• Accelerating Bio-Innovation 2022 in Cambridge, UK on Tuesday, April 5, 2022 at 2:25pm UK. Iraj Ali, CEO, will participate in a panel entitled, “Next-Gen Immuno Oncology.”
• 21^st Annual Needham Virtual Healthcare Conference on Tuesday, April 12, 2022 at 8:00am ET / 1:00pm UK. Iraj Ali, CEO, will give a corporate presentation.
• 14^th Kempen Life Sciences Conference in Amsterdam, Netherlands on Wednesday, April 20, 2022. Iraj Ali, CEO, and Robert Coutts, CFO, will participate in one-on-one and small group investor meetings.
• Chardan’s 6^th Annual Virtual Genetic Medicines and Cell Therapy Manufacturing Summit on Monday, April 25, 2022 at 11:00am ET / 4:00pm UK. Iraj Ali, CEO, and Edward Samuel, EVP Technical Operations, will participate in a fireside chat.

Additionally, as was announced previously, the Company will host a key opinion leader (KOL) webcast on Thursday, April 14, 2022 at 10:30am ET / 3:30pm UK featuring Professor Charles Swanton of Cancer Research UK, TRACERx Chief Investigator and Achilles co-founder. Professor Swanton and the panel will discuss the importance and unique utility of the TRACERx study in validating the identification of clonal neoantigens as targets for personalized T cell therapies and highlight selections from the 31 posters and presentations on the TRACERx study presented at the 2022 AACR Annual Meeting.

Details for live and archived webcasts of available presentations will be posted in the Events & Presentations section of the Achilles website.

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 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 TRACERx
TRACERx (TRAcking Cancer Evolution through therapy (Rx)), led by Professor Charles Swanton at UCL, is one of the largest tumor evolution studies to generate deep sequencing multi-region and multi-time point genetic data from over 3,200 tumor samples from nearly 800 lung cancer patients. TRACERx has transformed the understanding of tumor evolution and has convincingly shown that tumors originate from a single cell that evolves in a Darwinian manner and the early (clonal) mutations are preserved in all subsequent primary and metastatic tumor cells. The study, which has generated numerous publications, uncovered important mechanisms of cancer evolution and immune evasion by analyzing genetic signatures in lung tumors and tracking how they evolve over time from diagnosis through to relapse. These findings provide the ability to identify a novel class of tumor markers called clonal neoantigens that are present on all tumor cells yet absent from healthy tissue, making them ideal cancer targets. TRACERx represents the largest investment in lung cancer research by Cancer Research UK and Achilles has exclusive commercial rights to the TRACERx study data for development of neoantigen-targeting cell therapies.

About PELEUS
PELEUS is a proprietary, AI-powered bioinformatics platform built and validated through exclusive access to TRACERx knowhow and genomics data. PELEUS uses sophisticated Bayesian statistical algorithms to distinguish which mutations, or neoantigens, in a patient’s tumor are clonal or subclonal by synthesizing DNA sequencing information from multiple tumor regions. Clonal neoantigens are protein markers that are present on all of an individual’s cancer cells but are absent from healthy tissue, making them ideal cancer targets. The information from PELEUS provides the foundation for Achilles’ VELOS manufacturing process to produce clonal neoantigen-reactive T cells, or cNeT.
