NCT06481995

Brief Summary

The goal of this trial is to determine if postpartum blood loss can be reduced by replenishing coagulation factor XIII (FXIII) at an early stage of postpartum hemorrhage (PPH). Summary of current body of evidence:

  • Morbidity and mortality due to PPH is rising.
  • Current guidelines focus on replenishment of fibrinogen as an initial step in the treatment of PPH-related coagulopathy, despite non-conclusive evidence in all prospective trials.
  • Trials from other specialties demonstrate a significant impact of FXIII on perioperative bleeding complications; a previous study at the University Hospital Zurich showed that pre-partum factor XIII activity had a strong association to postpartum blood loss. Therefore, this nationwide, multi-center, randomized, controlled trial in multiple perinatal centers across Switzerland will be conducted. The goal is to determine if postpartum blood loss and PPH-related complications can be reduced by replenishing FXIII. All participating women receive, according to the national guideline, 1g tranexamic acid (TXA) i.v. in case of PPH (measured blood loss \[MBL\] ≥ 500 mL) during the pre-study phase. Randomization takes place if bleeding continues and exceeds 700mL. The intervention group then receives FXIII (Fibrogammin®) according to approved dosage in addition to obstetric standard of care treatment for causes of PPH; the control group receives only standard of care treatment.

Outcome Measures

Primary Outcomes (1)

  • Blood Loss during post partum hemorrhage

    Measured blood loss, in ml

    Day 1 (within 24 hours after delivery)

Secondary Outcomes (7)

  • Outcome of postpartum hemorrhage

    Time point of assessment will be 48 hours (range 36 to 60) postpartum, if not stated otherwise

  • Changes in hematological standard value: hemoglobin

    shortly before delivery and 48 hours (range 36 to 60 hours) after delivery

  • Changes in hematological standard value: leucocyte count

    shortly before delivery and 48 hours (range 36 to 60 hours) after delivery

  • Changes in hematological standard value; thrombocyte count

    shortly before delivery and 48 hours (range 36 to 60 hours) after delivery

  • Hospital costs

    from admission to hospital until hospital discharge, up to 9 weeks

  • +2 more secondary outcomes

Other Outcomes (1)

  • Thromboembolic events

    6 - 9 weeks after delivery (visit 4)

Study Arms (2)

Fibrogammin (FXIII)

EXPERIMENTAL

Women in the intervention group receive FXIII intravenously in addition to the standard of care treatment for PPH. FXIII is administered when blood loss is \> 700 ml. Women weighing \<80 kg receive 1250 IU Fibrogammin®; women weighing 80-99.9 kg receive 1500 IU Fibrogammin®; thus ensuring a dose of 15-20 IU FXIII per kg body weight according to the manufacturer's recommendation.

Drug: Fibrogammin

Control

NO INTERVENTION

Women in the control group will be treat according to the standard of care procedure for PPH.

Interventions

Fibrogammin is administered according to the Summary of product characteristics (SmPC) after measured blood loss exceeds 700 ml and bleeding is ongoing

Also known as: Factor XIII
Fibrogammin (FXIII)

Data Sharing

IPD Sharing
Will share

The data sharing plan aims to ensure computational reproducibility of all published research findings obtained from data collected in this trial. Each publication will be accompanied by a dedicated compendium containing deidentified individual patient data necessary to independently reproduce the analyses presented in the corresponding publication. Such a compendium also contains information about the computer code that was used to generate figures, tables, and other statistical output. Distribution will be via a data repository following FAIR principles (such as zenodo.org).
