3月28日，新型抗癌药物Halaven(甲磺酸艾日布林注射液)获得欧洲委员会批准，用于治疗既往接受至少两种化疗方案的局部晚期或转移性乳腺癌患者。 甲磺酸艾日布林是一种从黑色软海绵中提取的一种有化疗活性化合物的合成制剂。甲磺酸艾日布林是一种微管抑制剂，能抑制癌细胞生长。适用于既往接受至少两种化疗方案的转移乳癌患者。既往治疗应已包括一种蒽环类和一种紫杉烷类或者辅助或转移情况。 值得注意的是，在接受甲磺酸艾日布林治疗之前，患者应先接受以前的以蒽环类为基础和以紫杉烷为基础的化疗方案治疗早期或晚期乳腺癌。 目前，乳腺癌患者的治疗药物应包括蒽环类和紫杉类，除非患者不适合应用这些药物进行治疗。甲磺酸艾日布林是第一个可以明显改善晚期乳腺癌患者整体生存率的单制剂治疗药物。与目前的治疗方案相比，甲磺酸艾日布林可以显著改善患者的整体存活率。 早在2010年11月及2011年2月，甲磺酸艾日布林分别被美国和新加坡批准上市，并已在美国正式推出。欧洲委员会为世界上第三位批准的国家，日本、瑞士和加拿大等国家目前正在审查批准申请。 欧盟委员会的批准意味着在欧盟的患者将很快能够受益于该治疗药物。卫材计划先在英国推出Halaven，随后在其他国家实施。甲磺酸艾日布林的上市，将为晚期乳腺癌患者提供更佳的选择，因为研究显示，其可以使晚期乳腺癌患者平均寿命延长超过2个月。 Halaven 0.44mg/ml solution for injection 1. Name of the medicinal product HALAVEN 0.44 mg/ml solution for injection 2. Qualitative and quantitative composition One ml contains eribulin mesilate equivalent to 0.44 mg eribulin. Each 2 ml vial contains eribulin mesilate equivalent to 0.88 mg eribulin. For the full list of excipients, see section 6.1. 3. Pharmaceutical form Solution for injection. Clear, colourless aqueous solution. 4. Clinical particulars 4.1 Therapeutic indications HALAVEN is indicated for the treatment of patients with locally advanced or metastatic breast cancer who have progressed after at least one chemotherapeutic regimen for advanced disease (see section 5.1). Prior therapy should have included an anthracycline and a taxane in either the adjuvant or metastatic setting unless patients were not suitable for these treatments. 4.2 Posology and method of administration HALAVEN should be administered in units specialised in the administration of cytotoxic chemotherapy and only under the supervision of a qualified physician experienced in the appropriate use of cytotoxic medicinal products. Posology The recommended dose of eribulin as the ready to use solution is 1.23 mg/m2 which should be administered intravenously over 2 to 5 minutes on Days 1 and 8 of every 21-day cycle. Please note: In the EU the recommended dose refers to the base of the active substance (eribulin). Calculation of the individual dose to be administered to a patient must be based on the strength of the ready to use solution that contains 0.44 mg/ml eribulin and the dose recommendation of 1.23 mg/m2. The dose reduction recommendations shown below are also shown as the dose of eribulin to be administered based on the strength of the ready to use solution. In the pivotal EMBRACE trial, the corresponding publication and in some other regions e.g. the US and Switzerland, the recommended dose is based on the salt form (eribulin mesilate). Patients may experience nausea or vomiting. Antiemetic prophylaxis including corticosteroids should be considered. Dose delays during therapy The administration of HALAVEN should be delayed on Day 1 or Day 8 for any of the following: - Absolute neutrophil count (ANC) < 1 x 109/l - Platelets < 75 x 109/l - Grade 3 or 4 non-hematological toxicities. Dose reduction during therapy Dose reduction recommendations for retreatment are shown in the following table. Dose reduction recommendations Do not re-escalate the eribulin dose after it has been reduced. Patients with hepatic impairment Impaired liver function due to metastases: The recommended dose of eribulin in patients with mild hepatic impairment (Child-Pugh A) is 0.97 mg/m2 administered intravenously over 2 to 5 minutes on Days 1 and 8 of a 21-day cycle. The recommended dose of eribulin in patients with moderate hepatic impairment (Child-Pugh B) is 0.62 mg/m2 administered intravenously over 2 to 5 minutes on Days 1 and 8 of a 21-day cycle. Severe hepatic impairment (Child-Pugh C) has not been studied but it is expected that a more marked dose reduction is needed if eribulin is used in these patients. Impaired liver function due to cirrhosis: This patient group has not been studied. The doses above may be used in mild and moderate impairment but close monitoring is advised as the doses may need readjustment. Patients with renal impairment Patients with severely impaired renal function (creatinine clearance <40 ml/min) may need a reduction of the dose. The optimal dose for this patient groups remains to be established. Caution and close safety monitoring as advised. No specific dose adjustments are recommended for patients with mild to moderate renal impairment but close safety monitoring is advised. (See section 5.2) Elderly patients No specific dose adjustments are recommended based on the age of the patient (see section 4.8). Paediatric population There is no relevant use of HALAVEN in children and adolescents in the indication of breast cancer. Method of administration The dose may be diluted in up to 100 ml of sodium chloride 9 mg/ml (0.9%) solution for injection. It should not be diluted in glucose 5% infusion solution. For instructions on the dilution of the medicinal product before administration, see section 6.6. Good peripheral venous access, or a patent central line, should be ensured prior to administration. There is no evidence that eribulin mesilate is a vesicant or an irritant. In the event of extravasation, treatment should be symptomatic. For information relevant to the handling of cytotoxic drugs see section 6.6. 4.3 Contraindications - Hypersensitivity to the active substance or to any of the excipients listed in section 6.1 - Breast-feeding 4.4 Special warnings and precautions for use Haematology Myelosuppression is dose dependent and primarily manifested as neutropenia (section 4.8). Monitoring of complete blood counts should be performed on all patients prior to each dose of eribulin. Treatment with eribulin should only be initiated in patients with ANC values ≥ 1.5 x 109/l and platelets > 100 x 109/l. Febrile neutropenia occurred in < 5% of breast cancer patients treated with eribulin. Patients experiencing febrile neutropenia, severe neutropenia or thrombocytopenia, should be treated according to the recommendations in section 4.2. Patients with ALT or AST >3 x ULN experienced a higher incidence of Grade 4 neutropenia and febrile neutropenia. Although data are limited, patients with bilirubin >1.5 x ULN also have a higher incidence of Grade 4 neutropenia and febrile neutropenia. Severe neutropenia may be managed by the use of G-CSF or equivalent at the physician's discretion in accordance with relevant guidelines (see section 5.1). Peripheral neuropathy Patients should be closely monitored for signs of peripheral motor and sensory neuropathy. The development of severe peripheral neurotoxicity requires a delay or reduction of dose (see section 4.2) In clinical trials, patients with pre-existing neuropathy greater than Grade 2 were excluded. However, patients with pre-existing neuropathy Grade 1 or 2 were no more likely to develop new or worsening symptoms than those who entered the study without the condition. 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 or concomitant treatment with medicinal products known to prolong the QT interval, including Class Ia and III antiarrhythmics, and electrolyte abnormalities. Hypokalemia or hypomagnesemia should be corrected prior to initiating HALAVEN and these electrolytes should be monitored periodically during therapy. Eribulin should be avoided in patients with congenital long QT syndrome. Use in combination with anti-HER2 therapy There is no experience of using eribulin in combination with anti-HER2 therapy in clinical trials. Excipients This medicinal product contains small amounts of ethanol (alcohol), less than 100 mg per dose. 4.5 Interaction with other medicinal products and other forms of interaction Eribulin is mainly (up to 70%) eliminated through biliary excretion. The transport protein involved in this process is unknown. Complete inhibition of the transport could in theory give rise to a more than 3-fold increase in plasma concentrations. It is not recommended to use substances which are inhibitors of hepatic transport proteins such as organic anion-transporting proteins (OATPs) and multidrug resistant proteins (MRPs) etc concomitantly with eribulin. Inhibitors of such transporters include but are not limited to: cyclosporine, ritonavir, saquinavir, lopinavir and certain other protease inhibitors, efavirenz, emtricitabine, quinine, quinidine, disopyramide etc. It cannot be excluded that concomitant treatment with inducing substances, such as carbamazepine, phenytoin, St John´s wort (Hypericum perforatum), could give rise to reduced plasma concentrations of eribulin, and co-administration with inducers should be carried out with caution considering a potential risk for reduced drug efficacy. No marked effects on eribulin exposure (AUC and Cmax) were observed during treatment with the CYP3A4 inducer rifampicin. However, rifampicin may due to its transporter inhibitory property counteract its possible inducing effect on eribulin elimination. Therefore, the effect of rifampicin may not presently be extrapolated to other inducers. No drug-drug interactions are expected with CYP3A4 inhibitors. Eribulin exposure (AUC and Cmax) was unaffected by ketoconazole, a CYP3A4 and P glycoprotein (Pgp) inhibitor. Effects of eribulin on the pharmacokinetics of other drugs In vitro data indicate that eribulin is a mild inhibitor of the important drug metabolising enzyme CYP3A4. No in vivo data are available. Caution and monitoring for adverse effects is recommended with concomitant use of substances that have a narrow therapeutic window and that are eliminated mainly via CYP3A4-mediated metabolism (e.g. alfentanil, cyclosporine, ergotamine, fentanyl, pimozide, quinidine, sirolimus, tacrolimus). Eribulin does not inhibit the CYP enzymes CYP1A2, 2B6, 2C8, 2C9, 2C19, 2D6 or 2E1 at relevant clinical concentrations. 4.6 Fertility, pregnancy and lactation Pregnancy There are no data from the use of eribulin in pregnant women. Eribulin is embryotoxic, foetotoxic, and teratogenic in rats. HALAVEN should not be used during pregnancy unless clearly necessary and after a careful consideration of the needs of the mother and the risk to the foetus. Women of childbearing potential must be advised to avoid becoming pregnant whilst they or their male partner are receiving HALAVEN and have to use effective contraception during and up to 3 months after treatment. Breast-feeding It is unknown whether eribulin/metabolites are excreted in human or animal breast milk. A risk to newborns/infants cannot be excluded and therefore HALAVEN must not be used during breast-feeding (see section 4.3). Fertility Testicular toxicity has been observed in rats and dogs (see section 5.3). Male patients should seek advice on conservation of sperm prior to treatment because of the possibility of irreversible infertility due to therapy with HALAVEN. 4.7 Effects on ability to drive and use machines HALAVEN may cause adverse reactions such as tiredness and dizziness which may lead to a minor or moderate influence on the ability to drive or use machines. Patients should be advised not to drive or use machines if they feel tired or dizzy. 4.8 Undesirable effects Summary of safety profile The most commonly reported undesirable effects related to HALAVEN, are bone marrow suppression manifested as neutropenia, leucopenia, anaemia, thrombocytopenia with associated infections. New onset or worsening of pre-existing peripheral neuropathy has also been reported. Gastrointestinal toxicities, manifested as anorexia, nausea, vomiting, diarrhoea, constipation, and stomatitis are among reported undesirable effects. Other undesirable effects include fatigue, alopecia, increased liver enzymes, sepsis and musculoskeletal pain syndrome. Tabulated list of adverse reactions Unless otherwise noted, the table shows the incidence rates of adverse events observed in 1503 breast cancer patients who received the recommended dose in five Phase 2 and two Phase 3 studies. Frequency categories are defined as: very common (≥ 1/10), common (≥ 1/100 to < 1/10), uncommon (≥ 1/1,000 to < 1/100), rare (≥ 1/10,000 to < 1/1,000) and very rare (< 1/10,000). Within each frequency grouping, undesirable effects are presented in order of decreasing frequency. Where Grade 3 or 4 reactions occurred, the actual total frequency and the frequency of Grade 3 or 4 reactions are given. a Includes 1 or 2 Grade 5 b From spontaneous reporting c Includes preferred terms of peripheral neuropathy, peripheral motor neuropathy, polyneuropathy, paraesthesia, peripheral sensory neuropathy, peripheral sensorimotor neuropathy and demyelinating polyneuropathy d No Grade 4 Selected adverse reactions Neutropenia The neutropenia observed was reversible and not cumulative; the mean time to nadir was 13 days and the mean time to recovery from severe neutropenia (< 0.5 x 109/l) was 8 days. Neutrophil counts of < 0.5 x 109/l that lasted for more than 7 days occurred in 13% of breast cancer patients treated with eribulin in the EMBRACE study. Severe neutropenia may be managed by the use of G-CSF or equivalent at the physician's discretion in accordance with relevant guidelines. 18% of breast cancer patients treated in a phase 3 study with eribulin received G-CSF. Neutropenia resulted in discontinuation in < 1% of patients receiving eribulin. Disseminated intravascular coagulation Cases of disseminated intravascular coagulation have been reported, typically in association with neutropenia and/or sepsis. Peripheral neuropathy In the 1503 breast cancer patients the most common adverse reaction resulting in discontinuation of treatment with eribulin was peripheral neuropathy ( 3.3%). The median time to Grade 2 peripheral neuropathy was 85.5 days (post 4 cycles). Development of Grade 3 or 4 peripheral neuropathy occurred in 7.7% of eribulin treated breast cancer patients. In clinical trials, patients with pre-existing neuropathy were as likely to develop new or worsening symptoms as those who entered the study without the condition. In patients with pre-existing Grade 1 or 2 peripheral neuropathy the frequency of treatment-emergent Grade 3 peripheral neuropathy was 14%. Hepatoxicity In some patients with normal/abnormal liver enzymes prior treatment with eribulin, increased levels of liver enzymes have been reported with initiation of eribulin treatment. Such elevations appeared to have occurred early with eribulin treatment in cycle 1 – 2 for the majority of these patients and whilst thought likely to be a phenomenon of adaptation to eribulin treatment by the liver and not a sign of significant liver toxicity in most patients , hepatotoxicity has also been reported. Special populations Elderly population Of the 1503 breast cancer patients treated with the recommended dose of eribulin, 209 patients (13.9%) were > 65 - 75 years of age and 24 patients (1.6%) were > 75 years of age. The safety profile of eribulin in elderly patients (> 65 years of age) was similar to that of patients ≤ 65 years of age except for asthenia/fatigue which showed an increasing trend with age. No dose adjustments are recommended for the elderly population. Patients with hepatic impairment Patients with ALT or AST > 3 x ULN experienced a higher incidence of Grade 4 neutropenia and febrile neutropenia. Although data are limited, patients with bilirubin > 1.5 x ULN also have a higher incidence of Grade 4 neutropenia and febrile neutropenia (see also sections 4.2 and 5.2). Reporting of suspected adverse reactions Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme Website: www.mhra.gov.uk/yellowcard 4.9 Overdose In one case of overdose the patient inadvertently received 7.6 mg of eribulin (approximately 4 times the planned dose) and subsequently developed a hypersensitivity reaction (Grade 3) on Day 3 and neutropenia (Grade 3) on Day 7. Both adverse reactions resolved with supportive care. There is no known antidote for eribulin overdose. In the event of an overdose, the patient should be closely monitored. Management of overdose should include supportive medical interventions to treat the presenting clinical manifestations. 5. Pharmacological properties 5.1 Pharmacodynamic properties Pharmacotherapeutic group: Other antineoplastic agents, ATC code: L01XX41 HALAVEN (eribulin mesilate) is a non-taxane, microtubule dynamics inhibitor belonging to the halichondrin class of antineoplastic agents. It is a structurally simplified synthetic analogue of halichondrin B, a natural product isolated from the marine sponge Halichondria okadai. Eribulin inhibits the growth phase of microtubules without affecting the shortening phase and sequesters tubulin into non-productive 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. Clinical efficacy The efficacy of HALAVEN in breast cancer is primarily supported by two randomized Phase 3 comparative studies. The 762 patients in the pivotal Phase 3 EMBRACE study (Study 305) had locally recurrent or metastatic breast cancer, and had previously received at least two and a maximum of five chemotherapy regimens, including an anthracycline and a taxane (unless contraindicated). Patients must have progressed within 6 months of their last chemotherapeutic regimen. The HER2 status of the patients was: 16.1% positive, 74.2% negative and 9.7% unknown, whilst 18.9% of patients were triple negative. They were randomized 2:1 to receive either HALAVEN, or treatment of physician's choice (TPC), which consisted of 97% chemotherapy (26% vinorelbine, 18% gemcitabine, 18% capecitabine, 16% taxane, 9% anthracycline, 10% other chemotherapy), or 3% hormonal therapy. The study met its primary endpoint with an overall survival result that was statistically significantly better in the eribulin group compared to TPC at 55% of events. This result was confirmed with an updated overall survival analysis carried out at 77% of events. Study 305 - Updated Overall Survival ( ITT Population) By independent review, the median progression free survival (PFS) was 3.7 months for eribulin compared to 2.2 months for the TPC arm (HR 0.865, 95% CI: 0.714, 1.048, p=0.137). In response evaluable patients, the objective response rate by the RECIST criteria was 12.2% (95% CI: 9.4%, 15.5%) by independent review for the eribulin arm compared to 4.7% (95% CI: 2.3%, 8.4%) for the TPC arm. The positive effect on OS was seen in both taxane-refractory and non-refractory groups of patients . In the OS update, the HR for eribulin versus TPC was 0.90 (95% CI: 0.71, 1.14) in favour of eribulin for taxane-refractory patients and 0.73 (95% CI: 0.56, 0.96) for patients not taxane-refractory. The positive effect on OS was seen both in capecitabine-naïve and in capecitabine pre-treated patient groups. The updated OS analysis showed a survival benefit for the eribulin group compared to TPC both in capecitabine pre-treated patients with a HR of 0.787 (95% CI: 0.645, 0.961), and for the capecitabine-naïve patients with a corresponding HR of 0.865 (95% CI: 0.606, 1.233). The second Phase 3 study in earlier line metastatic breast cancer, Study 301, was an open-label, randomized, study in patients (n=1102) with locally advanced or metastatic breast cancer to investigate the efficacy of HALAVEN monotherapy compared to capecitabine monotherapy in terms of OS and PFS as co-primary endpoint. Patients had previously received up to three prior chemotherapy regimens, including both an anthracycline and a taxane and a maximum of two for advanced disease, with the percentage who had received 0, 1 or 2 prior chemotherapy treatments for metastatic breast cancer being 20.0%, 52.0% or 27.2% respectively. The HER2 status of the patients was: 15.3% positive, 68.5% negative and 16.2% unknown, whilst 25.8% of patients were triple negative. Study 301 - Overall Survival (ITT Population) Progression free survival assessed by independent review was similar between eribulin and capecitabine with medians of 4.1 months vs 4.2 months (HR 1.08; [95% CI: 0.932, 1.250]) respectively. Objective response rate as assessed by independent review was also similar between eribulin and capecitabine; 11.0% (95% CI: 8.5, 13.9) in the eribulin group and 11.5% (95% CI: 8.9, 14.5) in the capecitabine group. The overall survival in patients in HER2 negative and HER2 positive patients in the eribulin and control groups in Study 305 and Study 301 is shown below: Paediatric population The European Medicines Agency has waived the obligation to submit the results of studies with eribulin in all subsets of the paediatric population in the indication of breast cancer. 5.2 Pharmacokinetic properties Distribution The pharmacokinetics of eribulin are characterized by a rapid distribution phase followed by a prolonged elimination phase, with a mean terminal half-life of approximately 40 h. It has a large volume of distribution (range of means 43 to 114 l/m2). Eribulin is weakly bound to plasma proteins. The plasma protein binding of eribulin (100-1000 ng/ml) ranged from 49% to 65% in human plasma. Biotransformation 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. Elimination Eribulin has a low clearance (range of means 1.16 to 2.42 l/h/m2). No significant accumulation of eribulin is observed on weekly administration. The pharmacokinetic properties are not dose or time dependent in the range of eribulin doses of 0.22 to 3.53 mg/m2. Eribulin is eliminated primarily by biliary excretion. The transport protein involved in the excretion is presently unknown. Preclinical in vitro studies indicate that eribulin is transported by Pgp. However it has been shown that at clinically relevant concentrations eribulin is not a Pgp inhibitor in vitro. Additionally, in vivo, concomitant administration of ketoconazole, a Pgp inhibitor, has no effect on eribulin exposure (AUC and Cmax). In vitro studies have also indicated that eribulin is not a substrate for OCT1. After administration of 14C-eribulin to patients, approximately 82% of the dose was eliminated in faeces and 9% in urine indicating that renal clearance is not a significant route of eribulin elimination. Unchanged eribulin represented most of the total radioactivity in faeces and urine. Hepatic impairment A study evaluated the PK of eribulin in patients with mild (Child-Pugh A; n=7) and moderate (Child-Pugh B; n=4) hepatic impairment due to liver metastases. Compared to patients with normal hepatic function (n=6), eribulin exposure increased 1.8-fold and 3-fold in patients with mild and moderate hepatic impairment, respectively. Administration of HALAVEN at a dose of 0.97 mg/m2 to patients with mild hepatic impairment and 0.62 mg/m2 to patients with moderate hepatic impairment resulted in a somewhat higher exposure than after a dose of 1.23 mg/m2 to patients with normal hepatic function. HALAVEN was not studied in patients with severe hepatic impairment (Child-Pugh C). There is no study in patients with hepatic impairment due to cirrhosis. See section 4.2 for dosage recommendation. Renal impairment Data in patients with different degrees of impaired renal function showed that the exposure of eribulin in patients with mild to moderate renal impairment (creatinine clearance ≥ 40 to 80 ml/min) was increased in some patients, as compared to patients with normal renal function. The mean exposure in patients with severe impairment was increased by 75% (creatinine clearance < 40 ml/min, n=4). See section 4.2 for treatment recommendations. 5.3 Preclinical safety data Eribulin was not mutagenic in vitro in the bacterial reverse mutation assay (Ames test). Eribulin was positive in the mouse lymphoma mutagenesis assay and was clastogenic in the in vivo rat micronucleus assay. No carcinogenicity studies have been conducted with eribulin. A fertility study was not conducted with eribulin, but based on non-clinical findings in repeated-dose studies where testicular toxicity was observed in both rats (hypocellularity of seminiferous epithelium with hypospermia/aspermia) and dogs, male fertility may be compromised by treatment with eribulin. An embryofoetal development study in rat confirmed the developmental toxicity and teratogenic potential of eribulin. Pregnant rats were treated with eribulin mesilate equivalent to 0.009, 0.027, 0.088 and 0.133 mg/kg eribulin at gestation days 8, 10 and 12. Dose related increased number of resorptions and decreased foetal weight were observed at doses ≥ 0.088 mg/kg and increased incidence of malformations (absence of lower jaw, tongue, stomach and spleen) was recorded at 0.133 mg/kg. 6.
