A Randomized, Controlled, Double-Blind, Cross-over Study of Zolpidem for Patients With Parkinson's Disease
Levodopa treatment is associated with long-term complications. Dopamine deficiency is
associated with abnormal activity in certain parts of the brain. Zolpidem may change this
abnormal activity and, by doing so, may work in a different way than levodopa to help
parkinsonism.
The working hypothesis for this aim is that ZLP is superior to placebo in acutely improving
motor symptoms of PD. The investigators will conduct a randomized,controlled, double-blind,
cross-over study in 40 patients with PD. Each patient will receive placebo, levodopa and 2
doses of ZLP in a randomized order on 4 different occasions, about one week apart.
Inclusion Criteria:
- Subjects will have Idiopathic Parkinson's disease according to diagnostic criteria of
the United Kingdom Parkinson's Disease Society Brain Bank.
- Subjects will be capable and willing to provide written informed consent prior to
participation.
- Subjects will be ambulatory (in ON- and OFF-states) men and women, between the ages
of 30 and 75 years.
- Subjects will be on levodopa therapy, with a good response and indisputable motor
fluctuations.
- All other PD medications are allowed.
- Subjects will be on a stable regimen of PD medications for 2 weeks prior to
screening.
- Subjects will be required to come with a caregiver who can accompany the subject
to/from each study visit. Note: Subjects will not be allowed to drive home.
- Female subjects will be advised to use adequate birth control throughout the study as
the effects of ZLP on the fetus are unknown. Adequate birth control methods include
surgical sterilization, a partner who has had a vasectomy, oral contraceptives,
condom plus spermicidal cream/jelly, cervical cap plus spermicidal cream/jelly,
diaphragm plus spermicidal cream/jelly, or intrauterine device (in place for at least
3 months) plus spermicidal cream/jelly. Abstinence is considered an acceptable
contraceptive regimen. If a subject becomes pregnant during the study, it is
important that they contact the study physician immediately.
Exclusion Criteria:
- Neurodegenerative diseases.
- Tremor predominant PD, with a score of > 2 in more than one body part.
- Inability to tolerate being off levodopa for 12 hours.
- A score on the Montreal Cognitive Assessment (MoCA) of less than 26.
- Pregnancy or lactation.
- History of drug or alcohol abuse.
- Known or suspected sensitivity to the investigational study drugs.
- Other known medical or psychiatric condition that may compromise participation in the
study or that judged by the site investigator could disqualify a subject from
entering the study.
- Participation in another investigational drug study whereby they received
experimental drug < 30 days prior to start of this study.
- Subjects who have undergone surgical procedures for PD but otherwise meet inclusion
criteria will not be excluded a priori but evaluated on an individual basis.
