NCT ID NCT04115306

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

Summary

This study tests an experimental oral drug called PMD-026 in people with metastatic breast cancer that has spread and is no longer curable. The drug targets a protein called RSK2 found in some tumors. The trial will check safety and how well the drug works alone or with another hormone therapy (fulvestrant). About 61 participants will be enrolled.

What this could mean

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

Active substance

PMD-026 (oral targeted drug) and fulvestrant (hormone therapy)

What this could lead to

If successful, this could lead to a new oral treatment option for people with a specific type of advanced breast cancer that has stopped responding to other therapies.

What could go wrong

This is an early-phase trial with only 61 participants, so the drug may not prove effective or safe enough for wider use. Side effects are unknown at this stage.
