`
`2.3 Preparation for Intravenous Administration
`BELRAPZO is a cytotoxic drug. Follow applicable special handling and disposal procedures.1
`
`BELRAPZO is a clear and colorless to yellow solution. Store BELRAPZO at recommended
`refrigerated storage conditions (2° to 8°C or 36° to 46°F). When refrigerated the contents may
`partially freeze. Allow the vial to reach room temperature (15° to 30°C or 59° to 86°F) prior to
`use. Observe the contents of the vial for any visible solid or particulate matter. Do not use the
`product if solid or particulate matter is observed after reaching room temperature.
`
`Intravenous Infusion
`Aseptically withdraw the volume needed for the required dose (based on 25 mg/mL
`concentration) as per Table A below and immediately transfer to a 500 mL infusion bag of 0.9%
`Sodium Chloride Injection, USP (normal saline). As an alternative to 0.9% Sodium Chloride
`Injection, USP (normal saline), a 500 mL infusion bag of 2.5% Dextrose/0.45% Sodium
`
`Chloride Injection, USP, may be considered. The resulting final concentration of
`bendamustine HCL in the infusion bag should be within 0.2 – 0.7 mg/mL. After transferring,
`thoroughly mix the contents of the infusion bag. The admixture should be a clear and colorless to
`slightly yellow solution.
`Use either 0.9% Sodium Chloride Injection, USP, or 2.5% Dextrose/0.45% Sodium
`Chloride Injection, USP, for dilution, as outlined above. No other diluents have been shown
`
`to be compatible.

`
`General Information
`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
`
`BELRAPZO contains no antimicrobial preservative. The admixture should be prepared as close
`as possible to the time of patient administration.
`
`
`Once 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 under refrigerated
`(2° to 8°C or 36° to 46°F) or for 3 hours when stored at room temperature (15° to 30°C or 59° to
`86°F) and room light. Administration of diluted BELRAPZO must be completed within this
`period of time. BELRAPZO (bendamustine hydrochloride injection) is supplied in a multiple-
`dose vial. Retain the partially used vial in original package to protect from light and store
`refrigerated (2° to 8°C or 36° to 46°F) if additional dose withdrawal from the same vial is
`intended.
`
`2.5 Stability of Partially Used Vials (Needle Punched Vials)
`BELRAPZO is supplied as a multiple-dose vial. Although it does not contain any antimicrobial
`preservative, BELRAPZO is bacteriostatic and does not support bacterial growth. The partially
`used vials are stable for up to 28 days when stored in its original carton under refrigeration (2° to
`8°C or 36° to 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 original carton at 2° to 8°C (36° to
`46°F), and then discarded after 28 days.

`
`

`

`3 DOSAGE FORMS AND STRENGTHS
`
`Injection: 100 mg/4 mL (25 mg/mL) of bendamustine hydrochloride as a clear solution in a
`multiple-dose vial.
`
`
`4 CONTRAINDICATIONS
`
`BELRAPZO 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).
`In the event of treatment-related myelosuppression, monitor 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. 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) and (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 BELRAPZO treatment to contact a physician immediately if they have symptoms or
`signs of infection.
`
`Patients treated with bendamustine hydrochloride 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 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
`experience Grade 3 or worse allergic-type reactions should not be rechallenged. Consider
`measures to prevent severe reactions, including antihistamines, antipyretics and corticosteroids in
`
`Reference ID: 4314875
`
`5
`
`

`

`subsequent cycles in patients who have experienced Grade 1 or 2 infusion reactions. Discontinue
`BELRAPZO 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, 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 (5.5)]
`
`
`5.5 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 BELRAPZO.
`
`5.6 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 BELRAPZO therapy.
`
`5.7 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.
`
`5.8 Extravasation Injury
`
`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 BELRAPZO infusion and monitor the intravenous infusion site for redness, swelling,
`pain, infection, and necrosis during and after administration of BELRAPZO.
`
`Reference ID: 4314875

`
`

`

` 5.9 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)]

`
`
`6.1 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
`The data described below reflect exposure to bendamustine hydrochloride in 153 patients with
`CLL studied in an active-controlled, randomized trial. The population was 45-77 years of age,
`63% male, 100% white, and were treatment naïve. 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. 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

`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%).

`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 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 further deterioration does not occur.
`
`Non-Hodgkin Lymphoma
`
`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.

`In both studies, serious adverse reactions, regardless of causality, were reported in 37% of
`patients receiving bendamustine hydrochloride. The most common serious adverse reactions
`occurring in ≥5% of patients were febrile neutropenia and pneumonia. Other important serious
`adverse reactions reported in clinical trials and/or post-marketing experience were acute renal
`failure, cardiac failure, hypersensitivity, skin reactions, pulmonary fibrosis, and myelodysplastic
`syndrome.
`Serious drug-related adverse reactions reported in clinical trials included myelosuppression,
`infection, pneumonia, tumor lysis syndrome and infusion 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.
`
`6.2 Postmarketing Experience
`The following adverse reactions have been identified during post-approval use of bendamustine
`hydrochloride. Because these reactions are reported voluntarily from a population of uncertain
`size, it is not always possible to reliably estimate their frequency or establish a causal
`relationship to drug exposure.
