Clinical Trial Summary

Clinical study to demonstrate an at least equivalent performance of a new PET molecular Imaging radiopharmaceutical named [18F] LBT-999 in brain imaging compared to the SPECT reference method named [123I]-FP-CIT to establish the differential diagnosis between Parkinson's Disease and Essential Tremor.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Sensitivity and specificity by visual analysis	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.	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.
