  • 4 CONTRAINDICATIONS

    None.

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Neutropenia

    In Study 1, severe neutropenia (ANC < 500/mm3) lasting more than one week occurred in 12% (62/503) of patients with metastatic breast cancer, leading to discontinuation in <1% of patients.  Febrile neutropenia (fever ≥38.5°C with Grade 3 or 4 neutropenia) occurred in 5% (23/503) of patients; two patients (0.4%) died from complications of febrile neutropenia [see Adverse Reactions (6.1)].

    In Study 1, patients with alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 3 × ULN (upper limit of normal) experienced a higher incidence of Grade 4 neutropenia and febrile neutropenia than patients with normal aminotransferase levels. Patients with bilirubin > 1.5 × ULN also had a higher incidence of Grade 4 neutropenia and febrile neutropenia.

    In Study 2, severe neutropenia (ANC < 500/mm3) lasting more than one week occurred in 12% (26/222) of patients with liposarcoma or leiomyosarcoma. Febrile neutropenia occurred in 0.9% of patients treated with eribulin mesylate injection and fatal neutropenic sepsis in 0.9% [see Adverse Reactions (6.1)].

    Monitor complete blood counts prior to each dose; increase the frequency of monitoring in patients who develop Grade 3 or 4 cytopenias. Delay administration of eribulin mesylate injection and reduce subsequent doses in patients who experience febrile neutropenia or Grade 4 neutropenia lasting longer than 7 days [see Dosage and Administration (2.2)]. Clinical studies of eribulin mesylate injection did not include patients with baseline neutrophil counts below 1,500/mm3.

    5.2 Peripheral Neuropathy

    In Study 1, Grade 3 peripheral neuropathy occurred in 8% (40/503) of patients, and Grade 4 in 0.4% (2/503) of patients with metastatic breast cancer (MBC). Peripheral neuropathy was the most common toxicity leading to discontinuation of eribulin mesylate injection (5% of patients; 24/503) in Study 1.  Neuropathy lasting more than one year occurred in 5% (26/503) of patients. Twenty-two percent (109/503) of patients developed a new or worsening neuropathy that had not recovered within a median follow-up duration of 269 days (range 25-662 days).

    In Study 2, Grade 3 peripheral neuropathy occurred in 3.1% (7/223) of eribulin mesylate injection-treated patients. Peripheral neuropathy led to discontinuation of eribulin mesylate injection in 0.9% of patients. The median time to first occurrence of peripheral neuropathy of any severity was 5 months (range: 3.5 months to 9 months).  Neuropathy lasting more than 60 days occurred in 58% (38/65) of patients.  Sixty three percent (41/65) had not recovered within a median follow-up duration of 6.4 months (range: 27 days to 29 months).

    Monitor patients closely for signs of peripheral motor and sensory neuropathy. Withhold eribulin mesylate injection in patients who experience Grade 3 or 4 peripheral neuropathy, until resolution to Grade 2 or less [see Dosage and Administration (2.2)].

    5.3 Embryo-Fetal Toxicity

    Based on findings from an animal reproduction study and its mechanism of action, eribulin mesylate injection can cause fetal harm when administered to a pregnant woman.  There are no adequate and well-controlled studies of eribulin mesylate injection in pregnant women. In animal reproduction studies, eribulin mesylate caused embryo-fetal toxicity when administered to pregnant rats during organogenesis at doses below the recommended human dose. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with eribulin mesylate injection and for at least 2 weeks following the final dose.  Advise males with female partners of reproductive potential to use effective contraception during treatment with eribulin mesylate injection and for 3.5 months following the final dose [see Use in Specific Populations (8.1)].

    5.4 QT Prolongation

    In an uncontrolled open-label ECG study in 26 patients, QT prolongation was observed on Day 8, independent of eribulin concentration, with no QT prolongation observed on Day 1. ECG monitoring is recommended if therapy is initiated in patients with congestive heart failure, bradyarrhythmias, drugs known to prolong the QT interval, including Class Ia and III antiarrhythmics, and electrolyte abnormalities. Correct hypokalemia or hypomagnesemia prior to initiating eribulin mesylate injection and monitor these electrolytes periodically during therapy. Avoid eribulin mesylate injection in patients with congenital long QT syndrome.

  • 6 ADVERSE REACTIONS

    6.1 Clinical Trials Experience

    Because clinical trials are conducted under widely varying conditions, the adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in other clinical trials and may not reflect the rates observed in clinical practice.

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

    In clinical trials, eribulin mesylate injection has been administered to 1963 patients including 467 patients exposed to eribulin mesylate injection for 6 months or longer. The majority of the 1963 patients were women (92%) with a median age of 55 years (range: 17 to 85 years). The racial and ethnic distribution was White (72%), Black (4%), Asian (9%), and other (3%).

    Metastatic Breast Cancer

    The most common adverse reactions (≥25%) reported in patients receiving eribulin mesylate injection were neutropenia, anemia, asthenia/fatigue, alopecia, peripheral neuropathy, nausea, and constipation. The most common serious adverse reactions reported in patients receiving eribulin mesylate injection were febrile neutropenia (4%) and neutropenia (2%). The most common adverse reaction resulting in discontinuation of eribulin mesylate injection was peripheral neuropathy (5%).

    The adverse reactions described in Table 2 were identified in 750 patients treated in Study 1 [see Clinical Studies (14.1)]. In Study 1, patients were randomized (2:1) to receive either eribulin mesylate injection (1.4 mg/m2on Days 1 and 8 of a 21-day cycle) or single agent treatment chosen by their physician (control group). A total of 503 patients received eribulin mesylate injection and 247 patients in the control group received therapy consisting of chemotherapy [total 97% (anthracyclines 10%, capecitabine 18%, gemcitabine 19%, taxanes 15%, vinorelbine 25%, other chemotherapies 10%)] or hormonal therapy (3%). The median duration of exposure was 118 days for patients receiving eribulin mesylate injection and 63 days for patients receiving control therapy. Table 2 reports the most common adverse reactions occurring in at least 10% of patients in either group.

    Cytopenias: Grade 3 neutropenia occurred in 28% (143/503) of patients who received eribulin mesylate injection in Study 1, and 29% (144/503) of patients experienced Grade 4 neutropenia. Febrile neutropenia occurred in 5% (23/503) of patients; two patients (0.4%) died from complications of febrile neutropenia. Dose reduction due to neutropenia was required in 12% (62/503) of patients and discontinuation was required in <1% of patients.  The mean time to nadir was 13 days and the mean time to recovery from severe neutropenia (<500/mm3) was 8 days.  Grade 3 or greater thrombocytopenia occurred in 1% (7/503) of patients.  G-CSF (granulocyte colony-stimulating factor) or GM-CSF (granulocyte–macrophage colony-stimulating factor) was used in 19% of patients who received eribulin mesylate injection.  

    Peripheral Neuropathy:  In Study 1, 17% of enrolled patients had Grade 1 peripheral neuropathy and 3% of patients had Grade 2 peripheral neuropathy at baseline. Dose reduction due to peripheral neuropathy was required by 3% (14/503) of patients who received eribulin mesylate injection. Four percent (20/503) of patients experienced peripheral motor neuropathy of any grade and 2% (8/503) of patients developed Grade 3 peripheral motor neuropathy.

    Liver Function Test Abnormalities:  Among patients with Grade 0 or 1 ALT levels at baseline, 18% of eribulin mesylate injection-treated patients experienced Grade 2 or greater ALT elevation. One eribulin mesylate injection-treated patient without documented liver metastases had concomitant Grade 2 elevations in bilirubin and ALT; these abnormalities resolved and did not recur with re-exposure to eribulin mesylate injection.

    Less Common Adverse Reactions: The following additional adverse reactions were reported in ≥5% to <10% of the eribulin mesylate injection-treated group:

    • Eye Disorders:  increased lacrimation
    • Gastrointestinal Disorders:  dyspepsia, abdominal pain, stomatitis, dry mouth
    • General Disorders and Administration Site Conditions: peripheral edema
    • Infections and Infestations:  upper respiratory tract infection
    • Metabolism and Nutrition Disorders:  hypokalemia
    • Musculoskeletal and Connective Tissue Disorders: muscle spasms, muscular weakness
    • Nervous System Disorders:  dysgeusia, dizziness
    • Psychiatric Disorders:  insomnia, depression
    • Skin and Subcutaneous Tissue Disorders:  rash

    Liposarcoma

    The safety of eribulin mesylate injection was evaluated in Study 2, an open-label, randomized, multicenter, active-controlled trial, in which patients were randomized (1:1) to receive either eribulin mesylate injection 1.4 mg/m2 on Days 1 and 8 of a 21-day cycle or dacarbazine at doses of 850 mg/m2 (20%), 1000 mg/m2 (64%), or 1200 mg/m2 (16%) every 3 weeks.  A total of  223 patients received eribulin mesylate injection and 221 patients received dacarbazine. Patients were required to have received at least two prior systemic chemotherapy regimens.  The trial excluded patients with pre-existing ≥ Grade 3 peripheral neuropathy, known central nervous system metastasis, elevated serum bilirubin or significant chronic liver disease, history of myocardial infarction within 6 months, history of New York Heart Association Class II or IV heart failure, or cardiac arrhythmia requiring treatment. The median age of the safety population in Study 2 was 56 years (range: 24 to 83 years); 67% female; 73% White, 3% Black or African American, 8% Asian/Pacific Islander, and 15% unknown; 99% received prior anthracycline-containing regimen; and 99% received ≥ 2 prior regimens. The median duration of exposure was 2.3 months (range: 21 days to 26 months) for patients receiving eribulin mesylate injection [see Clinical Studies (14.2)].

    The most common adverse reactions (≥25%) reported in patients receiving eribulin mesylate injection were fatigue, nausea, alopecia, constipation, peripheral neuropathy, abdominal pain, and pyrexia.  The most common (≥5%) Grade 3-4 laboratory abnormalities reported in patients receiving eribulin mesylate injection were neutropenia, hypokalemia, and hypocalcemia. The most common serious adverse reactions reported in patients receiving eribulin mesylate injection were neutropenia (4.9%) and pyrexia (4.5%). Permanent discontinuation of eribulin mesylate injection for adverse reactions occurred in 8% of patients. The most common adverse reactions resulting in discontinuation of eribulin mesylate injection were fatigue and thrombocytopenia (0.9% each).  Twenty-six percent of patients required at least one dose reduction. The most frequent adverse reactions that led to dose reduction were neutropenia (18%) and peripheral neuropathy (4.0%).

  • 7 DRUG INTERACTIONS

    7.1 Effects of Other Drugs on Eribulin Mesylate Injection

    No drug-drug interactions are expected with CYP3A4 inhibitors, CYP3A4 inducers or P-glycoprotein (P-gp) inhibitors. Clinically meaningful differences in exposure (AUC) were not observed in patients with advanced solid tumors when eribulin mesylate injection was administered with or without ketoconazole (a strong inhibitor of CYP3A4 and a P-gp inhibitor) and when eribulin mesylate injection was administered with or without rifampin (a CYP3A4 inducer) [see Clinical Pharmacology (12.3)].

    7.2 Effects of Eribulin Mesylate Injection on Other Drugs

    Eribulin does not inhibit CYP1A2, CYP2C9, CYP2C19, CYP2D6, CYP2E1 or CYP3A4 enzymes or induce CYP1A2, CYP2C9, CYP2C19 or CYP3A4 enzymes at relevant clinical concentrations. Eribulin is not expected to alter the plasma concentrations of drugs that are substrates of these enzymes [see Clinical Pharmacology (12.3)].

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    Based on findings from an animal reproduction study and its mechanism of action, eribulin mesylate injection can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no available data on the use of eribulin mesylate injection during pregnancy. In an animal reproduction study, eribulin mesylate caused embryo-fetal toxicity when administered to pregnant rats during organogenesis at doses below the recommended human dose [see Data].  Advise pregnant women of the potential risk to a fetus.

    The estimated background risks of major birth defects and miscarriage for the indicated populations are unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically-recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

    Data

    Animal Data

    In an embryo-fetal developmental toxicity study, pregnant rats received intravenous infusion of eribulin mesylate during organogenesis (Gestation Days 8, 10, and 12) at doses approximately 0.04, 0.13, 0.43 and 0.64 times the recommended human dose, based on body surface area. Increased abortion and severe fetal external or soft tissue malformations, including the absence of a lower jaw and tongue, or stomach and spleen, were observed at doses 0.64 times the recommended human dose of 1.4 mg/m2 based on body surface area. Increased embryo-fetal death/resorption, reduced fetal weights, and minor skeletal anomalies consistent with developmental delay were also reported at doses at or above a maternally toxic dose of approximately 0.43 times the recommended human dose.

    8.2 Lactation

    Risk Summary

    There is no information regarding the presence of eribulin mesylate or its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production. No lactation studies in animals were conducted.  Because of the potential for serious adverse reactions in breastfed infants from eribulin mesylate, advise women not to breastfeed during treatment with eribulin mesylate injection and for 2 weeks after the final dose.

    8.3 Females and Males of Reproductive Potential

    Contraception

    Females

    Based on findings from an animal reproduction study and its mechanism of action, eribulin mesylate injection can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)].  Advise females of reproductive potential to use effective contraception during treatment with eribulin mesylate injection and for at least 2 weeks following the final dose.

    Males

    Based on its mechanism of action, advise males with female partners of reproductive potential to use effective contraception during treatment with eribulin mesylate injection and for 3.5 months following the final dose.

    Infertility

    Males

    Based on animal data, eribulin mesylate injection may result in damage to male reproductive tissues leading to impaired fertility of unknown duration [see Nonclinical Toxicology (13.1)].

    8.4 Pediatric Use

    The safety and effectiveness of eribulin mesylate injection in pediatric patients have not been established.

    Pediatric use information is approved for Eisai Inc.’s HALAVEN® (eribulin mesylate) injection. However, due to Eisai Inc.’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.

    8.5 Geriatric Use

    Study 1 did not include sufficient numbers of subjects with metastatic breast cancer aged 65 years and older to determine whether they respond differently from younger subjects. Of the 827 subjects who received the recommended dose and schedule of eribulin mesylate injection in clinical studies with advanced breast cancer, 15% (121/827) were 65 and older, and 2% (17/827) patients were 75 and older. No overall differences in safety were observed between these subjects and younger subjects.

    Clinical studies of eribulin mesylate injection did not include a sufficient number of subjects in Study 2 aged 65 years and older to determine whether they respond differently from younger subjects.

    8.6 Hepatic Impairment

    Administration of eribulin mesylate injection at a dose of 1.1 mg/m2 to patients with mild hepatic impairment and 0.7 mg/m2 to patients with moderate hepatic impairment resulted in similar exposure to eribulin as a dose of 1.4 mg/m2 to patients with normal hepatic function. Therefore, a lower starting dose of 1.1 mg/m2 is recommended for patients with mild hepatic impairment (Child-Pugh A) and of 0.7 mg/m2 is recommended for patients with moderate hepatic impairment (Child-Pugh B). Eribulin mesylate injection was not studied in patients with severe hepatic impairment (Child-Pugh C) [see Dosage and Administration (2.1), Clinical Pharmacology (12.3)].

    8.7 Renal Impairment

    For patients with moderate or severe renal impairment (CLcr 15-49 mL/min), reduce the starting dose to 1.1 mg/m2[see Dosage and Administration (2.1), Clinical Pharmacology (12.3)].

  • 10 OVERDOSAGE

    Overdosage of eribulin mesylate injection has been reported at approximately 4 times the recommended dose, which resulted in Grade 3 neutropenia lasting seven days and a Grade 3 hypersensitivity reaction lasting one day.

    There is no known antidote eribulin mesylate injection overdose.

  • 11 DESCRIPTION

    Eribulin mesylate injection contains eribulin mesylate, a microtubule dynamics inhibitor. Eribulin mesylate is a synthetic analogue of halichondrin B, a product isolated from the marine sponge Halichondria okadai. The chemical name for eribulin mesylate is 11,15:18,21:24,28-Triepoxy-7,9-ethano-12,15-methano-9H,15H-furo[3,2-i]furo[2',3':5,6]pyrano[4,3-b][1,4]dioxacyclopentacosin-5(4H)-one, 2-[(2S)-3-amino-2-hydroxypropyl]hexacosahydro-3-methoxy-26-methyl-20,27-bis(methylene)-, (2R,3R,3aS,7R,8aS,9S,10aR,11S,12R,13aR,13bS,15S,18S,21S,24S,26R,28R,29aS)-, methanesulfonate (salt). It has a molecular weight of 826.0 (729.9 for free base). The empirical formula is C40H59NO11CH4O3S. Eribulin mesylate has the following structural formula:

    structural formula

    Eribulin mesylate injection is a clear, colorless, sterile solution for intravenous administration. Each single-dose vial contains 1 mg of eribulin mesylate in 2 mL of solution. Each mL of solution contains 0.5 mg of eribulin mesylate (equivalent to 0.44 mg eribulin) in dehydrated alcohol (5% v/v) and water for injection (95% v/v). Sodium hydroxide or hydrochloric acid may be used for pH adjustment.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Eribulin inhibits the growth phase of microtubules without affecting the shortening phase and sequesters tubulin into nonproductive aggregates. Eribulin exerts its effects via a tubulin-based antimitotic mechanism leading to G2/M cell-cycle block, disruption of mitotic spindles, and, ultimately, apoptotic cell death after prolonged mitotic blockage.

    In addition, eribulin treatment of human breast cancer cells caused changes in morphology and gene expression as well as decreased migration and invasiveness in vitro. In mouse xenograft models of human breast cancer, eribulin treatment was associated with increased vascular perfusion and permeability in the tumor cores, resulting in reduced tumor hypoxia, and changes in the expression of genes in tumor specimens associated with a change in phenotype.

    12.2 Pharmacodynamics

    Cardiac Electrophysiology

    The effect of eribulin mesylate injection on the QTc interval was assessed in an open-label, uncontrolled, multicenter, single-arm dedicated QT trial. A total of 26 patients with solid tumors received 1.4 mg/m2 of eribulin mesylate injection on Days 1 and 8 of a 21-day cycle. A delayed QTc prolongation was observed on Day 8, with no prolongation observed on Day 1.  The maximum mean QTcF change from baseline (95% upper confidence interval) was 11.4 (19.5) ms.

    12.3 Pharmacokinetics

    The pharmacokinetics (PK) of eribulin is linear with a mean elimination half-life of approximately 40 hours, a mean volume of distribution of 43 L/m2 to 114 L/m2 and mean clearance of 1.16 L/hr/m2 to 2.42 L/hr/m2 over the dose range of 0.25 mg/m2 to 4.0 mg/m2.  The human plasma protein binding of eribulin at concentrations of 100 ng/mL to 1,000 ng/mL ranges from 49% to 65%. Eribulin exposure after multiple dosing is comparable to that following a single dose. No accumulation of eribulin is observed with weekly administration.

    Elimination

    Metabolism

    Unchanged eribulin was the major circulating species in plasma following administration of 14C-eribulin to patients. Metabolite concentrations represented <0.6% of parent compound, confirming that there are no major human metabolites of eribulin.  Cytochrome P450 3A4 (CYP3A4) negligibly metabolizes eribulin in vitro.

    Excretion

    Eribulin is eliminated primarily in feces unchanged. After administration of 14C-eribulin to patients, approximately 82% of the dose was eliminated in feces and 9% in urine.  Unchanged eribulin accounted for approximately 88% and 91% of total eribulin in feces and urine, respectively. 

    Specific Populations

    Age, Sex, and Race/Ethnicity:  Based on a population pharmacokinetic analysis, no clinically meaningful differences in the pharmacokinetics of eribulin were observed based on age, sex, or race.

    Hepatic Impairment

    In a study evaluating the effect of hepatic impairment on the PK of eribulin, eribulin exposures increased by 1.8-fold in patients with mild hepatic impairment (Child-Pugh A; n=7) and by 2.5-fold in patients with moderate (Child-Pugh B; n=5) hepatic impairment as compared to patients with normal hepatic function (n=6).  Administration of eribulin mesylate injection at a dose of 1.1 mg/m2 to patients with mild hepatic impairment and 0.7 mg/m2 to patients with moderate hepatic impairment resulted in similar exposure to eribulin at a dose of 1.4 mg/m2 to patients with normal hepatic function [see Dosage and Administration (2.1), Use in Specific Populations (8.6)].

    Renal Impairment

    In a study evaluating the effect of renal impairment on the PK of eribulin, patients with moderate (CLcr 30-49 mL/min; n=7) and severe renal impairment (CLcr 15-29 mL/min; n=6) had 1.5-fold higher eribulin dose-normalized exposures compared to that in patients with normal renal function (CLcr ≥ 80 mL/min; n=6).  There were no clinically meaningful changes in patients with mild renal impairment (CLcr 50-79 mL/min; n=27) [see Dosage and Administration (2.1), Use in Specific Populations (8.7)].

    Drug Interaction Studies

    Effect of Strong Inhibitors or Inducers of CYP3A4 on Eribulin: The effect of a strong CYP3A4 inhibitor and a P-gp inhibitor, ketoconazole, on the PK of eribulin was studied in a crossover trial of 12 patients with advanced solid tumors. No clinically relevant PK interaction was observed when eribulin mesylate injection was administered with or without ketoconazole (the geometric mean ratio of the AUC: 0.97; 90% CI: 0.83, 1.12).

    The effect of a CYP3A4 inducer, rifampin, on the PK of eribulin was studied in a crossover trial of 14 patients with advanced solid tumors. No clinically relevant PK interaction was observed when eribulin mesylate injection was administered with or without rifampin (the geometric mean ratio of the AUC: 1.10; 90 CI%: 0.91, 1.34).

    Effect of Eribulin on CYP Substrates:  Eribulin shows no induction potential for CYP1A, CYP2B6, CYP2C9, CYP2C19, and CYP3A in primary human hepatocytes. Eribulin inhibits CYP3A4 activity in human liver microsomes, but it is unlikely that eribulin will substantially increase the plasma levels of CYP3A4 substrates. No significant inhibition of CYP1A2, CYP2C9, CYP2C19, CYP2D6, or CYP2E1 was detected with eribulin concentrations up to 5 μM in pooled human liver microsomes. In vitro drug interaction studies indicate that eribulin does not inhibit drugs that are substrates of these enzymes and it is unlikely that eribulin will affect plasma levels of drugs that are substrates of CYP enzymes.

    Effect of Transporters on Eribulin: In vitro data suggest that eribulin at clinically relevant concentrations is a substrate of P-gp, but is not a substrate of breast cancer resistance protein (BCRP), multidrug resistance proteins (MRP2, MRP4), bile salt extrusion pump (BSEP), organic anion transporting polypeptides (OATP1B1, OATP1B3), organic anion transporters (OAT1, OAT3), organic cation transporters (OCT1, OCT2), or multidrug and toxin extrusion 1 (MATE1).

    Effect of Eribulin on Transporters: In vitro data suggest that eribulin at clinically relevant concentrations may inhibit P-gp, but does not inhibit BCRP, OATP1B1, OCT1, OAT1, OAT3, or MATE1.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenicity studies have not been conducted with eribulin mesylate.  Eribulin mesylate was not mutagenic in in vitro bacterial reverse mutation assays (Ames test). Eribulin mesylate was positive in mouse lymphoma mutagenesis assays, and was clastogenic in an in vivo rat bone marrow micronucleus assay.

    Fertility studies have not been conducted with eribulin mesylate in humans or animals; however, nonclinical findings in repeat-dose dog and rat toxicology studies suggest that male fertility may be compromised by treatment with eribulin mesylate.  Rats exhibited testicular toxicity (hypocellularity of seminiferous epithelium with hypospermia/aspermia) following dosing with eribulin mesylate at or above 0.43 times the recommended human dose (based on body surface area) given once weekly for 3 weeks, or at or above 0.21 times the recommended human dose (based on body surface area) given once weekly for 3 out of 5 weeks, repeated for 6 cycles. Testicular toxicity was also observed in dogs given 0.64 times the recommended human dose (based on body surface area) weekly for 3 out of 5 weeks, repeated for 6 cycles.

  • 14 CLINICAL STUDIES

    14.1 Metastatic Breast Cancer

    Study 1 was an open-label, randomized, multicenter trial of 762 patients with metastatic breast cancer who received at least two chemotherapeutic regimens for the treatment of metastatic disease and experienced disease progression within 6 months of their last chemotherapeutic regimen. Patients were required to receive prior anthracycline- and taxane-based chemotherapy for adjuvant or metastatic disease. Patients were randomized (2:1) to receive eribulin mesylate injection (n=508) or a single agent therapy selected prior to randomization (control arm, n=254). Randomization was stratified by geographic region, HER2/neu status, and prior capecitabine exposure. Eribulin mesylate injection was administered at a dose of 1.4 mg/m2 on Days 1 and 8 of a 21-day cycle. Eribulin mesylate injection-treated patients received a median of 5 cycles (range: 1 to 23 cycles) of therapy.  Control arm therapy consisted of 97% chemotherapy (26% vinorelbine, 18% gemcitabine, 18% capecitabine, 16% taxane, 9% anthracycline, 10% other chemotherapy), and 3% hormonal therapy. The main efficacy outcome was overall survival.

    Patient demographic and baseline characteristics were comparable between the treatment arms. The median age was 55 (range: 27 to 85 years) and 92% were White. Sixty-four percent of patients were enrolled in North America/Western Europe/Australia, 25% in Eastern Europe/Russia, and 11% in Latin America/South Africa.  Ninety-one percent of patients had a baseline ECOG performance status of 0 or 1. Tumor prognostic characteristics, including estrogen receptor status (positive: 67%, negative: 28%), progesterone receptor status (positive: 49%, negative: 39%), HER2/neu receptor status (positive: 16%, negative: 74%), triple negative status (ER-, PR-, HER2/neu-: 19%), presence of visceral disease (82%, including 60% liver and 38% lung) and bone disease (61%), and number of sites of metastases (greater than two: 50%), were also similar in the eribulin mesylate injection and control arms. Patients received a median of four prior chemotherapy regimens in both arms.

    In Study 1, a statistically significant improvement in overall survival was observed in patients randomized to the eribulin mesylate injection arm compared to the control arm (see Table 5). An updated, unplanned survival analysis, conducted when 77% of events had been observed (see Figure 1), was consistent with the primary analysis. In patients randomized to eribulin mesylate injection, the objective response rate by the RECIST criteria was 11% (95% CI: 8.6%, 14.3%) and the median response duration was 4.2 months (95% CI: 3.8, 5.0 months).

    14.2 Liposarcoma

    The efficacy and safety of eribulin mesylate injection were evaluated in Study 2, an open-label, randomized (1:1), multicenter, active-controlled trial.  Eligible patients were required to have unresectable, locally advanced or metastatic liposarcoma or leiomyosarcoma, at least two prior systemic chemotherapies (one of which must have included an anthracycline), and disease progression within 6 months of the most recent chemotherapy regimen.  Patients were randomized to eribulin mesylate injection 1.4 mg/m2 administered intravenously on Days 1 and 8 of a 21-day cycle or to dacarbazine at a dose of 850 mg/m2, 1000 mg/m2, or 1200 mg/m2 administered intravenously every 21 days (dacarbazine dose was selected by the investigator prior to randomization).  Treatment continued until disease progression or unacceptable toxicity.  Randomization was stratified by histology (liposarcoma or leiomyosarcoma), number of prior therapies (2 vs. > 2), and geographic region (U.S. and Canada vs. Western Europe, Australia, and Israel vs. Eastern Europe, Latin America, and Asia).  The major efficacy outcome measure was overall survival (OS). Additional efficacy outcome measures were progression-free survival (PFS) and confirmed objective response rate (ORR) as assessed by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST v1.1).  Patients in the dacarbazine arm were not offered eribulin mesylate injection at the time of disease progression.

    A total of 446 patients were randomized, 225 to the eribulin mesylate injection arm and 221 to the dacarbazine arm. The median age was 56 years (range: 24 to 83); 33% were male; 73% were White; 44% had ECOG performance status (PS) 0 and 53% had ECOG PS 1; 68% had leiomyosarcoma and 32% had liposarcoma; 39% were enrolled in U.S. and Canada (Region 1) and 46% were enrolled in Western Europe, Australia, and Israel (Region 2); and 47% received more than two prior systemic chemotherapies.  The most common (>40%) prior systemic chemotherapies were doxorubicin (90%), ifosfamide (62%), gemcitabine (59%), trabectedin (50%), and docetaxel (48%).

    Of the 143 patients with liposarcoma, the median age was 55 years (range: 32 to 83); 62% were male, 72% were White; 41% had ECOG PS of 0 and 53% had ECOG PS of 1; 35% were enrolled in Region 1 and 51% were enrolled in Region 2; and 44% received more than two prior systemic chemotherapies.  The distribution of subtypes of liposarcoma, based on local histologic assessment, were 45% dedifferentiated, 37% myxoid/round cell, and 18% pleomorphic.

    Study 2 demonstrated a statistically significant improvement in OS in patients randomized to eribulin mesylate injection compared with dacarbazine (see Table 6).  There was no significant difference in progression-free survival in the overall population. Treatment effects of eribulin mesylate injection were limited to patients with liposarcoma based on pre-planned, exploratory subgroup analyses of OS and PFS (see Tables 6 and 7 and Figure 2). There was no evidence of efficacy of eribulin mesylate injection in patients with advanced or metastatic leiomyosarcoma in Study 2 (see Table 7).
