`
`2.3 Preparation for Intravenous Administration
`BENDEKA (bendamustine hydrochloride) Injection is a cytotoxic drug. Follow applicable
`special handling and disposal procedures.1
`BENDEKA is in a multiple-dose vial. BENDEKA is a clear, and colorless to yellow ready-to-
`dilute solution. Allow vial to reach room temperature. If particulate matter is observed, the
`product should not be used.
`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 1.85 mg/mL – 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.
`No other diluents have been shown to be compatible. The 5% Dextrose Injection, USP, offers a
`sodium-free method of administration for patients with certain medical conditions requiring
`restricted sodium intake.

`
`2.4 Admixture Stability
`BENDEKA (bendamustine hydrochloride) Injection contains no antimicrobial preservative. The
`admixture should be prepared 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 (2-8°C or 36-
`46°F) or for 6 hours when stored at room temperature (15-30°C or 59-86°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 (2-8°C or 36-46°F) or for only 3 hours when stored at room temperature
`(15-30°C or 59-86°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-
`8°C or 36-46°F) if additional dose withdraw 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
`
`Reference ID: 3858324
`
`4
`
`
`
`when stored in its original carton under refrigeration (2-8°C or 36-46°F). Each vial is not
`recommended for more than a total of six (6) dose withdrawals.
`After first use, the partially used vial should be stored in the refrigerator in the original carton at
`2°C to 8°C or 36-46°F and then discarded 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 (bendamustine hydrochloride) Injection 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 (5.3)]
`
`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 Table 4). 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 (bendamustine hydrochloride) Injection 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, and death have 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 BENDEKA
`(bendamustine hydrochloride) Injection treatment to contact a physician immediately if they
`have symptoms or signs of infection.
`
`5.3 Anaphylaxis and Infusion Reactions
`Infusion 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 reactions after their first cycle of therapy. Patients who
`experienced Grade 3 or worse allergic-type reactions were not typically rechallenged. Consider
`
`Reference ID: 3858324
`
`5
`
`
`
`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 (bendamustine hydrochloride) Injection for patients with Grade 4 infusion reactions.
`Consider discontinuation for Grade 3 infusion reactions as clinically appropriate considering
`individual benefits, risks, and supportive care.
`
`5.4 Tumor Lysis Syndrome
`Tumor lysis syndrome associated with bendamustine hydrochloride has occurred in patients in
`clinical trials and in post-marketing reports. The onset tends to be within the first treatment cycle
`of bendamustine hydrochloride and 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 (5.5)].
`
`5.5 Skin Reactions
`Skin reactions have been reported with bendamustine hydrochloride treatment in clinical trials
`and postmarketing safety reports, including rash, toxic skin reactions and bullous exanthema.
`Some events occurred when bendamustine hydrochloride was given in combination with other
`anticancer agents.
`In a study of bendamustine hydrochloride (90 mg/m2) in combination with rituximab, one case of
`toxic epidermal necrolysis (TEN) occurred. TEN has been reported for rituximab (see rituximab
`package insert). Cases of Stevens-Johnson syndrome (SJS) and TEN, some fatal, have been
`reported when bendamustine hydrochloride was administered concomitantly with allopurinol and
`other medications known to cause these syndromes. The relationship to bendamustine
`hydrochloride cannot be determined.
`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 (bendamustine hydrochloride) Injection.
`
`5.6 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 and bronchial carcinoma. The association
`with BENDKA (bendamustine hydrochloride) Injection therapy has not been determined.
`
`5.7 Extravasation
`Bendamustine hydrochloride extravasations have been reported in post marketing resulting in
`hospitalizations from erythema, marked swelling, and pain. 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 (bendamustine
`hydrochloride) Injection.

`
`
`
`5.8 Embryo-fetal Toxicity
`Bendamustine hydrochloride can cause fetal harm when administered to a pregnant
`woman. Single intraperitoneal doses of bendamustine in mice and rats administered during
`organogenesis caused an increase in resorptions, skeletal and visceral malformations, and
`decreased fetal body weights. [see Use in Specific Populations (8.1)]
`
`6 ADVERSE REACTIONS
`The following serious 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)]
`Infections [see Warnings and Precautions (5.2)]
`•
`• Anaphylaxis and Infusion Reactions[see Warnings and Precautions (5.3)]
`• Tumor Lysis Syndrome [see Warnings and Precautions (5.4)]
`• Skin Reactions [see Warnings and Precautions (5.5)]
`• Other Malignancies [see Warnings and Precautions (5.6)]
`• Extravasation injury [see Warnings and Precautions (5.7)]
`
`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.
`
`6.1 Adverse Events in Clinical Trials
`The safety of BENDEKA (bendamustine hydrochloride) Injection 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 event 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.
`
`Reference ID: 3858324
`
`7
`
`
`
`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%).
`The 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%).
`
`6.2 Clinical Trials Experience in CLL
`The data described below reflect exposure to bendamustine hydrochloride in 153
`patients. Bendamustine hydrochloride was studied in an active-controlled 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 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.

`6.3 Clinical Trials Experience in 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.
