New minor risk - Share price stability The company's share price has been volatile over the past 3 months. It is more volatile than 75% of American stocks, typically moving 10% a week. This is considered a minor risk. Share price volatility indicates the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. It also increases the risk of potential losses in the short term as the stock tends to have larger drops in price more frequently than other stocks. Currently, the following risks have been identified for the company: Major Risks Earnings are forecast to decline by an average of 21% per year for the foreseeable future. Revenue is less than US$1m. Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$119m net loss in 3 years).

Achilles Therapeutics plc Provides Interim Phase I/IIa Update on Clonal Neoantigen Reactive T Cells in Advanced NSCLC and Melanoma Including First Patients Dosed with Enhanced Host Conditioning Achilles Therapeutics plc announced interim Phase I/IIa data on the use of clonal neoantigen reactive T cells (cNeT) from the CHIRON study in advanced unresectable or metastatic non-small cell lung cancer (NSCLC) and the THETIS study in recurrent or metastatic malignant melanoma. The update includes data from 18 patients across CHIRON (n=12) and THETIS (n=6) dosed since the previous interim update in December 2022, with two CHIRON patients and one THETIS patient having received enhanced chemo-conditioning and IL-2 dosing aligned to standard tumor infiltrating lymphocyte (TIL) therapy (enhanced host conditioning) in a new Cohort C. This new Cohort C will allow the impact of enhanced host conditioning on cNeT engraftment and persistence beyond 28 days to be evaluated. All trial participants were late-stage, checkpoint refractory patients with progressive disease at the time of lymphodepletion. The observed tolerability profiles remain favorable and similar to standard TIL therapy. The VELOS™ manufacturing process continued to improve with a median 172 million cNeT dosed across the eighteen patients in the update compared to 18 million cNeT in the December 2022 update, with 10 products over 100 million cNeT and five over one billion cNeT. Summary of new patients treated since the previous update: 18 new patients treated since the last update (12 NSCLC in CHIRON, 6 melanoma in THETIS) with a median of two prior lines of therapy; Data update includes two CHIRON Cohort C (enhanced host conditioning), one THETIS Cohort C and two THETIS Cohort B patients (checkpoint combination); Median cNeT dose of 172 million in the 18 patients reported since the last update with 10 of 18 patients dosed with over 100 million cNeT, including five products over one billion cNeT. Continued favorable tolerability profile for cNeT: Tolerability observations for cNeT compare well with standard TIL therapy; Lymphopenia and neutropenia were the most common adverse events, which are principally associated with the conditioning regimen, and no dose limiting high-grade toxicities were observed. 25% of higher dose (>100M cNeT) patients in CHIRON and THETIS (3 of 12) demonstrated stable disease with some reduction in tumor volume: No new objective responses were observed, which is believed to relate to a lack of cNeT persistence with the previous host-conditioning regimen using lower lymphodepletion and IL-2 compared to standard TIL therapy; Early and significant peaks of cNeT, similar to standard TIL therapy, were observed in the blood of patients receiving reduced intensity conditioning, though with a lack of consistent cNeT persistence beyond 28 days. Enhanced host conditioning cohort opened in CHIRON and THETIS: Enhanced host conditioning protocol Cohort C has been added to CHIRON and THETIS to evaluate an enhanced regimen of increased lymphodepletion intensity and increased IL-2 dosing on cNeT persistence and hence potentially clinical activity; All three patients dosed using the enhanced host conditioning regimen have shown improvement in cNeT engraftment and some tumor reduction in one case; TCR tracking shows more durable cNeT engraftment beyond week six in the first patient treated with enhanced host-conditioning regimen; A further eight patients are currently under observation with products ready for dosing with a cNeT product. VELOS Manufacturing process further enhanced: 172 million median cNeT dose for the last 18 patients in this update compared to a median of 18 million cNeT in the December 2022 update; The last 10 products manufactured have delivered a median cNeT dose of 611 million.

Achilles Therapeutics plc Announces New Immunogenicity Prediction Application of its AI-Powered PELEUS Platform Uniquely Identifies Most Potent T Cell Antigens Achilles Therapeutics plc announced that the Company’s new AI application, trained with proprietary real-world data, outperformed current AI and non-AI methods for neoantigen immunogenicity prediction in a recent analysis, enabling the identification of the most potent clonal neoantigens for personalized cancer therapies. Further details of this new capability of the Company’s AI-powered PELEUS™ bioinformatics platform are expected to be presented at an upcoming scientific meeting. Of the large numbers of neoantigens that are initially identified in a patient’s tumor, only a fraction will yield T cell responses that can deliver clinical benefit. Achilles has developed an AI tool to enable the prospective identification of the most potent neoantigens. The new PELEUS™ neoantigen immunogenicity ranking module was trained and validated with data from over 10,000 neoantigens from in-silico identification through expansion and characterization of actual T cell clones. With this new tool, the PELEUS™ platform can accurately predict which neoantigens are most likely to generate a potent T cell response, supporting the potential implementation of the platform 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. The analysis conducted by the Bioinformatics & Data Science Team at Achilles demonstrated that the PELEUS™ platform delivered significantly improved ranking performance when compared to currently used state-of-the-art methods as measured by “Receiver Operating Characteristic Area Under the Curve” (ROC AUC). ROC AUC evaluates the performance of a machine learning model to predict neoantigens that are confirmed in vivo. The PELEUS™ AI immunogenicity ranking tool was developed and trained using proprietary real-world data from patient material from Achilles’ Material Acquisition Program (MAP), the ongoing CHIRON trial in patients with advanced NSCLC, and the THETIS trial in patients with recurrent or metastatic melanoma. Current AI methods are trained on publicly available data from sources such as the Immune Epitope Database (IEDB), a freely available resource funded by the National Institute of Allergy and Infection Disease (NIAID).

Achilles Therapeutics plc Updates Interim Results from the Ongoing Phase I/IIa Chiron and Thetis Clinical Trials Achilles Therapeutics plc announced that an abstract highlighting updated interim results from the ongoing Phase I/IIa CHIRON and THETIS clinical trials evaluating clonal neoantigen-reactive T cells (cNeT) has been accepted for a poster presentation at the ESMO Immuno-Oncology Annual Congress (ESMO IO) taking place in Geneva, Switzerland from December 7-9, 2022. cNeT are the active component of the final, precision T cell product which target tumors through recognition of a patient’s clonal neoantigens present on all tumor cells. 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.
