Triple-Drug attack aims to shrink tough colorectal tumors before surgery

NCT ID NCT07365592

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether adding an immunotherapy drug (anti-PD-1) and a diabetes drug (sitagliptin) to standard chemotherapy can shrink tumors before surgery in people with locally advanced colorectal cancer that has a specific genetic profile (pMMR). About 138 adults aged 18–75 will receive the combination for two cycles before surgery. The goal is to see if the treatment is safe and helps reduce tumor size.

What this could mean

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

Active substance
chemotherapy (oxaliplatin and capecitabine) plus an anti-PD-1 antibody and sitagliptin
What this could lead to
If successful, this combination could shrink tumors before surgery in patients with a hard-to-treat form of colorectal cancer, potentially improving surgical outcomes and long-term control.
What could go wrong
This is an early-phase trial (Ib/II) with a small number of participants, so results may not apply broadly. Adding more drugs also raises the risk of side effects.
