New immunotherapy combo tested before surgery for various cancers

NCT ID NCT06279130

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study is testing two immunotherapy drugs, botensilimab and balstilimab, given before surgery to people with resectable solid tumors that are either mismatch repair deficient (dMMR) or proficient (pMMR). The goal is to see if this combination can shrink tumors significantly, measured by how much viable tumor remains after surgery. About 133 adults with non-metastatic cancers will participate.

What this could mean

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

Active substance
botensilimab and balstilimab (immunotherapy drugs)
What this could lead to
If successful, this could show that combining these immunotherapies before surgery helps shrink or eliminate tumors in multiple cancer types, potentially improving outcomes.
What could go wrong
This is a mid-stage trial with only 133 participants, and results may not apply to all cancers. Immunotherapies can cause immune-related side effects, and not all patients may respond.
