We believe this supports the potential for deep and durable clinical responses that can ultimately help extend overall survival,” said Dr Karl Peggs, Chief Medical Officer of Achilles Therapeutics. “The encouraging safety and tolerability profile, coupled with reduced dose lymphodepletion and IL-2 continues to support expanded application to a broader patient population. We look forward to sharing additional updated safety, activity, and translational science details at ESMO IO.” Data on 14 heavily pre-treated patients (eight patients from CHIRON with advanced NSCLC and six patients from THETIS with recurrent melanoma) that received cNeT as monotherapy and had completed at least one post-treatment scan six weeks following dosing by the abstract cut-off date will be presented. Safety and tolerability observations of cNeT compare favorably to standard tumor infiltrating lymphocytes (TIL) due to less IL-2 related toxicity. Lymphopenia and neutropenia were the most common adverse events, which are principally associated with the conditioning regimen, and no dose limiting high-grade toxicities associated with IL-2 were reported. The best clinical response was a partial response (ongoing at week 33) in a NSCLC patient that showed an investigator-reported 57% total tumor reduction at week 24. Translational science analysis shows that peak expansion of cytokine-secreting cNeT at day 21 was coincident with signs of systemic immune activation including increased serum IL-6. Stable disease was observed in five NSCLC patients through week 12, with two patients remaining stable beyond weeks 15 and 26. Further characterization of cNeT using single cell RNA and TCR-seq suggests that cNeT products are polyclonal, with reactive T cell clusters bearing signatures of T cell proliferation, cytokine secretion, and tissue migration.

About Achilles TherapeuticsAchilles is a clinical-stage biopharmaceutical company developing AI-Powered precision T cell therapies targeting clonal neoantigens: protein markers unique to the individual that are expressed on the surface of every cancer cell. The Company has two ongoing Phase I/IIa trials, the CHIRON trial in patients with advanced non-small cell lung cancer (NSCLC) and the THETIS trial in patients with recurrent or metastatic melanoma. Achilles uses DNA sequencing data from each patient, together with its proprietary PELEUS™ bioinformatics platform, to identify clonal neoantigens specific to that patient, and then develop precision T cell-based product candidates specifically targeting those clonal neoantigens. About the CHIRON and THETIS Clinical TrialsCHIRON is an open-label, multi-center Phase I/IIa clinical trial evaluating the safety, tolerability, and clinical activity of cNeT therapy as a single dose in adult patients with advanced metastatic NSCLC. THETIS is an open-label, multi-center Phase I/IIa clinical trial evaluating the safety, tolerability, and clinical efficacy of cNeT therapy as a single dose in patients with recurrent or metastatic malignant melanoma as monotherapy and in combination with a PD-1 inhibitor.
