About this study

This is an open-label, non-randomised FIH trial investigating the safety and tolerability of a novel ATMP, pTTL, composed of autologous tumour-draining lymph node-derived T cells stimulated in vitro with personalised cancer neoantigens. The neoantigens are selected through a process starting with next generation sequencing (NGS) of tumour material from the patient followed by selection of neoantigenic mutations using an in-house software, PIOR®. Selected neoantigen epitopes are expressed as recombinant proteins, NAG, and used to stimulate T cells to promote neoantigen-specific T cell expansion in vitro in pTTL production. pTTL is thus based on autologous cells stimulated with patient-specific neoantigens. In consequence, every pTTL product is unique and designated for use in one single individual. pTTL will be administered to patients with stage IV colorectal cancer (CRC) as a single intravenous dose.
