Parkinsonian Syndrome, Parkinson Disease(PD), Multiple System Atrophy (MSA)
About this trial
This is an interventional diagnostic trial for Parkinsonian Syndrome
Eligibility Criteria
Inclusion Criteria:
For all subjects:
Chinese male or female, aged 40 to 80 years, has agreed to sign and date the written informed consent form.
For Healthy Volunteers:
Non-patient volunteers with good age-appropriate health as established by clinical examination during screening and no evidence of movement disorder by complete neurological evaluation.
For patients with Parkinson's disease:
A diagnosis of clinically established or clinically probable PD in accordance with the MDS Clinical Diagnostic Criteria for Parkinson's Disease [Postuma et al. 2015].
For patients with MSA (SDD):
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):
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].
For patients with ET (no SDD):
- A diagnosis of definite or probable ET in accordance with the Washington Heights-Inwood Genetic Study of Essential Tremor (WHIGET) diagnostic criteria for ET (no SDD) [Louis et al. 1997].
Exclusion Criteria:
- The subject is lactating.
- The subject is pregnant as detected by a β-human chorionic gonadotropin (β-hCG) pregnancy test.
- A cerebral structural vascular abnormality indicative of at least 1 infarction in the region of the basal ganglia (including the internal capsule) ≥5 mm has been confirmed, preferably by magnetic resonance imaging (MRI) performed within 6 months of screening. If an MRI is not clinically feasible, cerebral CT imaging within 6 months is also acceptable.
- The subject is diagnosed with major neurocognitive disorder by the Diagnostic and Statistical Manual of Mental Disorders (DSM) 5 criteria, or Mini-Mental State Examination total score is <24.
- Subject is being investigated for or has been diagnosed and/or is being treated for repeated stroke with stepwise progression of Parkinson features.
- History of repeated head injury (≥3 concussions, or history of professional sports with repeated head trauma [e.g., boxing]).
- History of definite encephalitis (≥1 episode of confirmed encephalitis with objective residual neurologic deficit).
- The subject is using or has insufficient washout from medication known or suspected to interact with striatal uptake through direct competition with binding of DaTSCAN™ to the dopamine transporters (i.e., amphetamine, benztropine, bupropion, cocaine, mazindol, methylphenidate, phentermine, sertraline, selective serotonin reuptake inhibitors) before the imaging visit.
- The patient is using Chinese traditional medicine for PD treatment, which cannot be safely withdrawn for at least 1 week (7 days) before the imaging visit.
- The subject has a moderate to severe renal impairment (e.g., serum creatinine >1.5x upper limit of normal [ULN], blood urea nitrogen [BUN] >30 mg/dL).
- The subject has a moderate to severe hepatic impairment (bilirubin >2x ULN and alanine aminotransferase (ALT) or aspartate aminotransferase (AST)>3x ULN).
- The subject has a history of current abuse of drugs and/or alcohol (for the previous 12 months before trial enrolment).
- The subject has a history of occupational exposure to any radiation >50 mSv/year.
- The subject has been previously enrolled in this study or participated in a clinical study involving an investigational pharmaceutical product within 30 days prior to screening and/or any radiopharmaceutical within a minimum of 5 radioactive half-lives prior to screening.
- The subject presents with symptoms suggestive of corticobasal degeneration or Huntington's disease.
- The subject has known allergies to the investigational medicinal product (IMP).
- The subject presents with any clinically active, serious, life-threatening disease with a life expectancy of less than 12 months.
- Any laboratory value(s) exceeding the limits of normality if deemed to be clinically relevant by the investigator.
- The subject complains of claustrophobia.
The subject has a moderate to severe thyroid disease (thyroid stimulating hormone [TSH] exceeding the limits of normality by more than 10%), if deemed to be clinically relevant by the investigator.
For patients with ET:
The patient has at least 1 first-degree relative diagnosed with PD.
For Healthy Volunteers:
History of psychiatric illness.
For all subjects:
- It is the physician's best judgment not to include the patient in the trial.

Arm 1
Experimental
DaTSCAN™ ioflupane (123I) injection
Participants with Parkinsonian Syndrome (PS), Essential Tremor (ET), and Healthy Volunteers (HV) received a single dose of DaTSCAN™ ioflupane (123I) injection. Single photon emission computed tomography (SPECT) imaging was performed between 3 to 6 hours post-injection and lasted approximately 20 minutes to 1 hour.
