BreAK CRC (001) trial
EU CTIS ID: 2024-512011-45-00
What this study is testing
Primary objectives for the Phase I: To characterize the overall safety profile of the STC-1010 + IS regimen administered with SOC therapy to participants with unresectable locally advanced or metastatic CRC and to determine the RP2D and the MTD. Primary objectives for the Phase IIA: To determine the clinical efficacy of STC-1010 + IS regimen when administered with SOC therapy to participants with locally advanced or metastatic unresectable CRC.
