Summary

This study tests whether adding an immunotherapy drug (serplulimab) to standard chemotherapy before surgery can improve outcomes for people with a common type of locally advanced rectal cancer (MSS/pMMR). About 128 participants will be randomly assigned to receive either chemo alone or chemo plus immunotherapy for six cycles before surgery. The main goal is to see if the combination leads to a higher rate of complete cancer disappearance (pathological complete response).

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

mFOLFOX6 chemotherapy and serplulimab (an immunotherapy drug)

What this could lead to

If successful, this combination could increase the chance of eliminating all cancer before surgery, potentially reducing the need for more aggressive treatments.

What could go wrong

This is an early phase 2 trial with only 128 participants, so results may not apply to everyone. Immunotherapy can cause immune-related side effects, and the added benefit over chemotherapy alone is uncertain.
