简要总结
The influence of bupropion compared to placebo on the change of apathy as quantified by the apathy evaluation scale (AES-I, where I [informant] is a friend or family member familiar with the daily activities of the subject) in patients with HD after ten (10) weeks of treatment.
详细描述
The safety and tolerability of Bupropion in HD.
The influence of Bupropion compared to placebo on the:
- change of apathy as quantified by the AES-C (clinician) or the AES-S (self),
- change of motor symptoms (UHDRS) and quantitative grip force motor assessment,
- change of cognitive symptoms (UHDRS and MMSE),
- change of psychiatric symptoms (UHDRS, HADS),
- change of activities of daily living (UHDRS),
- change of the NPI caregivers' distress score (NPI-D),
- change of ventral striatal and ventromedial prefrontal activation in response to a reward paradigm as quantified by fMRI.

- •Exclusion criteria:
- •Pregnant or nursing women

- •Known hypersensitivity reaction associated with bupropion, gelatine, lactose or magnesium stearate
- •Clinically relevant abnormal findings in the ECG, the vitals, in the physical examination or laboratory values at screening that could interfere with the objectives of the study or the safety of the subject as judged by the investigator
- •Acute disease state (e.g. nausea, vomiting, fever, diarrhoea, infection) within 7 days of first dose
- •Definite or suspected personal history or family history of adverse reactions or hypersensitivity to the trial compounds (or to compounds with a similar structure)
