4. 禁忌证
(1)中性粒细胞计数of ≤1,500/mm3。
(2)对JEVTANA或山梨醇80严重超敏性史。
5. 警告和注意事项
5.1 中性粒细胞减少
5例患者经受致命性感染不良事件(脓毒血症或败血症休克)。所有都有4级中性粒细胞减少和1例有发热性中性粒细胞减少。另一例患者死亡归咎于中性粒细胞减少无文件记载的感染。
伴随JEVTANA使用可给予G-CSF减低中性粒细胞减少并发症的风险。用G-CSF主要预防应考虑患者有高危临床特点(年龄> 65岁,体能状态差,既往发热性中性粒细胞减少发作,既往用广泛复式端口,营养状态差,或其它严重合并症)叠加增加来自长期中性粒细胞减少并发症。在中性粒细胞减少并发症风险增加时所有患者中应考虑治疗性用G-CSF和继发预防。
在疗程1和每个治疗疗程前在每周基础上监查全细胞计数很重要,其后可调整剂量,如需要时[见剂量和给药方法(2.2)]。
嗜中性粒细胞 ≤ 1,500/mm3患者不应给予JEVTANA [见禁忌证(4)]。
如某患者经受发热性中性粒细胞减少或长期中性粒细胞减少(大于一周)不管适当药物(如,G-CSF),应减低JEVTANA剂量[见剂量和给药方法(2.2)]。只有当中性粒细胞计数恢复至水平 > 1,500/mm3患者才能重新开始用JEVTANA治疗[见禁忌证(4)]。
5.2 超敏性反应
开始输注JEVTANA前所有患者应预先给药[见剂量和给药方法(2.3)]。应严密观察患者有无超敏性反应,特别是第一次和第二次输注时。可能在开始输注JEVTANA几分钟内发生超敏性反应,因此应能得到治疗低血压和支气管痉挛的设备和仪器。可能发生严重超敏性反应和可能包括普遍性皮疹/红斑,低血压和支气管痉挛。严重超敏性反应需要立即停止JEVTANA输注和适当治疗。有严重超敏性反应史患者不应再用JEVTANA[见禁忌证(4)].
5.3 胃肠道症状
恶心, 呕吐和严重腹泻,有时,可能发生。在随机化临床试验中发生与腹泻和电解质不平衡相关死亡。对严重腹泻和电解质不平衡可能需要强化措施。需要时应用补液,抗-腹泻或抗吐药治疗患者。如果患者经受级别 ≥ 3 腹泻可能需要治疗延缓或减低剂量[见剂量和给药方法(2.2)]。
5.4 肾衰
在随机化临床试验中报道肾衰,包括4例有致命结局。大多数病例发生伴随脓毒血症,脱水,或尿路梗阻[见不良反应(6.1)]。有些死亡由于肾衰没有明确的病因。应采取适当措施确定肾衰的原因和积极治疗。
5.5 老年患者
在随机化临床试验中,3/131例(2%)患者< 65岁和15/240例(6%)≥65岁在末次cabazitaxel给药30天内死于除了疾病进展以外的其它原因。患者≥ 65岁更可能经受某些不良反应,包括中性粒细胞减少和发热性中性粒细胞减少[见不良反应(6)和在特殊人群中使用(8.5)]。
5.6 肝损伤
未曾为JEVTANA进行专门肝损伤试验。有肝功能受损患者(总胆红素 ≥ ULN,或AST和/或ALT ≥ 1.5 × ULN) 被从随机化临床试验排除。
Cabazitaxel在肝脏内被广泛代谢,和肝损伤很可能增加cabazitaxel浓度。
在患者接受属于和JEVTANA同类其它药物时,肝损伤增加严重和危及生命并发症的风险。有肝损伤患者(总胆红素 ≥ ULN。或AST和/或ALT ≥ 1.5 × ULN)不应给予JEVTANA。
5.7 妊娠
妊娠类别D。
当给予妊娠妇女时JEVTANA可导致胎儿伤害。在大鼠和兔在非临床研究中,在显著低于推荐人剂量水平时预期的暴露时,cabazitaxel 是胚胎毒性,胎畜毒性,和堕胎药。
用JEVTANA妊娠妇女中无适当和对照良好研究。如果妊娠期间使用此药,或如患者当用此药时变成怀孕,应告知患者对胎儿的潜在危害。有生育潜力妇女用JEVTANA治疗期间应劝告避免成为怀孕[见特殊人群中使用(8.1)]。
6. 不良反应
在说明书另一节内将更详细讨论以下严重不良反应:
1)中性粒细胞减少[见警告和注意事项(5.1)]。
2)超敏性反应[见警告和注意事项(5.2)]。
3)胃肠道症状[见警告和注意事项(5.3)]。
4)肾衰[见警告和注意事项(5.4)].
6.1 临床经验
因为临床试验是在广泛不同条件下进行,某药临床试验观察到的不良反应率不能与另一药物临床试验中的发生率直接比较而且可能不反映实践中观察到的发生率。
在一项随机化试验中在371例用激素难治转移前列腺癌治疗患者与米托蒽醌加泼尼松比较评价JEVTANA与泼尼松[prednisone]联用的安全性。
JEVTANA-治疗患者报道由于末次研究药物给药30天内除了疾病进展引起死亡18例(5%)和米托蒽醌-治疗患者为3(< 1%)。在JEVTANA-治疗患者中最常见致命不良反应是感染(n=5)和肾衰(n=4)。大多数(4/5患者)的致命感染相关不良反应发生在单剂量JEVTANA后。在JEVTANA-治疗患者中其它致命不良反应包括心室纤颤,脑出血,和呼吸困难。
最常见(≥ 10%)1-4级不良反应是贫血、白细胞减少、中性粒细胞减少、血小板减少、腹泻、疲劳、恶心、呕吐、便秘、虚弱、腹痛、血尿、背痛、厌食、周围神经病变、发热、呼吸困难、味觉障碍、咳嗽、关节痛、和脱发。
接受JEVTANA患者中最常见(≥ 5%)3-4级不良反应是中性粒细胞减少、白细胞减少、贫血、发热性中性粒细胞减少、腹泻、疲劳、和虚弱。
接受JEVTANA患者18%发生由于不良药物反应停止治疗和接受米托蒽醌患者为8%。JEVTANA组中导致停止治疗的最常见不良反应是中性粒细胞减少和肾衰。JEVTANA-治疗患者报道12%减低剂量和米托蒽醌-治疗患者为4%。JEVTANA-治疗患者报道28%延迟给药而米托蒽醌-治疗患者为15%。
中性粒细胞减少和伴临床事件:
5例患者经受致命性感染不良事件(脓毒血症或败血症休克)。所有有4级中性粒细胞减少和1例有发热性中性粒细胞减少。另一例患者的死亡归咎于中性粒细胞减少无记载的感染。22例(6%)患者由于中性粒细胞减少,发热性中性粒细胞减少,感染,或脓毒血症停止JEVTANA治疗。JEVTANA组中导致停止治疗最常见不良反应是中性粒细胞减少(2%)。
血尿:
血尿的不良事件,包括那些需要医学干预,在JEVTANA-治疗患者中更常见。JEVTANA-治疗患者级别 ≥ 2 血尿发生率是6%和米托蒽醌-治疗患者为2%。在组间伴随血尿其它因子被很好平衡和对JEVTANA组血尿率增加不负责任.
肝实验室异常:
3-4级增加的AST, 增加的ALT,和增加的胆红素的发生率各≤ 1%。
老年人群:
下列1-4级不良反应被报道,65岁或以上患者与较年轻患者比较发生率较高≥ 5%分别为:疲劳(40%相比30%),中性粒细胞减少(97%相比89%),虚弱(24%相比15%),发热(15%相比8%),眩晕(10%相比5%),泌尿道感染(10%相比3%)和脱水(7%相比2%)。
≥ 65岁患者与较年轻患者比较下列3-4级不良反应的发生率较高:中性粒细胞减少(87%相比74%),和发热性中性粒细胞减少(8%相比6%)[见特殊人群中使用(8.5)].
8.药物相互作用
同时使用诱导或抑制CYP3A药物的患者中谨慎使用本品。
12. 临床药理学
12.1 作用机制
Cabazitaxel是一种微管抑制剂。Cabazitaxel与微管蛋白结合和促使它组装至微管同时抑制微管分解,这导致微管稳定化,导致细胞功能有丝分裂和分裂间期的抑制。
12.2 药效学
Cabazitaxel对小鼠中移植的人晚期瘤显示抗肿瘤活性。Cabazitaxel在多西紫杉醇[docetaxel]-敏感肿瘤有活性。此外,在对化疗包括多西紫杉醇不敏感肿瘤模型中cabazitaxel显示活性。
12.3 药代动力学
在170例实体瘤患者中进行一项群体药代动力学分析剂量范围从10至30 mg/m2 每周或每三周.
吸收
根据群体药代动力学分析, 静脉给予cabazitaxel 25 mg/m2 每三周后,在转移前列腺癌患者平均Cmax为226 ng/mL (CV 107%)和1小时输注结束时达到(Tmax),转移前列腺癌患者平均AUC为991 ng?h/mL(CV 34%)。晚期实体瘤患者中从10至30 mg/m2未观察到重要偏离剂量正比例。
分布
稳态分布容积(Vss)为4,864 L(对一例BSA中位数1.84 m2患者为2,643 L/m2)。体外,cabazitaxel与血清蛋白的结合为89至92%和至浓度50,000 ng/mL仍未饱和,已覆盖在临床试验中观察到的最高浓度。Cabazitaxel主要结合至人血清白蛋白(82%)和脂蛋白(对HDL88%,对LDL70%,和对VLDL56%)。在人血中体外血-与-血浆浓度比范围从0.90至0.99,表明cabazitaxel是在血液和血浆等同分布。
代谢
Cabazitaxel在肝中被广泛代谢(> 95%),主要被CYP3A4/5同工酶(80%至90%),和被CYP2C8至较低程度。
Cabazitaxel是人血浆主要循环部分。在血浆中被检出7个代谢物(包括来自O-托甲基化作用的3个活性代谢物),主要一个占cabazitaxel暴露的5%。大约20个左右cabazitaxel的代谢物排泄至人尿和粪。
根据体外研究,cabazitaxel抑制其它CYP同工酶底物的药物(1A2,-2B6,-2C9,-2C8,-2C19,-2E1,-2D6,和3A4/5)的潜能低。此外,在体外,cabazitaxel不诱导 CYP同工酶。
消除
静脉输注[14C]-cabazitaxel 25 mg/m2后1小时,2周内给药剂量约80%被消除。Cabazitaxel主要是如许多代谢物在粪中排泄(剂量的76%);而cabazitaxel和代谢物的肾排泄占剂量的3.7%(尿中2.3%为未变化药)。
在转移前列腺癌患者中根据群体药代动力学分析,cabazitaxel血浆清除率为48.5 L/h(CV 39%;对一例BSA中位数1.84 m2患者为26.4 L/h/m2)。静脉输注后1小时,血浆cabazitaxel浓度可用一个三房室药代动力学模型描述,有α-,β-,和γ-半衰期分别为4分钟,2小时,和95小时。
肾损伤
Cabazitaxel很小通过肾排泄。未曾在肾损伤患者中用cabazitaxel进行正式药代动力学试验。在170例患者包括14患者有中度肾损伤(30 mL/min ≤ CLcr < 50 mL/min)和59例轻度肾损伤患者(50 mL/min ≤ CLcr < 80 mL/min)进行群体药代动力学分析显示轻至中度肾损伤对cabazitaxel的药代动力学没有有意义的影响。不能得到严重肾损伤或终末肾病患者的资料[见特殊人群中的使用(8.6)]。
肝损伤
未曾在肝损伤患者中进行正式试验。因为cabazitaxel在肝中被广泛代谢,肝损伤可能增加cabazitaxel浓度[见警告和注意事项(5.6),和特殊人群中的使用(8.7)]。
药物相互作用
因为在体外cabazitaxel主要被CYP3A代谢,强CYP3A诱导剂或抑制剂预期影响cabazitaxel的药代动力学。
每天给予10 mg泼尼松或泼尼松龙[prednisolone]不影响cabazitaxel的药代动力学。
在体外,cabazitaxel不抑制多药抗药蛋白1(MRP1)或2(MRP2)。在体外cabazitaxel抑制P-gp和BRCP的转运,在浓度至少是在临床情况中观察到的38倍。所以,在体内25 mg/m2剂量时,可能没有cabazitaxel抑制MRPs,Pgp,或BCRP的风险。
在体外,cabazitaxel是P-gp的底物,但不是MRP1,MRP2,或BCRP的底物。
13 非临床毒理学
13.1 癌发生,突变发生,生育力损伤
未曾进行长期动物研究评价致癌性cabazitaxel潜能。
Cabazitaxel在体内微核试验中对诱裂发生阳性,在大鼠中在剂量 ≥ 0.5 mg/kg时诱导微核增加。在体外试验在人淋巴细胞有或无代谢激活Cabazitaxel 增加数值畸变尽管未观察到结构畸变的诱导作用。Cabazitaxel在细菌回复突变(Ames)试验不诱导突变。体内遗传毒性阳性发现与化合物药理学活性一致(抑制微管解聚)。
在人中Cabazitaxel可能损伤生育力。在雌性大鼠中cabazitaxel剂量0.05,0.1,或0.2 mg/kg/day进行生育力研究给予药物对交配行为或妊娠能力没有影响。在0.2 mg/kg/day剂量时植入前丢失增加和在剂量≥ 0.1 mg/kg/day (根据Cmax约人临床暴露的0.02-0.06倍)时胚胎早期吸收增加。在多疗程研究中按临床上推荐给药方案,在5 mg/kg剂量水平(约癌症患者推荐人剂量AUC)观察到子宫萎缩;在剂量 ≥ 1 mg/kg (在人临床推荐剂量时AUC约0.2倍)黄体坏死。
在剂量0.05,0.1,或0.2 mg/kg/day时Cabazitaxel不影响受处理雄性大鼠交配行为或生育力。但是,在多疗程研究中按临床上推荐给药方案,静脉用cabazitaxel剂量1 mg/kg(癌症患者推荐人用剂量时AUC的约0.2-0.35倍)时处理在大鼠中观察到贮精囊退行性变和睾丸中精细管萎缩和在犬中用剂量0.5 mg/kg (根据AUC为癌症患者推荐人剂量约AUC的1/10)观察到最小睾丸退行性变(附睾中最小上皮单细胞坏死)。
14 临床研究
在一项随机化,开放,国际,多中心研究中在激素难治转移前列腺癌既往用含多西紫杉醇治疗方案治疗过患者评价JEVTANA与泼尼松联用的疗效和安全性。
总共755例患者被随机化接受或静脉JEVTANA 25 mg/m2每3周共最大10个疗程与泼尼松10 mg口服每天 (n=378),或接受静脉米托蒽醌[米托蒽醌]12 mg/m2每3周共10疗程与泼尼松10 mg口服每天(n=377) 共最大10个疗程。
这项研究包括超过18岁用激素难治转移前列腺癌或用RECIST评判标准可测量或不-可测量疾病有PSA水平升高或出现新病变,和ECOG(Eastern Cooperative Oncology Group)体能状态0-2患者。患者有中性粒细胞 >1,500细胞/mm3,血小板 > 100,000细胞/mm3,血红蛋白> 10 g/dL,肌酐 < 1.5 × 正常上限(ULN),总胆红素< 1× ULN,AST < 1.5 × ULN,和ALT < 1.5 × ULN。本研究排除最近6个月内充血性心衰,或心肌梗死史患者,或有不能控制心律失常,心绞痛,和/或高血压患者。
治疗组间人口统计学,包括年龄,种族,和ECOG体能状态(0-2)被平衡。在JEVTANA组中的中位年龄为68岁(范围46-92)和所有组种族分析为83.9%高加索人,6.9%亚洲,5.3%黑人和4%其它。
表3和图1中总结了对JEVTANA组相比对照组的疗效结果。。
Jevtana
Generic Name: cabazitaxel
Dosage Form: injection, solution
WARNING: NEUTROPENIA AND HYPERSENSITIVITY
Neutropenia: Neutropenic deaths have been reported. Monitor for neutropenia with frequent blood cell counts. Jevtana is contraindicated in patients with neutrophil counts of ≤1,500 cells/mm3. Primary prophylaxis with G-CSF is recommended in patients with high-risk clinical features [see Contraindications (4) and Warnings and Precautions (5.1, 5.2)].
Severe hypersensitivity: Severe hypersensitivity reactions can occur and may include generalized rash/erythema, hypotension and bronchospasm. Severe hypersensitivity reactions require immediate discontinuation of the Jevtana infusion and administration of appropriate therapy. Patients should receive premedication. Jevtana is contraindicated in patients who have a history of severe hypersensitivity reactions to cabazitaxel or to other drugs formulated with polysorbate 80 [see Dosage and Administration (2.1), Contraindications (4), and Warnings and Precautions (5.3)].
Indications and Usage for Jevtana
Jevtana® is indicated in combination with prednisone for the treatment of patients with metastatic castration-resistant prostate cancer previously treated with a docetaxel-containing treatment regimen.
Jevtana Dosage and Administration
Dosing Information
The recommended dose of Jevtana is based on calculation of the Body Surface Area (BSA), and is 20 mg/m2administered as a one-hour intravenous infusion every three weeks in combination with oral prednisone 10 mg administered daily throughout Jevtana treatment.
A dose of 25 mg/m2 can be used in select patients at the discretion of the treating healthcare provider [see Warnings and Precautions (5.1, 5.2,), Adverse Reactions (6.1), and Clinical Studies (14)].
Premedicate at least 30 minutes prior to each dose of Jevtana with the following intravenous medications to reduce the risk and/or severity of hypersensitivity [see Warnings and Precautions (5.3)]:

Patients at a 25 mg/m2 dose who require dose reduction should decrease dosage of Jevtana to 20 mg/m2. One additional dose reduction to 15 mg/m2 may be considered [see Adverse Reactions (6.1)].
Dose Modifications for Hepatic Impairment
Mild hepatic impairment (total bilirubin >1 to ≤1.5 × Upper Limit of Normal (ULN) or AST >1.5 × ULN): Administer Jevtana at a dose of 20 mg/m2.
Moderate hepatic impairment (total bilirubin >1.5 to ≤3 × ULN and AST = any): Administer Jevtana at a dose of 15 mg/m2 based on tolerability data in these patients; however, the efficacy of this dose is unknown.
Severe hepatic impairment (total bilirubin >3 × ULN): Jevtana is contraindicated in patients with severe hepatic impairment [see Warning and Precautions (5.7) and Clinical Pharmacology (12.3)].
Dose Modifications for Use with Strong CYP3A Inhibitors
Concomitant drugs that are strong CYP3A inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, voriconazole) may increase plasma concentrations of cabazitaxel. Avoid the coadministration of Jevtana with these drugs. If patients require coadministration of a strong CYP3A inhibitor, consider a 25% Jevtana dose reduction [see Drug Interactions (7.1) and Clinical Pharmacology (12.3)].
Preparation and Administration
Jevtana is a cytotoxic anticancer drug. Follow applicable special handling and disposal procedures [see References (15)]. If Jevtana first diluted solution, or second (final) dilution for intravenous infusion should come into contact with the skin or mucous, immediately and thoroughly wash with soap and water.
Do not use PVC infusion containers or polyurethane infusions sets for preparation and administration of Jevtana infusion solution.
Jevtana should not be mixed with any other drugs.
Preparation
Read this entire section carefully before mixing and diluting. Jevtana requires two dilutions prior to administration. Follow the preparation instructions provided below, as improper preparation may lead to overdose [see Overdosage (10)].
Note: Both the Jevtana injection and the diluent vials contain an overfill to compensate for liquid loss during preparation. This overfill ensures that after dilution with the entire contents of the accompanying diluent, there is an initial diluted solution containing 10 mg/mL Jevtana.
Inspect the Jevtana injection and supplied diluent vials. The Jevtana injection is a clear yellow to brownish-yellow viscous solution.
Step 1 – First Dilution
Each vial of Jevtana (cabazitaxel) 60 mg/1.5 mL must first be mixed with the entire contents of supplied diluent. Once reconstituted, the resultant solution contains 10 mg/mL of Jevtana.
When transferring the diluent, direct the needle onto the inside wall of Jevtana vial and inject slowly to limit foaming. Remove the syringe and needle and gently mix the initial diluted solution by repeated inversions for at least 45 seconds to assure full mixing of the drug and diluent. Do not shake.
Let the solution stand for a few minutes to allow any foam to dissipate, and check that the solution is homogeneous and contains no visible particulate matter. It is not required that all foam dissipate prior to continuing the preparation process.
The resulting initial diluted Jevtana solution (cabazitaxel 10 mg/mL) requires further dilution before administration. The second dilution should be done immediately (within 30 minutes) to obtain the final infusion as detailed in Step 2.
Step 2 – Second (Final) Dilution
Withdraw the recommended dose from the Jevtana solution containing 10 mg/mL as prepared in Step 1 using a calibrated syringe and further dilute into a sterile 250 mL PVC-free container of either 0.9% sodium chloride solution or 5% dextrose solution for infusion. If a dose greater than 65 mg of Jevtana is required, use a larger volume of the infusion vehicle so that a concentration of 0.26 mg/mL Jevtana is not exceeded. The concentration of the Jevtana final infusion solution should be between 0.10 mg/mL and 0.26 mg/mL.
Remove the syringe and thoroughly mix the final infusion solution by gently inverting the bag or bottle.
As the final infusion solution is supersaturated, it may crystallize over time. Do not use if this occurs and discard.
Fully prepared Jevtana infusion solution (in either 0.9% sodium chloride solution or 5% dextrose solution) should be used within 8 hours at ambient temperature (including the one-hour infusion), or for a total of 24 hours (including the one-hour infusion) under the refrigerated conditions.
Discard any unused portion.
Administration
Inspect visually for particulate matter, any crystals and discoloration prior to administration. If the Jevtana first diluted solution or second (final) infusion solution is not clear or appears to have precipitation, it should be discarded.
Use an in-line filter of 0.22 micrometer nominal pore size (also referred to as 0.2 micrometer) during administration.
The final Jevtana infusion solution should be administered intravenously as a one-hour infusion at room temperature.
Dosage Forms and Strengths
Jevtana (cabazitaxel) injection is supplied as a kit consisting of the following:
Cabazitaxel injection: 60 mg/1.5 mL; a clear yellow to brownish-yellow viscous solution
Diluent: 5.7 mL of 13% (w/w) ethanol in water; a clear colorless solution
Contraindications
Jevtana is contraindicated in patients with:
neutrophil counts of ≤1,500/mm3 [see Warnings and Precautions (5.1)]
history of severe hypersensitivity reactions to cabazitaxel or to other drugs formulated with polysorbate 80 [see Warnings and Precautions (5.3)]
severe hepatic impairment (total bilirubin >3 × ULN) [see Warnings and Precautions (5.7)]
pregnancy (Jevtana can cause fetal harm and potential loss of pregnancy) [see Use in Specific Populations (8.1)
]Warnings and Precautions
Bone Marrow Suppression
Jevtana is contraindicated in patients with neutrophils ≤1,500/mm3 [see Contraindications (4)]. Closely monitor patients with hemoglobin <10 g/dL.
Bone marrow suppression manifested as neutropenia, anemia, thrombocytopenia and/or pancytopenia may occur. Neutropenic deaths have been reported.
In a randomized trial (TROPIC) in previously treated patients with metastatic castration-resistant prostate cancer, five patients (1.3%) died from infection (sepsis or septic shock). All had grade 4 neutropenia and one had febrile neutropenia. One additional patient's death was attributed to neutropenia without a documented infection. Twenty-two (6%) patients discontinued Jevtana treatment due to neutropenia, febrile neutropenia, infection, or sepsis. The most common adverse reaction leading to treatment discontinuation in the Jevtana group was neutropenia (2%). Grade 3–4 neutropenia has been observed in 82% of patients treated with Jevtana in the randomized trial.
In a randomized trial (PROSELICA) comparing two doses of Jevtana in previously treated metastatic castration-resistant prostate cancer, 8 patients (1%) on the 20 mg/m2 arm and 15 patients (3%) on the 25 mg/m2 arm died from infection; of these, 4 deaths on the 20 mg/m2 arm and 8 deaths on the 25 mg/m2 arm occurred within the first 30 days of treatment.
Fewer patients receiving Jevtana 20 mg/m2 were reported to have infectious adverse reactions. Grade 1–4 infections were experienced by 160 patients (28%) on the 20 mg/m2 arm and 227 patients (38%) on the 25 mg/m2 arm. Grade 3–4 infections were experienced by 57 patients (10%) on the 20 mg/m2 arm and 120 patients (20%) on the 25 mg/m2 arm. Noninferiority for overall survival was demonstrated between these two arms [see Clinical Studies (14)].
Based on guidelines for the use of G-CSF and the adverse reactions profile of Jevtana, primary prophylaxis with G-CSF is recommended in patients with high-risk clinical features (older patients, poor performance status, previous episodes of febrile neutropenia, extensive prior radiation ports, poor nutritional status, or other serious comorbidities) that predispose them to increased complications from prolonged neutropenia. The effectiveness of primary prophylaxis with G-CSF in patients receiving Jevtana has not been studied. Therapeutic use of G-CSF and secondary prophylaxis should be considered in all patients at increased risk for neutropenia complications.
Monitoring of complete blood counts is essential on a weekly basis during cycle 1 and before each treatment cycle thereafter so that the dose can be adjusted, if needed [see Dosage and Administration (2.2)].
Increased Toxicities in Elderly Patients
In a randomized trial (TROPIC), 2% of patients (3/131) <65 years of age and 6% (15/240) ≥65 years of age died of causes other than disease progression within 30 days of the last Jevtana dose. Patients ≥65 years of age are more likely to experience certain adverse reactions, including neutropenia and febrile neutropenia. The incidence of the following grade 3–4 adverse reactions were higher in patients ≥65 years of age compared to younger patients; neutropenia (87% vs 74%), and febrile neutropenia (8% vs 6%).
In a randomized clinical trial (PROSELICA) comparing two doses of Jevtana, deaths due to infection within 30 days of starting Jevtana occurred in 0.7% (4/580) patients on the 20 mg/m2 arm and 1.3% (8/595) patients on the 25 mg/m2 arm; all of these patients were >60 years of age
In PROSELICA, on the 20 mg/m2 arm, 3% (5/178) of patients <65 years of age and 2% (9/402) ≥65 years of age died of causes other than disease progression within 30 days of the last Jevtana dose. On the 25 mg/m2 arm, 2% (3/175) patients <65 years of age and 5% (20/420) ≥65 years of age died of causes other than disease progression within 30 days of the last Jevtana dose [see Adverse Reactions (6) and Use in Specific Populations (8.5)].
Hypersensitivity Reactions
Hypersensitivity reactions may occur within a few minutes following the initiation of the infusion of Jevtana, thus facilities and equipment for the treatment of hypotension and bronchospasm should be available. Severe hypersensitivity reactions can occur and may include generalized rash/erythema, hypotension and bronchospasm.
Premedicate all patients prior to the initiation of the infusion of Jevtana [see Dosage and Administration (2.1)]. Observe patients closely for hypersensitivity reactions, especially during the first and second infusions. Severe hypersensitivity reactions require immediate discontinuation of the Jevtana infusion and appropriate therapy. Jevtana is contraindicated in patients with a history of severe hypersensitivity reactions to cabazitaxel or to other drugs formulated with polysorbate 80 [see Contraindications (4)].
Gastrointestinal Adverse Reactions
Nausea, vomiting and severe diarrhea, at times, may occur. Deaths related to diarrhea and electrolyte imbalance occurred in the randomized clinical trials. Intensive measures may be required for severe diarrhea and electrolyte imbalance. Antiemetic prophylaxis is recommended. Treat patients with rehydration, antidiarrheal or antiemetic medications as needed. Treatment delay or dosage reduction may be necessary if patients experience Grade ≥3 diarrhea [see Dosage and Administration (2.2)].
Gastrointestinal (GI) hemorrhage and perforation, ileus, enterocolitis, neutropenic enterocolitis, including fatal outcome, have been reported in patients treated with Jevtana [see Adverse Reactions (6.2)]. Risk may be increased with neutropenia, age, steroid use, concomitant use of NSAIDs, antiplatelet therapy or anticoagulants, and patients with a prior history of pelvic radiotherapy, adhesions, ulceration and GI bleeding.
Abdominal pain and tenderness, fever, persistent constipation, diarrhea, with or without neutropenia, may be early manifestations of serious gastrointestinal toxicity and should be evaluated and treated promptly. Jevtana treatment delay or discontinuation may be necessary.
Renal Failure
In the randomized clinical trial (TROPIC), renal failure of any grade occurred in 4% of the patients being treated with Jevtana, including four cases with fatal outcome. Most cases occurred in association with sepsis, dehydration, or obstructive uropathy [see Adverse Reactions (6.1)]. Some deaths due to renal failure did not have a clear etiology. Appropriate measures should be taken to identify causes of renal failure and treat aggressively.
Respiratory Disorders
Interstitial pneumonia/pneumonitis, interstitial lung disease and acute respiratory distress syndrome have been reported and may be associated with fatal outcome [see Adverse Reactions (6.2)]. Patients with underlying lung disease may be at higher risk for these events. Acute respiratory distress syndrome may occur in the setting of infection.
Interrupt Jevtana if new or worsening pulmonary symptoms develop. Closely monitor, promptly investigate, and appropriately treat patients receiving Jevtana. Consider discontinuation. The benefit of resuming Jevtana treatment must be carefully evaluated.
Use in Patients with Hepatic Impairment
Cabazitaxel is extensively metabolized in the liver.
Jevtana is contraindicated in patients with severe hepatic impairment (total bilirubin >3 × ULN) [see Contraindications (4)]. Dose should be reduced for patients with mild (total bilirubin >1 to ≤1.5 × ULN or AST >1.5 × ULN) and moderate (total bilirubin >1.5 to ≤3.0 × ULN and any AST) hepatic impairment, based on tolerability data in these patients [see Dosage and Administration (2.3) and Use in Specific Populations (8.7)]. Administration of Jevtana to patients with mild and moderate hepatic impairment should be undertaken with caution and close monitoring of safety.
Adverse Reactions
The following serious adverse reactions are discussed in greater detail in another section of the label:
Bone Marrow Suppression [see Warnings and Precautions (5.1)]Use in Elderly Patients [see Warnings and Precautions (5.2)]Hypersensitivity Reactions [see Warnings and Precautions (5.3)]Gastrointestinal Adverse Reactions [see Warnings and Precautions (5.4)]Renal Failure [see Warnings and Precautions (5.5)]Respiratory Disorders [see Warnings and Precautions (5.6)]Use in Patients with Hepatic Impairment [see Warnings and Precautions (5.7)]Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, the adverse reaction rates observed cannot be directly compared to rates in other trials and may not reflect the rates observed in clinical practice.
TROPIC Trial (Jevtana + prednisone compared to mitoxantrone)
The safety of Jevtana in combination with prednisone was evaluated in 371 patients with metastatic castration-resistant prostate cancer treated in the randomized TROPIC trial, compared to mitoxantrone plus prednisone.
Deaths due to causes other than disease progression within 30 days of last study drug dose were reported in 18 (5%) Jevtana-treated patients and 3 (<1%) mitoxantrone-treated patients. The most common fatal adverse reactions in Jevtana-treated patients were infections (n=5) and renal failure (n=4). The majority (4 of 5 patients) of fatal infection-related adverse reactions occurred after a single dose of Jevtana. Other fatal adverse reactions in Jevtana-treated patients included ventricular fibrillation, cerebral hemorrhage, and dyspnea.
The most common (≥10%) grade 1–4 adverse reactions were anemia, leukopenia, neutropenia, thrombocytopenia, diarrhea, fatigue, nausea, vomiting, constipation, asthenia, abdominal pain, hematuria, back pain, anorexia, peripheral neuropathy, pyrexia, dyspnea, dysgeusia, cough, arthralgia, and alopecia.
The most common (≥5%) grade 3–4 adverse reactions in patients who received Jevtana were neutropenia, leukopenia, anemia, febrile neutropenia, diarrhea, fatigue, and asthenia.
Treatment discontinuations due to adverse drug reactions occurred in 18% of patients who received Jevtana and 8% of patients who received mitoxantrone. The most common adverse reactions leading to treatment discontinuation in the Jevtana group were neutropenia and renal failure. Dose reductions were reported in 12% of Jevtana-treated patients and 4% of mitoxantrone-treated patients. Dose delays were reported in 28% of Jevtana-treated patients and 15% of mitoxantrone-treated patients.

PROSELICA Trial (comparison of two doses of Jevtana)
In a noninferiority, multicenter, randomized, open-label study (PROSELICA), 1175 patients with metastatic castration-resistant prostate cancer, previously treated with a docetaxel-containing regimen, were treated with either Jevtana 25 mg/m2 (n=595) or the 20 mg/m2 (n=580) dose.
Deaths within 30 days of last study drug dose were reported in 22 (3.8%) patients in the 20 mg/m2 and 32 (5.4%) patients in the 25 mg/m2 arm. The most common fatal adverse reactions in Jevtana-treated patients were related to infections, and these occurred more commonly on the 25 mg/m2 arm (n=15) than on the 20 mg/m2 arm (n=8). Other fatal adverse reactions in Jevtana-treated patients included cerebral hemorrhage, respiratory failure, paralytic ileus, diarrhea, acute pulmonary edema, disseminated intravascular coagulation, renal failure, sudden death, cardiac arrest, ischemic stroke, diverticular perforation, and cardiorenal syndrome.
Grade 1–4 adverse reactions occurring ≥5% more commonly in patients on the 25 mg/m2 versus 20 mg/m2 arms were leukopenia, neutropenia, thrombocytopenia, febrile neutropenia, decreased appetite, nausea, diarrhea, asthenia, and hematuria.
Grade 3–4 adverse reactions occurring ≥5% more commonly in patients on the 25 mg/m2 versus 20 mg/m2 arms were leukopenia, neutropenia, and febrile neutropenia.
Treatment discontinuations due to adverse drug reactions occurred in 17% of patients in the 20 mg/m2group and 20% of patients in the 25 mg/m2 group. The most common adverse reactions leading to treatment discontinuation were fatigue and hematuria. The patients in the 20 mg/m2 group received a median of 6 cycles (median duration of 18 weeks), while patients in the 25 mg/m2 group received a median of 7 cycles (median duration of 21 weeks). In the 25 mg/m2 group, 128 patients (22%) had a dose reduced from 25 to 20 mg/m2, 19 patients (3%) had a dose reduced from 20 to 15 mg/m2 and 1 patient (0.2%) had a dose reduced from 15 to 12 mg/m2. In the 20 mg/m2 group, 58 patients (10%) had a dose reduced from 20 to 15 mg/m2, and 9 patients (2%) had a dose reduced from 15 to 12 mg/m2.

Hematuria
In study TROPIC, adverse reactions of hematuria, including those requiring medical intervention, were more common in Jevtana-treated patients. The incidence of grade ≥2 hematuria was 6% in Jevtana-treated patients and 2% in mitoxantrone-treated patients. Other factors associated with hematuria were well-balanced between arms and do not account for the increased rate of hematuria on the Jevtana arm.
In study PROSELICA, hematuria of all grades was observed in 18% of patients overall.
Hepatic Laboratory Abnormalities
The incidences of grade 3–4 increased AST, increased ALT, and increased bilirubin were each ≤1%.
Postmarketing Experience
The following adverse reactions have been identified from clinical trials and/or postmarketing surveillance. Because they are reported from a population of unknown size, precise estimates of frequency cannot be made.
Gastrointestinal: Gastritis, intestinal obstruction.
Respiratory: Interstitial pneumonia/pneumonitis, interstitial lung disease and acute respiratory distress syndrome.
Drug InteractionsCYP3A Inhibitors
Cabazitaxel is primarily metabolized through CYP3A [see Clinical Pharmacology (12.3)]. Strong CYP3A inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, voriconazole) may increase plasma concentrations of cabazitaxel. Avoid the coadministration of Jevtana with strong CYP3A inhibitors. If patients require coadministration of a strong CYP3A inhibitor, consider a 25% Jevtana dose reduction [see Dosage and Administration (2.4) and Clinical Pharmacology (12.3)].
USE IN SPECIFIC POPULATIONSPregnancy
Risk Summary
Jevtana is contraindicated for use in pregnant women because the drug can cause fetal harm and potential loss of pregnancy. Jevtana is not indicated for use in female patients. There are no human data on the use of cabazitaxel injection in pregnant women. In animal reproduction studies, intravenous administration of cabazitaxel in pregnant rats during organogenesis caused embryonic and fetal death at doses lower than the maximum recommended human dose [see Data].
Data
Animal Data
In an early embryonic developmental toxicity study in rats, cabazitaxel was administered intravenously for 15 days prior to mating through Day 6 of pregnancy, which resulted in an increase in pre-implantation loss at 0.2 mg/kg/day and an increase in early resorptions at ≥0.1 mg/kg/day (approximately 0.06 and 0.02 times the Cmax in patients at the recommended human dose, respectively).
In an embryo-fetal developmental toxicity study in rats, cabazitaxel caused maternal and embryofetal toxicity consisting of increased postimplantation loss, embryolethality, and fetal deaths when administered intravenously at a dose of 0.16 mg/kg/day (approximately 0.06 times the Cmax in patients at the recommended human dose). Decreased mean fetal birthweight associated with delays in skeletal ossification was observed at doses ≥0.08 mg/kg. Cabazitaxel crossed the placenta barrier within 24 hours of a single intravenous administration of 0.08 mg/kg to pregnant rats at gestational day 17. A dose of 0.08 mg/kg in rats resulted in a Cmax approximately 0.02 times that observed in patients at the recommended human dose. Administration of cabazitaxel did not result in fetal abnormalities in rats or rabbits at exposure levels significantly lower than the expected human exposures.
Lactation
Risk Summary
Jevtana is not indicated for use in female patients. There is no information available on the presence of cabazitaxel in human milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production. Cabazitaxel or cabazitaxel metabolites are excreted in maternal milk of lactating rats [see Data].
Data
Animal Data
In a milk excretion study, radioactivity related to cabazitaxel was detected in the stomachs of nursing pups within 2 hours of a single intravenous administration of cabazitaxel to lactating rats at a dose of 0.08 mg/kg (approximately 0.02 times the Cmax in patients at the recommended human dose). This was detectable 24 hours post dose. Approximately 1.5% of the dose delivered to the mother was calculated to be delivered in the maternal milk.
Females and Males of Reproductive Potential
Contraception
Males
Based on findings in animal reproduction studies, advise male patients with female partners of reproductive potential to use effective contraception during treatment and for 3 months after the final dose of Jevtana [see Use in Specific Populations (8.1)].
Infertility

Based on animal toxicology studies, cabazitaxel injection may impair human fertility in males of reproductive potential [see Nonclinical Toxicology (13.1)].
Pediatric Use
The safety and effectiveness of Jevtana in pediatric patients have not been established.
Jevtana was evaluated in 39 pediatric patients (ages 3 to 18 years) receiving prophylactic G-CSF. The maximum tolerated dose (MTD) was 30 mg/m2 intravenously over 1 hour on Day 1 of a 21 day cycle in pediatric patients with solid tumors based on the dose-limiting toxicity (DLT) of febrile neutropenia. No objective responses were observed in 11 patients with refractory high grade glioma (HGG) or diffuse intrinsic pontine glioma (DIPG). One patient had a partial response among the 9 patients with ependymoma.
Infusion related/hypersensitivity reactions were seen in 10 patients (26%). Three patients experienced serious adverse events of anaphylactic reaction. The incidence of infusion related/hypersensitivity reactions decreased with steroid pre-medication. The most frequent treatment-emergent adverse events were similar to those reported in adults.
Based on the population pharmacokinetics analysis conducted with data from 31 pediatric patients with cancer (ages 3 to 18 years), the clearances by body surface area were comparable to those in adults.
Geriatric Use
In the TROPIC study, of the 371 patients with prostate cancer treated with Jevtana every three weeks plus prednisone, 240 patients (64.7%) were 65 years of age and over, while 70 patients (18.9%) were 75 years of age and over. No overall differences in effectiveness were observed between patients ≥65 years of age and younger patients. Elderly patients (≥65 years of age) may be more likely to experience certain adverse reactions. The incidence of death due to causes other than disease progression within 30 days of the last cabazitaxel dose were higher in patients who were 65 years of age or greater compared to younger patients [see Warnings and Precautions (5.2)]. The incidence of grade 3–4 neutropenia and febrile neutropenia were higher in patients who were 65 years of age or greater compared to younger patients. The following grade 1–4 adverse reactions were reported at rates ≥5% higher in patients 65 years of age or older compared to younger patients: fatigue (40% vs 30%), neutropenia (97% vs 89%), asthenia (24% vs 15%), pyrexia (15% vs 8%), dizziness (10% vs 5%), urinary tract infection (10% vs 3%), and dehydration (7% vs 2%), respectively.
In the PROSELICA study, the grade 1–4 adverse reactions reported at rates of at least 5% higher in patients 65 years of age or older compared to younger patients were diarrhea (43% vs 33%), fatigue (30% vs 19%), asthenia (22% vs 13%), constipation (20% vs 13%), clinical neutropenia (13% vs 6%), febrile neutropenia (11% vs 5%), and dyspnea (10% vs 3%).
Based on a population pharmacokinetic analysis, no significant difference was observed in the pharmacokinetics of cabazitaxel between patients <65 years (n=100) and older (n=70).
Renal Impairment
No dose adjustment is necessary in patients with renal impairment not requiring hemodialysis. Patients presenting with end-stage renal disease (creatinine clearance CLCR <15 mL/min/1.73 m2), should be monitored carefully during treatment [see Clinical Pharmacology (12.3)].
Hepatic Impairment
Cabazitaxel is extensively metabolized in the liver. Patients with mild hepatic impairment (total bilirubin >1 to ≤1.5 × ULN or AST >1.5 × ULN) should have Jevtana dose of 20 mg/m2. Administration of cabazitaxel to patients with mild hepatic impairment should be undertaken with caution and close monitoring of safety [see Clinical Pharmacology (12.3)]. The maximum tolerated dose in patients with moderate hepatic impairment (total bilirubin >1.5 to ≤3.0 × ULN and AST = any) was 15 mg/m2, however, the efficacy at this dose level was unknown. Jevtana is contraindicated in patients with severe hepatic impairment (total bilirubin >3 × ULN) [see Contraindications (4)].
Overdosage
There is no known antidote for Jevtana overdose. Overdose has resulted from improper preparation [see Dosage and Administration (2.5)]. Read the entire section Dosage and Administration (2) carefully before mixing or diluting. Complications of overdose include exacerbation of adverse reactions such as bone marrow suppression and gastrointestinal disorders. Overdose has led to fatal outcome.
In case of overdose, the patient should be kept in a specialized unit where vital signs, chemistry and particular functions can be closely monitored. Patients should receive therapeutic G-CSF as soon as possible after discovery of overdose. Other appropriate symptomatic measures should be taken, as needed.
Jevtana Description
Jevtana (cabazitaxel) injection is an antineoplastic agent belonging to the taxane class that is for intravenous use. It is prepared by semi-synthesis with a precursor extracted from yew needles.
The chemical name of cabazitaxel is (2α,5β,7β,10β,13α)-4-acetoxy-13-({(2R,3S)-3-[(tertbutoxycarbonyl) amino]-2-hydroxy-3-phenylpropanoyl}oxy)-1-hydroxy-7,10-dimethoxy-9-oxo-5,20-epoxytax-11-en-2-yl benzoate–propan-2-one (1:1).
Cabazitaxel has the following structural formula:
Cabazitaxel is a white to almost-white powder with a molecular formula of C45H57NO14C3H6O and a molecular weight of 894.01 (for the acetone solvate) / 835.93 (for the solvent free). It is lipophilic, practically insoluble in water and soluble in alcohol.
Jevtana (cabazitaxel) injection 60 mg/1.5 mL is a sterile, non-pyrogenic, clear yellow to brownish-yellow viscous solution and is available in single-dose vials containing 60 mg cabazitaxel (anhydrous and solvent free) and 1.56 g polysorbate 80.
Each mL contains 40 mg cabazitaxel (anhydrous) and 1.04 g polysorbate 80.
DILUENT for Jevtana is a clear, colorless, sterile, and non-pyrogenic solution containing 13% (w/w) ethanol in water for injection, approximately 5.7 mL.
Jevtana requires two dilutions prior to intravenous infusion. Jevtana injection should be diluted only with the supplied DILUENT for Jevtana, followed by dilution in either 0.9% sodium chloride solution or 5% dextrose solution.
Jevtana - Clinical PharmacologyMechanism of Action
Cabazitaxel is a microtubule inhibitor. Cabazitaxel binds to tubulin and promotes its assembly into microtubules while simultaneously inhibiting disassembly. This leads to the stabilization of microtubules, which results in the inhibition of mitotic and interphase cellular functions.
Pharmacodynamics
Cardiac Electrophysiology
The effect of cabazitaxel following a single dose of 25 mg/m2 administered by intravenous infusion on QTc interval was evaluated in 94 patients with solid tumors. No large changes in the mean QT interval (i.e., >20 ms) from baseline based on Fridericia correction method were detected. However, a small increase in the mean QTc interval (i.e., <10 ms) cannot be excluded due to study design limitations.
Pharmacokinetics
A population pharmacokinetic analysis was conducted in 170 patients with solid tumors at doses ranging from 10 to 30 mg/m2 weekly or every three weeks.
Absorption
Based on the population pharmacokinetic analysis, after an intravenous dose of cabazitaxel 25 mg/m2every three weeks, the mean Cmax in patients with metastatic prostate cancer was 226 ng/mL (CV 107%) and was reached at the end of the one-hour infusion (Tmax). The mean AUC in patients with metastatic prostate cancer was 991 ng∙h/mL (CV 34%).
No major deviation from the dose proportionality was observed from 10 to 30 mg/m2 in patients with advanced solid tumors.
Distribution
The volume of distribution (Vss) was 4,864 L (2,643 L/m2 for a patient with a median BSA of 1.84 m2) at steady state.
In vitro, the binding of cabazitaxel to human serum proteins was 89 to 92% and was not saturable up to 50,000 ng/mL, which covers the maximum concentration observed in clinical trials. Cabazitaxel is mainly bound to human serum albumin (82%) and lipoproteins (88% for HDL, 70% for LDL, and 56% for VLDL). The in vitro blood-to-plasma concentration ratio in human blood ranged from 0.90 to 0.99, indicating that cabazitaxel was equally distributed between blood and plasma.
Metabolism
Cabazitaxel is extensively metabolized in the liver (>95%), mainly by the CYP3A4/5 isoenzyme (80% to 90%), and to a lesser extent by CYP2C8. Cabazitaxel is the main circulating moiety in human plasma. Seven metabolites were detected in plasma (including the 3 active metabolites issued from O-demethylation), with the main one accounting for 5% of cabazitaxel exposure. Around 20 metabolites of cabazitaxel are excreted into human urine and feces.
Elimination
After a one-hour intravenous infusion [14C]-cabazitaxel 25 mg/m2, approximately 80% of the administered dose was eliminated within 2 weeks. Cabazitaxel is mainly excreted in the feces as numerous metabolites (76% of the dose); while renal excretion of cabazitaxel and metabolites account for 3.7% of the dose (2.3% as unchanged drug in urine).
Based on the population pharmacokinetic analysis, cabazitaxel has a plasma clearance of 48.5 L/h (CV 39%; 26.4 L/h/m2 for a patient with a median BSA of 1.84 m2) in patients with metastatic prostate cancer. Following a one-hour intravenous infusion, plasma concentrations of cabazitaxel can be described by a three-compartment pharmacokinetic model with α-, β-, and γ- half-lives of 4 minutes, 2 hours, and 95 hours, respectively.
Renal Impairment
Cabazitaxel is minimally excreted via the kidney. A population pharmacokinetic analysis carried out in 170 patients including 14 patients with moderate renal impairment (30 mL/min ≤CLCR <50 mL/min) and 59 patients with mild renal impairment (50 mL/min ≤CLCR <80 mL/min) showed that mild to moderate renal impairment did not have meaningful effects on the pharmacokinetics of cabazitaxel. This was confirmed by a dedicated comparative pharmacokinetic study in patients with solid tumors with normal renal function (n=8, CLCR >80 mL/min/1.73 m2), or moderate (n=8, 30 mL/min/1.73 m2 ≤CLCR <50 mL/min/1.73 m2) and severe (n=9, CLCR <30 mL/min/1.73 m2) renal impairment, who received several cycles of cabazitaxel in single IV infusion up to 25 mg/m2. Limited pharmacokinetic data were available in patients with end-stage renal disease (n=2, CLCR <15 mL/min/1.73 m2).
Hepatic Impairment
Cabazitaxel is extensively metabolized in the liver.
A dedicated study in 43 cancer patients with hepatic impairment showed no influence of mild (total bilirubin >1 to ≤1.5 × ULN or AST >1.5 × ULN) or moderate (total bilirubin >1.5 to ≤3.0 × ULN) hepatic impairment on cabazitaxel pharmacokinetics. The maximum tolerated dose (MTD) of cabazitaxel was 20 and 15 mg/m2, respectively.
In 3 patients with severe hepatic impairment (total bilirubin >3 × ULN), a 39% decrease in clearance was observed when compared to patients with mild hepatic impairment (ratio=0.61, 90% CI: 0.36–1.05), indicating some effect of severe hepatic impairment on cabazitaxel pharmacokinetics. The MTD of cabazitaxel in patients with severe hepatic impairment was not established. Based on safety and tolerability data, cabazitaxel dose should be maintained at 20 mg/m2 in patients with mild hepatic impairment and reduced to 15 mg/m2 in patients with moderate hepatic impairment [see Warnings and Precautions (5.7) and Use in Specific Populations (8.7)]. Cabazitaxel is contraindicated in patients with severe hepatic impairment [see Contraindications (4) and Use in Specific Populations (8.7)].
Drug Interactions
A drug interaction study of Jevtana in 23 patients with advanced cancers has shown that repeated administration of ketoconazole (400 mg orally once daily), a strong CYP3A inhibitor, increased the exposure to cabazitaxel (5 mg/m2 intravenous) by 25%.
A drug interaction study of Jevtana in 13 patients with advanced cancers has shown that repeated administration of aprepitant (125 or 80 mg once daily), a moderate CYP3A inhibitor, did not modify the exposure to cabazitaxel (15 mg/m2 intravenous).
A drug interaction study of Jevtana in 21 patients with advanced cancers has shown that repeated administration of rifampin (600 mg once daily), a strong CYP3A inducer, decreased the exposure to cabazitaxel (15 mg/m2 intravenous) by 17%.
A drug interaction study of Jevtana in 11 patients with advanced cancers has shown that cabazitaxel (25 mg/m2 administered as a single 1-hour infusion) did not modify the exposure to midazolam, a probe substrate of CYP3A.
Prednisone or prednisolone administered at 10 mg daily did not affect the pharmacokinetics of cabazitaxel.
Based on in vitro studies, the potential for cabazitaxel to inhibit drugs that are substrates of other CYP isoenzymes (1A2,-2B6,-2C9, -2C8, -2C19, -2E1, -2D6, and CYP3A4/5) is low. In addition, cabazitaxel did not induce CYP isozymes (-1A, -2C9 and -3A) in vitro.
In vitro, cabazitaxel did not inhibit the multidrug-resistance protein 1 (MRP1), 2 (MRP2) or organic cation transporter (OCT1). In vitro, cabazitaxel inhibited P-gp, BRCP, and organic anion transporting polypeptides (OATP1B1, OATP1B3). However the in vivo risk of cabazitaxel inhibiting MRPs, OCT1, P-gp, BCRP, OATP1B1 or OATP1B3 is low at the dose of 25 mg/m2.
In vitro, cabazitaxel is a substrate of P-gp, but not a substrate of MRP1, MRP2, BCRP, OCT1, OATP1B1 or OATP1B3.
Nonclinical ToxicologyCarcinogenesis, Mutagenesis, Impairment of Fertility
Long-term animal studies have not been performed to evaluate the carcinogenic potential of cabazitaxel.
Cabazitaxel was positive for clastogenesis in the in vivo micronucleus test, inducing an increase of micronuclei in rats at doses ≥0.5 mg/kg. Cabazitaxel increased numerical aberrations with or without metabolic activation in an in vitro test in human lymphocytes though no induction of structural aberrations was observed. Cabazitaxel did not induce mutations in the bacterial reverse mutation (Ames) test. The positive in vivo genotoxicity findings are consistent with the pharmacological activity of the compound (inhibition of tubulin depolymerization).
In a fertility study performed in female rats at cabazitaxel doses of 0.05, 0.1, or 0.2 mg/kg/day there was no effect of administration of the drug on mating behavior or the ability to become pregnant. In repeat-dose toxicology studies in rats with intravenous cabazitaxel administration once every three weeks for up to 6 months, atrophy of the uterus was observed at the 5 mg/kg dose level (approximately the AUC in patients with cancer at the recommended human dose) along with necrosis of the corpora lutea at doses ≥1 mg/kg (approximately 0.2 times the AUC at the clinically recommended human dose).
In a fertility study in male rats, cabazitaxel did not affect mating performances or fertility at doses of 0.05, 0.1, or 0.2 mg/kg/day. In repeat-dose toxicology studies with intravenous cabazitaxel administration once every three weeks for up to 9 months, degeneration of seminal vesicle and seminiferous tubule atrophy in the testis were observed in rats at a dose of 1 mg/kg (approximately 0.2 times the AUC in patients at the recommended human dose), and minimal testicular degeneration (minimal epithelial single cell necrosis in epididymis) was observed in dogs treated at a dose of 0.5 mg/kg (approximately 0.1 times the AUC in patients at the recommended human dose).
Clinical StudiesTROPIC Trial (Jevtana + prednisone compared to mitoxantrone)
The efficacy and safety of Jevtana in combination with prednisone were evaluated in a randomized, open-label, international, multi-center study in patients with metastatic castration-resistant prostate cancer previously treated with a docetaxel-containing treatment regimen (TROPIC, NCT00417079).
A total of 755 patients were randomized to receive either Jevtana 25 mg/m2 intravenously every 3 weeks for a maximum of 10 cycles with prednisone 10 mg orally daily (n=378), or to receive mitoxantrone 12 mg/m2 intravenously every 3 weeks for 10 cycles with prednisone 10 mg orally daily (n=377) for a maximum of 10 cycles.
This study included patients over 18 years of age with hormone-refractory metastatic prostate cancer either measurable by RECIST criteria or non-measurable disease with rising PSA levels or appearance of new lesions, and ECOG (Eastern Cooperative Oncology Group) performance status 0–2. Patients had to have neutrophils >1,500 cells/mm3, platelets >100,000 cells/mm3, hemoglobin >10 g/dL, creatinine <1.5 × upper limit of normal (ULN), total bilirubin <1 × ULN, AST <1.5 × ULN, and ALT <1.5 × ULN. Patients with a history of congestive heart failure, or myocardial infarction within the last 6 months, or patients with uncontrolled cardiac arrhythmias, angina pectoris, and/or hypertension were not included in the study.
Demographics, including age, race, and ECOG performance status (0–2) were balanced between the treatment arms. The median age was 68 years (range 46–92) and the racial distribution for all groups was 83.9% Caucasian, 6.9% Asian, 5.3% Black, and 4% Others in the Jevtana group.
Efficacy results for the Jevtana arm versus the control arm are summarized in Table 5 and Figure 1.

PROSELICA Trial (comparison of two doses of Jevtana)
In a noninferiority, multicenter, randomized, open-label study (PROSELICA, NCT01308580), 1200 patients with metastatic castration-resistant prostate cancer, previously treated with a docetaxel-containing regimen, were randomized to receive either Jevtana 25 mg/m2 (n=602) or 20 mg/m2(n=598) dose. Overall survival (OS) was the major efficacy outcome.
Demographics, including age, race, and ECOG performance status (0–2) were balanced between the treatment arms. The median age was 68 years (range 45–89) and the racial distribution for all groups was 87% Caucasian, 6.9% Asian, 2.3% Black, and 3.8% Others in the Jevtana 20 mg/m2 group. The median age was 69 years (range 45–88) and the racial distribution for all groups was 88.7% Caucasian, 6.6% Asian, 1.8% Black, and 2.8% Others in the Jevtana 25 mg/m2 group.
The study demonstrated noninferiority in overall survival (OS) of Jevtana 20 mg/m2 in comparison with Jevtana 25 mg/m2 in an intent-to-treat population (see Table 6 and Figure 2). Based on the per-protocol population, the estimated median OS was 15.1 months on Jevtana 20 mg/m2 and 15.9 months on Jevtana 25 mg/m2, the observed hazard ratio (HR) of OS was 1.042 (97.78% CI: 0.886, 1.224). Among the subgroup analyses intended for assessing the heterogeneity, no notable difference in OS was observed on the Jevtana 25 mg/m2 arm compared to the Jevtana 20 mg/m2 arm in subgroups based on the stratification factors of ECOG performance status score, measurability of disease, or region.
