What the film says

Read the transcript

This trial is for adults with untreated stage two or three rectal adenocarcinoma that is mismatch-repair-proficient or microsatellite-stable. Distant spread and recurrent rectal cancer exclude participation.

The idea: botensilimab targets CTLA4 and balstilimab targets PD1, two immune brakes. Researchers assess the combination before local treatment. MRI and endoscopy measure partial, near-complete, or complete clinical response. The study also examines safety. The public record does not specify doses, schedules, or when standard chemotherapy may be added.

This phase 2 study plans 40 patients. Andrea Cercek leads at MSK, New York; seven US sites recruit.
