New imaging agent could sharpen cancer detection
NCT ID NCT06977945
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new imaging agent called FL-091, which targets a protein (NTSR1) found on some cancer cells. Researchers will use it with PET or SPECT scans to see if it can better detect and stage cancers like head and neck, colorectal, and pancreatic cancer. About 100 adults with suspected or confirmed NTSR1-positive tumors will take part. The goal is to see how well the agent highlights tumors and where it goes in the body, laying groundwork for future targeted treatments.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- FL-091 (a radionuclide imaging agent)
- What this could lead to
- If successful, this could lead to a more accurate way to detect and stage certain cancers, potentially guiding better treatment decisions.
- What could go wrong
- This is an early diagnostic study with only 100 participants, so results may not apply to all patients. The imaging agent's effectiveness and safety are still being evaluated.

Inclusion Criteria: Each subject must meet all enrollment criteria to be eligible to participate in the study: 1. The subject or his/her legal representative is able to sign and date the informed consent form; 2. A commitment to comply with the research procedures and to cooperate in the implementation of the full research process; 3. Adult patients or healthy volunteers (aged 18 or above) of either sex; 4. Patients with clinically suspected or confirmed malignant tumors such as head and neck cancer, colorectal cancer, or pancreatic cancer (supporting evidence includes serum-related tumor markers, imaging data such as ultrasound, CT, MRI, etc., and histological pathology examination, etc.) and in good general condition; 5. Consistent with the results of specific laboratory tests; 6. Females of childbearing potential who have been using contraception for at least one month prior to screening and who are committed to using contraception for the entire study period and until a specified time after the end of the study; 7. Other set entry criteria. Exclusion Criteria: All subjects who meet any of the exclusion criteria baseline will be excluded from the study: 1. Those who are unable to complete a PET/MR or PET/CT examination (including inability to lie down, claustrophobia, radiophobia, etc.); 2. Having other comorbidities; 3. Patients with known hypersensitivity to FL-091 fragment developers or synthetic excipients; fasting blood glucose level greater than 11.0 mmol/L prior to 18F-FDG injection; 4. Have a history of comorbid drug use; 5. Patients considered by the investigator to have poor compliance; 6. Patients during pregnancy or lactation; 7. Persons with other factors that make participation in this test inappropriate.
