What You Need to Know Before You Apply

What is the purpose of this trial?

Current tests to detect cancer, including CAT scans and MRI scans, are limited. PET scans use special dyes that are injected into a vein and can better localize possible cancer. The investigators have developed a new particle that can carry a radioactive dye to a very specific area of the tumor. When using a PET scan the radioactive dye can be viewed in areas of possible disease. This particle has been studied in mice and was safe.The particles will not treat the cancer and any images or information found during this study will not be used for your treatment. The information collected may be used to guide the design of future studies to detect and/or treat tumors.

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial team or your doctor.

Is 124I-cRGDY-PEG-dots safe for use in humans?

In a clinical trial with patients having metastatic melanoma, the 124I-cRGDY-PEG-C dot particles were found to be well-tolerated with no toxic or adverse events observed. The particles showed stable behavior in the body and were safely excreted through the kidneys.12345

How does PET imaging for melanoma differ from other treatments?

PET imaging for melanoma is unique because it uses specialized radiotracers, like 18F-PEG3-FPN, to detect melanoma metastases with high precision, particularly in the liver and lungs, while minimizing liver uptake. This approach allows for better visualization of cancer spread compared to traditional imaging methods.24678

Are You a Good Fit for This Trial?

This trial is for adults with a confirmed diagnosis of melanoma or malignant brain tumor at MSKCC, who may have had prior treatments like surgery, chemo, or radiation. They must be able to use birth control and not have other recent cancers (except the one being studied), uncontrolled illnesses, severe heart disease, thyroid dysfunction, allergies to iodine contrast material, weigh over 400 lbs., or suffer from claustrophobia.

Inclusion Criteria

I was recently diagnosed and had a lump removed for testing.
All patients of childbearing and child-creating age must be using an acceptable form of birth control
If you are a woman who has not gone through menopause, you need to have a negative pregnancy test.

Exclusion Criteria

I cannot stay still in a scanner for 30 minutes.
I do not have severe health issues that would prevent me from receiving the tracer.
I have had cancer other than melanoma or brain cancer, but have been disease-free for less than 5 years.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Microdosing Study

What Are the Treatments Tested in This Trial?

Interventions

  • 124I-cRGDY-PEG-dots
Trial Overview The study tests a new PET scan dye carried by nanoparticles designed to target cancer areas more precisely than current imaging methods. This microdosing study aims to see how well the dye works in humans after being proven safe in mice. It's important to note that this particle won't treat cancer; it's purely for improving detection.
