Randomized, Double-Blind, Placebo-Controlled, Crossover Study of Trans Sodium Crocetinate in Healthy Volunteers Exercising at Altitude

April 12, 2022 updated by: Diffusion Pharmaceuticals Inc
This is a randomized, placebo-controlled, crossover study of Trans Sodium Crocetinate (TSC) in healthy volunteers, age 18-40 (inclusive), exercising at altitude. The primary objective is to determine the effect of (TSC) on partial pressure of oxygen (PaO2) and maximal oxygen consumption (VO2 max); the secondary objective is to assess the effect of TSC on oxygen saturation (SpO2).

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Sequence matched median PaO2 per dose cohort comparing TSC vs PBO
Time Frame: Up to 10 ± 1 minutes after final VO2 max
Comparison of partial pressure of oxygen (PaO2) at altitude between control and experimental exposures
Up to 10 ± 1 minutes after final VO2 max
Sequence matched median VO2 per dose cohort comparing TSC vs PBO
Time Frame: Up to 33 minutes (achievement of peak wattage)
Comparison of maximal oxygen consumption (VO2 max) at altitude between control and experimental exposures
Up to 33 minutes (achievement of peak wattage)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Effect of TSC on Median Oxygen Saturation
Time Frame: Up to 33 minutes (achievement of peak wattage)
Comparison of oxygen saturation (SpO2) between the control and experimental exposures
Up to 33 minutes (achievement of peak wattage)
