Human Fibrinogen Concentrate in Pediatric Cardiac Surgery (RiaSTAP)

August 20, 2021 updated by: Christopher Tirotta, MD, MBA, Nicklaus Children's Hospital f/k/a Miami Children's Hospital

The Role of Human Fibrinogen Concentrate (RiaSTAP) in Decreasing Blood Loss and the Need for Component Blood Therapy in Infants Undergoing Cardiopulmonary Bypass.

The goal of the study is to determine whether the use of Human Fibrinogen Concentrate (RiaSTAP) will decrease blood loss and the need for component blood therapy in neonates and infants undergoing cardiopulmonary bypass.

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

The goal of the study is to determine whether the use of Human Fibrinogen Concentrate (RiaSTAP) will decrease blood loss and the need for component blood therapy in neonates and infants undergoing cardiopulmonary bypass. RiaSTAP will be administered after termination of Cardiopulmonary Bypass (CPB) at a dose of 70 mg/kg, in a prospective, randomized, controlled study. We hypothesize that the administration of RiaSTAP in this manner will reduce peri-operative bleeding and transfusion requirements.

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.

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.

Description

Inclusion Criteria:

  • Neonatal and infant cardiac patients presenting for open-heart surgery at Nicklaus Children's Hospital will be eligible for enrollment in the study.

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
Postoperative Blood Loss After Surgery (Estimated Blood Loss (EBL))
Time Frame: Within 24 hours of surgery
Primary outcome efficacy: Estimated blood loss (EBL); median; A transfusion algorithm was developed based on three previous studies, modified for pediatrics. Clinically significant bleeding requiring treatment was defined as a rate >10 cc kg-1 hr-1 calculated every 15 minutes while in the OR, measured by blood in the suction canister. In cases of continued bleeding following randomization to HFC or placebo, cryoprecipitate was considered for fibrinogen <200 mg/dL or FIBTEM MCF <7 mm. Thereafter, as per routine care, ROTEM analysis was performed at least every 30 minutes while in the OR, or sooner, at the discretion of the OR team. Once the patient left the OR, ROTEM was performed at least every 60 minutes for the first 6 hours or until clinically significant bleeding had stopped. Blood products transfused after CPB separation were based on a pre-defined protocol. Recommended volumes of each therapy were based on pre-defined formulae and a ROTEM analysis algorithm.
