New cocktail of drugs tested for Hard-to-Treat breast cancer – but trial halted early

NCT ID NCT03801369

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

Summary

This phase II study tested several drug combinations for people with metastatic triple-negative breast cancer, a type that has spread and lacks common hormone targets. The drugs included olaparib (a PARP inhibitor) paired with either durvalumab (an immunotherapy), selumetinib, capivasertib, or ceralasertib alone. The goal was to see if these combinations could shrink tumors. However, the trial was terminated early after enrolling only 24 participants, so the findings are limited.

Active substance

Olaparib, durvalumab, selumetinib, capivasertib, ceralasertib

What this could lead to

If successful, these drug combinations could offer new treatment options for people with metastatic triple-negative breast cancer that has stopped responding to standard therapies.

What could go wrong

This trial was terminated early with only 24 participants, so results are very limited. It is unclear if any of the combinations are effective or safe enough to move forward.
