Brief Summary:
This is a multicentre, comparator-group, open-label, controlled, nonrandomised clinical study to compare the SPECT findings after a single IV administration of DaTSCAN™ ioflupane (123I) injection for patients with a clinical diagnosis of PS (SDD; specifically, patients with PD [SDD], MSA [SDD] or PSP [SDD]) as compared with patients with a clinical diagnosis of ET (no SDD) and age-matched healthy controls.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 172 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: A Multicentre, Phase 3, Clinical Study to Compare the Striatal Uptake of a Dopamine Transporter Radioligand, DaTSCAN™ Ioflupane (123I) Injection, After Intravenous Administration to Chinese Patients With a Diagnosis of Parkinson's Disease, Multiple System Atrophy, Progressive Supranuclear Palsy, or Essential Tremor and to Healthy Controls
Actual Study Start Date : June 18, 2020
Actual Primary Completion Date : December 16, 2021
Actual Study Completion Date : December 16, 2021

Arm Intervention/treatment
Experimental: DaTSCAN™ ioflupane (123I) injection
Participants will receive a single intravenous (IV) injection of DaTSCAN™ (123I) ioflupane. Single photon emission computed tomography (SPECT) imaging will be performed between 3 to 6 hours post-injection and will last approximately 20 minutes to 1 hour.
Drug: DaTSCAN™ Ioflupane (123I) Injection
All participants will receive a single IV injection of DaTSCAN™ ioflupane (123I) into an arm vein. The dose of DaTSCAN™ ioflupane (123I) administered will contain a total of 3 to 5 mCi (111 to 185 MBq) in a maximum volume of 5 mL for an individual participant.
Other Name: Ioflupane (123I)

Primary Outcome Measures :
  1. • Assessment of DaTSCAN™ SPECT images by 3 independent blinded readers to compare specific striatal uptake with the clinical diagnosis. [ Time Frame: 1 Day ]
    The sensitivity and specificity of the Blinded independent read of DaTSCAN™ SPECT images in detecting or excluding striatal dopaminergic deficit (SDD), when the clinical diagnosis as established by the investigator is used as the standard of truth, will be summarised with both by-reader and majority-read analyses.

Secondary Outcome Measures :
  1. • Central read (by semi-quantitative assessment by use of DaTQUANT™) of DaTSCANTM SPECT images to compare specific uptake with clinical diagnosis. [ Time Frame: 1 Day ]
    A semi-quantitative analysis of the striatal uptake ratios in specific regions of interest (ROIs; i.e., left and right striatum, caudate, and putamen) of DaTSCAN™ SPECT images will be performed with DaTQUANT™.

  2. • Comparison and assessment of safety parameters and AEs reported by all study participants. [ Time Frame: 32 Days ]

    An overall summary of AEs and DaTSCAN™-emergent AEs will be presented, coded with Medical Dictionary for Regulatory Activities (MedDRA) and summarised by MedDRA system-organ class and preferred term.

    Observations and changes from baseline in the results of the physical examination (including vital signs blood pressure and heart rate), neurological examination, injection site monitoring, and clinical laboratory evaluations (haematology, serum biochemistry, and urinalysis) will be summarised.

    For patients with MSA (SDD):

  4. A diagnosis of probable or possible MSA in accordance with the Second Consensus Statement on the Diagnosis of MSA [Gilman et al. 2008].

    For patients with PSP (SDD):

  5. A diagnosis of probable or possible PSP in accordance with the Clinical Criteria for the Diagnosis of Progressive Supranuclear Palsy National Institute for Neurological Disorders and Society for PSP (NINDS-SPSP) [Litvan et al. 1996].
