New drug cocktail takes on rare, aggressive breast cancer

NCT ID NCT03202316

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

Summary

This phase II trial tests whether combining an immunotherapy (atezolizumab), a targeted therapy (cobimetinib), and a chemotherapy (eribulin) can shrink tumors in people with inflammatory breast cancer that has returned or spread. About 37 participants will receive either the triple combo or a double combo (atezolizumab plus eribulin). The main goal is to see how many patients respond, while also monitoring side effects.

Active substance
atezolizumab, cobimetinib, and eribulin
What this could lead to
If successful, this could point toward a new combination treatment for inflammatory breast cancer that has spread, potentially improving response rates.
What could go wrong
This is a small, early-phase trial (37 people) with no control group, so results may not apply broadly. Side effects from the drug combination could be significant.
