National Institute of Neurological Disorders and Stroke (NINDS) Parkinson's Disease Neuroprotection Trial

Parkinson's Disease Clinical Trial

Official title: A Multi-center, Double-blind, Pilot Study of Minocycline and Creatine in Subjects With Early Untreated Parkinson's Disease

Status Completed

Clinical Trial Summary

The goal of this study is to assess the impact of minocycline and creatine on the progression of Parkinson's disease, in order to determine whether it is reasonable to proceed with further study of either of these agents.

Clinical Trial Description

Parkinson's disease (PD) affects nearly a million Americans, a number that will increase over the coming decades as the population ages. While available medical therapies are usually effective for controlling symptoms in the initial years following diagnosis, higher doses of multiple agents are required over time, with increasing side effects and incomplete control of symptoms. Although these treatments can dramatically improve the lives of patients with PD initially, they do not address the underlying causes of the disease or the inevitable disease progression.

This multi-center, randomized, double-blind trial will involve 42 trial centers in the United States and Canada, and enroll 195 people with PD. The primary objective of this neuroprotection trial is to identify agents capable of slowing the progression of PD. In the trial, investigators will assess the impact of minocycline and creatine on the progression of PD and determine if it is futile or non-futile to proceed with further study of these agents.

In this study, subjects with early, untreated PD will be equally randomized into one of the three study arms: 1.) the group that receives active minocycline and placebo instead of creatine, 2.) the group that receives active creatine and placebo instead of minocycline, or 3.) the group that receives placebo instead of minocycline and creatine. Subjects will remain on the blinded study drug for 18 months. ;
