About this trial

The primary goal of Phase Ib Study is to evaluate the safety of Suvemcitug in combination with trifluridine/tipiracil tablets in colorectal cancer participants.

The primary goal of Phase III Study is to evaluate the efficacy of Suvemcitug in combination with trifluridine/tipiracil tablets in colorectal cancer participants. Researchers will compare Suvemcitug + trifluridine/tipiracil tablets with placebo (a look-alike substance that contains no drug)+ trifluridine/tipiracil tablets to see if Suvemcitug + trifluridine/tipiracil tablets works better in treating refractory metastatic colorectal cancer.
