Does Plasma Reduce Bleeding in Patients Undergoing Invasive Procedures

August 16, 2021 updated by: Jeffrey L Carson, MD, Rutgers, The State University of New Jersey
The purpose of this study is to evaluate prophylactic fresh frozen plasma transfusion in patients with moderately elevated international normalized ratios (INR) prior to undergoing an invasive procedure.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Fresh frozen plasma is used very frequently in the US. Many plasma transfusions are given prior to a procedure in order to correct perceived bleeding risk, yet there is little evidence to support that use of plasma reduces bleeding. There has never been an adequately powered trial to establish the efficacy of plasma and document the risks. This pilot study will evaluate the feasibility of conducting a research protocol that will lead to a large scale clinical trial designed to evaluate the treatment effectiveness of prophylactic plasma transfusion in patients with moderately elevated INRs prior to undergoing an invasive procedure outside of the operating room.

Study subjects will be randomly allocated to either receive either plasma transfusion prior to the procedure, or to no treatment. Study outcomes will be compared between the two study arms. Recruitment rates, protocol adherence, and rates of study outcomes will be assessed to determine the feasibility of the large scale trial.

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

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. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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
Change in Hemoglobin Level
Time Frame: within 2 days post procedure
Change from pre-procedure hemoglobin to lowest within 2 days after procedure
within 2 days post procedure

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.
