Since 2015 we are systematically exploring the TIL-repertoires of various solid cancers. Based on more than 100 surgical samples we can clearly say that the presence of tumor-specific T-cells in human tumors is more the rule than an exception. Why not send the best T-cells to fight cancer?
Our approach is based on natural tumor-specific T-cell receptors (tsTCRs) in individual patients with solid cancers. These T-cells had escaped negative selection in the thymus and after their encounter with tumor antigens have evolved into dominant tumor specific T-cell clones.
Employing proprietary technologies of special tissue handling and immune-sequencing, TheryCell is able to decipher complex T-cell repertoires in the tumor (TILs) and to identify the ones being most relevant: The tumor reactive T-cells.
Sequencing of the alpha/beta TCRs of these cells provides us with the basis for a truly tumor-specific personalized TCR-gene therapy.
We use state-of-the-art non-viral technologies for the genetic engineering of T cells with the identified tumor-specific TCRs. This is an essential step to bring manufacturing costs for therapeutic TCR-T cells into an affordable range.
For such treatment a high safety and efficacy can be expected as the TCRs have been selected in vivo and patient selection criteria such as HLA compatibility and antigen expression can be omitted.
