As the field evolves, scientists are increasingly exploring payloads designed to modulate disease-specific biology, creating opportunities to improve precision, tolerability, and therapeutic outcomes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this poster, Sygnature Discovery scientists discuss emerging principles for developing next-generation ADC payloads. Drawing on medicinal chemistry and mechanistic pharmacology expertise, the poster explores how properties such as potency, LogD, pKa, permeability, and stability can be optimized to improve efficacy while reducing systemic toxicity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"#download\">Download the poster<\/a> to explore the latest thinking around ADC payload discovery and the evolving guidelines shaping the future of targeted drug conjugates.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-blue-600-color has-text-color has-link-color has-text-xl-font-size wp-elements-1\" style=\"margin-top:var(--wp--preset--spacing--40);margin-bottom:var(--wp--preset--spacing--40)\"><strong>Developing Guidelines for Next-Generation ADC Payloads<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Historically, ADC development has relied on a relatively small number of highly potent cytotoxic payloads. As the industry moves towards targeted payloads that act on disease-specific biology, new design considerations are emerging.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Traditional medicinal chemistry principles developed for oral small molecules do not always translate directly to ADC payload optimization. This poster explores key attributes that may help guide the design of next-generation ADC payloads, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Potency requirements for effective intracellular target engagement<\/li>\n\n\n\n<li>Physicochemical properties that support lysosomal escape and target engagement<\/li>\n\n\n\n<li>Strategies to reduce systemic exposure through engineered metabolic clearance<\/li>\n\n\n\n<li>The role of permeability and efflux in controlling bystander effects<\/li>\n\n\n\n<li>Approaches to improving ADC developability and therapeutic window<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading has-blue-600-color has-text-color has-link-color has-text-xl-font-size wp-elements-2\" style=\"margin-top:var(--wp--preset--spacing--40);margin-bottom:var(--wp--preset--spacing--40)\"><strong>Why Mechanistic Understanding Matters<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">As payloads become increasingly targeted and mechanism-driven, understanding the relationship between payload design, target engagement, and biological response becomes critical.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The poster explores key factors that influence ADC success, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Timing of downstream biological responses<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Antigen binding and cellular internalization<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lysosomal processing and payload release<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Intracellular target engagement<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Pharmacokinetic and pharmacodynamic relationships<\/li>\n<\/ul>\n\n\n\n<h2 id=\"download\" class=\"wp-block-heading has-blue-600-color has-text-color has-link-color has-text-xl-font-size wp-elements-3\" style=\"margin-top:var(--wp--preset--spacing--40);margin-bottom:var(--wp--preset--spacing--40)\"><strong>Download the Poster<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Download the full conference poster to explore:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Emerging design principles for next-generation ADC payloads<\/li>\n\n\n\n<li>Suggested physicochemical property ranges for targeted payloads<\/li>\n\n\n\n<li>The relationship between payload properties and therapeutic outcomes<\/li>\n\n\n\n<li>Mechanistic approaches to de-risking ADC development<\/li>\n\n\n\n<li>Strategies to reduce systemic toxicity while maintaining efficacy<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This work highlights how a deeper understanding of payload properties, linker design, and target biology is helping redefine ADC discovery and establish new guidelines for the development of next-generation therapeutics.<\/p>\n\n\n\n<p class=\"has-blue-600-color has-text-color has-link-color has-text-xl-font-size wp-elements-4 wp-block-paragraph\" style=\"margin-top:var(--wp--preset--spacing--40);margin-bottom:var(--wp--preset--spacing--40)\"><strong><a href=\"https:\/\/pubs.acs.org\/bcches\/article-abstract\/37\/9\/1798\/5287599\/Beyond-Cytotoxic-Payloads-for-Antibody-Drug?redirectedFrom=fulltext\">View the publication relating to this poster here<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"featured_media":19549,"template":"","category":[1],"class_list":["post-19326","poster","type-poster","status-publish","has-post-thumbnail","hentry","category-uncategorized"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 -
