While there has been a growing appreciation for the potential of neoantigen-based immune-oncology therapy, the industry faces two significant challenges in developing effective neoantigen treatments:

1) Low accuracy in predicting and choosing neoantigens; 

2) Low delivery efficiency of cancer vaccines


The combined result is a low therapeutic potency of cancer vaccine treatments, which decrease the viability of neoantigen therapeutics for a broader range of cancer treatments.

Our Solutions

PepGene combines its unique advantages in both computational and experimental platforms to develop personalized cancer vaccines as a valid and low-risk treatment feasible to a wide range of cancer patients:

Novel Neoantigen Sources

The majority of current neoantigen predictions and investigations focus on somatic mutations such as SNVs and INDELs, which limits the sources of potential neoantigens. PepGene’s algorithm aims to cover neoantigens from both coding regions (SNV and INDEL) and non-coding regions, which has been reported to generate more neoantigens than coding regions.
