New drug cocktail aims to shrink aggressive breast tumors before surgery

NCT ID NCT07371208

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

Summary

This phase II trial is testing a combination of two drugs—Sac-TMT (a targeted chemotherapy) and KL-A167 (an immunotherapy)—given before surgery to 40 people with triple-negative breast cancer. The goal is to see if the combo can eliminate or shrink tumors enough to improve long-term outcomes. Participants will receive the drugs for 12 to 24 weeks, then have surgery to assess response.

Active substance

Sacituzumab tirumotecan (Sac-TMT) and KL-A167 (a PD-L1 inhibitor)

What this could lead to

If successful, this combination could shrink tumors before surgery, potentially improving outcomes for people with triple-negative breast cancer.

What could go wrong

This is a small, early-phase trial (40 people) with no control group, so results may not apply broadly. Side effects from the drug combination are possible.
