5 警告和注意事项
5.1 骨髓抑制
在用SYNRIBO无对照试验,有慢性期和加速期CML患者分别经受NCI CTC(版本3.0)3或4级血小板减少(85%,88%),中性粒细胞减低(81%,71%),和贫血(62%,80%)。在安全性人群(N=163)中3%患者发生骨髓抑制相关死亡。中性粒细胞减低患者是处在感染风险增加,和应频繁监视和如有感染或发热症状劝告联系医生。
在诱导和初始维持疗程和维持疗程后期当临床上指示时每周监视完全血细胞计数。在临床试验中骨髓抑制一般是可逆的和通常用延后下一疗程处理疗程和/或减少用SYNRIBO治疗天数[见剂型和给药方法(2.3)和不良反应(6.1)]
5.2 出血
SYNRIBO引起严重血小板减少增加出血风险。在临床试验中有CP和AP CML患者,观察到3和4级血小板减少发生率高(分别85%和88%)。在安全性人群中用SYNRIBO治疗患者2%发生来自脑出血死亡。在安全性人群2%患者发生严重,非致命性,胃肠道出血。大多数出血事件伴随严重血小板减少。
建议监视血小板计数作为全血细胞CBC监视的一部分[见警告和注意事项(5.1)]。当血小板计数低于50,000/μL避免抗凝剂,阿司匹林,和非甾体抗炎药(NSAIDs)因可能增加出血风险。
5.3 高血糖
SYNRIBO可能诱发葡萄糖不能耐受。在安全性人群中11%患者报道3或4级高血糖。在安全性人群中用SYNRIBO治疗患者发生1例高渗性非酮性高血糖。频繁监视血葡萄糖水平,尤其是糖尿病或糖尿病风险因子患者。避免在糖尿病控制不佳患者使用SYNRIBO直至确定已良好控制血糖。
5.4 胚胎胎儿毒性
当SYNRIBO给予妊娠妇女可能致胎儿危害。在动物中Omacetaxine mepesuccinate引起胚胎-胎儿死亡。有生育能力妇女当正在用SYNRIBO时应避免成为妊娠。在妊娠妇女中没有SYNRIBO的适当和对照良好研究。如此药在妊娠期间使用,或当接受此药时患者成为妊娠,应忠告患者对胎儿潜在危害[见在特殊人群中使用(8.1)]。
6 不良反应
在临床试验中伴随SYNRIBO以下严重不良反应和在说明书的其他节中更详细探讨:
● 骨髓抑制[见警告和注意事项(5.1)]
● 出血[见警告和注意事项(5.2)]
● 高血糖[见警告和注意事项(5.3)]
因为临床试验是在广泛不同情况下进行的,临床试验观察到不良反应率不能与另一种药临床试验发生率直接比较而且可能不反映实践中观察到的发生率。
从3项临床试验得到对SYNRIBO的安全性数据,其中总共纳入163例酪氨酸酶抑制TKI 耐药和/或不能耐受的慢性期(N=108)和加速期(N=55)CML成年患者。所有患者用初始诱导治疗,包括剂量1.25 mg/m2皮下给药每天2次每28天共连续14天(诱导疗程)。然后有反应患者用相同剂量治疗和一个每天2次方案每28天共连续7天(维持疗程)。
6.1 临床试验经验
慢性期CML
108例慢性期CML患者中位暴露时间为7.4个月(范围0至43个月)。暴露的中位总疗程为6个月(范围1至41),和试验期间输送中位总剂量为131 mg/m2(范围1.2至678)。慢性期CML患者中,治疗疗程1期间87%接受14天。疗程2和3,接受14天治疗患者的百分率分别减低至42%和16%。其中91例患者至少接受2个疗程治疗,试验期间79例(87%)至少延迟1个疗程。当更多患者接受诱导疗程最长的疗程延迟中位天数对疗程2(17天)和疗程3(25天)。
99%的慢性期CML患者报道不良反应。总共18%患者因不良反应导致撤药。导致终止最频发生不良反应为全细胞减少,血小板减少,和丙氨酸转移酶增加(各2%)。总共87%患者至少报道1次 3级或4级治疗出现不良反应(表1)。
对51%患者报道严重不良反应。报道的严重不良反应至少5%患者是骨髓衰竭和血小板减少(各10%),和发热性中性粒细胞减低(6%)。8%患者报道感染严重不良反应。
在5例(5%)CP CML患者研究时发生死亡。两例患者死于脑出血,1例由于多器官衰竭,1例由于疾病的进展,和1例原因不明。
加速期CML
暴露的中位总疗程为2(范围1至29),和试验期间输送中位总剂量为70 mg/m2。中位暴露时间对55例加速期CML患者为1.9个月(范围0至30个月)。其中加速期CML患者,疗程1期间86%接受14天治疗。疗程2和3,接受14天治疗患者的百分率分别减低至55%和44%。其中40例患者至少接受2个疗程治疗,延迟试验期间27例(68%)至少1个疗程。延迟疗程最大中位天数对疗程3(31天)和疗程8(36天)。
无论研究者归属对加速期CML患者报道不良反应100%。总共33%患者有不良反应导致撤药。导致撤药最频发生不良反应是白细胞增多(6%),和血小板减少(4%). 总共84%患者报道至少1次3级或4级治疗出现的不良反应(表2)。
60%患者报道严重不良反应。报道的严重不良反应至少5%患者是发热性中性粒细胞减低(18%),血小板减少(9%),贫血(7%),腹泻和抽搐(各6%)。对11%患者报道的严重不良反应是感染。在研究中5例(9%) AP CML患者发生死亡。两例患者死于脑出血和3例由于疾病进展。
在慢性和加速期CML实验室异常
表3中描述在有慢性和加速期CML患者中报道的3/4级实验室异常。所有用SYNRIBO治疗患者发生骨髓抑制[见警告和注意事项(5.1)]。5例慢性期CML和4患者加速期CML患者由于全细胞减少,血小板减少,发热性中性粒细胞减低,或骨髓坏死永远终止SYNRIBO。在安全性人群报道1例高渗性非酮性高血糖事件和在文献中报道1相似病例。两例慢性期CML患者由于转氨酶升高永远终止SYNRIBO。

7 药物相互作用
根据来自体外用SYNRIBO药物相互作用研究发现,无必要临床临床药物相互作用试验。[见临床药理学(12.3)]
8 特殊人群中使用
8.1 妊娠
妊娠类别D[见警告和注意事项(5.4)]
根据其作用机制和来自动物研究发现,当给予妊娠妇女SYNRIBO可能致胎儿危害。如妊娠期间使用本药,或如服用此药时患者成为妊娠,应忠告患者对胎儿潜在危害。
在一项胚胎-胎儿发育研究,在器官形成期时妊娠小鼠被皮下给予omacetaxine mepesuccinate剂量0.21或0.41 mg/kg/day。药物-相关不良作用包括胚胎死亡,未骨化骨/减低骨化增加和减低胎儿体重。胎儿毒性发生在剂量0.41 mg/kg(1.23 mg/m2)按照体表面积为人每天推荐剂量的约一半。
8.3 哺乳母亲
不知道omacetaxine mepesuccinate是否排泄在人乳汁中。因为许多药物排泄在乳汁和因为哺乳婴儿严重不良反应的潜能,应做出决策是否继续哺乳或终止药物,考虑药物对母亲的重要性。
8.4 儿童使用
未确定SYNRIBO在儿童患者中安全性和有效性。
8.5 老年人使用
在慢性和加速期CML中疗效人群中23(30%)和16(46%)患者是 ≥65岁。对<65岁和≥65岁年龄亚组,亚组间有差异,较轻CP CML患者与较老患者比较主要细胞遗传学反应(MCyRs)有较高率(分别23%相比9%)和较老AP CML患者d与较年轻患者比较主要血液学反应(MaHRs)有较高率(分别31%相比0%)。≥65岁患者更可能经受毒性,最显著为血液学毒性。
8.6 肾受损
未进行正式研究评估肾受损对omacetaxine mepesuccinate的药代动力学的影响。
8.7 肝受损
未进行正式研究评估肝受损对omacetaxine mepesuccinate的药代动力学的影响。
8.8 性别的效应
在慢性期CML人群疗效分析包括76例患者,其中47例(62%)患者为男性和29例(38%)为女性。对慢性期CML患者,男性MCyR率高于妇女(分别21%相比14%)。注意到在男性和妇女慢性期CML中omacetaxine mepesuccinate的安全性图形有差别。虽然各组患者数量小阻止确定性评估。在加速期亚组患者数不适当得出性别对疗效影响的结论。
10 药物过量
在临床计划中1例患者接受过量2.5 mg/m2每天2次共5天。患者出现胃肠道功能紊乱,牙龈出血,脱发,和4级血小板减少和中性粒细胞减低。当SYNRIBO治疗被暂时中断胃肠道功能紊和出血综合征解决,和嗜中性值返回正常范围内。脱发和血小板减少(1级)改善,和SYNRIBO重新开始。
11 一般描述
SYNRIBO含活性成分omacetaxine mepesuccinate,一种三尖杉碱酯[cephalotaxine ester]。它是一种蛋白合成抑制剂。Omacetaxine mepesuccinate是通过从粗榧碱[cephalotaxine]半-合成过程制备,前者从三尖杉藻[Cephalotaxus sp]叶中萃取。Omacetaxine mepesuccinate的化学名是粗榧碱,4-methyl(2R)-hydroxyl-2-(4-hydroxyl-4-methylpentyl) butanedioate(ester)。
Omacetaxine mepesuccinate的结构式如下:
分子式C29H39NO9有分子量545.6 g/mol。SYNRIBO注射用是无菌,无防腐剂,白色至灰白色,冻干粉在单次使用小瓶中。各小瓶含3.5 mg omacetaxine mepesuccinate和甘露醇。SYNRIBO意向用1.0 mL的0.9%氯化钠注射液,USP重建后皮下给药。重建溶液的pH在5.5和7.0间。
12 临床药理学
12.1 作用机制
Omacetaxine mepesuccinate的作用机制尚未完全阐明但包括蛋白质合成的抑制及其独立直接cr-Abl结合作用。Omacetaxine mepesuccinate结合至来自一株古细菌[archaeabacteria]核糖体大亚单位[large ribosomal subunit]的中心肽基转移酶[peptidyl-transferase]中裂缝一个位点。在体外,omacetaxine mepesuccinate减低Bcr-Abl癌蛋白和Mcl-1的蛋白质水平,是抗凋亡Bcl-2一个家族成员。Omacetaxine mepesuccinate在野生型和T315I突变Bcr-Abl CML小鼠模型中显示活性。
12.3 药代动力学
不知道omacetaxine mepesuccinate的剂量正比例性。观察到在首次给药和稳态间omacetaxine mepesuccinate的全身暴露增加90%。
吸收 未曾测定omacetaxine mepesuccinate的绝对生物利用度。Omacetaxine mepesuccinate是从皮下给药吸收,和约30分钟后实现最大浓度。
分布 皮下给药1.25 mg/m2每天2次共11天Omacetaxine mepesuccinate的稳态(均数 ± SD)分布容积约为141 ± 93.4 L。Omacetaxine mepesuccinate的血浆蛋白结合是小于或等于50%.
代谢 在体外Omacetaxine mepesuccinate是主要通过血浆酯酶水解为4′-DMHHT与小量肝微粒体氧化和/或酯酶-介导代谢。
消除 不知道omacetaxine mepesuccinate的主要消除途径。在尿中排泄的未变化omacetaxine mepesuccinate平均百分率小于15%。皮下给药后omacetaxine mepesuccinate的半衰期为约6小时。
药物相互作用细胞色素P450酶(CYPs):在体外,Omacetaxine mepesuccinate不是CYP450酶的底物。临床上期望Omacetaxine mepesuccinate和4′-DMHHT浓度在体外不抑制主要CYPs。未测定omacetaxine mepesuccinate或4′-DMHHT诱导CYP450酶的潜能。
转运蛋白系统:在体外Omacetaxine mepesuccinate是P-糖蛋白(P-gp)的底物。临床上可期望的Omacetaxine mepesuccinate和4′-DMHHT浓度体外不抑制P-gp介导的洛哌丁胺[loperamide]的流出。
12.6 评估QT延长的风险
在21例接受omacetaxine mepesuccinate 1.25 mg/m2 BID共14连续天治疗患者的一项无对照药代动力学研究中未报道QTcF > 480 ms或ΔQTcF > 60 ms。对omacetaxine mepesuccinate或4’-DMHHT没有浓度-依赖性QTc的增加的证据。 虽然对QTc平均效应为4.2 ms(95% CI上限:9.5 ms),由于缺乏安慰剂和阳性对照QTc效应小于10 ms无法验证。
13 非临床毒理学
13.1 癌发生,突变发生,生育能力受损
未曾用omacetaxine mepesuccinate进行致癌性研究。
在中国仓鼠卵巢(CHO)细胞在体外染色体畸变测试系统Omacetaxine mepesuccinate是遗传毒性,但不是致突变性当在一种体外细菌细胞试验(Ames试验),和用一种体内小鼠微核试验不诱发遗传损伤。
SYNRIBO可能损害雄性生育能力。在小鼠中研究显示对雄性生殖器官不良效应。高剂量组(2.33 mg/kg/day 减低至1.67 mg/kg/day;7至5 mg/m2/day)在6个月期间皮下注射omacetaxine mepesuccinate共6个周期后,报道双侧睾丸中生精小管上皮细胞退行性变性和在附睾中精子减少/无精子。根据体表面积,在小鼠中所用该剂量约临床剂量(2.5 mg/m2/day)的2至3倍。
14 临床研究
用来自两项试验的一个CML成年患者合并队列评价SYNRIBO的疗效。合并队列包括患者曾接受2种或更多被批准酪氨酸激酶抑制和曾,最小,记录的对达沙替尼[dasatinib]和/或尼洛替尼[nilotinib]耐药或不能耐受的证据。耐药性被定义为以下之一:无完全血液学反应(CHR)共12周(是否丢失或从来未实现);或至24周无细胞遗传学反应(即,100% Ph阳性[Ph+])(是否丢失或从来未实现);或至52周无重大细胞遗传学反应(MCyR) (即,≥35% Ph+)(是否丢失或从来未实现);或进展性白细胞增多症。不能耐受被定义为以下之一:1) 3-4级非血液学毒性用适当干预没有解决;或2)4级血液学毒性持续7天以上;或3)对患者不能接受的任何≥ 2级毒性。排除有NYHA类别III或IV心脏病,活性缺血或其他未控制心脏情况患者。
用omacetaxine mepesuccinate在剂量1.25 mg/m2皮下给药每天2次每28天共连续14天(诱导疗程)治疗患者。反应患者然后用相同剂量和每天2次方案治疗每28天共连续7天(维持疗程)。允许患者继续接受维持治疗直至24个月。由一个独立数据监视委员会(DMC)裁决反应。
14.1 慢性期CML(CP CML)
在疗效分析中总共包括76例慢性期CML患者。人口统计指标为:中位年龄59岁,62%为男性,30%为年龄65岁或以上,80%为高加索人,5% 为非洲-美国人,4%为亚裔和4%为西班牙裔。36例(47%)患者曾用伊马替尼[imatinib],达沙替尼,和尼洛替尼治疗失败。大多数患者既往曾接受非-酪氨酸激酶抑制剂治疗,大多数常是羟基脲[hydroxyurea](54%),干扰素[interferon](30%),和/或阿糖胞苷[cytarabine](29%)。
疗效终点是根据MCyR(由独立数据监视委员会DMC裁决)。
在14例患者中平均至MCyR开始时间为3.5个月。对14例患者MCyR的中位时间为 12.5个月(Kaplan-Meier估计值)。
14.2 加速期CML(AP CML)
在疗效分析中总共包括35例有加速期CML患者。人口统计指标为:中位年龄63岁,57% 为男性,46%年龄为65岁或以上,68%为高加索人,23%为非洲每个人,3%为亚裔和3% 为西班牙裔。22/3例(63%)有加速期患者用伊马替尼,达沙替尼,和尼洛替尼治疗失败。大多数患者还曾接受既往非-酪氨酸激酶抑制剂治疗,大多数常为羟基脲(43%),干扰素(31%),和/或阿糖胞苷(29%)。评估疗效终点根据MCyR和MaHR(完全血液学反应[CHR]或无白血病证据[NEL])。表5中显示由独立数据监视委员会DMC对加速期患者裁决的疗效结果。
5例患者中平均反应开始时间为2.3个月。对5例患者MaHR的中位时间为4.7个月(Kaplan-Meier估计值)。

The recommended starting schedule for induction is 1.25 mg/m2 administered subcutaneously twice daily at approximately 12 hour intervals for 14 consecutive days every 28 days, over a 28-day cycle. Cycles should be repeated every 28 days until patients achieve a hematologic response
The recommended maintenance schedule is 1.25 mg/m2 administered subcutaneously twice daily at approximately 12 hour intervals for 7 consecutive days every 28 days, over a 28-day cycle. Treatment should continue as long as patients are clinically benefiting from therapy.
Dose Adjustments and ModificationsHematologic Toxicity:
Synribo treatment cycles may be delayed and/or the number of days of dosing during the cycle reduced for hematologic toxicities (e.g. neutropenia, thrombocytopenia) [see Warnings and Precautions (5.1)].
Perform complete blood counts (CBCs) weekly during induction and initial maintenance cycles. After initial maintenance cycles, monitor CBCs every two weeks or as clinically indicated. If a patient experiences Grade 4 neutropenia (absolute neutrophil count (ANC) less than 0.5 x 109/L) or Grade 3 thrombocytopenia (platelet counts less than 50 x 109/L) during a cycle, delay starting the next cycle until ANC is greater than or equal to 1.0 x 109/L and platelet count is greater than or equal to 50 x 109/L. Also, for the next cycle, reduce the number of dosing days by 2 days (e.g. to 12 or 5 days).
Non-Hematologic Toxicity:
Manage other clinically significant non-hematologic toxicity symptomatically. Interrupt and/or delay Synribo until toxicity is resolved.
Reconstitution Instructions and Handling PrecautionsSynribo should be prepared in a healthcare facility and must be reconstituted by a healthcare professional.
Reconstitute Synribo with one mL of 0.9% Sodium Chloride Injection, USP, prior to subcutaneous injection. After addition of the diluent, gently swirl until a clear solution is obtained. The lyophilized powder should be completely dissolved in less than one minute. The resulting solution is clear and colorless and contains 3.5 mg/mL Synribo. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.
Synribo does not contain antimicrobial preservatives. Therefore care must be taken to ensure that the solution for injection is not contaminated during preparation.
Synribo is a cytotoxic drug. Follow special handling and disposal procedures1. Wear protective eyewear and gloves during handling and administration of the product. Proper aseptic technique should be used. Avoid skin and eye contact. If Synribo comes into contact with skin, immediately and thoroughly wash affected area with soap and water. If contact with the eyes occurs, thoroughly flush the eyes with water.
Storage Conditions and Storage Time after Preparation of SyringesIf Synribo is not used immediately after reconstitution, follow in-use storage conditions and allowable storage times prior to use as instructed in Table 1. Do not administer Synribo outside of the storage conditions and timeframes listed in Table 1.

Use within 6 days (144 hours) of reconstitution |
Before a decision is made to allow Synribo to be administered by someone other than a healthcare professional, ensure that the patient is an appropriate candidate for self-administration or for administration by a caregiver. Provide training on proper handling, storage conditions, administration, disposal, and clean-up of accidental spillage of the product. Ensure that patients receive the necessary supplies for home administration. At minimum these should include:
•
Reconstituted Synribo in syringe with a capped needle for subcutaneous injection. Syringe(s) should be filled to the patient-specific dose.
•
Protective eyewear
•
Gloves
•
An appropriate biohazard container
•
Absorbent pad(s) for placement of administration materials and for accidental spillage
•
Alcohol swabs
•
Gauze pads
•
Ice packs or cooler for transportation of reconstituted Synribo syringes
If a patient or caregiver cannot be trained for any reason, then in such patients, Synribo should be administered by a healthcare professional.
Disposal and Accidental Spillage ProceduresAfter administration, any unused solution should be discarded properly1. Instruct patients planning home administration on the following: do not recap or clip the used needle, and do not place used needles, syringes, vials, and other used supplies in a household trash or recycling bin. Used needles, syringes, vials, and other used supplies should be disposed of in an appropriate biohazard container.
If accidental spillage occurs, continue to use protective eyewear and gloves, wipe the spilled liquid with the absorbent pad, and wash the area with water and soap. Then, place the pad and gloves into the biohazard container and wash hands thoroughly. Return the biohazard container to the clinic or pharmacy for final disposal.
Dosage Forms and StrengthsSynribo for Injection contains 3.5 mg omacetaxine mepesuccinate; as a sterile, preservative-free, white to off-white lyophilized powder in a single-dose vial.
ContraindicationsNone.
Warnings and PrecautionsMyelosuppressionIn uncontrolled trials with Synribo, patients with chronic phase and accelerated phase CML experienced NCI CTC (version 3.0) Grade 3 or 4 thrombocytopenia (85%, 88%), neutropenia (81%, 71%), and anemia (62%, 80%), respectively. Fatalities related to myelosuppression occurred in 3% of patients in the safety population (N=163). Patients with neutropenia are at increased risk for infections, and should be monitored frequently and advised to contact a physician if they have symptoms of infection or fever.
Monitor complete blood counts weekly during induction and initial maintenance cycles and every two weeks during later maintenance cycles, as clinically indicated. In clinical trials myelosuppression was generally reversible and usually managed by delaying next cycle and/or reducing days of treatment with Synribo [see Dosage and Administration (2.3) and Adverse Reactions (6.1)].
BleedingSynribo causes severe thrombocytopenia which increases the risk of hemorrhage. In clinical trials with CP and AP CML patients, a high incidence of Grade 3 and 4 thrombocytopenia (85% and 88%, respectively) was observed. Fatalities from cerebral hemorrhage occurred in 2% of patients treated with Synribo in the safety population. Severe, non-fatal, gastrointestinal hemorrhages occurred in 2% of patients in the same population. Most bleeding events were associated with severe thrombocytopenia.
Monitor platelet counts as part of the CBC monitoring as recommended [see Warnings and Precautions (5.1)]. Avoid anticoagulants, aspirin, and non-steroidal anti-inflammatory drugs (NSAIDs) when the platelet count is less than 50,000/µL as they may increase the risk of bleeding.
HyperglycemiaSynribo can induce glucose intolerance. Grade 3 or 4 hyperglycemia was reported in 11% of patients in the safety population. Hyperosmolar non-ketotic hyperglycemia occurred in 1 patient treated with Synribo in the safety population. Monitor blood glucose levels frequently, especially in patients with diabetes or risk factors for diabetes. Avoid Synribo in patients with poorly controlled diabetes mellitus until good glycemic control has been established.
Embryo-Fetal ToxicitySynribo can cause fetal harm when administered to a pregnant woman. Omacetaxine mepesuccinate caused embryo-fetal death in animals. Females of reproductive potential should avoid becoming pregnant while being treated with Synribo. There are no adequate and well-controlled studies of Synribo in pregnant women. If this drug is used during pregnancy, or if the patient becomes pregnant while receiving this drug, the patient should be apprised of the potential hazard to the fetus [see Use in Specific Populations (8.1)].
Adverse ReactionsThe following serious adverse reactions have been associated with Synribo in clinical trials and are discussed in greater detail in other sections of the label.
•
Myelosuppression [see Warnings and Precautions (5.1)]
•
Bleeding [see Warnings and Precautions (5.2)]
•
Hyperglycemia [see Warnings and Precautions (5.3)]
Clinical Trials ExperienceBecause clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety data for Synribo are from 3 clinical trials which enrolled a total of 163 adult patients with TKI resistant and/or intolerant chronic phase (N=108) and accelerated phase (N=55) CML. All patients were treated with initial induction therapy consisting of a dose of 1.25 mg/m2 administered subcutaneously twice daily for 14 consecutive days every 28 days (induction cycle). Responding patients were then treated with the same dose and a twice daily schedule for 7 consecutive days every 28 days (maintenance cycle).
Chronic Phase CML
The median duration of exposure for the 108 patients with chronic phase CML was 7.4 months (range 0 to 43 months). The median total cycles of exposure was 6 (range 1 to 41), and the median total dose delivered during the trials was 131 mg/m2 (range 1.2 to 678). Among the patients with chronic phase CML, 87% received 14 days of treatment during cycle 1. By cycles 2 and 3, the percentage of patients receiving 14 days of treatment decreased to 42% and 16% respectively. Of the 91 patients who received at least 2 cycles of treatment, 79 (87%) had at least 1 cycle delay during the trials. The median number of days of cycle delays was greatest for cycle 2 (17 days) and cycle 3 (25 days) when more patients were receiving induction cycles.
Adverse reactions were reported for 99% of the patients with chronic phase CML. A total of 18% of patients had adverse reactions leading to withdrawal. The most frequently occurring adverse reactions leading to discontinuation were pancytopenia, thrombocytopenia, and increased alanine aminotransferase (each 2%). A total of 87% of patients reported at least 1 Grade 3 or Grade 4 treatment emergent adverse reaction (Table 2).

Serious adverse reactions were reported for 51% of patients. Serious adverse reactions reported for at least 5% of patients were bone marrow failure and thrombocytopenia (each 10%), and febrile neutropenia (6%). Serious adverse reactions of infections were reported for 8% of patients.
Deaths occurred while on study in five (5%) patients with CP CML. Two patients died due to cerebral hemorrhage, one due to multi-organ failure, one due to progression of disease, and one from unknown causes.
Accelerated Phase CML
Median total cycles of exposure was 2 (range 1 to 29), and the median total dose delivered during the trials was 70 mg/m2. The median duration of exposure for the 55 patients with accelerated phase CML was 1.9 months (range 0 to 30 months). Of the patients with accelerated phase CML, 86% received 14 days of treatment during cycle 1. By cycles 2 and 3, the percentage of patients receiving 14 days of treatment decreased to 55% and 44% respectively. Of the 40 patients who received at least 2 cycles of treatment, 27 (68%) had at least 1 cycle delay during the trials. The median number of days of cycle delays was greatest for cycle 3 (31 days) and cycle 8 (36 days).
Adverse reactions regardless of investigator attribution were reported for 100% patients with accelerated phase CML. A total of 33% of patients had adverse reactions leading to withdrawal. The most frequently occurring adverse reactions leading to withdrawal were leukocytosis (6%), and thrombocytopenia (4%). A total of 84% of patients reported at least 1 Grade 3 or Grade 4 treatment emergent adverse reaction (Table 3).

Serious adverse reactions were reported for 60% of patients. Serious adverse reactions reported for at least 5% of patients were febrile neutropenia (18%), thrombocytopenia (9%), anemia (7%), and diarrhea (6%). Serious adverse reactions of infections were reported for 11% of patients.
Death occurred while on study in 5 (9%) patients with AP CML. Two patients died due to cerebral hemorrhage and three due to progression of disease.
Laboratory Abnormalities in Chronic and Accelerated Phase CML
Grade 3/4 laboratory abnormalities reported in patients with chronic and accelerated phase CML are described in Table 4. Myelosuppression occurred in all patients treated with Synribo [see Warnings and Precautions (5.1)]. Five patients with chronic phase CML and 4 patients with accelerated phase CML permanently discontinued Synribo due to pancytopenia, thrombocytopenia, febrile neutropenia, or bone marrow necrosis. An event of hyperosmolar non-ketotic hyperglycemia was reported in one patient in the safety population and a similar case has been reported in the literature. Two patients with chronic phase CML permanently discontinued Synribo due to elevated transaminases.

USE IN SPECIFIC POPULATIONSPregnancyPregnancy Category D [see Warnings and Precautions (5.4)]
Risk Summary
Based on its mechanism of action and findings from animal studies, Synribo can cause fetal harm when administered to pregnant women. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus.
Animal Data
In an embryo-fetal development study, pregnant mice were administered omacetaxine mepesuccinate subcutaneously during the period of organogenesis at doses of 0.21 or 0.41 mg/kg/day. Drug-related adverse effects included embryonic death, an increase in unossified bones/reduced bone ossification and decreased fetal body weights. Fetal toxicity occurred at doses of 0.41 mg/kg (1.23 mg/m2) which is approximately half the recommended daily human dose on a body surface area basis.
Nursing MothersIt is not known whether omacetaxine mepesuccinate is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reaction in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric UseThe safety and effectiveness of Synribo in pediatric patients have not been established.
Geriatric UseIn the chronic and accelerated phase CML efficacy populations 23 (30%) and 16 (46%) patients were ≥65 years of age. For the age subgroups of <65 years of age and ≥65 years of age, there were differences between the subgroups, with higher rates of major cytogenetic responses (MCyRs) in younger patients with CP CML compared with older patients (23% vs. 9%, respectively) and higher rates of major hematologic responses (MaHRs) in older patients with AP CML compared with younger patients (31% vs. 0%, respectively). Patients ≥65 years of age were more likely to experience toxicity, most notably hematologic toxicity.
Effect of GenderOf the 76 patients included in the chronic phase CML population efficacy analysis, 47 (62%) of the patients were men and 29 (38%) were women. For patients with chronic phase CML, the MCyR rate in men was higher than in women (21% vs. 14%, respectively). There were differences noted in the safety profile of omacetaxine mepesuccinate in men and women with chronic phase CML although the small number of patients in each group prevents a definitive assessment. There were inadequate patient numbers in the accelerated phase subset to draw conclusions regarding a gender effect on efficacy.
OverdosageA patient in the clinical expanded access program received an overdose of 2.5 mg/m2 twice daily for 5 days in the 16th cycle. The patient presented with gastrointestinal disorders, gingival hemorrhage, alopecia, and Grade 4 thrombocytopenia and neutropenia. When Synribo treatment was temporarily interrupted the gastrointestinal disorders and hemorrhagic syndrome resolved, and neutrophil values returned to within normal range. The alopecia and thrombocytopenia (Grade 1) improved, and Synribo was restarted.
No specific antidote for Synribo overdose is known. Management of overdosage should include general supportive measures, including monitoring of hematologic parameters.
Synribo DescriptionSynribo contains the active ingredient omacetaxine mepesuccinate, a cephalotaxine ester. It is a protein synthesis inhibitor. Omacetaxine mepesuccinate is prepared by a semi-synthetic process from cephalotaxine, an extract from the leaves of Cephalotaxus sp. The chemical name of omacetaxine mepesuccinate is cephalotaxine, 4-methyl (2R)-hydroxyl-2-(4-hydroxyl-4-methylpentyl) butanedioate (ester).
Omacetaxine mepesuccinate has the following chemical structure:
The molecular formula is C29H39NO9 with a molecular weight of 545.6 g/mol. Synribo for Injection is a sterile, preservative-free, white to off-white, lyophilized powder in a single-dose vial. Each vial contains 3.5 mg omacetaxine mepesuccinate and mannitol.
Synribo is intended for subcutaneous administration after reconstitution with 1.0 mL of 0.9% Sodium Chloride Injection, USP. The pH of the reconstituted solution is between 5.5 and 7.0.
Synribo - Clinical PharmacologyMechanism of ActionThe mechanism of action of omacetaxine mepesuccinate has not been fully elucidated but includes inhibition of protein synthesis and is independent of direct Bcr-Abl binding. Omacetaxine mepesuccinate binds to the A-site cleft in the peptidyl-transferase center of the large ribosomal subunit from a strain of archaeabacteria. In vitro, omacetaxine mepesuccinate reduced protein levels of the Bcr-Abl oncoprotein and Mcl-1, an anti-apoptotic Bcl-2 family member. Omacetaxine mepesuccinate showed activity in mouse models of wild-type and T315I mutated Bcr-Abl CML.
PharmacodynamicsCardiac Electrophysiology
In an uncontrolled pharmacokinetic study there were no reports of QTcF > 480 ms or ΔQTcF > 60 ms in 21 treated patients who received omacetaxine mepesuccinate 1.25 mg/m2 BID for 14 consecutive days. There was no evidence for concentration-dependent increases in QTc for omacetaxine mepesuccinate or 4’-DMHHT. Although the mean effect on QTc was 4.2 ms (upper 95% CI: 9.5 ms), QTc effects less than 10 ms cannot be verified due to the absence of a placebo and positive controls.
PharmacokineticsThe dose proportionality of omacetaxine mepesuccinate is unknown. A 90% increase in systemic exposure to omacetaxine mepesuccinate was observed between the first dose and steady state.
Absorption
The absolute bioavailability of omacetaxine mepesuccinate has not been determined. Omacetaxine mepesuccinate is absorbed following subcutaneous administration, and maximum concentrations are achieved after approximately 30 minutes.
Distribution
The steady-state (mean ± SD) volume of distribution of omacetaxine mepesuccinate is approximately 141 ± 93.4 L following subcutaneous administration of 1.25 mg/m2 twice daily for 11 days . The plasma protein binding of omacetaxine mepesuccinate is less than or equal to 50%.
Elimination
The terminal elimination half-life of omacetaxine mepesuccinate in plasma is 14.6 hours.
Metabolism
Omacetaxine mepesuccinate is primarily hydrolyzed to 4′-DMHHT via plasma esterases with little hepatic microsomal oxidative and/or esterase-mediated metabolism in vitro.
Excretion
Following a single subcutaneous dose of radiolabeled omacetaxine mepesuccinate, the mean total recovery of radioactivity in excreta was approximately 81% of the radioactive dose. Approximately 37% of the radioactivity was recovered in urine and approximately 44% in feces.
Drug Interaction Studies
Cytochrome P450 (CYP) Enzymes: Omacetaxine mepesuccinate and 4′-DMHHT do not inhibit major CYP enzymes in vitro at concentrations that can be expected clinically. The potential for omacetaxine mepesuccinate or 4′-DMHHT to induce CYP enzymes has not been determined.
Transporter Systems: Omacetaxine mepesuccinate is a P-glycoprotein (P-gp) substrate in vitro. Omacetaxine mepesuccinate and 4′-DMHHT do not inhibit P-gp mediated efflux of loperamide in vitro at concentrations that can be expected clinically.
Nonclinical ToxicologyCarcinogenesis, Mutagenesis, Impairment of FertilityNo carcinogenicity studies have been conducted with omacetaxine mepesuccinate.
Omacetaxine mepesuccinate was genotoxic in an in vitro chromosomal aberration test system in Chinese hamster ovary (CHO) cells, but was not mutagenic when tested in an in vitro bacterial cell assay (Ames test), and it did not induce genetic damage using an in vivo mouse micronucleus assay.
Synribo may impair male fertility. Studies in mice demonstrated adverse effects on male reproductive organs. Bilateral degeneration of the seminiferous tubular epithelium in testes and hypospermia/aspermia in the epididymides were reported in the highest dose group (2.33 mg/kg/day reduced to 1.67 mg/kg/day; 7 to 5 mg/m2/day) following subcutaneous injection of omacetaxine mepesuccinate for six cycles over six months. The doses used in the mice were approximately two to three times the clinical dose (2.5 mg/m2/day) based on body surface area.
Clinical StudiesThe efficacy of Synribo was evaluated using a combined cohort of adult patients with CML from two trials. The combined cohort consisted of patients who had received 2 or more approved TKIs and had, at a minimum, documented evidence of resistance or intolerance to dasatinib and/or nilotinib. Resistance was defined as one of the following: no complete hematologic response (CHR) by 12 weeks (whether lost or never achieved); or no cytogenetic response by 24 weeks (i.e., 100% Ph positive [Ph+]) (whether lost or never achieved); or no major cytogenetic response (MCyR) by 52 weeks (i.e., ≥35% Ph+) (whether lost or never achieved); or progressive leukocytosis. Intolerance was defined as one of the following: 1) Grade 3-4 non-hematologic toxicity that does not resolve with adequate intervention; or 2) Grade 4 hematologic toxicity lasting more than 7 days; or 3) any Grade ≥ 2 toxicity that is unacceptable to the patient. Patients with NYHA class III or IV heart disease, active ischemia or other uncontrolled cardiac conditions were excluded.
Patients were treated with omacetaxine mepesuccinate at a dose of 1.25 mg/m2 administered subcutaneously twice daily for 14 consecutive days every 28 days (induction cycle). Responding patients were then treated with the same dose and twice daily schedule for 7 consecutive days every 28 days (maintenance cycle). Patients were allowed to continue to receive maintenance treatment for up to 24 months. Responses were adjudicated by an independent Data Monitoring Committee (DMC).
Chronic Phase CML (CP CML)
A total of 76 patients with chronic phase CML were included in the efficacy analysis. The demographics were: median age 59 years, 62% were male, 30% were 65 years of age or older, 80% were Caucasian, 5% were African-American, 4% were Asian and 4% were Hispanic. Thirty-six (47%) patients had failed treatment with imatinib, dasatinib, and nilotinib. Most patients had also received prior non-TKI treatments, most commonly hydroxyurea (54%), interferon (30%), and/or cytarabine (29%). The efficacy endpoint was based on MCyR (adjudicated by a DMC).

Cytogenetic response evaluation is based on standard cytogenetic analysis (at least 20 metaphases).
Complete: 0% Ph+ cells, Partial > 0% to 35% Ph+ cells
The mean time to MCyR onset in the 14 patients was 3.5 months. The median duration of MCyR for the 14 patients was 12.5 months (Kaplan-Meier estimate).
Accelerated Phase CML (AP CML)
A total of 35 patients with accelerated phase CML were included in the efficacy analysis. The demographics were: median age was 63 years, 57% were male, 46% were 65 years of age or older, 68% were Caucasian, 23% were African-American, 3% were Asian and 3% were Hispanic. Twenty-two (63%) of 35 patients with accelerated phase had failed treatment with imatinib, dasatinib, and nilotinib. Most patients had also received prior non-TKI treatments, most commonly hydroxyurea (43%), interferon (31%), and/or cytarabine (29%). The efficacy endpoint was assessed based on MCyR and MaHR (complete hematologic response [CHR] or no evidence of leukemia [NEL]). The efficacy results for the patients with accelerated phase as adjudicated by the DMC are shown in Table 6.
