Akari Therapeutics’ Accepted Abstract Showcasing its Novel Splicing-Targeted ADC Payload Driving Immune Activation Now Available

Core Insights - Akari Therapeutics is presenting data on its novel antibody drug conjugate (ADC) payload, PH1, at the 40th Annual Society for Immunotherapy of Cancer (SITC) Meeting, highlighting its immune mechanism-of-action and potential in oncology [1][2] Company Overview - Akari Therapeutics is focused on developing next-generation spliceosome payload ADCs, with its lead candidate, AKTX-101, targeting the Trop2 receptor on cancer cells [5][6] - The PH1 payload is designed to disrupt RNA splicing within cancer cells, showing preclinical efficacy in inducing cancer cell death and activating immune cells [5][6] Research Findings - The abstract presented at SITC indicates that the PH1 ADC, in combination with anti-PD-1, resulted in a higher rate of complete tumor regressions compared to a first-in-class ADC with a microtubule inhibitor payload [2] - The immune response stimulated by the PH1 ADC is attributed to neoantigen activation, which enhances the activity of antigen-presenting cells, B, and T-cells [2] - Notably, the combination of PH1 ADC and anti-PD-1 expanded the population of gamma-delta T cells, which are effective in tumor killing [2] Presentation Details - The oral and poster presentations will take place on November 7 and 9, 2025, at the Gaylord National Resort and Convention Center, with specific times and locations provided for attendees [3][4]
