Can a new tracer make tumors light up on scans?
NCT ID NCT07801508
First seen Sep 03, 2026 · Last updated Sep 09, 2026 · Updated 2 times
Summary
This trial tests an experimental imaging agent called [68Ga]Ga-DWJ155 in adults with advanced cancers of the breast, lung, or stomach. The agent is designed to attach to tumor cells and show up on PET scans, helping doctors see where cancer has spread. Researchers will measure how well the agent highlights tumors compared to normal tissue, and they will also check its safety and how the body processes it. The study includes people with specific types of advanced breast cancer, non-small cell lung cancer, and gastroesophageal adenocarcinoma.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A radioactive imaging agent called [68Ga]Ga-DWJ155 (also known as FKL480), given as an injection for PET scans
- What this could lead to
- If it works, this imaging agent could help doctors see tumors more clearly on PET scans, potentially guiding treatment decisions for several advanced cancers.
- What could go wrong
- This is an early phase 1 study with a small number of participants, so the imaging agent may not bind well to tumors or may not be safe. It is not yet known if it will improve cancer care.

Key Inclusion Criteria: * Age ≥ 18 years old * Presence of at least one extracranial measurable lesion by Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 * Eastern Cooperative Oncology Group (ECOG) performance status 0-2 * Patients with one of the following indications: * HR+/HER2- aBC and TNBC: untreated or currently receiving or having completed first line of systemic therapy (preferred); HER2+ aBC: regardless of any prior systemic therapy * aNSCLC adenocarcinoma: Prior to, during or having completed their first line of systemic therapy. If HER2 immunohistochemistry (IHC) will be routinely performed and available, then HER2 ≥1+ * aGEA: regardless of any prior systemic line of therapy Key Exclusion Criteria: * Out-of-range laboratory values defined as: * Estimated glomerular filtration rate (eGFR; calculated using CKD-EPI 2021 formula, or measured) \< 40 mL/min/1.73m2 * Platelet count \< 75 x 10\^9/L * Hemoglobin \< 9 g/dL * Absolute neutrophil count (ANC) \< 1.0 x 10\^9/L * Patients with inadequate hepatic function * Urinary tract obstruction or urinary incontinence * Pregnant or breastfeeding women Other protocol-defined inclusion/exclusion criteria may apply.
