New imaging agent aims to spot Hard-to-Find kidney cancer spread
NCT ID NCT07062549
First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time
Summary
This early study tests whether a new radioactive tracer called 111In-XYIMSR-01 can help detect clear cell kidney cancer that has spread to other parts of the body. Six adults with confirmed metastatic clear cell renal cell carcinoma will receive the tracer and then undergo a SPECT/CT scan. The main goals are to check the tracer's safety and see how well it highlights cancer tissue.
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 tracer called 111In-XYIMSR-01
- What this could lead to
- If successful, this could lead to a more accurate way to detect metastatic clear cell kidney cancer using SPECT/CT scans.
- What could go wrong
- This is a very early, small study with only 6 participants, so results may not apply broadly. The tracer may not reliably detect tumors or could cause unexpected side effects.

Inclusion Criteria: * Males or female sex * ≥18 years of age * Willingness to provide signed informed consent and comply with all protocol requirements * Histological confirmation of RCC with a clear cell component * 2-10 sites of disease measuring ≥1.5 cm on contrast-enhanced CT and/or MRI imaging of the chest, abdomen and pelvis performed ≤60 days prior to the date of study enrollment * Screening clinical laboratory values as specified below: * Serum bilirubin ≤ 1.5 times the upper limit of normal; for patients with known Gilbert's syndrome, ≤ 3 × ULN is permitted * ALT ≤ 3 times the upper limits of normal * AST ≤ 3 times the upper limits of normal * Creatinine clearance ≥50 mL/min based on Cockcroft-Gault formula * Absolute neutrophil count ≥ 1,500 /mm3 * Platelets ≥100,000/ mm3 * Hemoglobin ≥ 9.0 g/dL * White blood cell count ≥ 2,000/ mm3 Exclusion Criteria: * Systemic therapy for the treatment of ccRCC within 12 months of study enrollment. * Subjects administered any radioisotope within five physical half-lives prior to study drug injection. * Subjects with any medical condition or other circumstances that, in the opinion of the investigator, compromise obtaining reliable data, achieving study objectives, or completion. * Women of child-bearing potential (WOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin) within 24 hours prior to the imaging day. * Women must not be breastfeeding.
