Study Endpoints

Primary Endpoints

Sensitivity and specificity by visual analysis
The independent review committee will analyse the PET and SPECT images blindly. These analyses will be done by batch of 25 patients. Outcome will be assessed at the end of the study, an average of 2 years after first patient in.

Sensitivity and specificity of each imaging method on the diagnosis of normal or pathological examination on the visual analysis by 5 independent readers interpreting a minimum of 200 \[123I\]-FP/CIT SPECT per year, without knowing the clinical diagnosis.

Frequently asked questions about SPECT

What is SPECT used for in Parkinson Disease?

SPECT is a small molecule imaging agent under development by GE HealthCare Technologies Inc. for use in Parkinson Disease. It is being studied to help distinguish between Parkinson's Disease and Essential Tremor. The drug is currently in Phase 3 clinical development and remains investigational, not yet approved.

What does SPECT target?

SPECT is a small molecule imaging agent that targets the dopamine transporter in the brain. It is designed to be used with positron emission tomography (PET) imaging to help differentiate Parkinson's Disease from Essential Tremor. The drug is being developed by GE HealthCare Technologies Inc.

Who makes SPECT?

SPECT is being developed by GE HealthCare Technologies Inc., which trades under the ticker GEHC. The company is conducting clinical trials to evaluate the drug for use in Parkinson Disease. SPECT is currently in Phase 3 development as an investigational imaging agent.

What phase is SPECT in?

SPECT is currently in Phase 3 clinical development. It is an investigational small molecule imaging agent being studied for use in Parkinson Disease. The drug has completed one Phase 3 trial and is not yet approved by regulatory authorities.

What clinical trials is SPECT in?

SPECT has one completed Phase 3 clinical trial, NCT04265209, which enrolled 152 participants. The study compared [18F] LBT-999 PET to [123I]-FP/CIT SPECT to distinguish between Parkinson's Disease and Essential Tremor. The trial was conducted in France and included patients aged 35 years and older.
