Wuling Powder for the Treatment and Underlying Mechanism of Depressive Symptoms in Patients With Parkinson's Disease

June 20, 2017 updated by: Wen Su, Beijing Hospital

Wuling Powder for the Treatment and Underlying Mechanism of Depressive Symptoms in Patients With Parkinson's Disease: a Randomised, Double-blind, Placebo-controlled Trial.

Depression is one of the most important nonmotor features of idiopathic PD（Parkinson's disease ）which may not just interfere with the motor symptoms of PD but can also cause immense personal suffering as well as decreased quality of life with increased disability and caregiver burden. However,there is little hard evidence to guide clinical treatment. Although some newer dopamine agonists also have antidepressive effect, the use of tricyclic or nontricyclic antidepressants is frequently required.However, the side-effects of these agents may also worsen some preexisting nonmotor problems in PD. Wuling powder is a Chinese medicine which is made by cultivating Xylariasp mycelium using submerged fermentation technology. Xylariasp is the fungus sclerotia which grow in termite nests. Wuling powder is mainly used to soothe nerves and anti-insomnia in clinical. The antidepressant effect of Wuling powder has been confirmed in clinical, but not in the patients of Parkinson's disease. Therefore, the investigators design a randomized, double-blind, placebo-controlled study to evaluate the antidepressant effect of Wuling powder in PD patients and its underlying mechanism.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
