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.

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.

Placebo Comparator: 0.9% saline and sugar pill
100 ml of 0.9% saline (for i.v. Vitamin C) and a p.o. placebo (sugar pill for the p.o. Vitamin E) administered every 8 hours starting within one hour after admission to the Emergency department for up to 5 days or until discharge from the ICU, whichever comes first.

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
Number of Participants With Coagulation Abnormalities
Time Frame: From enrollment up to 3 days
Coagulation parameters are evaluated using standard functional tests (prothrombin time (PT), partial thromboplastin time (PTT), fibrinogen and platelet count)and point of care functional analysis using thromboelastogram (TEG-ROTEM). A blood sample is collected upon arrival in the emergency department at 0 hours only and analyzed for markers of activation of coagulation, inflammation, and levels of vitamin C/E.
From enrollment up to 3 days
Number of Subjects With Ventilator-associated Pneumonia.
Time Frame: From enrollment to 3 days
Number of subjects diagnosed with pneumonia and requiring ventilator support.
From enrollment to 3 days
Number of Subjects With Organ Injury
Time Frame: From enrollment to 3 days
Any injury to internal organs (thoracic, abdominal or cranial cavity)
From enrollment to 3 days
Number of Total Blood Product Transfusions
Time Frame: From enrollment to 3 days
the number of blood product transfusions for all subjects in each group over the course of 3 days.
From enrollment to 3 days

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
Number of Protocol Violations Per Arm.
Time Frame: from enrollment up to 60 days post enrollment
The number of times that there was a deviation or violation from how the protocol was to be implemented.
from enrollment up to 60 days post enrollment
Number of Subjects Surviving to Day 28
Time Frame: from enrollment up to 28 days post enrollment
Number of subjects that survived to day 28 after enrollment
from enrollment up to 28 days post enrollment
Number of Subjects With 60-day Survival
Time Frame: from enrollment up to 60 days post enrollment
Number of subjects in each arm that survived to day 60
from enrollment up to 60 days post enrollment
Mean Number of Ventilator-free Days for Subjects
Time Frame: from enrollment up to 60 days post enrollment
The mean number of ventilator free days (not on ventilator) for subjects in each arm
from enrollment up to 60 days post enrollment
Mean Number of Days in ICU.
Time Frame: from enrollment up to 60 days post enrollment
the mean number of days each subject was in the ICU in each arm
from enrollment up to 60 days post enrollment
Mean Number of Hospital Stay Days.
Time Frame: from enrollment up to 60 days post enrollment
The mean number of days subjects were in the hospital in each arm of the study

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
