LONDON, Nov. 08, 2022 (GLOBE NEWSWIRE) -- Achilles Therapeutics plc (NASDAQ:ACHL), a clinical-stage biopharmaceutical company developing AI-powered precision T cell therapies to treat solid tumors, today announced its financial results for the third quarter ended September 30, 2022, and recent business highlights.

"This quarter we continued to advance our clinical programs and look forward to providing an update from our ongoing Phase I/IIa CHIRON and THETIS clinical trials in non-small cell lung cancer (NSCLC) and melanoma, respectively, at the ESMO Immuno-Oncology Annual Congress," said Dr Iraj Ali, Chief Executive Officer of Achilles Therapeutics. "A poster entitled ‘Early Proof of Concept of Safety and Clinical Activity of Clonal Neoantigen Reactive T Cells,' will be presented and available from December 6, 2022. We expect additional clinical data readouts across our programs throughout 2023 which, along with our strong cash balance, position Achilles well for the future."

Financial Highlights

• Cash and cash equivalents: Cash and cash equivalents were $179.9 million as of September 30, 2022, as compared to $266.3 million as of December 31, 2021. The impact of translating our books and records from British Pounds Sterling into U.S. dollars had an unfavorable impact on the reported balance cash and cash equivalents. The net decrease reflects an underlying use of $45.7 million for operating and investing activities and a negative $40.7 million foreign exchange impact. The Company anticipates that its cash and cash equivalents are sufficient to fund its planned operations into the second quarter of 2025, including completion of the ongoing Phase I/IIa CHIRON and THETIS clinical trials.
• Research and development (R&D) expenses: R&D expenses were $10.6 million for the third quarter ended September 30, 2022, as compared to $10.7 million for the third quarter ended September 30, 2021.
• General and administrative (G&A) expenses: G&A expenses were $5.4 million for the third quarter ended September 30, 2022, as compared to $5.0 million for the third quarter ended September 30, 2021. The increase was primarily driven by an increase in personnel costs.
• Net loss: Net loss for the third quarter ended September 30, 2022, was $12.5 million or $0.32 per share compared to $12.9 million, or $0.34 per share for the third quarter ended September 30, 2021.

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 develops precision T cell-based product candidates specifically targeting those clonal neoantigens.
