NCT ID NCT06067503
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study is looking for better ways to see if endocrine therapy is working in people with a type of breast cancer called metastatic invasive lobular carcinoma. Researchers will use a special PET scan and blood tests to measure changes in estrogen signaling after 4 weeks of treatment. The goal is to find early signs of resistance, so doctors can adjust treatment sooner. Only 8 participants are being enrolled.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
18F-fluorofuranylnorprogesterone (FFNP) and liquid biopsy
What this could lead to
If successful, this could lead to a way to quickly tell if endocrine therapy is working, helping doctors switch treatments sooner for patients with metastatic lobular breast cancer.
What could go wrong
This is a very small pilot study with only 8 participants, so results may not apply to everyone. It is designed to gather information, not to test a new treatment.
