NCT ID NCT02659956

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 follows 250 adults with multiple sclerosis (or similar conditions) for years, using yearly MRI scans and other tests to track brain and spinal cord changes. After a participant passes away, researchers examine donated brain and spinal cord tissue to see how the MRI findings match actual damage. The goal is to better understand how MS progresses and to improve future diagnosis and treatment.

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 study could reveal how MS damages the brain and spinal cord over time, pointing toward better ways to track and treat the disease.
What could go wrong
This is an observational study, not a treatment trial. It requires participants to agree to autopsy, which may limit enrollment. Results may take many years to emerge.

Show the full entry requirements

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

* INCLUSION CRITERIA: * Diagnosis of MS according to consensus criteria at the time of enrollment OR diagnosis of a disease that shares clinical, imaging, or biological features with MS OR individuals without known CNS disease. * Age greater than or equal to 18. * Able to participate in study procedures and provide high-quality clinical research data (for example, prior MRI scans show ability to tolerate the MRI scan with minimal motion artifact). * Willing to return to NIH for follow-up visits approximately annually (or every 5 years for non-CNS controls) until the time of autopsy. Note: participants who become too sick to return to NIH will not be removed from the study. * Willing to undergo autopsy with donation of at least the brain, spinal cord, and retinas. * Able to provide informed consent at the time of initial study enrollment and willing to appoint a Durable Power of Attorney (DPA) if an advanced directive is not already in place. * Except for non-CNS controls, simultaneously participating in another screening or natural history protocol within the NINDS Neuroimmunology Clinic at the time of study entry. * Eligible NIH employees and staff may participate. EXCLUSION CRITERIA: Unwilling to allow sharing and/or use in future studies of coded samples and data that are collected for this study.
