Functional Status and Quality of Life

Detailed description: The study will enroll 336 participants in this multi-center study at approximately 56 sites across the US and Canada. In this study, we are comparing 10 mg of Isradipine to Placebo for treatment of newly diagnosed PD patients. Isradipine has been approved by the Food and Drug Administration (FDA) to treat high blood pressure but is considered investigational in this study, as it has not been approved for use in patients with PD. Isradipine can affect the function of specialized channels that are present in the types of brain cells that are affected in PD patient. These cells are usually responsible for making dopamine, which is depleted in patients with PD. Isradipine may block the damage caused by the flow of certain chemicals through these channels. Laboratory data has showed that Isradipine may prevent the development of Parkinson-like symptoms in animal studies. Isradipine has been evaluated in some patients with PD. The first study with isradipine controlled release (CR) in patients with early PD and normal blood pressure found that the drug was reasonably well tolerated and safe. The controlled release formulation of isradipine is not available for use and therefore this study is using the immediate release formulation. Eligible participants will be followed for up to 36 months and will be expected to complete 12 in-person visits and 4 telephone visits. The study visits will include clinical assessment of motor, neuropsychiatric and cognitive testing as well as collection of blood and urine samples. Study drug will taken twice daily, in the morning and in the evening with or without food. Prior to taking study drug, study participants will be required to take their blood pressure with a home blood pressure device provided to them for use in this study.


Minimum age: 30 Years. Maximum age: N/A. Gender(s): Both.


Inclusion Criteria:

- Subjects with early idiopathic PD (presence of at least two out of three cardinal

manifestations of PD). If tremor is not present, subjects must have unilateral onset and persistent asymmetry of the symptoms

- Age equal or greater than 30 years at the time of diagnosis of PD

- Hoehn and Yahr stage less than or equal to 2

- Diagnosis of PD less than 3 years.

- Currently NOT receiving dopaminergic therapy (levodopa, dopamine agonist or MAO-B

inhibitors) and NOT projected to require PD symptomatic therapy for at least 3 months from the baseline visit

- Use of amantadine and/or anticholinergics will be allowed provided that the dose is

stable for 8 weeks prior to the baseline visit

- If subject is taking any central nervous system acting medications (e. g.,

benzodiazepines, antidepressants, hypnotics) regimen must be stable for 30 days prior to the baseline visit

- Women of childbearing potential may enroll but must use a reliable measure of

contraception and have a negative serum pregnancy test at the screening visit Exclusion Criteria:

- Subjects with a diagnosis of an atypical Parkinsonism

- Subjects unwilling or unable to give informed consent

- Exposure to dopaminergic PD therapy within 60 days prior to baseline visit or for

consecutive 3 months or more at any point in the past

- History of clinically significant orthostatic hypotension or presence of orthostatic

hypotension at the screening or baseline visit defined as greater than or equal to 20 mmHg change in systolic BP and greater than or equal to 10 mmHg change in diastolic BP from sitting position to standing after 2 minutes, or baseline sitting BP less than 90/60

- History of congestive heart failure

- Clinically significant bradycardia

- Presence of 2nd or 3rd degree atrioventricular block or other significant ECG

abnormalities that in the investigator's opinion would compromise participation in study

- Clinically significant abnormalities in the Screening Visit laboratory studies or ECG

- Presence of other known medical or psychiatric comorbidity that in the investigator's

opinion would compromise participation in the study

- Prior exposure to isradipine or other dihydropyridine calcium channel blockers

within 6 months of the baseline visit

- Subjects on greater than 2 concomitant antihypertensive medications. If a history of

hypertension, then a maximum of 2 other antihypertensive agents will be allowed provided that the dosages of concomitant anti HTN therapy can be reduced/adjusted during the study based on the BP readings in consultation with the subject's primary care provider or cardiologist. Use of any concomitant calcium channel blockers will not be allowed from the baseline visit and for the duration of the study

- Use of grapefruit juice, ginkgo biloba, St. John's wort or ginseng will be prohibited

starting from the screening visit and for the duration of the study (as they interfere with the metabolism of isradipine)

- Use of clarithromycin, telithromycin and erythromycin will be prohibited starting

from the screening visit and for the duration of the study as the combination of clarithromycin, telithromycin or erythromycin and calcium channel blockers has been reported to be associated with increased risk of kidney and heart injury

- Presence of cognitive dysfunction defined by a Montreal Cognitive assessment (MoCA)

score of less than 26 at screening

- Subjects with clinically significant depression as determined by a Beck Depression

Inventory II (BDI) score greater than 15 at the screening visit

- History of exposure to typical or atypical antipsychotics or other dopamine blocking

agents within 6 months prior to the baseline visit

- History of use of an investigational drug within 30 days prior to the screening visit

- History of brain surgery for PD

- Allergy/sensitivity to isradipine or its matching placebo or their formulations

- Pregnant or lactating woman
