| Editor’s E-Note |
Researchers have developed a new technique allowing them to measure the brain’s blood flow and pinpoint the blood level of the drug necessary to affect specific regions of the brain. It uses a type of perfusion MRI called arterial spin labeling that measures the brain’s blood flow via MRI scans. The technique may be able to speed the development of new drugs and allow researchers to accurately determine whether established drugs are working.
Using brain scans to show the effects of a Parkinson’s drug, researchers at Washington University School of Medicine in St. Louis showed that the drug SYN115, when combined with levodopa, may be a viable therapy to treat Parkinson’s disease patients.
The potential for shortening the time it takes for new drugs to get to market, suggested by the study results, is notable. The implications for the treatment of Parkinson’s disease, and possibly other diseases, are certainly promising.

Brain Scans Show Effects of Parkinson's Drug
Neuroscientists using a new brain imaging technique could see an investigational drug for Parkinson’s disease get into a patient’s brain and affect blood flow in several key structures, an indicator the drug may be effective. The study, published in The Journal of Neuroscience, represents the first use of the technique in humans—called perfusion MRI—to test a drug still in development, according to the lead investigator. In the future, similar brain scans could speed the development of new drugs and help clinicians determine whether established drugs are working, according to the researchers at Washington University School of Medicine in St. Louis.
Perfusion MRI allowed the researchers to measure blood flow in the brain and even determine the precise blood level of the drug, SYN115, needed to affect particular regions of the brain. They were able to demonstrate that the drug may be a viable therapy when combined with levodopa, currently the most effective treatment for patients with Parkinson’s disease.
 The study, a phase 2 clinical trial, used two doses of the investigational drug. Its safety already had been tested in healthy volunteers. The goal was to determine what might be a reasonable dose for a larger clinical trial in Parkinson’s disease.
