About this study

Official title: 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.

Read the 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.

What is being measured

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

  1. Postoperative Blood Loss After Surgery (Estimated Blood Loss (EBL))

    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.

    Measured: Within 24 hours of surgery

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing RiaStAP and Saline in people with Hypofibrinogenemia and Afibrinogenemia, run by Nicklaus Children's Hospital f/k/a Miami Children's Hospital at 2 sites in United States.

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

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. 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 16 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 16 Sep 2021). 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?

Postoperative Blood Loss After Surgery (Estimated Blood Loss (EBL)) (time frame: Within 24 hours of surgery). The study lists 15 primary outcomes in all. 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 NCT02822599, which also lists 10 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 16 Sep 2021.
