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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

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
Incidence of Pre-specified Infusion Associated Adverse Events
Time Frame: 24 hours

Any of the following occurring within 6 h of mesenchymal stem-cell infusion:

  • Addition of a third vasopressor or an increase in vasopressor dose greater than or equal to the following:
  • Norepinephrine: 10 μg per min
  • Phenylephrine: 100 μg per min
  • Dopamine: 10 μg/kg per min
  • Epinephrine: 0·1 μg/kg per min
  • Hypoxaemia requiring an increase in the fraction of inspired oxygen of ≥0·2 and increase in positive end-expiratory airway pressure level of 5 cm H2O or more to maintain transcutaneous oxygen saturations in the target range of 88-95%
  • New cardiac arrhythmia requiring cardioversion
  • New ventricular tachycardia, ventricular fi brillation, or asystole
  • A clinical scenario consistent with transfusion incompatibility or transfusion-related infection
  • Cardiac arrest or death within 24 h of mesenchymal stem-cell infusion
24 hours

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
Incidence of Severe Adverse Events (SAEs)
Time Frame: Investigators conducted daily assessments for the presence of adverse events (AE) from enrollment through study day 28 or hospital discharge, whichever occurred first.
The number of participants with a severe adverse event during the study was assessed.
Investigators conducted daily assessments for the presence of adverse events (AE) from enrollment through study day 28 or hospital discharge, whichever occurred first.
Ventilator Free Days at Study Day 28
Time Frame: time of initiating unassisted breathing to day 28
Ventilator Free Days (VFDs) to day 28 were defined as the number of days from the time of initiating unassisted breathing to day 28 after randomization, assuming survival for at least two consecutive calendar days after initiating unassisted breathing and continued unassisted breathing to day 28. If a subject received assisted breathing at day 27 or died prior to day 28, a value of zero VFDs was given.

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
