Provided interim Phase I/IIa update on clonal neoantigen reactive T cells in advanced NSCLC and melanoma
Improved VELOS™ manufacturing process delivering higher cNeT doses
Protocols updated to evaluate the benefit of enhanced host conditioning, with further data expected in 2H 2024
Strong cash position of $131.5 million supports operations through 2025

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

2023 and Year-to-Date 2024 Corporate Highlights

Publication in Nature Cancer from researchers affiliated with Achilles and the DECOD-Ag consortium outlined the vast potential of neoantigen immunogenicity prediction
neoRanker™, a new AI-enabled neoantigen immunogenicity ranking module of PELEUS™, outperformed current AI and non-AI state-of-the-art methods for neoantigen immunogenicity prediction
U.S. patent 11,634,773 granted covering treatment with an immunotherapy that targets a neoantigen predicted to be presented by a human leukocyte antigen (HLA) allele that has not been lost in a tumor, where loss of HLA alleles is determined using a proprietary sequence-based method
Regained compliance with the minimum bid price requirement of Nasdaq Listing Rule 5450(a)(1) on March 1, 2024, as confirmed by a written notice received from the Listing Qualifications Department of The Nasdaq Stock Market on March 4, 2024

Financial Highlights

Cash and cash equivalents: Cash and cash equivalents were $131.5 million as of December 31, 2023, as compared to $173.3 million as of December 31, 2022. The Company anticipates that its cash and cash equivalents are sufficient to fund its planned operations through 2025.
Research and development (R&D) expenses: R&D expenses were $15.9 million for the fourth quarter ended December 31, 2023, a decrease of $3.0 million compared to $18.9 million for the fourth quarter ended December 31, 2022. R&D expenses were $58.2 million for the year ended December 31, 2023, an increase of $0.9 million compared to $57.3 million for the year ended December 31, 2022. The increase was primarily driven by an increased focus on the ongoing clinical trials.
General and administrative (G&A) expenses: G&A expenses were $3.6 million for the fourth quarter ended December 31, 2023, a decrease of $0.4 million compared to $4.0 million for December 31, 2022. G&A expenses were $17.1 million for the year ended December 31, 2023, a decrease of $4.0 million compared to the $21.1 million for the year ended December 31, 2022. This decrease was primarily driven by lower personnel costs and lower legal and professional fees.
Net loss: Net loss for the fourth quarter ended December 31, 2023 was $18.6 million or $0.46 per share compared to $24.1 million or $0.61 per share for the fourth quarter ended December 31, 2022.

2024 Focus and Upcoming Events

Clinical Data: Report clinical activity and translational science data from patients in CHIRON and THETIS Cohort C, evaluating the benefit of enhanced host conditioning, with a meaningful data update expected in 2H 2024
Translational Science: Leverage the Company’s world-class translational science platform to define the features associated with clinical response and to pursue rational design of the final cNeT product
Clinical Activity: Drive additional confirmed responses in CHIRON and THETIS patients on cNeT therapy by delivering higher cNeT doses with enhanced host conditioning
Manufacturing Development: Continue VELOS™ and PELEUS™ development to optimize cNeT dose and functionality

About Achilles Therapeutics

Achilles 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.
