  • BOXED WARNING (What is this?)

    WARNING: CAPILLARY LEAK SYNDROME and HEMOLYTIC UREMIC SYNDROME

    • Capillary Leak Syndrome (CLS), including life-threatening cases, occurred in patients receiving LUMOXITI. Monitor weight and blood pressure; check labs, including albumin, if CLS is suspected. Delay dosing or discontinue LUMOXITI as recommended [see Dosage and Administration (2.3) and Warnings and Precautions (5.1)].
    • Hemolytic Uremic Syndrome (HUS), including life-threatening cases, occurred in patients receiving LUMOXITI. Monitor hemoglobin, platelet count, serum creatinine, and ensure adequate hydration. Discontinue LUMOXITI in patients with HUS [see Dosage and Administration (2.3) and Warnings and Precautions (5.2)].
  • 1 INDICATIONS AND USAGE

    LUMOXITI is indicated for the treatment of adult patients with relapsed or refractory hairy cell leukemia (HCL) who received at least two prior systemic therapies, including treatment with a purine nucleoside analog (PNA).

    Limitations of Use

    LUMOXITI is not recommended in patients with severe renal impairment (CrCl ≤ 29 mL/min) [see Dosage and Administration (2.3), Warnings and Precautions (5.3), and Use in Specific Populations (8.5)].

  • 2 DOSAGE AND ADMINISTRATION

    2.1 Recommended Dosage

    The recommended dose of LUMOXITI is 0.04 mg/kg administered as a 30-minute intravenous infusion on Days 1, 3, and 5 of each 28-day cycle. Continue LUMOXITI treatment for a maximum of 6 cycles, disease progression, or unacceptable toxicity.

    2.2 Recommended Concomitant Treatment

    Hydration

    Intravenously administer 1 L of isotonic solution (e.g., 5% Dextrose Injection, USP and 0.45% or 0.9% Sodium Chloride Injection, USP) over 2‑4 hours before and after each LUMOXITI infusion. Administer 0.5 L to patients under 50 kg.

    Advise all patients to adequately hydrate with up to 3 L (twelve 8‑oz glasses) of oral fluids (e.g., water, milk, or juice) per 24 hours on Days 1 through 8 of each 28‑day cycle. In patients under 50 kg, up to 2 L (eight 8‑oz glasses) per 24 hours is recommended.

    Monitor fluid balance and serum electrolytes to avoid fluid overload and/or electrolyte abnormalities [see Warnings and Precautions (5.2,5.5)].

    Thromboprophylaxis

    Consider low-dose aspirin on Days 1 through 8 of each 28-day cycle.

    Monitor for signs and symptoms of thrombosis [see Warnings and Precautions (5.2)].

    Premedication

    Premedicate 30‑90 minutes prior to each LUMOXITI infusion with:

    • An antihistamine (e.g., hydroxyzine or diphenhydramine)
    • Acetaminophen antipyretic
    • A histamine‑2 receptor antagonist (e.g., ranitidine, famotidine, or cimetidine)

    If a severe infusion related reaction occurs, interrupt the LUMOXITI infusion and institute appropriate medical management. Administer an oral or intravenous corticosteroid approximately 30 minutes before resuming, and before each LUMOXITI infusion thereafter [see Warnings and Precautions (5.4)].

    Post-infusion Medication

    • Consider oral antihistamines and antipyretics for up to 24 hours following LUMOXITI infusions.
    • An oral corticosteroid (e.g., 4 mg dexamethasone) is recommended to decrease nausea and vomiting.
    • Maintain adequate oral fluid intake.

    2.3 Monitoring to Assess Safety

    Manage adverse reactions by withholding and/or discontinuing LUMOXITI as described below.

    Identify Capillary Leak Syndrome (CLS) and Hemolytic Uremic Syndrome (HUS) based on clinical presentation (see Table 1).

    Table 1: Monitoring for CLS and HUS

    CLS

    HUS

    Monitoring Parameter

    Before every infusion, check:

    • Weight
    • Blood pressure

    Before every infusion, check:

    • Hemoglobin levels
    • Platelet count
    • Serum creatinine

    Assessment

    • If weight has increased by 5.5 pounds (2.5 kg) or 5% or greater from Day 1 of the cycle and the patient is hypotensive, promptly check for peripheral edema, hypoalbuminemia, and respiratory symptoms, including shortness of breath and cough.
    • If CLS is suspected, check for a decrease in oxygen saturation and evidence of pulmonary edema and/or serosal effusions.

    If HUS is suspected, promptly check blood LDH, indirect bilirubin, and blood smear schistocytes for evidence of hemolysis.

    Adverse reactions graded by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03.

    Capillary Leak Syndrome (CLS)

    Patients who experience Grade 2 or higher CLS should receive appropriate supportive measures, including treatment with oral or intravenous corticosteroids, with monitoring of weight, albumin levels, and blood pressure until resolution [see Warnings and Precautions (5.1)].

    Hemolytic Uremic Syndrome (HUS)

    Discontinue LUMOXITI in patients with HUS. Treat with appropriate supportive measures and fluid replacement, with monitoring of blood chemistry, complete blood counts, and renal function until resolution [see Warnings and Precautions (5.2)].

    Increased Creatinine

    For patients with baseline serum creatinine within normal limits, delay dosing for Grade 2 or higher creatinine increases (greater than 1.5‑times baseline or the upper limit of normal). Resume LUMOXITI upon recovery to Grade 1 (1‑ to 1.5‑times baseline, or between the upper limit of normal and 1.5‑times the upper limit of normal).

    For patients with baseline serum creatinine of Grades 1 or 2, delay dosing for creatinine increases to Grade 3 or higher (greater than 3‑times baseline or the upper limit of normal). Resume LUMOXITI upon recovery to baseline grade or lower [see Warnings and Precautions (5.3)].

    2.4 Instructions for Reconstitution, Dilution, and Administration

    LUMOXITI must be reconstituted and diluted by a healthcare provider using aseptic technique. Refer to the Healthcare Provider Instructions for Use for LUMOXITI for full reconstitution, dilution, and administration information.

    Step 1: Calculate Dose

    • Calculate the dose (mg) and the number of LUMOXITI vials (1 mg/vial) to be reconstituted. The final concentration of the reconstituted LUMOXITI solution is 1 mg/mL.
      • o DO NOT round down for partial vials.
    • Individualize dosing based on the patient's actual body weight prior to the first dose of the first treatment cycle.
      • o A change in dose should only be made between cycles when a change in weight of greater than 10% is observed from the weight used to calculate the first dose of the first treatment cycle. No change in dose should be made during a particular cycle.

    Step 2: Reconstitution

    Reconstitute LUMOXITI vials with Sterile Water for Injection, USP only.

    • Reconstitute each LUMOXITI (1 mg/vial) with 1.1 mL Sterile Water for Injection, USP. The resulting 1 mg/mL solution allows a withdrawal volume of 1 mL.
      • o Direct the Sterile Water for Injection, USP along the walls of the vial and not directly at the lyophilized cake or powder.
      • o DO NOT reconstitute LUMOXITI vials with the IV Solution Stabilizer.
    • Gently swirl the vial until completely dissolved. Invert the vial to ensure all cake or powder in the vial is dissolved. Do not shake.
    • Visually inspect that the reconstituted solution is clear to slightly opalescent, colorless to slightly yellow, and free from visible particles. Do not use if solution is cloudy, discolored, or contains any particles.
    • Use reconstituted solution immediately. Do not store reconstituted LUMOXITI vials. See Table 3 for storage times and conditions for the reconstituted solution.

    Step 3: Dilution

    Add the IV Solution Stabilizer to the infusion bag prior to adding LUMOXITI solution to the infusion bag. Vial of IV Solution Stabilizer is packaged separately.

    • Obtain a 50 mL 0.9% Sodium Chloride Injection, USP infusion bag.
    • Add 1 mL IV Solution Stabilizer to the infusion bag containing 50 mL 0.9% Sodium Chloride Injection, USP.
      • o Only one vial of IV Solution Stabilizer should be used per administration of LUMOXITI.
      • o Gently invert the bag to mix the solution. Do not shake.
    • Withdraw the required volume (calculated from Step 1) of LUMOXITI solution from the reconstituted vial(s).
      • o Inject LUMOXITI into the infusion bag containing 50 mL 0.9% Sodium Chloride Injection, USP and 1 mL IV Solution Stabilizer.
      • o Gently invert the bag to mix the solution. Do not shake.
    • Discard any partially used or empty vials of LUMOXITI and IV Solution Stabilizer.
    • See Table 3 for storage times and conditions for the diluted solution.

    Step 4: Administration Instructions

    For intravenous infusion only.

    • Administer the diluted solution intravenously over 30 minutes.
    • Do not mix LUMOXITI, or administer as an infusion with other medicinal products.
    • After the infusion, flush the intravenous administration line with of 0.9% Sodium Chloride Injection, USP at the same rate as the infusion. This ensures that the full LUMOXITI dose is delivered.

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Capillary Leak Syndrome (CLS)

    Capillary leak syndrome (CLS), including life-threatening cases, has been reported among patients treated with LUMOXITI and is characterized by hypoalbuminemia, hypotension, symptoms of fluid overload, and hemoconcentration. In the combined safety database of HCL patients treated with LUMOXITI, CLS occurred in 34% (44/129) of patients, including Grade 2 in 23% (30/129), Grade 3 in 1.6% (2/129), and Grade 4 in 2% (3/129).

    Most cases of CLS occurred in the first 8 days (range: 1 to 19) of a treatment cycle, however, cases have also been reported on other days throughout the cycle. The median time to resolution of CLS was 12 days (range: 1 to 53).

    Monitor patient weight and blood pressure prior to each LUMOXITI infusion and as clinically indicated during treatment. Assess patients for signs and symptoms of CLS, including weight gain (increase in 5.5 pounds (2.5 kg) or ≥ 5% from Day 1 of current cycle), hypotension, peripheral edema, shortness of breath or cough, and pulmonary edema and/or serosal effusions. In addition, the following changes in laboratory parameters may help identify CLS: hypoalbuminemia, elevated hematocrit, leukocytosis, and thrombocytosis [see Dosage and Administration (2.3)].

    CLS may be life-threatening or fatal if treatment is delayed. Counsel patients to seek immediate medical attention should signs or symptoms of CLS occur at any time. Patients who develop CLS should receive appropriate supportive measures, including concomitant oral or intravenous corticosteroids, and hospitalization as clinically indicated. Withhold LUMOXITI for Grade 2 CLS until resolution, and permanently discontinue for Grade ≥ 3 CLS [see Dosage and Administration (2.3)].

    5.2 Hemolytic Uremic Syndrome (HUS)

    Hemolytic Uremic Syndrome (HUS), including life threatening cases, has been reported in patients treated with LUMOXITI and is characterized by the triad of microangiopathic hemolytic anemia, thrombocytopenia, and progressive renal failure. In the combined safety database of HCL patients treated with LUMOXITI, HUS occurred in 7% (9/129) of patients, including Grade 3 in 3% (4/129) and Grade 4 in 0.8% (1/129).

    Most cases of HUS occurred in the first 9 days (range: 1 to 16) of a treatment cycle, however, cases have also been reported on other days throughout the cycle. The median time to resolution of HUS was 11.5 days (range: 2 to 44). All cases resolved, including those who discontinued LUMOXITI.

    Avoid LUMOXITI in patients with prior history of severe thrombotic microangiopathy (TMA) or HUS. Administer prophylactic intravenous fluids before and after LUMOXITI infusions [see Dosage and Administration (2.2)]. In Study 1053, patients with a platelet count ≥ 100,000/mm3 received low-dose aspirin on Days 1 through 8 of each 28-day cycle for prophylaxis of thrombosis.

    Monitor blood chemistry and complete blood counts prior to each dose and on Day 8 of each treatment cycle. Monitoring mid-cycle is also recommended. Consider the diagnosis of HUS in patients who develop hemolytic anemia, worsening or sudden onset of thrombocytopenia, increase in creatinine levels, elevation of bilirubin and/or LDH, and have evidence of hemolysis based on peripheral blood smear schistocytes [see Dosage and Administration (2.3)].

    The events of HUS may be life-threatening if treatment is delayed with increased risk of progressive renal failure requiring dialysis. If HUS is suspected initiate appropriate supportive measures, including fluid repletion, hemodynamic monitoring, and consider hospitalization as clinically indicated. Discontinue LUMOXITI in patients with HUS [see Dosage and Administration (2.3)].

    5.3 Renal Toxicity

    Renal toxicity has been reported in patients treated with LUMOXITI therapy. In the combined safety database of HCL patients treated with LUMOXITI, 26% (34/129) reported adverse events of renal toxicity, including acute kidney injury (2.3%), renal failure (2.3%), renal impairment (1.6%), serum creatinine increased (17%), and proteinuria (8%). Grade 3 acute kidney injury occurred in 1.6% (2/129) of patients. All other events were mild to moderate in severity.

    Based on laboratory findings, during treatment, serum creatinine increased by two or more grades from baseline in 22% (29/129) of patients, including increases of Grade 3 in 1.6% (2/129) of patients. At the end of treatment, serum creatinine levels remained elevated at 1.5- to 3-times the upper limit of normal in 5% of patients. Patients who experience HUS, those ≥ 65 years of age, or those with baseline renal impairment may be at increased risk for worsening of renal function following treatment with LUMOXITI [see Use in Specific Populations (8.5)].

    Monitor renal function prior to each infusion of LUMOXITI, and as clinically indicated throughout treatment. Delay LUMOXITI dosing in patients with Grade ≥ 3 elevations in creatinine, or upon worsening from baseline by ≥ 2 grades [see Dosage and Administration (2.3)].

    5.4 Infusion Related Reactions

    Infusion related reactions occurred in patients treated with LUMOXITI, and were defined as the occurrence of any one of the following events on the day of study drug infusion: chills, cough, dizziness, dyspnea, feeling hot, flushing, headache, hypertension, hypotension, infusion related reaction, myalgia nausea, pyrexia, sinus tachycardia, tachycardia, vomiting, or wheezing. In Study 1053, infusion related reactions occurred in 50% (40/80) of patients. Grade 3 infusion related events as defined, occurred in 11% (9/80) of LUMOXITI-treated patients. The most frequently reported infusion related events were nausea (15%), pyrexia (14%), chills (14%), vomiting (11%), headache (9%), and infusion related reaction (9%).

    Infusion related reactions may occur during any cycle of treatment with LUMOXITI. Prior to each dose of LUMOXITI, premedicate with antihistamines and antipyretics. If a severe infusion related reaction occurs, interrupt the LUMOXITI infusion and institute appropriate medical management. Administer an oral or intravenous corticosteroid approximately 30 minutes before resuming, or before the next LUMOXITI infusion [see Dosage and Administration (2.2)].

    5.5 Electrolyte Abnormalities

    In the combined safety database of HCL patients treated with LUMOXITI, electrolyte abnormalities occurred in 57% (73/129) of patients with the most common electrolyte abnormality being hypocalcemia occurring in 25% of patients. Grade 3 electrolyte abnormalities occurred in 14% (18/129) of patients and Grade 4 electrolyte abnormalities occurred in 0.8% (1/129) of patients. Electrolyte abnormalities co-occurred in the same treatment cycle with CLS, HUS, fluid retention, or renal toxicity in 37% (48/129) of patients.

    Monitor serum electrolytes prior to each dose and on Day 8 of each treatment cycle. Monitoring mid-cycle is also recommended.

  • 6 ADVERSE REACTIONS

    The following adverse reactions are discussed in greater detail in other sections of the labeling.

    6.1 Clinical Trials Experience

    As 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 data described in this section reflect exposure to LUMOXITI in 80 patients with previously treated HCL in Study 1053 [see Clinical Studies (14)]. Patients received LUMOXITI 0.04 mg/kg as an intravenous infusion over 30 minutes on Days 1, 3, and 5 of each 28‑day cycle for a maximum of 6 cycles or until disease progression or unacceptable toxicity.

    The median duration of treatment with LUMOXITI was 5.7 months (range: 0.9 to 6.7), with a median of 6 treatment cycles started in each patient.

    The most common non-laboratory adverse reactions (≥ 20%) of any grade were infusion related reactions, edema, nausea, fatigue, headache, pyrexia, constipation, anemia, and diarrhea. The most common Grade 3 or 4 adverse reactions (reported in at least ≥ 5% of patients) were hypertension, febrile neutropenia, and HUS.

    The most common laboratory abnormalities (≥ 20%) of any grade were creatinine increased, ALT increased, hypoalbuminemia, AST increased, hypocalcemia, hypophosphatemia, hemoglobin decreased, neutrophil count decreased, hyponatremia, blood bilirubin increased, hypokalemia, GGT increased, hypomagnesemia, platelet count decreased, hyperuricemia, and alkaline phosphate increased.

    Adverse reactions resulting in permanent discontinuation of LUMOXITI occurred in 15% (12/80) of patients. The most common adverse reaction leading to LUMOXITI discontinuation was HUS (5%). The most common adverse reaction resulting in dose delays, omissions, or interruptions was pyrexia (3.8%).

    Tables 4 and 5 present the frequency category of adverse reactions and key laboratory abnormalities observed in patients with relapsed or refractory HCL treated with LUMOXITI.

    6.2 Immunogenicity

    As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors, including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to moxetumomab pasudotox-tdfk in the studies described below with the incidence of antibodies in other studies or to other products may be misleading.

    The immunogenicity of LUMOXITI was evaluated using electrochemiluminescent (ECL)-based immunoassay to test for anti-moxetumomab pasudotox-tdfk antibodies (ADA). For patients whose serum tested positive for ADA, a cell-based assay was performed to detect neutralizing antibodies (nAb). In Study 1053, 59% (45/76) of patients tested positive for ADA prior to any treatment with moxetumomab pasudotox-tdfk. Seventy out of 80 subjects tested ADA positive at any point during the study and were subsequently tested for nAb. The results showed that 67 of 70 subjects were nAb-positive. Among these 67 patients who tested nAb-positive, 99% (66/67) had ADA specific to the PE38 binding domain, and 54% (36/67) also had ADA specific to the CD22 binding domain. In 41 out of 73 patients who had baseline and post-baseline ADA results, the median fold increase from baseline (Cycle 1, Day 1) in ADA titer was 3.75- (range: 0 to 240), 54- (range: 0 to 2560), 120- (range: 0 to 1920), and 128- (range: 0 to 2560) fold at Cycles 2, 3, 5, and end-of-treatment, respectively. Patients who tested positive for ADA had decreased systemic moxetumomab pasudotox-tdfk concentrations [see Clinical Pharmacology (12.3)].

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    Based on its mechanism of action and findings in non-pregnant female animals, LUMOXITI is expected to cause maternal and embryo-fetal toxicity when administered to a pregnant woman [see Clinical Pharmacology (12.1) and Nonclinical Toxicology (13.2)]. There are no available data on LUMOXITI use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage. Animal reproduction or developmental toxicity studies have not been conducted with LUMOXITI. 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 2-4% and 15-20%, respectively.

    8.2 Lactation

    Risk Summary

    No data are available regarding the presence of moxetumomab pasudotox-tdfk in human milk, the effects on the breastfed child, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for LUMOXITI and any potential adverse effects on the breastfed child from LUMOXITI or from the underlying maternal condition.

    8.3 Females and Males of Reproductive Potential

    Contraception

    Females

    To avoid potential exposure to the fetus, women of reproductive potential should use effective contraception during treatment with LUMOXITI and for at least 30 days after the last dose is received. Verify the pregnancy status of females of reproductive potential prior to initiating LUMOXITI.

    8.4 Pediatric Use

    Safety and effectiveness have not been established in pediatric patients.

    8.5 Geriatric Use

    In the combined safety database of HCL patients treated with LUMOXITI, 31% (40/129) of patients treated with LUMOXITI were 65 years of age or older and 8% (10/129) were 75 years of age or older. Exploratory analyses across this population suggest a higher incidence of adverse reactions leading to drug discontinuation (23% versus 7%) and renal toxicity (40% versus 20%) for patients 65 years of age or older as compared to those younger than 65 years. Clinical studies of LUMOXITI did not include sufficient numbers of subjects aged 65 and over to determine whether there were differences in efficacy between younger and older patients.

  • 11 DESCRIPTION

    Moxetumomab pasudotox-tdfk is a CD22-directed cytotoxin. Moxetumomab pasudotox-tdfk is composed of a recombinant, murine immunoglobulin variable domain genetically fused to a truncated form of Pseudomonas exotoxin, PE38, that inhibits protein synthesis. Moxetumomab pasudotox-tdfk has an approximate molecular weight of 63 kDa and is produced in E. coli cells by recombinant DNA technology. During the moxetumomab pasudotox-tdfk manufacturing process, fermentation is carried out in nutrient medium containing the antibiotic kanamycin. However, kanamycin is cleared in the manufacturing process and is not detectable in the final product.

    LUMOXITI (moxetumomab pasudotox-tdfk) for injection is supplied as a sterile, preservative-free, white to off-white lyophilized cake or powder in a single-dose vial for reconstitution and dilution prior to intravenous infusion. Each single-dose vial contains 1 mg moxetumomab pasudotox-tdfk, glycine (80 mg), polysorbate 80 (0.2 mg), sodium phosphate monobasic monohydrate (3.4 mg), sucrose (40 mg), and sodium hydroxide to adjust pH to 7.4. After reconstitution with 1.1 mL Sterile Water for Injection, USP, the resulting 1 mg/mL solution allows a withdrawal volume of 1 mL.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Moxetumomab pasudotox-tdfk is a CD22-directed cytotoxin. Moxetumomab pasudotox-tdfk binds CD22 on the cell surface of B-cells and is internalized. Moxetumomab pasudotox-tdfk internalization results in ADP-ribosylation of elongation factor 2, inhibition of protein synthesis, and apoptotic cell death.

    12.2 Pharmacodynamics

    The presence of moxetumomab pasudotox-tdfk may interfere with detection of cellular CD22, therefore, total peripheral blood B-cell counts (including normal B cells and HCL cells) were quantified using a standard assay for CD19+ B cells as a surrogate. In patients with HCL, treatment with LUMOXITI at the approved recommended dosage resulted in a reduction of circulating CD19+ B cells. The circulating CD19+ B cells on Day 8 were reduced by 89% from baseline following the first three infusions of LUMOXITI. B cell reduction was sustained for at least 1-month post-treatment.

    Total counts of CD3+ T cells, CD4+ T cells, CD8+ T cells, and CD16+/CD56 Natural Killer cells and quantitative immunoglobulin (Ig) A, G, and M levels were evaluated throughout the course of treatment. On Day 8, median cell counts were reduced from baseline for the following populations: CD3+ T cells (-21%), CD4+ T cells (-20%), CD8+ T cells (-23%), and CD16+/CD56 Natural Killer cells (-47%). All monitored cell counts returned to, or were elevated above baseline levels on Day 29 and thereafter. At baseline, the median IgA, IgG, and IgM levels were 107 mg/dL (11-260), 834 mg/dL (387-3003), and 42 mg/dL (6-380), respectively, and remained generally unchanged at the end of treatment.

    12.3 Pharmacokinetics

    The pharmacokinetics (PK) of moxetumomab pasudotox-tdfk was studied in patients with HCL at doses ranging from 0.005 to 0.05 mg/kg (about 0.1 to 1.3 times the approved recommended dosage) administered intravenously over 30 minutes on Days 1, 3, and 5 of a 28-day cycle. Moxetumomab pasudotox-tdfk concentrations increased dose-proportionally over the studied dose range. The mean steady state moxetumomab pasudotox-tdfk exposures at the approved recommended dosages were 379 ng/mL (range: 20 to 862; SD: 262) for Cmax and 626 ng·hour/mL (range: 5 to 1960; SD: 610) for AUC0-last. No systemic accumulation of moxetumomab pasudotox-tdfk was observed. Baseline CD19+ B cells were evaluated for association with the PK exposure and higher PK exposures were significantly associated with low baseline CD19+ counts (p < 0.001).

    Distribution

    The population PK model estimated mean volume of distribution of moxetumomab pasudotox-tdfk was 6.5 L (SD 2.4).

    Elimination

    The mean elimination half-life of moxetumomab pasudotox-tdfk was 1.4 hours (range: 0.8 to 1.8; SD: 0.35). The population PK model estimated mean systemic clearance of moxetumomab pasudotox-tdfk after the first dose of the first cycle was 25 L/hour (SD: 29.0) and after subsequent dosing was 4 L/hour (SD: 4.4).

    Metabolism

    The metabolic pathway of moxetumomab pasudotox-tdfk in humans is unknown, however, other protein therapeutics generally undergo proteolytic degradation into small peptides and amino acids via catabolic pathways.

    Specific Populations

    No clinically significant differences in the pharmacokinetics of moxetumomab pasudotox-tdfk were observed for age (36 to 84 years), sex, race (White and non-White), body weight (42 to 152 kg), mild hepatic impairment (total bilirubin ≤ upper limit of normal [ULN] and AST > ULN, or total bilirubin > 1 to 1.5 times ULN and any AST), mild renal impairment (CLcr 60-89 mL/min; n=40), or moderate renal impairment (CLcr 30-59 mL/min; n=4) based on population PK analysis.

    The pharmacokinetics of moxetumomab pasudotox-tdfk in patients with moderate to severe hepatic impairment (total bilirubin > 1.5 ULN) or severe renal impairment (CrCl ≤ 29 mL/min) is unknown.

    Anti-Product Antibody Formation Affecting PK

    In patients who were ADA-positive with high titers, the presence of ADA post-baseline was associated with statistically significant (p < 0.05) lower PK exposure (Cmax) at later cycles (Cycle 3 and beyond).

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    No studies have been conducted to assess the carcinogenic or genotoxic potential of moxetumomab pasudotox-tdfk. Animal fertility studies have not been conducted with moxetumomab pasudotox-tdfk.

    13.2 Animal Toxicology and/or Pharmacology

    At a human equivalent dose > 3 times the recommended dose, degeneration of heart tissue was observed in cynomolgus monkeys. At a human equivalent dose > 10 times the recommended dose, gliosis in the brain, axonal degeneration in the spinal cord, and body tremors were observed in cynomolgus monkeys.

  • 14 CLINICAL STUDIES

    The efficacy of LUMOXITI was based upon Study 1053 titled “A Pivotal Multicenter Trial of Moxetumomab Pasudotox in Relapsed/Refractory Hairy Cell Leukemia” (NCT01829711). Study 1053 was conducted in patients with histologically confirmed HCL or HCL variant with a need for therapy based on presence of cytopenias or splenomegaly and who had received prior treatment with at least 2 systemic therapies, including 1 purine nucleoside analog (PNA). Eligible patients had serum creatinine ≤ 1.5 mg/dL or creatinine clearance ≥ 60 mL/min as estimated by the Cockcroft Gault equation.

    A total of 80 patients were enrolled; 77 with classic HCL and 3 with HCL variant. The median age was 60 years (range: 34 to 84) years, 79% were male, and 94% were Caucasian. At baseline, 98% of patients had an ECOG performance status of 0 or 1. The median number of prior treatments was 3 (range: 2 to 11); all patients received prior PNA therapy, including 29% in combination with rituximab. The most common other prior treatment regimens were rituximab monotherapy (51%), interferon-alpha (25%), and a BRAF inhibitor (18%). At baseline, 33% (26/80) of patients had low hemoglobin (< 10 g/dL), 68% (54/80) of patients had neutropenia (< 1000/mm3), and 84% (67/80) patients had baseline platelet counts < 100,000/mm3. About 35% of patients had enlarged spleens (≥ 14 cm, assessed by BICR) at baseline.

    Patients received LUMOXITI 0.04 mg/kg as an intravenous infusion over 30 minutes on Days 1, 3, and 5 of each 28‑day cycle for a maximum of 6 cycles or until documentation of complete response (CR), disease progression, or unacceptable toxicity. The median duration of follow-up was 16.7 months (range: 2 to 49). An independent review committee (IRC) performed efficacy evaluations using blood, bone marrow, and imaging criteria adapted from previous HCL studies and consensus guidelines.

    Efficacy of LUMOXITI in HCL was evaluated by the IRC-assessed rate of durable CR, as confirmed by maintenance of hematologic remission (hemoglobin ≥ 11 g/dL, neutrophils ≥ 1500/mm3, and platelets ≥ 100,000/mm3 without transfusions or growth factor for at least 4 weeks) more than 180 days after IRC-assessed CR. The IRC-assessed durable CR rate was 30% (24/80 patients; 95% CI: 20, 41).

    Additional efficacy outcome measures included overall response rate (ORR), CR, and duration of response (see Table 6).

    for injection

    What is the most important information I should know about LUMOXITI?

    LUMOXITI can cause serious side effects, including:

    • Capillary Leak Syndrome (CLS). LUMOXITI can cause fluid to leak from small blood vessels into your body’s tissues. This condition is called “Capillary Leak Syndrome” (CLS). CLS can quickly cause you to have symptoms that may become life-threatening if not treated right away. Get emergency medical help right away if you develop any of the following symptoms of CLS:
    • o swelling of your face, arms, or legs
    • o fast weight gain (increase in 5.5 pounds from Day 1 of your current cycle)
    • o weakness or dizziness
    • o shortness of breath or trouble breathing
    • o cough
    • o low blood pressure
    •   Your healthcare provider will check your weight and blood pressure before you receive each dose of LUMOXITI and as needed during treatment.
    • Hemolytic Uremic Syndrome (HUS). Hemolytic uremic syndrome is a condition that affects your blood cells and kidneys and may be life-threatening if not treated right away. Get emergency medical help right away if you develop any of the following symptoms of HUS:
    • o decrease in the amount of urine or dark urine (tea-colored)
    • o unusual bleeding or bruising of your skin
    • o stomach pain
    • o vomiting
    • o fever
    • o feeling tired
    • o changes in mood or behavior
    • o confusion
    • o seizures
    • o shortness of breath
    • o fast heartbeat
    •   Your healthcare provider will do blood tests to check your blood cells and kidneys before you receive each dose of LUMOXITI and during treatment as recommended by your healthcare provider.

    If you develop any of these symptoms of CLS or HUS, your healthcare provider may monitor you in the hospital.

    Getting medical treatment right away may help keep these problems from becoming more serious.

    Your healthcare provider will check you for these problems during your treatment with LUMOXITI. Your healthcare provider may delay or completely stop treatment with LUMOXITI if you have severe side effects.

    See “What are the possible side effects of LUMOXITI?” below for other side effects of LUMOXITI.

    Step_3_Lumoxiti_moxetumomab_vial_blue_capStep 3: Reconstitution 1.1 mL Sterile Water for Injection
    • Direct the Sterile Water for Injection, USP slowly along the walls of the LUMOXITI vial and not directly at the lyophilized cake or powder (see figure below).
    Step3: Lumoxiti vial bottle and syringe
    • Do not reconstitute LUMOXITI vials with the IV Solution Stabilizer.
    • Gently swirl the vial until completely dissolved. Invert the vial to ensure all cake or powder in the vial is dissolved. Do not shake.

    Visually inspect that the reconstituted solution is clear to slightly opalescent, colorless to slightly yellow, and free from visible particles.

    • Do not use if solution is cloudy, discolored, or contains any particles.

    The resulting 1 mg/mL solution allows a withdrawal volume of 1 mL.

    Use reconstituted solution immediately. Do not store reconstituted LUMOXITI vials. See Table 1 for storage times and conditions for the reconstituted solution.

    Step 4: Preparation of Infusion Bag with IV Solution Stabilizer

    Step 4: IV Solution Stabilizer for LUMOXITI VialStep 4: Sodium Chloride infusion bag

    Obtain a 50 mL 0.9% Sodium Chloride Injection, USP infusion bag.

    Only one vial of IV Solution Stabilizer is needed per administration of LUMOXITI, regardless of the number of vials of LUMOXITI used to prepare the infusion.

    • Add 1 mL IV Solution Stabilizer to the infusion bag containing 50 mL 0.9% Sodium Chloride Injection, USP.
    • Gently invert the bag to mix the solution. Do not shake.

    Step 5: Dilution

    Slowly withdraw the required volume of reconstituted LUMOXITI solution needed from each vial, per the calculated dose based on the patient’s actual body weight (kg).

    • Inject LUMOXITI into the infusion bag containing 50 mL 0.9% Sodium Chloride Injection, USP and 1 mL IV Solution Stabilizer.
    • Gently invert the bag to mix the solution. Do not shake.
    • Discard any partially used or empty vials of LUMOXITI and IV Solution Stabilizer.
    • See Table 1 for storage times and conditions for the diluted solution.

    Step 6: Intravenous Hydration and Pre-infusion Medications

    Administer intravenous hydration and premedication to the patient.

    • Intravenously administer 1 L of isotonic solution (e.g. 5% Dextrose Injection, USP and 0.45% or 0.9% Sodium Chloride Injection, USP) over 2 to 4 hours before each LUMOXITI infusion. Administer 0.5 L to patients under 50 kg.
    • Premedicate 30 to 90 minutes prior to each LUMOXITI infusion with an antihistamine (e.g. hydroxyzine or diphenhydramine), acetaminophen, and a histamine-2 receptor antagonist (e.g. ranitidine, famotidine, or cimetidine).

    Step 7: Administration

    Infuse the diluted LUMOXITI solution intravenously over 30 minutes.

    • Do not mix LUMOXITI, or administer as an infusion with other medicinal products.
    • After the infusion, flush the intravenous administration line with of 0.9% Sodium Chloride Injection, USP at the same rate as the infusion. This ensures that the full LUMOXITI dose is delivered.

    Step 8: Post-infusion Medications

    Administer post-infusion medications.

    • Intravenously administer 1 L of isotonic solution (e.g. 5% Dextrose Injection, USP and 0.45% or 0.9% Sodium Chloride Injection, USP) over 2 to 4 hours after each LUMOXITI infusion. Administer 0.5 L to patients under 50 kg.
    • Consider oral antihistamines and acetaminophen for up to 24 hours following LUMOXITI infusions.
    • Consider oral corticosteroid (e.g. 4 mg dexamethasone) to manage nausea and vomiting.

    Maintain adequate oral fluid intake.

    • Advise all patients to adequately hydrate with up to 3 L (twelve 8-oz glasses) of oral fluids (e.g. water, milk, or juice) per 24 hours on Days 1 through 8 of each 28-day treatment cycle. In patients under 50 kg, up to 2 L (eight 8-oz glasses) per 24-hour period is recommended.

    Consider low-dose aspirin on Days 1 through 8 of each 28-day treatment cycle.
