Abstract: Many approaches to identify therapeutically relevant neoantigens couple tumor sequencingwith bioinformatic algorithms and inferred rules of tumor epitope immunogenicity.However, there are no reference data to compare these approaches, and the parametersgoverning tumor epitope immunogenicity remain unclear. Here, we assembled a globalconsortium wherein each participant predicted immunogenic epitopes from shared tumorsequencing data. 608 epitopes were subsequently assessed for T cell binding in patient-matchedsamples. By integrating peptide features associated with presentation and recognition,we developed a model of tumor epitope immunogenicity that filtered out 98% of non-immunogenicpeptides with a precision above 0.70. Pipelines prioritizing model features had superiorperformance, and pipeline alterations leveraging them improved prediction performance.These findings were validated in an independent cohort of 310 epitopes prioritizedfrom tumor sequencing data and assessed for T cell binding. This data resource enablesidentification of parameters underlying effective anti-tumor immunity and is availableto the research community.
