 2 infusion reactions. Discontinue BENDEKA for
`patients with Grade 4 infusion reactions. Consider discontinuation for Grade 3 infusion 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 [see Adverse Reactions (6.1)]. The onset tends to be within the first treatment cycle of bendamustine hydrochloride and,
`without intervention, may lead to acute renal failure and death. Preventive measures include vigorous hydration and close monitoring
`of blood chemistry, particularly potassium and uric acid levels. 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)]
`
`5.6 Skin Reactions
`
`Fatal and serious skin reactions have been reported with bendamustine hydrochloride injection 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 [see Adverse Reactions (6.1 and
`
`6.2)]. Events occurred when bendamustine hydrochloride injection 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 BENDEKA.
`
`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
`BENDEKA therapy.
`
`5.8 Other Malignancies
`There are reports of pre-malignant and malignant diseases that 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)].
`
`
`7
`
`Reference ID: 4871635
`
`
`
`Monitor patients for the development of secondary malignancies. Perform dermatologic evaluations during and after treatment with
`
` BENDEKA.
`
`5.9 Extravasation Injury
`Bendamustine hydrochloride extravasations have been reported in postmarketing resulting in hospitalizations from erythema, marked
`swelling, and pain [see Adverse Reactions (6.2)]. Assure good venous access prior to starting drug infusion and monitor the
`intravenous infusion site for redness, swelling, pain, infection, and necrosis during and after administration of BENDEKA.
`
`5.10 Embryo-Fetal Toxicity
`Based on findings from animal reproduction studies and the drug’s mechanism of action, BENDEKA 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 BENDEKA and for 6 months after the last dose. Advise males with female partners of reproductive potential to use effective
`contraception during treatment with BENDEKA and for 3 months after the last dose. [see Use in Specific Populations (8.1, 8.3) and
`
`Clinical Pharmacology (12.1)]
`
`6 ADVERSE REACTIONS
`The following clinically significant adverse reactions have been associated with bendamustine hydrochloride in clinical trials and are
`discussed in greater detail in other sections of the prescribing information.
`
`
` Myelosuppression [see Warnings and Precautions (5.1)]

`
`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.
`The data described below reflect exposure to bendamustine hydrochloride in 329 patients who participated in an actively controlled
` trial (N=153) for the treatment of CLL and two single arm studies (N=176) for the treatment of indolent B cell NHL. 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.
`The safety of BENDEKA administered IV as a 50 mL admixture over a 10-minute infusion is supported by clinical trials using
`bendamustine hydrochloride administered IV as a 500 mL admixture over 30-60 minutes infusion time, as well as an open-label,
`crossover study in 81 ‘end-of-life’ cancer patients treated with BENDEKA. In total, safety data from clinical studies are available
`from over 400 cancer patients exposed to bendamustine hydrochloride at doses in the range used in the treatment of CLL and NHL.
`No clinically significant differences in the adverse reaction profile were noted among bendamustine hydrochloride administered as a
`500 mL admixture over standard infusion time (30-60 minutes) and BENDEKA administered as a 50 mL admixture in a ‘short-time’
`infusion over 10 minutes.
`The safety and tolerability of BENDEKA was evaluated in an 8-week clinical study of BENDEKA in 81 ‘end-of-life’ cancer patients,
`
`diagnosed with solid tumors and hematologic malignancies (excluding CLL). The population was 40-82 years of age, 58% females,
`84% white, 12.3% Black, 1.2% Asian and 2.5% were classified as ‘other’. BENDEKA was administered IV at a 120 mg/m2 dose as a
`50 mL admixture over 10 minutes. Patients in the study received BENDEKA (50 mL IV, over 10 minutes) or bendamustine
`hydrochloride (500 mL IV, over 60 minutes) on Days 1 and 2 every 28 days for two consecutive 2-day cycles.
`Adverse reactions (any grade) that occurred with a frequency greater than 5% during BENDEKA infusion and within one hour post-
`infusion were nausea (8.2%) and fatigue (5.5%).
`Adverse reactions (any grade) that occurred with a frequency greater than 5% within 24 hours of BENDEKA were nausea (10.9%)
`and fatigue (8.2%).
`Adverse reactions leading to study withdrawal in 4 patients receiving BENDEKA were pyrexia (1.2%), nausea (1.2%), vomiting
`(1.2%), pneumonia (1.2%) and fatigue (1.2%).

`
`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% male, 100% 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 in the randomized CLL clinical study 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 1 contains the treatment emergent adverse reactions, regardless of attribution, that were reported in ≥ 5% of patients in either
`treatment group in the randomized CLL clinical study.

`The Grade 3 and 4 hematology laboratory test values by treatment group in the randomized CLL clinical study are described in Table
`2. These findings confirm the myelosuppressive effects seen in patients treated with bendamustine hydrochloride. Red blood cell
`transfusions were administered to 20% of patients receiving bendamustine hydrochloride compared with 6% of patients receiving
`chlorambucil.

`In the randomized CLL trial, 34% of patients had bilirubin elevations, 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. If
`abnormalities are detected, monitoring of these parameters should be continued to ensure that significant deterioration does not occur.
`
`
`Non-Hodgkin’s 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% male, and 40% female. The race distribution was 89% White, 7%
`
`Black, 3% Hispanic, 1% other, and <1% 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.
`The adverse reactions occurring in at least 5% of the NHL patients, regardless of severity, are shown in Table 3. 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.
