Neoantigen AI Platform

  Precision Immunotherapy Discovery

PharmaPlanter’s Neoantigen AI platform is an industry-leading computational and experimental ecosystem designed to identify and validate high-confidence neoantigens for personalized cancer vaccines and TCR-T cell therapies. By fusing deep learning algorithms with high-throughput laboratory validation, we bridge the gap between genomic data and actionable clinical candidates.

Our platform enables:

  • Intelligent Neoantigen Prediction: Our platform utilizes advanced neural networks trained on vast immunopeptidome datasets to predict MHC-peptide binding affinity, stability, and cell-surface presentation with exceptional accuracy. Beyond simple binding, our AI integrates T-cell receptor (TCR) cross-reactivity modeling to prioritize neoantigens with the highest potential for inducing a robust and specific immune response.

  • Immunogenic Prioritization Engine: We move beyond raw data by incorporating tumor-specific factors, such as gene expression levels and proteasomal processing efficiency. This multi-layered filtering system significantly reduces "false positives," ensuring that only the most immunogenic and clinically relevant neoantigens move forward into the development pipeline.

  • High-Fidelity Antigen Synthesis & Characterization: Leveraging our Recombinant Protein Platform, we produce high-purity neoantigen peptides and peptide-MHC (pMHC) complexes. Each candidate is characterized for structural stability and binding kinetics using SPR/BLI to ensure they meet the stringent biophysical criteria required for therapeutic use.

  • Multi-Dimensional Immunogenicity Validation: We conduct comprehensive functional screening through ELISA, ELISpot, and FACS-based multimer staining. These assays measure the actual activation and expansion of antigen-specific T-cells, providing laboratory proof of the AI-predicted immunogenicity.

  • Integrated In Vivo Verification: To support translational proof-of-concept, we validate neoantigen candidates in humanized mouse models. By evaluating T-cell infiltration and anti-tumor efficacy in a physiological context, we provide the critical data necessary to transition from computational prediction to clinical development.
