项目摘要
PROJECT SUMMARY
A solid Consortium project should contribute a unique and compelling approach to neuroblastoma
and supply tools or components that enable other members of the Consortium to make their best
work even better. The project detailed here commences with the selection and careful
characterization of a dozen fully human antibodies to Glypican-2, the most promising antigen in
neuroblastoma, from a pre-existing hybridoma stock. These antibodies, along with their full
sequences, binding affinities, cellular internalization, epitope, and (where possible) crystal structures,
will be made available to Consortium members within the first year for use in their modality of choice.
This project will explore their utility as components in double bispecific antibody therapy: this double
bispecific approach targets two cancer antigens and two T cell receptors simultaneously, inducing T
cell activation and co-activation only in the presence of cancer cells expressing both antigens. The
double targeting strategy should allow for a much higher level of selective engagement and killing
than has heretofore been possible with therapies that target only a single cancer antigen, and should
it prove effective in neuroblastoma the approach is likely to have utility in a wide variety of cancers.
One historical weakness for the development of immuno-oncology approaches such as this one is
that the animal models have had very little predictive value. For this reason, the best of the
humanized mouse models, “MISTRG” mice, will be used both for the development of these molecules
and for testing the other consortium members’ approaches, where they could be useful. CIVO multi-
needle array technology will be employed to simplify the combinatorial challenge associated with
testing pairs of bispecific molecules; this technology will also be open for use collaboratively with the
other Consortium members. In short, the proposal provides the Consortium with human antibodies
against a validated neuroblastoma target, access to the current state-of-the-art in humanized mice, a
CIVO multi-needle array device to facilitate testing therapeutics, and a double bispecific antibody
therapeutic approach that promises a high level of T cell killing and selectivity and a likely broad
applicability beyond neuroblastoma.
项目总结
一个坚实的联合体项目应该为神经母细胞瘤提供一种独特而引人注目的方法
并提供工具或组件,使联盟的其他成员能够尽其所能
工作得更好。这里详细介绍的项目是从选择和仔细开始的
十几种针对Glypcan-2的全人抗体的鉴定
神经母细胞瘤,来自先前存在的杂交瘤种群。这些抗体,连同它们的完整
序列、结合亲和力、细胞内化、表位和(可能的)晶体结构,
将在第一年内提供给联盟成员,供他们选择的模式使用。
该项目将探索它们作为双双特异性抗体治疗组件的用途:这一双
双特异性方法同时靶向两个癌症抗原和两个T细胞受体,诱导T细胞
只有在表达这两种抗原的癌细胞存在的情况下,细胞才能激活和共激活。这个
双重目标战略应该允许更高水平的选择性交战和杀戮
比到目前为止只针对单一癌症抗原的治疗方法更有可能,而且应该
它被证明对神经母细胞瘤有效,这种方法很可能在各种癌症中有用。
像这样的免疫肿瘤学方法发展的一个历史弱点是
动物模型几乎没有预测价值。出于这个原因,最好的
人源化的小鼠模型“MISTRG”小鼠将被用于这些分子的开发
并用于测试其他财团成员的方法,这些方法可能会有用。Civo MULTI-
将采用针阵列技术来简化与以下方面相关的组合挑战
测试双功能分子对;这项技术也将开放与
其他财团成员。简而言之,该提案为该联盟提供了人类抗体
与经过验证的神经母细胞瘤靶点相比,获得人源化小鼠的当前最先进技术,
Civo多针阵列装置,便于检测治疗药物,以及双特异性抗体
一种治疗方法,承诺高水平的T细胞杀伤和选择性,并可能广泛
神经母细胞瘤以外的适用性。
