LONDON, May 10, 2023 (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 first quarter ended March 31, 2023, and recent business highlights.

“We continue to make progress in our ongoing Phase I/IIa clinical trials evaluating our clonal neoantigen-reactive T cell (cNeT) therapy for the treatment of advanced NSCLC (CHIRON) and metastatic malignant melanoma (THETIS). Additionally, we continue to further develop PELEUS™, our patented AI-driven bioinformatics platform, that uses multi-region sequencing analysis to provide what we believe is the best method to accurately identify clonal neoantigens,” said Dr Iraj Ali, Chief Executive Officer of Achilles Therapeutics. “We are excited about the new AI immunogenicity prediction capability of the PELEUS™ platform and are very pleased with the recent grants of a US patent and MHRA Innovation Passport. We look forward to sharing more about the PELEUS™ platform at an upcoming scientific meeting and reporting additional clinical and translational science data in the fourth quarter of this year, which builds on the encouraging clinical results observed so far.”

Business Highlights

  • Announced that the new neoantigen immunogenicity prediction application of the PELEUS™ platform can uniquely identify the most potent clonal neoantigens for personalized cancer therapies, supporting potential implementation into the Company’s ongoing TIL-based clinical programs in advanced non-small cell lung cancer (NSCLC) and melanoma, and into other modalities including clonal neoantigen cancer vaccines
  • US patent number 11,634,773 granted covering the treatment of patients with an immunotherapy targeting neoantigens based on tumor HLA status
  • Innovation Passport granted for the treatment of NSCLC under the Innovative Licensing and Access Pathway (ILAP) by the Medicines and Healthcare products Regulatory Agency (MHRA), the regulatory body of the United Kingdom (UK), which aims to accelerate time to market and facilitate patient access to medicines in the UK for life-threatening or seriously debilitating conditions by providing the opportunity for enhanced regulatory and other stakeholder input during development

Financial Highlights

  • Cash and cash equivalents: Cash and cash equivalents were $158.5 million as of March 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 into the middle of 2025.
  • Research and development (R&D) expenses: R&D expenses were $13.9 million for the first quarter ended March 31, 2023, an increase of $0.9 million compared to $13.0 million for the first quarter ended March 31, 2022. The increase was primarily driven by increased activity related to our ongoing clinical trials, as well as spend associated with expansion of our manufacturing capacity and enhancements to PELEUS™ and VELOS™.
  • General and administrative (G&A) expenses: G&A expenses were $4.7 million for the first quarter ended March 31, 2023, a decrease of $1.3 million compared to $6.0 million for the first quarter ended March 31, 2022. This decrease was primarily driven by lower personnel costs.
  • Net loss: Net loss for the first quarter ended March 31, 2023 was $17.5 million or $0.44 per share compared to $17.4 million or $0.45 per share for the first quarter ended March 31, 2022.

2023 Focus

  • Clinical Data: Report clinical and translational science data from 15 to 20 additional patients treated with cNeT monotherapy in NSCLC and melanoma, and with a cNeT/anti-PD-1 checkpoint inhibitor combination in melanoma, in the fourth quarter of the year
  • Translational Science: Leverage the Company’s world-class translational science platform to define the cNeT product features associated with clinical responses
  • Clinical Activity: Drive the potential for additional confirmed responses in CHIRON and THETIS patients by delivering higher cNeT doses and improved product design
  • 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.

About Innovation Passport and ILAP

ILAP was launched by the MHRA in January 2021 with an aim to accelerate the development of and facilitate patient access to medicines. The Innovation Passport is granted by the UK’s ILAP Steering Group, which consists of representatives from MHRA, the National Institute for Health and Care Excellence (NICE), the Scottish Medicines Consortium (SMC), the All Wales Therapeutics and Toxicology Centre (AWTTC) and the National Health Service (NHS) England. It is the first step in the ILAP process and awarded to companies developing therapies with the potential to offer significant benefit to patients who have conditions that are life-threatening or seriously debilitating. Additional information is available on the UK government website.
