Summary

This phase 2 trial is testing whether adding an experimental drug called DCSZ11 to standard radiation and chemotherapy can improve outcomes for people with a high-risk type of rectal cancer. The study will enroll 30 adults who have not had prior treatment. The goal is to see if the combination leads to a complete disappearance of the tumor before surgery, either through pathology or imaging.

What this could mean

Active substance

DCSZ11 (a CD93 inhibitor) combined with radiation and capecitabine/oxaliplatin chemotherapy

What this could lead to

If successful, this combination could increase the chance of eliminating the tumor before surgery, potentially allowing some patients to avoid surgery altogether.

What could go wrong

This is a small, early-phase trial with only 30 participants. The drug combination may cause significant side effects, and it is not yet known if it will improve long-term outcomes.
