Study summary

Brenetafusp (IMC-F106C) is an immune-mobilizing monoclonal T cell receptor against cancer (ImmTAC ®) designed for the treatment of cancers positive for the tumor-associated antigen PRAME. This is a first-in-human trial designed to evaluate the safety and efficacy of brenetafusp in adult participants who have the appropriate HLA-A2 tissue marker and whose cancer is positive for PRAME.
