6.1 临床实验经验
因为临床试验是在广泛不同情况下进行的,CRESEMBA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。
下面描述数据反映在一项开放,随机化(研究1)或单臂临床试验(研究2和研究3) 在推荐剂量和时间表在1021例被纳入有高风险神经母细胞瘤患者对Unituxin的暴露。纳入前,患者接受治疗由诱导联合化疗,最大可行手术切除,清髓巩固化疗接着自体造血干细胞移植,和放疗对残余软组织疾病所组成。患者接受Unituxin与粒细胞 - 巨噬细胞集落刺激因子(GM-CSF),白介素-2(IL-2)和13-顺 - 视黄酸(RA)联用。在研究1中自体造血干细胞移植开始95天内后治疗,在研究2中自体造血干细胞移植210天内,而在研究3中自体造血干细胞移植110天内。
研究1
在一项随机化,开放,多中心研究(研究1),134例患者接受dinutuximab与GM-CSF,IL-2和RA(Unituxin/RA组)联用,包括109例随机化患者和25例患者有活检-证明的残留疾病被非-随机赋予接受dinutuximab。总共106例随机化患者单独接受RA(RA组)[见剂量和给药方法(2)和临床研究(14)]。在纳入时患者有中位年龄3.8岁(范围:0.94至15.3岁),和主要是男性(60%)和白种人(82%). 在研究1中,3级或以上严重程度不良反应被全面收集,但1或2级不良反应严重程度 被零星收集和没有全面地收集实验室数据。
在Unituxin/RA组约71%患者和在RA组77%患者完成计划治疗。在Unituxin/RA组为提早终止研究治疗最常见理由是不良反应(19%)和在RA组为进展疾病(17%)。
在Unituxin/RA组最常见不良药物反应(≥ 25%)是疼痛,发热,血小板减少,淋巴细胞减少,输注反应,低血压,低钠血症,谷丙转氨酶增加,贫血,呕吐,腹泻,低钾血症,毛细血管渗漏综合征,中性粒细胞减少,荨麻疹,低白蛋白血症,谷草转氨酶增加,和低钙血症。在Unituxin/RA组最常见严重不良反应(≥ 5%)是感染,输注反应,低钾血症,低血压,疼痛,发热,和毛细血管渗漏综合征。
表5列出在Unituxin/RA组报道的不良反应在至少10%患者其中有组间差别至少5%(所有级别)或2%(3级或以上严重程度)。
表6 比较含dinutuximab与联用GM-CSF疗程(疗程1,3,和5)用含dinutuximab与联用IL-2(疗程2和4)疗程期间选定不良反应的每患者发生率。
研究2和研究3
研究2是一项单臂,多中心扩展评估试验纳入有高风险神经母细胞瘤患者(N=783)。在研究2中被报道的dinutuximab不良事件图形与在研究1中观察到相似。
研究3是一项多中心,单臂dinutuximab与GM-CSF,IL-2和RA联用安全性研究。在研究3中,系统和全面地收集所有CTCAE级别的不良事件和实验室数据。在研究3中纳入和治疗的104例患者中,77%患者完成研究治疗。一般而言,在研究3中观察到dinutuximab的不良反应图形与在研究1中和研究2观察到相似。在研究3中以下不良反应在研究1中在至少10%患者以前没有报告过:鼻塞(20%)和喘息(15%)。表7提供在研究3中实验室异常每患者发生率,
6.2 免疫原性
如同所有治疗性蛋白,用Unituxin治疗患者可能发生抗-药物抗体。在临床研究中,来自研究252/284(18%)患者和来自研究3的13/103例(13%)患者对抗-dinutuximab结合抗体测试阳性。在研究2中和研究3中对抗-dinutuximab结合抗体测试3.6%患者被检测。但是,由于分析的缺限,不可能可靠地测定中和抗体的发生率。
抗体形成的检测高度依赖于分析的灵敏度和特异性。此外,在某个分析中观察到抗体的发生率(包括中和抗体)可能受几种因子影响包括分析方法学,样品处置,采样时间,同时药物,和所患疾病。因为这些原因,比较对Unituxin抗体发生率与对其他产品抗体的发生率可能是误导。
7 药物相互作用
未曾用dinutuximab进行药物-药物相互作用研究。
8 在特殊人群中使用
8.1 妊娠
风险总结
根据其作用机制,当给予至某个妊娠妇女Unituxin可能致胎儿危害[见临床药理学(12.1)]。没有在妊娠妇女研究和在动物中没有生殖研究告知药物关联风险。单克隆抗体跨越胎盘转运以线性形式当妊娠进展,在妊娠第三个三个月转运量最大。忠告妊娠妇女对胎儿潜在风险。不知道对适用人群主要出生缺陷和流产的背景风险。但是,在美国一般人群主要出生缺陷背景风险是2-4%和流产是临床上识别妊娠的15-20%。
8.2 哺乳
风险总结
在人乳汁中dinutuximab的存在,药物对哺乳喂养婴儿的影响,或药物对乳汁生成的影响没有可得到的信息。但是,人乳汁存在IgG。因为对哺乳喂养婴儿中严重不良反应潜能,忠告一位哺乳妇女用Unituxin治疗期间终止哺乳喂养。

11 一般描述
Unituxin(dinutuximab)是一个嵌合体单克隆抗体由鼠类可变重和轻链区和对重链IgG1和轻链kappa人恒定区组成。Unituxin结合至糖脂二唾液酸神经节苷脂(GD2)。Dinutuximab是在鼠类骨髓瘤细胞系,SP2/0中生产。
Unituxin是一种无菌,无防腐剂,清澈/无色至轻微乳白色溶液为静脉输注。Unituxin在单次-使用17.5 mg/5mL小瓶供应。每小瓶含3.5 mg/mL的dinutuximab,组氨酸(20mM),聚山梨醇20(0.05%),氯化钠(150 mM),和注射用水;加入盐酸以调节pH至6.8。
12 临床药理学
12.1 作用机制
Dinutuximab与糖脂GD2结合。神经母细胞瘤细胞上和神经外胚层来源正常细胞上,包括中枢神经系统和周边神经,表达这个糖脂。Dinutuximab结合至细胞表面GD2和诱导GD2表达细胞至抗体-依赖细胞-介导细胞毒性(ADCC)和补体-依赖细胞毒性(CDC)的细胞溶解。
12.3 药代动力学
通过在一项Unituxin与GM-CSF,IL-2,和RA联用的临床研究一个群体药代动力学分析评价dinutuximab的药代动力学。在这项研究中,27例有高风险神经母细胞瘤儿童(年龄:3.9±1.9 岁) 接受直至5个疗程的Unituxin在17.5 mg/m2/day作为历时10至20小时静脉输注共4连续天每28 天。观察的最高血浆dinutuximab浓度(Cmax )为11.5 µg/mL[20%,变异系数(CV)]。在稳态均数分布容积(Vdss)是5.4 L(28%)。清除率为0.21 L/day(62%)和随机体大小增加。末端半衰期是10 天(56%),
在有肾或肝受损患者中未进行正式药代动力学研究。
13 非临床毒理学
13.1 癌发生,突变发生,生育力受损
未进行动物研究评价dinutuximab的致癌性或致突变性潜能。
未在动物中进行专门研究检查dinutuximab对生育力的影响。在大鼠进行一般毒理学研究未观察到对生殖器官明确的影响。
13.2 动物毒理学和/或药理学
非-临床研究提示dinutuximab-诱导神经病性疼痛是通过抗体与位于周边神经纤维和髓鞘的表面GD2抗原结合介导和随后补体依赖细胞毒性[CDC]和抗体-依赖细胞-介导细胞毒性[ADCC] 活性的诱导作用。
14 临床研究
在一项随机化,开放,多中心试验,在有高风险神经母细胞瘤儿童患者中进行Unituxin的安全性和有效性评价(研究1)。所有患者曾接受以前治疗诱导联合化疗,最大可行手术切除,清髓巩固化疗组成接着通过自体造血干细胞移植,和对残余软组织疾病放疗。第50天和第77天间自体造血干细胞移植后患者被随机化。
患者对自体造血干细胞移植前被要求有实现至少一个以前的部分缓解反应,第一线多种-模式治疗的完成后无疾病进展的证据,有适当的肺功能(在休息时无呼吸困难和对室空气周边动脉氧饱和度至少94%),适当的肝功能(总胆红素 < 1.5 × 正常上限和ALT < 5 × 正常上限),适当的心功能(通过超声心图缩短分数 > 30%,或如缩短分量异常,通过门控核素研究射血分数55%),和适当的肾功能(肾小球滤过率至少70 mL/min/1.73 m2)。有全身感染患者或一个对同时全身皮质激素需求或免疫抑制剂的使用对纳入是不合格的。

Generic
Name: dinutuximab
Dosage Form: injection
WARNING: SERIOUS INFUSION REACTIONS AND NEUROTOXICITY
Infusion Reactions
· Serious and potentially life-threatening infusion reactions occurred in 26% of patients treated with Unituxin. Administer required prehydration and premedication including antihistamines prior to each Unituxin infusion. Monitor patients closely for signs and symptoms of an infusion reaction during and for at least four hours following completion of each Unituxin infusion. Immediately interrupt Unituxin for severe infusion reactions and permanently discontinue Unituxin for anaphylaxis (2.2, 2.3, 5.1).
Neurotoxicity
· Unituxin causes serious neurologic adverse reactions including severe neuropathic pain and peripheral neuropathy.
Severe neuropathic pain occurs in the majority of patients. Administer intravenous opioid prior to, during, and for 2 hours following completion of the Unituxin infusion.
In clinical studies of patients with high-risk neuroblastoma, Grade 3 peripheral sensory neuropathy occurred in 2% to 9% of patients. In clinical studies of Unituxin and related GD2-binding antibodies, severe motor neuropathy has occurred. Resolution of motor neuropathy did not occur in all cases. Discontinue Unituxin for severe unresponsive pain, severe sensory neuropathy, and moderate to severe peripheral motor neuropathy (2.2, 2.3, 5.2).
Indications and Usage for Unituxin
Unituxin (dinutuximab) is indicated, in combination with granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin-2 (IL-2) and 13-cis-retinoic acid (RA), for the treatment of pediatric patients with high-risk neuroblastoma who achieve at least a partial response to prior first-line multiagent, multimodality therapy [see Clinical Studies (14)].
Unituxin Dosage and Administration
· Verify that patients have adequate hematologic, respiratory, hepatic, and renal function prior to initiating each course of Unituxin [see Clinical Studies (14)].
· Administer required premedication and hydration prior to initiation of each Unituxin infusion [see Dosage and Administration (2.2)].
Recommended Dose
· The recommended dose of Unituxin is 17.5 mg/m2/day administered as an intravenous infusion over 10 to 20 hours for 4 consecutive days for a maximum of 5 cycles (Tables 1 and 2 ) [see Dosage and Administration (2.4) and Clinical Studies (14)].
· Initiate at an infusion rate of 0.875 mg/m2/hour for 30 minutes. The infusion rate can be gradually increased as tolerated to a maximum rate of 1.75 mg/m2/hour. Follow dose modification instructions for adverse reactions [see Dosage and Administration (2.3)].

Warnings and PrecautionsSerious Infusion Reactions
Serious infusion reactions requiring urgent intervention including blood pressure support, bronchodilator therapy, corticosteroids, infusion rate reduction, infusion interruption, or permanent discontinuation of Unituxin included facial and upper airway edema, dyspnea, bronchospasm, stridor, urticaria, and hypotension. Infusion reactions generally occurred during or within 24 hours of completing the Unituxin infusion. Due to overlapping signs and symptoms, it was not possible to distinguish between infusion reactions and hypersensitivity reactions in some cases.
In Study 1, Severe (Grade 3 or 4) infusion reactions occurred in 35 (26%) patients in the Unituxin/13-cis-retinoic acid (RA) group compared to 1 (1%) patient receiving RA alone. Severe urticaria occurred in 17 (13%) patients in the Unituxin/RA group but did not occur in the RA group. Serious adverse reactions consistent with anaphylaxis and resulting in permanent discontinuation of Unituxin occurred in 2 (1%) patients in the Unituxin/RA group. Additionally, 1 (0.1%) patient had multiple cardiac arrests and died within 24 hours after having received Unituxin in Study 2.
Prior to each Unituxin dose, administer required intravenous hydration and premedication with antihistamines, analgesics, and antipyretics [see Dosage and Administration (2.2)]. Monitor patients closely for signs and symptoms of infusion reactions during and for at least 4 hours following completion of each Unituxin infusion in a setting where cardiopulmonary resuscitation medication and equipment are available.
For mild to moderate infusion reactions such as transient rash, fever, rigors, and localized urticaria that respond promptly to antihistamines or antipyretics, decrease the Unituxin infusion rate and monitor closely. Immediately interrupt or permanently discontinue Unituxin and institute supportive management for severe or prolonged infusion reactions. Permanently discontinue Unituxin and institute supportive management for life-threatening infusion reactions [see Dosage and Administration (2.3)].
Neurotoxicity
Pain
In Study 1, 114 (85%) patients treated in the Unituxin/RA group experienced pain despite pre-treatment with analgesics including morphine sulfate infusion. Severe (Grade 3) pain occurred in 68 (51%) patients in the Unituxin/RA group compared to 5 (5%) patients in the RA group. Pain typically occurred during the Unituxin infusion and was most commonly reported as abdominal pain, generalized pain, extremity pain, back pain, neuralgia, musculoskeletal chest pain, and arthralgia.
Premedicate with analgesics including intravenous opioids prior to each dose of Unituxin and continue analgesics until two hours following completion of Unituxin [see Dosage and Administration (2.2)].
For severe pain, decrease the Unituxin infusion rate to 0.875 mg/m2/hour. Discontinue Unituxin if pain is not adequately controlled despite infusion rate reduction and institution of maximum supportive measures [see Dosage and Administration (2.3)].
Peripheral Neuropathy
In Study 1, severe (Grade 3) peripheral sensory neuropathy occurred in 2 (1%) patients and severe peripheral motor neuropathy occurred in 2 (1%) patients in the Unituxin/RA group. No patients treated with RA alone experienced severe peripheral neuropathy. The duration and reversibility of peripheral neuropathy occurring in Study 1 was not documented. In Study 3, no patients experienced peripheral motor neuropathy. Among the 9 (9%) patients who experienced peripheral sensory neuropathy of any severity, the median (min, max) duration of peripheral sensory neuropathy was 9 (3, 163) days.
In a study of a related anti-GD2 antibody conducted in 12 adult patients with metastatic melanoma, 2 (13%) patients developed severe motor neuropathy. One patient developed lower extremity weakness and inability to ambulate that persisted for approximately 6 weeks. Another patient developed severe lower extremity weakness resulting in an inability to ambulate without assistance that lasted for approximately 16 weeks and neurogenic bladder that lasted for approximately 3 weeks. Complete resolution of motor neuropathy was not documented in this case.
Permanently discontinue Unituxin in patients with peripheral motor neuropathy of Grade 2 or greater severity, Grade 3 sensory neuropathy that interferes with daily activities for more than 2 weeks, or Grade 4 sensory neuropathy [see Dosage and Administration (2.3)].
Neurological Disorders of the Eye
Neurological disorders of the eye experienced by two or more patients treated with Unituxin in Studies 1, 2, or 3 included blurred vision, photophobia, mydriasis, fixed or unequal pupils, optic nerve disorder, eyelid ptosis, and papilledema.
In Study 1, 3 (2%) patients in the Unituxin/RA group experienced blurred vision, compared to no patients in the RA group. Diplopia, mydriasis, and unequal pupillary size occurred in 1 patient each in the Unituxin/RA group, compared to no patients in the RA group. The duration of eye disorders occurring in Study 1 was not documented. In Study 3, eye disorders occurred in 16 (15%) patients, and in 3 (3%) patients resolution of the eye disorder was not documented. Among the cases with documented resolution, the median duration of eye disorders was 4 days (range: 0, 221 days).
Interrupt Unituxin in patients experiencing dilated pupil with sluggish light reflex or other visual disturbances that do not cause visual loss. Upon resolution and if continued treatment with Unituxin is warranted, decrease the Unituxin dose by 50%. Permanently discontinue Unituxin in patients with recurrent signs or symptoms of an eye disorder following dose reduction and in patients who experience loss of vision [see Dosage and Administration (2.3)].
Prolonged Urinary Retention
Urinary retention that persists for weeks to months following discontinuation of opioids has occurred in patients treated with Unituxin. Permanently discontinue Unituxin in patients with urinary retention that does not resolve following discontinuation of opioids [see Dosage and Administration (2.3) and Postmarketing Experience (6.3)].
Transverse Myelitis
Transverse myelitis has occurred in patients treated with Unituxin. Promptly evaluate any patient with signs or symptoms of transverse myelitis such as weakness, paresthesia, sensory loss, or incontinence. Permanently discontinue Unituxin in patients who develop transverse myelitis [see Dosage and Administration (2.3) and Postmarketing Experience (6.3)].
Reversible Posterior Leukoencephalopathy Syndrome
Reversible Posterior Leukoencephalopathy Syndrome (RPLS) has occurred in patients treated with Unituxin. Institute appropriate medical treatment and permanently discontinue Unituxin in patients with signs and symptoms of RPLS (e.g., severe headache, hypertension, visual changes, lethargy, or seizures) [see Dosage and Administration (2.3) and Postmarketing Experience (6.3)].
Capillary Leak Syndrome
In Study 1, severe (Grade 3 to 5) capillary leak syndrome occurred in 31 (23%) patients in the Unituxin/RA group and in no patients treated with RA alone. Additionally, capillary leak syndrome was reported as a serious adverse reaction in 9 (6%) patients in the Unituxin/RA group and in no patients treated with RA alone. Immediately interrupt or discontinue Unituxin and institute supportive management in patients with symptomatic or severe capillary leak syndrome [see Dosage and Administration (2.3)].
Hypotension
In Study 1, severe (Grade 3 or 4) hypotension occurred in 22 (16%) patients in the Unituxin/RA group compared to no patients in the RA group.
Prior to each Unituxin infusion, administer required intravenous hydration. Closely monitor blood pressure during Unituxin treatment. Immediately interrupt or discontinue Unituxin and institute supportive management in patients with symptomatic hypotension, systolic blood pressure (SBP) less than lower limit of normal for age, or SBP that is decreased by more than 15% compared to baseline [see Dosage and Administration (2.2, 2.3)].
Infection
In Study 1, severe (Grade 3 or 4) bacteremia requiring intravenous antibiotics or other urgent intervention occurred in 17 (13%) patients in the Unituxin/RA group compared to 5 (5%) patients treated with RA alone. Sepsis occurred in 24 (18%) patients in the Unituxin/RA group and in 10 (9%) patients in the RA group.
Monitor patients closely for signs and symptoms of systemic infection and temporarily discontinue Unituxin in patients who develop systemic infection until resolution of the infection [see Dosage and Administration (2.3)].
Bone Marrow Suppression
In Study 1, severe (Grade 3 or 4) thrombocytopenia (39% vs. 25%), anemia (34% vs. 16%), neutropenia (34% vs. 13%), and febrile neutropenia (4% vs. 0 patients) occurred more commonly in patients in the Unituxin/RA group compared to patients treated with RA alone. Monitor peripheral blood counts closely during therapy with Unituxin.
Electrolyte Abnormalities
Electrolyte abnormalities occurring in at least 25% of patients who received Unituxin/RA in Study 1 included hyponatremia, hypokalemia, and hypocalcemia. Severe (Grade 3 or 4) hypokalemia and hyponatremia occurred in 37% and 23% of patients in the Unituxin/RA group respectively compared to 2% and 4% of patients in the RA group. In a study of a related anti-GD2 antibody conducted in 12 adult patients with metastatic melanoma, 2 (13%) patients developed syndrome of inappropriate antidiuretic hormone secretion resulting in severe hyponatremia. Monitor serum electrolytes daily during therapy with Unituxin.
Atypical Hemolytic Uremic Syndrome
Hemolytic uremic syndrome in the absence of documented infection and resulting in renal insufficiency, electrolyte abnormalities, anemia, and hypertension occurred in two patients enrolled in Study 2 following receipt of the first cycle of dinutuximab. Atypical hemolytic uremic syndrome recurred following rechallenge with Unituxin in one patient. Permanently discontinue Unituxin and institute supportive management for signs of hemolytic uremic syndrome.
Embryo-Fetal Toxicity
Based on its mechanism of action, Unituxin may cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment, and for two months after the last dose of Unituxin [see Use in Specific Populations (8.1, 8.3) and Clinical Pharmacology (12.1)].

Clinical Trials Experience
Because 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 rates observed in clinical practice.
The data described below reflect exposure to Unituxin at the recommended dose and schedule in 1021 patients with high-risk neuroblastoma enrolled in an open label, randomized (Study 1) or single arm clinical trials (Study 2 and Study 3). Prior to enrollment, patients received therapy consisting of induction combination chemotherapy, maximum feasible surgical resection, myeloablative consolidation chemotherapy followed by autologous stem cell transplant, and radiation therapy to residual soft tissue disease. Patients received Unituxin in combination with granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin-2 (IL-2) and 13-cis-retinoic acid (RA). Treatment commenced within 95 days post autologous stem cell transplant in Study 1, within 210 days of autologous stem cell transplant in Study 2, and within 110 days of autologous stem cell transplant in Study 3.
Study 1
In a randomized, open label, multi-center study (Study 1), 134 patients received dinutuximab in combination with GM-CSF, IL-2 and RA (Unituxin/RA group), including 109 randomized patients and 25 patients with biopsy-proven residual disease who were non-randomly assigned to receive dinutuximab. A total of 106 randomized patients received RA alone (RA group) [see Dosage and Administration (2)and Clinical Studies (14)]. Patients had a median age at enrollment of 3.8 years (range: 0.94 to 15.3 years), and were predominantly male (60%) and White (82%). In Study 1, adverse reactions of Grade 3 or greater severity were comprehensively collected, but adverse reactions of Grade 1 or 2 severity were collected sporadically and laboratory data were not comprehensively collected.
Approximately 71% of patients in the Unituxin/RA group and 77% of patients in the RA group completed planned treatment. The most common reason for premature discontinuation of study therapy was adverse reactions in the Unituxin/RA group (19%) and progressive disease (17%) in the RA group.
The most common adverse drug reactions (≥ 25%) in the Unituxin/RA group were pain, pyrexia, thrombocytopenia, lymphopenia, infusion reactions, hypotension, hyponatremia, increased alanine aminotransferase, anemia, vomiting, diarrhea, hypokalemia, capillary leak syndrome, neutropenia, urticaria, hypoalbuminemia, increased aspartate aminotransferase, and hypocalcemia. The most common serious adverse reactions (≥ 5%) in the Unituxin/RA group were infections, infusion reactions, hypokalemia, hypotension, pain, fever, and capillary leak syndrome.
Table 5 lists the adverse reactions reported in at least 10% of patients in the Unituxin/RA group for which there was a between group difference of at least 5% (all grades) or 2% (Grade 3 or greater severity).

Study 2 and Study 3
Study 2 was a single arm, multicenter expanded access trial that enrolled patients with high-risk neuroblastoma (N=783). The reported adverse event profile of dinutuximab in Study 2 was similar to that observed in Study 1.
Study 3 was a multicenter, single arm safety study of dinutuximab in combination with GM-CSF, IL-2 and RA. In Study 3, adverse events of all CTCAE grades and laboratory data were systematically and comprehensively collected. Of 104 patients enrolled and treated in Study 3, 77% of patients completed study therapy. In general, the adverse reaction profile of dinutuximab observed in Study 3 was similar to that observed in Study 1 and Study 2. The following adverse reactions not previously reported in Study 1 were reported in at least 10% of patients in Study 3: nasal congestion (20%) and wheezing (15%). Table 7 provides the per-patient incidence of laboratory abnormalities in Study 3.

As with all therapeutic proteins, patients treated with Unituxin may develop anti-drug antibodies. In clinical studies, 52 of 284 (18%) patients from Study 2 and 13 of 103 (13%) patients from Study 3 tested positive for anti-dinutuximab binding antibodies. Neutralizing antibodies were detected in 3.6% of patients who were tested for anti-dinutuximab binding antibodies in Study 2 and Study 3. However, due to the limitations of the assay, the incidence of neutralizing antibodies may not have been reliably determined.
The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of incidence of antibodies to Unituxin with the incidences of antibodies to other products may be misleading.
Postmarketing Experience
The following adverse reactions have been identified during post-approval use of Unituxin. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
· Neurotoxicity: prolonged urinary retention, transverse myelitis, and reversible posterior leukoencephalopathy syndrome (RPLS) [see Warnings and Precautions (5.2)].
Drug Interactions
No drug-drug interaction studies have been conducted with dinutuximab.
USE IN SPECIFIC POPULATIONSPregnancy
Risk Summary
Based on its mechanism of action, Unituxin may cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no studies in pregnant women and no reproductive studies in animals to inform the drug-associated risk. Monoclonal antibodies are transported across the placenta in a linear fashion as pregnancy progresses, with the largest amount transferred during the third trimester. Advise pregnant women of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population is unknown. However, the background risk in the U.S. general population of major birth defects is 2-4% and of miscarriage is 15-20% of clinically recognized pregnancies.
Lactation
Risk Summary
There is no information available on the presence of dinutuximab in human milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production. However, human IgG is present in human milk. Because of the potential for serious adverse reactions in a breastfed infant, advise a nursing woman to discontinue breastfeeding during treatment with Unituxin.
Females and Males of Reproductive Potential
Contraception
Females
Unituxin may cause fetal harm [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception during treatment and for two months after the last dose of Unituxin.
Pediatric Use
The safety and effectiveness of Unituxin as part of multi-agent, multimodality therapy have been established in pediatric patients with high-risk neuroblastoma based on results of an open-label, randomized (1:1) trial conducted in 226 patients aged 11 months to 15 years (median age 3.8 years) (Study 1). Prior to enrollment, patients achieved at least a partial response to prior first-line therapy for high-risk neuroblastoma consisting of induction combination chemotherapy, maximum feasible surgical resection, myeloablative consolidation chemotherapy followed by autologous stem cell transplant, and received radiation therapy to residual soft tissue disease. Patients randomized to the Unituxin/13-cis-retinoic acid (RA) arm (Unituxin/RA) received up to five cycles of Unituxin in combination with alternating cycles of granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-2 (IL-2) plus RA, followed by one cycle of RA alone. Patients randomized to the RA arm received up to six cycles of RA monotherapy. Study 1 demonstrated an improvement in event-free survival and overall survival in patients in the Unituxin/RA arm compared to those in the RA arm [see Adverse Reactions (6), Clinical Pharmacology (12), and Clinical Studies (14)].
Geriatric Use
The safety and effectiveness of Unituxin in geriatric patients have not been established.
Renal Impairment
Unituxin has not been studied in patients with renal impairment.
Hepatic Impairment
Unituxin has not been studied in patients with hepatic impairment.
Unituxin Description
Unituxin (dinutuximab) is a chimeric monoclonal antibody composed of murine variable heavy and light chain regions and the human constant region for the heavy chain IgG1 and light chain kappa. Unituxin binds to the glycolipid disialoganglioside (GD2). Dinutuximab is produced in the murine myeloma cell line, SP2/0.
Unituxin is a sterile, preservative-free, clear/colorless to slightly opalescent solution for intravenous infusion. Unituxin is supplied in single-use vials of 17.5 mg/5 mL. Each vial contains 3.5 mg/mL of dinutuximab, histidine (20 mM), polysorbate 20 (0.05%), sodium chloride (150 mM), and water for injection; hydrochloric acid is added to adjust pH to 6.8.
Unituxin - Clinical PharmacologyMechanism of Action
Dinutuximab binds to the glycolipid GD2. This glycolipid is expressed on neuroblastoma cells and on normal cells of neuroectodermal origin, including the central nervous system and peripheral nerves. Dinutuximab binds to cell surface GD2 and induces cell lysis of GD2-expressing cells through antibody-dependent cell-mediated cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC).
Pharmacokinetics
The pharmacokinetics of dinutuximab was evaluated by a population pharmacokinetic analysis in a clinical study of Unituxin in combination with GM-CSF, IL-2, and RA. In this study, 27 children with high-risk neuroblastoma (age: 3.9±1.9 years) received up to 5 cycles of Unituxin at 17.5 mg/m2/day as an intravenous infusion over 10 to 20 hours for 4 consecutive days every 28 days. The observed maximum plasma dinutuximab concentration (Cmax) was 11.5 mcg/mL [20%, coefficient of variation (CV)]. The mean volume of distribution at steady state (Vdss) was 5.4 L (28%). The clearance was 0.21 L/day (62%) and increased with body size. The terminal half-life was 10 days (56%).
No formal pharmacokinetic studies were conducted in patients with renal or hepatic impairment.
Nonclinical ToxicologyCarcinogenesis, Mutagenesis, Impairment of Fertility
No animal studies have been conducted to evaluate the carcinogenic or mutagenic potential of dinutuximab.
Dedicated studies examining the effects of dinutuximab on fertility in animals have not been conducted. No clear effects on reproductive organs were observed in general toxicology studies conducted in rats.
Animal Toxicology and/or Pharmacology
Non-clinical studies suggest that dinutuximab-induced neuropathic pain is mediated by binding of the antibody to the GD2 antigen located on the surface of peripheral nerve fibers and myelin and subsequent induction of CDC and ADCC activity.
Clinical Studies
The safety and effectiveness of Unituxin was evaluated in a randomized, open-label, multicenter trial conducted in pediatric patients with high-risk neuroblastoma (Study 1). All patients had received prior therapy consisting of induction combination chemotherapy, maximum feasible surgical resection, myeloablative consolidation chemotherapy followed by autologous stem cell transplant, and radiation therapy to residual soft tissue disease. Patients were randomized between Day 50 and Day 77 post-autologous stem cell transplantation.
Patients were required to have achieved at least a partial response prior to autologous stem cell transplantation, have no evidence of disease progression following completion of front-line multi-modality therapy, have adequate pulmonary function (no dyspnea at rest and peripheral arterial oxygen saturation of at least 94% on room air), adequate hepatic function (total bilirubin < 1.5 × the upper limit of normal and ALT < 5 × the upper limit of normal), adequate cardiac function (shortening fraction of > 30% by echocardiogram, or if shortening fraction abnormal, ejection fraction of 55% by gated radionuclide study), and adequate renal function (glomerular filtration rate at least 70 mL/min/1.73 m2). Patients with systemic infections or a requirement for concomitant systemic corticosteroids or immunosuppressant usage were not eligible for enrollment.
Patients randomized to the Unituxin/RA arm received up to five cycles of dinutuximab (clinical trials material) in combination with granulocyte-macrophage colony-stimulating factor (GM-CSF) (Table 8) or interleukin-2 (IL-2) (Table 9) plus 13-cis-retinoic acid (RA), followed by one cycle of RA alone. Patients randomized to the RA arm received six cycles of RA. Dinutuximab was administered at a dose of 17.5 mg/m2/day (equivalent to 25 mg/m2/day of clinical trials material) on four consecutive days. Patients in both treatment arms received six cycles of RA at a dose of 160 mg/m2/day orally (for patients weighing more than 12 kg) or 5.33 mg/kg/day (for patients weighing less than or equal to 12 kg) in two divided doses for 14 consecutive days.
A total of 226 patients were randomized, 113 patients to each arm. In general, demographic and baseline tumor characteristics were similar across study arms. Across the study population, 60% were male, the median age was 3.8 years and 3% of patients were less than 1.5 years, 82% were White and 7% were Black. The majority (80%) of patients had International Neuroblastoma Staging System Stage 4 disease. Thirty-five percent of patients had a complete response, 43% had a very good partial response, and 23% had a partial response to therapy received prior to autologous stem cell transplant. Forty-six percent of patients had neuroblastoma that was not MYCN-amplified, 36% had tumors with known MYCN-amplification, and MYCN status was unknown or missing in 19% of patients. Forty-three percent of patients had hyperdiploid tumors, 36% had diploid tumors, and DNA ploidy status was unknown or missing in 21% of patients.
The major efficacy outcome measure was investigator-assessed event-free survival (EFS), defined as the time from randomization to the first occurrence of relapse, progressive disease, secondary malignancy, or death. Overall survival (OS) was also evaluated. After observing a numerical improvement in EFS based on the seventh interim analysis, the Data Monitoring Committee recommended termination of accrual. Efficacy results are shown in Table 10.
