What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Motor symptoms as assessed by the Movement Disorder Society's Unified Parkinson's Disease Rating Scale (MDS-UPDRS)

    Change from baseline in the MDS-UPDRS. The MDS-UPDRS contains 4 subscales: Part I, non-motor aspects of experiences of daily living (13 items); Part II, motor aspects of experiences of daily living (13 items); Part III, motor examination (33 scores based on 18 items); Part IV, motor complications (6 items). The rating for each item, or sub-item, is from 0 (normal) to 4 (severe). The total score for each Part is obtained from the sum of the corresponding item scores.

    Measured: 18 months

  2. MSA symptoms/signs as assessed by the Unified Multiple System Atrophy Rating Scale (UMSARS)

    Change from baseline in the Unified Multiple System Atrophy Rating Scale (UMSARS) and compared to placebo. UMSARS total scores range from 0-104 points with higher scores indicating greater severity of impairment.

    Measured: 18 Months

Secondary outcomes (2)
  1. Change in the quality of life as measured by Parkinson's Disease Questionnaire (PDQ-39)

    Change from baseline in the Parkinson's Disease Questionnaire (PDQ-39). PDQ-39 is a self-reported 39-item questionnaire designed to measure health related quality of life in Parkinson's Disease patients. It provides scores in 8 domains: mobility, activities of daily living, emotions, stigma, social support, cognitive function, bodily discomfort and communication, as well as a summary index score for quality of life.

    Measured: 18 months

  2. Change in the quality of life as measured by Multiple System Atrophy Quality of Life (MSA-QoL)

    Change from baseline in the Multiple System Atrophy Quality of Life (MSA-QoL) scale. MSA-QoL is a self-reported questionnaire that measures MSA impact in day to day activities. Scale consists of 40 items with a five response option format (0 - no problem to 4 extreme problem) and a "not applicable" response option.

    Measured: 18 months

Questions about this trial

What is this clinical trial studying?

An observational study of Parkinson's Disease and Multiple System Atrophy, Parkinson Variant, run by AskBio Inc at 11 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in United States, Poland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Motor symptoms as assessed by the Movement Disorder Society's Unified Parkinson's Disease Rating Scale (MDS-UPDRS) (time frame: 18 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jul 2026.
