  • Establishing a process for isolating cytotoxic T cells that can directly attack cancer cells, creating an MHC-TCR interaction environment, and utilizing MHC I/II blockers to achieve an immune microenvironment in vivo.
  • Since obtaining blood from cancer patients is limited, the process is refined by co-culturing peripheral blood mononuclear cells (PBMC) derived from healthy individuals with cancer organoids from cancer patients.
    This allows for the generation of cytotoxic T cells.

Characteristics

Evaluation of the efficacy of an immunotherapeutic agent targeting cytotoxic T cells is possible by co-culturing specific organoids with Primed
Cytotoxic T cells, allowing for the selective elimination of particular organoids.
This provides a solution for assessing the effectiveness of immunotherapeutic agents targeting cytotoxic T cells in co-culture with cancer organoids.

High Responder to control

Low Responder to control

Our cutting-edge platform brings approach in drug development, empowering clinicians and researchers to transcend beyond the binary classification of responders versus non-responders.
It facilitates a deeper examination of patient-specific responses to approved control drugs at various concentrations.
This technology illuminates the intricate interplay between genetic, regional, and environmental factors and their impact on drug efficacy, providing a path to address the pressing unmet needs in before clinical trail.

Combination

This example showcases the potential utility of our platform in identifying optimal partners for combination therapy with Immune Checkpoint Inhibitors (ICIs).
His suggests that Combination B could be a more effective strategy in enhancing the efficacy of ICIs.
This platform is designed to facilitate such discoveries, offering a clear pathway to improve clinical outcomes through strategic drug pairing.
