About this study

Official title: Prehospital Air Medical Plasma (PAMPer) Phase III Multicenter, Prospective, Randomized, Open-label, Interventional Trial A Four Year Multicenter Open Label Randomized Trial

To determine the effect of the prehospital infusion during air transport of 2 units of AB plasma on 30 day mortality in patients with hemorrhagic shock as compared to conventional care.

Read the detailed description

Background: Although advances in the care of the severely injured patient have occurred over the last decade, patients continue to be plagued with uncontrolled hemorrhage resulting in significant early mortality and the development of multiple organ failure and associated complications. A primary driving force for this unbridled hemorrhage has been shown to be the early coagulopathy which complicates severe injury. Increasing evidence suggests that blood component transfusion protocols that address this early coagulopathy, once a patient arrives at a trauma center, are associated with lower mortality and a reduction in blood component transfusion requirements. Prehospital interventions which quell this early coagulopathy in an earlier setting have the potential to minimize or even prevent this vicious hemorrhagic cascade, further lowering blood component transfusion requirements and reducing the resultant morbid sequelae which complicates severe injury.

Objective/Hypothesis: The primary hypothesis will be that prehospital infusion of plasma during air medical transport in patients with hemorrhagic shock will lower 30 day mortality. The secondary hypotheses include that prehospital infusion of plasma will reduce 24 hour blood transfusion, multiple organ failure, nosocomial infection, and acute lung injury, reduce or prevent the early coagulopathy as demonstrated by improving presenting coagulation and thromboelastography parameters, and reduce the early inflammatory cytokine response, thrombomodulin and increase protein C levels.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Our Primary Outcome for the Proposal Will be 30 Day Mortality

    All cause 30 day mortality using imputation for those with missing 30 day mortality.

    Measured: 30 days

Secondary outcomes (4)

  1. Twenty Four-Hour Blood Transfusion Requirements

    24-hour blood transfusion requirements will be determined by recording blood volume (mls) and number of Units transfused from the time of trauma bay arrival or upon completion of pre-hospital initiated plasma infusion. For survival bias analysis, volumes and number of blood transfusion Units received at 3, 6, 12, and 18 hours will also be recorded.

    Measured: at twenty four hours

  2. In-hospital Mortality

    In hospital mortality will be prospectively recorded from the time of trauma bay arrival. Over the first 24 hours we will document and record the time of death in hours, while after the 24 hour time point, we will document and record the time of death in days from arrival. We suspect that patients in hemorrhagic shock will have a significant percentage of mortality occurring in the first 24 hour period.

    Measured: during hospitalization

  3. Multiple Organ Failure

    Organ dysfunction will be evaluated via a well-validated scoring system referred to as the Multiple Organ Dysfunction Score (MODScore). Patients who are never admitted to the ICU or those with a length of ICU stay of less than 48 hours will be considered to have a MODScore of 0. A summary of the MODScore may be calculated by summing the worst scores of each of the individual systems over the course of the ICU stay (Table 1). A summary MODScore > 5 will be classified as multiple organ failure (MOF). Scores will be determined daily up until post injury day 28 or ICU discharge.

    Measured: during hospitalization

  4. Acute Lung Injury (ALI) and Transfusion Related Acute Lung Injury (TRALI)

    Development of ALI will be assessed which includes: 1) bilateral infiltrates on chest x-ray, 2) a capillary wedge pressure < 18mmHg, and 3) Pao2/Fio2 ratio < 300 via blood gas analysis. In those patients without a Swan-Ganz catheter to determine capillary wedge pressure, the absence of signs of, or clinical concern, for elevated left sided atrial pressures will be used for the diagnosis. All patients who remain intubated beyond the first 24 hours post-injury will be evaluated using blood gas analysis and chest x-ray evaluation. Those patients who remain intubated at 48 hours through 7 days will be reevaluated for this outcome at these time points. The diagnosis of TRALI will be defined as when ALI occurs within the first 6 hours from arrival at the trauma center as it is clinically defined.

    Measured: hospitalization

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 9 Oct 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Our Primary Outcome for the Proposal Will be 30 Day Mortality (time frame: 30 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01818427, which also lists 7 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Apr 2021.
