A First in Human Study Using 89Zr-cRGDY Ultrasmall Silica Particle Tracers for Malignant Brain Tumors

Study Purpose

The purpose of this study is to test if PET scans using 89Zr-DFO-cRGDY-PEG-Cy5-C' dot particles, can be used to take pictures of brain tumors. The investigators want to understand how the particles are distributed and removed from the body, which may help others be treated in the future. This will be the first time that 89Zr-DFO-cRGDY-PEG-Cy5-C' dot particles are being used in people. The amount of particles given in this study is very small compared to the amount that was used in mice animal studies.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over
Gender All
More Inclusion & Exclusion Criteria

Inclusion Criteria:

  • - 18 years of age or older.
  • - Histologically confirmed diagnosis of malignant primary brain tumor clinical and radiographic findings consistent with a pituitary adenoma, or known metastatic cancer with brain lesion presumed to be metastatic.
  • - Normal baseline cardiac function based upon pre-operative evaluation at the physcian's discretion.
  • - All patients of childbearing age must use an acceptable form of birth control.
  • - Women who are pre-menopausal must have a negative serum pregnancy test.

Exclusion Criteria:

  • - Known pregnancy or breast-feeding Medical illness unrelated to the tumor which in the opinion of the attending physician and principal investigator will preclude administration of the tracer.
°This includes patients with uncontrolled infection, chronic renal insufficiency, myocardial infarction within the past 6 months, unstable angina, cardiac arrhythmias other than chronic atrial fibrillation and chronic active or persistent hepatitis, or New York Heart Association Classification III or IV heart disease.
  • - More than one metastatic cancer active in the last 5 years.
  • - Active metastatic cancer in addition to malignant primary brain tumor.
  • - Weight greater than the 400-lb weight limit of the PET scanner.
  • - Unmanageable claustrophobia.
- Inability to lie in the scanner for 30 minutes

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Arms & Interventions


Experimental: surgical patients

Patients will be i.v. injected with approximately 5 mCi (~3.4-6.7 nanomoles) of 89Zr-DFO-cRGDY-PEG-Cy5-C' dots (specific activity range 750.0 - 1450 mCi/ µmol) and undergo the microdosing study for purposes of collecting particle tracer kinetic and dosimetry data. The patient's PET/CT Brain scans may be acquired prior to surgery. All non-surgical and some surgical patients (at the discretion of the physician) will undergo PET brain imaging.

Experimental: non-surgical patients

Before the patient's PET Brain scans patients will be i.v. injected with approximately 5 mCi (~3.4-6.7 nanomoles) of 89Zr-DFO-cRGDY-PEG-Cy5-C' dots (specific activity range 750.0 - 1450 mCi/ µmol) and undergo the microdosing study for purposes of collecting particle tracer kinetic and dosimetry data. All non-surgical and some surgical patients (at the discretion of the physician) will undergo PET brain imaging


Drug: - 89Zr-DFO-cRGDY-PEG-Cy5-C' dots PET Imaging

A low dose spiral CT is performed first per the standard procedure. These images will be used for both attenuation correction and registration of the serial image set. The initial PET brain scan will be acquired up to about 24 hours post injection. Based upon the discretion of the physician, non-surgical patients have the possibility of a second scan and third up to about 48 hours post injection. The times per bed position may be adjusted after the first patient is imaged, and his/her scans evaluated. Additional low dose CT scans will be performed at the image session for attenuation correction and image registration. PET study may be done on a PET-MR scanner for ease.

Other: - Blood and Urine samples

Venous blood and urine samples will be obtained at approximately 0.5 hours post injection at the end of each scan
