美国FDA3月10日宣布批准Unituxin (dinutuximab)作为高风险神经母细胞瘤患儿综合治疗方案(包括手术、化疗、放射治疗)中的一线治疗药物。 神经母细胞瘤是未成熟神经细胞演变成的一种罕见肿瘤,通常始发于肾上腺,也可能发作于腹部、胸部或临近脊柱的神经组织,常见于小于5岁的儿童。根据美国国立癌症研究所的统计,神经母细胞瘤在儿童中的发病率为1/100000,在男孩中相对常见一些。美国每年

美国FDA3月10日宣布批准Unituxin (dinutuximab)作为高风险神经母细胞瘤患儿综合治疗方案(包括手术、化疗、放射治疗)中的一线治疗药物。

神经母细胞瘤是未成熟神经细胞演变成的一种罕见肿瘤,通常始发于肾上腺,也可能发作于腹部、胸部或临近脊柱的神经组织,常见于小于5岁的儿童。根据美国国立癌症研究所的统计,神经母细胞瘤在儿童中的发病率为1/100000,在男孩中相对常见一些。美国每年有新确诊神经母细胞瘤患者约650例。如果给予积极治疗,这类患者中40%~50%有长期生存的机会。

Unituxin是一种抗体药物,可以结合在神经母细胞瘤细胞的表面,此次被批准为神经母细胞瘤综合治疗方案中的一线药物,适用于对既往综合治疗方案至少产生部分应答的神经母细胞瘤患者。

美国FDA药品评价和研究中心血液疾病和肿瘤产品办公室主任Richard Pazdur博士表示:“Unituxin 是FDA批准的首个特异性针对高风险神经母细胞瘤患者的治疗药物,可在一定程度上满足高风险神经母细胞瘤儿童延长存活期的需求”。

Unituxin的安全性和疗效在一项涉及226例高风险神经母细胞瘤患儿的临床试验中得到证实。 这些患儿的肿瘤在接受了骨髓移植、多药化疗和手术后缩小或消失。受试者随机接受维甲酸、异维A酸、Unituxin+IL-2+GM-CSF。治疗后3年, Unituxin联合用药组中63%的患者存活和无肿瘤生长或复发,异维甲酸组为46%。在最新的生存分析中,Unituxin联合用药组存活比例为73%,异维甲酸组为58%。

Unituxin的药品标签中附有黑框警告,提示患者和卫生保健人员Unituxi会刺激神经细胞,从而导致严重疼痛并需要使用静脉麻醉药品治疗,Unituxi还可能会发生导致神经损伤和危及生命的注射反应,包括上呼吸道肿胀、呼吸困难、低血压。Unituxin的其他严重副作用包括感染、眼科问题、电解质异常和骨髓抑制。

Unituxin最常见的副作用包括严重疼痛、发热、低血小板计数、输注反应、低血压、低钠血症、肝酶升高、贫血、呕吐、腹泻、低钾血症、毛细血管渗漏综合征、中性粒细胞减少和淋巴细胞减少、荨麻疹和低钙血症。

FDA曾授予Unituxin优先审评和孤儿药资格。与此同时, FDA还给United Therapeutics公司颁发了“罕见儿科疾病药物优先审评”的证书,这样以来,United公司下面提交的一个原本不符合优先审评条件的儿科新药申请将可获得优先审评资格。这是FDA自实施罕见儿科疾病优先审评证书项目以来颁发出的第2张证书,旨在鼓励针对某些罕见儿科疾病的药物开发。

JAMA:研究表明ATRX突变与神经母细胞瘤相关

近日,《美国医学会杂志》JAMA上的一项研究报告指出,基因ATRX的某些突变与儿童和青壮年在被诊断患有晚期神经母细胞瘤,一种在神经系统的某些部位生长的癌症时的年龄有关。 神经母细胞瘤是儿童中最常见的颅外(头颅外)实体肿瘤,它占了儿童中所有因癌症死亡的15%。根据文章的背景资料:“半数的(50%)的神经母细胞瘤会表现为转移性病变;以目前的治疗方法,诊断年龄被证明是治疗结果的最强有力的预测指标之

NAT GENET:儿童侵袭性神经母细胞瘤预后与ARID1A和ARID1B基因有关

  来自约翰霍普金斯大学Kimmel癌症中心和费城儿童医院(CHOP)的科学家们在对74个儿童神经母细胞瘤进行全基因组测序后,发现ARID1A和ARID1B两个基因发生改变的患儿相比无此基因改变的患儿生存期缩短了四分之三。这一发现有可能最终导致早期确认患有侵袭性神经母细胞瘤的儿童,他们或许需要接受其他的治疗。相关论文发表在12月2日的《自然遗传学》(Nature Genetics)杂志上

STM:ALK抑制剂TAE-684能使ALK突变型神经母细胞瘤完全消退

最近发现在10%的散发神经母细胞瘤和大多数家族性神经母细胞瘤患者中,存在激活的间变性淋巴瘤激酶(ALK)基因突变,。然而,在肿瘤发生中ALK突变的作用仍然是难以捉摸的。 7月4日,Sci Transl Med杂志报道,有针对性的表达最常见和最具侵袭性的突变类型ALK-F1174L可诱发小鼠的神经母细胞瘤。这些诱发的小鼠肿瘤在形态,转移模式,基因表达等方面均与人类神经母细胞瘤相似。并且,小鼠肿瘤同

PBC:索拉菲尼可降低神经母细胞瘤生长速度

视网膜母细胞瘤高危患儿亟需得到更有效的治疗方法。由于临床前研究已经证明,阻断血管再生的药物可以抑制神经母细胞瘤生长。因此来自芝加哥大学的Nisha C. Kakodkar博士等人提出一种假设,即靶点为神经母细胞瘤细胞和肿瘤血管生成的药物可能具有抑制肿瘤的活性。他们对一种多激酶抑制剂-索拉菲尼对神经母细胞瘤细胞增殖及信号传导的影响进行了试验,试验对象为皮下异种移植人类神经母细胞瘤或原位肾上腺肿瘤的小

PNAS:科学家发现神经母细胞瘤患者的耐药机制

尽管经过多年的精心研究,但神经母细胞瘤,成人中一种最常见和致命的脑癌仍继续有针对性地克服抑制肿瘤生长的治疗。 生物学家和肿瘤学家们早就知道,至少50%的胶质母细胞瘤患者存在一种称为表皮生长因子受体的蛋白质EGFR的改变。 然而,胶质母细胞瘤患者要么会遇到治疗的前期阻力,要么会对阻止蛋白质功能的抑制剂迅速产生耐药性,这提示表明还有另一个信号通路在神经母细胞瘤中发挥作用。 近日,美国加州大学圣迭戈
