MULTIDOMAIN BIOTAGS FOR CANCER DETECTION, DIAGNOSIS AND THERAPY AND METHODS OF THEIR USE PRIORITY STATEMENT
(FR)
BIOMARQUEURS À DOMAINES MULTIPLES POUR LA DÉTECTION, LE DIAGNOSTIC ET LA THÉRAPIE DU CANCER
Abstract:
(EN)
A biotag for targeting a cancer biomarker is provided. The biotag may include a cancer biomarker binding domain, an internalization domain, an endosomal escape domain, a lysosomal escape domain, a reporter binding domain, and a reporter, wherein the reporter is a diagnostic agent. The cancer biomarker can be ERBB 1-4, EGFRvlH or Transferrin Receptor (TfR). The binding domain can be an scFv, an sdFv, a CDR or an SDR modified CDR. The reporter binding domain is a metal binding domain, which may be chelated to a metal nanoparticle tag. The metal nanoparticle tag is a noble metal, a superparamagnetic metal, a core-shell nanoparticle, or a fluorescent agent. A targeted contrast composition for use with a diagnostic imaging technique is provided, which includes a contrast agent and a biotag for targeting a cancer biomarker.
(FR)
La présente invention concerne, dans un mode de réalisation, un biomarqueur destiné à cibler un indicateur biologique du cancer. Le biomarqueur peut comprendre un domaine de liaison à un indicateur biologique du cancer, un domaine d'internalisation, un domaine de fuite endosomale, en domaine de fuite lysosomale, un domaine de liaison au rapporteur, et un rapporteur, le rapporteur étant un agent diagnostic. Dans certains aspects, l'indicateur biologique du cancer est ERBB 1-4, EGFRvIII ou le récepteur de la transferrine (TfR). Dans d'autres aspects, le domaine de liaison est un scFv, un sdFv, un CDR ou un CDR modifié par un SDR. Dans certains aspects, le domaine de liaison au rapporteur est un domaine de liaison au métal, qui peut être chélaté à un marqueur nanoparticulaire métallique. Dans certains aspects, le marqueur nanoparticulaire métallique est un métal noble, un métal superparamagnétique, une nanoparticule cœur-enveloppe, ou un agent fluorescent. Dans un autre mode de réalisation, la présente invention concerne une composition de contraste ciblée destinée à être utilisée avec une technique d'imagerie diagnostique, qui comprend un agent de contraste et un biomarqueur destiné à cibler un indicateur biologique du cancer.
