`
`BELRAPZO is in a multiple-dose vial. 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 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 from the 25 mg/mL solution as
`per Table A below and immediately transfer to a 500 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.
`-
`The resulting final concentration of bendamustine HCl in the infusion bag should be within 0.05
`to 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.

`
`2.4 Admixture Stability
`BELRAPZO 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°C
`to 8°C or 36°F to 46°F) or for 3 hours when stored at room temperature (15°C to 30°C or 59°F 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°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)
`BELRAPZO is supplied as a multiple-dose vial. Although it does not contain any antimicrobial
`preservative, BELRAPZO 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 original carton at 2°C to 8°C (36°F to 46°F), and
`then discard after 28 days.
`
`Reference ID: 4871627

`
`
`
`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
`
`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 (5.4)]
`
`5 WARNINGS AND PRECAUTIONS
`
`5.1 Myelosuppression
`
`Bendamustine hydrochloride caused severe myelosuppression (Grade 3-4) in 98% of patients in
`the two NHL studies [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).
`BELRAPZO 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 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 [see Adverse Reactions (6.1)]. 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 BELRAPZO 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 BELRAPZO treatment and perform appropriate diagnostic evaluations.
`Consider discontinuation or reduction of any concomitant chemotherapy or immunosuppressive
`therapy in patients who develop PML.
`
`Reference ID: 4871627
`
`5
`
`
`
`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 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 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.
`
`5.5 Tumor Lysis Syndrome
`Tumor lysis syndrome associated with bendamustine hydrochloride has occurred in patients in
`clinical trials and in post-marketing 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 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 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.
`
`5.7 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 BELRAPZO 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
`
`Reference ID: 4871627
`
`6
`
`
`
`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 BELRAPZO.
`
`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 BELRAPZO infusion and monitor the intravenous
`infusion site for redness, swelling, pain, infection, and necrosis during and after administration of
`BELRAPZO.
`
`5.10 Embryo-Fetal Toxicity
`Based on findings from animal reproduction studies and the drug’s mechanism of action,
`BELRAPZO 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 BELRAPZO and for 6 months after the last dose. Advise males with
`female partners of reproductive potential to use effective contraception during treatment with
`BELRAPZO 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.
`
`
`
`
`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, 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 further deterioration does not occur.
`
` 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.
