Trop2-targeted immunoPET Imaging of Solid Tumors

This study is testing a new type of PET scan imaging that uses a radiotracer targeting Trop2 — a protein overexpressed on many cancer types — to non-invasively detect and measure Trop2 expression in solid tumors, which could help guide treatment decisions for Trop2-targeted therapies. **You may be eligible if...** - You are between 18 and 75 years old - You have a confirmed or suspected solid tumor, including cancers of the bladder, prostate, lung, nasopharynx, liver, bile ducts, ovaries, cervix, uterus, thyroid, or head and neck - You are able to undergo a PET scan - You have provided written informed consent **You may NOT be eligible if...** - You have a cancer type not listed among the eligible solid tumors - You have significant kidney problems that would make the imaging agent unsafe - You are pregnant or breastfeeding - You have previously had a severe allergic reaction to similar imaging agents Talk to your doctor to see if this trial is right for you.
