Further study details as provided by University of Florida:

Primary Outcome Measures:
  • Identification of Human GBM CD Antigen Signature. [ Time Frame: 3 Years ] [ Designated as safety issue: No ]
    Already established and stored GBM cell lines will be screened for CD antigens to confirm that a selective cell surface antigen can be identified.


Secondary Outcome Measures:
  • Identification & Isolation of Human GBM Cells in Seeded Normal Control Human Blood. [ Time Frame: 3 Years ] [ Designated as safety issue: No ]
    Frozen and fresh human blood will be seeded with human GBM cells from established stored GBM cell lines and subjected to antibody-based cell identification and isolation procedures.

  • Prospective Isolation of GBM Tumor Cells in GBM Patient Blood. [ Time Frame: 3 Years ] [ Designated as safety issue: No ]
    Circulating tumor cells will be isolated from blood drawn from GBM patients.

  • Prospective Evaluation of the Routine Medical History of GBM Patients. [ Time Frame: 3 Years ] [ Designated as safety issue: No ]
    Medical records of GBM patients will be used to determine how circulating tumor cells impact outcome.


Estimated Enrollment: 170
Study Start Date: October 2009
Estimated Study Completion Date: August 2013
Estimated Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
GBM Patients
GBM Patients with a histologically confirmed or suspected diagnosis of glioblastoma multiforme.
Other: GBM Patients
2 teaspoons of blood will be collected during select clinic visits.
Other Name: GBM Patients
Normal Controls
Normal Controls will be adult volunteers who identify themselves as not having been diagnosed with a glioblastoma multiforme.
Other: Normal Controls
2 teaspoons of blood will be collected once.
Other Name: Normal Controls

Detailed Description:

Despite aggressive therapies, Glioblastoma Multiforme (GBM) is rapidly fatal. GBMs are increasingly recognized for occasionally metastasizing through the peripheral blood to distant locations. This research study involves the detection and novel characterization of human GBM (hGBM) circulating tumor cells (CTCs) within the peripheral blood of brain tumor patients by identifying their unique cell surface antigen profile, determining an optimal isolation protocol, and quantitatively and qualitatively reporting the yield and characteristics.
