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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 short, controlled sessions of breathing lower oxygen (called low oxygen therapy) can help stabilize 24-hour blood pressure in people with chronic cervical spinal cord injury. Ten participants will undergo 4 days of treatment, with blood pressure and heart function measured before and after. The goal is to see if this simple approach can reduce cardiovascular risk in this population.

What this could mean

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

Active substance
low oxygen therapy (intermittent hypoxia)
What this could lead to
If it works, this could point toward a non-drug way to improve blood pressure stability and reduce heart disease risk in people with spinal cord injury.
What could go wrong
This is a very small early-phase trial with only 10 participants, so results may not apply widely. The therapy involves controlled low-oxygen breathing, which may not be safe for everyone.

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

Inclusion Criteria: * Are between the ages of 19-65 * Living with a chronic cervical (at or above T1) spinal cord injury of at least one year * Are fluent in english Exclusion Criteria: * High-cervical injuries requiring ventilator assistance to breathe will be excluded on account of the necessity of the facemask for the delivery of hypoxia * Unhealed fracture, contracture, or pressure sore that might interfere with participants' ability to complete the protocol * Additional concurrent neurological conditions (e.g., multiple sclerosis, Parkinson disease, stroke or brain injury) * Uncontrolled cardiovascular or pulmonary disease * Severe neuropathic pain * Severe recurrent autonomic dysreflexia * History of seizure disorders * Known pregnancy
