Defence Therapeutics Inc.<\/a>\u00a0has announced a significant milestone in its radio-immuno-conjugates project.<\/h2>\n

The\u00a0Canadian Nuclear Research Initiative Health (CNRI-H) Program<\/a>\u00a0application by Defence Therapeutics has been approved by the Canadian Nuclear Laboratories (CNL), facilitating the acceleration of their innovative research.<\/p>\n

Focus of the CNRI-H project<\/h3>\n

The CNRI-H project by Defence Therapeutics will concentrate on the synthesis and evaluation of novel constructs, specifically variations of\u00a0111<\/sup>In-AccuTOX\u00ae-Trastuzumab.<\/p>\n

The primary aim is to establish that the AccuTOX\u00ae moiety is a crucial enhancement to conventional\u00a0111<\/sup>In-Trastuzumab constructs.<\/p>\n

This modification is designed to avoid endosome entrapment and ensure nuclear localisation, where\u00a0111<\/sup>In will emit Auger Electrons (AEs) to\u00a0destroy cancer cells<\/a>. Additionally, AccuTOX\u00ae will unleash its immune-boosting properties, creating a synergistic effect.<\/p>\n

Development and testing<\/h3>\n

Selected AccuTOX\u00ae constructs will be assessed based on their stability, solubility, and biochemical properties.<\/p>\n

These constructs will be conjugated to the trastuzumab antibody, radiolabeled with\u00a0111<\/sup>In, and characterised both in vitro and in vivo to determine their effectiveness in targeting and killing cancer cells.<\/p>\n

The ultimate goal is to identify a biologically active\u00a0111<\/sup>In-AccuTOX\u00ae-Trastuzumab molecule that demonstrates higher potency against solid tumours resistant to current HER2-targeting therapies, such as therapeutic antibodies (e.g., trastuzumab) and antibody-drug conjugates (e.g., Kadcyla\u00ae).<\/p>\n

The collaborative project aims to:<\/p>\n
