NBTXR3 nanoparticles\u2019 characteristics, size, charge and shape, allow for efficient interaction with biological entities, cell membrane binding and cellular uptake. The nanoparticles were shown to form clusters at the subcellular level in tumor models. Of most importance, we show NBTXR3 intratumor bioavailability with dispersion of nanoparticles in the three dimensions and persistence within the tumor structure, supporting the use of NBTXR3 as effective antitumor therapeutic agent. Antitumor activity of NBTXR3 showed marked advantage in terms of survival, tumor specific growth delay and local control in A673 and HT1080 human tumor models. Changing radiotherapy benefit-risk ratio is challenging. These data are supportive for the first clinical development of hafnium oxide nanoparticles, with an on\/off mode of action through successive fractions of radiation therapy using current equipment available in hospitals.[\/az_box_icons][vc_empty_space height=&#8221;60px&#8221; responsive_lg=&#8221;hidden&#8221; responsive_md=&#8221;hidden&#8221;][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]<\/p>\n","protected":false},"featured_media":0,"menu_order":0,"template":"","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"_wds_title":"","_wds_metadesc":"","_wds_focus-keywords":"","_wds_meta-robots-adv":"","_wds_meta-robots-noindex":false,"_wds_meta-robots-nofollow":false,"_wds_meta-robots-index":false,"_wds_meta-robots-follow":false,"_wds_autolinks-exclude":false,"_wds_canonical":"","_wds_opengraph":[],"_wds_twitter":[],"wds_primary_resource_type":0,"wds_primary_data_type":0,"wds_primary_indication":0,"wds_primary_platform_type":0,"footnotes":""},"resource_type":[31],"data_type":[29],"indication":[],"platform_type":[36],"class_list":["post-1914","resource","type-resource","status-publish","hentry","resource_type-abstracts","data_type-pre-clinical","platform_type-nbtxr3"],"acf":[],"_links":{"self":[{"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/resource\/1914","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/resource"}],"about":[{"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/types\/resource"}],"version-history":[{"count":0,"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/resource\/1914\/revisions"}],"wp:attachment":[{"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/media?parent=1914"}],"wp:term":[{"taxonomy":"resource_type","embeddable":true,"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/resource_type?post=1914"},{"taxonomy":"data_type","embeddable":true,"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/data_type?post=1914"},{"taxonomy":"indication","embeddable":true,"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/indication?post=1914"},{"taxonomy":"platform_type","embeddable":true,"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/platform_type?post=1914"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
