Information provided by (Responsible Party):
GE Healthcare
  Purpose
To determine the level of association between the quantitative estimates of brain uptake of [18F]flutemetamol and the quantitative immunohistochemical and histochemistry estimates of amyloid levels in frontal lobe biopsy samples obtained from subjects during shunt placement for NPH.

Condition Intervention Phase
Normal Pressure Hydrocephalus Drug: [18F]Flutemetamol Phase 3

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: A Principal, Prospective, Open-label Biopsy Study to Validate Detection of Cerebral Cortical Amyloid With Flutemetamol (18F) Injection in Normal Pressure Hydrocephalus (NPH) Subjects.

Further study details as provided by GE Healthcare:

Primary Outcome Measures:
  • Standard Uptake Value Ratio (SUVR) at the Site of the Biopsy Based on the "Cerebellum" (CER) as the Reference Region. [ Time Frame: Post flutemetamol Injection ]
    The level of association between the quantitative estimates of brain uptake of [18F]flutemetamol and the quantitative immunohistochemical estimates of amyloid levels in biopsy samples obtained during shunt placement in patients who have Normal Pressure Hydrocephalus (NPH). The quantitative estimates of brain uptake of [18F]flutemetamol (SUVR) will be made from the analysis of PET images.


Secondary Outcome Measures:
  • Standard Uptake Value Ratio (SUVR) at the Site of the Biopsy Based on the "Pons" as the Reference Region. [ Time Frame: Post flutemetamol administration ]
    The level of association between SUVR and the quantitative estimates (area percents) of amyloid levels for the following regions: Biopsy site and Contralateral and Composite Regions.


Enrollment: 12
Study Start Date: March 2010
Study Completion Date: April 2011
Primary Completion Date: April 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm 1 Drug: [18F]Flutemetamol
All subjects will receive an IV dose of [18F]flutemetamol (less than 10 mg flutemetamol). The nominal activity of a single administration of [18F]flutemetamol will be 185 MBq.
Other Names:
  • Flutemetamol
  • AH110690
