LONDON, Aug. 09, 2022 (GLOBE NEWSWIRE) -- Achilles Therapeutics plc (NASDAQ: ACHL), a clinical-stage biopharmaceutical company developing precision T cell therapies to treat solid tumors, today announced its financial results for the second quarter ended June 30, 2022, and recent business highlights.

“We remain focused on advancing our lead clinical programs, evaluating cNeT monotherapy in CHIRON for advanced non-small cell lung cancer (NSCLC), and exploring both cNeT monotherapy and the combination with a PD-1 checkpoint inhibitor in THETIS for recurrent or metastatic malignant melanoma. We expect initial activity, safety and translational science data in the fourth quarter of this year from patients receiving higher-dose cNeT products,” said Dr Iraj Ali, Chief Executive Officer of Achilles Therapeutics. “We are very pleased that the UK Medicines and Healthcare products Regulatory Agency (MHRA) has now approved Achilles’ Cell and Gene Therapy Catapult Manufacturing Centre (Catapult) site to produce cNeT products in the ongoing CHIRON and THETIS clinical trials, significantly increasing our manufacturing capacity for 2022 and beyond.”

Business Highlights

• On track to present additional clinical data in Q4 2022 from the ongoing Phase I/IIa CHIRON and THETIS clinical trials in patients with advanced NSCLC and recurrent or metastatic melanoma, respectively.

• Expanded global manufacturing capacity with the MHRA approval of Achilles’ Catapult facility for cNeT production in CHIRON and THETIS and entered into a partnership agreement for clinical manufacturing in the United States with the Center for Breakthrough Medicines, a contract development and manufacturing organization in King of Prussia, PA.

• Awarded a €4 million ($4.2 million¹) research and innovation award as part of a consortium to develop a first-in-class smart bioprocessing manufacturing platform, with €1.4 million ($1.5 million¹) allocated to Achilles.

• Initiated the tumor archiving program (TAP) to study the potential of producing cNeT from tumor material collected and stored earlier in disease progression.

• Strengthened the Company’s leadership with the following appointments: Bernhard Ehmer to the Board of Directors, James Taylor as Chief Business Officer, and Cassian Yee, MD to the Scientific Advisory Board.

• Received the 2022 Pharmaceutical Industry Network Group (PING) Innovation Award, acknowledging the innovation demonstrated by the Company’s work with clonal neoantigens to treat solid tumors, including the Company’s AI-powered PELEUS™ bioinformatics platform and proprietary VELOS™ manufacturing process.

Financial Highlights

• Cash and cash equivalents: Cash and cash equivalents were $201.6 million as of June 30, 2022, as compared to $266.3 million as of December 31, 2021. 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.

The increase was primarily driven by increased activity related to our ongoing clinical trials and overall R&D.

• General and administrative (G&A) expenses: G&A expenses were $5.8 million for the second quarter ended June 30, 2022, as compared to $5.4 million for the second quarter ended June 30, 2021. The increase was primarily driven by an increase in headcount and related personnel costs.

About Achilles Therapeutics
Achilles is a clinical-stage biopharmaceutical company developing 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 AI-Powered 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.
