New drug combo aims to eliminate rectal tumors before surgery

NCT ID NCT07104604

First seen Jul 14, 2026 · Last updated Jul 24, 2026 · Updated 3 times

Summary

This phase 2 trial tests whether adding a new form of chemotherapy (liposomal irinotecan) to standard radiotherapy, immunotherapy (tislelizumab), and another chemotherapy (capecitabine) can make advanced rectal cancers disappear before surgery. The study enrolls adults aged 18–75 with a specific type of locally advanced rectal cancer (pMMR) that has high-risk features. The main goal is to see how many patients achieve complete remission—no sign of cancer after treatment.

What this could mean

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

Active substance
a combination of radiotherapy, tislelizumab (an immunotherapy), liposomal irinotecan (a chemotherapy), and capecitabine (a chemotherapy)
What this could lead to
If successful, this combination could increase the chance of complete tumor disappearance before surgery, potentially allowing more patients to avoid permanent colostomy and improving long-term outcomes.
What could go wrong
This is a small, early-phase trial (51 participants) testing a new drug formulation (liposomal irinotecan) in a specific patient group, so results may not apply broadly. The combination also carries risks of side effects from chemotherapy, immunotherapy, and radiation.
