Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Intermittent normobaric hyperoxia (NBH) by increasing FiO2 to 100% for a duration of 4.5h (270 min), twice daily over five consecutive days. Instead of fixed 12-hour intervals between sessions, the two daily treatments will follow a pre-specified interval: a minimum of 1.5h (90min) between sessions for treatment B, and 10h (600min) for treatment A.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

Individual participant data (IPD) underlying the primary results of this study-including de-identified clinical, physiologic, and outcome variables-will be made available following publication of the main results. Data will be shared in accordance with institutional policies and applicable regulations after all direct identifiers have been removed using a standardized de-identification protocol. The curated dataset, accompanying data dictionary, and analytic code (when applicable) will be deposited in the National Spinal Cord Injury Statistical Center (https://sites.uab.edu/nscisc/), where they will be accessible under a controlled-access model. Qualified researchers may request access by submitting a brief proposal outlining the intended use of the data; requests will be reviewed by the study team to ensure scientific validity and compliance with participant privacy protections. Data will remain available for the duration required by institutional policy.
