- History of definite encephalitis (≥1 episode of confirmed encephalitis with objective residual neurologic deficit).
- The participant 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- The participant is using Chinese traditional medicine for PD treatment, which cannot be safely withdrawn for at least 1 week (7 days) before the imaging visit.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 participant 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 participant has a moderate to severe hepatic impairment (bilirubin >2x ULN and alanine aminotransferase (ALT) or aspartate aminotransferase (AST)>3x ULN).
- The participant has a history of current abuse of drugs and/or alcohol (for the previous 12 months before trial enrolment).
- The participant has a history of occupational exposure to any radiation >50 millisievert/year (mSv/year).
- The participant 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 participant presents with symptoms suggestive of corticobasal degeneration or Huntington's disease.
- The participant has known allergies to the investigational medicinal product (IMP).
- The participant 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 participant complains of claustrophobia.
The participant 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 participants with ET:
The participant has at least 1 first-degree relative diagnosed with PD.
For Healthy Volunteers:
History of psychiatric illness.
For all participants:
- It is the physician's best judgment not to include the participant in the trial.

Intervention / Treatment |
---|---|
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.
|
All participants (Participants with PS, ET, and HV) received a single dose of DaTSCAN™ ioflupane (123I) injection within the range of 111 to 185 megabecquerel (MBq) (3 to 5 millicurie [mCi]) per participant at a maximum volume of 5 milliliter [mL]) intravenously on Day 1.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Sensitivity Analysis of the Blinded Independent Read of DaTSCAN™ SPECT Images
Time Frame: At Day 1
|
Sensitivity was defined as positive percentage agreement and calculated as the number of true positives (TP) / (number of TP + number of false negatives [FN]): TP/(TP + FN), and a 2-sided 95% binomial confidence interval constructed around it.
Only the participants with a clinical diagnosis of PS were included in the sensitivity analysis.
The sensitivity 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 was used as the standard of truth, were summarized with by reader.
Each participant's SPECT image was read by 3 blinded readers.
|
At Day 1
|
Specificity Analysis of the Blinded Independent Read of DaTSCAN™ SPECT Images
Time Frame: At Day 1
|
Specificity was defined as negative percentage agreement and calculated as the number of true negatives (TN) / (number of TN + number of false positives [FP]): TN/(TN + FP), and a 2-sided 95% binomial confidence interval constructed around it.
For the specificity analysis, only participants with a clinical diagnosis of ET were included; the HVs were excluded from this analysis.

Measure Description |
Time Frame |
---|---|---|
Normalized DaTSCAN™ Uptake Based on Region Of Interest (ROI) With Central Read (by Semi-quantitative Assessment by Use of DaTQUANT™) of DaTSCAN™ SPECT Images
Time Frame: At Day 1
|
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 was performed with DaTQUANT™.
|
At Day 1
|
Number of Participants With Treatment-emergent Adverse Events (TEAEs), and Serious TEAEs
Time Frame: From start of study drug administration up to Day 4
|
An adverse event (AE) was any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this investigational product (IP) or medicinal product.
A Serious Adverse Event(SAE) was any untoward medical occurrence that at any dose met one, more of the following criteria: results in death, life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent, significant disability/incapacity, a congenital abnormality/birth defect, an important medical event.
A TEAE was any event emerging or manifesting at or after the initiation of treatment with an IP or medicinal product or any existing event that worsens in either intensity or frequency following exposure to the IP or medicinal product.
Number of participants with TEAEs and serious TEAEs were reported.
