Clinical summary

Summary

This study is evaluating IMC-F106C, an immune-mobilising monoclonal T cell receptor against cancer that is designed for the treatment of cancers positive for the tumour-associated antigen PRAME. The study will be conducted in two phases:

Phase 1: Aims to identify the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) of IMC-F106C as a single agent and administered in combination with a checkpoint inhibitor, chemotherapy, or another ImmTAC molecule.

Phase 2: Aims to assess the efficacy of IMC-F106C as a single agent in selected advanced solid cancers.
