What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new imaging dye called 18F-4FN for special scans. It aims to help doctors see inflammation in patients, especially those with immune-related issues. The dye works by sticking to chemicals produced during inflammation, making these areas visible on scans.

Are You a Good Fit for This Trial?

Adults diagnosed with endocrine tumors or inflammation due to immune checkpoint inhibitors can join. They must have normal kidney and liver function, not be allergic to the test substance, and weigh less than 400 pounds. Pregnant women, lactating mothers, and children under 18 are excluded.

Inclusion Criteria

My kidney and liver function tests are within normal ranges.

I have a tumor and have had side effects from immune therapy or suspected inflammation.

Exclusion Criteria

You weigh more than 400 pounds or your body mass index (BMI) is too high for the PET/CT scanner to safely support your weight.

I am not allergic to [18F]4FN.

Any additional medical condition, serious concurrent illness, or other extenuating circumstance that, in the opinion of the physician may significantly interfere with study compliance
