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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether breathing short bursts of low-oxygen air (like at high altitude) can improve ankle strength and brain activity in people with multiple sclerosis. Twenty-one adults with relapsing forms of MS will undergo 15 cycles of low oxygen followed by normal air in one session. Researchers will measure muscle strength and use brain scans to understand how the intervention works.

What this could mean

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

Active substance
Acute Intermittent Hypoxia (AIH) - brief breathing of low oxygen air
What this could lead to
If it works, this could point toward a new way to improve strength in people with MS without drugs.
What could go wrong
This is a very small early study (21 people) looking at brain changes, not a proven treatment. The low-oxygen breathing may not lead to lasting strength gains.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 21 people

The number the study aims to enrol. It can still change while the study runs.

Started

Apr 2024

Expected to finish

Jan 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

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

Inclusion Criteria: * Diagnoses of relapsing form of MS (including relapsing-remitting MS and secondary-progressive MS) * Expanded Disability Status Scale (EDSS) score of at least 3 and no more than 6.5 * Motor Functional System Scale (FSS) between 2-4 * Relapse free for at least 1 year * Age ≥ 18 years and ≤ 75 years * Safe to be scanned based on MRI questionnaire * Participants using dalfampridine will be eligible if taking the same daily dose for at least 2 months prior to screening Exclusion Criteria: * Active contrast-enhancing MS lesions, or diffusion positive lesions suggestive of acute cerebrovascular disease on baseline MRI scan * Uncontrolled hypertension (Systolic between 85 and 140, diastolic between 90 and 55) * History of epilepsy * Chronic obstructive pulmonary disease * Uncontrolled Sleep apnea * Pregnancy
