About Achilles Therapeutics

Achilles Therapeutics is a clinical stage, biopharmaceutical company developing personalised 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/II studies, the THETIS study in patients with recurrent or metastatic malignant melanoma and the CHIRON study in patients with advanced non-small cell lung cancer (NSCLC). Achilles uses DNA sequencing data from each patient, together with the proprietary PELEUS™ bioinformatics platform, to identify clonal neoantigens specific to that patient, and then develop personalised T cell-based therapies specifically targeting those clonal neoantigens.
Achilles was founded in 2016 by lead investor Syncona Ltd and in September 2019 the Company raised £100M in an oversubscribed Series B financing led by RA Capital, cornerstoned by Syncona and joined by new investors including Forbion, Invus, Perceptive Advisors and Redmile Group.
