Proceeds will be used to progress the development of new therapies that act on peptide-loaded major histocompatibility complexes (pMHCs) present on cancer cells.
To target pMHCs, these therapies will leverage antibodies that imitate T-cell receptors (TCR-mimetics).
The company will identify, validate and select the most promising cancer-specific targets, then create TCR-mimetic antibodies that have greater levels of cancer cell affinity and specificity.
Such TCR-mimetics will be merged with off-the-shelf T-cell engagers and immunotherapies to create tumour-bolt (T-Bolt) molecules.

Crossbow Therapeutics CEO Briggs Morrison stated: “With unparalleled accuracy and potency, our revolutionary T-Bolt products strike cancer cells like a crossbow shoots bolts at its target.
“The influx of additional capital enables us to scale our efforts to build an arsenal of TCR-mimetic-based immunotherapies designed to overcome the limitations of current treatments.”
