The Global Outcome Combined Information on Change From Baseline in Schwab England Activities of Daily Living, 39-Item Parkinson's Disease Questionnaire, Ambulatory Capacity, Symbol Digit Modalities, and Modified Rankin at 5 Years. [ Time Frame: Change from baseline to 5 YEARS ]
All outcomes were coded such that higher scores indicated worse outcomes. Patients were ranked on each outcome and their ranks were summed (summed-ranks). Higher summed ranks (range, 5-4775) indicate worse outcomes. The mean summed ranks were compared by treatment group by a global statistical test (GST).
using a global statistical test this study will compare disease progression at 5 years between the creatine and placebo groups.

NET-PD LS-1 Creatine in Parkinson's Disease
A Multicenter, Double-Blind, Parallel Group, Placebo Controlled Study of Creatine in Subjects With Treated Parkinson's Disease (PD) Long Term Study (LS-1)
The purpose of this trial is to determine if the nutritional supplement creatine slows the progression of Parkinson's disease over time.

Parkinson's disease (PD) affects nearly a million Americans, a number that will increase over the coming decades as the population ages. Symptoms of PD may include tremor, rigidity or stiffness of the limbs and trunk, slowness of movement, and impaired balance and coordination. These problems occur because as PD worsens, some of the brain cells that control body movement die.

This study will determine if creatine——an investigational compound——is able to slow the progression of PD. Creatine, a widely used dietary supplement is thought to improve exercise performance. In animal models and human studies, creatine has been shown to be well tolerated and may have some ability to protect brain cells.

In the NET-PD LS-1 study, 1,720 participants will be randomly assigned to receive either creatine or a placebo (inactive substance). Participation in this study lasts a minimum of 5 years and includes at least 9 follow-up clinic visits and at least 3 telephone calls.

Inclusion Criteria:

  • Willing and able to give informed consent and willing to commit to long-term follow-up
  • PD (asymmetric features including slowness (bradykinesia) plus resting tremor and/or rigidity) within 5 years of diagnosis
  • Treated/responsive to dopaminergic therapy (dopamine agonists or levodopa) for at least 90 days, but not more than 2 years.

Exclusion Criteria:
