Pioglitazone in Early Parkinson's Disease
A Multi-Center, Double-Blind, Placebo-Controlled Phase II Study of Pioglitazone in Early Parkinson's Disease
This is a multi-center, double-blind, placebo controlled clinical trial of two dosages of oral pioglitazone (15 milligram(mg) and 45 milligram (mg)) for safety, tolerability, and futility.
Subjects who are on stable dose of rasagiline 1 mg/day or selegiline 10 mg/day for at least 8 weeks but no more than 8 months, will be randomized to one of two dosages of oral pioglitazone (15 mg and 45 mg) or matching placebo.
The study will measure disease progression by the change in total Unified Parkinson's Disease Rating Scale (UPDRS) score between the baseline visit and 44 weeks.

Descripción detallada
A Multi-Center, Double-Blind, Placebo-Controlled Phase II Study of Pioglitazone in Early Parkinson's Disease (PD). The patient population has early stage PD (< 5 years from diagnosis), must be treated with 1 mg/day of rasagiline or 10 mg/day of selegiline for at least 8 weeks but not more than 8 months prior to enrollment.
The primary objective of this clinical trial is to assess the futility of pioglitazone on PD disease progression as measured by the change in total UPDRS score between the baseline visit and 44 weeks. The secondary objectives of the study are to collect additional efficacy and safety/tolerability data to be used in planning a subsequent Phase III trial of pioglitazone in early, treated PD. Measures of cognition, mood and blood- and urine-based biomarkers will also be explored. Subjects in this trial are randomly assigned in a 1:1:1 ratio to one of three study arms: 15 mg, 45 mg or placebo.

Inclusion Criteria:
- Willing and able to give informed consent.
- Men and women with idiopathic PD of less than 5 years duration from diagnosis with a Hoehn and Yahr Stage < 2.
- On stable dosage of rasagiline 1 mg/day or selegiline 10 mg/day for at least 8 weeks but not more than 8 months prior to baseline. Expected to remain on stable dose of rasagiline or selegiline as the only treatment for their PD for the duration of the study (44 weeks).
- Diagnosis must be confirmed by bradykinesia plus one of the other cardinal signs (resting tremor, rigidity) being present, without any other known or suspected cause of parkinsonism. The clinical signs must be asymmetric.
- Subjects may be taking stable doses (30 days) of anticholinergics or creatine (< 5gm/day) but must be expected to remain on the same dose.
- Age > 30 years.
- Women who are not postmenopausal or surgically sterile must use a medically accepted contraceptive regimen for at least 60 days before the baseline visit, and agree to continue such use throughout the duration of the study and for 30 days after the final dose of study drug.
Exclusion Criteria:
- Exposure to dopaminergic PD therapy or amantadine within 60 days prior to baseline visit or for 90 days or more at any point in the past
- Use of any of the following drugs within 180 days prior to baseline: neuroleptics, metoclopramide, alpha-methyldopa, clozapine, olanzapine and flunarizine.

- Known history of osteoporosis. All women ≥ 65 years of age or men and woman at high risk of osteoporosis should have documented evidence of screening for osteoporosis. Factors associated with high risk of osteoporosis include: previous non traumatic fracture, chronic glucocorticoid use, body weight under 58 kg, family history of hip fracture, current cigarette smoking, and excessive alcohol intake.
- Drug or alcohol use or dependence that, in the opinion of the Investigator, would interfere with the safe conduct of the study.
- Significant peripheral edema (2+ or more) of the extremities of any etiology.
- Current or planned use of gemfibrozil or rifampin during the trial.

Change in Total Unified Parkinson's Disease Rating Scale (UPDRS) Score From Baseline to 44 Weeks
Periodo de tiempo: 44 weeks
|
Change in total UPDRS score from baseline to 44 weeks (in subjects treated with rasagiline 1 mg/day or selegiline 10 mg/day). The Total UPDRS is the sum of parts I, II, and III. The possible range of the total UPDRS is from 0-176. Higher values indicate worse outcomes. The change is 44 weeks - baseline. |

Change in Ambulatory Capacity From Baseline to 44 Weeks
Periodo de tiempo: 44 weeks
|
This is the sum of the 5 UPDRS questions regarding ambulatory capacity: falling, freezing, walking, gait, postural stability. Ambulatory Capacity is calculated as the sum of items 13-15, 29, 30 of the Unified Parkinson's Disease Rating Scale (UPDRS). It ranges from 0-20. Higher scores are worse. Change is 44 weeks - baseline. |

The modified Schwab and England Activities of Daily Living is a single question ranging from 0-100% with anchors for each 10% interval.
Higher scores are better (100% completely independent- 0% vegetative).

Periodo de tiempo: 44 weeks
|
The Parkinson's Disease Questionnaire (PDQ-39) is a short, 39 item measure of quality of life in subjects with Parkinson's disease. The questionnaire covers 8 aspects of quality of life: mobility, activities of daily living, emotional well-being, stigma, social support, cognitions, communication and bodily discomfort. The total score ranges from 0 (never have difficulty) to 100 (always have difficulty). Lower scores reflect better quality of life. |

The Mattis dementia rating scale is a psychometric instrument designed to assess the extent and nature of dementia.
Mattis Dementia Rating scale (DRS-2) raw score is the sum of 5 raw sub-scores (attention has possible 37 points, initiation/perseveration has possible 37 points, construction has possible 6 points, conceptualization has possible 39 points, memory has possible 25 points).
Total range is 0-144.
Higher scores are better.

Change in the 15-item Geriatric Depression Scale (GDS-15)From Baseline to 44 Weeks
Periodo de tiempo: 44 weeks
|
The Geriatric Depression Scale - 15 is a short 15 yes or no question instrument for assessing depression in the elderly.
It has been found to be particularly useful in assessing depression in Parkinson's Disease.
A score of 0 to 5 is normal.
A score greater than 5 suggests depression.
