February 18, 2016 updated by: Rajesh Pahwa, MD, University of Kansas Medical Center

A Pilot Double-Blind, Parallel Group, Placebo Controlled Study of Oxaloacetate in Subjects With Treated Parkinson's Disease (PD)

The purpose of this study is to determine if Oxaloacetate (OAA) is a safe and effective treatment for Parkinson's disease. Each subject will be asked to make 3 study visits and complete two safety follow-up phone calls over a 4 month period.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

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.

Ages Eligible for Study

30 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Able to give informed consent and follow instructions per the protocol
  • Diagnosis of idiopathic PD within 7 years of diagnosis
  • Taking stable doses of levodopa and would not predictably need adjustment in PD medications for 4 months
  • Unified Parkinson's Disease Rating Scale (UPDRS) II + III at least 30 points at baseline

Exclusion Criteria:

  • Previously taken Oxaloacetate
  • Participation in other drug studies or use of other investigational products within 30 days prior to baseline
  • In the Investigator's opinion, any unstable or clinically significant condition that would impair the subjects' ability to comply with study follow-up
  • Other known or suspected cause of parkinsonism

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Unified Parkinson's Disease Rating Scale (UPDRS) Total Score
Time Frame: 4 months
The UPDRS has 3 subscales including Mentation (4 questions based on patient report with answers on a scale of 0-4, with a total of 16 points), Activities of Daily Living (13 questions based on patient report with answers on a scale of 0-4, with a total of 52 points) and Motor (27 questions based on clinician assessment on a scale of 0-4, with a total of 108 points). The total scores represents the sum of each of these sections for a total of 176 points with a higher score representing greater dysfunction.
4 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Unified Parkinson's Disease Rating Scale (UPDRS) ADL + Motor Score
Time Frame: 4 months
The UPDRS has 3 subscales including Mentation (4 questions based on patient report with answers on a scale of 0-4, with a total of 16 points), Activities of Daily Living (13 questions based on patient report with answers on a scale of 0-4, with a total of 52 points) and Motor (27 questions based on clinician assessment on a scale of 0-4, with a total of 108 points). This measure examined the ADL + Motor subscales which have a total of 160 points with a higher score representing greater dysfunction.
4 months
Parkinson's Disease Questionnaire - 39 (PDQ-39)
Time Frame: 4 months
The PDQ-39 is a measure of quality of life in Parkinson's disease patients. It has 39 questions each with a response from 0-4 for a total of 156 points. The total score is calculated as a percentage so the scores of the 39 items are added and divided by 156 and multiplied by 100. The higher the score the worse quality of life.
4 months
Montreal Cognitive Assessment (MoCA)
Time Frame: 4 months
The MoCA is an assessment of cognitive function. The total possible score ranges from 0 to 30 points with a lower score representing greater cognitive impairment.
4 months
Geriatric Depression Scale (GDS)
Time Frame: 4 months
The GDS is a measure of depression. The scale has 30 yes/no questions. Each question has a maximum score of 1 and a total possible score ranging from 0 to 30. The higher the score the greater the depression.
4 months
NonMotor Symptom Questionnaire (NMSQuest)
Time Frame: 4 months
The NMSQuest is a 30 item questionnaire with 30 yes/no questions. There is a total of 30 points with each "yes" score representing 1 point and therefore the higher the score the greater number of nonmotor symptoms present. The score can range from 0 to 30.
