Safety of 68Ga-DOTA-tyr3-Octreotide PET in Diagnosis of Solid Tumors

Description:

This protocol is designed to test the efficacy of 68Ga-DOTATOC PET/CT in diagnosis, staging, and measurement of response to treatment in patients with somatostatin receptor positive tumors. Goals are to 1) compare this unique PET/CT scan with the current standard of care which is a combination of Octreoscan SPECT (single photon emission tomography) plus a high resolution, contrast enhanced CT; 2) Determine the sensitivity of 68Ga-DOTATOC PET/CT in diagnosis of patients with suspected somatostatin receptor positive tumor; and 3) For those patients who have had recent treatment (e.g., surgery, chemotherapy, targeted therapy such as anti-angiogenics, kinase inhibitors, peptide receptor radiotherapy), this scan will be used to measure response to treatment. These studies will be obtained with the long term goal of submitting a New Drug Application (NDA) for FDA approval of 68Ga-DOTATOC PET/CT in adults and children.

Isotope(s):
Target(s):
  • SSTR2
Ligand Class: Peptides
Chelator: DOTA
Inclusion
  • * Signed informed consent
  • Karnofsky performance status or Lansky Play Scale status of greater than 50 (or ECOG/WHO equivalent)
  • Known or suspected somatostatin receptor positive tumor such as carcinoid; neuroendocrine tumor; neuroblastoma; medulloblastoma; pheochromocytoma. Supporting evidence may include MRI, CT, biochemical markers, and or pathology report.
  • Age greater than or equal to 2 years
  • Subject is male; or is a female who is either pre-menarchal, surgically sterile (has had a documented bilateral oophorectomy and/or documented hysterectomy), postmenopausal (\> 1 years without menses), non-lactating, or of childbearing potential for whom a serum pregnancy test (with the results known prior to investigational product administration) is negative. A negative serum pregnancy test will be required for all female subjects with child bearing potential. If a false pregnancy test is suspected, e.g., perimenopausal condition, an obstetrician will be consulted to determine if she is/is capable of becoming pregnant.
Exclusion
  • Inability to complete the needed investigational and standard-of-care imaging examinations due to other reasons (severe claustrophobia, radiation phobia, etc.)
  • Inability to lie still for the entire imaging time (e.g. cough, severe arthritis, etc.)
  • Does the subject have any additional medical condition, serious intercurrent illness, or other extenuating circumstance that, in the opinion of the Investigator, may significantly interfere with study compliance?
  • * Subject weighs more than 400 pounds (Subjects who weigh more than 400 pounds will not be able to fit inside the imaging machines).
