NCT04386317
Terazosin Effect on Cardiac Changes in Early Parkinson's Disease
Parkinson's disease (PD) is characterized by many non-motor symptoms that occur several years before the diagnosis, in particular idiopathic REM behavior disorder (iRBD), which is associated with autonomic impairment. The purpose of this study is to investigate the effect of treatment with the selective post-synaptic a1-adrenergic blocker terazosin on 123I-MIBG myocardial uptake in a population of subjects with defined pre-motor PD risks (i.e. hyposmia and RBD) and abnormal baseline 123I-MIBG uptake, with or without 123I-Ioflupane uptake abnormality or PD motor symptoms. Scintigraphic changes will be correlated to motor and non-motor severity of PD, measured by validated clinical scales and cardiac autonomic function tests.

Terazosin and Parkinson's Disease Extension Study
The purpose of this study is to investigate the long-term effects of treatment with the selective post-synaptic a1-adrenergic blocker terazosin on serial in a population of subjects with defined pre-motor Parkinson's disease (PD) risks and abnormal imaging exams. Imaging changes will be correlated to the presence and severity of motor and non-motor symptoms of PD, measured by validated clinical scales and cardiac autonomic function tests.
