This study assesses dopamine transporter density using single photon emission computed tomography (SPECT) brain imaging with an investigational radiopharmaceutical, [123I]ß-CIT, in research participants with Parkinson's disease.

Condition Intervention Phase
Parkinson's Disease Parkinsonian Syndrome Procedure: [123I]ß-CIT and SPECT imaging Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Dynamic SPECT Imaging With [123I]ß-CIT in Patients With Parkinsonism

Further study details as provided by Institute for Neurodegenerative Disorders:

Primary Outcome Measures:
  • CIT uptake: measurement of dopamine transporter density compared with the clinical severity of illness

Secondary Outcome Measures:
  • Measurement of variability of strital uptake of [123I]ß-CIT when more than one scan has occurred

Estimated Enrollment: 500
Study Start Date: September 1992
Estimated Study Completion Date: August 2005
Detailed Description:

The brain imaging is conducted at the Institute for Neurodegenerative Disorders in New Haven, Connecticut. The imaging procedure occurs over a two day period.

After a screening visit, including review of the potential subject's neurological history and a thorough neurologic exam, subjects are injected with [123I]ß CIT, an investigational radioactive material that localizes in the brain.

Twenty-four hours later study participants return to the Institute for Neurodegenerative Disorders where an investigational scanning procedure is used to obtain SPECT (single photon emission computed tomography) images of the brain.
