Pioglitazone in Early Parkinson's Disease

2015年9月15日 更新者:University of Rochester

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.

详细说明

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.

Change in Total Unified Parkinson's Disease Rating Scale (UPDRS) Score From Baseline to 44 Weeks
大体时间: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.

大体时间
Change in Ambulatory Capacity From Baseline to 44 Weeks
大体时间: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.

44 weeks
Change in Schwab and England Scale From Baseline to 44 Weeks
大体时间:44 weeks
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).
44 weeks
Change in Parkinson's Disease Questionnaire (PDQ-39) From Baseline to 44 Weeks
大体时间: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.

44 weeks
Change in the Mattis Dementia Rating Scale (DRS-2)From Baseline to 44 Weeks
大体时间:44 weeks
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.
44 weeks
Change in the 15-item Geriatric Depression Scale (GDS-15)From Baseline to 44 Weeks
大体时间: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.
