Akari Therapeutics plc has announced the initiation of IND-enabling studies for its lead antibody-drug conjugate $(ADC)$ candidate, AKTX-101, which targets the Trop2 receptor on cancer cells using a proprietary linker and a novel PH1 payload. The PH1 payload is designed to disrupt the spliceosome and has demonstrated a unique preclinical efficacy and safety profile. Results from preclinical studies, including data showing that a Trastuzumab PH1 combination with anti-PD1 produced a statistically significantly higher rate of complete responses compared to Kadcyla® + anti-PD1 (74% vs 42%, p<0.05), were recently presented at the 40th Annual SITC Meeting. Additional immune mechanism-of-action data for the PH1 payload were also presented at this conference. Akari plans to advance AKTX-101 into clinical trials in the near future and will host a webcast to discuss the presented data on November 18, 2025.
