LONDON, April 04, 2024 (GLOBE NEWSWIRE) -- Achilles Therapeutics plc (NASDAQ: ACHL), a clinical-stage biopharmaceutical company developing AI-powered precision T cell therapies targeting clonal neoantigens to treat solid tumors, today announced its financial results for the fourth quarter and year-ended December 31, 2023, and recent business highlights.

“In 2023, we made important progress on the optimization of our VELOS™ manufacturing process with a significant improvement in cNeT doses delivered and are developing our understanding of the relationship between host conditioning and the engraftment of infused cNeT. We recently shared updated safety, tolerability and translational science data from checkpoint refractory patients that continue to be encouraging and reveal important mechanistic learnings about the factors driving durable T cell engraftment and the impact of immune evasion mechanisms at an antigen level. These learnings will inform the development of cNeT and related neoantigen vaccine and TCR-T therapies,” said Dr Iraj Ali, Chief Executive Officer of Achilles Therapeutics. “Looking ahead to 2024, we will evaluate cNeT persistence and clinical activity in patients with enhanced host conditioning, and we plan to report a meaningful data update in the second half of 2024. Our financial position remains strong with more than $131 million in cash, which supports operations through 2025, including the completion of the ongoing Phase I/IIa trials.”

2023 and Year-to-Date 2024 Clinical Highlights

  • Provided an interim Phase I/IIa update on clonal neoantigen reactive T cells in advanced NSCLC and melanoma from 18 new patients, highlighting improved doses from the VELOS™ manufacturing process and a favorable tolerability profile

  • The VELOS™ manufacturing process delivered ~10-fold improvement in the median cNeT dose (172 million) across the 18 patients in the update, with 10 products over 100 million cNeT and five over one billion cNeT

  • First patients dosed in CHIRON and THETIS with enhanced host conditioning to evaluate the benefit of increased lymphodepletion intensity and Il-2 dosing aligned to standard TIL therapy, with additional meaningful data expected in the fourth quarter of 2024

  • Continued development and improvements of the PELEUS™ clonal neoantigen prediction platform
