Two Separate But Identical Studies Evaluating the Safety and Efficacy of ALTROPANE® in the Use of SPECT Imaging for Upper Extremity Tremor
United States240 participantsStarted 2010-07
Plain-language summary
This will be two separate but identical studies: ALSE-A-02a, ALSE-A02b. Each study is designed to evaluate the diagnostic accuracy and safety of a single dose of 123I-ALTROPANE® in subjects with upper extremity tremor for less than three years. Currently, no radiopharmaceutical diagnostic imaging agent has been approved by the FDA in the U.S. for use in diagnosing Parkinson disease and related Parkinsonian syndromes. The diagnosis of Parkinsonian syndromes in the U.S. is based on clinical criteria only. The goal is to demonstrate that 123I-ALTROPANE® paired with SPECT imaging permits a more accurate early diagnosis of Parkinson disease than a clinical diagnosis by a general neurologist.

Exclusion criteria
. Any clinically significant acute or unstable physical or psychological illness based on medical history or physical examination at Visit 1, as determined by the PI;
. Any unexpected clinically significant abnormal laboratory or electrocardiogram (ECG) results obtained at Visit 1 and as determined by the PI;

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
To evaluate the diagnostic accuracy of a single dose of 123 I-ALTROPANE® as an imaging agent to aid in the diagnosis of Parkinsonian syndromes (PS) in subjects with upper extremity tremor for less than 2 years.
