Safety and Efficacy of DA-9805 for Parkinson's Disease

Parkinson's Disease Clinical Trial

Official title: A Phase IIa, Randomized, Multicenter, Double-Blind, Placebo-Controlled Study to Evaluate the Safety, Tolerability and Efficacy of DA-9805 in Subjects With Parkinson's Disease

Status Completed

Clinical Trial Summary

This is a phase IIa, first in human, randomized, double-blind, multicenter study to evaluate the safety, tolerability and efficacy of DA-9805 at 45mg, 90mg versus placebo in subjects diagnosed with early Parkinson's disease.

Clinical Trial Description

Parkinson's disease (PD) is recognized as one of the most common neurologic disorders, affecting approximately 1% of individuals older than 60 years. There are 2 major neuropathologic findings: the loss of pigmented dopaminergic neurons in the substantia nigra pars compacta (SNpc) and the presence of Lewy bodies.

Parkinson's disease affects an estimated 1.5 million persons in the United States, with over ten million affected worldwide, and these estimates are expected to increase substantially in the next few decades. Despite the increasing prevalence, the approved agents for the early management of Parkinson's disease have changed little in the past decade; however, there have been advances in drug delivery, dosing, and the use of combination therapy in an attempt to reduce adverse events. The most important, unmet medical need in targeting Parkinson's disease is developing agents with neuroprotective potential. So far, no drug has been shown to reduce or slow down the progression of PD.

DA-9805 is a botanical drug product composed of three main raw herbal materials. It is expected that DA-9805 will help treat PD by prevention of dopaminergic neurodegeneration via recovery of mitochondrial dysfunction, anti-inflammatory effect and relief from Endoplasmic reticulum (ER) stress and oxidative stress. ;
