What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study investigates the biological mechanisms behind young-onset Parkinson's disease, which begins before age 50. Researchers will analyze genetic tests and protein markers in spinal fluid and skin biopsies from 250 participants to identify distinct disease subtypes. The goal is to better understand why the disease develops earlier in some people and to find biomarkers that could help tailor future treatments and clinical trials.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this research could identify biological markers and genetic factors that help classify young-onset Parkinson's into subtypes, potentially guiding more personalized treatments and clinical trial design.
What could go wrong
This is an observational study, so it won't directly test a treatment. Findings may not lead to immediate clinical changes, and the biological markers studied may not prove to be reliable indicators across all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: YOPD cohort: 1. Male or female 18 years or older (inclusive) of any race and ethnicity 2. Diagnosis of Parkinson's disease (PD) confirmed by a movement disorder specialist and with an age of onset of less than or equal to the age of 50 years old 3. Willingness to undergo a skin punch biopsy LOPD cohort: 1. Male or female 18 years or older (inclusive) of any race and ethnicity 2. Diagnosis of PD confirmed by a movement disorder specialist and with an age of onset after the age of 50 years Healthy Control cohort: 1. Male or female 18 years or older (inclusive) of any race and ethnicity 2. Never been diagnosed with PD as reported by medical history and as assessed by study PI Exclusion Criteria: 1. Diagnosis of atypical parkinsonism (i.e. progressive supranuclear palsy, corticobasal degeneration, multiple system atrophy) or secondary parkinsonism (i.e. normal pressure hydrocephalus, drug-induced parkinsonism). 2. Clinical history of autoimmune or chronic inflammatory disorder or exposure to chronic immunosuppressant or immunomodulatory medications. 3. Pregnancy 4. Dermatological conditions that would prevent performing skin punch biopsies
